ABSTRACT:
An automatic die changing system for a power press having carriers for transporting dies to and from a work station in the press and having a plurality of air lines and electrical lines in the press for supplying compressed air and electrical power to the dies on the carriers. All of the air and electrical lines terminate at the surface of the press, with a normally closed valve at the end of each of the air lines and electrical contact means at the end of each of the electrical lines. A plurality of connectors are mounted on each of the carriers to register with the valves and electrical contacts when the carrier is positioned at the work station, and responsive to the lowering of the carrier onto the press bed to automatically connect the air and electrical lines at the surface of the bed with corresponding air and electrical lines for operating control devices associated with the dies on the carrier. The connectors for the air lines also have actuators for automatically opening the valves of the air lines in response to the lowering of the carrier onto the press bed.
