Abstract
A device for ejecting a workpiece from a die having a two-armed ejector lever, the drive-side arm of which can be driven by driving rods. The ejector-side arm acts upon an ejector slide. The ejector lever is adjustable for changing the ejector lift. In order to integrate the compensation for different ejection lengths into the ejector lever, the working plane on the drive side and the take-off plane on the ejector side are to be arranged in parallel to the adjustability of the ejector lever. On the other hand, the ejector lever must have a different width in the area between the take-off plane and the bearing which supports the ejector lever during the forming, for projections of different lengths at the workpieces. The width is obtained from the distance of the take-off plane in ejector position of the ejector lever from the bearing minus the length of the ejector lift in this position.
