[0013] 2) The lead screw is driven to rotate by the lead screw motor, and the lead screw drives the punch block slider, so that the punch block carries the metal sheet to the appropriate punching position;

[0014] 3) The cylinder drives the punch to punch holes in the metal sheet;

[0015] 4) After completing the first punching, the punching seat is moved by the lead screw, so that the metal sheet moves to another punching position, and then the punch is used to punch the new punching position.

[0016] 5) Repeat the above process according to the stamping requirements;

[0017] 6) When you need to punch holes of different diameters, simply remove the punch and replace it with a punch of a different specification.
