Aluminum wheel finishing process

Abstract

The invention discloses an aluminum alloy wheel finishing process, which comprises the steps of: aslant pouring and immersing aluminum alloy blank subjected to thermal processing in a rotating container filled with a grinding material and a grinding agent, forming a medium flow in the front of the wheel through the rotation of the wheel and the relative movement of the container, and carrying out regular and efficient grinding and polishing processing on the front of the wheel and window parts by the medium flow, and finally realizing a mirror polishing effect with extremely excellent surface consistency. By adopting the process, the problems of poor appearance quality in tradition mechanical polishing and low efficiency of a vibration finishing process are overcome, the labor intensity of workers is greatly reduced, the labor environment of the workers is improved, the efficiency is 5-6 times that of the tradition polishing process and vibration finishing, and great cost advantage is achieved.

Description

technical field [0001] The invention relates to an aluminum alloy wheel polishing process. Background technique [0002] After more than ten years of development, the polishing process of aluminum alloy wheels has gradually realized the transition from manual mechanical polishing to mechanical automation abroad. The typical processing methods are mainly robot polishing and vibration polishing. Although robot polishing has high processing efficiency, However, due to the obvious constraints of wheel shape and product diversity, the surface consistency and brightness are poor, the yield is low, and it is difficult to eliminate the surface defects remaining in the process of casting and forging blanks; However, due to low processing efficiency and low production capacity, it is difficult to meet the growing demand for polishing orders.

[0002] After more than ten years of development, the polishing process of aluminum alloy wheels has gradually realized the transition from manual mechanical polishing to mechanical automation abroad. The typical processing methods are mainly robot polishing and vibration polishing. Although robot polishing has high processing efficiency, However, due to the obvious constraints of wheel shape and product diversity, the surface consistency and brightness are poor, the yield is low, and it is difficult to eliminate the surface defects remaining in the process of casting and forging blanks; However, due to low processing efficiency and low production capacity, it is difficult to meet the growing demand for polishing orders

[0003] At present, in the polishing of automobile wheels in our country, workers generally hold the wheel and perform fine polishing on the grinding wheel driven by the motor. The labor intensity of the workers is very high, and the requirements for the proficiency of the workers are relatively high; On average, only 2 to 3 wheels can be processed every day. Taking a manufacturing enterprise with a monthly output of 20,000 wheels as an example, 300 workers are employed in the process of wheel polishing, which takes up a considerable area of ​​factory buildings for processing. ;Due to the large amount of dust generated during the grinding process, the infiltration of the respiratory tract and the skin into the worker's body will cause great harm to the health of the worker and also cause great damage to the local environment; the surface polishing of the wheel is due to the complexity of the wheel surface Due to the diversity of wheel products, the overall surface consistency of the traditional polishing process is extremely poor, and the polishing gloss and overall surface quality are difficult to meet the required standards; The original and backward processing method of polishing has become the biggest bottleneck in the promotion and development of my country's automobile wheel production industry
