PURPOSE: To prevent the development of crack, crazing, etc., at the time of squeeze molding by inclining a punch to a material flowing direction at the time of molding, arranging the punch so as to be horizontally shiftable to the same direction as the material flowing direction, synchronizing it with the ascending/lowering of a squeezing die and executing the squeezing work while shifting the punch to the horizontal direction.
CONSTITUTION: At the time of press-molding, the squeezing die 30 and a blank holder 26 holding peripheral edge part of the material W to be worked, are lowered and abutted on the tip part of the punch 25, in which the material W is inclined, to start the squeezing work. Then, while tuning with the lowering of the blank holder 26, the punch 25 starts the horizontal shifting to the inclining direction, i.e., the same direction as the material flowing direction. Therefore, the material W held with the squeezing die 30 and the blank holder 26 is sufficiently drawn in the die hole 30a from the prescribed direction with the shifting punch 25 and the flowing of the material is distributed to the regulating side, as well. Therefore, the squeeze forming can be executed without generating cracks and crazings.
