FIELD: plastic working of metals, possibly low-waste processes for shaping elongated forged pieces, mainly nut wrenches.
SUBSTANCE: method comprises steps of heating initial blank and subjecting it to preliminary profiling during transverse taper rolling by means of flat tool at temperature of semi-hot deforming; performing additional heating of rolled blank till temperature of hot deforming in combination with preliminary profiling; then forming forged piece in closed die set in hot deforming mode. Additional heating of rolled blank may be realized due to changing deformation modes of transverse taper rolling causing heating of blank.
EFFECT: lowered power consumption for heating blank, improved quality of forged pieces.
