Description

Technical Field

[0001] This utility model relates to the field of pipe bending processing, and in particular to a bending device for foot brake pipe bending processing. Background Technology

[0002] The foot brake bend tube of an electric tricycle is a crucial component of the entire braking system. It transmits the force exerted by the driver pressing the foot brake pedal to the braking system through leverage, ultimately slowing down or stopping the vehicle. It typically includes the bend tube body, the foot brake pedal (often with anti-slip design), and mounting holes or connecting ends for connecting to other brake levers or cables. The bend tube device is the core component used in the production of foot brake bend tubes.

[0003] For example, patent document CN221602908U discloses a round pipe bending device for processing foot brake pipes of tricycles. The processing platform has a feeding arc-punching die in the middle of its processing center. One end of the feeding arc-punching die is equipped with a steel pipe conveying cylinder, and the other end is equipped with a bending mechanism. A steel pipe guide groove is provided between the feeding arc-punching die and the bending mechanism. The lever of the steel pipe conveying cylinder is configured to correspond to the blank slot. A pair of steel pipe wheels are pre-installed between the bending wheel frames on one side of the bending mechanism. The steel pipe blank is positioned in the blank clamping slot, with a groove corresponding to the steel pipe wheel groove. A transmission gear is installed in the bending mechanism, and a bending cylinder is installed at one end of the bending mechanism. A transmission rack is installed between the lever end of the bending cylinder and the transmission gear. The steel pipe blank is fed into the feeding slot of the feeding arc punching die and positioned in the blank clamping slot. The bending cylinder drives the bending stationary wheel and bending pressure wheel to rotate and bend the steel pipe blank into a foot brake bend. The bending force is uniform, avoiding flattening and cracking of the bent blank, and reducing the production cost of the enterprise.

[0004] In existing technologies, most steel pipe blanks are placed on bending devices manually. Manual feeding not only places a heavy workload on workers but also has low efficiency and cannot adapt to the current trend of production automation. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-7As shown, a bending device for processing foot brake pipes includes a support frame, a pushing mechanism on the support frame, a pipe pushing block 205, a clamping mechanism on the front side of the support frame, a bending mechanism on the front side of the support frame, and a feeding mechanism above the pushing mechanism. The feeding mechanism includes a storage bin 301, a feeding roller 302 rotatably connected to the lower end bearing of the storage bin 301, an arc-shaped groove on the side of the feeding roller 302 matching the pipe bending material, a guide groove shaft 303 fixedly connected to the rear side of the feeding roller 302, a spiral guide groove on the guide groove shaft 303 with a rotation angle of 90 degrees, two symmetrically arranged fixing rods 304 welded to the rear side of the storage bin 301, a feeding linkage push block 305 slidably connected to the fixing rods 304, the feeding linkage push block 305 slidably connected to the spiral guide groove on the guide groove shaft 303, and the feeding linkage push block 305 fixed to the fixing rods 304. The tube pusher 205 is connected to the first spring 306 and can abut against the feeding linkage pusher 305. In use, several pre-cut tubes are placed into the storage bin 301. The device pushes the tubes to the middle of the clamping mechanism and the bending mechanism through the tube pusher 205, and then performs the bending operation. During the backward movement of the tube pusher 205, it abuts against the feeding linkage pusher 305, and the feeding linkage pusher 305 is forced to move. During this process, the first spring 306 is compressed, and the feeding linkage pusher 305 drives the feeding roller 302 to rotate 90 degrees through the spiral guide groove on the fixed rod 304. Thus, the feeding roller 302 can transfer the tubes in the arc-shaped groove to the feeding slide 102. Then the tube pusher 205 moves, and the feeding linkage pusher 305 resets under the action of the first spring 306. Thus, the feeding roller 302 resets, and the tubes in the storage bin 301 fall into the arc-shaped groove of the feeding roller 302 under the action of gravity.

[0029] The support frame includes a workbench 101, a feeding slide 102 fixedly connected to the top of the workbench 101, a storage bin 301 fixedly connected to the top of the workbench 101, the bottom of the feeding slide 102 is set as an arc surface, which matches the diameter of the pipe, a through groove runs through the middle of the feeding slide 102, and the pipe push block 205 is slidably connected to the through groove in the middle of the feeding slide 102. A clamping platform 103 is fixedly connected to the front side of the workbench 101, and a bending extension frame 104 is fixedly connected to the front side of the clamping platform 103. In use, the feeding slide 102 conveys the pipe, the clamping platform 103 is used to support the clamping mechanism, and the bending extension frame 104 is used to carry the bending mechanism.

[0030] The feeding mechanism also includes a horizontal lead screw 203 rotatably connected to the bottom center of the workbench 101 by a bearing. Side slide rods 202 are bolted to both sides of the bottom of the workbench 101. A movable frame 204 is threaded onto the horizontal lead screw 203. The two ends of the movable frame 204 are slidably connected to the side slide rods 202. A first motor 201 is bolted to the rear side of the workbench 101. The output end of the first motor 201 is fixedly connected to the horizontal lead screw 203. In use, the first motor 201 drives the horizontal lead screw 203 to rotate. The horizontal lead screw 203 drives the movable frame 204 to move through the thread. The movable frame 204 drives the tube pusher block 205 to move. The tube pusher block 205 can push the tube to move on the feeding slide 102.

[0031] The clamping mechanism includes a horizontal slide bar 406 bolted to the clamping platform 103. Two symmetrically arranged sliders 404 are slidably connected to the horizontal slide bar 406. A clamping wheel 405 is rotatably connected to the top of the sliders 404, and a connecting rod 403 is hinged to the bottom of the sliders 404. A clamping linkage push block 401 is slidably connected to the side slide bar 202. The other ends of the two connecting rods 403 are hinged to the front of the clamping linkage push block 401. A second spring is fixedly connected between the clamping linkage push block 401 and the side slide bar 202. Spring 402 and movable frame 204 can abut against clamping linkage push block 401. When in use, when movable frame 204 moves to the front, movable frame 204 abuts against clamping linkage push block 401, clamping linkage push block 401 is forced to move. During this process, second spring 402 is compressed, clamping linkage push block 401 pushes connecting rod 403 to make slider 404 move closer to the center. Then the two sliders 404 drive two clamping wheels 405 to clamp in the center. Clamping wheels 405 clamp the pipe to ensure smooth bending process.

[0032] The bending mechanism includes a rotating shaft 504 rotatably connected to a bending extension frame 104. A bending fixed wheel 505 is fixedly connected to the top of the rotating shaft 504. A rotating arm 506 is fixedly connected to the rotating shaft 504. A bending moving wheel 507 is rotatably connected to the top of the rotating arm 506. A worm gear 503 is fixedly connected to the lower end of the rotating shaft 504. A worm 502 is rotatably connected to the lower front side of the worktable 101. The worm 502 meshes with the worm gear 503. A second motor 501 is fixedly connected to the front side of the worktable 101. The output end of the second motor 501 is fixedly connected to the worm 502. In use, the second motor 501 drives the worm 502 to rotate. The worm 502 drives the worm gear 503 to rotate. The worm gear 503 drives the rotating shaft 504 to rotate. The rotating shaft 504 drives the bending fixed wheel 505 and the rotating arm 506 to rotate synchronously. The bending moving wheel 507 abuts against and forces the pipe to bend.

[0033] Working principle: Several pre-cut pipes are placed into the storage hopper 301. The first motor 201 drives the horizontal lead screw 203 to rotate. The horizontal lead screw 203 drives the moving frame 204 to move through the thread. The moving frame 204 drives the pipe pusher block 205 to move. The pipe pusher block 205 can push the pipes to move on the feeding slide 102. During the backward movement of the pipe pusher block 205, it abuts against the feeding linkage pusher block 305, and the feeding linkage pusher block 305 is forced to move. During this process, the first spring 306 is compressed. The feeding linkage pusher block 305 drives the feeding roller 302 to rotate 90 degrees through the spiral guide groove on the fixed rod 304. Thus, the feeding roller 302 can transfer the pipes in the arc-shaped groove into the feeding slide 102. Then the pipe pusher block 205 moves, and the feeding linkage pusher block 305 is reset under the action of the first spring 306. 02 Reset: Under the action of gravity, the pipe in the storage bin 301 falls into the arc-shaped groove of the feeding roller 302. The pipe pusher 205 pushes the pipe between the two clamping wheels 405. When the moving frame 204 moves to the front, the moving frame 204 abuts against the clamping linkage pusher 401, and the clamping linkage pusher 401 is forced to move. During this process, the second spring 402 is compressed, and the clamping linkage pusher 401 pushes the connecting rod 403 to make the slider 404 move closer to the center. Then, the two sliders 404 drive the two clamping wheels 405 to clamp in the center. The clamping wheels 405 clamp the pipe. The second motor 501 drives the worm 502 to rotate. The worm 502 drives the worm wheel 503 to rotate. The worm wheel 503 drives the rotating shaft 504 to rotate. The rotating shaft 504 drives the bending fixed wheel 505 to rotate synchronously with the rotating arm 506. The bending moving wheel 507 abuts against and forces the pipe to bend.
