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.
Claims35
A removable pressure set for placement between a die and a surface of a press comprising:
- an upper plate for placement adjacent the die;
- a lower plate for placement against the surface of the press;
- a pressure cylinder placed between said upper plate and said lower plate;
- an adjustable pressure regulator coupled to said cylinder that controls the pressure applied between said upper plate and said lower plate;
- and
- a computer controller coupled to said adjustable pressure regulator that communicates to said adjustable pressure regulator to provide a predetermined pressure between said upper plate and lower plate.

A removable pressure set for placement between a die and a surface of a press comprising:
- an upper plate for placement adjacent the die;
- a lower plate for placement against the surface of the press;
- a pressure cylinder placed between said upper plate and said lower plate;
- pressure regulating means coupled to said cylinder for remotely controlling a pressure applied between said upper plate and said lower plate;
- and
- computer control means coupled to said adjustable pressure regulating means for communicating with said adjustable pressure regulating means to provide a predetermined pressure between said upper plate and lower plate;
- said pressure regulating means comprises internal pressure adjustment means coupled within said pressure cylinder for regulating the pressure within said pressure cylinder and external adjustment means coupled to said internal pressure adjustment means for adjusting said internal pressure adjustment means;

A removable pressure set for placement between a die and a surface of a press comprising:
- a support frame;
- and
- a plurality of pressure modules supported by said frame, each of said pressure modules having independently remotely adjustable pressures;
- each of said modules having an upper plate for placement adjacent the die;
- a lower plate for placement on the surface of the press;
- a pressure cylinder placed between said upper plate and said lower plate;
- and
- an adjustable pressure regulator coupled to said cylinder that controls the pressure applied between said upper plate and said lower plate;
- said adjustable pressure regulator comprises a plurality of adjustable metering components coupled within said pressure cylinder to control the pressure within said pressure cylinder;
- said adjustable metering components comprise a first tube having a plurality of orifices and a second tube having a plurality of metering slots, said first tube and said second tube being relatively adjustable so that an alignment of said slots with said orifices may be changed;
- said pressure cylinder comprises a piston operatively coupled to said upper plate and within said first tube, and a fluid accumulator, so that when a pressure is placed on said upper plate, said piston forces a hydraulic fluid to flow though said slots and orifices at a predetermined rate depending on said alignment of said slots with said orifices;
- said pressure regulator comprises an adjuster external to said pressure cylinder and coupled to said adjustable metering components;
- said adjuster comprises a first gear concentric with said pressure cylinder;
- said adjustable pressure regulator further comprises a motor and a second gear coupled to said motor, said first gear cooperating with said second gear to adjust said adjustable metering components.
