FIELD: machine building.
SUBSTANCE: invention relates to machine building, particularly, to metal treatment under pressure, and can be used for spherical parts with flat bottom drawing. Male die is made with transition section connecting end flat part and side spherical part, in form of curvilinear generatrix with monotonically increasing radius of curvature.
EFFECT: reducing part wall thinning and breaking, reducing process transitions.
