PRODUCTION METHOD FOR PRESS-MOLDED BODY, AND PRESS MOLDING DEVICE

摘要

The present invention suppresses wrinkles in ridge parts (12a, 12b) and cracks in an outwardly directed continuous flange (16) during the molding of a press-molded body (10) that has an approximately groove-shaped cross section, that has the outwardly directed continuous flange (16) provided thereto, and that is made from a high-tensile steel plate that has a tensile strength of 390 MPa or more. A method for producing a press-molded body (10) that has an approximately groove-shaped cross section, that has an outwardly directed continuous flange (16) on at least one end part, and that is made from a 390 MPa or greater high-tensile steel plate, the method comprising a first step that is for press molding after a first pad (34-1) restrains, with regard to a molding source material (33), at least one part of a section that is to be molded into a groove bottom part (11) and after second pads (34-2) each restrain at least one part of an end part of sections that are to be molded into ridge parts (12a, 12b).
