FIELD: rotary plastic working of materials, possibly forming beads on tubular blanks.
SUBSTANCE: method comprises steps of imparting rotation to blank; providing tool rotation simultaneously with rotation of blank due to contact friction between tool and blank; performing local deformation of blank by means of deforming tool in the form of roller; placing roller with possibility of rotation and turning relative to blank axis; performing deformation by two stages; at first stage performing rotary upsetting of blank by means of roller by angle 15 - 40° relative to blank axis for forming truncated cone; at second stage deforming truncated cone by positive motion of roller by angle 40 - 75° relative to blank axis.
EFFECT: enhanced mechanical properties of article, lowered cost of working blank for deforming, enlarged manufacturing possibilities of method.
