Title
(EN) MOLDING METHOD OF PRESS COMPONENT
(JA) プレス部品の成形方法
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a molding method of a press component which can suppress occurrence of molding failure such as a wrinkle and a wrinkle overlap at a flange part even when a curved press component is pressed and molded.

SOLUTION: A molding method of a press component is the molding method of the press component which presses and molds the curved press component formed of a top surface part 3, side wall parts 5, and flange parts 7 in a hat shape in cross section. The molding method includes a preliminary molding process of molding folded parts 11 which extend in a longitudinal direction at end parts in a width direction of a flat plate-like blank, and a main molding process of molding the top surface part 3 and the side wall parts 5 in a state that the folded parts 11 are remained.

【課題】湾曲プレス部品をプレス成形する場合にも、フランジ部におけるシワやシワ重なり等の成形不良の発生を抑制することができるプレス部品の成形方法を提供する。
【解決手段】本発明によるプレス部品の成形方法は、天面部3、側壁部5およびフランジ部7から断面ハット状に形成される湾曲プレス部品をプレス成形するプレス部品の成形方法である。そして、平板状のブランク材の幅方向端部に長手方向に沿って延在する折曲部11を成形する予備成形工程と、折曲部11を残した状態で天面部3と側壁部5を成形する本成形工程と、を有する。
