Claims

[Scope of utility model registration request]

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 a punch work together to draw the blank material into the die hole side and draw it into a predetermined shape. A movable floating die is provided that presses and clamps the blank material in cooperation with the holder, while the punch is provided with a movable floating die that comes into contact with the floating die at the end of forming to weaken the blank restraint force applied to the blank material. A press molding device characterized by being provided with an operating member for moving a floating die.
