FIELD: metal forming.
SUBSTANCE: inventions of the claimed group relate to metal forming, particularly, to cup-like part drawing on drawing press. Press used is clamping ring clamping metal sheet to draw cup-like part. Pressure ring comprises an inner surface defining an exhaust opening configured to receive a male die therein. Clamping surface comprises forces concentration segments separated by unloading zones. First force concentrating segment is arranged circumferentially at the distance from second force concentration segment, and each of them comprises concentric arched grooves.
EFFECT: decreased festoon formation in cup-shaped part.
