Die-side ejector device for workpieces in single-stage or multi-stage presses
In a die-side ejector device for presses, a stationary press die cooperates with a press ram on a press frame in order to shape a blank introduced into a bore of the press die. An ejector pin is displaceably provided in a bore in the press frame, said ejector pin being biased against an ejector leve...

description | In a die-side ejector device for presses, a stationary press die cooperates with a press ram on a press frame in order to shape a blank introduced into a bore of the press die. An ejector pin is displaceably provided in a bore in the press frame, said ejector pin being biased against an ejector lever which is pivotable by an actuator lever between a starting position and a final ejection position and which is supported, on its side facing away from the ejector pin in its starting position, on a pressure piece on the press frame. The ejector lever is pivotably arranged on a carrier part, which is displaceable on the press frame, perpendicular to the longitudinal axis of the ejector pin and in parallel with the plane of pivot of the actuator lever, between two stops and is provided, in order to contact the pressure piece, with a shaped surface which may be brought into areal contact with a complementary shaped surface on the pressure piece, wherein both shaped surfaces maintain their areal, complementary contact in the starting position of the ejector pin even upon displacement of the carrier part. |
