A method is provided for manufacturing a terminal member that is electrical conductive with a conductive member. The terminal member is formed by working a workpiece having a plate shape with a first surface and a second surface extending from one end toward the other end, by cutting out a recessed portion at the one end from the first surface to the second surface. In this method, the recessed portion is supported by being abutted against a supporting member, and a portion spaced from the recessed portion toward the other end side is fixed, and both side portions along the one end from the recessed portion are bent while being pressed from the first surface toward the second surface side, thereby forming, as a pair of conductive surfaces for conduction with the conductive member, second surface portions facing each other with the supporting member interposed therebetween.

A laminated work production apparatus for producing a laminated work by punching a plate-like metal material into a plate-like work of a predetermined shape and stacking a plurality of the plate-like works includes a mold for punching the metal material, a stacking jig moving mechanism for moving a stacking jig to a stacking position where the plate-like works are stacked, a retention mechanism for retaining the punched plate-like works at a retaining position different from the stacking position until a preset number is reached, and a knockout mechanism for knocking out a plurality of plate-like works in a punching direction and stacking the plate-like works on the stacking jig arranged at the stacking position when the preset number of plate-like works are retained in the retention mechanism.

Laminated work production method

A preform having edges overlapped and jointed, two outer members for forming outer surfaces of a hydroformed product, and reinforcement members for forming reinforcement ribs that divide a hollow cross section of the hydroformed product, including a joint formed by, when more than three sheet materials for forming the outer members and the reinforcement members are overlapped together, welding a first sheet material on a surface of the overlapped sheet materials to a second sheet material positioned inside the first sheet material, and a space disposed and aligned with a joint plane between the second sheet material and a third sheet material located inside the second sheet material during the welding process.

Preform, hydroforming method, and hydroformed product

A preform with edges overlapped and jointed each other and first and second outer members for forming outer surfaces of a hydroformed product, and reinforcement members that are jointed to the first and second outer members to form reinforcement ribs that divide a hollow cross section of the outer surfaces, the reinforcement members having dimensions capable of suppressing elongation in a tensile direction due to a tensile force that develops during hydroforming.
