Abstract

1420646 Shearing; punching L SCHULEE GmbH 28 Feb 1973 [1 March 1972] 9732/73 Heading B3W To reduce noise during shearing or punching, a press with a mechanical main drive for the ram has a counterpressure means, acting between the ram and the press frame or the drive, which are operative progressively to apply and then relieve a force on the ram opposing the main drive respectively just before and just after a cutting tool on the ram breaks through the workpiece. As shown, Fig. 1, a ram 2 driven by a main drive crank mechanism 3, 4 is opposed via posts 10 during its working stroke by a cam drive 6, 7, out of phase with the main drive. Alternatively, Fig. 2, not shown, a main cam drive (12), (13) for ram (15) has a secondary cam 14 out-of-phase with the cam 13 acting on a frame rigid with the ram. The counterpressure means may include fluid-operated members.
