UTMATNINGSENHET FOR FORMNINGSMASKINER

摘要

The disclosed ejector assembly provides for a very rapid removal of a workpiece from a forming machine by an assembly which includes a pair of ejector members operating through a hydraulic chamber. A first ejector member of the pair is directly linked to a reciprocating portion of the machine so as to follow each forming and return stroke of the machine, and the second ejector member responds to a movement of the first ejector member only during a return stroke of the machine to effect an immediate removal of a workpiece from the machine. A differential rate of travel is provided between the pair of ejector members to provide a gradually increasing clearance between the workpiece and one forming surface of the machine so that the second ejector member can immediately respond to a return stroke of the machine to cause a very rapid separation of the workpiece from a forming surface of the machine.
