Abstract
A device for the ejection of a shaped part at the male die on a cross-feed press for non-cutting metal shaping is equipped with an ejector which is controlled by the crank-pin of a crankshaft via a connecting link, a cam disc and a roller arm. The cam contour P of the cam disc has an arc K concentric to the rocker shaft and joined to a straight section G and a runout section L. The cam disc has a displaceable cam shoe the outer edge of which is located in the plane of the straight section G and which extends or shortens the straight section G when shifted. This ensures that the standstill condition of the ejector with respect to the female die, required for holding the shaped part, may be retained even when adjustments are made to the length of the stroke of the ejector at the male die at the cam disc.
