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.

Body correction refers to the process of repairing the parts damaged by accident or fatigue to the technical standard "state" when the vehicle leaves the factory through certain external force. For the word "state", it has two meanings. "Shape" refers to a more intuitive appearance and shape, while "state" is a more abstract and deeper concept, such as whether the internal molecular structure of metal can be rearranged according to the original position, whether the internal stress is completely released, etc., which will directly affect the function and life of the vehicle after repair. Structural parts refer to the components that play the main supporting and bearing role on the body, and are the installation foundation of body parts, which are common in the longitudinal beam, cross beam, door post, lower side beam and other parts. This kind of component usually has very high strength, and the structure is mostly closed box section, so when repairing, we should take certain means and measures, and use reasonable technology to repair.

The production and selection of auto parts can't be sloppy. If the product quality can't be guaranteed, not only the vehicle will be damaged, but also there will be potential safety hazards. The following are familiar auto parts, which are also easy to appear fake products. We must master this.

In many kinds of auto parts, spark plug is usually easy to be ignored, but it is very important in the whole car. What should be paid attention to when using such parts?

When processing all kinds of customized cabinet case, air conditioner sheet metal and other sheet metal parts, automobile sheet metal parts need surface treatment, such as spraying, electroplating, anode, electrophoresis, etc. Because some materials of sheet metal do not have the function of anti rust and anti-corrosion, it is necessary to make surface treatment to achieve the effect of anti rust and anti-corrosion; in addition, the surface treatment can also achieve the effect of beautifying the product appearance.

Precision automotive stamping dies 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 by a mechanical hand, 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.

With the continuous development of sheet metal processing, the demand for laser processing equipment is more and more obvious, especially in high-power laser equipment.

Automobile stamping parts, as the name implies, are the metal stamping parts of automobile parts. In automobile stamping parts, one part is directly formed into automobile parts after stamping, and the other part needs to be welded, machined or painted after stamping. There are many kinds of automobile stamping parts, such as spring tray, spring seat, spring bracket, end cover, cover, compression valve cover, compression valve sleeve, oil seal seat, bottom cover, dust cover, impeller, oil cylinder, support and so on.

CNC machining center is widely used in the current machining market, and the future development trend is very good. It can be said that most parts are related to CNC machining. Especially in the auto parts industry, the vast majority of products are processed by CNC. For example, bumper, instrument panel, door plate rotating shaft, transmission shaft, gear, gearbox, wheel hub, brake drum, etc., first process small parts through CNC, and then bond them.

If it is found after investigation that the surface of the round corner of the die is rough, which causes the scratch on the surface of the stamping part, the round corner radius of the die should be polished. In addition, if there is dirt on the working surface or material surface of the stamping die during the stamping process, which causes the workpiece to be injured, it is necessary to keep the surface of the convex and concave die clean, and clean it before starting the work.
