Abstract
PURPOSE:To perform compressed outside bending and inside bending to a work surely, by displacing an intermediate cam, which is provided in the lower part of an upper mold, sideways by the contact of the cam face with a lower mold and sliding a working cam provided slantwise for a cushion ring. CONSTITUTION:A cushion ring 5' rises through a cushion pin 4 by a die cushion 3, and a work 6 is set. When an upper mold 2' falls, the work 6 is bent and press-molded, and the upper mold falls together with the ring 5'. In this fall process, an intermediate cam 20 falls together with the upper mold 2' and the ring 5' as one body, and a cam face 18 is brought into contact with a cam face 32 of a lower mold 1' and is slided and receives components of a lateral pressing force and is moved to the upper left through a slide noth 15. Consequently, a cam face 19 is brought into contact with a cam face 24 of a workng cam 9' and is slided to move the cam 9' to the left, and a compression outside bending knife edge (compression inside bending knife edge) 12 is subjected to compression outside bending (compression inside bending) in an end part 6' of the work 6 as prescribed in cooperation with the ring 5'. After the press working, the upper mold 2' rises, and the ring 5' falls, and cams 20 and 9' are returned by returning springs 22 and 31.
