ABSTRACT:
In a method of producing a socket plate for wobble plate compressors an insert ring and a holed socket plate parent metal, having different mechanical and physical properties, are formed through extrusion processes prior to hot-forging the parent metal with the ring into a resulting socket plate. In the hot-forging step, the insert ring is seated onto the ring seat of a bottom mold prior to fitting the parent metal over the ring. Thereafter, a top mold is lowered onto the bottom mold, thus forming the resulting socket plate. A plurality of lubrication grooves are formed on the internal surface of the ring during the hot-forging step, with a plurality of projections being formed on the external surface of the ring. The projections bite into the inside wall of the holed parent metal thus integrating the ring with the parent metal into a single body.
