Abstract

1,098,197. Metal working presses. H. SCHMID. April 9, 1965 [April 10, 1964], No. 15072/65. Headings B3H and B3W. An hydraulic press, particularly for punching out a blank, has its ram formed in two parts 3, 4, Fig. 1, which are relatively adjustable by hydraulic means. This varies the stroke position of the ram. The ram works in a cylinder 2 and is actuated in both directions by hydraulic fluid supplied through pipes 6, 7. Inner ram part 3 has an upper face 15 receiving a die, punch or other press tool and has piston faces 10, 11, 12 working in cylinder spaces in the outer ram part 4. Hydraulic fluid from a reservoir 20 is supplied by a swash plate pump 19 through pipes 13, 14 to the piston faces 10 and 11 or to the piston face 12, under the control of push-button actuated valve units 25, 26. A switch contact 18 on the outer part 4 is engaged by a friction fitted collar 17 on the inner part 8 to actuate the valve unit 25 in case there is a loss of fluid in the chambers. In another embodiment, Fig. 2 (not shown), the two ram parts are arranged in tandem and the collar 17 can be locked in position by hydraulic means.
