FIELD: process engineering.
SUBSTANCE: invention relates to metal forming. Proposed method comprises placing workpiece in female die cavity on sphero-dynamic fluctuation module to rest on pusher so that workpiece is strained over its height on revolving and swinging reeling male die axially. Male die is topped after one complete revolution. Thereafter, workpiece is subjected to swaging by 25-35% of its height by vertical displacement of pusher. Final straining is performed by rolling with reeling male die.
EFFECT: higher quality of material structural state.
