1. Способ изготовления головок торцовых ключей со ступенчатой наружной поверхностью, заключающийся в отрезке цилиндрической заготовки и последующем ее деформировании по позициям, отличающийся тем, что наружную ступенчатую поверхность предварительно оформляют на второй формообразующей позиции, затем заготовку переносят параллельно на третью позицию и со стороны торца меньшего диаметра выдавливают одну из полостей многогранного рельефа, а на четвертой позиции заготовку опирают дном ранее полученной полости на поддерживающий цилиндрический пуансон и выдавливают другую полость многогранного рельефа со стороны торца большего диаметра, причем выдавливание начинают после упора ступеньки наружной поверхности заготовки на плечики матрицы, при этом продолжают оформление наружной поверхности заготовки, а ее размеры, получаемые на этой позиции, определяют из условия
Figure 00000001

где F - площадь поперечного сечения полости, выдавливаемой на четвертой позиции;
D - больший наружный диаметр заготовки;
d - меньший наружный диаметр заготовки;
d1 - диаметр поддерживающего цилиндрического пуансона.1. A method of manufacturing the heads of the socket wrenches with a stepped outer surface, consisting in a segment of a cylindrical workpiece and its subsequent deformation by positions, characterized in that the outer stepped surface is pre-formed at the second forming position, then the workpiece is transferred parallel to the third position and from the side of the smaller one of the cavities of a multifaceted relief is extruded from the diameter, and in the fourth position, the workpiece is supported by the bottom of the previously obtained cavity on the supporting cylinder cal extruded core and the other polyhedral cavity relief from the larger diameter end, the squeezing is started after the stop of the outer surface of the workpiece at step hanger matrix, while continuing execution of the outer surface of the blank, and its size is obtained at this position are determined from the condition
Figure 00000001

where F is the cross-sectional area of the cavity extruded in the fourth position;
D is the larger outer diameter of the workpiece;
d is the smaller outer diameter of the workpiece;
d 1 - the diameter of the supporting cylindrical punch. 2. Способ по п. 1, отличающийся тем, что на четвертой позиции момент упора ступеньки наружной поверхности заготовки на плечики матрицы совпадает с моментом соприкосновения поддерживающего пуансона с дном ранее полученной полости. 2. The method according to p. 1, characterized in that in the fourth position the moment of abutment of the step of the outer surface of the workpiece on the shoulders of the matrix coincides with the moment of contact of the supporting punch with the bottom of the previously obtained cavity. 3. Способ по п. 1, отличающийся тем, что на четвертой позиции момент упора ступеньки наружной поверхности заготовки на плечики матрицы совпадает с моментом окончания внедрения на заданную величину поддерживающего пуансона в дно ранее полученной полости. 3. The method according to p. 1, characterized in that in the fourth position, the moment of stop of the step of the outer surface of the workpiece on the shoulders of the matrix coincides with the moment of completion of the introduction of a given amount of the supporting punch into the bottom of the previously obtained cavity.
