Abstract

PURPOSE: To make possible the pressing of a large-size work which does not come within the working area by converting the mechanical power of a ram to hydraulic power by means of a mechanical-hydraulic power converting cylinder on the bed of the mechanical press and operating a hydraulic press working device provided outside the press.
CONSTITUTION: A mechanical-hydraulic power converting cylinder 1 is placed on the bed 10 of a press 4, in the place apart from a hydraulic press working device 2. The large-size work 16 is placed on the bed 18 of the press working device and the press is operated. When a ram 5 descends, a piston rod 8 is pushed into a cylinder barrel 6, and mechanical power is converted to hydraulic power in an oil chamber 14. The oil pushed out from the oil chamber 14 causes a ram 19 to descend by way of a hose 28 and piston 23. In this way, with the large-size work being held placed outside the press, it is pressed by the hydraulic press working device.
