In metal technology, corresponding to hot working, cold working refers to the processing technology that can cause plastic deformation of metal below the recrystallization temperature, such as cold rolling, cold drawing, cold forging, stamping, cold extrusion, etc. Cold working has great deformation resistance. While forming metal, work hardening can be used to improve the hardness and strength of the workpiece, but it will reduce the plasticity. Cold working is suitable for processing metal auto parts with small section size and high requirements for machining size and surface roughness.

Automobile stamping parts indicate that due to the importance of products, their quality requirements are very high in many cases, so stamping parts suppliers are the key to product quality assurance. First of all, it depends on whether the stamping parts manufacturer is regular. Second, it depends on whether the products it produces meet various quality and performance standards. Second, it depends on the service it provides.

If the hot stamping forming process is used for automobile stamping parts, the benefits it can bring are mainly to realize the lightweight production of automobiles, and to effectively improve the strength of stamping parts. Moreover, it is molded at high temperature, so it has the advantages of high molding accuracy, high molding performance, etc., and there is no springback problem. The auto parts that can be used are the anti-collision beams, safety parts and car body structural parts.

Repairmen must remove welding slag and glue, and then clean the surface of the body. In particular, exposed metal surfaces must be sprayed with anti-corrosion materials. After the body restoration work is completed, it needs to be assembled. Assemble the trimmed body and local accessories, parts to be replaced and dismantled parts according to the requirements of the original car.

In recent years, we should all see that China's independent brands are constantly improving, and the key core parts are also rapidly improving. The sales of China's top 100 parts enterprises are also increasing, and the R & D investment and institutions are improving. This can fully show that China has indeed made great progress in auto parts. This is a fact that can not be ignored.

Only by strictly controlling the quality can we produce stamping products with more market competitiveness. It is also the goal of every enterprise to create good products with low cost. When we can not control the price of raw materials, we can only choose to operate and test carefully in the production process to reduce the quantity of inferior products.

The common problem of the die in production is that the die always breaks the punch. There are many reasons for breaking the punch. Generally, the thickness of the raw material is relatively thick, and the punch is relatively weak, so it is easy to break the punch. The punch reinforcement problem needs to be paid special attention to when opening the die of stainless steel products.

Precision automobile sheet metal parts are the basic process equipment to realize sheet metal processing. The surface quality of sheet metal stamping parts, precision sheet metal dimensional accuracy, productivity and economic benefits all depend on the reasonable design and manufacturing of the die structure. Therefore, at present, the design and manufacturing of stamping dies are developing in the following three directions.

Sheet metal parts refer to products processed by sheet metal technology. Sheet metal parts have been widely used in our daily life. Sheet metal parts have the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost, good mass production performance and so on. When in use, the common problem is the corrosion of the outer surface.

Nylon is commonly used in the following automotive parts: engine hood, rocker arm cover, cooling and heating devices, and fuel tank. Most nylon resins used in these areas are reinforced with 20-40% glass fiber or other mineral fibers to improve strength. Nylon resin can also be treated with special chemical methods to reduce the disadvantages of hydrolysis and oxidation and enhance the advantages of heat resistance.

From the current development of domestic auto parts enterprises, on the whole, it is still at a low level. There are many production enterprises, but they are relatively scattered. Large and small parts manufacturers are all over the country, but there are few large-scale ones. Due to the decentralization of manufacturers, the competitive advantage of enterprises is not prominent, the data accumulation is small, and the R & D capacity is general, which cannot meet the large-scale demand of foreign investors.

The quality of auto parts is the premise to ensure the quality of the whole vehicle, and the welding process is undoubtedly the basis to ensure the quality of auto parts, so we must pay attention to the welding process of auto parts. The quality of the whole vehicle can only be guaranteed if the production process of each link is fine.
