PROGRESSIVE FEEDING PRESS WORKING DIE UNIT, PROGRESSIVE FEEDING PRESS WORKING DEVICE, AND METHOD FOR MANUFACTURING THREE-DIMENSIONAL PRECISION PART USING THE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a press working die unit, a press working device, and a press working method, wherein a workpiece can be easily raised by a simple structure even when complicated bending work is performed in progressive feeding.;SOLUTION: A rotary plate 12 is provided on an upper face of a die body 11 for performing bending work. The rotary plate 12 is rotatably pivoted between a working position P1 and a passing position P2 and is urged by a spring 15 to be returnable. The rotary plate 12 is supported to function as a die on the upper face of the die body 11 until completion of the bending work. When a workpiece w is moved upward for progressively feeding the workpiece w, the rotary plate is pushed by the workpiece itself and rotated to a position to allow the workpiece w to pass, and returns after passing of the workpiece.;COPYRIGHT: (C)2013,JPO&INPIT
