ABSTRACT:
A pressure set for use in a stamping press has a pressure cylinder placed between an upper and lower plate of the pressure set. In addition, an adjustable pressure regulating means is coupled to the cylinder for changing the pressure applied between the upper and lower plates. A controller coupled to the adjustable pressure regulator adjusts the pressure in the pressure cylinder to provide a predetermined pressure between the upper and lower plates.
