Description

technical field [0001] The invention relates to the field of metal processing equipment, in particular to a high-frequency direct current heating auxiliary rolling processing device and a processing method thereof. Background technique [0002] Rolling is a process of locally and continuously pressing the surface of a part with a high-hardness and smooth surface, causing the surface of the part to undergo plastic deformation and generate compressive residual stress and cold work hardening, thereby achieving mechanical surface strengthening of the part. The method can improve the wear resistance, fatigue resistance and corrosion resistance of parts, and is of great significance to prolonging the service life of metal parts and ensuring more reliable and safe operation of mechanical equipment. [0003] With the development of the times and science and technology, for the surface strengthening of some special materials (high hardness), the simple rolling surface strengthening t...
