とを特徴とするプレス成形装置。 In a press forming machine that presses and holds a blank material between a die with a die hole and a blank holder, the die and punch work together to pull the blank material into the die hole side and draw it into a predetermined shape. An insert blank holder is provided that is movable relative to the blank holder in the pressing direction and contacts the blank material before the blank holder, and the insert blank holder is provided between the insert blank holder and the blank holder or between the insert blank holder and the punch. The press forming apparatus is characterized in that the insert blank holder is provided with an elastic means for applying a blank pressing force.
