FIELD: process engineering.
SUBSTANCE: invention relates to tube billet flange rolling-off. Blank is subjected to rotary swaging by roller arranged at the angle 25°<β1<30° to blank axis to form truncated cone at its deformable part. Truncated cone section abutting on its base is deformed by forced displacement of the roll located at 8°<β2<12° to blank axis to form preliminary flange. Preliminary flange is deformed to strain-free section of truncated cone by forced displacement of the roller located at 50°<α<70° to blank axis.
EFFECT: expanded performances.
