METHOD FOR MOLDING PRESSED COMPONENT, METHOD FOR MANUFACTURING PRESSED COMPONENT, AND DIE FOR MOLDING PRESSED COMPONENT

摘要

Provided are: a method for molding a pressed component, whereby the efficiency of manufacturing and the material yield rate can be enhanced in a metal pressed component in which a flange part is formed at one end part in a cylindrical boss part; and a die for molding the pressed component is provided. A piercing die (110), a piercing punch (120), and a pedestal (130) are used to mold a pressed component (90). The piercing die (110) is configured from a cylindrical first molding part for molding a boss part (91), and a second molding part having an overhanging part (112a) and a cutting blade (112b) for pressing on, while cutting, a portion of a preliminary molding (90'). A cutting blade (120a) as a counterpart to the cutting blade (112b) is formed in a distal end part of the piercing punch (120). During molding of the pressed component (90), a tip part (93) of a preliminary molding (90') obtained by drawing a blank (80) is parted by the cutting blade (112b) and the cutting blade (120a), after which a preliminary boss part (91') is pressed and upset by the overhanging part (112a).
