Title (EN) METHOD FOR MANUFACTURING PRESS MOLDED PRODUCT
(FR) PROCÉDÉ DE FABRICATION DE PRODUIT MOULÉ À LA PRESSE
(JA) プレス成形品の製造方法
Abstract:
(EN) A method for manufacturing a press molded product is provided with a step for forming a plurality of angled parts (31G) in a part (31) to be pressed in a member (30) to be pressed, a step for disposing the member (30) to be pressed between a first mold (10) and a second mold (20), and a step for press molding the part (31) to be pressed such that the height of the part (31) to be pressed becomes smaller. In the step for press molding, a pair of first curved parts (31A) curved convexly toward the second mold (20) is formed in the part (31) to be pressed by the angled parts (31G). While holding the pair of first curved parts (31A) by a pair of holding parts (20B), a second curved part (31B) curved convexly toward the first mold (10) from a position between the pair of first curved parts (31A) is formed in the part (31) to be pressed by the angled parts (31G), and the second curved part (31B) is deformed by press.
(FR) Un procédé de fabrication d'un produit moulé à la presse comprend une étape consistant à former une pluralité de parties inclinées (31G) dans une pièce à presser (31) appartenant à un élément à presser (30), une étape consistant à disposer l'élément à presser (30) entre un premier moule (10) et un second moule (20), et une étape consistant à mouler à la presse la pièce à presser (31) de façon à réduire la hauteur de la pièce à presser (31). Lors de l'étape de moulage à la presse, une paire de premières parties incurvées (31A), présentant une convexité dirigée vers le second moule (20), est formée dans la pièce à presser (31) par les parties inclinées (31G). Tout en maintenant la paire de premières parties incurvées (31A) au moyen d'une paire de parties de maintien (20B), une seconde partie incurvée (31B), présentant une convexité dirigée vers le premier moule (10) à partir d'une position entre les premières parties incurvées (31A), est formée dans la pièce à presser (31) par les parties inclinées (31G), et la seconde partie incurvée (31B) est déformée par compression.
(JA) プレス成形品を製造する方法であって、被プレス部材(30)の被プレス部(31)に複数の角部(31G)を形成する工程と、被プレス部材(30)を第1金型(10)と第2金型(20)との間に配置する工程と、被プレス部(31)の高さが小さくなるように被プレス部(31)をプレス成形する工程と、を備え、プレス成形する工程では、被プレス部(31)において第2金型(20)に向かって凸状に屈曲する一対の第1屈曲部(31A)を角部(31G)により形成し、一対の第1屈曲部(31A)を一対の保持部(20B)により保持しつつ、被プレス部(31)において一対の第1屈曲部(31A)の間の位置から第1金型(10)に向かって凸状に屈曲する第2屈曲部(31B)を角部(31G)により形成し、第2屈曲部(31B)をプレスして変形させる。
