Abstract
In an improved crank press arrangement including a sled which is reciprocally mounted on the frame of the arrangement. A toggle lever is pivotably mounted on the sled. One arm of the toggle lever has a cam-follower roller whereas the other arm coacts with an ejector arm slidably mounted in the sled. A crank drive reciprocates the sled. A control cam is in contact with the cam-follower. The ejector rod coacts with a blank and a die to form a workpiece. The crank drive and control arm are operatively connected by means of a gear train. The contour and shape of the control cam is such that while the cam-follower roller is in continuous contact therewith, nevertheless a temporary standstill of the ejector rod occurs during the operative cycle of the arrangement.
