Abstract

PURPOSE:To obtain a press product which is high in tension rigidity, by converting an up-and-down motion of a press die to tensile force of a plate material, putting the tensile force on the plate material, and after that, press-working the plate material. CONSTITUTION:When a blank holder 5 is made to go down, the first pinch- holding surface 7 of the holder 5 press-contacts with a plate material W, and the peripheral part of the plate material W is pinch-held between said surface and an auxiliary slide 8. When a holder 7 is made to go down continuously, the peripheral part of the plate material W is depressed, being pinch-held between the first pinch-holding surface 7 and the auxiliary slide 8, in a state that the circumference of the plate material W remains press-contacted with a projecting part 2a, and tensile force is put on the plate material W. Subsequently, a punch 4 is made to go down by making an inner slide go down, and press-working of the plate material W is executed by the punch 4 and the die 2.
