In the present embodiment, the base 471 is a cylindrical structure, and the punching lower module 413 and the pressing pin lower module 423 are located on the same diameter direction of the upper surface of the base 471. The base 471 is rotated 180 ° about a vertical axis by the rotary actuator 472, which switches the operating positions of the two lower modules.
When the punching lower module 413 is located at the working position, the driving end of the second driving oil cylinder 45 moves upwards to drive the punching lower module 413 to move upwards together. The lower punching module 413 is gradually close to the lower surface of the plate 200 in the height direction, at this time, the upper punching module 411 moves downward along the same vertical axis, and the two modules cooperate together to punch the plate 200, so as to form a through hole in the plate 200, thereby completing punching. After punching, the stations are switched so that the staple pressing lower module 423 is in the working position.
