Object of research - the technological processes and press tools for low-waste manufacturing of hollow parts as rings and sleeves based on combining the operations division and extrusion. Methods of research - the basis of theoretical studies put the energy method of upper bound and finite element method. Experimental studies were conducted using the method of physical modeling and strain gauges for measuring technological effort and the method of coordinate grids to determine the strain state of preparations. Theoretical and practical results - obtained calculated dependencies allow to describe the deformation mode of the processes forming the hollow parts, developed practical recommendations for calculation of the energy-power parameters of the processes forming the hollow parts as rings and sleeves, are proposed and tested new ways and schemes of tooling to produce hollow billets as rings and sleeves. Novelty - first established influence billet form during piercing on quality forming. The first time determined the dependence between the radial flange forming and quality ring obtained by piercing flange. The first time defined dependence the parameters of the billet deformation during upsetting on the plate with a hole befor the billet piercing from the geometric parameters of plates for upsetting. Efficiency of introduction - results will expand the range and provide savings of material resources in the production of hollow parts. Scope - forging, pressing, stamping.
