Stamping and drawing oil belongs to metal processing oil, which is suitable for ultra-high strength tensile forming, pipe drawing stamping forming, punching, shearing, broaching, etc. Stamping and drawing oil is divided into water-soluble stamping and drawing oil, metal stamping and drawing oil and aluminum stamping and drawing oil.

With the continuous reform and development of the industrialized industry, users have more and more proportion in stamping parts processing, and the processing function in the mechanical aspect pays more attention to the standardization of cost and application. The quality of stamping technology directly affects the subsequent production and input components. Compared with the traditional processing, the new form of stamping processing has higher production efficiency and has more advantages in the use of operation functions, especially the parts with uniform quality and high strength have stronger ribs.

Precision stamping dies can be classified into three categories as follows: Engineering die: also known as "single process Die", which refers to the die that can only complete one stamping process in one stroke of stamping. After the completion of this project, the product needs to be taken out of the mold manually or by manipulator, and then put into the mold at the next station to continue production. The whole product is not completed until the next process of the mold is completed. Mold maintenance is simple, but production is time-consuming and laborious, requires more labor and time costs, and the product scrap rate is high.

Stamping part is a forming and processing method of applying external force to plate, strip, pipe and profile by press and die to produce plastic deformation or separation, so as to obtain the workpiece (stamping part) with required shape and size. Automotive stamping parts mean that stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. The billets for stamping are mainly hot-rolled and cold-rolled steel plates and strips.

Stamping parts processing technology is more and more widely used. Many accessories, including tools, are stamped by machines. For example, the lampshade of an automobile, we all know that the shape of the lampshade is oval. This shape of accessories is not easy to produce. It can be well realized by stamping technology.

Although the steady development of China's auto parts industry in recent years has laid a foundation for the development of the auto parts industry, and from the development prospect of the auto industry, it is expected to maintain a stable growth trend in the next few years, which will provide a broad space for China's auto parts industry, the future development of the industry is still faced with low industry concentration The core technology of key parts of domestic enterprises is immature and the industry's research and development ability is weak, which is mainly reflected in the following three weak links:

The application of sheet metal technology in all walks of life has brought us a lot of convenience. In addition to the use of daily sheet metal products such as various sheet metal parts, sheet metal chassis and cabinets, sheet metal technology has also been actually applied to many aspects in life. Automobile sheet metal repair is an important part.

Sheet metal processing is sometimes also used for metal drawing. The word comes from English platemetal. Generally, some metal sheets are pressed by hand or die to produce plastic deformation to form the desired shape and size, and more complex parts can be formed by welding or a small amount of mechanical processing, such as chimneys and tin furnaces commonly used in families, And the car shell is made of sheet metal.

1、 Check the drying quality of the paint film Press the paint surface with your fingers to see if there are obvious hand lines, which prove that the paint film is not dry

For the trimming sequence die of stamping parts, it is easy to have the upper die clamp with material in the commissioning stage. The main reasons are as follows:

In the cost of automobile stamping parts, the material cost is about more than 60%. Therefore, the economic utilization of materials is of great significance. Layout refers to the layout of parts on strip or sheet.

Because the stamping process has the characteristics of stable quality, good interchangeability, good rigidity and high efficiency, it is widely used in various fields. Stamping processing is available in aerospace, machinery, electronic information, transportation, weapons, daily electrical appliances and light industry. It is not only widely used in the industry, but also has an inevitable connection with stamping products in everyone's daily life. Stamping can produce micro precision parts in clocks and instruments, as well as large covering parts of automobiles and aircraft.

The galvanized surface of precision stamping parts is a little cyan white, and the luster is not very bright. Play the role of decorative effect.

The galvanized surface of precision stamping parts is a little cyan white, and the luster is not very bright. Play the role of decorative effect.

The residual liquid medicine and additives in the interior of precision stamping parts spit out, and the tin layer attached to the electroplating is very easy to be corroded by these substances. Cause surface oxidation and yellow coating.

With the continuous improvement of automotive aftermarket services, modern automotive sheet metal maintenance has been a technology closely related to the rights and interests of consumers and even life. In short, no matter whether the automobile maintenance sheet metal is regarded as an important part of the automobile maintenance technology, or it has been separated from the automobile maintenance technology and become a relatively independent professional type of work, the automobile maintenance sheet metal technology has occupied an important position in the automobile maintenance industry, and its maintenance technology can be stronger than any aspect of the automobile maintenance technology Bijing, its working environment is already a place full of high-tech atmosphere.

All auto parts shall be stored in warehouse or covered dry site, free from harmful gas erosion and influence, well ventilated, and shall not be stored together with chemicals and acid-base materials.

See if the trademark logo is complete. The outer packaging of authentic products is of good quality, the handwriting on the packaging box is clear and the overprint color is bright. The packing box and bag shall be marked with product name, specification, model, quantity, registered trademark, factory name, address, telephone number, etc. some manufacturers also make their own marks on the accessories. Some important parts, such as generator, distributor and fuel injection pump, are also equipped with operation instructions, certificate and inspector seal to guide users to use and maintain correctly. When purchasing, we should recognize it carefully to prevent buying fake and shoddy products.
