ABSTRACT:
A compact, controllable ejection system for use with trimming presses and forming presses. A preferred form of the invention has a remotely located sealed enclosure filled with a compressible gas and into which an incompressible fluid is introduced through a pressure line. The other end of the pressure line connects to a conventional hydraulic cylinder, the piston of which is connected to an ejector pin. During closure of the press the ejector pin is forced upwards thereby forcing fluid into the remotely located sealed enclosure. A controllable directional valve entraps the forcibly introduced incompressible fluid and the energy stored in compressing the compressible fluid. After the opening of the press, at a controlled time such as when an automated receiving tray has been inserted to receive the part, the controllable valve is opened, ejecting the part from the press.
