Abstract

PURPOSE:To improve the performance of a product by providing a punch cutter capable of relative travel to a center punch and forming a recess for a reinforcing protrusion at the lower end part of the punch cutter. CONSTITUTION:The punch cutter 34 moving relatively for the center punch 32 of a punch assembly body 26 is provided to form the recess 100 on the inclined edge of the lower end. With the lowering of a movable base 22 the punch assembly body 26 is lowered towards a front formed body 102 and forms a cylindrical skirt wall 6 in cooperation with the punch cutter 34 and the head part 78 of the cutter die 62. When the cutter 34 is lowered further, after a protrusion formed by the recess 100 on the front formed body 102 passes the recess 100, the protrusion is crushed sequentially to obtain the desired reinforcing protrusion 18 for a holding piece 8. As a result, since change of equipment is hardly required to form the desired reinforcing protrusion 18, the manufacturing cost is not increased and the performance of the product is improved.
