摘要： PROBLEM TO BE SOLVED: To provide a metal closed-section member with a flange portion integrally bending-formed at the end thereof in a longitudinal direction without forming a flange portion that is used only in the production of a closed-section member. SOLUTION: A closed-section member is produced from a plate workpiece W1 by press-forming a metal plate workpiece W1 into a convex form while forming a convex portion protruded in an opposite direction at the convexed top face, press-forming a convex portion in a direction that the plate workpiece W1 is protruded in the convex form to collapse the convex portion and, further, displacing the convexed side faces inward to form a closed-section. In this production process, before the press-forming of the convex portion, the end opposite to the convexed top face side of the convexed side face is bending-formed inward the plate workpiece. Further, in this case, at the convexed side face, flange portions W4f, W4g provided integrally at the end in a longitudinal direction of the plateworkpiece W1 are bending-formed against the longitudinal direction of the plate workpiece W1.

摘要： PROBLEM TO BE SOLVED: To manufacture a metallic member having a closed section by a relatively simple method while suppressing occurrence of spring-back. SOLUTION: A punch 42 is moved in a state that a metallic plate workpiece W1 is held by a blank holder 41 with respect to a die 45; the plate workpiece is press-formed in a projecting shape, and a projecting part projected in the opposite direction is formed on a projecting top face part W2. The projecting part of the press-formed plate workpiece is press-formed in the projecting direction in a projecting shape of the plate workpiece by a core die. Both projecting side face parts W3, W4 of the projecting top face part of the plate workpiece are inwardly displaced, respectively, to form a closed section. When manufacturing a member having the closed section from the metallic plate workpiece, the plate workpiece holding force for holding the plate workpiece with respect to the die by the blank holder is set to be smaller during the projecting part forming when the projecting part is formed as compared with the time when the press forming starts, where the plate workpiece is press-formed in the projecting shape.
