Abstract

PURPOSE: To enable sharp cost reduction of press forming by performing drawing, lower hole punching, burring, flange hole punching and trimming within one stroke of a press slide.
CONSTITUTION: A material to be worked is blanked with a female edge 1 and a male edge 2 by descent of a press slide. With descent of the press slide, drawing work is performed by means of a female drawing die 3, a male drawing die 5 and a blank holder 4. On completion of drawing, the blank holder 4 is thrusted by a lower die 6, and at the same time, the female drawing die reduces the pressure. Lower hole punching of the burring part is made by burring (p) 11 and a die 9, and after completion of lower hole punching, the die 9 reduces the pressure. Burring work is made with progress of press stroke. When burring work is nearly completed, punching of the flange part and trimming of outer circumference are completed by a punch 7, the male edge 2, the blank holder 4 attached to an upper die 13. At this point of time, the press slide goes to the position of bottom dead center.
