FIELD: technological processes.
SUBSTANCE: invention relates to tooling for metal forming, particularly, to puncheons with curvilinear profile for first transition at two-junction drawing of thin-wall shells of revolution with curvilinear surface. Maximum diameter of puncheon makes 0.9–0.95 of the maximum diameter of the bottom and has the shape of a body of revolution with a curvilinear generatrix.
EFFECT: homogeneous structure and equal thickness of the material produced in the process of shell drawing.
