摘要： The invention provides inexpensively a pierce die by omitting a large pad at the time of executing a piercing process and pressing a work at only a minimum portion required for the piercing process, thereby reducing the portion to be machined as much as possible. There is provided a punch stripper comprising a pierce punch, a punch retainer holding the pierce punch, a cover which covers the pierce punch so as to protrude a leading end portion of the pierce punch, and is fastened by screws to the punch retainer, a stripper which is outward fitted to the pierce punch, presses the work before piercing the work by the pierce punch, takes out the pierce punch from the work after piercing, is received within the cover so as to move forward and backward, and forms a stop flange in a rear end, and a coil spring which is received within the cover so as to bring the stripper into contact with the stop flange, and energizes the stripper toward an outer side.
