FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy, particularly, to cold forging. Proposed device comprises cone with guide grooves, thrust ring, sliding sectors, female die and elastic element composed of tapered shell arranged between sliding sectors and female die. Height of elastic element equals that of female die. Note here that outer surface generating line passes through female die working surface points with maximum and minimum diameters.
EFFECT: better quality of faceting thin-wall axially symmetric tapered parts.
