IMPACT DEVICE FOR HARDENING METALS BY SURFACE PLASTIC DEFORMATION Russian patent published in 2017 - IPC B24B39/06 

FIELD: metal processing.

SUBSTANCE: invention relates to impact device for hardening of metal articles by surface plastic deformation. Impact device comprises carriage, a base on which a working cylinder with a deforming tool is mounted, connected to drive of impact action, and mechanisms of static loading of deforming tool and horizontal movement of deforming tool. Mechanism for static loading of deforming tool is made with possibility of vertical movement of deforming tool. Base is made in form of two frames, one of which is connected with mechanism of horizontal movement of deforming tool and slides on carriage, and other one – with mechanism for static loading of deforming tool and moves in vertical plane relative to first one. Drive of impact action is electropneumatic. Mechanism for static loading of deforming tool and mechanism for horizontal movement of deforming tool are made in form of a screw pair.

EFFECT: result is high-quality hardened article.
