  • How to deal with the exterior layer of automobile sheet metal correctly?

    2020-05-26 17:02:21
    Many car owners think that the body parts still need to be painted with the same color as the original car, so they will ignore the painting process of the body parts when choosing the body parts, which is irrelevant, but this idea is not correct. In order to prevent oxidation and corrosion, the body parts need to be painted before leaving the factory. Indeed, the painting link after replacing the body parts can not only color them, but also protect and prevent oxidation. However, if it is a small factory body parts, the painting treatment during production has uneven adsorption and foaming, which will affect the effect of post painting In the process of using, it is easy to fall off, lead to corrosion, affect and damage the quality of sheet metal parts.
  • What are the characteristics and modeling requirements of auto parts sheet metal parts?

    2020-05-19 11:32:53
    Automobile sheet metal parts is a processing method of automobile maintenance, also called cold work. Say directly, if the exterior of the car body is damaged or deformed, the process of sheet metal is needed to restore the original appearance. The basic tool is a hammer. Hammers with different shapes are padded with iron blocks at the back of the sheet metal parts, which are hammered repeatedly to form. Appearance restorers are also used when necessary.
  • What is the basis of automobile sheet metal processing?

    2020-05-12 11:29:40

In the whole cycle of design, manufacture and commissioning of model design mould, mould design, manufacture and commissioning takes about 2 / 3 of the time, which becomes the main factor restricting the transformation of automobile. This is because sheet metal stamping process is a very complex plastic forming process, many factors directly or indirectly affect the forming results.
  • Do you know the basic principles of the route setting of automobile sheet metal parts?

    2020-05-05 11:26:48
    Sheet metal parts are thin and easy to form, which can be formed into parts of various shapes. With the application of welding, assembly, riveting and other processes, it is possible to realize multi structure products. At the same time, these characteristics also make sheet metal parts in the process of processing will more or less occur different degrees of deformation, such as bending deformation, torsion deformation, concave convex deformation and so on. These deformations make the size or shape of the whole component change, resulting in quality problems. However, the production process of sheet metal parts has its own rules. For the same type of products, according to the existing equipment, manpower, etc., the sequence of processing can be flexibly adjusted to give a reasonable processing process. So choosing the right process route is an effective measure to prevent and solve this kind of problem.
