FIELD: metallurgy.
SUBSTANCE: invention relates to the metal deformation process and can be used in aircraft and power industry at manufacturing of disks of rotors of gas turbine engines and rotors of turbines of heating and atomic power plants. It is implemented moulding of drafts of stand Then it is implemented forming of blank by means of its distribution and unfolding of wall into flat ring. Wall of sleeve is formed with increasing of thickness from bottom to edge of stand. For disk with rim it is received with flange on wall of sleeve. After moulding it is implemented drawing out on mandrel of sleeve wall. After distribution and unfolding of blank it is implemented final calibration in punch.
EFFECT: ability of receiving of disks from different steels and alloys with specified physical-mechanical properties and structure.
