METHOD FOR PRODUCING PRESS-MOLDED PRODUCT, PRESS-MOLDED PRODUCT, AND PRESSING DEVICE

摘要

The method for producing a press-molded product according to the present invention is a method for producing a press-molded product that includes: a long top plate; a wall having a sharply curved part that is connected on one end to the edge of the top plate in the lateral direction, and which curves in a protruding manner towards the opposite side of the top plate when viewed from above the top plate; and a flange that is joined to the other edge of the wall, and that extends towards the opposite side from the top plate side in the plate thickness direction of the wall. Said method includes a first step in which an intermediate molded product including a temporary flange is molded using a press, and a second step in which a press is used to deform the temporary flange in such a manner that a specific part that is joined to the sharply curved part in the temporary flange has an angle formed with respect to the sharply curved part that increases or decreases continuously from one end to the other at each part in a longitudinal direction, thereby transforming the temporary flange into the flange.
