PURPOSE:To obtain a titled device that can cope with different working by simple operation and improved in work efficiency by sending a metallic plate successively to plural lower dies by an operating device having attracting devices and performing plural times of press working successively. CONSTITUTION:In a press working device provided with lower dies 16a-e on the lower die plate 15 and upper dies 11a-d attached to an interposing plate 10 of an elevating part (omitted in the figure), a metallic plate 25 is pushed to the waiting spot 23a of a feeding plate 23 by a sliding plate 29. Then, the frame 31 of an operating device mounted to an arm 30 attached to a shaft 33 projected from a driving controlling box 32 is lowered, and operation such as attraction by attracting devices 38, 36..., advance, attaching and detaching of attracting devices 38 etc., ascent, escape etc. are performed and the metallic plate 25 is advanced successively from the die 16e to 16d. The upper dies 11a etc. are lowered when the frame 31 is escaping, and press working is performed plural times successively. The upper and lower dies 11a, 16a etc. are made easily exchangeable with different kinds of dies if necessary. |
