Car aluminum wheel coating production line
1. Car aluminum alloy wheel coating production line in front of processing process
The pre-processing process is to process the process of processing the aluminum alloy wheels during the spray painting process with passivation film. This passivation film can protect the wheels from environmental pollution such as soil and waste water during driving, and can prevent the corrosion caused by the environmental pollution of the road surface for a long time during driving, thereby extending the service life of aluminum alloy wheels. During the preparation of aluminum alloy wheels, the universal self-spray mechanical equipment is selected. Through the research and practical application of previous data, the author found that the use of spraying equipment pre -processing the car aluminum wheels can ensure that the aluminum wheels form a comprehensive passivation film, which is wider than other pre -processing equipment.

2. Car aluminum alloy wheel coating production line polishing process
At present, the grinding equipment commonly used in automotive aluminum alloy wheels mainly include corner-oriented grinding beds, plane grinding beds and pneumatic grinding machines. When grinding the car hub, you need to choose the appropriate grinding equipment according to the actual situation of the wheel hub. For mechanical equipment with irregular gutter shapes and tube grooves, you can use plane to solve it when grinding. When there is a large tube groove, you can use angle grinders to solve it. When solving the small tube groove, you can use the pneumatic head as a processing equipment. The waste generated after grinding is easy to harm the operator, and the scope of application of grinding equipment is wider.
Wearing the corresponding protective clothing, companies need to set up a special grinding machine. Before polishing, you need to conduct a comprehensive inspection of the car hub, determine the specific location and degree of polishing, and formulate a suitable polishing construction plan. After polishing, the aluminum wheels of the car need to be performed twice to ensure the quality of the equipment after polishing, improve the appearance of the appearance, and confirm that there are no grooves and raised before spraying.
3. Car aluminum alloy wheel coating production line powder spraying process
After pre-processing and polishing, spraying powder on the car hub. The initial formal process of spraying aluminum alloy wheels in the powder spray treatment is spray paint on the ground car’s car hub to make a flat cover. At the same time, the thickness of powder spraying is usually 100 μm, which can improve the aesthetics of the wheel hub and the anti-stone impact corrosion capacity, effectively meet the current requirements of the car’s wheels, improve the life of the wheel hub, and achieve the basic guarantee of the driver’s life safety.
After the aluminum alloy wheels are sprayed, the powder spray can cover the defects on the surface of the wheel hub, laying a solid foundation for the next coating process. At present, automotive parts production enterprises have realized assembly line production of powder spray technology. Specific production lines include thermal energy system, curing furnace, chain conveyor, production waste recycling equipment, spraying workshop, and powder spray gun. Through the above-mentioned automated sandblasting treatment, the investment in human resources in sandblasting operations can be greatly reduced and the safety in sandblasting treatment can be improved.
4. Painting process of automotive aluminum alloy wheel hub spray production line
The coating process is the last process of the car aluminum wheel coating production line process. By painting car hubs, it can not only improve the appearance of the car, but also further strengthen the anti-corrosion capacity and anti-stone capacity of the car hub. Paint treatment is commonly used for paint and varnish. The environment of aluminum alloy wheels is not good. When spraying paint, three paint rooms are usually reserved on the wheel processing production line, so that the car hub can be comprehensively sprayed.
At the same time, in order to improve the coating quality of the car aluminum wheels, the acrylic coatings are usually selected to treat the car wheel. Use acrylic paint to treat paint and varnish, which can effectively eliminate the color difference between the hub spray paint. There are two main types of painting technology: manual painting and automatic painting. Handmade painting requires higher requirements for operators. For hand-spray paint operations, the operator should have sufficient paint experience to ensure that the surface of the aluminum alloy wheels is sprayed evenly and the appearance of the paint is flat.
