RIVETING PUNCH

摘要

A riveting punch employed to punch an annular workpiece into a riveting hole defined on another workpiece. The riveting punch includes a punching member and a positioning member coupled to the punching member. The punching defines a first gas channel extending through a first end, and a mounting hole and a number of suction holes extending through a second end. The suction holes communicate with the first gas channel, and are arranged around the mounting hole. A first end of the positioning member is securely received in the mounting hole, and a second end of the positioning member has a positioning end. The guide end includes a positioning portion configured to match with the annular workpiece, and a guide portion extending from an end of the positioning portion. The guide portion includes a curved guide surface on an end.
