METHOD FOR MANUFACTURING MOLDED RING AND RING MATERIAL FOR MANUFACTURING SUCH A RING Russian patent published in 2019 - IPC B21K21/08 B21J13/02 

FIELD: machine building.

SUBSTANCE: invention relates to the processing of metals by pressure and can be used for fabricating rings. Ring has a base portion and two protruding portions that protrude to either side of the base portion in the axial direction of the molded ring. Ring is arranged between two half molds having recessed portions corresponding to the protruding portions of the ring. Wherein the ring is supported by one half mold in a region arranged on the outer peripheral side of the mold relative to a corner between the outer peripheral surface of the recessed portion and the surface of the outer peripheral side of the side of the recessed portion of the connector, and another half-mold in a region located on the inner peripheral side of the half-mold relative to a corner between the inner peripheral surface of the recessed portion and the surface of the inner peripheral side of the side recessed portion of the connector. Ring is compressed between the half-molds to produce a molded ring.

EFFECT: as a result, the product quality is improved due to reduced dead metal regions.
