FIELD: process engineering. ^ SUBSTANCE: invention relates to metal forming, in particular, to surface plastic deformation. External head comprises body, deforming elements and a hollow-shaft rotor. Said body is made up of three-phase induction squirrel-cage motor stator accommodating aforesaid rotor. Deforming elements are arranged inside the rotor, in its bore, and on one end of L-bent plate springs. Plate springs have their other end rigidly secured onto rotor end face. Deforming elements make external elements of the workpiece. ^ EFFECT: expanded operating performances, higher efficiency. ^ 5 dwg |
