FIELD: metal forming.
SUBSTANCE: invention relates to metal forming and can be used in production of metal cans for non-carbonated and carbonated beverages. Punch (1) for making a can is made in the form of a cylindrical body having axis (4) of symmetry, smooth outer surface (2) and end part (3). End part (3) has annular projection (5). Contour of annular projection (5) vertex in punch (1) longitudinal section by plane, in which symmetry axis (4) lies, is formed by the first and second arcs. Arcs are conjugated with a straight section connecting them. Punch (1) is used in production of can to form its body and bottom by drawing a workpiece in the form of a cup.
EFFECT: reduced load on the punch, increased wear resistance at maintaining the required strength characteristics and critical for stacking geometric dimensions of the can produced with the help of this punch.
