Automotive aluminum wheel coating production line1. Pre-treatment process of automotive aluminum alloy wheel coating production linePre-treatment process is the process of passivation film treatment for the treated aluminum alloy wheels in the coating process. According to the generation of passivation treatment film, it can maintain the wheel rim from environmental pollution such as soil and waste water in the car driving, prevent the leaching caused by the road environmental pollution touching the aluminum alloy wheel hub for a long time in the driving, and improve the service life of the aluminum alloy wheel hub of the car. When carrying out the processing technology of aluminum alloy wheel preparation treatment, the general self-injection type of machine and equipment is selected. By studying past information and practical applications, the author found that pretreatment of automotive aluminum wheels by spray-type equipment can ensure that aluminum alloy wheels can form a comprehensive passivation film more extensively than other pretreatment equipment.2、Grinding process of automotive aluminum alloy wheel coating production lineAt present, the commonly used automobile aluminum alloy wheel grinding equipment mainly includes angle grinder, surface grinder, air grinder, etc. When grinding automotive wheels, it is necessary to choose the appropriate grinding equipment for grinding according to the actual situation of the wheels. For the irregular shape of aluminum wheels and mechanical equipment with pipe grooves, the plane grinding machine can be used to solve the grinding plan, the corner grinding machine can be used to solve the parts with large pipe grooves, and the pneumatic head can be used as the processing equipment to solve the small pipe grooves. After carrying out sanding treatment, the waste produced is easy to make the operator injured, while the range required for sanding equipment is much wider.Wearing the appropriate protective clothing, there are also companies that need to set up special grinders. Before grinding, the wheels must be thoroughly inspected, the exact location and degree of grinding must be determined, and an appropriate construction plan must be drawn up for grinding. After the grinding is finished, the secondary inspection and processing of the automotive aluminum wheels is needed to ensure the quality of the polished equipment, improve the aesthetic appearance and confirm that there are no grooves and protrusions before the painting process.3、Powder spraying process of automotive aluminum alloy wheel coating lineAfter the pre-treatment and grinding process, it is necessary to carry out powder coating treatment on the automotive wheels. The initial formal process of the aluminum alloy wheel coating process is that, by carrying out powder coating operation on the automotive aluminum alloy wheels, it is possible to produce a flat cover by spraying paint to the finished grinding automotive wheels, and at the same time, the thickness of the spray powder is usually chosen to be 100μm when carrying out powder coating treatment, which can improve the wheel's It can improve the aesthetics and corrosion resistance of the wheels, effectively meet the current requirements of the wheels for driving, improve the life of the wheels, and realize the basic guarantee of the driver's life safety.After the powder coating operation of aluminum alloy wheels, the powder coating can review the defects existing on the surface of the wheels and lay a solid foundation for the next coating technology. At present, auto parts manufacturers have realized the assembly line production of powder spraying technology. The specific production line includes thermal energy system, curing oven, chain conveyor, production waste recycling equipment, powder blasting workshop and powder blasting gun. Through the above automated sandblasting processing, can significantly reduce the investment in human resources when sandblasting operation, improve the safety of sandblasting processing.4、Spraying process of automotive aluminum alloy wheel coating production linePainting technology is the last process of the automotive aluminum wheel coating production line technology. By painting the automotive wheels, it can not only improve the aesthetic appearance of the car, but also further strengthen the anti-corrosion ability and anti-stoning ability of the automotive wheels. There are two kinds of paints and varnishes commonly used to carry out the coating treatment. The operating environment of aluminum wheels is not good, and when the painting process is carried out, three painting rooms are usually reserved in the wheel treatment line so that the automotive wheels can be adequately painted and treated.Meanwhile, in order to improve the painting quality of the automotive aluminum wheels after painting treatment, acrylic painting is usually chosen to treat the automotive wheels. By treating the color paint as well as the varnish with acrylic baking paint, it can effectively eliminate the situation of color difference in the wheel painting. There are two main types of painting technology: manual painting and automatic painting. Manual painting requires a high level of operator skill. For manual painting operation, the operator should have sufficient painting experience to ensure that the surface of the aluminum alloy wheel is evenly painted and has a flat appearance after painting treatment.
