Abstract
(EN) The present invention is a press-molding device (30) for producing a press-molded article having a hat-shaped cross section by compressing a preform having a hat-shaped cross section between a punch (31), which is a first mold, and dies (32a, 32b), which are a second mold, and is characterized by being provided with: the punch (31) and the dies (32a, 32b), which constitute a compression mechanism for compressing side walls and a flange of the hat shape of the preform; compression blocks (34a, 34b), which constitute a first pressing mechanism for pressing an outer end portion of the flange of the hat shape of the preform; and a pad (35a), which constitutes a second pressing mechanism for pressing an upper end portion of the side walls of the hat shape of the preform.
(FR) La présente invention est un dispositif de moulage à la presse (30) destiné à produire un article moulé à la presse ayant une section transversale en forme de chapeau par compression d'une préforme ayant une section transversale en forme de chapeau entre un poinçon (31), qui est un premier moule, et des matrices (32a, 32b), qui sont un second moule, et est caractérisé en ce qu'il comprend : le poinçon (31) et les matrices (32a, 32b), qui constituent un mécanisme de compression pour comprimer des parois latérales et une bride de la forme de chapeau de la préforme ; des blocs de compression (34a, 34b), qui constituent un premier mécanisme de pressage pour presser une partie d'extrémité externe de la bride de la forme de chapeau de la préforme ; et un tampon (35a), qui constitue un second mécanisme de pressage pour presser une partie d'extrémité supérieure des parois latérales de la forme de chapeau de la préforme.
(JA) 本発明は、第一金型であるパンチ(31)と第二金型であるダイ(32a,32b)との間で断面ハット形状の予備成形品を圧縮して断面ハット形状のプレス成形品を得るプレス成形装置(30)であって、予備成形品におけるハット形状のフランジと側壁とを圧縮する圧縮機構を構成するパンチ(31)及びダイ(32a,32b)と、予備成形品におけるハット形状のフランジの外側端部を押圧する第一押圧機構を構成する圧縮ブロック(34a,34b)と、予備成形品におけるハット形状の側壁の上側端部を押圧する第二押圧機構を構成するパッド(35a)と、を備えることを特徴とする。
