[0002] A punching press is a mechanical device used to punch holes in various types of plates, strips, etc. It uses the strong pressure and punch of the punch to quickly punch a hole in the material (such as metal plates, plastic plates, etc.). Punching and stamping are widely used in various fields of manufacturing, such as automobile manufacturing, electronic equipment production, metal product processing, etc. It is a very important processing method.

[0003] The prior art includes a utility model with publication number CN206415476U. The utility model discloses a punching machine, which aims to solve the problem of difficulty in cleaning the punching machine. The key points of the technical solution are a punching machine, including a punching machine body, on which an upper pressure head and a lower pressure head relative to each other are arranged, the upper pressure head is provided with a punching body, the lower pressure head is provided with a support body corresponding to the punching body, the support body is provided with a chip falling hole, the lower pressure head is provided with a cleaning hole connected with the chip falling hole, the lower pressure head is provided with two parallel support rods, and a chip conveyor belt is arranged around the two support rods, through which a chip conveyor belt is arranged. Rotating the support rod can drive the chip conveyor belt to rotate, one end of the chip conveyor belt is located outside the cleaning hole, and the middle part is located just below the chip falling hole in the cleaning hole. The punching punching machine of the utility model has low cleaning difficulty, and solves the problem that the debris of spare parts left after punching needs to be cleaned every time, so a chip falling hole is opened on the support body, and a cleaning port connected with the chip falling hole is opened on the lower pressure head.
