Abstract

1399327 Stamping; punching; bending presses OSTERWALDER AG 8 June 1973 [8 June 1972] 27531/73 Headings B3H B3Q B3E and B3W A press for stamping, bending or punching has a plunger 4 which carries a press plate or press tool on its face 30 and is reciprocated into a working position by an eccentric 1 and moved hydraulically through a working stroke. The eccentric 1 has a connecting rod 2 to a piston 3 in a cylinder of the plunger 4. At the end of the eccentric approach stroke the cylinder space 7 is hydraulically pressurized to move the plunger 4, the movement being limited by stops 6, 29. The other cylinder space 10 is constantly pressurized pneumatically or hydraulically for the plunger return stroke. Rollers 15, 15<SP>1</SP> are provided between the piston 3 and the connecting rod 2. The stroke of the plunger is adjustable by a screw 6. The eccentric drive moves the plunger press plate or tool close to the other tool for the final hydraulic working stroke. The sequence of operations is controlled by cam or photo-electric operated limit switches.
