Description

Technical Field

[0001] This invention relates to the field of pipe fitting processing equipment, and in particular to a method for integrated processing of double-ended pipe ends. Background Technology

[0002] Currently, when processing pipe ends, one end of the pipe is usually fixed, and the other end is processed using processing equipment such as punching dies. After the processing of that end is completed, the pipe is manually moved and the other unprocessed end of the pipe is processed again.

[0003] However, during the transposition process, errors can easily occur in the two fixed positions of the pipe fitting, which can lead to dimensional errors in the processing of both ends of the pipe fitting. At the same time, transposition and secondary positioning will reduce the efficiency and stability of the overall processing of the pipe fitting. Summary of the Invention

[0004] The purpose of this invention is to provide a method for integral processing of double-ended tube ends to solve the above-mentioned technical problems.

[0005] To solve the above technical problems, the present invention provides a method for integral processing of double-ended tube ends, comprising the following steps:

[0006] Step 1: Load the pipe fittings to the positioning component;

[0007] Step 2: Place the pipe fitting in the V-groove of the positioning component. The positioning cylinder and the detection cylinder are placed on both sides of the pipe fitting, and the length of the pipe fitting is detected by the positioning cylinder and the detection cylinder.

[0008] Step 3: If the pipe length does not meet the pipe length requirement, the pipe is transported to the waste box; if the pipe length meets the pipe length requirement, it is transported to the next process.

[0009] Step 4: When the pipe fitting is transported to the next process, the pipe fitting is gripped by the pneumatic gripper. The transverse seat drives the pneumatic gripper to move the pipe fitting to the composite clamping mechanism and place the pipe fitting in the main clamping mold and the auxiliary clamping mold for clamping and fixing.

[0010] Step 5: The first and second punching mechanisms are placed at both ends of the pipe fitting, and the punches in the first and second punching mechanisms are moved to the positions to be processed.

[0011] Step 6: The die in the first die mechanism holds the end of the pipe fitting, and one or more dies in the second die mechanism process the pipe fitting;

[0012] Step 7: After the die in the second die mechanism finishes processing the pipe end, the die in the second die mechanism holds the pipe end against the pipe end, while one or more dies in the first die mechanism process the other end of the pipe.

[0013] Step 8: Unloading of pipe fittings.

[0014] Furthermore, the composite clamping mechanism includes a main clamping mold and a movable secondary clamping mold located inside the main clamping mold. The secondary clamping mold has a circumferential groove on the side of the main clamping mold where it clamps the pipe. The first punching die mechanism and the second punching die mechanism have the same structure, and each of the first punching die mechanism and the second punching die mechanism is equipped with several punches. After the positioning component positions the pipe, the positioned pipe is transported to the composite clamping mechanism for clamping. One of the punches in the first punching die mechanism abuts against one end of the pipe, and one of the punches in the second punching die mechanism punches the other end of the pipe and pushes the secondary clamping mold to move.

[0015] Furthermore, the first punching mechanism includes a punching base for mounting a plurality of punches and a movable plate disposed at the bottom of the punching base. The punching base and the movable plate are in movable engagement through a feed rail. The bottom of the movable plate is in movable engagement with a shift rail. The feed rail is used to control the punches to move closer to or further away from the pipe fitting, and the shift rail is used to control the switching between the plurality of punches.

[0016] Furthermore, a guide post connects the main clamping mold and the auxiliary clamping mold, and an elastic element is sleeved on the outer periphery of the guide post so that a gap is formed between the main clamping mold and the auxiliary clamping mold through the elastic element. When the auxiliary clamping mold is pushed, the elastic element is compressed and one side of the auxiliary clamping mold fits against the main clamping mold.

[0017] Furthermore, a limiting groove is provided on the side of the secondary clamping mold away from the guide post, and a pressure block is installed on the side of the main clamping mold. When a gap is formed between the secondary clamping mold and the main clamping mold, the pressure block is fastened to the limiting groove.

[0018] Furthermore, the main clamping mold has a dotting hole along the radial direction of the pipe fitting, and the end of the dotting hole faces the annular groove when the auxiliary clamping mold and the main clamping mold are in contact with each other. The dotting punch is movably disposed in the dotting hole.

[0019] Furthermore, the end of the punch furthest from the pipe fitting is connected to the punching cylinder via a transition rod. A guide block is installed on one side of the punching hole, and the side of the punching head fits against the guide block so that the guide block guides the punching head when it punches the pipe fitting.

[0020] Furthermore, a circular groove is provided on the side of the auxiliary clamping die away from the annular groove. When one of the first or second punching die mechanisms squeezes the auxiliary clamping die, the auxiliary clamping die cooperates with the punching die to flare or bulge the end of the pipe fitting.

[0021] Furthermore, the positioning component includes a positioning bracket, an inclined block on the positioning bracket, and a baffle plate on the inclined surface of the inclined block. A V-groove is formed between the baffle plate and the inclined block, and the pipe is placed in the V-groove.

[0022] Furthermore, a positioning cylinder is provided on one side of the V-groove. The extended end of the positioning cylinder abuts against one end of the pipe fitting to position one end of the pipe fitting in a designated position. A detection cylinder is provided on the other side of the V-groove. The extended end of the detection cylinder is used to detect the distance between the other end of the pipe fitting and the detection cylinder.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. The pipe fitting is clamped in the middle by a composite clamping mechanism. With the cooperation of the first and second punching mechanisms on both sides, the pipe fitting can be processed at both ends simultaneously without the need for secondary clamping or repositioning. This avoids errors that may occur during the repositioning process and increases the efficiency of pipe fitting processing.

[0025] 2. The cooperation between the main clamping mold and the auxiliary clamping mold, as well as the ring groove on one side of the auxiliary clamping mold, can effectively extrude the middle section of the pipe fitting, avoiding the problem that the middle section of the pipe fitting cannot be successfully processed in one go due to the clamping of the middle section by the composite clamping mechanism.

[0026] 3. The matching of the punch and the hole allows for the marking of the middle section of the pipe fitting while ensuring stable clamping.

[0027] 4. The positioning components are used to initially position the pipe fittings, which increases the accuracy of the pipe fittings when they are placed in the composite clamping mechanism, thereby increasing the stability and accuracy of pipe end processing. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0052] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0053] like Figure 1-21 The present invention provides a method for integral processing of double-ended tube ends, comprising the following steps:

[0054] Step 1: Load pipe fitting 5 into positioning component 6;

[0055] Step 2: Place the pipe fitting 5 in the V-groove 64 of the positioning component 6. The positioning cylinder 65 and the detection cylinder 66 are placed on both sides of the pipe fitting 5, and the length of the pipe fitting 5 is detected by the positioning cylinder 65 and the detection cylinder 66.

[0056] Step 3: If the length of pipe fitting 5 does not meet the pipe fitting length requirement, pipe fitting 5 is transported to waste box 67. If the length of pipe fitting 5 meets the pipe fitting length requirement, it is transported to the next process.

[0057] Step 4: When the pipe fitting 5 is transported to the next process, the pipe fitting 5 is gripped by the pneumatic gripper 68. The transverse transfer seat 610 drives the pneumatic gripper 68 to move the pipe fitting 5 to the composite clamping mechanism 2, and the pipe fitting 5 is placed in the main clamping mold 21 and the auxiliary clamping mold 22 for clamping and fixing.

[0058] Step 5: The first punching die mechanism 3 and the second punching die mechanism 4 are placed at both ends of the pipe fitting 5, and the punch 31 in the first punching die mechanism 3 and the punch 31 in the second punching die mechanism 4 are moved to the position to be processed respectively.

[0059] Step 6: The die 31 in the first die mechanism 3 holds the end of the pipe 5, and one or more dies 31 in the second die mechanism 4 process the pipe 5.

[0060] Step 7: After the die 31 in the second die mechanism 4 finishes processing the pipe end, the die 31 in the second die mechanism 4 presses against the end of the pipe 5, while one or more dies 31 in the first die mechanism 3 process the other end of the pipe 5.

[0061] Step 8: Unload the pipe fittings.

[0062] In a preferred embodiment of this solution, the first and second punching mechanisms are each equipped with three sets of punches, and the three sets of punches are respectively named the first punch, the second punch, and the third punch. In the processing technology of the above two punching mechanisms with a total of six sets of punches, the pipe fittings are processed according to the following preferred processing flow:

[0063] S1. Pipe fittings loading;

[0064] S2. The positioning component positions the pipe fitting;

[0065] S3. The first die in the first die mechanism holds the end of the pipe fitting, and the first die in the second die mechanism cooperates with the auxiliary clamping die to extrude the middle section of the pipe fitting and widen the pipe end.

[0066] S4. The first die in the first die mechanism does not move, and the second die in the second die mechanism works with the auxiliary clamping die to extrude the pipe end into a slanted drum.

[0067] S5. The second die in the second die mechanism does not move, the second die in the first die mechanism extrudes the tube, and at the same time the punching punch marks the extrusion position in the middle section of the tube.

[0068] S6. The second die in the second die mechanism does not move, and the third die in the first die mechanism performs extrusion shaping on the extrusion position in the previous process, with a shaping radius of R0.3max.

[0069] S7. The third die in the first die mechanism retracts, and the third die in the second die mechanism performs unloading pre-processing on the pipe fitting (unloading pre-processing: the pipe fitting is reshaped to make subsequent unloading smoother).

[0070] S8. Pneumatic gripper unloads and moves pipe fittings.

[0071] This solution employs a dual-end pipe end integrated processing device when using the aforementioned dual-end pipe end integrated processing method. The dual-end pipe end integrated processing device includes a frame 1, a composite clamping mechanism 2 mounted on the frame 1, a first punching mechanism 3 and a second punching mechanism 4 respectively located on both sides of the composite clamping mechanism 2, and a positioning component 6 for positioning the pipe fitting 5. The composite clamping mechanism 2 includes a main clamping mold 21 and a movable secondary clamping mold 22 located inside the main clamping mold 21. The secondary clamping mold 22 clamps the pipe fitting 5 close to the main clamping mold 21. A circumferential groove 23 is provided on one side of the mold 21. The first punching die mechanism 3 and the second punching die mechanism 4 have the same structure, and a plurality of punches 31 are respectively installed on the first punching die mechanism 3 and the second punching die mechanism 4. After the positioning component 6 positions the pipe 5, the positioned pipe 5 is transported to the composite clamping mechanism 2 for clamping. One of the punches 31 in the first punching die mechanism 3 abuts against one end of the pipe 5, and one of the punches 31 in the second punching die mechanism 4 punches the other end of the pipe 5 and pushes the auxiliary clamping mold 22 to move.

[0072] Specifically, the pipe fitting is initially positioned by the positioning component, and then the positioned pipe fitting is transported to the composite clamping mechanism by the pneumatic gripper. The main clamping die and the auxiliary clamping die cooperate to clamp and fix the middle section of the pipe fitting. At this time, the two ends of the pipe fitting face the first punching die mechanism and the second punching die mechanism, respectively. Then, one punch in the first punching die mechanism approaches and abuts against one end of the pipe fitting, while one punch in the second punching die mechanism approaches and performs pipe end processing on the other end of the pipe fitting. Since the end of the pipe fitting is supported by the first punching die mechanism and the middle section of the pipe fitting is clamped and fixed by the main clamping die and the auxiliary clamping die, the punch of the second punching die mechanism is extremely stable when processing the pipe end of the pipe fitting. When it is necessary to process the pipe end of the pipe fitting by the punch in the first punching die mechanism, the punch in the second punching die mechanism supports the pipe fitting and the punch in the first punching die mechanism stamps the pipe end. The punches in the first punching die mechanism and the punches in the second punching die mechanism act as support and stamping parts to ensure stable processing of both ends of the pipe fitting.

[0073] The stamping process performed on the pipe fittings by the die in this solution is the same as the existing stamping method, and will not be described in detail here.

[0074] It is worth mentioning that, since the auxiliary clamping mold can move relative to the main clamping mold, and the side of the auxiliary clamping mold that holds the pipe fitting closer to the main clamping mold has an annular groove, when the punch in the first punching mold mechanism abuts against one end of the pipe fitting, the punch in the second punching mold mechanism approaches and pushes the auxiliary clamping mold to move. Subsequently, after the auxiliary clamping mold and the main clamping mold are in contact, the punch of the punch in the second punching mold mechanism simultaneously punches the pipe end of the pipe fitting, so that the pipe fitting is compressed and extruded. Due to the annular groove structure on one side of the auxiliary clamping mold, and the fact that the other parts of the outer periphery of the pipe fitting are clamped and supported by the main clamping mold, the auxiliary clamping mold, the punch of the first punching mold mechanism, and the punch of the second punching mold mechanism, the annular groove guides the position of the pipe fitting to be extruded, so that the pipe fitting can only bulge out towards the annular groove when extruded, ensuring that the position of the pipe fitting to be extruded is in the middle section of the pipe fitting. Thus, even if the middle section of the pipe fitting is clamped by the main clamping mold and the auxiliary clamping mold, it can still be extruded, increasing the processing effect of the middle section of the pipe fitting.

[0075] The main clamping mold and the auxiliary clamping mold are both composed of two clamping blocks arranged opposite each other. One clamping block of the main clamping mold is connected to one clamping block of the auxiliary clamping mold, and the other clamping block of the main clamping mold is connected to the other clamping block of the auxiliary clamping mold. The main clamping mold controls the clamping and separation of the two clamping blocks through a hydraulic cylinder, thereby controlling the clamping and releasing of the pipe fitting by the main clamping mold and the auxiliary clamping mold. Similarly, the two clamping blocks that make up the auxiliary clamping mold are provided with a semi-annular structure so that after the two clamping blocks clamp each other to form the auxiliary clamping mold, one side of the auxiliary clamping mold has an annular groove structure.

[0076] In particular, the dies installed in the first and second die mechanisms include, but are not limited to, flaring punches, extrusion punches, and chamfering punches, and different dies can be replaced according to the specific processing requirements of the pipe fittings.

[0077] Preferably, the first punching mechanism 3 includes a punching base 32 for mounting a plurality of punches 31 and a movable plate 33 disposed at the bottom of the punching base 32. The punching base 32 and the movable plate 33 are in movable engagement through a feed rail 34. The bottom of the movable plate 33 is in movable engagement with a switching rail 35. The feed rail 34 is used to control the punches 31 to move closer to or away from the pipe fitting 5, and the switching rail 35 is used to control the switching between the plurality of punches 31.

[0078] Specifically, by setting up the feed rail and the shift rail, when it is necessary to switch between several dies installed on the first or second die mechanism, the moving plate is controlled to translate relative to the shift rail by a servo motor and a lead screw drive. This causes the moving plate to switch several dies, so that the required die can be moved to the tube end position. After the designated die is aligned with the tube end, the die is moved along the feed rail by a hydraulic cylinder, so that the die is close to the tube end for processing or away from the tube end for separation.

[0079] Preferably, a guide post 24 is connected between the main clamping mold 21 and the auxiliary clamping mold 22, and an elastic element is sleeved on the outer periphery of the guide post 24 so that a gap is formed between the main clamping mold 21 and the auxiliary clamping mold 22 through the elastic element. When the auxiliary clamping mold 22 is pushed, the elastic element is compressed and one side of the auxiliary clamping mold 22 is in contact with the main clamping mold 21.

[0080] Specifically, the main clamping mold and the auxiliary clamping mold are connected by guide pillars. The auxiliary clamping mold can move along the guide pillars, allowing it to move relative to the main clamping mold. When the main clamping mold and the auxiliary clamping mold are not in use, the auxiliary clamping mold is pushed by the elastic element, creating a gap between the main clamping mold and the auxiliary clamping mold. When the punch pushes the auxiliary clamping mold to move, the elastic element is compressed, causing the auxiliary clamping mold and the main clamping mold to fit together on one side, thereby ensuring that the extrusion position in the middle section of the pipe can be stably guided by the annular groove.

[0081] The elastic element is a compression spring.

[0082] Preferably, a limiting groove 25 is provided on the side of the auxiliary clamping mold 22 away from the guide post 24, and a pressure block 26 is installed on one side of the main clamping mold 21. When a gap is formed between the auxiliary clamping mold 22 and the main clamping mold 21, the pressure block 26 is fastened to the limiting groove 25.

[0083] Specifically, when the main clamping mold and the auxiliary clamping mold are not in use, the auxiliary clamping mold will be reset by the elastic element. In order to ensure that the auxiliary clamping mold will not be removed from the position of the main clamping mold, a limiting groove and a pressure block are set. When the elastic element resets the auxiliary clamping mold, the pressure block will be engaged in the limiting groove and the position of the limiting groove will be limited by the pressure block, thereby limiting the reset position of the auxiliary clamping mold and increasing the stability of the auxiliary clamping mold.

[0084] Preferably, the main clamping mold 21 has a dotting hole 27 along the radial direction of the pipe 5, and the end of the dotting hole 27 faces the annular groove 23 when the auxiliary clamping mold 22 and the main clamping mold 21 are in contact with each other. The dotting punch 28 is movably disposed in the dotting hole 27.

[0085] Specifically, the middle section of the pipe fitting can be extruded through the annular groove. However, some pipe fittings require dotting at the extrusion location. Therefore, this solution sets dotting holes and dotting punches so that after the middle section of the pipe fitting is extruded, the dotting punch moves back and forth along the dotting holes to dotting and punching the middle section of the pipe fitting. Furthermore, since the end of the dotting hole faces the annular groove where the secondary mold and the main mold fit together, the dotting position is accurately matched with the middle section of the pipe fitting.

[0086] Preferably, the end of the dotting punch 28 away from the pipe fitting 5 is connected to the dotting cylinder 210 via a transition rod 29. A guide block 211 is installed on one side of the dotting hole 27, and the side of the dotting punch 28 is in contact with the guide block 211 so that when the dotting punch 28 does dotting on the pipe fitting 5, the guide block 211 guides the dotting punch 28.

[0087] Specifically, when the pipe fitting is marked with a marking punch, the marking cylinder controls the extension and retraction of the transition rod, which in turn drives the marking punch to extend and retract, so that the marking punch can stably mark the pipe fitting under the control of the marking cylinder.

[0088] Meanwhile, due to the guide block, when the punching punch is punching, the guide block will guide the side of the punch, increasing the accuracy of the punching punch on the pipe fitting.

[0089] Preferably, the auxiliary clamping mold 22 has a circular groove 212 on the side away from the annular groove 23. When one of the punches 31 in the first punching mechanism 3 or the second punching mechanism 4 presses the auxiliary clamping mold 22, the auxiliary clamping mold 22 cooperates with the punch 31 to flare or bulge the end of the pipe fitting 5.

[0090] Specifically, some pipe fittings require flaring or extrusion at the pipe end during processing. Therefore, by setting a circular groove, the die in the first or second die mechanism can flare or extrude the pipe fitting at the end of the circular groove after cooperating with the circular groove of the auxiliary clamping die. Since the annular groove has been filled by the extrusion structure in the middle section of the pipe fitting before this processing, when the die compresses and extrudes the pipe fitting, the extrusion position of the pipe fitting will be guided by the circular groove, causing the end of the pipe fitting to flare or extrude towards the circular groove.

[0091] It is worth mentioning that the circular groove and the annular groove can be used to guide the pipe fitting simultaneously or sequentially. When the circular groove and the annular groove guide the pipe fitting sequentially, the annular groove is usually used to guide the pipe fitting first, followed by the circular groove. When the annular groove guides the pipe fitting first, the shape of the die end can be used to fill the position of the circular groove, thereby avoiding the circular groove from affecting the guiding effect of the annular groove. Similarly, when the circular groove and the annular groove guide the pipe fitting simultaneously, the corresponding die is used to cooperate with the circular groove, so that the pipe fitting end and the middle section are processed simultaneously.

[0092] Preferably, the positioning component 6 includes a positioning bracket 61, an inclined block 62 disposed on the positioning bracket 61, and a baffle plate 63 disposed on the inclined surface of the inclined block 62. A V-groove 64 is formed between the baffle plate 63 and the inclined block 62, and the pipe 5 is placed in the V-groove 64.

[0093] Specifically, the pipe is initially placed on the inclined block, and the pipe rolls down the inclined surface of the block and is blocked by the baffle plate, so that the pipe is placed in the V-groove for initial positioning.

[0094] The bottom of the baffle is connected to a cylinder, which controls the raising and lowering of the baffle.

[0095] Preferably, one side of the V-groove 64 has a positioning cylinder 65, the extended end of which abuts against one end of the pipe fitting 5 so that one end of the pipe fitting 5 is in a designated position. The other side of the V-groove 64 has a detection cylinder 66, the extended end of which is used to detect the distance between the other end of the pipe fitting 5 and the detection cylinder 66.

[0096] Specifically, after the pipe is placed in the V-groove, the extended end of the positioning cylinder acts as a positioning support and extends to a predetermined distance. Then, the extended end of the detection cylinder extends outward and pushes against the pipe during the extension process until the other end of the pipe is pushed and abuts against the extended end of the positioning cylinder. At this time, by judging the movement distance of the extended end of the detection cylinder, the length of the pipe can be calculated, and it can be determined whether the length of the pipe meets the current processing requirements of the pipe.

[0097] The detection cylinder uses a "CEP1B20-75L" model cylinder, which can display the displacement distance of the extended end. Then, by combining the displacement distance with the positioning action of the extended end of the positioning cylinder, the length of the pipe fitting can be calculated.

[0098] Preferably, a waste box 67 is installed on one side of the positioning bracket 61. When the length of the pipe exceeds or falls below the required length, the pipe 5 is placed in the waste box 67 by the pneumatic gripper 68.

[0099] Specifically, after detecting the length of the pipe fitting, it is determined whether the length of the pipe fitting meets the requirements. If the length of the pipe fitting does not meet the requirements, the defective product is moved to the waste box for storage by the pneumatic gripper, while qualified products are transferred to the composite clamping mechanism for clamping by the pneumatic gripper.

[0100] It is worth mentioning that the positioning component in this solution also includes a transverse movement mechanism for conveying the pipe fitting. The transverse movement mechanism includes a pneumatic gripper 68 for gripping the pipe fitting and a transverse movement rail 69 located on one side of the pneumatic gripper 68. The pneumatic gripper 68 is in movable engagement with the transverse movement rail 69 through a transverse movement seat 610, so that the transverse movement seat 610 can move along the transverse movement rail 69 through a servo motor and a gear rack transmission method. In turn, the transverse movement seat 610 drives the pneumatic gripper 68 to move laterally, so as to ensure that the pneumatic gripper can carry the pipe fitting to move at various positions such as the positioning component, the composite clamping mechanism, and the discharge position.

[0101] The pneumatic gripper uses an existing pneumatic gripper structure.

[0102] Specifically, the pneumatic gripper 68 is connected to the transverse shifter 610 via a cylinder 611, allowing the cylinder 611 to lift and lower the pneumatic gripper 68. This causes the transverse shifter 610 to move the pneumatic gripper 68 to a designated position. The cylinder 611 then lowers the pneumatic gripper 68, which then grips the pipe fitting 5 and resets it via the cylinder 611. The transverse shifter 610 then moves the pneumatic gripper 68 and the pipe fitting 5 to the next workstation. At this point, the lowering of the cylinder 611 and the release of the pneumatic gripper 68 place the pipe fitting 5 in the designated position, increasing the overall stability and accuracy during pipe fitting transportation.
