Description

Technical Field

[0001] This invention relates to the field of welding and cutting technology, specifically to a dual-station steel ring welding and cutting device with a slag removal structure. Background Technology

[0002] In the production of wheel rims, the steel plates after blanking are generally rolled and shaped into rounds. The rounded steel rim then undergoes double-sided cutting and butt welding on the surfaces to be welded. After double-cutting and butt welding, the rim is butt-welded using a flash butt welding machine, resulting in a complete circular steel rim. After butt welding, the circular steel rim needs to be cleaned with a slag scraper to remove excess metal protruding above the rim from the inner and outer weld seams, ensuring a smooth and flat surface.

[0003] In the current production process, steel rims for wheels are typically manufactured by first cutting raw steel plates using shearing machines, cutting machines, bending machines, and other mechanical equipment. After rolling, the steel rims are usually directly butted together on a flash butt welding machine. Afterward, the workpiece is removed and the weld slag is manually removed. During these processes, manual handling can prevent the rolled steel rims from achieving proper alignment, correction, and roundness. This can lead to misalignment of the rim edges during welding, resulting in substandard quality. Furthermore, removing the steel rims for cleaning during slag removal creates discontinuous operations for welding the next rim, making it impossible to achieve high-efficiency production. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-station steel ring welding and cutting device with a slag removal structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dual-station steel ring welding and cutting device with a slag removal structure, comprising a base, wherein a butt welding machine for welding steel rings is vertically mounted on one side of the base;

[0006] The machine base is provided with two sets of shaping mechanisms for clamping steel rings. A transverse movement mechanism is provided on the side of the machine base near the welding machine to push and pull the shaping mechanism laterally along the machine base, so that one set of shaping mechanisms clamping the steel rings moves to one end of the machine base and the other set of shaping mechanisms clamping the steel rings moves to the front of the welding machine.

[0007] The transverse mechanism includes two guide seats that slide along the track on the top surface of the machine base, and the shaping mechanism includes a tray that is rotatably connected to the guide seats and has pads fixed on its front side. The shaping mechanism is equipped with a straightening component that tightens the outer periphery of the expanded diameter steel ring.

[0008] The base is also provided with a flipping mechanism that reciprocates the swinging of the shaping mechanism that moves to the front of the welding machine, so as to flip the tray at ° and set it parallel to the vertical welding machine, which can drive the pad on the surface of the tray and the welding machine to press the side of the steel ring flush.

[0009] The machine base is symmetrically equipped with slag removal mechanisms at both ends to remove slag from the weld seams of the steel rings. The two slag removal mechanisms are used to remove slag from the weld seams of the steel rings that move alternately to both ends of the machine base.

[0010] Preferably, a threaded rod is connected to the base via a bearing seat, and the threaded rod is threadedly driven by the guide seat. A servo motor that drives the threaded rod to rotate is installed at one end of the base.

[0011] The butt welding machine is equipped with two vertically parallel clamping cylinders and jaws. One clamping cylinder and jaws are mounted on the butt welding machine, while the other clamping cylinder and jaws slide horizontally on the butt welding machine and are pushed and pulled by the upsetting cylinder on the butt welding machine.

[0012] The bottom output end of the clamping cylinder is connected to an electrode pressure block, and a splash guard installed on the front side of the welding machine is located directly above the center of the machine base.

[0013] Preferably, the surface of the tray has multiple straight slots through it, and an expanding roller slides in the straight slots. A back plate is installed on the back of the tray, and a turntable with oblique slots on its surface is rotated in the middle of the back plate for sliding and pushing the expanding roller.

[0014] Preferably, a gear plate is installed on one side of the turntable, a motor is installed on the surface of the back plate, and the output end of the motor is connected to a drive gear that meshes with the gear plate.

[0015] Preferably, the edge of the front of the tray is provided with an arc-shaped groove, the orthopedic component includes a sliding frame that slides along the arc-shaped groove, and a hydraulic rod for pushing and pulling the sliding frame is hinged to the back plate.

[0016] Preferably, a linkage frame is movably connected to the middle of the sliding frame. The linkage frame consists of three continuously hinged links of equal length and a reinforcing strip hinged in the middle of the two end links. The three links of equal length form a parallelogram structure through the reinforcing strip. One end of the two end links extending out of the reinforcing strip is connected to a straightening roller.

[0017] Preferably, one end of the connecting rod away from the straightening roller is movably connected to a rotating column, and the other end of the connecting rod away from the straightening roller is equipped with a fan-shaped plate. A limit opening is provided on the surface of the fan-shaped plate, and a movable seat passing through the limit opening is connected to the end of the reinforcing strip near the fan-shaped plate. A rotating pin that is threaded to the middle of the rotating column is movably connected to one end of the movable seat.

[0018] Preferably, a support block is vertically mounted on the back of the tray, and a groove is provided on the upper edge of the base away from the welding machine to restrict the end of the support block, and a notch is provided in the middle of the groove to allow the end of the support block to exit.

[0019] The flipping mechanism includes a hydraulic rod 2 that moves in the base. The surface of the base has a through hole for the hydraulic rod 2 to rotate. One side of the through hole is pulled by a tension spring. The back of the tray is also symmetrically equipped with a card seat.

[0020] Preferably, the slag removal mechanism includes lifting columns installed at both ends of the base, with an indexing plate connected to the top output end of the lifting column, a slider installed at the output end of the indexing plate, a horizontal plate sliding on the top of the slider, and a slag cutting rod and a polishing machine respectively provided at both ends of the horizontal plate.

[0021] Preferably, there are two slag cutting rods and two polishing machines, and the surfaces of the two slag cutting rods that are close to each other are provided with cutting blades. A cylinder for pushing and pulling the slider is installed on the side of the horizontal plate, and a screw module for driving the two polishing machines to move towards each other is installed on the horizontal plate.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: The dual-station steel ring welding and cutting device with a slag removal structure achieves synchronous shaping of the steel ring inside and outside by expanding rollers that move from the inside out and straightening rollers that move along the circumference, preventing local deformation during the rolling process. Then, the steel ring held by the two shaping mechanisms is moved back and forth to the welding machine by a transverse mechanism. The shaping mechanism is then pushed by a flipping mechanism to align the steel ring with the welding position for flush correction. Finally, the slag removal mechanism performs slag removal and polishing on the steel ring that moves horizontally alternately to both ends of the machine base. This ensures that the welding and cutting device can simultaneously achieve the alignment, correction and rounding after the initial rolling when performing dual-station positioning welding and slag removal on the steel ring, which facilitates the improvement of the efficiency and quality of wheel steel ring processing.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-4The present invention provides a technical solution: a dual-station steel ring welding and cutting device with a slag removal structure, including a base 1, a butt welding machine 2 for welding steel rings is vertically installed on one side of the base 1, two sets of shaping mechanisms 3 for clamping steel rings are provided on the base 1, and a transverse movement mechanism is provided on the side of the base 1 near the butt welding machine 2 for pushing and pulling the shaping mechanism 3 laterally along the base 1, so that one set of shaping mechanisms 3 for clamping steel rings moves to one end of the base 1, and the other set of shaping mechanisms 3 for clamping steel rings moves to the front side of the butt welding machine 2;

[0036] The transverse mechanism includes two guide seats 101 that slide along the track on the top surface of the base 1. A threaded rod 102 is connected to the base 1 through a bearing seat, and the threaded rod 102 is threadedly driven to the guide seats 101. A servo motor 103 that drives the threaded rod 102 to rotate is installed at one end of the base 1.

[0037] The butt welding machine 2 is equipped with two vertically parallel clamping cylinders 201 and jaws 203. One clamping cylinder 201 and jaws 203 are mounted on the butt welding machine 2, while the other clamping cylinder 201 and jaws 203 slide horizontally on the butt welding machine 2 and are pushed and pulled by the upsetting cylinder a on the butt welding machine 2. The bottom output end of the clamping cylinder 201 is connected to the electrode pressure block 202. A splash guard is installed on the front side of the butt welding machine 2, which is located directly above the center of the machine base 1. The splash guard is used to block the sparks generated during the welding of the steel ring and prevent the sparks from splashing everywhere and causing hidden dangers.

[0038] In this embodiment, the servo motor 103 is started to drive the threaded rod 102 to rotate in the two guide seats 101, so that the two guide seats 101 move along the track on the top surface of the machine base 1. When one of the guide seats 101 drives the shaping mechanism 3 to move to the front of the welding machine 2, the other guide seat 101 will drive the shaping mechanism 3 to move to one end of the machine base 1, so that the two shaping mechanisms 3 can perform dual-station conveying of the two steel rings along the transverse mechanism.

[0039] When the steel ring moves onto the welding machine 2, the clamping cylinder 201 pushes the electrode block 202 downward, which enables the electrode block 202 and the jaws 203 to press the joined steel ring together. When the power is on, the welding current heats and melts the end of the steel ring. Then, the upsetting cylinder a applies upsetting pressure to drive one set of electrode blocks 202 and jaws 203 to move laterally, so that the two ends of the steel ring are squeezed together until they are welded into a whole. This is the prior art. For reference, please refer to Chinese Patent No. CN206689601U, which discloses a flash butt welding machine for welding steel rings.

[0040] Please see Figures 1-3 , Figures 5-8The shaping mechanism 3 includes a tray 301 rotatably connected to the guide seat 101 and with a pad fixed on its front. The surface of the tray 301 has multiple straight slots, and an expanding roller 302 slides in the straight slots. A back plate 304 is installed on the back of the tray 301. A turntable 303 with a slanted slot on its surface is rotatably mounted in the middle of the back plate 304 for sliding and pushing the expanding roller 302. A gear plate 305 is installed on one side of the turntable 303. A motor 306 is installed on the surface of the back plate 304. The output end of the motor 306 is connected to a drive gear that meshes with the gear plate 305. The pad on the front of the tray 301 is made of chromium-copper alloy.

[0041] In this embodiment, the motor 306 is used to drive the drive gear to mesh with the gear disk 305. The gear disk 305 can drive the turntable 303 to rotate in both directions. Thus, the turntable 303 can slide and push the expansion roller 302 through the inclined groove on its surface. This allows the expansion roller 302 to slide along the straight groove on the surface of the tray 301, thereby facilitating the movement of the expansion roller 302 towards or away from the center of the tray 301.

[0042] When the rolled steel ring is placed on the tray 301, the expanding roller 302, which moves outside the center of the tray 301, can spread the steel ring at an equal angle, so that the rolled steel ring can be evenly fitted and expanded.

[0043] Please see Figures 1-3 , Figures 5-8 The front edge of the tray 301 is provided with an arc groove 3011. The shaping mechanism 3 is provided with a straightening component 4 for tightening the outer periphery of the expanded steel ring. The straightening component 4 includes a slide frame 401 that slides along the arc groove 3011. A hydraulic rod 402 for pushing and pulling the slide frame 401 is hinged on the back plate 304.

[0044] In this embodiment, when the rolled steel ring is placed on the tray 301 and the expanding roller 302, which is spread open at equal angles, pushes the sliding frame 401 through two hydraulic rods 402, so that the two sliding frames 401 slide against each other along the arc groove 3011. This allows the two sets of orthopedic components 4 to squeeze and tighten the outer periphery of the steel ring, and to gradually press it from the position away from the end of the steel ring towards the end position, so that the weld gap is small and the two ends of the steel ring can be prevented from loosening when they are connected to the electrode pressure block 202 and the jaw 203 for welding.

[0045] Please see Figures 5-9 The middle of the sliding frame 401 is movably connected to the linkage frame 403. The linkage frame 403 is composed of three continuously hinged equal-length linkages and a reinforcing strip hinged in the middle of the two end linkages. The three equal-length linkages form a parallelogram structure through the reinforcing strip. One end of the two end linkages that extends out of the reinforcing strip is connected to the orthopedic roller 404.

[0046] One end of the connecting rod away from the straightening roller 404 is movably connected to a rotating column 405, and the other end of the connecting rod away from the straightening roller 404 is equipped with a sector plate 406. A limit opening is provided on the surface of the sector plate 406. A movable seat 407 passing through the limit opening is connected to the end of the reinforcing bar near the sector plate 406. A rotating pin 408 that is threaded to the middle of the rotating column 405 is movably connected to one end of the movable seat 407.

[0047] In this embodiment, by rotating the rotating pin 408 and the rotating column 405 through threaded transmission, the end of the rotating pin 408 and the movable seat 407 can be rotated. The rotating pin 408 rotating in the forward direction can gradually increase the distance between the rotating column 405 and the movable seat 407, and the rotating pin 408 rotating in the reverse direction can gradually decrease the distance between the rotating column 405 and the movable seat 407.

[0048] When the rotating pin 408 is rotated in both directions, the parallelogram-shaped linkage frame 403 will cause the three equal-length linkages and the reinforcing strip to rotate. As a result, the linkages on both ends will cause the straightening roller 404 to adjust the distance between itself and the outer wall of the steel ring. When the straightening component 4 drives the straightening roller 404 to press against the steel ring at a constant distance, the moving slide frame 401 can drive the two parallel straightening rollers 404 to perform stable rolling support and straightening on the outer wall of the steel ring. By using the expanding roller 302 that moves from the inside to the outside and the straightening roller 404 that moves along the circumference, the steel ring that has been expanded and rolled can be simultaneously shaped inside and outside, preventing deformation in local positions during the conventional rolling process and ensuring that the steel ring can be rounded twice during welding and shaping.

[0049] When the hydraulic rod 402 pulls the slide frame 401 to reset, the slide frame 401 can drive the straightening component 4 away from the weld position. After the expansion roller 302 retracts, the clamped steel ring can be quickly released, making it convenient for workers to pick up and put down.

[0050] Please see Figures 1-3 and Figure 8 A support block 3012 is vertically mounted on the back of the tray 301. The upper edge of the base 1 away from the welding machine 2 is provided with a channel 104 to restrict the end of the support block 3012. A notch is provided in the middle of the channel 104 for the end of the support block 3012 to exit. When the tray 301 moves horizontally along the base 1, the tray 301 will slide along the channel 104 through the end of the support block 3012 on the back. Thus, when the tray 301 moves to both ends of the base 1 for slag removal, it can be easily supported horizontally. When the end of the support block 3012 on the back of the tray 301 moves along the channel 104 to the notch position, it is convenient for the tray 301 to rotate in the forward direction to drive the support block 3012 to disengage from the notch in the middle of the channel 104. Conversely, it is also convenient for the tray 301 to rotate in the reverse direction to drive the support block 3012 to re-insert into the notch.

[0051] The base 1 is also equipped with a flipping mechanism that reciprocates the swinging of the shaping mechanism 3 that moves to the front of the welding machine 2. The flipping mechanism includes a hydraulic rod 5 that moves in the base 1. The surface of the base 1 is provided with a through hole for the hydraulic rod 5 to rotate. One side of the through hole is pulled by a tension spring 501. The back of the tray 301 is also symmetrically equipped with a card seat 502. The hydraulic rod 5 can be pulled by the tension spring 501 to abut against one side of the inner wall of the through hole, ensuring that the extended output end of the hydraulic rod 5 can be inserted into the card seat 502 to achieve locking.

[0052] In this embodiment, when the transverse mechanism drives the two sets of shaping mechanisms 3 to transport the clamped steel ring to the center position of the machine base 1, the output end is pushed upward by the extension of the hydraulic rod 2 5, so that the output end of the hydraulic rod 2 5 can be inserted into the card seat 502 on the back of the tray 301. Then, the hydraulic rod 2 5 is activated to push the card seat 502, so that the tray 301 rotates 90° around the guide seat 101, and the weld seam of the closed steel ring end is sent between the electrode pressure block 202 and the jaw 203. The 90° rotated tray 301 is set parallel to the vertical welding machine 2, which can drive the pad on the surface of the tray 301 and the welding machine 2 to perform flush correction on the side of the steel ring, so that the side edge of the welded steel ring can be guaranteed to have good flatness. Finally, by rotating the steel ring 90°, the steel ring to be welded can be smoothly fed without the need for secondary positioning of the fed steel ring.

[0053] Since the welding machine 2 is located in the center of the base 1, when the threaded rod 102 drives the two sets of guide seats 101 to move alternately to the front position of the welding machine 2, it is convenient for the two sets of shaping mechanisms 3 to perform alternating loading and unloading of the steel ring in two positions.

[0054] Conversely, when the hydraulic rod 25 is tightened to retract and pull the output end downward, the output end of the hydraulic rod 25 gradually pulls the card seat 502. Then, the hydraulic rod 25 is continued to retract, causing the tray 301 to rotate around the guide seat 101 until it is placed horizontally. When the tray 301 is placed horizontally, the output end of the hydraulic rod 25 is tightened again, which can disengage the output end of the hydraulic rod 25 from the card seat 502. At this time, it is convenient for the transverse movement mechanism to drive the two sets of guide seats 101 and the shaping mechanism 3 to achieve reciprocating transverse movement.

[0055] It is necessary to explain that when the output end of the hydraulic rod 2 5 is engaged inside the card holder 502, the servo motor 103 will not drive the threaded rod 102 to move the two sets of guide seats 101 in both directions.

[0056] Please see Figures 1-3 and Figure 10The base 1 is symmetrically provided with a slag removal mechanism 6 for cutting slag from the steel ring weld. The slag removal mechanism 6 includes a lifting column 601 installed at both ends of the base 1. The top output end of the lifting column 601 is connected to an indexing plate 602. The output end of the indexing plate 602 is equipped with a slider 603. The top of the slider 603 is slidably connected to a horizontal plate 604. The two ends of the horizontal plate 604 are respectively provided with a slag cutting rod 605 and a polishing machine 606.

[0057] There are two slag cutting rods 605 and two polishing machines 606, and the surfaces of the two slag cutting rods 605, which are close to each other, are equipped with cutting blades. A cylinder 607 for pushing and pulling the slider 603 is installed on the side of the horizontal plate 604. A screw module 608 for driving the two polishing machines 606 to move towards each other is installed on the horizontal plate 604. The screw of the screw module 608 adopts a double thread. By using the screw module 608 to drive the two polishing machines 606 to move towards each other, it is convenient to adjust the distance between the two polishing machines 606, and thus adjust the gap between the polishing wheel and the steel ring weld.

[0058] In this embodiment, when the welded steel ring moves alternately to both ends of the machine base 1 along with the horizontal tray 301, the lifting column 601 of the slag removal mechanism 6 drives the horizontal plate 604 to move downward, thereby using the cutters on the surfaces of the two slag cutting rods 605 to longitudinally remove the weld residue inside and outside the steel ring, ensuring that larger and protruding weld slag can be quickly removed.

[0059] After the lifting column 601 is activated and drives the slag cutting rod 605 to rise, the indexing plate 602 drives the slider 603 to complete a 180° horizontal rotation, which enables the two polishing machines 606 to align with the weld position of the steel ring after slag cutting. Then, by using the lifting column 601 to pull the horizontal plate 604, the two downward-moving polishing machines 606 drive the polishing wheel to polish and grind the surface of the weld at the slag cutting position, making the surface of the steel ring after slag cutting smoother. Through the two sets of slag removal mechanisms 6, the steel ring that has been alternately moved to both ends of the machine base 1 and completed welding can be slag cut in a dual-station alternating manner.

[0060] It should be noted that: by moving and adjusting the horizontal plate 604 along the slider 603 via the cylinder 607, the position of the slag cutting rod 605 and the polishing machine 606 can be adjusted. When processing steel rings of different diameters, the slag cutting rod 605 and the polishing machine 606 can be easily switched to perform surface grinding treatment on the weld seam of the steel ring.

[0061] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
