Description

Wheel surface treatment method

technical field

The invention relates to a wheel rim surface treatment method, in particular to a wheel rim surface treatment method for improving production efficiency and reducing production cost.

Background technique

The manufacturing process of the rim is to roughly form the shape of the rim by die-casting or forging, and then perform surface treatment on the rim to make the surface of the rim smooth and then carry out subsequent electroplating. Or coating treatment, in the past, the treatment method of the rim surface was to use artificial methods to polish the surface of the rim with a grinding wheel or a cloth wheel, but the surface of the rim is polished manually, even if it is skilled and experienced Master, the average number of finished products per day is only eight. This is also the main reason why the price of the rim remains high. Secondly, because the rim is polished manually, it is inevitable that there will be mistakes, and the wheel will be worn off if you are not careful. The pattern formed on the rim, or the size of the formed rim is different, resulting in uneven product quality and a high defect rate. Moreover, polishing is to grind and shape the surface of the rim, and the tools used are also relatively dangerous. , if a staff member is accidentally injured, it will definitely not be solved by rubbing medicine on the skin, so the risk is also increased invisibly.

Therefore, after researching on the automatic method of surface treatment of rims, a processing method for aluminum alloy steel rims was developed. The flow chart is shown in Figure 1, which includes in sequence:

A. Chemical cleaning, soak the rim in a cleaning agent containing calcium chloride to remove impurities and soften the rim surface;

B. Coarse shock, place a ceramic grinding stone in the vibrating grinder, add aluminum alloy material cutting potion, and put the rim into the vibrating grinder for grinding;

C. Wash with clean water, take the rim out of the vibrating grinder and clean the surface with clean water;

D. Fine shock, place a plastic grinding stone in the vibrating grinder, add aluminum alloy material cutting cleaning potion, and put the rim into the vibrating grinder for grinding;

E. Clean with clean water, take the rim out of the vibrating grinder and clean the surface with clean water;

F. Chemical polishing, immerse the rim in a medicament containing nitric acid and hydrofluoric acid to remove impurities and bleaching of the rim;

G. Clean with clean water, take the rim out of the vibrating grinder and clean the surface with clean water;

H. Oscillating polishing treatment, placing steel balls or porcelain balls in the oscillating grinder, adding polishing agent, and putting the rim into the oscillating grinding machine for grinding;

I. Clean with clean water, take the rim out of the vibrating grinder and clean the surface with clean water;

J. Drying treatment, drying the rim surface with a tunnel and closed dryer;

K. Plane polishing, manually operate the wheel cloth machine and use wax oil to level the surface of the rim;

L. Ultrasonic cleaning, using an ultrasonic cleaning machine to remove wax oil, impurities and chemicals attached to the rim; and

M. Drying treatment, drying the surface of the rim with a tunnel and closed dryer.

Usually, the automatic method of rim surface treatment can indeed reduce some manual work accidents and risks, and the result of mechanized operation can improve the yield rate of finished rims;

However, if you pay attention, you will find that the methods usually used are actually quite complicated, and there are dozens of procedures that must be handled. There are five steps in each step that must use chemical agents, which is nothing less than serious pollution to the environment, and in order to process the chemical agents used in the five steps, it is necessary to spend a large amount of waste water and waste chemical agent treatment costs. This method It is conceivable how much profit will be left after the east and west deduction. Although the quality and safety have been improved, the production cost has been relatively increased, and there has been no significant increase in production efficiency, so the price of rims remains the same. It is difficult to reduce, so the rim manufacturing industry is still struggling to develop the technology of rim surface treatment until now, hoping to find a rim surface treatment method that can take both into account and reduce the price of the rim.

The inventors of the present invention conducted research and development aiming at improving production efficiency and reducing production cost, and after integrating chemical technology, developed a method for surface treatment of the wheel rim.
