成したことを特徴とするプレス装置。 In a press device that is configured to perform press forming by applying a bottom pressing load to a die that strokes along a pair of die holders sandwiching both sides, and by making a punch stroke with a predetermined load, A press surface that changes three-dimensionally is symmetrical on both sides in a center cross section perpendicular to the press direction, and a center cross section perpendicular to the press direction forms a press surface that changes three-dimensionally and is symmetrical on both sides, and a relative surface of the pair of die holders formed corresponding to the press surface is formed at a center cross section perpendicular to the press direction. The die, punch, and die holder are configured to be integrally provided at both ends in the press direction so that both sides are symmetrical in the cross section, and are pressed by inverting and pressing the die, punch, and die holder to form two types of press parts that are three-dimensionally symmetrical. A press device characterized in that it is configured to mold.
