A method for producing a press-formed product includes a first pressing step and a second pressing step. In the first pressing step, an intermediate formed product is formed from a processed material by using first press tooling. The intermediate formed product includes a stepped section of a top plate section, a temporary vertical wall section adjacent to the top plate section via a ridge section and having at least part of the shape of the vertical wall section, and a temporary flange section adjacent to the temporary vertical wall section via a temporary ridge section. In the second pressing step, the press-formed product is formed from the intermediate formed product. In the second pressing step, forming is performed such that the temporary ridge section is moved toward the temporary flange section with at least part of the top plate section of the intermediate formed product restricted.

A method for manufacturing a molded member includes carrying out a multi-stage drawing process and at least one finishing ironing process on a base metal sheet, the molded member including a tubular body and a flange formed at an end portion of the body. The multi-stage drawing process includes a preliminary drawing process for forming a preliminary body having a body element from the base metal sheet, and a plurality of compression drawing processes performed after the preliminary drawing process, the compression drawing processes drawing the body element while applying compressive force along a depth direction of the body element to a circumferential wall of the body element. The at least one finishing ironing process is carried out such that a mold clearance of an upper portion of the body element is narrower than a mold clearance of a lower portion of the body element.

Provided is a press-formed article manufacturing method including a first step of pressing a blank with the first pressing apparatus to form a first intermediate formed article having a pair of bent portions that is bent to one side in the plate thickness direction and having a spacing between the bent portions that is narrower than the width of the top plate and equal to or more than the width of the top portion of the convex portion, and a second step of moving the second die relative to the second punch side punch with respect to the die pad and the second punch and forming a second intermediate formed article, having the standing wall formed therein, with the second die and the second punch, in a state where a portion between the bent portions is sandwiched between the die pad protruding from the second die to the second punch side punch, and the convex portion, with one side of the first intermediate formed article in the plate thickness direction as the convex portion side of the second pressing apparatus.

A producing method of the press formed product includes a preparation step of preparing a metal sheet as a starting material; and a press working step of performing press working on the starting material. The press working step includes: during a time period from when pushing-in of the starting material into the die by the punch is started or immediately thereafter until the pushing-in of the punch with respect to the die reaches a predetermined distance short of a bottom dead point for the pushing-in, holding the pad at a position distant from the punch by the predetermined distance; when the pushing-in of the punch with respect to the die reaches the predetermined distance short of the bottom dead point, receiving the pad in the die; and continuing the pushing-in of the punch with respect to the die and the pad to the bottom dead point.
