ABSTRACT:
A hydraulic press comprises a hydraulic drive for driving a die surface towards and away from a moving workpiece. The die surface and the hydraulic drive both move with the workpiece on rails. This is an improvement over prior art systems where only the die surface would move with the workpiece. In another aspect of the present invention a plurality of pickups also move with the hydraulic press. These pickups engage apertures in the workpiece to properly align cutting elements on the die with the workpiece. A control selectively actuates certain ones of the plurality of pickups to allow one to quickly change the size of elements formed by the die.
