The expediency of a combination of operations of preliminary upsetting and drifting of billets outside of dies’ gravures with operations of consequent completing die-forging by manufacture of axisymmetric forgings is justified. Operations can be executed on the different equipment, thus necessity of the account of regularities of buckling of billets is shown at a preparatory upsetting before consequent die-forging transitions. The generalized technique of designing of technologies of the combined die-forging of the axisymmetric forgings, taking into account regularities of a form-changing on operations of a upsetting and drifting is offered. The industrial introduction of more perfect technology of the combined hot volumetric die-forging of the forging-part “the Head of an oxygen nozzle” is executed, allowed to save up to 7,7 % of a technical copper on each workpiece.
