Abstract


Purpose. The aim of this paper is in investigation of strain-stress state of billet during the forging by asymmetric anvils and determining of them dimensions which provide high level of shear deformations.
Design/methodology/approach. Researches were made by the finite element method. Boundary conditions are the next. Diameter of billet 1000 mm, width of anvils 1000 mm. Relative feed is one. Material of billet is steel with carbon content 0.35%, initial temperature of billet is 1100 0C, of instrument is 20 0C. Heat transfer coefficient is 5 W/m2 0C. Friction coefficient by Zibel law is 0.35, speed of anvils move is 10 mm/sec.
Findings. It is determined influence of tools geometric parameters in forging processes upon to level of shear deformations in billet.
Originality/value. The recommendations of determining the tools parameters and regime of forging process which are provide a high level of shear deformations in billet were given.
