ABSTRACT:
A pressure intensifier drive unit has walls that form a cylinder with an intermediate divider plug separating a working chamber and a pressure intensifying chamber aligned in the cylinder. The working chamber has a working piston and a working piston rod extending from an end of the cylinder. A carrier piston is located between the working piston and the divider plug and has a cylindrical recess receiving the working piston, a hydraulic fluid chamber, and a bore. A locking piston is movably mounted on the carrier piston and locks the carrier piston in place when the working piston rod initially contacts a workpiece. A pressure intensifier piston in the pressure intensifying chamber has a pressure intensifier piston rod extending through a bore in the divider plug and through the bore in the carrier piston into the hydraulic fluid chamber. With the carrier piston locked and the pressure intensifier piston rod moving into the hydraulic fluid chamber, the working piston and working piston rod are moved more slowly and under higher pressure against the workpiece. Gas, preferably air, is used to power all three pistons in the working chamber and the pressure intensifier piston in the pressure intensifying chamber. The pistons are also returned to their initial positions by air. Hence, air under pressure is the only external fluid required for operating the drive unit.
