摘要： A formed material is manufactured by performing forming including at least one drawing-out process and at least one drawing process performed after the drawing-out process. A punch 31 used in the drawing-out process is formed to be wider on a rear end side than on a tip end side. By pushing a raw material metal plate into a pushing hole 30a together with the punch 31, ironing is performed on a region of the raw material metal plate corresponding to a flange portion.

摘要： A press formed product includes a top panel part, vertical wall parts, and ridge line parts between the vertical wall parts and the top panel part, and includes a shape-changing part in a part of the ridge line parts. 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 by using a punch, a pad arranged opposed to a front end surface of the punch, and a die capable of receiving the pad. 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, so as to form the top panel part, the ridge line parts, and the vertical wall parts.

摘要： A press-formed product that enables inexpensively providing a shock-absorbing member having a high crashing load with respect to a three-point bending load is provided. The press-formed product is a press-formed product of a steel sheet 13, the press-formed product including a body 24 having a hat-shaped cross section and extending in a direction, the transverse cross section including a bottom portion 20a and a shoulder portion 20c that is contiguous to the bottom portion 20a through an R end 25. In the transverse cross section, a first region 27 from the R end 25 to a position a predetermined distance away in a direction in which the bottom portion 20a extends, and a second region 28 that is a part of the bottom portion 20a and is contiguous to the first region 27 have a work-hardening distribution introduced by press-forming of the body 24, the work-hardening distribution being one in which average hardness Hv1 of an area of the first region 27 from a surface of the steel sheet 13 to a position with a depth obtained by multiplying a thickness of the steel sheet 13 by 0.2 and average hardness Hv2 of an area of the second region 28 from the surface of the steel sheet 13 to the position obtained by multiplying the thickness of the steel sheet 13 by 0.2 satisfy a relationship of Hv1 > 1.05 x Hv2.

摘要： A load-applying device of a press-forming die includes a rod which includes a first end, a second end, and a flange, a lamination coned disc spring in which a plurality of coned disc springs having a center hole, to which the first end of the rod is inserted, are laminated, a first plate which includes a first through hole to which the first end of the rod is inserted and abuts the lamination coned disc spring, a second plate which includes a second through hole to which the second end of the rod is inserted and abuts the flange; and a gap fixing member which is detachably provided between the first plate and the second plate and fixes a gap between the first plate and the second plate so as to maintain the gap by which the lamination coned disc spring biases the flange to the second plate. The second end and the first plate relatively move in a mutually approaching direction during press-forming, and the lamination coned disc spring is compressed.
