FIELD: plastic metal working.
SUBSTANCE: method comprises setting the blank in the mandrel provided with the cylindrical and shaped sections, locking the blank in the cylindrical section of the mandrel, and affecting the blank by deforming rollers. The shaped section is initially formed by moving the rollers in different trajectories during one or several runs. Upon unlocking the cylindrical section, the blank is locked in the shaped section and the cylindrical section is drawn by moving the rollers in the opposite direction.
EFFECT: expanded function capabilities.
