[0035] Working principle: The utility model is a punching device for processing automobile fenders. During use, the movable die 14 and the die base 6 are replaced according to the punching operation needs. When replacing the die base 6, the first screw 9 is unscrewed and the fixing of the mounting plate 8 is released, thereby removing the die base 6. When installing, the first screw 9 only needs to pass through the mounting plate 8 and be tightened on the top of the workbench 1, thereby completing the replacement of the die base 6.

[0036] When replacing the movable mold 14, unscrew the second screw 16, unfasten the fixing of the movable mold 14, and then move the movable mold 14 horizontally to the front side. The movable mold 14 drives the hanging plate 17 to move away from the cross plate 13, thereby removing the movable mold 14. When installing the movable mold 14, first move the movable mold 14 to the front side of the cross plate 13 so that the inner top of the hanging plate 17 is flush with the top of the cross plate 13, and then move the movable mold 14 to the rear side. The movable mold 14 drives the hanging plate 17 to move so that the hanging plate 17 moves to the top of the cross plate 13. At this time, the hanging plate 17 hangs the movable mold 14 on the cross plate 13. The operator does not need to lift the movable mold 14, but only needs to tighten the second screw 16 to complete the installation of the movable mold 14. The replacement operation of the movable mold 14 is simple and labor-intensive.

[0037] After that, the fender to be punched is placed on the top of the die base 6, and then the movable plate 18 is flipped. The movable plate 18 is flipped around the adjacent pin shaft 29, and the movable plate 18 drives the rubber head 22 to flip until it fits with the top of the fender. Then, the nut 25 is driven to rotate by rotating the second operating rod 26. The nut 25 moves downward on the outer edge of the second threaded rod 24. The nut 25 presses the movable plate 18, thereby pressing the rubber head 22. At the same time, the first operating rod 21 can be rotated. The first operating rod 21 drives the first threaded rod 20 to rotate in the inner cavity of the screw hole 19. The first threaded rod 20 moves downward under the action of the thread. The first threaded rod 20 drives the rubber head 22 to move downward, so that the rubber head 22 fits tightly with the fender, greatly improving stability and avoiding deviation of the fender during punching, thereby ensuring the normal progress of the punching work.

[0038] After that, the hydraulic rod 11 is started by an external power supply. The hydraulic rod 11 drives the movable mold 14 and the punching head 15 to move downward through the transmission rod 12. The punching head 15 punches the fender. The punching head 15 passes through the fender to complete the punching. The waste parts left by the punching pass through the discharge port 5 to reach the inner cavity of the storage bin 2, and fall into the storage box 3 under the action of gravity. After the punching work is completed, pull the handle 4 to move the storage box 3 out to clean the waste parts, which is convenient for cleaning up the waste chips.
