Surface processing method for automobile wheel hub

Abstract

The invention discloses a surface processing method for an automobile wheel hub. The surface processing method comprises the following steps of: burying the wheel hub into solid particles with a certain depth, and uniformly spraying liquid containing an alkaline wheel hub cleaning agent on the wheel hub and the solid particles for multiple times; through ultrasonic vibration and mechanical vibration methods, enabling the solid particles and the surface of the wheel hub to generate relative motion, impacting and rubbing the surface of the wheel hub, and thus conducting cleaning, polishing and surface prestress treatment on the wheel hub; and then, flushing and drying the treated wheel hub. According to the method, impurities such as a release agent, greasy dirt and dust on the surface of the wheel hub can be efficiently and thoroughly cleaned; a small amount of burrs on the wheel hub can be removed, the surface of the whee hub is polished, the surface quality of the whee hub is improved, and the subsequent paint baking and electroplating processes are more perfect; and the surface of the wheel hub can be subjected to surface prestress treatment, so that the fatigue performance of the wheel hub is improved, the durability of the wheel hub is improved, the service life is prolonged, and the performance of the wheel hub is enhanced.

Description

technical field [0001] The invention relates to the field of surface treatment of automobile wheel hubs, in particular to a method for processing the surface of automobile wheel hubs. Background technique [0002] In recent years, with the vigorous development of industry, automobiles have been integrated into the daily life of the public and become one of the most common means of transportation for people. As an important part of a car, the wheel hub is also highly valued for its appearance and performance. Wheel hubs are usually manufactured by casting or forging methods. After the blank is formed, some positions are subjected to finishing treatment such as turning and milling. Therefore, a small amount of burrs will remain on the surface of the hub, and impurities such as mold release agents, oil, and dust will remain. In order to realize the subsequent polishing, painting or coating process of the wheel hub, it is necessary to clean the wheel hub. Conventional water sp...

AI Technical Summary

Problems solved by technology

In general production, cleaning, polishing and surface prestressing treatment are three production processes. The actual operation is relatively time-consuming and labor-intensive, but they are all treatment processes for the surface of the wheel hub. Therefore, cleaning, polishing and surface prestressing treatment can be combined. In order to simplify the production process, a method for surface processing of automobile wheel hubs is provided
