Beschreibung
Zusammenfassung:	The punching device comprises a U-shaped frame, the upper surface of the U-shaped frame is fixedly connected with a clamping block, the surface of the clamping block is rotationally connected with a punching part, the two sides of the outer surface of the U-shaped frame are fixedly connected with supporting plates, the surface of the U-shaped frame is fixedly connected with a connecting base, and the surface of the U-shaped frame is fixedly connected with a clamping block. The lower surface of the connecting base is fixedly connected with a side plate, the side plate is fixedly connected with the outer surface of the U-shaped frame of the connecting base, and the upper surface of the connecting base is fixedly connected with a lantern ring. According to the punching device for the annular workpiece, a worker presses a pressing block downwards to enable the pressing block to drive a connecting plate to slide downwards on the surface of a sliding groove, and a spring at the bottom of the connecting plate is ext
