Abstract
The invention discloses an induction heating auxiliary surface ultrasonic rolling device and method. The device comprises a lathe chuck, a running center and a lathe cutter holder, the surface ultrasonic rolling device further comprises an induction coil, a movable arm, an induction power source and an infrared temperature measuring gun, one end of the movable arm is used for mounting of the induction coil, the other end of the movable arm is fixed to the lathe cutter holder, the surface ultrasonic rolling device is fixed to the lathe cutter holder, the induction heating power source is turnedon, meanwhile, a lathe is started, a part rotates, a part in the induction coil work area is heated to the high temperature, in the whole process, the temperature is measured through the infrared temperature measuring gun, when a sample is heated to the needed temperature, the part is subjected to surface ultrasonic rolling machining, through induction heating, the part deforming resistance is reduced, the surface ultrasonic rolling machining effect is better, the device is simple in structure, convenient to use, economic and environment-friendly, and the device can be used for machining shaft parts with high machining hardness and poor surface quality.
Description
technical field [0001] The invention relates to the field of metal surface processing, in particular to an induction heating assisted surface ultrasonic rolling device and method. Background technique [0002] Ultrasonic surface rolling process (USRP) is a new surface modification processing technology, which combines ultrasonic vibration with traditional surface deep rolling technology. Plastic deformation makes the surface of the material nano-scale, while increasing the hardness, it also introduces a higher residual compressive stress on the surface of the part, and can also greatly reduce the surface roughness, thereby improving the mechanical properties of the material, improving the corrosion performance of the part, friction and wear performance and fatigue performance. [0003] However, with the development of science and technology, in some special working conditions (high temperature environment, corrosive medium and high stress, etc.), conventional surface ultras...
