The punching process is an indispensable part of the bumper's production.

[0003] A search revealed that patent application CN202021888598.X discloses a punching device for automobile bumper production, comprising a base, a clamping plate, and a clamping plate. A support rod is fixedly mounted at one end of the top of the base, and an mounting rod is fixedly mounted at the top of the support rod. A drive motor is fixedly mounted at one end inside the base, and a threaded shaft is movably mounted at the output end of the drive motor. The top of the threaded shaft is connected to one end of the bottom of the mounting rod via a bushing. A threaded sleeve is fitted onto the surface of the threaded shaft, and a movable rod is fixedly mounted on one side of the threaded sleeve. Two limiting grooves are formed at the top of the interior of the base, and sliding rods are fixedly mounted inside each of the two limiting grooves. Pressure blocks and second springs are fitted onto the surfaces of both sliding rods. This invention, through a series of structural features, provides good positioning and facilitates cleaning of the LCD screen surface, but it still has the following drawbacks:
