A control box is bolted to one outer wall of the worktable, and a rectangular opening is formed on one outer wall of the worktable. A collection box is placed on the bottom inner wall of the rectangular opening. A guide plate is bolted to one inner wall of the worktable, and slide rails are bolted to both sides of the top outer wall of the worktable. A fixing mechanism is slidably connected to the inner walls of both slide rails. The fixing mechanism includes a support base, and an L-shaped fixing plate is bolted to one side of the top outer wall of the support base.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Example: Figure 1-6As shown, this utility model provides a punching device for producing shock absorber steel plates for electric tricycles, including a punching table 1, a mounting frame 11, a hydraulic cylinder 12, a punching head 13, and a punching die 16. The mounting frame 11 and the punching die 16 are fixedly mounted on the upper surface of the punching table 1. The hydraulic cylinder 12 is fixedly mounted on the top of the mounting frame 11, and the punching head 13 is fixedly mounted on the piston end of the hydraulic cylinder 12. The punching head 13 is vertically aligned with the die hole of the punching die 16. During the punching process of the leaf spring, when the leaf spring is above the punching die 16, as the piston end of the hydraulic cylinder 12 extends, the hydraulic cylinder 12 can push the punching head 13 to descend vertically. The punching head 13 punches the leaf spring above the punching die 16. A chip removal groove 161 is provided on the punching table 1, and the punching die 16 is located above the chip removal groove 161. By providing the chip removal groove 161, the waste generated during the punching process is reduced. The chips can be discharged downward through the chip discharge groove 161. A material box 15 is fixedly installed on the upper surface of the punching table 1. By setting the material box 15, the leaf springs to be punched can be stacked in the material box 15. A discharge hopper 17 is fixedly installed at one end of the punching table 1. By setting the discharge hopper 17, the leaf springs after punching can be discharged outward through the discharge hopper 17. A limiting mechanism 2 is set on the punching table 1 and the material box 15. A feeding mechanism 4 is also set on the punching table 1 and the material box 15. By setting the limiting mechanism 2 and the feeding mechanism 4, the limiting mechanism 2 can limit and press the leaf springs to be punched, thereby improving the stability of the leaf springs during the punching process. The feeding mechanism 4 can push multiple leaf springs in the material box 15 one by one onto the punching die 16 for punching by the punching head 13, thereby improving the convenience of the loading operation during the leaf spring punching process and improving the efficiency of the leaf spring punching process.
[0032] The limiting mechanism 2 includes a first limiting plate 21 and a second limiting plate 23, with two of each. The first limiting plate 21 is slidably disposed within the material box 15. By setting two first limiting plates 21 within the material box 15, leaf springs of different widths can be limited, ensuring stable stacking of leaf springs of different widths within the material box 15. Two punching channels 22 are fixedly provided on the upper surface of the punching table 1. These two punching channels 22 are distributed on both sides of the punching die 16, allowing for the punching... The leaf spring during the pressing process can pass through two punching channels 22 and is located on the punching die 16. The second limiting plate 23 passes through the two punching channels 22. By setting the second limiting plate 23, when the leaf spring passes through the punching channel 22, the second limiting plate 23 can limit the leaf spring during the pressing process. A connecting rod 24 is fixedly set between the first limiting plate 21 and the second limiting plate 23. When the first limiting plate 21 moves horizontally in the material box 15, the first limiting plate 21 can make the second limiting plate 23 move horizontally synchronously through the connecting rod 24.
[0033] The top walls of the two punching channels 22 are provided with clamping plates 25, and the upper surfaces of the two punching channels 22 are fixedly provided with cylinders 26. The piston end of the cylinder 26 is fixedly connected to the upper surface of the clamping plate 25, and the lower surface of the clamping plate 25 is fixedly provided with anti-slip pads 27. By setting up the clamping plate 25, cylinders 26 and anti-slip pads 27, when the piston end of the cylinder 26 pushes the clamping plate 25 to descend vertically, the clamping plate 25 can press the leaf spring passing through the punching channel 22 through the anti-slip pads 27 for punching processing.
[0034] Both sides of the material box 15 are threaded rods 28. One end of the threaded rod 28 is rotatably connected to one side of the first limiting plate 21, and the other end of the threaded rod 28 is fixedly provided with a rotating wheel 29. By manually rotating the rotating wheel 29, the threaded rod 28 can be rotated, and the threaded rod 28 can drive the first limiting plate 21 to move horizontally within the material box 15. The bottom wall of the material box 15 is provided with two first guide grooves 3, and the bottom of the first limiting plate 21 is fixedly provided with two first guide blocks 31. The first guide blocks 31 are slidably disposed on the inner wall of the first guide groove 3. By setting the first guide groove 3 and the first guide blocks 31, the first guide blocks 31 can move horizontally along the inner wall of the first guide groove 3, thereby enabling the first limiting plate 21 to be guided horizontally and keep the first limiting plate 21 moving horizontally.
[0035] The feeding mechanism 4 includes a pusher plate 41. Both sides of the material box 15 are provided with through slots 42. One end of the pusher plate 41 is in contact with the inner wall of one of the through slots 42. The through slots 42 are horizontally corresponding to the punching channels 22. The height of the through slots 42 is the same as the thickness of a single leaf spring. By driving the pusher plate 41 to move horizontally, the pusher plate 41 can push the bottom leaf spring of the material box 15 into the two punching channels 22 after passing through the two through slots 42. When the pusher plate 41 moves in the opposite direction and resets, the stacked leaf springs in the material box 15 fall to the bottom wall of the material box 15 for the next feeding. A U-shaped moving frame 43 is slidably provided on the lower surface of the punching table 1. One end of the U-shaped moving frame 43 is fixedly connected to the other end of the pusher plate 41. By driving the U-shaped moving frame 43 to move horizontally, the U-shaped moving frame 43 can make the pusher plate 41 move horizontally synchronously.
[0036] A servo motor 44 is fixedly installed on the lower surface of the punching table 1. A lead screw 45 is fixedly installed at the drive output end of the servo motor 44. One end of the lead screw 45 is threadedly connected to the other end of the U-shaped moving frame 43. By starting the servo motor 44, the drive shaft of the servo motor 44 can make the lead screw 45 rotate, and the lead screw 45 can drive the U-shaped moving frame 43 to move horizontally.
[0037] The lower surface of the punching table 1 is provided with a second guide groove 46, and the other end of the U-shaped moving frame 43 is fixedly provided with a second guide block 47. The second guide block 47 is slidably disposed on the inner wall of the second guide groove 46. By providing the second guide groove 46 and the second guide block 47, the second guide block 47 can slide horizontally along the inner wall of the second guide groove 46, thereby guiding the U-shaped moving frame 43 in the horizontal direction and keeping the U-shaped moving frame 43 moving horizontally.
[0038] Working principle: When punching is required on the leaf spring, the operator first rotates the two rotating wheels 29 to rotate the two threaded rods 28. The two threaded rods 28 drive the two first limit plates 21 to move towards each other or away from each other in the material box 15, so that the distance between the two first limit plates 21 is adapted to the width of the leaf spring to be punched. At the same time, the two first limit plates 21 move the two second limit plates 23 synchronously horizontally through the corresponding connecting rods 24. Then, the leaf springs to be punched are stacked in the material box 15. At this time, the bottom leaf spring is horizontally aligned with the push plate 41.
[0039] Subsequently, the operator starts the servo motor 44. The drive shaft of the servo motor 44 causes the lead screw 45 to rotate. The lead screw 45 drives the U-shaped moving frame 43 to move horizontally. The U-shaped moving frame 43 causes the pusher plate 41 to move horizontally. The pusher plate 41 pushes the bottom leaf spring of the material box 15 to move horizontally. The pushed leaf spring separates from the material box 15 through one of the through slots 42 and enters the two punching channels 22. The opposite sides of the two second limit plates 23 contact the side of the leaf spring, and the leaf spring is located on the punching mold 16. Then, the drive shaft of the servo motor 44 is rotated in the opposite direction, causing the pusher plate 41 to move in the opposite direction and reset. At this time, the multiple leaf springs stacked in the material box 15 fall downward as a whole, and the bottom leaf spring is horizontally aligned with the pusher plate 41.
[0040] Subsequently, the operator activates two cylinders 26, the piston ends of the two cylinders 26 extend, pushing the two clamping plates 25 to descend vertically. The two clamping plates 25 press the leaf spring between the two punching channels 22 through the corresponding anti-slip pads 27. Then, the hydraulic cylinder 12 is activated, and the hydraulic cylinder 12 drives the punching head 13 to descend vertically. With the help of the punching die 16, the punching process of a single leaf spring is completed.
[0041] Subsequently, the two cylinders 26 and servo motor 44 are activated again, causing the two clamping plates 25 to move upward and reset. The pusher plate 41 pushes the bottom leaf spring of the material box 15 horizontally to the space between the two punching channels 22 for punching the next leaf spring. At the same time, the punched leaf spring is pushed to the discharge hopper 17 and discharged outward along the discharge hopper 17.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
