The ejector pin for ejecting a workpiece from a die of a stamping machine is actuated by means of a cam shaft oscillated back and forth on the machine frame through less than one revolution, a radial cam mounted on the shaft, and a motion transmitting rocker carrying a cam follower. The stroke of the ejector pin can be set by angularly shifting the position of the cam on the shaft, the angular length of the cam shaft being greater than the angular spacing of the terminal shaft positions. The portion of the cam face first engaged by the cam follower during the working stroke of the ejector pin spirals uniformly outward from the cam shaft axis to an outermost position which is reached before the cam shaft movement stops. |
