PRESS COMPONENT MOLDING METHOD, PRESS COMPONENT MANUFACTURING METHOD, AND PRESS COMPONENT MOLDING DIE

摘要

PROBLEM TO BE SOLVED: To provide a press component molding method, a press component manufacturing method, and a press component molding die capable of downsizing and simplifying facility constitution by reducing load necessary for molding.SOLUTION: A press component 90 is molded by pressing a preformed article 90 in which an inclined portion 92 bent in a circular arc manner is formed on a tip end of a tapered cylindrical portion 91 with a molding die 100 including a hold body 110, a piercing punch 120, and a piercing dice 130. The molding die 100 cuts the inclined portion 92 with an outer cutting edge 122 of the piercing punch 120 and an inner cutting edge 135 of the piercing dice 130 in a state in which an outer fixed support portion 112 of the hold body 110 and an inner fixed support portion 132 of the piercing dice 130 press the cylindrical portion 91 of the preformed article 90. Subsequently, the molding die 100 tilts the remaining inclined portion 92 in a forming space FS and then compresses the remaining inclined portion 92 with a pressing portion 121 of the piercing punch 120, thereby forming corners 83.
