Living conditions are getting better and better, and every household has bought a car. But in daily life, cars are bound to bump on the road, especially those with poor reversing skills. In addition, the weather has had a great influence in recent years. When the flight billboard was parked, it was accidentally hit by a falling object, and the owner was distressed. However, the body frame is not injured, but slightly deformed, and the beauty can be restored only by sheet metal.

1. What is sheet metal?

The so-called sheet metal is actually a processing technology. So far, a complete definition of sheet metal has not been given. In some foreign journals, sheet metal is defined as the processing technology of sheet metal, including various processing technologies. The remarkable feature is to let

Finally, the thickness and shape of the metal plate become consistent.

Second, how to repair automotive sheet metal?

The so-called automotive sheet metal is a technical means to repair the metal plate on the automobile surface. By repairing the metal plate, the dent caused by collision or accident can be repaired. Not only can the car body be sprayed with anti-corrosion and decoration, but also the whole car body can be reshaped, stretched and corrected, stress-relieving welded or the car body accessories assembled and adjusted. The deformation position of the metal plate is restored to its original shape mainly through personnel strength and mechanical equipment.

3. What steps has automotive sheet metal taken?

When you are in automotive sheet metal, you should first mark the parts that need to be repaired due to vehicle collision or accident, observe their deformation, determine the damage, whether the tools used in the sheet metal process need to be used, whether the cracks on the vehicle appearance are seriously damaged, whether it can be repaired without disassembly, or whether the repaired parts have signs of cracks or even fractures. If there are cracks or fractures, replace them and try not to repair them. After determining the repaired parts, it is necessary to refer to the technical parameters and overall dimensions of the car body, and carry out stretching and flat welding processes according to the characteristics of car body materials, stress characteristics and the direction of deformation force. On this basis, we should not only rely on advanced work experience, but also rely on accurate instruments to judge. After the car body is restored to its original state, it is necessary to further treat the paint surface at the damaged position and spray color matching paint to finally restore the car body to its original state and appearance.

As can be seen from the above aspects, automotive sheet metal's steps are to determine the repair parts first, and then repair the damaged parts of the sunken parts according to the measured data. After the repair, color matching, painting and paint surface adjustment will be carried out.
