Abstract
A hydraulic driven press for embossing, bending, stamping, especially fine or precision blanking, comprising a plunger or ram guided in an upright or stand. The plunger or ram is supported at the stand by means of pressure chambers and a piston, the pressure chambers comprising at least one actuation pressure compartment and a counter pressure compartment which are supplied by a pump or the like with a pressurized medium. Devices measure and determine the displacement path of the plunger or ram and the plunger or ram speed as well as the delivered quantity of pressurized medium. There is also provided a regulation device for regulating plunger or ram movement as a function of the aforementioned measurement values.
