METHOD OF SURFACE PLASTIC DEFORMATION OF COMPLEX-SHAPE SURFACES BY ELECTRIC HARDENING HEAD Russian patent published in 2011 - IPC B24B39/04

Abstract RU 2420391 C2

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming, particularly, to rotary drawing of cylindrical shells, hollow articles and, to static pulse spinning. Billet and deforming tool are driven to revolve about their axes. Deforming tool is used that comprises body made up of three-phase induction squirrel-cage motor with rotor running in antifriction bearing there inside. Rotor bore surface is provided with race for deforming elements to be arranged thereon. Body is pivoted on aforesaid support to perform reciprocating oscillations there across. Compression spring secured on the support is used to preset surface plastic deformation.

EFFECT: expanded performances, higher efficiency and quality.
