What are the reasons for the difficulty in manufacturing automotive stamping parts?
2023-04-18 08:42:39

1. Surface quality of automotive stamping parts

Any defects on the surface of automobile body stamping parts will affect the beauty of the product, so the surface of automobile stamping parts is not allowed to have defects. Automotive stampings require clear and smooth decorative ridges, uniform transitions and symmetry between left and right, and the connection of ridges between stampings outside the car body must be smooth. Stamping parts not only need to meet the structural and functional requirements, but also must meet the requirements of surface quality.

2. The overall size and shape of automobile stamping parts

The shape of stamping parts of automobile body is mostly three-dimensional. It is difficult to accurately make its size and shape in stamping parts of automobile body. Therefore, the external dimensions of stamping parts of automobile body are generally determined by means of the master model. The position, shape and size of various holes, and the shape of the three-dimensional surface must be consistent with the main model, and the dimensions that cannot be marked on the stamping parts of the automobile body must be measured through the main model. Due to the complex shape, it is difficult to control the springback of the material , increasing the difficulty of controlling the accuracy of product dimensions.

3. Strength and rigidity of automobile stamping parts

During the deep drawing of automobile body stamping parts, the rigidity of certain parts is usually poor, causing partial sinking of the product. Moreover, when the automobile body stamping parts with unsatisfactory strength and rigidity are vibrated, a hollow sound will be produced. If such automobile body stamping parts are assembled into a car, and the car will vibrate when driving at high speed, it will seriously reduce the quality of the car body. The life of stamping parts.

4. Processing technology of automobile stamping parts

The structural shape and size of automobile body stamping parts determine the complexity of the process. It is impossible to process them directly in one process, and at least three processing processes are required. However, the spatial curved surface shape of automobile body stamping parts and the bosses, ribs and ridges on the curved surface should be formed by one-time drawing as much as possible, otherwise it is difficult to ensure the smooth surface and geometrical consistency of automobile body stamping parts.

Automobile stamping parts technology is developing in the direction of precision, multi-functional, high-efficiency, energy-saving, safe and clean production. The manufacturing process level and quality of stamping parts have a direct impact on the quality and cost of automobile manufacturing to a large extent.
