Abstract

PURPOSE: To perform ironing smoothly by subjecting a drawn cup to an inside-out process of drawing the rough inside circumferential surface inside out to the outer side and bringing the same to the outer circumferential surface of the cup through reverse drawing thence ironing the cup.
CONSTITUTION: A blank disc A is drawn by a drawing punch 1 which is formed with a rough surface 1a on the outside circumferential surface, whereby a drawn cup B coined with the inside circumferential surface on its rough surface B1 is obtained. The drawn cup B is externally fitted and set to face downward onto a reverse drawing and ironing punch 16 and a cylindrical reverse drawing die 18 projecting to the top end of a forming box 17 in opposition to a cylindrical blank holder 15. A hold-down part 15a presses the corner angle part B2 of the circumferential edge in the outside bottom of the cup B against the die 18; at the same time, the punch 16 descends and presses the cup B into the die 18, turns the surface B1 inside out to the outside circumferential surface and reversely draws tke same, whereby a drawn cup C is obtained.
