According to the type and characteristics of the automobile stamping parts, how to choose the material

When selecting materials, we first choose metal materials with different mechanical properties according to the type and characteristics of automobile stamping, so as to achieve the purpose of ensuring product quality and material saving.

Generally, the following principles should be followed when selecting the material for automobile stamping parts.

The selected materials should first meet the performance requirements of auto parts.

The selected materials should have better technological properties.

The selected materials should have better economy.

A large number of cold stamping processes are used in the production of automobile stamping parts, which are suitable for many varieties and mass production of automobile stamping parts industry. In heavy duty vehicles, most of the panels, such as body panels, and some load bearing and supporting parts, such as frames and cars, are all automotive parts. Cold stamping is mainly for steel sheet and strip steel accounted for 72.6% of the total consumption of the vehicle, the relationship between cold stamping materials and automotive stamping parts production close performance materials not only determine the product, but also directly affect the design process of automobile stamping process, affect the product quality, cost, service life and the organization of production, so the reasonable selection of materials is an important and complicated work.

On the stamping part, in general, the number of the working procedure is the same nature of the process and the number of repeated operations. Therefore, under the premise of ensuring the quality of stamping parts, we should minimize the number of processes, so that we can improve the production efficiency of workpiece and improve its economic benefits. Moreover, this requirement should be strictly enforced, and there can be no carelessness and lax in order to ensure the above effect.

On the stamping part, is the heat treatment strength lower than that before the unheat treatment?

This question, the answer is not necessarily, because its key, or to look at the heat treatment process, mainly heat treatment temperature this one. Generally, after cold stamping, the brittleness of metal will increase. Therefore, the heat treatment or blackening treatment is used to improve the plasticity of the stamping parts. If it is for the low temperature process, then its strength is reduced, but if it is annealed at high temperature, it will not have a great impact.
