APPARATUS FOR STRENGTHENING-FINISHING PARTS BY ROLLING OUT Russian patent published in 2002 - IPC

FIELD: material working, namely, strengthening-finishing parts by plastic deformation of their surface, possibly in different branches of machine engineering. SUBSTANCE: apparatus includes housing, step drive mechanism, control unit. Deforming roller is mounted onto spherical articulation joint that is movably mounted on pin between two elastic members. Roller is kinematically joined by means of shackle with linear- motion step drive and it may perform rocking motion relative to plane normal to part axis at periodically shifting contact zone of working surface and part surface. Due to use of elastic members roller may in addition perform reciprocation motion parallel relative to its main motion to side of drive action. EFFECT: possibility for forming regular microrelief in the form of annular grooves of crossing waves with predetermined amplitude and changing formed microrelief at operation. 2 dwg
