What are the main factors that make the manufacturing of automotive stamping parts difficult?

1. Surface quality of automotive stamping products

Any defects on the surface of the stamped parts of the automobile body will affect the aesthetics of the product, so the surface of the stamped parts of the automobile is not allowed to have defects. Automobile stamping parts require that the decorative ridges are clear, smooth, uniform in transition and symmetrical from left to right, and the ridgeline connection between the stamping parts outside the automobile body must be smooth. Stamping parts not only need to meet the structural and functional requirements, but also the surface quality requirements.

2. Overall size and shape of automobile stamping parts

Most of the shapes of auto body stamping parts are three-dimensional shapes. It is difficult to accurately make the size and shape of the auto body stamping parts. Therefore, the main model is generally used to determine the overall dimensions of the auto body stamping parts. 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 very complex shape, the rebound of the material is difficult to control. , which increases the difficulty of controlling the accuracy of product dimensions.

3. Strength and rigidity of automotive stamping parts

When the stamping parts of the automobile body are deep-drawn, the rigidity of some parts is usually relatively poor, causing the product to sink locally. Moreover, the automobile body stamping parts with unsatisfactory strength and rigidity will produce a hollow sound when they are vibrated. If such automobile body stamping parts are assembled into a car, and the car will vibrate at high speed, it will seriously reduce the automobile body. The life of stamping parts.

4. Processing technology of automobile stamping parts

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

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