FIELD: machine building.
SUBSTANCE: device for strain hardening of inner surface of through hole part comprises support, at least two deforming elements in form of conic rollers, clamp with hole, in which a gear wheel, gear rim made on one end of supports, thrust and rod threaded part. Taper rollers are adjacent to support and retained against falling out separator. At least one said taper roller is made with annular projection. Support has a through threaded hole, is installed on threaded part of stock with possibility of rotation and axial displacement relative to threaded part of rod by means of rotation transmission with gear wheel rim gear wheel. Stop and holder are arranged between them of machined part. Rod is connected with clamp by means of nuts and hydraulic or pneumatic cylinder to ensure preliminary compression of machined part.
EFFECT: broader technological capabilities.
