ABSTRACT:
A forging machine transfer is disclosed which is operable in response to transfer movement to turn a gripped workpiece about an axis perpendicular to a plane containing the axis of an elongated workpiece. A single pivoted gripper grips the workpiece against a flat, nonrotating platform and causes the workpiece to slide along such platform as the workpiece is transferred to a subsequent work station. The pivot axis is eccentrically located so that the workpiece is moved toward the die face during transfer to be properly positioned for subsequent working at the delivery position. A pivoted drive linkage provided to produce the rotation is located above the work station to reduce the likelihood of bearing damage resulting from scale or the like. The angle through which the workpiece is rotated can be selected within a range substantially greater than 90 degrees and substantially less than 90 degrees.
