All of us are familiar with automotive stamping parts. The use of stamping parts is indispensable in the process of automotive production and processing. Today’s guide mainly introduces the principles and characteristics of automotive stamping parts selection.
What are automotive stampings
Automotive stamping parts, as the name implies, are metal stamping parts that constitute automotive parts. In the automotive stamping parts, one part can be directly made into automotive parts after stamping, and the other part can be made into automotive parts after welding, machining, painting and other processes after stamping. There are many kinds of automotive stamping parts, such as automotive shock absorber stamping parts spring tray, spring seat, spring bracket, end cover, cover, compression valve cover, compression valve sleeve, oil seal seat, bottom cover, dust cover, impeller, oil cylinder, lug, support, etc. are all automotive stamping parts.
Material selection principle of automotive stamping parts
When selecting materials, first select metal materials with different mechanical properties according to the type of automotive stamping and use characteristics, so as to ensure product quality and save materials. Generally, these principles should be followed when selecting materials for automotive stamping parts. The selected materials shall first meet the service performance requirements of auto parts, have good process performance, and have good economy.
Reasonable Material Selection for automotive Stamping Parts
A large number of cold stamping processes have been adopted in the production of automotive stamping parts to meet the needs of multi variety and mass production of automotive stamping parts industry. In medium and heavy vehicles, most of the covering parts, such as body panels, and some load-bearing and supporting parts, such as frames, carriages and other auto parts are auto stamping parts. The steel used for cold stamping is mainly steel plate and steel strip, accounting for 72.6% of the steel consumption of the whole vehicle. Cold stamping materials are closely related to the production of automotive stamping parts. The quality of materials not only determines the performance of products, but also directly affects the process design of automotive stamping parts, and affects the quality, cost, service life and production organization of products. Therefore, reasonable selection of materials is an important and complex work.
Differences between automotive stamping die and metal die
If the stamping dies in automotive stamping parts are compared with the metal stamping dies, there is a difference between the two. For the former, many of them have the technical requirements of side A, while for the latter, there is no such requirements. Therefore, this conclusion can be drawn. Therefore, the difference between the two is mainly in the technical requirements.
Characteristics of automotive precision stamping parts
The finished automotive precision stamping parts have light weight, good rigidity and high strength. In the stamping process, the surface of the material is not damaged, so it can have good surface quality. And then paint, electroplating and other surface treatment can be carried out to obtain better effect, oxidation resistance, corrosion resistance, beautiful and smooth. It has high dimensional accuracy, and the same size as the module is uniform. It has good interchangeability and can meet general assembly and use requirements. It can be used directly without special requirements.
Conclusion
The material selection of automotive stamping parts is very important, which is related to the quality of automotive parts. Only by understanding the material selection principles of automotive stamping parts can the best stamping parts be made.
