Zusammenfassung:	FIELD: metallurgy. ^ SUBSTANCE: it is heated punched section of initial blank and implemented head punching per several passages. During punching initial blank is clutched in half-matrixes. At the first passage it is punched head in the form of two cones, joined by major foundations. At the second passage received semi-finished product at first clutched by half-matrix in places of cones coupling. Then head is punched in the form of cylinder with axis, perpendicular to longitudinal axis of initial blank. Cylinder height is defined equal to 0.8/0.9 of major foundation diameter of cones. At the last passage it is finally punched head in the form of bowl. ^ EFFECT: reduction of making cycle time with simultaneous improvement of received blank. ^ 4 dwg, 1 ex
