Automobile stamping parts are metal stamping parts which constitute automobile parts. They are various, such as spring tray, spring seat, spring bracket, end cover, cover, compression valve cover, compression valve cover, oil seal seat, bottom cover, dust cover, impeller, oil cylinder, support and so on. When selecting materials for automobile stamping parts, firstly, according to the types and characteristics of automobile stamping, metal materials with different mechanical properties are selected to ensure the quality of products and save materials.

I. reasonable material selection

Reasonable selection of materials is an important and complex work. The steel used for cold stamping is mainly steel plate and steel strip, accounting for 70% of the steel consumption of the whole vehicle. The relationship between cold stamping materials and the production of automobile stamping parts is very close. The quality of materials not only determines the performance of products, but also directly affects the process design of automobile stamping parts, as well as the quality, cost and service life of products. Life and production organization.

II. Three principles of material selection

(I) the selected materials shall first meet the service performance requirements of auto parts;

(2) the selected materials shall have good technological performance;

(3) the selected materials shall have better economy.

The main features of stamping parts are as follows:

(1) the finished stamping parts have light weight and good rigidity, and their strength has been improved due to plastic deformation.

(2) it has high dimensional accuracy and is uniform with the size of the module, so it has good interchangeability and can meet the general assembly and use requirements. If there is no special requirements, it can be used directly.

(3) because the surface of the material is not damaged in the stamping process, it can have better surface quality. Then, the surface treatment such as spray painting and electroplating can be carried out conveniently and get good results.

How to maintain stamping parts:

1. Stamping parts are not suitable for packing and storage with chlorine containing polymers and plastic materials.

2. In stamping parts, there is a titanium alloy material, which is not suitable for storage with blister plate, packing box and other items.

3. Among them, the high-temperature alloy stamping parts shall not be in contact with sulfide. In addition, special attention shall be paid to the fact that they shall not be in contact with sodium and sulfur in the air, otherwise, they are easy to be corroded.

4. Do not contact with acid, alkali and other articles to avoid damage.
