PROBLEM TO BE SOLVED: To provide a press working device for enabling the working without generating defective formation in the boundary part between a shallow bent part and a deep bent part. SOLUTION: Working cams 18x, 18y and cam drivers 14x, 14y are divided into a plurality of pieces in the direction of bending edges of a workpiece 20 and a cam driver 14y for pushing out by abutting on at least one divided working cam 18y of them has a slope on the opposite side to the divided working cam 18y and is slidabie to an upper die 12. A fixed cam 24 is fixed to the lower die 16. The divided working cam 18x and the divided working cam 18y are abutted on the workpiece 20 and start working at the same time. The tips of the divided working cam 18x and the divided working cam 18y are abutted on a curved blade die 22 at the approximately same time. The timings of the completion of the working are also approximately equal. The workpiece is good worked while well adapting to the die. COPYRIGHT: (C)2004,JPO
