Abstract
A metal shaft press polish device comprises a hard alloy pinch roller, a center shaft, a nut, and a body rack, the metal shaft press polish device is characterized in that, the hard alloy pinch roller is connected with the body rack and then installed in the center shaft, and the center shaft is fixed by the nut. A rolling technology is adopted to apply pressure upon the surface of a component in the state of normal temperature, plastic deformation is generated on a metal surface, the microscopic geometrical shape of the component surface is corrected, surface fineness is improved, also metal organizations at the component metal layer are changed, thereby powerful pressure distribution, and improving fatigue strength, durability and hardness of the component. The metal shaft press polish device is mainly applied in lathe rolling, particularly rolling of cylindrical or conical internal and external surfaces, etc., and durability, hardness, and fineness of the rolled metal are improved.
Description
Technical field
