Description

Technical Field

[0001] This invention relates to the field of metal wire bending technology, and more specifically, to a continuous conveying multi-station bending and forming equipment and method for metal wire. Background Technology

[0002] Metal wire bending is the mainstream processing technology, suitable for shaping and bending of wires of different materials such as round steel, galvanized iron wire, stainless steel wire, and alloy wire. At present, large-scale mass production mostly adopts continuous conveyor bending equipment to complete multi-station step-by-step bending processing. It relies on multiple sets of correction rollers to radially limit and straighten the wire, ensuring the straightness of the wire conveying, thereby improving the bending dimensional accuracy and adapting to continuous forming production operations on assembly lines.

[0003] Traditional wire bending and forming equipment often adopts a split-type correction structure, with separate vertical and horizontal correction wheel sets for bidirectional straightening and limiting of the wire. The two correction mechanisms are driven and adjusted independently. When adapting to the processing of metal wires of different diameters and adjusting the equipment gap parameters, the operators need to operate the drive components of the vertical and horizontal correction mechanisms separately and adjust the clamping gap of the wheel sets step by step. The debugging process is cumbersome and time-consuming, and the debugging cycle for changing wire specifications is long. It cannot adapt to the current production mode of multi-variety, small-batch, and quick-change in the manufacturing industry. Furthermore, coaxiality is difficult to guarantee during debugging. The split and independent adjustment structure is prone to misalignment of the vertical and horizontal correction centers. During the wire conveying process, it is subjected to asymmetrical lateral extrusion force, which can easily lead to wire deviation, twisting, surface damage, and conveying jamming. This not only causes wire raw material loss but also leads to excessive deviations in bending forming angle and arc length, resulting in poor product consistency. Summary of the Invention

[0012] Furthermore, a traction assembly is installed at the end of the movable frame away from the fixed frame. The traction assembly includes a mounting frame fixedly connected to the movable frame. The mounting frame has two symmetrically installed traction wheels inside. Multiple second moving slots are opened on the inner wall of the mounting frame at positions corresponding to the traction wheels. Moving blocks are slidably installed inside the second moving slots.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 8 A continuous conveying multi-station bending and forming equipment for metal wire includes a workbench 1. Multiple fixed frames 101 and multiple movable frames 102 are installed on the upper end of the workbench 1. A first correction wheel group 2 is installed on the fixed frame 101, and a second correction wheel group 3 is installed on the movable frame 102. The second correction wheel group 3 is arranged perpendicular to the first correction wheel group 2. The first alignment wheel set 2 includes multiple fixed wheels 201 and multiple first movable wheels 202. A first movable rod 203 is slidably installed on the fixed frame 101 at a position corresponding to the first movable wheel 202. The first movable wheel 202 is rotatably connected to the first movable rod 203. A first rotating rod 204 is installed through the first movable rod 203 on the side near the moving frame 102. A first threaded groove 205 is opened on the outer wall of the first rotating rod 204. A second rotating rod 303 is installed through the moving frame 102 on the end near the fixed frame 101. A second threaded groove 304 is opened on the outer wall of the second rotating rod 303. Ball bearings 206 are installed inside both the first threaded groove 205 and the second threaded groove 304. The two ball bearings 206 are connected to the first movable rod 203 and the moving frame 102 respectively. The pitch of the first threaded groove 205 is twice the pitch of the second threaded groove 304. A connecting wheel 207 is fixedly installed at the lower end of both the first rotating rod 204 and the second rotating rod 303. The two connecting wheels 207 mesh and drive each other. The second correction wheel group 3 includes a plurality of second moving wheels 301 mounted on the moving frame 102. Two second moving rods 302 are slidably mounted on the upper end of the moving frame 102 at positions corresponding to the second moving wheels 301. The second moving wheels 301 and the second moving rods 302 are rotatably connected. The movable frame 102 is equipped with an adjustment component 305. The adjustment component 305 includes a first bidirectional lead screw 306 rotatably installed inside the movable frame 102. Gears 307 are fixedly installed at both ends of the first bidirectional lead screw 306. Multiple racks 107 are fixedly installed on the upper end of the worktable 1. Multiple guide rods 105 are installed through the upper end of the movable frame 102. The lower end of the guide rods 105 is fixedly connected to the worktable 1. A threaded rod 106 is installed through one side of the movable frame 102. The threaded rod 106 is rotatably connected to the worktable 1 and threadedly connected to the movable frame 102. The fixed frame 101 has a first sliding groove 103 inside, the first moving rod 203 is slidably connected to the first sliding groove 103, the fixed wheel 201 and the first moving wheel 202 are alternately arranged, the moving frame 102 has two second sliding grooves 104, the second moving rod 302 is slidably connected to the second sliding groove 104, and multiple second moving wheels 301 are alternately arranged, the upper end of the rack 107 passes through the lower end of the moving frame 102 and extends to its upper side, and the rack 107 meshes with the gear 307 for transmission.

[0023] By adopting the above technical solution, in use, firstly, rotating the threaded rod 106 drives the movable frame 102 to move. When the movable frame 102 moves, it can press the second threaded groove 304 on the second rotating rod 303 through the ball bearings 206. At this time, under the action of the decomposed force of the pressing force, it can drive the second rotating rod 303 to rotate. After the second rotating rod 303 rotates, it can drive one of the connecting wheels 207 to rotate. At this time, since the two connecting wheels 207 mesh with each other, the first rotating rod 204 can rotate under the action of the two connecting wheels 207. When the first rotating rod 204 rotates, it can press the ball bearings 206 on the first movable rod 203. At this time, under the action of the decomposed force of the pressing force... The first moving rod 203 can be moved when the moving frame 102 descends by one unit length. Since the pitch of the first threaded groove 205 is twice that of the second threaded groove 304, the first moving rod 203 will descend by two units of length for every unit length the moving frame 102 descends. When the gap between the first moving wheel 202 and the fixed wheel 201 increases, as the moving frame 102 descends, the rack 107 and the gear 307 mesh, causing the first bidirectional lead screw 306 to rotate. The rotation of the first lead screw can drive the two second moving rods 302 to move. When the second moving rods 302 move, they can drive the second moving wheels 301 to move, thereby increasing the gap between the second moving wheels 301. When the gap between the fixed wheel 201 and the first moving wheel 202 increases, and the gap between the two sets of second moving wheels 301 increases, the metal wire to be processed is first passed between the fixed wheel 201 and the first moving wheel 202, and then passed between the two sets of opposite second moving wheels 301. After that, the threaded rod 106 is rotated in the opposite direction, which allows the moving frame 102 to move to the initial position, and at the same time allows the first moving wheel 202 and the second moving wheel 301 to move to the initial position. In this way, the first moving wheel 202 and the fixed wheel 201 can be used to squeeze the metal wire vertically, and the two sets of second moving wheels 301 can be used to squeeze the wire horizontally. Under the action of the first rotating rod 204 and the second rotating rod 303, the positions of the first correction wheel group 2 and the second correction wheel group 3 can be automatically adjusted when adjusting the position of the moving frame 102. When correcting the wire, the center positions of the first correction wheel group 2 and the second correction wheel group 3 are always kept consistent. Furthermore, the simultaneous adjustment of multiple first moving wheels 202 and multiple second moving wheels 301 can keep the squeezing pressure of multiple first moving wheels 202 and multiple second moving wheels 301 on the wire consistent.

[0024] A guide assembly 4 is installed on one side of the upper end of the workbench 1. The guide assembly 4 includes a support frame 401 that is slidably installed on the upper end of the workbench 1. A rotating ring 402 is rotatably installed in the middle of the support frame 401. Two extrusion wheels 403 are symmetrically installed inside the rotating ring 402. Multiple first moving grooves 404 are opened inside the rotating ring 402. The extrusion wheels 403 move along the inside of the first moving grooves 404 and rotate relative to the first moving grooves 404. A top block 405 is slidably installed inside the first moving groove 404. A compression spring 406 is fixedly installed at the end of the top block 405 away from the extrusion wheel 403. The end of the compression spring 406 away from the top block 405 is fixedly connected to the inner wall of the first moving groove 404. A first drive motor 407 is fixedly installed on the upper end of the support frame 401. A drive wheel 408 is fixedly installed on the output end of the first drive motor 407. Multiple drive teeth 409 are opened on the outer wall of the rotating ring 402. The drive wheel 408 meshes with the drive teeth 409. The support frame 401 is fixedly connected to the movable frame 102.

[0025] By adopting the above technical solution, when the metal wire to be processed is passed between the first moving wheel 202 and the fixed wheel 201, the metal wire to be processed is first passed through the two extrusion wheels 403. At this time, the extrusion spring 406 can extrude the top block 405, and the top block 405 can extrude the extrusion wheel 403, so that it clamps the metal wire to be processed. During operation, the first drive motor 407 drives the drive wheel 408 to rotate. When the drive wheel 408 rotates, it meshes with the drive teeth 409 and drives the rotating ring 402 to rotate. When the rotating ring 402 rotates, it drives the extrusion wheel 403 to revolve through the first moving groove 404, so that the extrusion wheel 403 extrudes the metal wire to be processed in different directions, thereby performing preliminary straightening of the metal wire to be processed. When adjusting the moving frame 102, the support frame 401 fixedly connected to the moving frame 102 also moves synchronously, thereby automatically changing the position of the two extrusion wheels 403, so that the center position of the gap between the two extrusion wheels 403 is always aligned with the center position of the gap between the two sets of second moving wheels 301.

[0026] A traction component 5 is installed at the end of the movable frame 102 away from the fixed frame 101. The traction component 5 includes a mounting frame 501 fixedly connected to the movable frame 102. The mounting frame 501 has two traction wheels 502 installed in a symmetrical structure. Multiple second moving slots 503 are opened on the inner wall of the mounting frame 501 at positions corresponding to the traction wheels 502. Moving blocks 504 are slidably installed inside the second moving slots 503. The traction wheels 502 are rotatably connected to the moving blocks 504. A second bidirectional screw 505 is installed through the upper end of the mounting frame 501. The second bidirectional screw 505 is rotatably connected to the mounting frame 501. The two sides of the second bidirectional screw 505 are threadedly connected to two different moving blocks 504, one above and one below. A second drive motor 506 is fixedly installed on the moving block 504 on the side away from the second bidirectional lead screw 505. The output end of the second drive motor 506 is coaxially connected to the traction wheel 502. The second drive motor 506 is used to drive the traction wheel 502 to rotate.

[0027] By adopting the above technical solution, before processing, after the metal wire to be processed is passed between the two sets of second moving wheels 301, the metal wire to be processed is then passed between the two traction wheels 502. After that, the second bidirectional lead screw 505 is rotated, so that the moving block 504 moves inside the second moving groove 503. After the moving block 504 moves, it can drive the traction wheel 502 to move. At this time, the second drive motor 506 can drive the traction wheel 502 to rotate. When the traction wheel 502 rotates, it can cause the metal wire to be processed to move through friction.

[0028] Multiple placement racks 108 are installed on one side of the upper end of the workbench 1. The placement racks 108 are used to place wire feeding reels. Multiple bending heads 109 are installed on the other side of the upper end of the workbench 1. The bending heads 109 are used to bend metal wires.

[0029] By adopting the above technical solution, before use, the wire reel with the metal wire to be processed is placed on the placement rack 108, and then the metal wire to be processed is passed between the two extrusion rollers 403. When the metal wire to be processed passes through the bending head 109, the bending head 109 can bend the metal wire to be processed.

[0030] A continuous conveying multi-station bending method for metal wire includes: S1: Place the wire feeding reel on the workbench 1 placement frame 108, rotate the threaded rod 106 in the forward direction to expand the gap between the first correction wheel group 2 and the second correction wheel group 3, and pass the wire through the guide assembly 4, the two correction wheel groups and the traction wheel 502 in sequence to complete the wire threading and front clamping positioning. S2: Reverse rotation of threaded rod 106 resets moving frame 102, linkage correction wheel group gathers and clamps wire, the equipment automatically ensures that guide component 4 and two sets of correction wheel groups are coaxial and evenly stressed, fine adjustment of second bidirectional screw 505 calibrates the distance of traction wheel 502, start first drive motor 407 to drive extrusion wheel 403 to revolve, perform all-round pre-straightening of wire, and eliminate wire deformation stress; S3: Start the second drive motor 506 to drive the traction wheel 502 to rotate. Rely on friction to convey the metal wire at a uniform speed. During the conveying process, two sets of correction wheels limit the wire in both horizontal and vertical directions. The threaded rod 106 can be finely adjusted to match the wire specifications. It works in conjunction with the guide component 4 to align synchronously and maintain the straightness of the wire conveying throughout the process to avoid slippage and pressure damage. S4: The calibrated wire is conveyed to multiple bending heads 109. The heads complete multi-station segmented bending processing according to preset parameters. The wire can be continuously fed and processed in cycles. To change the wire specifications, only the threaded rod 106 needs to be adjusted to adjust the gap. After the bent wire is discharged, the finished product is collected and the processing process ends.

S2: Reverse rotation of the threaded rod resets the moving frame, and the linkage correction wheel group gathers and clamps the wire. The equipment automatically ensures that the guide component, the two correction wheel groups are coaxial and the force is uniform. The second bidirectional screw is finely adjusted to calibrate the traction wheel spacing. The first drive motor is started to drive the extrusion wheel to revolve, and the wire is pre-straightened in all directions to eliminate the deformation stress of the wire. S3: Start the second drive motor to drive the traction wheel to rotate, and transport the metal wire at a constant speed by relying on friction. During the transportation process, two sets of correction wheels limit the wire in both horizontal and vertical directions. The threaded rod can be finely adjusted to match the wire specifications. It works in conjunction with the guide component to align synchronously and maintain the straightness of the wire transportation throughout the process to avoid slippage and pressure damage. S4: The corrected wire is conveyed to multiple bending heads. The heads complete multi-station segmented bending processing according to preset parameters. The wire can be continuously fed and processed in cycles. To change the wire specifications, only the threaded rod needs to be adjusted to adjust the gap. After the bent wire is discharged, the finished product is collected and the processing process ends.
