(JA) プレス成形品の製造方法
Abstract
(EN)
A method for manufacturing a press-molded article wherein a patchwork blank 1, in which a patchwork 3 is welded to a base workpiece 2 to form a thick portion 4, is prepared, only the thick portion 4 of the patchwork blank 1 is bent, and portions other than the thick portion 4 are bent in a different step than the step in which the thick portion 4 is bent.
(FR)
L'invention concerne un procédé de fabrication d'un article moulé à la presse dans lequel une ébauche de pièce 1, dans laquelle une pièce 3 est soudée à une pièce de base 2 pour former une partie épaisse 4, est préparée, seule la partie épaisse 4 de l'ébauche de pièce 1 est pliée, et des parties autres que la partie épaisse 4 sont pliées dans une étape différente de l'étape dans laquelle la partie épaisse 4 est pliée.
(JA)
プレス成形品の製造方法は、ベースワーク2にパッチワーク3を溶接して増厚部4を形成したパッチワークブランク1を準備し、パッチワークブランク1の増厚部4のみを曲げ加工し、増厚部4の曲げ加工とは異なる工程で増厚部4以外の部分を曲げ加工する。
