Abstract
An apparatus for utilizing electromagnetic energy for producing high impact forces by means of a ram propelled against a work piece. The work center of the apparatus includes a ram assembly of bolted construction having a hollow ram shaft, which ram assembly includes a gap between opposing conductive surfaces including associated fastener screws of driving disc and ram shaft of at least about five-sixteenths of an inch. A solid mass recoil assembly provides integral housing and recoil mass, enabling aerostatic bearing functioning, and also lowers shock and vibration levels to operator and equipment.
Claims3
A recoil assembly for use in an electromagnetic work tool housing enclosure having:
- an electromagnetic high energy pulse coil including a working face;
- a ram assembly including a conductive driving plate, and aerostatic bearing means comprising opposing surfaces of said working face and said conductive driving plate;
- the improvement wherein said recoil assembly comprises a solid metallic mass disposed between the inner surface of a rear wall of said housing and a major surface of said electromagnetic high energy pulse coil opposite said working face, said solid metallic mass having the front surface thereof facing said major surface of said electromagnetic high energy pulse coil opposite said working face machined perpendicular to the centerline of said ram assembly, thereby holding the working face of said electromagnetic high energy pulse coil perpendicular to said centerline of said ram assembly and maintaining substantially parallel the opposing surfaces of said aerostatic bearing means.
