Description

Technical Field

[0001] This invention belongs to the field of anchor bolt processing technology, and more specifically, relates to a slotted anchor bolt processing system and processing technology. Background Technology

[0002] Slotted anchor bolts are steel pipe support components with longitudinal slots along their length. Production typically involves sequential steps including bolt loading, slot adjustment, ring fitting, diameter reduction, ring positioning, and welding. Existing production lines often use manual handling, ordinary chutes, or single conveyor belts for bolt transfer. Long tubular bolts are prone to stacking, deflection, and jamming during loading, and it's inconvenient to remove abnormal materials such as double stacks online. After slot adjustment, if reliable stepping and posture maintenance are lacking during transfer to the ring fitting, diameter reduction, and welding stations, the slot direction can easily shift again, leading to unstable relative positions between the retaining ring notch and the bolt slot, affecting subsequent welding quality. Furthermore, retaining ring loading often relies on manual placement or simple gravity dropping, which can cause rolling, jamming, and inaccurate notch direction. Using steel wire for on-site ring punching presents risks such as inaccurate wire length, ring position deviation, and mold jamming. Furthermore, if the retaining ring cannot be accurately pushed to the preset position along the axial direction of the rod after the ring is completed, the positional consistency of the anchor rings in the same batch will be poor, making it difficult to adapt to automatic welding. Summary of the Invention

[0003] This invention provides a pipe-slot anchor processing system and process. Through the integrated linkage of stepped feeding, pipe slot adjustment, collar positioning, welding and stacking, the system achieves orderly screening and feeding of the anchor body, stable transport and automatic positioning of the collar welding, thereby avoiding problems such as abnormal materials, pipe slot offset and inconsistent collar position.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A pipe-slot anchor bolt processing system and processing technology are provided, including a stepped rod mounting device, a linkage device, a collar device, a welding auxiliary device, a welding device, and a stacking device. The stepped rod mounting device includes multiple sets of spaced stepped fixed plates, stepped moving plates, a material dropping plate, and a weighing sensor. The stepped moving plate is used to push the rod body upwards step by step along the stepped fixed plate. The weighing sensor is located at the top step of the stepped fixed plate. The material dropping plate is rotatably connected to the stepped fixed plate and has a loading state for the docking linkage device and a discharge state for the docking non-conforming area. The linkage device includes multiple sets of conveying mechanisms, a pipe-slot adjustment assembly, a sliding frame, a first lifting assembly, a second lifting assembly, and a positioning and diameter reduction assembly. The multiple sets of conveying mechanisms receive the material dropping plate. The output rod body; the pipe gap adjustment assembly, the collar device, and the welding auxiliary device are arranged sequentially in the direction away from the step-mounting device, and the stacking equipment is located downstream of the welding auxiliary device; the conveying mechanism is also used to receive the welded rod body and transport it to the stacking equipment; the positioning and diameter reduction assembly is arranged opposite to the collar device, the sliding frame slides along the transport direction of the conveying mechanism, and the first lifting assembly and the second lifting assembly are connected to the sliding frame at intervals; the collar device is used to put a collar on one end of the rod body after adjusting the pipe gap, and the collar device is one of the collar correction device, automatic collar punching device, or feeding device; the welding auxiliary device includes a collar positioning assembly and a pushing assembly arranged opposite to each other, and the welding device is located on one side of the collar positioning assembly for welding the retaining ring to the rod body.

[0005] In one possible implementation, the step-up pole device further includes a stop assembly connected to the step plate. The stop assembly includes a driver, a telescopic rod, and a through-fitting device. The through-fitting device is connected to the step plate. The telescopic rod slides through the through-fitting device and is connected to the power output end of the driver. When the upper end of the telescopic rod extends above the step plate, it blocks the pole at the top step so that the load cell weighs the pole.

[0006] In one possible implementation, a pusher is connected between the discharge plate and the stepped stationary plate, with the stepped stationary plate and the discharge plate respectively hinged at both ends of the pusher; a weighing sensor is electrically connected to a controller, and the controller controls the pusher to extend and retract according to the weighing signal from the weighing sensor, so that the discharge plate is kept in the feeding state or rotated to the discharge state.

[0007] In one possible implementation, the stepped moving plate is connected to a power unit, which drives the stepped moving plate to move intermittently back and forth; there are two sets of stepped fixed plates and stepped moving plates, which are spaced apart, and the two sets of stepped moving plates move synchronously to push the same rod.

[0008] In one possible implementation, a limiting member is provided on the side of the conveying mechanism. When the rod moves with the conveying mechanism and abuts the limiting member, it is located on the upstream side of the limiting member along the conveying direction. A limiting sensor is connected to the side of the limiting member. The limiting sensor is used to detect when the rod reaches the pipe gap adjustment position and is linked with the first lifting assembly.

[0009] In one possible implementation, both the first lifting assembly and the second lifting assembly include a telescopic member connected to a sliding frame and arranged vertically, and a clamping member connected to the upper end of the telescopic member. The clamping member is used to enclose the pole body and give the pole body a circumferential rotational degree of freedom and a axial movement degree of freedom within the clamping member.

[0010] In one possible implementation, the distance between the first lifting assembly and the second lifting assembly is equal to the distance between the pipe gap adjustment assembly and the collar device, and also equal to the distance between the collar device and the welding auxiliary device; the first lifting assembly is used to transfer the rod between the pipe gap adjustment station and the collar station, the second lifting assembly is used to transfer the rod between the collar station and the welding station, and is used to release the rod onto the conveying mechanism after the welding is completed.

[0011] In one possible implementation, the pipe gap adjustment assembly includes an elastic limiting mechanism and a pushing and rotating mechanism. The elastic limiting mechanism includes a base, multiple springs, and a rotating disk. The multiple springs are connected between the base and the rotating disk, and the rotating disk is used to elastically abut one end of the rod. The pushing and rotating mechanism includes a first slide rail, a first electrically controlled slide table, and a rotating table. The first electrically controlled slide table is slidably connected to the first slide rail and its sliding direction is parallel to the axial direction of the rod. The rotating table is connected to the first electrically controlled slide table and is used to drive the rod to rotate circumferentially after abutting the other end of the rod.

[0012] In some embodiments, the rotating end of the rotary table has a first cone at its center, the tip of the first cone facing the rod, the outer wall of the first cone abutting against the end of the rod, and a portion of the first cone being able to be inserted into the rod.

[0013] In one possible implementation, the positioning and reducing assembly includes a positioning platform that slides parallel to the axial direction of the rod, a hollow cylinder connected to the upper end of the positioning platform, a reducing die connected to the push end of the hollow cylinder, and a fixing rod inserted inside the hollow cylinder. A conical cavity is formed inside the reducing die, and the fixing rod is used to abut against the end of the rod to disengage the rod from the reducing die when the hollow cylinder drives the reducing die to move in the opposite direction.

[0014] In one possible implementation, the collar positioning assembly of the welding auxiliary device includes a second cone and a sleeve. The tip of the second cone faces the rod body, and a portion of the second cone is used to insert into the rod body along the axial direction. The sleeve is fitted onto the second cone and forms a gap between it and the outer wall of the second cone. One end of the rod body is used to insert into the gap. A retaining ring on the rod body is positioned on the side of the sleeve closer to the rod body, so that the retaining ring is positioned at a preset position in the axial direction of the rod body.

[0015] In some embodiments, the collar positioning assembly further includes a rotating part having a circumferentially rotating end. The rotating end is connected to the thick end of the second cone and is coaxially arranged with the second cone. After the pushing assembly clamps the rod body with the second cone, the rotating part is used to drive the second cone and the rod body to rotate circumferentially to cooperate with the welding device to weld the retaining ring and the rod body.

[0016] In one possible implementation, the pushing assembly includes a second slide rail and a positioning slide. The positioning slide is slidably connected to the second slide rail and is connected to a receiving cylinder that moves along a direction parallel to the rod axis. The receiving cylinder has a circumferential rotational degree of freedom. One end of the rod near the receiving cylinder is used to insert into the receiving cylinder. The receiving cylinder moves towards the collar positioning assembly by means of the sliding pushing rod of the positioning slide to form a clamping of the rod with the collar positioning assembly. The positioning slide is connected to a flat top member that pushes the receiving cylinder along a direction parallel to the rod axis. The pushing tip of the flat top member is rotatably connected to the receiving cylinder.

[0017] In some embodiments, the positioning slide is connected to a vertical top member, the lower end of which has a vertical degree of freedom of movement. The lower end of the vertical top member is connected to two sets of grippers that cooperate to form a clamping state or a disengaged state. When the two sets of grippers are in the clamping state, they are used to clamp the end of the rod so that the receiving cylinder moves away from the rod under the drive of the flat top member and disengages from the rod. When the two sets of grippers switch to the disengaged state and disengage from the rod, the vertical top member drives the two sets of grippers to move upward and away from the rod so that the second lifting assembly places the rod on the conveying mechanism and moves it to the next working position.

[0018] In one possible implementation, when the ring-clamping device is an upper ring correction device, the upper ring correction device includes a housing, a conveying assembly, and a ring-taking assembly. An upper ring sleeve extending horizontally is provided on one side of the housing. The conveying assembly is located on the top of the housing and extends along the central axis of the upper ring sleeve. The ring-taking assembly is rotatably connected to the discharge end of the conveying assembly. The ring-taking assembly has a picking element and is used to pick up the retaining ring on the conveying assembly and then swing it vertically downward to send the retaining ring into the upper ring sleeve.

[0019] In some embodiments, a rotating member is rotatably connected to the housing and extends through the housing along the axial direction of the upper ring sleeve. An adsorption member is provided at one end of the rotating member located inside the upper ring sleeve. A notch extending through the upper and lower parts of the upper ring sleeve is provided, and an alignment detection member facing the notch is provided on the housing. A sliding member extends through the rotating member axially, and a collar detection member located at the end of the sliding member's movement path is provided on the housing.

[0020] In one possible implementation, when the ring-forming device is an automatic ring-forming device, the automatic ring-forming device includes a frame, a wire feeding assembly, a hook forming assembly, a cutting and bending assembly, a lower arc die, and an upper arc die; one side of the frame is provided with an insertion sleeve for the wire to pass through, and the wire feeding assembly is located on the side of the frame near the insertion sleeve; the hook forming assembly is rotatably connected to the frame and has a swing hook capable of swinging to below the wire; the cutting and bending assembly is slidably connected to the frame in the vertical direction, and when the cutting and bending assembly descends... It is used to cut steel wire and press the cut steel wire down onto the swing hook to form an inverted U-shaped material; the lower arc mold is located at the bottom of the frame and below the hook forming assembly, and the upper arc mold is slidably connected to the frame in the vertical direction and located above the hook forming assembly; the hook forming assembly can be detached from the inverted U-shaped material after it is formed, so as to avoid the upper arc mold pushing the inverted U-shaped material into the lower arc mold, so that the upper arc mold and the lower arc mold cooperate to squeeze the inverted U-shaped material into a ring on the outer periphery of the rod.

[0021] In some embodiments, the cutting and bending assembly has a guide platform extending vertically on the side near the hook forming assembly. The hook forming assembly slides with the guide platform. A horizontally extending mounting shaft is provided on the frame, and a torsion spring is sleeved on the mounting shaft, with its two ends connecting the frame and the hook forming assembly respectively. When the cutting and bending assembly descends and the guide platform keeps the swing hook below the wire, the cutting and bending assembly bends the wire onto the swing hook to form an inverted U-shaped material. When the cutting and bending assembly continues to descend until the hook forming assembly disengages from the guide platform, the torsion spring causes the hook forming assembly to swing outward. This allows the swing hook to disengage from the inverted U-shaped material. The bottom surface of the upper arc mold is provided with an upwardly arched first arc groove. The bottom surface of the cutting and bending assembly has two extension arms located on both sides of the first arc groove and extending downward. The adjacent side walls of the two extension arms are provided with first forming grooves extending in the vertical direction. The bottom surface of the extension arms is provided with a second forming groove that communicates with the first forming groove. The two first forming grooves and the first arc groove form an inverted U-shaped groove. The top surface of the lower arc mold is provided with a downwardly recessed second arc groove. The first arc groove and the second arc groove are used for mold closing and extruding the inverted U-shaped material into a ring.

[0022] In one possible implementation, when the collar device is a feeding device, the feeding device includes a mounting base, a collar rod, a pusher, a first drive assembly, and a receiving member. The collar rod is horizontally arranged with one end in the length direction being the first end. The collar rod is used to sleeve multiple retaining rings. The pusher can move along the length direction of the collar rod. The first drive assembly is used to drive the pusher to push the retaining rings towards the first end. The receiving member is fixed on the mounting base and has a receiving groove with the opening facing upward. The receiving groove is located below the collar rod and is used to receive the retaining rings falling from the first end.

[0023] In some embodiments, the sidewall of the collar rod has a radially outwardly protruding limiting portion that extends along the length of the collar rod and is used to pass through the slot of the retaining ring; the feeding device also includes a position sensor and a positioning rod that slides through the receiving member and triggers the position sensor when pushed by the rod body passing through the retaining ring in the receiving groove.

[0024] This invention also provides a process for processing using a slotted anchor bolt processing system, comprising the following steps: S1. Step feeding of the rod: The step moving plate intermittently pushes the rod to move up the step fixed plate step by step. After the rod reaches the top step of the step fixed plate, the weighing sensor weighs the rod. S2, Rod diversion: Based on the weighing signal from the weighing sensor, it is determined whether the rod is qualified. Qualified rods enter the conveying mechanism through the feeding plate, while unqualified rods enter the unqualified area through the discharging plate. S3. First rod gap adjustment: After the first rod falls onto the conveying mechanism and is conveyed to the gap adjustment station, the first lifting component goes to the gap adjustment station to grab the first rod, and the gap adjustment component adjusts the gap of the first rod. S4. The first rod is moved to the collar station and the diameter reduction station: After the pipe seam of the first rod is adjusted, the first lifting component grabs the first rod and moves it with the sliding frame to the collar station and the diameter reduction station. The collar device collars one end of the first rod, and the positioning and diameter reduction component reduces the diameter of the other end of the first rod. S5. The second rod's pipe gap adjustment and handover with the first rod: The first lifting assembly releases the first rod and returns to the pipe gap adjustment position with the sliding frame to grab the second rod, while the second lifting assembly grabs the first rod; the first lifting assembly, in conjunction with the pipe gap adjustment assembly, adjusts the pipe gap of the second rod and completes the collar and diameter reduction of the first rod. S6. Synchronous step-by-step transfer: After the second rod's pipe seam adjustment is completed and the first rod's collar and diameter reduction are completed, the first lifting assembly and the second lifting assembly move synchronously with the sliding frame. The first lifting assembly transfers the second rod to the collar station and the diameter reduction station, and the second lifting assembly transfers the first rod to the welding station. S7. Synchronous processing: The second rod is simultaneously fitted with a ring and reduced in diameter at the ring-closing station and the diameter-reducing station. At the welding station, the first rod is pushed towards the ring-closing positioning assembly by the pusher assembly, so that the retaining ring on the first rod is positioned in the preset position, and the retaining ring is welded to the first rod by the welding device. S8. Finished product conveying and palletizing: After the first rod has completed all the processing steps, the second lifting component releases the first rod, causing it to fall onto the conveying mechanism, which then transports the first rod to the palletizing equipment. S9. Cyclic processing: After steps S7 and S8 are completed, the first lifting assembly and the second lifting assembly return synchronously with the sliding frame. The first lifting assembly returns to the pipe seam adjustment station to grab the next rod. The second lifting assembly grabs the rod located at the collar station and the diameter reduction station and has completed the collaring and diameter reduction. Then, steps S6 to S9 are repeated.

[0025] In one possible implementation, in steps S1 to S2, the telescopic rod of the stop rod assembly extends and blocks the rod body from stopping at the top step of the stepped plate. After the weighing sensor obtains the weighing signal, the controller determines whether the weight of the rod body is within the preset weight threshold range. If it is within the preset weight threshold range, the telescopic rod retracts and the discharge plate remains in the feeding state. If it exceeds the preset weight threshold range, the pusher drives the discharge plate to rotate to the discharge state.

[0026] In one possible implementation, during the pipe gap adjustment process, after the rod reaches the limiting member, the first lifting assembly rises and is surrounded by the clamping member; the first electrically controlled slide table drives the rotary table to approach along the axial direction of the rod, the first cone of the rotary table abuts against the end of the rod and pushes the rod towards the rotating disk of the elastic limiting mechanism, and the rotary table drives the rod to rotate to the preset position of the pipe gap.

[0027] In one possible implementation, in step S7, the positioning slide moves along the second slide rail toward the collar positioning assembly, causing the end of the rod to be inserted into the receiving cylinder; the flat top member continues to push the receiving cylinder and the rod toward the collar positioning assembly, causing the end of the rod to be inserted into the gap between the second cone and the sleeve, and the retaining ring is limited to a preset position in the axial direction of the rod by the side of the sleeve in the collar positioning assembly that is closer to the rod; the rotating part drives the second cone and the rod to rotate circumferentially, and the welding device performs circumferential welding on the retaining ring and the rod; after welding is completed, the two sets of grippers switch to the clamping state to clamp the end of the rod, the positioning slide moves away from the collar positioning assembly, causing the rod to disengage from the second cone, the flat top member retracts and causes the receiving cylinder to disengage from the rod, and then when the two sets of grippers switch to the separation state and disengage from the rod, the vertical top member drives the two sets of grippers to move upward and away from the rod, and the second lifting assembly places the rod on the conveying mechanism and moves it to the next working position.

[0028] In one possible implementation, during the ring-fitting process, when the ring-fitting device is an upper ring correction device, the conveying component transports the retaining ring to the discharge end, the ring-picking component picks up the retaining ring through the picking component and vertically swings it into the upper ring sleeve, the rotating component drives the retaining ring to rotate through the adsorption component, so that the notch of the retaining ring is aligned with the notch of the upper ring sleeve, the rod is inserted into the retaining ring in the upper ring sleeve and pushes the sliding component to trigger the ring-fitting detection component to complete the ring-fitting.

[0029] In one possible implementation, during the ring-forming process, when the ring-forming device is an automatic ring-forming device, the wire feeding assembly conveys the steel wire to the area below the cutting and bending assembly. The cutting and bending assembly descends to cut the steel wire and presses it down onto the swing hook to form an inverted U-shaped material. After the hook forming assembly swings outward to avoid the impact, the upper arc mold descends and cooperates with the lower arc mold to compress the inverted U-shaped material into a ring and secure it to the outer periphery of the rod.

[0030] In one possible implementation, during the ring-jointing process, when the ring-jointing device is a feeding device, the first driving component drives the pushing member to move along the ring-jointing rod and push multiple retaining rings towards the first end, so that the retaining rings fall sequentially from the first end into the receiving groove of the receiving member; the rod passes through the retaining rings in the receiving groove and pushes the positioning rod, and the positioning rod stops the axial movement of the rod after triggering the position sensor, so that the retaining ring is located in the preset position of the rod.

[0031] The beneficial effects of the pipe-slot anchor processing system provided by this invention are as follows: Compared with the prior art, the stepped rod loading device can realize the sequential, orderly, and screening feeding of rods, avoiding abnormal rods from entering subsequent processes; the linkage device can maintain the circumferential posture stability of the rods during station transfer, reducing pipe-slot direction deviation; the collar device can select a collar correction device, an automatic collar punching device, or a feeding device according to production needs, adapting to different production methods; the welding auxiliary device can uniformly position the axial position of the collar before welding, improving welding consistency; the processed rods fall directly back to the conveying mechanism and are transported to the stacking equipment, reducing manual handling and improving the automation level of the entire line.

[0037] Please see Figures 1 to 47The present invention describes the pipe-slot anchor processing system and processing technology. The pipe-slot anchor processing system includes a stepped rod mounting device 1, a linkage device 2, a collar device 3, a welding auxiliary device 4, a welding device 5, and a stacking device 6. The stepped rod mounting device 1 includes multiple sets of spaced stepped fixed plates 11, stepped moving plates 12, a material dropping plate 13, and a weighing sensor 14. The stepped moving plate 12 is used to push the rod body 7 upwards step by step along the stepped fixed plate 11. The weighing sensor 14 is located at the top step of the stepped fixed plate 11. The material dropping plate 13 is rotatably connected to the stepped fixed plate 11 and has a feeding state for the docking linkage device 2 and a discharging state for the docking non-compliance area. The linkage device 2 includes multiple sets of conveying mechanisms 21, a pipe-slot adjustment assembly 22, a sliding frame 24, a first lifting assembly 25, a second lifting assembly 26, and a positioning and diameter reduction assembly 27. The multiple sets of conveying mechanisms 21 receive the rod body 7 output from the material dropping plate 13. The pipe-slot adjustment assembly... 22. The collar device 3 and the welding auxiliary device 4 are arranged sequentially in a direction away from the step-up rod device 1, and the stacking device 6 is located downstream of the welding auxiliary device 4; the conveying mechanism 21 is also used to receive the welded rod 7 and convey it to the stacking device 6; the positioning and diameter reduction assembly 27 is arranged opposite to the collar device 3, the sliding frame 24 slides along the conveying direction of the conveying mechanism 21, and the first lifting assembly 25 and the second lifting assembly 26 are connected to the sliding frame 24 at intervals; the collar device 3 is used to put a collar on one end of the rod 7 after adjusting the pipe gap, and the collar device 3 is one of the collar correction device 31, the automatic ring punching device 32, or the feeding device 33; the welding auxiliary device 4 includes a collar positioning assembly 41 and a pushing assembly 42 arranged opposite to each other, and the welding device 5 is located on one side of the collar positioning assembly 41 and is used to weld the retaining ring 8 to the rod 7.

[0038] The welding device 5 and the palletizing equipment 6 are existing technologies and will not be described in detail here.

[0039] This application provides a pipe-slot anchor processing system. In actual use, the rod 7 to be processed first enters the stepped rod mounting device 1. The stepped moving plate 12 pushes the rod 7 upwards step by step along the stepped fixed plate 11. After the rod 7 reaches the top step, it is weighed by the weighing sensor 14. If the weight of the rod 7 is within the preset range for a single rod 7, the material drop plate 13 remains in the loading state, and the rod 7 rolls down to the conveying mechanism 21. If the weighing result shows that the rod 7 is double-stacked material, adhered material, or other abnormal material, the material drop plate 13 rotates to the discharge state, and the abnormal rod 7 is discharged into the unqualified area. After the qualified rod 7 falls to the conveying mechanism 21, it is sent to the pipe-slot adjustment station by the conveying mechanism 21. The first lifting component 25 grabs the rod 7 and, together with the pipe-slot adjustment component 22, rotates the longitudinal pipe slot of the rod 7 to the preset direction. Then, the first lifting component 25 moves with the sliding frame 24, sending the rod 7 to the collar station and the diameter reduction station. The collar device 3 applies a collar to one end of the rod 7, while the positioning and diameter reduction assembly 27 reduces the diameter of the other end of the rod 7. After the collar application and diameter reduction are completed, the second lifting assembly 26 delivers the rod 7 to the welding station, and the pushing assembly 42 pushes the rod 7 axially, causing the collar to abut against the collar positioning assembly 41 and be positioned at a preset position on the rod 7. Subsequently, the welding device 5 welds the retaining ring 8 and the rod 7. After welding is completed, the second lifting assembly 26 releases the rod 7, which falls back to the conveying mechanism 21 and is then conveyed by the conveying mechanism 21 to the palletizing equipment 6.

[0040] In a production line, the first lifting assembly 25 and the second lifting assembly 26 can work alternately and synchronously. The first lifting assembly 25 is responsible for sending the rod 7 located at the pipe gap adjustment station to the collar station and the diameter reduction station, while the second lifting assembly 26 is responsible for sending the rod 7 located at the collar station and the diameter reduction station to the welding station, and releasing the rod 7 onto the conveying mechanism 21 after welding is completed. Pipe gap adjustment, collaring, diameter reduction, welding, and unloading and stacking can be carried out in parallel on different rods 7, thus forming continuous processing of the rod 7.

[0041] Compared with the prior art, the pipe-slot anchor processing system provided in this embodiment has the following advantages: the stepped rod feeding device 1 enables the sequential, orderly, and screened feeding of rods 7, preventing abnormal rods 7 from entering subsequent processes; the linkage device 2 can maintain the circumferential posture stability of the rods 7 during station transfer, reducing pipe-slot direction deviation; the collar device 3 can select the collar correction device 31, automatic collar punching device 32, or feeding device 33 according to production needs, adapting to different production methods; the welding auxiliary device 4 can uniformly position the axial position of the collar before welding, improving welding consistency; after processing, the rods 7 fall directly back to the conveying mechanism 21 and are transported to the stacking device 6, reducing manual handling and improving the automation level of the entire line.

[0042] In one possible implementation, the aforementioned stepped upper rod device 1 adopts the following... Figures 1 to 7 , Figure 9 and Figure 10 The structure shown is described in the following document. Figures 1 to 7 , Figure 9 and Figure 10 The step-up device 1 also includes a stop rod assembly 15, which is connected to the step plate 11. The stop rod assembly 15 includes a driver 151, a telescopic rod 152, and a through-fitting kit 153. The through-fitting kit 153 is connected to the step plate 11. The telescopic rod 152 slides through the through-fitting kit 153 and is connected to the power output end of the driver 151. When the upper end of the telescopic rod 152 extends above the step plate 11, it blocks the rod 7 at the top step so that the weighing sensor 14 weighs the rod 7.

[0043] Specifically, the step-up device 1 also includes a stop rod assembly 15. After the rod 7 is pushed to the top step of the step stationary plate 11 by the step moving plate 12, the driver 151 drives the telescopic rod 152 to move upward. Guided by the through-fitting device 153, the telescopic rod 152 extends above the step stationary plate 11, preventing the rod 7 from rolling down. At this time, the rod 7 is stably stopped at the position corresponding to the weighing sensor 14. After the weighing sensor 14 completes the weighing, the controller decides whether to release the rod 7 based on the weighing result. If the rod 7 is qualified, the telescopic rod 152 retracts, and the rod 7 rolls towards the discharge plate 13; if the rod 7 is unqualified, the discharge plate 13 first switches to the discharge state, and then releases the rod 7.

[0044] The stop rod assembly 15 ensures that the rod 7 has a stable dwell time at the weighing position, preventing inaccurate data caused by the rolling of the rod 7; the through-piece 153 guides the telescopic rod 152, ensuring that the telescopic rod 152 extends and retracts smoothly, can withstand the impact of the rod 7 rolling down, and improves the reliability of the weighing diversion action.

[0045] In a preferred embodiment, the actuator 151 may employ a cylinder, electric cylinder, or hydraulic cylinder structure to obtain sufficient pushing speed and blocking force.

[0046] In one possible implementation, the aforementioned blanking plate 13 and stepped stationary plate 11 are adopted as follows: Figures 4 to 10 The structure shown is described in the following document. Figures 4 to 10 A pusher 16 is connected between the dropping plate 13 and the stepped plate 11. The two ends of the pusher 16 are respectively hinged to the stepped plate 11 and the dropping plate 13. The weighing sensor 14 is electrically connected to the controller. The controller controls the pusher 16 to extend and retract according to the weighing signal of the weighing sensor 14, so that the dropping plate 13 is kept in the feeding state or rotated to the discharge state.

[0047] Specifically, a pusher 16 is provided between the dropping plate 13 and the stepped stationary plate 11. The pusher 16 is hinged at both ends to the stepped stationary plate 11 and the dropping plate 13, respectively. When the pusher 16 extends or retracts, it causes the dropping plate 13 to swing around its rotating connection point. The controller receives the weighing signal from the weighing sensor 14 and compares the weighing signal with a preset weight threshold range. If the weight of the rod 7 is within the threshold range, the pusher 16 keeps the dropping plate 13 in the feeding state, and the rod 7 enters the conveying mechanism 21 along the dropping plate 13; if the weight of the rod 7 exceeds the threshold range, the pusher 16 drives the dropping plate 13 to rotate downwards to the discharge state, causing the rod 7 to enter the non-conforming area.

[0048] The material drop plate 13 achieves automatic switching through the pusher 16, eliminating the need for manual sorting. It can automatically separate qualified rods 7 from abnormal rods 7 at the feeding end, preventing double stacked materials from entering the pipe gap adjustment station and causing jamming or positioning errors.

[0049] In one possible implementation, the aforementioned stepped moving plate 12 adopts the following... Figure 4 , Figures 6 to 10 The structure shown is described in the following document. Figure 4 , Figures 6 to 10 The stepped moving plate 12 is connected to a power unit 17, which is used to drive the stepped moving plate 12 to move intermittently back and forth. There are two sets of stepped fixed plates 11 and stepped moving plates 12, which are spaced apart. The two sets of stepped moving plates 12 move synchronously to push the same rod 7.

[0050] Specifically, the movable step plate 12 is positioned on one side of the fixed step plate 11 or between two sets of fixed step plates 11, and its shape corresponds to that of the fixed step plate 11, having multiple progressively changing step structures. The movable step plate 12 is driven by the power unit 17 to move intermittently back and forth. The two sets of fixed step plates 11 and the two sets of movable step plates 12 are spaced apart along the length of the rod 7, with the same rod 7 simultaneously overlapping the two sets of fixed step plates 11. The power unit 17 drives the two sets of movable step plates 12 to move synchronously, each movement pushing the rod 7 upward by one step height. After the rod 7 reaches the corresponding step, it is supported by the fixed step plate 11.

[0051] Two sets of stepped moving plates 12 push synchronously, which can provide two-point support and synchronous lifting for the long rod 7, avoiding the rod 7 from tilting, flipping or getting stuck due to unilateral force; the intermittent action can separate the rods 7 one by one, improving the stability of the feeding cycle.

[0052] In a preferred embodiment, the power unit 17 may employ a cam mechanism, a servo-driven slide, a cylinder linkage mechanism, or other drive units capable of intermittent reciprocating motion to ensure that the stepped moving plate 12 has a stable displacement and thrust each time it is pushed. The two sets of stepped moving plates 12 can be mechanically synchronized through a transmission mechanism or electrically synchronized through a control system.

[0053] In one possible implementation, the aforementioned conveying mechanism 21 adopts, as shown in the example below. Figure 11 , Figure 12 and Figure 19 The structure shown is described in the following document. Figure 11 , Figure 12 and Figure 19 The conveying mechanism 21 is provided with a limiting member 211 on the side. When the rod 7 moves with the conveying mechanism 21 and abuts against the limiting member 211, it is located on the upstream side of the limiting member 211 along the conveying direction. The limiting member 211 is connected to a limiting sensor 212 on the side. The limiting sensor 212 is used to detect when the rod 7 reaches the pipe seam adjustment position and is linked with the first lifting assembly 25.

[0054] Specifically, the conveying mechanism 21 receives the qualified rod 7 output from the stepped rod device 1 and transports the rod 7 along the production line direction to the pipe gap adjustment station. To ensure that the rod 7 has a stable and uniform stopping position when entering the pipe gap adjustment station, a limiting member 211 is provided on the side of the conveying mechanism 21. Its position corresponds to the gripping starting point of the pipe gap adjustment station. When the rod 7 moves to this position along the conveying mechanism 21, the rod 7 stops against the limiting member 211 and is limited to the upstream side of the limiting member 211 along the conveying direction.

[0055] A limiting element 211 and a limiting sensor 212 are provided on the side of the conveying mechanism 21. After the rod 7 enters the conveying mechanism 21 from the drop plate 13, it moves downstream with the conveying mechanism 21. When the rod 7 moves to the pipe gap adjustment station, the rod 7 abuts against the limiting element 211 and stops on the upstream side of the limiting element 211. After the limiting sensor 212 detects that the rod 7 has reached the position, it sends a position signal to the controller, and the controller controls the first lifting assembly 25 to rise and grab the rod 7.

[0056] The limiting component 211 provides a mechanical stopping reference for the rod 7, and the limiting sensor 212 provides an electrical control signal reference, so that the first lifting assembly 25 can grab the rod 7 after it is in place, avoiding missing the grab, grabbing off-center, or entering the pipe gap adjustment action before the rod 7 has come to a complete stop.

[0057] In a preferred embodiment, the limiting member 211 may be a hook-shaped stop, a stop bar, or a vertical limiting block structure to accommodate the diameter of the rod 7 and the conveying posture. The limiting sensor 212 may be a proximity switch, a photoelectric switch, or a travel detection switch structure to achieve stable and reliable arrival detection.

[0058] In one possible implementation, the first lifting assembly 25 and the second lifting assembly 26 described above adopt the following... Figure 11 , Figure 12 , Figure 17 and Figure 20 The structure shown is described in the following document. Figure 11 , Figure 12 , Figure 17 and Figure 20 The first lifting assembly 25 and the second lifting assembly 26 both include a telescopic member 251 connected to the sliding frame 24 and arranged vertically, and a clamping member 252 connected to the upper end of the telescopic member 251. The clamping member 252 is used to surround the rod body 7, and to give the rod body 7 a circumferential rotational degree of freedom and a axial movement degree of freedom within the clamping member 252.

[0059] Specifically, both the first lifting assembly 25 and the second lifting assembly 26 include a telescopic member 251 and a clamping member 252. The telescopic member 251 is vertically mounted on the sliding frame 24, and the clamping member 252 is connected to the upper end of the telescopic member 251. When it is necessary to grasp the rod 7, the telescopic member 251 rises to bring the clamping member 252 close to the rod 7, and the clamping member 252 closes or surrounds the rod 7. When it is necessary to move the rod 7, the telescopic member 251 continues to support the rod 7 to disengage from the conveying mechanism 21, and the sliding frame 24 drives the first lifting assembly 25 and the second lifting assembly 26 to move to the next station. The clamping member 252 provides support for the rod 7, but does not completely lock the rod 7, allowing the rod 7 to rotate circumferentially within the clamping member 252, and also to move slightly axially during collar, diameter reduction, and welding positioning.

[0060] The first lifting assembly 25 and the second lifting assembly 26 can not only grasp the rod 7 and transport the workpiece, but also adapt to the rotational movement during pipe seam adjustment and the axial movement during collar, diameter reduction, and welding positioning, thus avoiding the impact of excessive clamping on subsequent processing.

[0061] In a preferred embodiment, the clamping member 252 may adopt a two-half clamping structure, an arc-shaped claw structure, or a flexible padding clamping structure to balance support stability with adaptability to rotation and axial movement. The telescopic member 251 may adopt a cylinder, electric cylinder, or hydraulic cylinder to meet different load and cycle requirements.

[0062] In one possible implementation, the first lifting assembly 25 and the second lifting assembly 26 are adopted as follows: Figure 11 and Figure 12 The structure shown is described in the following document. Figure 11 and Figure 12 The distance between the first lifting assembly 25 and the second lifting assembly 26 is equal to the distance between the pipe gap adjustment assembly 22 and the collar device 3, and equal to the distance between the collar device 3 and the welding auxiliary device 4. The first lifting assembly 25 is used to move the rod 7 between the pipe gap adjustment station and the collar station, and the second lifting assembly 26 is used to move the rod 7 between the collar station and the welding station, and to release the rod 7 onto the conveying mechanism 21 after the welding of the rod 7 is completed.

[0063] Specifically, the distance between the first lifting assembly 25 and the second lifting assembly 26 is equal to the distance between adjacent workstations. The first lifting assembly 25 reciprocates between the pipe seam adjustment workstation and the collaring workstation, while the second lifting assembly 26 reciprocates between the collaring workstation and the welding workstation. At the start of production, the first lifting assembly 25 first moves the first rod 7 from the pipe seam adjustment workstation to the collaring workstation; then the second lifting assembly 26 takes over the first rod 7, and the first lifting assembly 25 returns to grab the second rod 7. After the first rod 7 completes collaring and diameter reduction, and the second rod 7 completes pipe seam adjustment, the sliding frame 24 drives the first lifting assembly 25 and the second lifting assembly 26 to move synchronously, so that the first rod 7 enters the welding workstation, and the second rod 7 enters the collaring workstation and diameter reduction workstation. After welding is completed, the second lifting assembly 26 releases the rod 7, causing it to fall back to the conveying mechanism 21.

[0064] The two lifting components are arranged at equal intervals to achieve synchronous transfer of multiple workstations. Pipe gap adjustment, collar diameter reduction and welding processes can be carried out in parallel, which significantly shortens the waiting time of a single rod 7 and improves the overall line cycle time.

[0065] In one possible implementation, the aforementioned gap adjustment assembly 22 adopts the following... Figure 11 , Figure 12 and Figures 18 to 23 The structure shown is described in the following document. Figure 11 , Figure 12 and Figures 18 to 23 The pipe gap adjustment assembly 22 includes an elastic limiting mechanism 221 and a pushing and rotating mechanism 222. The elastic limiting mechanism 221 includes a base 2211, multiple springs 2212 and a rotating disk 2213. The multiple springs 2212 are connected between the base 2211 and the rotating disk 2213. The rotating disk 2213 is used to elastically abut one end of the rod 7. The pushing and rotating mechanism 222 includes a first slide rail 2221, a first electrically controlled slide table 2222 and a rotating table 2223. The first electrically controlled slide table 2222 is slidably connected to the first slide rail 2221 and the sliding direction is parallel to the axial direction of the rod 7. The rotating table 2223 is connected to the first electrically controlled slide table 2222 and is used to drive the rod 7 to rotate circumferentially after abutting the other end of the rod 7.

[0066] Specifically, the side of the rotating disk 2213 away from the spring member 2212 has a rotating surface 22131 that is rotatably connected to the rotating disk 2213 and can rotate circumferentially, for abutting and rotating with the rod 7. The pipe gap adjustment assembly 22 includes an elastic limiting mechanism 221 and a pushing and rotating mechanism 222. After the first lifting assembly 25 lifts the rod 7 to the adjustment height, the first electrically controlled slide 2222 drives the rotating platform 2223 to approach the rod 7 along the axial direction of the rod 7. The rotating platform 2223 abuts against one end of the rod 7 and pushes the rod 7 toward the rotating disk 2213 on the other side. The rotating disk 2213 is connected to the base 2211 through multiple spring members 2212 and can float elastically along the axial direction of the rod 7. After the rod 7 is clamped by the rotating platform 2223 and the rotating disk 2213, the rotating platform 2223 drives the rod 7 to rotate circumferentially until the pipe gap on the rod 7 rotates to the preset position.

[0067] The elastic limiting mechanism 221 can compensate for the length error of different rods 7 and prevent the rigid clamp from damaging the end of the rod 7; the rotating disk 2213 rotates with the rod 7, which can reduce frictional resistance and make the rotation adjustment of the rod 7 more stable.

[0068] In a preferred embodiment, multiple springs 2212 can be symmetrically distributed around the rotating disk 2213 to ensure that the rotating disk 2213 is subjected to uniform force; the first electrically controlled slide 2222 can adopt a linear module or a lead screw slide structure to obtain smooth propulsion and high repeatability positioning accuracy.

[0069] In some embodiments, see Figure 23 The rotating end 417 of the rotating platform 2223 has a first cone 2224 in the middle. The tip of the first cone 2224 faces the rod 7. The outer wall of the first cone 2224 is used to abut the end of the rod 7 and part of the first cone 2224 can be inserted into the rod 7.

[0070] Specifically, when the first electrically controlled slide 2222 drives the rotary table 2223 to approach the rod 7, the tip of the first cone 2224 first enters the inner hole of the rod 7. As the first electrically controlled slide 2222 continues to advance, the outer wall of the first cone 2224 contacts the end or inner wall of the rod 7 and forms a self-centering support. After the other end of the rod 7 abuts against the rotary disk 2213, the controller then allows the rotary table 2223 to start rotating.

[0071] The base 2211 is connected to a rotation sensor 2214, which is used to detect whether the rod 7 is in contact with the rotating disk 2213.

[0072] The first cone 2224 can adapt to rods 7 with different inner diameters or slight errors at the ends, and improve the coaxiality of the rod 7 and the rotary table 2223; the rotation sensor 2214 can prevent the rotary table 2223 from spinning freely when the rod 7 is not clamped, thus improving the safety of the adjustment action.

[0073] In one possible implementation, the aforementioned positioning and diameter reduction component 27 employs, as shown in... Figures 12 to 16 The structure shown is described in the following document. Figures 12 to 16 The positioning and reducing assembly 27 includes a positioning platform 271 that slides parallel to the axis of the rod 7, a hollow cylinder 272 connected to the upper end of the positioning platform 271, a reducing mold 273 connected to the push end of the hollow cylinder 272, and a fixing rod 276 passing through the hollow cylinder 272. A conical cavity is formed in the reducing mold 273. The fixing rod 276 is used to abut against the end of the rod 7 when the hollow cylinder 272 drives the reducing mold 273 to move in the opposite direction, so that the rod 7 can be dislodged from the reducing mold 273.

[0074] Specifically, the reducing die is connected to the piston rod of the hollow cylinder 272, and the fixing rod 276 is connected to the cylinder liner of the hollow cylinder 272 and passes through the piston rod, allowing the piston rod to move relative to the fixing rod 276.

[0075] The positioning and diameter reduction assembly 27 includes a positioning platform 271, a hollow hydraulic cylinder 272, a diameter reduction mold 273, and a fixing rod 276. After the rod 7 reaches the collar diameter reduction station, the positioning platform 271 moves axially along the rod 7, bringing the diameter reduction mold 273 closer to the end of the rod 7 to be reduced. The conical cavity of the diameter reduction mold 273 fits into the end of the rod 7. As the hollow hydraulic cylinder 272 or the positioning platform 271 continues to apply force, the end of the rod 7 is gradually squeezed into a diameter-reduced section by the conical cavity (the other end of the rod 7 is blocked by the collar device 3, i.e., the rod 7 will not move axially). After the diameter reduction and collaring are completed, the positioning platform 271 moves in the opposite direction to pull the rod 7 out of the collar device 3. Then, the piston rod of the hollow hydraulic cylinder 272 drives the diameter reduction mold 273 to move in the opposite direction, causing the fixing rod 276 to abut against the end of the rod 7, thus dislodging the rod 7 from the diameter reduction mold 273.

[0076] The positioning stage 271 can ensure that the diameter reduction mold 273 and the end of the rod 7 are accurately aligned. The diameter reduction mold 273 can stably form a tapered diameter reduction structure. The fixing rod 276 can assist in demolding and prevent the rod 7 from getting stuck in the diameter reduction mold 273, which would affect continuous production.

[0077] In one possible implementation, the welding auxiliary device 4 described above adopts, as follows: Figures 1 to 3 The structure shown is described in the following document. Figures 1 to 3 The collar positioning assembly 41 of the welding auxiliary device 4 includes a second cone 411 and a sleeve 412. The tip of the second cone 411 faces the rod 7, and part of the second cone 411 is used to insert into the rod 7 along the axial direction. The sleeve 412 is fitted onto the second cone 411 and forms a gap 413 between it and the outer wall of the second cone 411. One end of the rod 7 is used to insert into the gap 413. The retaining ring 8 on the rod 7 is limited to the side of the sleeve 412 close to the rod 7, so that the retaining ring 8 is positioned at a preset position in the axial direction of the rod 7.

[0078] Specifically, the collar positioning assembly 41 of the welding auxiliary device 4 includes a second cone 411 and a sleeve 412. After the rod 7 is delivered to the welding station by the second lifting assembly 26, the pushing assembly 42 pushes the rod 7 from the other end of the rod 7 toward the collar positioning assembly 41. The end of the rod 7 first contacts the tip of the second cone 411 and enters the gap 413 between the second cone 411 and the sleeve 412 along the second cone 411. The retaining ring 8 is stopped by the sleeve 412 when it moves with the rod 7 to the side of the sleeve 412 close to the rod 7. Since the depth of the end of the rod 7 entering the gap 413 is determined, the position where the retaining ring 8 is stopped is also determined, thereby placing the retaining ring 8 in a preset position in the axial direction of the rod 7.

[0079] The sleeve 412 serves as the axial positioning reference for the retaining ring 8, which can eliminate the problem of inconsistent positions when manually pushing the ring, making the welding position of the retaining ring of the same batch of anchor rods uniform and improving the consistency of finished product dimensions.

[0080] In some embodiments, see Figure 1 , Figure 2 and Figure 5 The collar positioning assembly 41 also includes a rotating part 416, which has a circumferentially rotating end 417. The rotating end 417 is connected to the thick end of the second cone 411 and is coaxially arranged with the second cone 411. After the pushing assembly 42 clamps the rod 7 with the second cone 411, the rotating part 416 is used to drive the second cone 411 and the rod 7 to rotate circumferentially to cooperate with the welding device 5 to weld the retaining ring 8 and the rod 7.

[0081] Specifically, the collar positioning assembly 41 also includes a rotating part 416. The rotating end 417 of the rotating part 416 is coaxially connected to the thick end of the second cone 411. After the pushing assembly 42 pushes the rod 7 to the second cone 411 and the sleeve 412 and completes the collar positioning, the pushing assembly 42 and the second cone 411 together clamp the rod 3310. After the rotating part 416 is activated, it drives the second cone 411 to rotate. The second cone 411 drives the rod 7 to rotate synchronously through contact with the end of the rod 7. The welding device 5 is provided on one side of the collar positioning assembly 41 and performs circumferential welding on the collar and the rod 7 during the rotation of the rod 7.

[0082] The welding device 5 does not need to move around the rod 7; it only needs to perform welding at a fixed position to form a circumferential weld, which simplifies the welding mechanism and improves the continuity and quality of the weld.

[0083] In one possible implementation, the aforementioned pushing component 42 adopts, as follows: Figures 1 to 3 The structure shown is described in the following document. Figures 1 to 3The pushing assembly 42 includes a second slide rail 421 and a positioning slide 422. The positioning slide 422 is slidably connected to the second slide rail 421. The positioning slide 422 is connected to a receiving cylinder 423 that moves along the axis parallel to the rod 7. The receiving cylinder 423 has a circumferential rotational degree of freedom. The end of the rod 7 near the receiving cylinder 423 is used to insert into the receiving cylinder 423. The receiving cylinder 423 moves towards the collar positioning assembly 41 by means of the sliding pushing rod 7 of the positioning slide 422, so as to form a clamping of the rod 7 with the collar positioning assembly 41. The positioning slide 422 is connected to a flat top member 425 that moves along the axis parallel to the rod 7 to push the receiving cylinder 423. The pushing top of the flat top member 425 is rotatably connected to the receiving cylinder 423.

[0084] Specifically, when the rod 7 reaches the welding station, the positioning slide 422 first moves along the second slide rail 421 towards the collar positioning assembly 41, causing the receiving cylinder 423 to gradually approach the end of the rod 7 and insert the end of the rod 7 into the receiving cylinder 423. Since the end of the rod 7 is usually reduced in diameter, the receiving cylinder 423 can form a relatively stable insert fit at that end. Subsequently, the flat top member 425 moves, continuing to push the receiving cylinder 423 and the rod 7 along the axial direction of the rod 7, causing the entire rod 7 to move towards the collar positioning assembly 41 until the other end of the rod 7 is inserted into the gap 413 between the second cone 411 and the sleeve 412, and the retaining ring 8 abuts against the sleeve 412 at the limiting position. During welding, the rod 7 rotates under the drive of the second cone 411, and the receiving cylinder 423 rotates synchronously with the rod 7 through the rotational connection with the flat top member 425, thereby avoiding rigid friction interference between the end of the rod 7 and the pushing assembly 42.

[0085] By incorporating a rotatable receiving cylinder 423 and a flat-top component 425 rotatably connected to it, stable containment and axial pushing of the end of the rod 7 can be achieved, while also accommodating the circumferential rotation of the rod 7 during welding. This avoids the slippage, wear, or jamming problems that occur with traditional rigid push rods during welding rotation. This structure is beneficial for improving the positioning accuracy of the retaining ring 8 and the operational stability of the welding station.

[0086] In a preferred embodiment, the flat top component 425 may be a cylinder, hydraulic cylinder or electric cylinder structure, and its push end is rotatably connected to the receiving cylinder 423 through a rotating shaft or bearing connector, so as to take into account both axial thrust transmission and rotational freedom.

[0087] In some embodiments, see Figure 1 , Figure 2 and Figure 5The positioning slide 422 is connected to a vertical top member 428. The lower end of the vertical top member 428 has a vertical degree of freedom of movement. The lower end of the vertical top member 428 is connected to two sets of grippers 429 that cooperate to form a clamping state or a disengaged state. When the two sets of grippers 429 are in the clamping state, they are used to clamp the end of the rod 3310 so that the receiving cylinder 423 moves away from the rod 7 under the drive of the flat top member 425 and disengages from the rod 7. When the two sets of grippers 429 switch to the disengaged state and disengage from the rod 7, the vertical top member 428 drives the two sets of grippers 429 to move upward and away from the rod 7 so that the second lifting assembly 26 places the rod 7 on the conveying mechanism 21 and moves it to the next working position.

[0088] Specifically, the positioning slide 422 is also equipped with a vertical top member 428, the lower end of which can be raised and lowered vertically, and its lower end is connected to two sets of cooperating jaws 429. The two sets of jaws 429 can switch between a clamping state and a disengaged state. After welding is completed, one end of the rod 7 is still inserted in the receiving cylinder 423. If the receiving cylinder 423 is withdrawn directly, the rod 7 may shift due to loss of support. Therefore, the two sets of jaws 429 first switch to the clamping state, clamping the end of the rod 3310 from both sides, forming temporary stable support for the rod 7. Then, the positioning slide 422 moves in the direction that causes the rod 7 to disengage from the collar positioning assembly 41, and then the flat top member 425 retracts, causing the receiving cylinder 423 to move away from the rod 7, so that the receiving cylinder 423 exits from the end of the rod 7. During the withdrawal of the receiving cylinder 423, the jaws 429 continue to clamp the rod 3310 to prevent the rod 7 from retreating with the receiving cylinder 423.

[0089] After the receiving cylinder 423 is completely detached from the rod 7, the two sets of grippers 429 switch to the separated state and detach from the rod 7. Subsequently, the vertical top member 428 rises, driving the two sets of grippers 429 to move upward and away from the rod 7, making room for the conveying mechanism 21 to continue conveying the rod 7 to the next work station. The second lifting assembly 26 lowers the rod 7 onto the conveying mechanism 21.

[0090] By setting up a liftable vertical top component 428 and two sets of grippers 429, the end of the rod 3310 can be stabilized after welding, and then the receiving cylinder 423 can be safely withdrawn, avoiding instability, falling or displacement of the rod 7 after welding.

[0091] In a preferred embodiment, the gripper 429 may adopt an arc-shaped inner surface clamping structure to better match the outer periphery of the rod 7; the vertical top member 428 may adopt a cylinder, electric cylinder or hydraulic cylinder to provide sufficient lifting stroke and support force.

[0092] In one possible implementation, the aforementioned upper ring correction device 31 employs, as shown in... Figures 1 to 3 The structure shown is described in the following document. Figures 1 to 3When the ring device 3 is an upper ring correction device 31, the upper ring correction device 31 includes a housing 3120, a conveying assembly 3130 and a ring taking assembly 3140. The housing 3120 has an upper ring sleeve 3121 extending horizontally on one side. The conveying assembly 3130 is located on the top of the housing 3120 and extends along the central axis of the upper ring sleeve 3121. The ring taking assembly 3140 is rotatably connected to the discharge end of the conveying assembly 3130. The ring taking assembly 3140 has a picking member 3145 and is used to pick up the retaining ring 8 on the conveying assembly 3130 and then swing it vertically downward to send the retaining ring 8 into the upper ring sleeve 3121.

[0093] Specifically, when the ring-fitting device 3 is the upper ring alignment device 31, the housing 3120 supports the upper ring sleeve 3121, the conveying assembly 3130, and the ring-taking assembly 3140. After the retaining ring 8 is conveyed to the discharge end by the conveying assembly 3130, the ring-taking assembly 3140 rotates to the ring-taking position, and the picking member 3145 clamps the retaining ring 8 located at the discharge end of the conveying assembly 3130. Then, the ring-taking assembly 3140 swings vertically downwards around its rotational connection position, sending the retaining ring 8 from the discharge end of the conveying assembly 3130 into the upper ring sleeve 3121. The rod 7 is inserted axially into the upper ring sleeve 3121 at the ring-fitting station, passing through the retaining ring 8 inside the upper ring sleeve 3121, thereby completing the fitting of the retaining ring 8.

[0094] During the process of the retaining ring 8 entering the upper ring sleeve 3121 from the conveying component 3130, it is actively constrained by the picking component 3145, which avoids the rolling, jamming and attitude deviation caused by the free sliding of the retaining ring 8, so that the retaining ring 8 can enter the upper ring sleeve 3121 in a stable attitude.

[0095] Furthermore, a vibrating feeder 3190 is provided on one side of the feed end of the conveying assembly 3130. The vibrating feeder 3190 is a standard vibrating plate, and its discharge track 3191 is a stainless steel chute that extends obliquely downward to above the feed end of the conveying assembly 3130, allowing the retaining ring 8 to roll or slide onto the conveying assembly 3130 by gravity. An automatic feeding assembly 3193 is provided on one side of the vibrating feeder 3190 for feeding the vibrating feeder 3190.

[0096] In a preferred embodiment, the ring-taking assembly 3140 may include a swing arm 3141 and a drive mechanism 3143. A pickup element 3145 is disposed at the end of the swing arm 3141, and the drive mechanism 3143 controls the swing arm 3141 to reciprocate between a ring-taking position and a ring-feeding position. The inner diameter of the upper ring sleeve 3121 and the outer diameter of the retaining ring 8 maintain a proper fit to ensure that the retaining ring 8 remains stable after entering the upper ring sleeve 3121.

[0097] The drive mechanism 3143 is disposed on one side of the transmission assembly 3130 and extends along the axial direction of the upper ring 3121 toward the swing arm 3141; an eccentric block 3144 is fixed on one side of the swing arm 3141 and is rotatably connected to the extension end of the drive mechanism 3143 for driving the swing arm 3141 to swing.

[0098] In some embodiments, see Figure 1 , Figure 2 and Figure 5 A rotating component 3150 is rotatably connected to the housing 3120, extending axially through the upper ring 3121. One end of the rotating component 3150 located inside the upper ring 3121 is provided with an adsorption component 3151. The lower part of the upper ring 3121 is provided with a through-hole 31211, and the housing 3120 is provided with an alignment detection component 3122 facing the through-hole 31211. A sliding component 3152 extends axially through the rotating component 3150, and the housing 3120 is provided with a collar detection component 3153 located at the end of the moving path of the sliding component 3152.

[0099] Specifically, a rotating component 3150 is provided on the housing 3120. One end of the rotating component 3150 extends into the upper ring sleeve 3121 and is equipped with an adsorption component 3151. After the retaining ring 8 enters the upper ring sleeve 3121, the adsorption component 3151 holds the retaining ring 8, and the rotating component 3150 drives the retaining ring 8 to rotate. A notch 31211 is provided at the lower part of the upper ring sleeve 3121, and the alignment detection component 3122 faces the notch 31211. When the notch of the retaining ring 8 rotates to align with the notch 31211, the alignment detection component 3122 outputs an alignment signal. When the rod 7 inserts into the retaining ring 8 and continues to move forward, the end of the rod 7 pushes against the sliding component 3152. The sliding component 3152 moves to the ring detection component 3153 and triggers the ring detection component 3153, and the system determines that the ring is complete.

[0100] The rotating component 3150 and the alignment detection component 3122 can correct the direction of the notch of the retaining ring 8 to ensure that the notch of the retaining ring 8 and the tube gap of the rod 7 maintain a predetermined angle; the sliding component 3152 and the collar detection component 3153 can confirm the insertion depth of the rod 7 and the collar position status to avoid missing collars and incomplete collars.

[0101] In a preferred embodiment, the alignment detection element 3122 can be a photoelectric detection method, and the collar detection element 3153 can be a limit switch or a proximity switch. The sliding element 3152 can be initially reset by the elastic element 3154 so that it automatically returns to the standby position after one rod 7 has completed the collaring. The rotating element 3150 is rotated by the power supply element 3160.

[0102] A power supply component 3160 is provided on one side of the housing 3120. The power supply component 3160 includes a rotary drive component 3161, two pulleys 3162, and a transmission belt 3163. The rotary drive component 3161 is located on one side of the housing 3120 and has a drive shaft 31611 extending parallel to the axis of the rotary component 3150. One of the two pulleys 3162 is fixedly sleeved on the outer periphery of the drive shaft 31611, and the other is fixedly sleeved on the outer periphery of the rotary component 3150. The transmission belt 3163 is wound around the outer periphery of the two pulleys 3162.

[0103] In one possible implementation, the aforementioned automatic ring-punching device 32 employs, as follows: Figures 41 to 47 The structure shown is described in the following document. Figures 41 to 47 When the ring-forming device 3 is an automatic ring-punching device 32, the automatic ring-punching device 32 includes a frame 3210, a wire feeding assembly 3220, a hook forming assembly 3240, a cutting and bending assembly 3250, a lower arc mold 3260, and an upper arc mold 3270; one side of the frame 3210 is provided with an insertion sleeve 3211 for the steel wire 321 to pass through, and the wire feeding assembly 3220 is located on the side of the frame 3210 near the insertion sleeve 3211; the hook forming assembly 3240 is rotatably connected to the frame 3210 and has a swing hook 3241 that can swing to below the steel wire 321; the cutting and bending assembly 3250 is slidably connected to the frame 3210 in the vertical direction. When 3250 descends, it is used to cut steel wire 321 and press the cut steel wire 321 down onto the swing hook 3241 to form an inverted U-shaped material; the lower arc mold 3260 is located at the lower part of the frame 3210 and below the hook forming assembly 3240, and the upper arc mold 3270 is slidably connected to the frame 3210 in the vertical direction and located above the hook forming assembly 3240; the hook forming assembly 3240 can be detached from the inverted U-shaped material after it is formed, so as to avoid the upper arc mold 3270 pushing the inverted U-shaped material into the lower arc mold 3260, so that the upper arc mold 3270 and the lower arc mold 3260 cooperate to squeeze the inverted U-shaped material on the outer circumference of the rod 7 to form a ring.

[0104] Specifically, when the ring-forming device 3 is an automatic ring-punching device 32, the steel wire 321 is fed into the frame 3210 by the wire feeding assembly 3220 through the insertion sleeve 3211. The hook forming assembly 3240 is pre-swung to the working position, so that the swing hook 3241 is located below the steel wire 321. When the cutting and bending assembly 3250 slides down along the frame 3210, it first cuts the steel wire 321, and then continues to press down on the cut steel wire 321 segment. The middle of the steel wire 321 segment is supported by the swing hook 3241, and both ends are bent downward under the pressing action of the cutting and bending assembly 3250 to form an inverted U-shaped material with the opening facing downward. After the inverted U-shaped material is formed, the hook forming assembly 3240 swings outward, so that the swing hook 3241 disengages from the inverted U-shaped material. Subsequently, the upper arc mold 3270 continues to descend, pushing the inverted U-shaped material into the lower arc mold 3260, and pressing it together with the lower arc mold 3260, causing the inverted U-shaped material to transform into a ring around the outer periphery of the rod 7.

[0105] The steel wire 321 can be formed into a ring on the outer periphery of the rod 7 without the need for a separate prefabricated retaining ring 8; the hook forming component 3240 first participates in the forming of the inverted U-shaped raw material, and then swings outward in time to avoid the swing hook 3241 interfering with the subsequent mold closing and ring forming; the cooperation of the upper and lower arc molds 3260 can improve the consistency of ring forming.

[0106] In a preferred embodiment, the wire feeding assembly 3220 may employ a roller wire feeding or a servo wire feeding mechanism to ensure a stable supply of steel wire 321.

[0107] In some embodiments, see Figures 41 to 47The cutting and bending assembly 3250 has a guide table 3251 extending vertically on the side near the hook forming assembly 3240. The hook forming assembly 3240 slides with the guide table 3251. The frame 3210 has a horizontally extending mounting shaft 3242, and a torsion spring 3243 is sleeved on the mounting shaft 3242, with its two ends connecting the frame 3210 and the hook forming assembly 3240 respectively. When the cutting and bending assembly 3250 moves downward and the guide table 3251 keeps the swing hook 3241 below the wire 321, the cutting and bending assembly 3250 bends the wire 321 onto the swing hook 3241 to form an inverted U-shaped material. When the cutting and bending assembly 3250 continues to move downward until the hook forming assembly 3240 disengages from the guide table 3251, the torsion spring 3243 drives the hook to form. The component 3240 swings outward, causing the swing hook 3241 to disengage from the inverted U-shaped material; the bottom surface of the upper arc mold 3270 is provided with an upwardly arched first arc groove 3273; the bottom surface of the cutting and bending component 3250 has two extension arms 3253 located on both sides of the first arc groove 3273 and extending downward; the adjacent side walls of the two extension arms 3253 are provided with a first forming groove 3254 extending in the vertical direction; the bottom surface of the extension arms 3253 is provided with a second forming groove 3255 communicating with the first forming groove 3254; the two first forming grooves 3254 and the first arc groove 3273 form an inverted U-shaped groove; the top surface of the lower arc mold 3260 is provided with a downwardly concave second arc groove 3262; the first arc groove 3273 and the second arc groove 3262 are used for mold closing and extruding the inverted U-shaped material into a ring.

[0108] Specifically, a guide platform 3251 is provided on the side of the cutting and bending assembly 3250 near the hook forming assembly 3240. When the cutting and bending assembly 3250 initially descends, the guide platform 3251 slides with the hook forming assembly 3240, keeping the swing hook 3241 below the wire 321. When the cutting and bending assembly 3250 descends to a predetermined position, the hook forming assembly 3240 disengages from the guide platform 3251, and the torsion spring 3243 on the mounting shaft 3242 releases its elastic force, causing the hook forming assembly 3240 to swing outward, thus disengaging the swing hook 3241 from the inverted U-shaped material. The two extended arms 3253 at the bottom of the cutting and bending assembly 3250, together with the first arc-shaped groove 3273 at the bottom of the upper arc mold 3270, define the inverted U-shaped groove. The inverted U-shaped material is held in a stable posture along the first forming groove 3254 and the second forming groove 3255. When the upper arc mold 3270 moves downward, the first arc groove 3273 and the second arc groove 3262 of the lower arc mold 3260 close together, causing the inverted U-shaped material to gradually bend and wrap around the outer periphery of the rod 7 to form a ring.

[0109] The guide table 3251 controls the timing of the swing hook 3241's participation in forming and exiting avoidance, and the torsion spring 3243 provides external swing force without the need for additional driving components; the first forming groove 3254, the second forming groove 3255, the first arc groove 3273 and the second arc groove 3262 together guide and constrain the steel wire 321, reduce the deviation of the steel wire 321, and improve the roundness of the ring and the forming stability.

[0110] Furthermore, the lower part of the frame 3210 is provided with a limiting platform 3261 for abutting and cooperating with the bottom of the cutting and bending assembly 3250, and the lower arc mold 3260 is embedded in the top of the limiting platform 3261; the upper arc mold 3270 is provided with an inner sliding cavity 3271 horizontally penetrating through it, and the upper part of the cutting and bending assembly 3250 is provided with a hook boss 3252 protruding into the inner sliding cavity 3271. The hook boss 3252 is hung on the inner bottom wall of the inner sliding cavity 3271, and a top block 3272 for abutting and cooperating with the top of the cutting and bending assembly 3250 is rotatably connected in the inner sliding cavity 3271. The bottom surface height of the cutting and bending assembly 3250 is lower than the bottom surface height of the upper arc mold 3270. When the upper arc mold 3270 moves downward, the upper arc mold 3270 cuts and presses down the steel wire 321 by pushing down the cutting and bending assembly 3250 through the top block 3272; when the cutting and bending assembly 3250 abuts against the limiting table 3261, the top block 3272 swings outward and pops out, the upper arc mold 3270 moves downward relative to the cutting and bending assembly 3250, and pushes the inverted U-shaped material in the cutting and bending assembly 3250 into the lower arc mold 3260.

[0111] Furthermore, the top of the frame 3210 is provided with a downwardly extending first telescopic member 3290, the lower end of which is connected to the top of the upper arc mold 3270. The limiting platform 3261 is slidably connected to the frame 3210 in the vertical direction, and the bottom of the frame 3210 is provided with an upwardly extending second telescopic member 3291, with the limiting platform 3261 located at the upper end of the second telescopic member 3291.

[0112] Furthermore, the frame 3210 is provided with a positioning post 3280 located between the lower arc mold 3260 and the upper arc mold 3270. The positioning post 3280 extends horizontally forward and is arranged perpendicular to the axial direction of the insert sleeve 3211, and is used to be inserted into the rod body 7.

[0113] In one possible implementation, the aforementioned feeding device 33 employs, as shown in the example below. Figures 33 to 40 The structure shown is described in the following document. Figures 33 to 40When the collar device 3 is a feeding device 33, the feeding device 33 includes a mounting base 331, a collar rod 332, a pusher 333, a first drive assembly 334, and a receiving member 335. The collar rod 332 is horizontally arranged and one end in the length direction is the first end 33202. The collar rod 332 is used to sleeve multiple retaining rings 8. The pusher 333 can move along the length direction of the collar rod 332. The first drive assembly 334 is used to drive the pusher 333 to push the retaining ring 8 towards the first end 33202. The receiving member 335 is fixed on the mounting base 331 and has a receiving groove 3351 with the slot facing upward. The receiving groove 3351 is located below the collar rod 332 and is used to receive the retaining ring 8 falling from the first end 33202.

[0114] Specifically, when the collar device 3 is a feeding device 33, multiple retaining rings 8 are pre-fitted onto the collar rod 332. The first driving assembly 334 drives the pushing member 333 to move along the collar rod 332, and the pushing member 333 pushes the multiple retaining rings 8 sequentially toward the first end 33202 of the collar rod 332. When the foremost retaining ring 8 disengages from the first end 33202 of the collar rod 332, the retaining ring 8 falls into the receiving groove 3351 of the receiving member 335. The receiving groove 3351 limits the retaining ring 8, keeping it in a position where the rod body 7 can be inserted. The rod body 7 passes axially through the retaining ring 8 in the receiving groove 3351, thereby completing the fitting of the retaining rings 8.

[0115] Multiple retaining rings 8 can be pre-installed on the collar rod 332, and the pusher 333 supplies the rings in sequence, avoiding manual placement of rings one by one each time, improving ring supply efficiency, and the structure is simple and easy to maintain.

[0116] In a preferred embodiment, the first drive assembly 334 may employ a rodless cylinder, electric cylinder, or push rod mechanism to cause the pusher 333 to be pushed rhythmically on the collar rod 332. The receiving groove 3351 may be designed as an arc-shaped or semi-enclosed structure adapted to the shape of the retaining ring 8 to improve the receiving stability of the retaining ring 8.

[0117] In some embodiments, see Figures 33 to 40 The side wall of the collar rod 332 has a radially outward protruding limiting part 33201, which extends along the length of the collar rod 332 and is used to pass into the slot of the retaining ring 8. The feeding device 33 also includes a position sensor 33120 and a positioning rod 33110. The positioning rod 33110 is slidably inserted in the receiving member 335 and is triggered by the position sensor 33120 when it is pushed by the rod 7 of the retaining ring 8 passing through the receiving groove 3351.

[0118] Specifically, a limiting part 33201 is provided on the side wall of the collar rod 332. When the retaining ring 8 is fitted onto the collar rod 332, the limiting part 33201 passes into the opening of the retaining ring 8, preventing the retaining ring 8 from rotating freely around the collar rod 332. After the rod body 7 passes through the retaining ring 8 in the receiving groove 3351, it continues to push the positioning rod 33110. When the positioning rod 33110 triggers the position sensor 33120, the system determines that the rod body 7 has been inserted into the preset position and stops axial movement.

[0119] The limiting part 33201 can keep the opening direction of multiple retaining rings 8 consistent, which is convenient to form a predetermined relative direction with the tube seam of the rod body 7; the positioning rod 33110 and the position sensor 33120 can detect the insertion position of the rod body 7, thereby improving the stability of the collar position.

[0120] In a preferred embodiment, the positioning lever 33110 may have a reset elastic structure, allowing it to automatically return to its initial position after the lever 7 is removed. The position sensor 33120 may employ a proximity switch or limit switch structure to achieve stable triggering.

[0121] Furthermore, the feeding device 33 also includes a stop member 336 and a second drive assembly 337. The stop member 336 is located on the side facing the first end 33202. The stop member 336 is slidably connected to the mounting base 331 in the vertical direction. The stop member 336 has a first opening 3361 extending downward through the length of the collar rod 332. The end of the first opening 3361 near the first end 33202 has a circumferentially outward protruding cavity 3362. The second drive assembly 337 is used to drive the stop member 336 to slide, so that the stop member 336 has a first working position and a second working position located below the first working position. When the stop member 336 is in the first working position, when the retaining ring 8 on the collar rod 332 disengages from the first end 33202, the retaining ring 8 can enter the protruding cavity 3362.

[0122] Furthermore, the feeding device 33 also includes a magnetic block 338. The magnetic block 338 is fixedly connected to the stop member 336, and the magnetic block 338 can attract the retaining ring 8 that enters the protruding cavity 3362. When the stop member 336 is in the second working position, the retaining ring 8 attracted by the magnetic block 338 can enter the receiving groove 3351.

[0123] Furthermore, the side wall of the collar rod 332 has a radially outward protruding limiting part 33201, which extends along the length direction of the collar rod 332 and is used to insert into the slot of the retaining ring 8.

[0124] Furthermore, the pusher 333 is provided with a sleeve hole 33301 and a second opening 33302 communicating with the sleeve hole 33301. When the pusher 333 moves, the pusher 333 can be sleeved on the outside of the collar rod 332 through the sleeve hole 33301 so that the limiting part 33201 can be inserted into the second opening 33302.

[0125] Furthermore, the collar rod 332 is divided into two parts along its length, including a first section 3321 and a second section 3322. The limiting part 33201 located on the first section 3321 is fixed to the receiving member 335. The feeding device 33 also includes a power cylinder 339 and a clamping rod 3310. The cylinder body of the power cylinder 339 is fixed to the mounting base 331, and the telescopic rod 152 of the power cylinder 339 can extend and retract along the length of the collar rod 332. The clamping rod 3310 is fixedly connected to the telescopic rod 152 of the power cylinder 339. The clamping rod 3310 is parallel to the collar rod 332, and one end of the clamping rod 3310 slides through the second section 3322, so that the clamping rod 3310 can cooperate with the first section 3321 to clamp the second section 3322.

[0126] Furthermore, the first segment 3321 has a plug-in portion 33211, which slides through the second segment 3322 along the length of the collar rod 332.

[0127] Furthermore, the feeding device 33 also includes a position sensor 33120 and a positioning rod 33110. The position sensor 33120 is located on the side of the receiving member 335 opposite to the receiving groove 3351 and is fixedly connected to the receiving member 335. The positioning rod 33110 is parallel to the collar rod 332 and is located between the receiving groove 3351 and the position sensor 33120. The positioning rod 33110 slides through the receiving member 335. When the positioning rod 33110 is pushed and slid by the rod 7 of the retaining ring 8 passing through the receiving groove 3351, the positioning rod 33110 can trigger the position sensor 33120.

[0128] Furthermore, the positioning rod 33110 has a trigger section and a pushing section protruding outward along the circumference of the trigger section, with the pushing section facing the receiving groove 3351. The feeding device 33 also includes a return spring 33130 and a limiting member 33140. The return spring 33130 is located inside the receiving member 335 and sleeved outside the trigger section, so that the return spring 33130 can push the pushing section towards the receiving groove 3351. The limiting member 33140 is fixedly connected to the positioning rod 33110 and is located between the position sensor 33120 and the receiving member 335.

[0129] Furthermore, the feeding device 33 also includes an open-end finger-clamping cylinder 33150 and two guide members 33160. The cylinder body of the open-end finger-clamping cylinder 33150 is fixedly connected to the mounting base 331. The two guide members 33160 are located on the side of the stop member 336 away from the first end 33202. The two guide members 33160 are respectively fixedly connected to the two output ends of the open-end finger-clamping cylinder 33150 so that the two guide members 33160 can be engaged or disengaged. When the two guide members 33160 are engaged, the two guide members 33160 form a guide hole for the rod body 7 to slide through.

[0130] This invention also provides a process for processing using a slotted anchor bolt processing system, comprising the following steps: S1, Step feeding of rod 7: The step moving plate 12 intermittently pushes the rod 7 to move up the step fixed plate 11 step by step. After the rod 7 reaches the top step of the step fixed plate 11, the weighing sensor 14 weighs the rod 7. S2, Rod 7 diversion: Based on the weighing signal of the weighing sensor 14, it is determined whether the rod 7 is qualified. The qualified rod 7 enters the conveying mechanism 21 through the feeding plate 13, and the unqualified rod 7 enters the unqualified area through the discharging plate 13. S3. First rod 7 pipe gap adjustment: After the first rod 7 falls onto the conveying mechanism 21 and is conveyed to the pipe gap adjustment station, the first lifting component 25 grabs the first rod 7 at the pipe gap adjustment station, and the pipe gap adjustment component 22 adjusts the pipe gap of the first rod 7. S4. The first rod 7 is moved to the collar station and the diameter reduction station: After the pipe seam of the first rod 7 is adjusted, the first lifting component 25 grabs the first rod 7 and moves it with the sliding frame 24 to the collar station and the diameter reduction station. The collar device 3 collars one end of the first rod 7, and the positioning diameter reduction component 27 reduces the diameter of the other end of the first rod 7. S5. The second rod 7 is adjusted and handed over to the first rod 7: The first lifting assembly 25 releases the first rod 7 and returns to the pipe gap adjustment position with the sliding frame 24 to grab the second rod 7. The second lifting assembly 26 grabs the first rod 7. The first lifting assembly 25 cooperates with the pipe gap adjustment assembly 22 to adjust the pipe gap of the second rod 7 and make the first rod 7 complete the collar and diameter reduction. S6. Synchronous step-by-step transfer: After the second rod 7 pipe seam adjustment is completed and the first rod 7 is circumcised and reduced in diameter, the first lifting assembly 25 and the second lifting assembly 26 move synchronously with the sliding frame 24. The first lifting assembly 25 transfers the second rod 7 to the circumcised station and the reduced in diameter station, and the second lifting assembly 26 transfers the first rod 7 to the welding station. S7. Synchronous processing: The second rod 7 is simultaneously fitted with a ring and reduced in diameter at the ring-closing station and the diameter-reducing station. At the welding station, the first rod 7 is pushed by the push assembly 42 to move towards the ring-closing positioning assembly 41, so that the retaining ring 8 on the first rod 7 is positioned in a preset position, and the retaining ring 8 is welded to the first rod 7 by the welding device 5. S8. Finished product conveying and palletizing: After the first rod 7 completes all the processing steps, the second lifting component 26 releases the first rod 7, causing the first rod 7 to fall onto the conveying mechanism 21, and the conveying mechanism 21 conveys the first rod 7 to the palletizing equipment 6. S9. Cyclic processing: After steps S7 and S8 are completed, the first lifting assembly 25 and the second lifting assembly 26 return synchronously with the sliding frame 24. The first lifting assembly 25 returns to the pipe seam adjustment station to grab the next rod 7. The second lifting assembly 26 grabs the rod 7 located at the collar station and the diameter reduction station and has completed the collar and diameter reduction, and repeats steps S6 to S9.

[0131] Specifically, in step S1, the stepped moving plate 12 operates intermittently, pushing the rod 7 upwards along the stepped fixed plate 11 step by step. After the rod 7 reaches the top step of the stepped fixed plate 11, it stops at the weighing position and is weighed by the weighing sensor 14.

[0132] In step S2, the controller determines whether the rod 7 is qualified based on the weighing signal. Qualified rods 7 enter the conveying mechanism 21 via the discharge plate 13; unqualified rods 7 enter the unqualified area after the discharge plate 13 changes direction.

[0133] In step S3, after the first rod 7 falls onto the conveying mechanism 21, it is conveyed to the pipe gap adjustment station. The first lifting assembly 25 rises and grabs the first rod 7, and the pipe gap adjustment assembly 22 clamps the rod 7 from both ends and drives the rod 7 to rotate, so that its pipe gap is turned to the preset direction.

[0134] In step S4, after the first rod 7 completes the pipe gap adjustment, the first lifting assembly 25 moves with the sliding frame 24, sending the first rod 7 to the collar station and the diameter reduction station. The collar device 3 completes the collaring at one end, and the positioning and diameter reduction assembly 27 completes the diameter reduction at the other end.

[0135] In step S5, the first lifting assembly 25 releases the first rod 7 and returns to the pipe gap adjustment position to grab the second rod 7, and the second lifting assembly 26 takes over grabbing the first rod 7. While the second rod 7 is adjusting the pipe gap, the first rod 7 completes the collar and diameter reduction.

[0136] In step S6, when the pipe seam adjustment of the second rod 7 is completed and the first rod 7 is clasped and reduced in diameter, the first lifting assembly 25 and the second lifting assembly 26 move synchronously, respectively sending the second rod 7 to the clasp and diameter reduction station and the first rod 7 to the welding station.

[0137] In step S7, the second rod 7 is fitted with a collar and reduced in diameter at the collar station and the diameter reduction station. The first rod 7 is pushed towards the collar positioning assembly 41 by the pusher assembly 42 at the welding station, so that the retaining ring 8 is positioned in the preset position, and then the welding device 5 completes the welding.

[0138] In step S8, after the first rod 7 completes all the processes, the second lifting assembly 26 releases the first rod 7, and the first rod 7 falls back to the conveying mechanism 21, which then transports it to the palletizing equipment 6.

[0139] In step S9, the first lifting assembly 25 and the second lifting assembly 26 return synchronously. The first lifting assembly 25 continues to grab the next rod 7, and the second lifting assembly 26 grabs the rod 7 that has completed the collar reduction. The subsequent steps are repeated.

[0140] The beneficial effects of this process are as follows: through the alternating gripping and synchronous movement of the first lifting component 25 and the second lifting component 26, the preceding and following processes form a continuous cycle, and the pipe gap adjustment, collar diameter reduction, welding positioning and finished product conveying can be connected in parallel, reducing waiting time and improving processing efficiency.

[0141] In one possible implementation, in steps S1 to S2, the telescopic rod 152 of the stop rod assembly 15 extends and blocks the rod body 7 from stopping at the top step of the stepped plate 11. After the weighing sensor 14 obtains the weighing signal, the controller determines whether the weight of the rod body 7 is within the preset weight threshold range. If it is within the preset weight threshold range, the telescopic rod 152 retracts and the discharge plate 13 remains in the feeding state. If it exceeds the preset weight threshold range, the pusher 16 drives the discharge plate 13 to rotate to the discharge state.

[0142] Specifically, in steps S1 to S2, the telescopic rod 152 of the stop rod assembly 15 first extends out of the stop rod 7, so that the rod 7 is stably stopped at the weighing position on the top step. After the weighing sensor 14 completes the weighing, the controller determines whether the weight of the rod 7 is within the preset weight threshold range. If it is qualified, the telescopic rod 152 retracts, and the discharge plate 13 remains in the feeding state; if it is unqualified, the pusher 16 drives the discharge plate 13 to rotate to the discharge state.

[0143] The beneficial effects of this process step are: the mechanical stop bar 7 before weighing can improve the weighing accuracy; and the automatic diversion after weighing can prevent abnormal materials from entering the main processing line.

[0144] In one possible implementation, during the pipe gap adjustment process, after the rod 7 reaches the limiting member 211, the first lifting assembly 25 rises and is surrounded by the clamping member 252; the first electrically controlled slide 2222 drives the rotary table 2223 to approach along the axial direction of the rod 7, the first cone 2224 of the rotary table 2223 abuts against the end of the rod 7 and pushes the rod 7 toward the rotating disk 2213 of the elastic limiting mechanism 221, and the rotary table 2223 drives the rod 7 to rotate to the preset position of the pipe gap.

[0145] Specifically, during the pipe gap adjustment process, after the limit sensor 212 confirms that the rod 7 is in place, the first lifting assembly 25 rises and is surrounded by the clamping member 252. The first electrically controlled slide 2222 drives the rotary table 2223 to approach the rod 7, and the first cone 2224 abuts against the end of the rod 7 and pushes the rod 7 towards the rotating disk 2213. After the rotation sensor 2214 confirms that the rod 7 is in contact with the rotating disk 2213, the rotary table 2223 starts and drives the rod 7 to rotate to the preset position of the pipe gap.

[0146] The beneficial effects of this process step are as follows: by confirming that the rod 7 is in place and clamped in place by the sensor before rotating, it is possible to avoid idling and malfunction; the first cone 2224 and the rotating disk 2213 work together to stably drive the rod 7 to adjust the direction of the pipe seam.

[0147] In one possible implementation, in step S7, the positioning slide 422 moves along the second slide rail 421 toward the collar positioning assembly 41, causing the end of the rod 7 to be inserted into the receiving cylinder 423; the flat top member 425 continues to push the receiving cylinder 423 and the rod 7 toward the collar positioning assembly 41, causing the end of the rod 7 to be inserted into the gap 413 between the second cone 411 and the sleeve 412, and the retaining ring 8 is limited by the sleeve 412 in the collar positioning assembly 41 to a preset position in the axial direction of the rod 7 on the side of the sleeve 412 near the rod 7; the rotating part 416 drives the second cone 411 and the rod 7 to rotate. The welding device 5 rotates circumferentially to perform circumferential welding on the retaining ring 8 and the rod 7. After welding, the two sets of grippers 429 switch to the clamping state to clamp the end of the rod 3310. The positioning slide 422 moves away from the collar positioning assembly 41, causing the rod 7 to disengage from the second cone 411. The flat top 425 retracts, causing the receiving cylinder 423 to disengage from the rod 7. Then, when the two sets of grippers 429 switch to the separation state and disengage from the rod 7, the vertical top 428 drives the two sets of grippers 429 to move upward and away from the rod 7. The second lifting assembly 26 then places the rod 7 on the conveying mechanism 21 and moves it to the next work station.

[0148] Specifically, after the second lifting assembly 26 delivers the completed collar and reduced-diameter rod 7 to the welding station, the positioning slide 422 moves along the second slide rail 421 towards the collar positioning assembly 41, causing the end of the rod 7 to insert into the receiving cylinder 423. Subsequently, the flat top member 425 continues to push the receiving cylinder 423 and the rod 7, causing the other end of the rod 7 to insert into the gap 413 between the second cone 411 and the sleeve 412, and finally causing the retaining ring 8 to abut against the limiting side of the sleeve 412, thereby completing the axial positioning. Afterwards, the rotating part 416 drives the second cone 411 and the rod 7 to rotate synchronously, and the welding device 5 performs circumferential welding on the retaining ring 8 and the rod 7 in a fixed position. After welding, the two sets of grippers 429 switch to the clamping state and clamp the end of the rod 3310; the positioning slide 422 moves away from the collar positioning assembly 41, so that the rod 7 is disengaged from the second cone 411; the flat top 425 retracts, driving the receiving cylinder 423 to disengage from the rod 7; then the grippers 429 separate and are moved upward by the vertical top 428 to avoid it, and the second lifting assembly 26 places the rod 7 on the conveying mechanism 21 and sends it to the next work station or stacking station.

[0149] This step integrates the positioning of the retaining ring 8, the rotary welding, the post-weld detachment, and the return conveying mechanism 21 into a continuous action, which helps to reduce manual intervention and repetitive positioning at the welding station, and improves the automatic connection capability of the welding station and the overall stability of the production line.

[0150] In one possible implementation, during the ring-fitting process, when the ring-fitting device 3 is the upper ring correction device 31, the conveying component 3130 conveys the retaining ring 8 to the discharge end, the ring-taking component 3140 picks up the retaining ring 8 through the picking member 3145 and vertically swings it into the upper ring sleeve 3121, the rotating member 3150 drives the retaining ring 8 to rotate through the adsorption member 3151, so that the notch of the retaining ring 8 is aligned with the notch 31211 of the upper ring sleeve 3121, the rod 7 inserts into the retaining ring 8 in the upper ring sleeve 3121 and pushes the sliding member 3152 to trigger the ring-fitting detection member 3153 to complete the ring-fitting.

[0151] Specifically, when the collar device 3 is the upper collar alignment device 31, the retaining ring 8 is sent to the ring picking position by the vibrating feeder 3190 and the conveying assembly 3130. The ring picking assembly 3140 picks up the retaining ring 8 with the picking member 3145 and swings it down to send it into the upper collar sleeve 3121. The rotating member 3150 adsorbs the retaining ring 8 and drives it to rotate. After the alignment detection member 3122 confirms that the notch of the retaining ring 8 is aligned with the notch 31211 of the upper collar sleeve 3121, the rod 7 is inserted into the retaining ring 8 and triggers the collar detection member 3153.

[0152] The beneficial effects of this process are that the supply, placement, notch correction, and positioning detection of the retaining ring 8 can all be completed automatically, reducing manual intervention.

[0153] In one possible implementation, during the ring-ringing process, when the ring-ringing device 3 is an automatic ring-punching device 32, the wire feeding assembly 3220 conveys the steel wire 321 to below the cutting and bending assembly 3250. The cutting and bending assembly 3250 descends to cut the steel wire 321 and presses the steel wire 321 down onto the swing hook 3241 to form an inverted U-shaped material. After the hook forming assembly 3240 swings outward to avoid it, the upper arc mold 3270 descends and cooperates with the lower arc mold 3260 to squeeze the inverted U-shaped material into a ring and secure it to the outer periphery of the rod body 7.

[0154] Specifically, when the ring-forming device 3 is an automatic ring-forming device 32, the wire feeding assembly 3220 feeds the steel wire 321 to below the cutting and bending assembly 3250. The cutting and bending assembly 3250 descends to cut the steel wire 321, and with the cooperation of the swing hook 3241, bends the steel wire 321 into an inverted U-shaped material. After the hook forming assembly 3240 swings outward and retracts, the upper arc mold 3270 descends and cooperates with the lower arc mold 3260 to compress the inverted U-shaped material into a ring and secure it to the outer circumference of the rod body 7.

[0155] The beneficial effects of this process are that the cutting of steel wire 321, the inverted U-shaped forming and the mold closing to form a ring are completed continuously, which is suitable for on-site automatic ring forming production and reduces the feeding links of the prefabricated retaining ring 8.

[0156] In one possible implementation, during the ring-jointing process, when the ring-jointing device 3 is a feeding device 33, the first driving component 334 drives the pushing component 333 to move along the ring-jointing rod 332 and push multiple retaining rings 8 towards the first end 33202, so that the retaining rings 8 fall sequentially from the first end 33202 into the receiving groove 3351 of the receiving component 335; the rod body 7 passes through the retaining rings 8 in the receiving groove 3351 and pushes the positioning rod 33110. After the positioning rod 33110 triggers the position sensor 33120, it stops the axial movement of the rod body 7, thereby placing the retaining rings 8 in the preset position of the rod body 7.

[0157] Specifically, when the collar device 3 is a feeding device 33, the first driving component 334 drives the pusher 333 to push the retaining ring 8 along the collar rod 332, so that the retaining ring 8 falls into the receiving groove 3351 in sequence. After the rod body 7 passes through the retaining ring 8 in the receiving groove 3351, it continues to push the positioning rod 33110. When the positioning rod 33110 triggers the position sensor 33120, the rod body 7 stops axial movement, so that the retaining ring 8 is in the preset position.

[0158] The beneficial effects of this process step are that the retaining ring 8 can be supplied continuously in sequence, and the insertion position of the rod 7 is confirmed by the position sensor 33120, which can improve the consistency of the collar position.

[0159] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
