PURPOSE:To supply an energy matched to the press working to materials to be worked, by providing a clutch hub and a rotating member on the driving shaft of a press machine and providing the first clutch between the clutch hub and the rotating member and providing the second clutch between a flywheel and the rotating member. CONSTITUTION:A clutch hub 4 is provided on a driving shaft 1 of a press working machine, and a rotating member 3 is supported freely rotatably on the driving shaft 1, and the first clutch 22 consisting of frictional plates 5 and 6 and a piston 12 is interposed between the clutch hub 4 and the member 3. A flywheel 2 is supported freely rotatably for the driving shaft 1 and the rotating member 3, and the second clutch 23 consisting of frictional plates 10 and 11 and a piston 13 is interposed between the flywheel and the rotating member 3. In the operation, the rotation force of the flywheel 2 is transmitted to the driving shaft 1 through clutches 22 and 23 and the clutch hub 4, and a slide is driven by a gear, a crank mechanism, etc. hereafter; and thus, the energy held in the rotating member 3 is adjusted by the rotation number to supply an energy required for the press working. |
