FIELD: metal forming.
SUBSTANCE: invention relates to metal forming and can be used for drawing of cylindrical shells from sheet metals with plane anisotropy of mechanical properties. Removable ring with shaped smoothly conjugated cone cavity is fixed on puncheon-matrix. Ring is fixed taking into account the direction of formation of festoons in the cylindrical shell.
EFFECT: elimination of festoon formation during drawing cylindrical shells.
