FIELD: metal forming.
SUBSTANCE: group of inventions relates to metal forming, particularly, to production of thin-walled tapered metal barrel by means of drawn mug drawing. At that drawing is performed in several stages with reduction of diameter of section with cylindrical wall. After drawing in die for dispensing distribution is performed and height is increased to final height of sleeve.
EFFECT: expansion of technological capabilities due to production of conical sleeve with large inclination of the wall.
