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.

The sheet metal parts produced by regular manufacturers will be mechanically cut and welded. The welding points or cutting edges are flat and smooth, and rough edges of rough cutting hands will not be left.

Car stamping parts play a very important role in the car industry, so when producing such stamping parts, the raw materials are also widely used. Generally, when producing such stamping parts, most of them use the cold stamping process to produce or process.

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 common problem of dies in production is that the dies always break the punch. There are many reasons for breaking the punch. Generally, the thickness of raw materials is relatively thick, and the punch is relatively weak, which will easily break the punch.

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.

check whether the trademark is complete. The outer packaging of authentic products is of good quality. The writing on the packaging box is clear and the overprint color is bright.

The cutting processing of automobile sheet metal parts is not only to change the shape, but also to deal with the thickness and other aspects. In this way, the effect of using in different cases is also different.

Compared with the high-tech and high brand barriers of traditional fuel vehicles in the field of auto parts, new energy vehicles are regarded as a new starting line, and even an opportunity for independent brands to overtake in the corner. However, due to multiple factors such as unclear market orientation, new energy vehicles have not yet fully exploded, and the volume of fuel vehicles is still large, honeycomb Yichuang's products still adopt the development path for the development of traditional fuel vehicles, hybrid vehicles, pure electric vehicles and other types of vehicles.

With the development of the times, many foreign automobile mold manufacturing technologies are gradually replaced and covered by computer technology. The high-precision processing mode makes the mold manufacturing more standardized and accurate. This high-tech is worth learning from by our country. In the production of automobile stamping die, CAD, cam, CAE, vacuum treatment technology, laser heat treatment and welding technology have their own intellectual property software, and have been well applied. After practical training, many domestic automobile stamping die enterprises have successfully applied CAE technology to realize the ability of Synchronous Engineering Analysis of automobile digital simulation and stamping process.

In recent years, we should all see that China's independent brands are constantly improving, 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, which can fully show that China has indeed made great progress in auto parts, which can not be ignored.

Titanium is a metal material commonly used in the processing of precision automotive stamping parts. Titanium alloy is an alloy material composed of titanium as the basic element and mixed with other metal elements. It has the advantages of low density, high strength, good corrosion resistance, high heat resistance, easy welding and good process performance. It can be processed into various titanium alloy products, which are widely used in the following industries.

With the change of transportation, the rapid development of automobile industry is followed, especially the development of automobile sheet metal trimming technology. In the process of this process operation, we should pay more attention to the cold stamping of thin plate, try to improve the quality of automobile surface plate, improve the manufacturing process of automobile outer plate, use high-tech means to innovate operation, improve the service time of materials, seek new materials, reduce the human and material resources of automobile parts manufacturing enterprises, solve the debris problem in the process of process operation, and improve the quality of parts.

Selection principle of stamping die for automobile stamping parts

With the intensification of the market competition of automobile stamping parts, domestic parts enterprises gradually increase the R & D investment in new products and new technologies. According to the data on R & D investment in the 2012 annual report of the top 30 listed companies in the operating revenue of auto parts sorted out by China auto news, the R & D investment of most enterprises accounts for an average of 2.70% of the operating revenue, and the average investment amount is 244 million yuan.
