How to repair the out-of-roundness of Volvo aluminum alloy wheels

How to repair Volvo aluminum alloy wheels is a high-tech enterprise in my country that focuses on the research and development, design, production and sales of aluminum alloy wheels, and an export base of auto parts in my country. Office), the geographical position is superior and the transportation is convenient. The company covers an area of ​​120 mu, with a registered capital of 118 million yuan, total assets of nearly 180 million yuan, and more than 300 employees. It has 11 authorized inventions, 18 utility model patents, and 40 design patents. The company's stock was listed on the New Third Board on August 12, 2016. The stock code is 838269. The stock is referred to as "Technology". Special new "small and medium-sized enterprises, provincial high-tech cultivation enterprises.

We all know that less unsprung weight leads to better car performance, better acceleration and braking, and better fuel efficiency. The hollow design greatly reduces the weight of the car hub, and the aluminum alloy also provides sufficient strength for the spokes to support the rim. This is why many car owners want to replace forged wheels.

Because the forged wheels are not only good quality, but also light weight. Of course, the hollow design saves the aluminum alloy material used in the manufacture of the wheel hub, reduces the production cost of the wheel hub manufacturer, naturally reduces the cost, and consumers also enjoy benefits. How to repair Volvo aluminum alloy wheels out of round Ability; the company has a complete and scientific quality management system.

The company's integrity, strength and product quality have been recognized by the industry. Taking quality as the core, adhering to the business philosophy of "internationalization, branding, and scale", it is committed to "continuous improvement, pursuit of high-quality products, improvement of service quality, and satisfaction client needs". The material development of ordinary automobile wheels is not ordinary pig iron, but steel with a carbon content of 2.0% or less; but the proportion of pig iron is as high as 2.0% to 4.5%, so in mechanical design, there is a big gap between the strength and toughness of the two different materials . However, even steel is not very strong.

For example, body A-pillars made of hot-formed steel with a yield strength of up to 1,500 MPa may still bend in a crash. Therefore, the compression ability of the steel wheel hub is relatively weak, that is to say, it is relatively simple and easy to deform. Volvo Aluminum Alloy Wheel Out of Round How to Repair Company was founded in 2011. After more than seven years of development and operation, the company has become a large-scale enterprise in the domestic aluminum alloy wheel industry with product serialization, large-scale production, and brand management.

The green and milky white of car wheels are two contrasting colors, and the red of taillights is a good choice for red and black; so men try to choose black, because black represents stability and fierceness without losing the true color of tires. If you want to keep the original color for a long time, you should choose the change of painting color, it is recommended to go to a reputable modification shop. It's not as simple as we thought.

First of all, the surface of the car hub is leveled and repaired, then cleaned and painted, then dried at high temperature, and installed after 5 days. Be careful not to touch sharp and hard objects when driving, and remind workers not to scratch when washing the car. Aluminum alloy wheels are more suitable for passenger cars than steel wheels. At present, their manufacturing processes can be divided into three categories.

The first is casting, which is the process of choice for most car manufacturers today. Low-pressure casting is a process in which molten aluminum is filled into a mold under pressure and solidifies and crystallizes under pressure. In the same situation, compared with gravity casting, the internal structure of low-pressure casting hub is denser and stronger.

At present, low-pressure casting has become a process for producing aluminum alloy wheels, and most domestic aluminum alloy wheel manufacturers use low-pressure casting. When the vehicle is moving forward, it presses down on a hard, sharp object that is higher than the distance between the outer edge of the car's wheel hub and the ground, and is located on the outer edge of the tire. When the tire was pressed against the object, the sharp corner of the object just hit the outer edge of the tire, piercing the fragile outer edge of the tire (this would explain the radial fracture of the tire).

After a tire blows out, it immediately loses its cushioning ability. A hard object hit the hub directly, causing the hub to break near the edge of the valve (this would explain the defect in the edge of the hub). It then causes the entire hub to break.

Or when the hub encounters a large pit, it will pass quickly, exceeding the bearing range of the hub, resulting in fracture. How to repair the out-of-roundness of Volvo aluminum alloy wheels? Make color preparations according to the original color of the wheels, and choose different types of sandpaper for grinding according to different damage degrees. We need to repaint the car wheels. But before painting, we tried to use waste newspapers to isolate the edge of the wheel hub to prevent the spray paint from splashing on the tires.

Put it in the equipment at 100-120℃ to dry for 60 minutes, then grind it again to a matte finish. If it still feels a little hairy, you can continue to smooth it with sandpaper. Cover the rim with a universal shielding film, wipe the surface of the rim with a degreaser, dry it with equipment, and wipe the surface dust with a dustproof cloth.
