Processing method for optimizing metal surface performance by using high-frequency impact technology

Abstract

The invention discloses a processing method for optimizing metal surface performance by using a high-frequency impact technology. High-frequency vibration is generated by adopting a high-frequency vibration generator, and transmitted to a ball through a transducer and an amplitude transformer, so that the ball generates high-frequency mechanical vibration, the ball impacts the surface of a processed workpiece at a high speed under the action of the high-frequency mechanical vibration, and after continuous impact, the metal surface of the processed workpiece undergoes severe plastic deformation, thereby changing the microscopic appearance of the metal surface; and through high-frequency impact on the metal surface, a metal surface crystal is reshaped, the metal surface crystal defect is eliminated, the lubricating property and the wear resistance of the friction working surface are improved, the running-in period is shortened, the lubricating oil loss is reduced, and the service life ofa product is prolonged. The method also has the advantages of convenient operation, simple process and the like, the processed metal surface roughness quality is high, the processing efficiency is improved, and the method is suitable for large-scale production and processing.

Description

technical field [0001] The invention belongs to the technical field of metal surface processing, and in particular relates to a processing method for optimizing metal surface properties by utilizing high-frequency impact technology. Background technique [0002] Before the 1970s, the industry believed that the smoother the surface of the relatively high-speed frictional movement, the better it would be a mirror surface. Therefore, there were only higher requirements for the smoothness of the relatively frictional surface. For example, the drawings of the inner surface of the cylinder liner only mark the smoothness ▽9. However, there is only a surface like a mirror, no oil storage space, no lubricating oil can be stored, the lubrication conditions are not good, and it cannot adapt to the increase in relative frictional motion speed, which is prone to parts strain, frequent stuck faults, premature parts scrapping and other problems. [0003] In the 1970s and 1980s, in the aut...
