ABSTRACT:
A die transfer system that includes a lower die, an upper die carried for reciprocal movement toward and away from the lower die to perform at-least one operation on a workpiece positioned therebetween, and a conveyor arrangement for sequentially conveying workpieces between the dies. The conveyor arrangement includes a camshaft having an axis of rotation parallel to the direction of movement of workpieces through the die system, a transfer bar parallel to the camshaft axis carrying a plurality of hands for engaging the workpieces, and a cam arrangement coupling the camshaft to the transfer bar for moving the transfer bar both horizontally and vertically orthogonal to the camshaft axis. The cam arrangement includes a cam arm coupled to the camshaft and having a pair of angularly spaced drive rollers mounted thereon. Separate horizontal and vertical cam follower slots are disposed adjacent to the cam arm for sequential driving engagement by the rollers on the cam arm, such that rotation of the camshaft and cam arm brings the rollers into sequential engagement with the cam follower slots for driving the transfer bar horizontally and vertically with respect to the lower die.
