In fact, the basic coating process of automobile sheet metal parts is widely used in the whole process of body sheet metal repair. According to the author's experience in automobile sheet metal repair for many years, the specific application of basic coating technology in the repair and replacement of body sheet metal parts can be classified into the following categories:

Whether the die used for metal stamping parts adopts the elastic unloading plate or the fixed unloading plate depends on the unloading force, and the material thickness is the main consideration. With the increase of the elastic force of the elastic element for the mold (such as the rectangular spring), the unloading force of the elastic unloading plate is greatly enhanced. Metal stamping parts are the forming and processing methods that apply external force to plates, strips, pipes and profiles by means of presses and molds to produce plastic deformation or separation, so as to obtain workpieces (stamping parts) of required shape and size.

The quality inspection of automotive stamping parts shall meet the following requirements: smooth surface, clear ridge lines, sufficient rigidity and dimensional stability, and no wrinkle, scratch, roughening and other defects.

The damage of the front part of the automobile sheet metal parts is caused by the head of the vehicle hitting another vehicle or other objects. The impact force depends on the vehicle weight, vehicle speed, impact object and impact area. If the collision is small, the bumper will move backward, causing bending and deformation of the front side member, bumper seat, front fender, radiator support and engine hood lock pillar.

The repair of impact damage of automobile stamping body is mainly accident wound repair, and the commonly used methods are shrinkage shaping, wrinkle unfolding, bracing and pulling and pad pry reduction.

Most of the sheet metal parts of the automobile body are produced in batch, and the forming process is completed on the mechanical equipment. Most manual operations are auxiliary processing, but single piece processing or repair are mainly manual operations. The common manual processes of sheet metal manufacturing include bending, edge closing, edge setting, edge pulling, arching and curling, seam biting and correction, etc. at the same time, welding, willow joint and other methods are used to realize the permanent connection between various sheet metal parts.

To distinguish the quality of sheet metal parts, generally speaking, we can start from the aspects of packaging, weight, welding process, painting process and the degree of coincidence during loading. It is very difficult for ordinary car owners to distinguish whether the sheet metal parts are of high quality after the delivery of the car. It might as well be distinguished from the product packaging in advance: generally, the products produced by small factories will not be printed with contact information and address, while the regular manufacturers will also have steel seals, qualifications and testing labels on the products in addition to the contact information and address. Even if consumers have problems in the use process in the future, they can also have a way to protect their rights.

Stamping parts are sheet metal parts, which can be processed by stamping, bending, stretching and other processes through metal stamping dies. The corresponding parts are casting parts, forging parts, machined parts, etc. with the rapid development of stamping technology, the requirements of manufacturing and machinery industry are continuously raised. Precision metal stamping dies are widely used in new energy, automation equipment, medical devices The development momentum of molds in aerospace, energy conservation and emission reduction and other product fields is strong.

A large number of cold stamping processes are used in the production of automotive stamping parts, which is suitable for the needs of multi variety and mass production of automotive stamping parts industry.

Automobile stampings, as the name suggests, are metal stampings that constitute automobile parts. In the automobile stamping parts, one part of them becomes automobile parts directly after stamping, and the other part can become automobile parts only after welding, machining, or painting.

The outstanding advantage of modular stamping is that it can organically combine the flexibility of stamping processing system with efficient production. Flexibility has a wide meaning, such as the various requirements for the geometric shape of stamping parts, which can be obtained by free programming, reflecting the flexibility of machining shape. For example, it is not only suitable for the production of large-scale single variety stamping parts, but also gives play to the advantage of small-scale multi variety processing, and also shows flexibility.

Stamping process is one of the processing methods to complete metal plastic forming. Usually, external force is applied to plate, strip, pipe and profile by press and die to produce plastic deformation or separation, so as to obtain the workpiece with the required shape and size.

Stamping 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 the required shape and size. Stamping and forging belong to plastic processing (or pressure processing), which are collectively called forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips.

When it comes to metal stamping, I believe that many mechanical, automotive, electronic, hardware and other industries have been applied. Metal stamping can make products better formed, but we need to clean them after stamping every time. Many businesses want to know how to clean metal automotive stamping parts after stamping.

Sheet metal processing is sometimes used as metal pulling. This word comes from English sheet metal. Generally, some metal sheets are plastically deformed by manual or die stamping 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, tin furnaces and automobile shells commonly used in families.

The painting processing of automobile body parts is an operation with professional skills. In the operation, we need to pay attention to whether the paint is uniform, whether the paint surface is flat, and whether the paint color is consistent with the vehicle body color. Therefore, when our car needs painting after bumping, we should first understand some matters needing attention in automobile body painting, so that it will not be damaged during service. What matters need to be paid attention to?

In the automobile sheet metal processing industry, the use of lubricating oil is very important, because the proper application of lubricating oil to the machine can make it use longer. The application of lubricating oil during production can help better production, but it should be noted that the application method and lubrication method of lubricating oil, because improper use will not work and may have the opposite effect, Let's take automobile lubrication as an example to introduce you to the three misunderstandings in the use of lubricating oil.

Sheet metal processing is the key technology that sheet metal technicians need to master, and it is also an important process for the formation of sheet metal products. Automobile sheet metal parts include not only the traditional cutting and blanking, blanking, bending forming and other methods and process parameters, but also various cold stamping die structures and process parameters, various equipment working principles and operation methods, as well as new stamping technology and new process.

Sheet metal craftsmen are also called sheet metal processing. Specifically, for example, sheet metal is used to make iron drums, oil tanks, oil pots, ventilation pipes, elbow heads, Tianyuan places, funnel shapes, etc. the main processes of automobile sheet metal parts are cutting, bending, edge buckle, bending forming and welding, which requires certain geometric knowledge. Sheet metal parts are sheet metal parts, which can be processed by stamping, bending, stretching and other means. A general definition is the parts with constant thickness in the processing process.

After the automobile sheet metal parts are repaired or repaired, the next process is very important, that is, cleaning. Do a good job in cleaning, and the automobile body will take on a new look. So how to clean it? Xiaobian, let me share my method.
