Abstract

PURPOSE:To obtain a titled die capable of performing an accurate press forming by inserting a rotary cam, having a composite bending part for holding a blank material in cooperation with a holding part of a lower die, and mounting the blank material in a stable state on the lower die. CONSTITUTION:A rotary cam 23 having a composite bending part 25 at its one end is inserted in a cam groove 22 consisting of a circular arcuate surface formed in the inside of a lower die 20 which is provided, at its left end upper part, with a holding part 21 for holding a blank material of pillar A having a press-formed left part. After mounting the blank material on said holding part 21; when an upper die holder 30 which holds a pad 31 through a spring 32 and a suspension cam 33 through a sliding bed 34 is lowered, the pad 31 presses the blank material against the holding part 21 and, at the same time, the suspending cam 33 presses a sliding plate 24 downward to turn the cam 23; then the part 25 holds stably the material in cooperation with the part 21. Next, the cam 33 moves on the plate 24 in the arrow III direction to press the material by a composite blade 35 provided to the lower end of the cam 33 thereby forming a pillar A of a prescribed shape.
