PURPOSE:To reduce the space to be used and to perform efficiently intricate pressing by providing two units of crank presses in combination with one crank shaft and performing plural pressing with respective dies. CONSTITUTION:A crank shaft 23 is used commonly by two units of crank presses 21, 24, and respective bolsters 26, 25 are positioned on the same plane. The material (a) conveyed from a material supplying device 28 is worked on the bolster 26 of the 1st press 21 by means of suitable dies 31a, 31b. The material is then conveyed onto the 2nd press 24 by the conveying path 27 of the frame 22 thereof and is continuously worked on the bolster 25 thereof by suitable dies 25a, 25b. The product 32 cut therein is taken out by a chute 33 to a receiving means 34. The conveyance of the material is thus simplified and working efficiency is improved. |
