US Patent 7331244 Stamping press line simulation device and method

An apparatus and method for testing a stamping press die that has includes a plurality of mechanical devices. The apparatus includes a plurality of pneumatic connections for supplying pressurized air to each of the plurality of mechanical devices; a plurality of valves for regulating pressurized air to associated connections at a predetermined pressure and flow, so as to actuate the associated mechanical devices; and a control system for selectively controlling the plurality of valves, so as to implement a predetermined sequence of valve actuations. In this way, the control system simulates a predetermined sequence of mechanical device operation while the die is removed from the stamping press.
