When trimming the die of automobile stamping parts, there is often a headache, that is, the phenomenon of dropping iron chips. Especially around the lower die scrap knife, this situation will be more obvious. This will have a great negative impact on the quality and appearance of stamping products, so we need to deal with it in time.

A large number of cold stamping processes have been used in the production of automobile parts and stamping parts, which are suitable for the needs of automobile stamping parts industry with many varieties and large batch production. In medium and heavy-duty vehicles, most of the covering parts, such as body outer panel, and some load-bearing and supporting parts, such as frame, carriage and other auto parts are automobile stamping parts.

The inspection methods for stamping parts of automobile parts are as follows:

In fact, there are a lot of knowledge to know about automotive stamping parts, many problems are usually out of your reach. When you apply different stamping parts in different industries, you need to know different knowledge points. Next, stamping is a simple way for you to understand.

Precision stamping die can be classified into three categories as follows: Engineering die, also known as "single process Die", refers to the die that can only complete one stamping process in one stroke of stamping. After the completion of this project, the products need to be taken out of the mold manually or with a manipulator, and then put into the mold of the next station to continue production, until the next process of the mold is completed, the whole product is completed. The mold maintenance is simple, but the production is time-consuming and laborious, which requires more labor and time cost, and the product scrap rate is high.

Stamping is widely used in various fields of national economy. For example, there are stamping processes in aerospace, aviation, military industry, machinery, agricultural machinery, electronics, information, railway, post and telecommunications, transportation, chemical industry, medical equipment, daily electrical appliances and light industry. Rongzhi automobile stamping parts said that not only the whole industry uses it, but also everyone has direct contact with stamping products.

Why stainless steel is not used for automobile sheet metal parts? At present, the sheet metal materials used in automobile are basically cold-rolled galvanized steel sheet, which has been stamping for many times, which requires that the materials must have good ductility and shape fixing ability, while the ductility and shape fixing ability of stainless steel is relatively poor, and the stamping plasticity is not good, so it is difficult to meet the process requirements of multiple stamping and complex forming.

The difference between automobile stamping parts and castings is that stamping parts are thin, uniform, light and strong, which can make workpieces with stiffeners, ribs, undulation or flanging that are difficult to be made by other methods, so as to improve their rigidity. Due to the use of precision dies, the accuracy of workpieces can reach micron level, and the difference between heavy stamping parts and castings: workpieces with stiffeners, ribs, undulations or flanging that are difficult to manufacture by other methods can be made by stamping with the characteristics of thin, uniform, light and strong, so as to improve their rigidity. Due to the use of precision die, the precision of workpiece can reach micron level, and the repetition precision is high, the specification is consistent, and the hole and socket, boss, etc. can be punched.

Rockwell hardness tester is used for hardness test of hardware stamping parts. Small stamping parts with complex shape can be used to test the small plane, which can not be tested on ordinary Rockwell hardness tester.

The application of sheet metal technology in all walks of life has brought us many conveniences. In addition to the daily use of various sheet metal parts, sheet metal chassis cabinets and other daily sheet metal products, sheet metal technology has also been applied in many aspects in our life. The repair of automobile sheet metal parts is an important part.

In the automobile market, we will find that in addition to the relevant parts and components of the automobile, the automobile stamping products also exist. The difference is that they are the parts and components materials that need to be processed, welded, or completed by other processes. In particular, what impact do these stamping parts have on the automobile?

Sheet metal parts are thin and easy to form, which can be formed into parts of various shapes. With the application of welding, assembly, riveting and other processes, it is possible to realize multi structure products. At the same time, these characteristics also make sheet metal parts in the process of processing will more or less occur different degrees of deformation, such as bending deformation, torsion deformation, concave convex deformation and so on. These deformations make the size or shape of the whole component change, resulting in quality problems. However, the production process of sheet metal parts has its own rules. For the same type of products, according to the existing equipment, manpower, etc., the sequence of processing can be flexibly adjusted to give a reasonable processing process. So choosing the right process route is an effective measure to prevent and solve this kind of problem.

Stamping part is a kind of forming processing method which uses press and die to exert external force on sheet, strip, pipe and profile to produce plastic deformation or separation, so as to obtain the required shape and size of workpiece (stamping part). Rongzhi automobile stamping parts show 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.

The processing technology of automobile stamping parts is more and more widely used. Many accessories, including tools, are made by machine stamping. For example, the lampshade of automobile, we all know that the shape of lampshade is elliptical, which is not easy to produce. With stamping technology, it can be well realized.

A large number of cold stamping processes have been used in the production of automotive stamping parts, which are suitable for the needs of many varieties and large-scale production of automotive stamping parts industry. In medium and heavy-duty vehicles, most of the covering parts, such as body outer panel, and some load-bearing and supporting parts, such as frame, carriage and other auto parts are automobile stamping parts.

In our life, our daily necessities are often rusty due to some reasons, but there are the same problems in my sheet metal processing console. Because of the storage problem, when we put the sheet metal processing console in the basement, its humidity will be relatively high, and we will timely carry out moisture-proof and hygroscopic work for him after being affected by the humidity.

The inspection method of automobile stamping parts is an important method to ensure the quality of finished products and high qualified rate. For the operators of stamping parts production enterprises, they generally need to master how to conduct inspection. Next, Rongzhi automobile stamping parts mainly collated six inspection methods, which can be divided into three categories through careful analysis: sensory inspection, grinding inspection and tool inspection.

For the concave and convex of the stamping metal surface, most of them are caused by the impurities attached to the raw materials or stamping dies; or in the stamping process, the automobile parts and dies are collided; the height of the raw material conveyor belt is not reasonably adjusted; the deformation of the working tools and so on. All of the above mentioned problems may cause deformation and concave convex of stamping parts.

If it doesn't reach the accuracy, one is that the automotive stamping parts can't be used, even if it can be used, but it can't reach its own performance, and there is a great danger. Next, the stamping parts should reach a good hardness, of course, this has a lot to do with its production materials.
