As the name implies, automotive stamping parts are metal stamping parts that constitute automotive parts. In automotive stamping parts, one part becomes automotive parts directly after stamping, and the other part can only become automotive parts after stamping through welding, mechanical processing, or painting process.

Auto sheet metal processing is the technology to process sheet metal. It includes not only the traditional cutting, blanking, bending and forming methods and process parameters, but also the structure and process parameters of various cold stamping dies, working principles and operation methods of various equipment, as well as some new stamping technology and process. More and more sheet metal processing enterprises realize that proper surface treatment can play a very good role in decoration and protection of the product surface, improve the product's "face value", and then improve market competitiveness.

Quando peças de chapa metálica de automóvel são processadas em vários tipos de chassi de gabinete personalizado, peças de chapa metálica de ar condicionado, elas precisam ser tratadas de superfície, como pulverização, galvanoplastia, ânodo, eletroforese e assim por diante. Como alguns materiais de chapa metálica não têm a função de antiferrugem e anticorrosão, é necessário tratamento de superfície para obter o efeito de antiferrugem e anticorrosão. Além disso, o tratamento de superfície também pode obter o efeito de embelezar a aparência dos produtos.

Spray painting of automobile sheet metal parts is an operation with professional skills. In operation, attention should be paid to the uniformity of the spray paint, the smoothness of the paint surface, and whether the color of the spray paint is consistent with the color of the car body. Therefore, when our car bumps into the need for spray painting, we should first understand that spray painting of automobile sheet metal should pay attention to one. Some things, in order to do services will not be pitted, then what matters need attention?

Como todos sabemos, existem centenas de peças no corpo de um carro, e as peças de estampagem automática representam uma grande parte do corpo. A estampagem de hardware de peças automotivas é a tecnologia de produção de peças de produtos com certa forma, tamanho e desempenho por meio do poder de equipamentos de estampagem convencionais ou especiais, para que a chapa seja diretamente sujeita a força de deformação e deformação na matriz. Para obter bons produtos de estampagem, é necessário fazer um bom trabalho no projeto de pré-estampagem.

In our life, we often rust our daily necessities for 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. After being damp, we should timely carry out moisture-proof and moisture-absorbing work on it.

Residual medicines and additives are vomited from the inside of precision stamping parts, and the tin layer attached to the plating is easily corroded by these substances. It causes surface oxidation and yellowing of the coating. Inadequate treatment and no drying of the workpiece can also lead to yellowing of the coating. Adhesion of tetravalent tin, excessive additives, zinc impurity pollution in bath (less likely), insufficient thickness of coating, iron impurity pollution (phenomenon is not easy to find in the process of plating) and storage environment. These are the reasons that lead to yellowing of precision metal stamping parts.

As peças de estampagem de hardware são agora muito comuns na China e existem numerosos fabricantes de grandes e pequenos. Peças de estampagem de hardware no processo de estampagem, se você não prestar atenção à superfície é muito vulnerável a danos, então como resolver esse problema?

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, it is necessary to take the product out of the mould manually or with a manipulator, and then put it into the mould of the next station to continue production, until the latter process of the mould is completed, the whole product is not completed. Mould maintenance is simple, but the production is time-consuming and laborious, which requires more labor and time costs, and the rejection rate of products is high.

Stamping process can be roughly divided into separation process and forming process (also divided into bending, deep drawing, forming) two categories. Separation process is to separate stamping parts and blanks along a certain contour line in the stamping process, and the quality of the separated section of stamping parts must meet certain requirements. Forming process is to make the stamping blanks plastic deformation without destroying and transform into the required finished product shape, and also to meet the requirements of the size of the common. Poor and other requirements.

In the production process of automobile sheet metal parts, there are certain requirements for stamping technology and stamping die. In high-speed stamping equipment and multi-function stamping die, only "high-speed" and "multi-function" can not meet the production requirements, only to achieve continuous conveying of sheet metal to stamping machine and stamping die, and stamped sheet metal workpiece can be removed from the stamping die and conveyed to the next stamping worker in a very short time.

Metal plastic forming is a process in which metal materials are processed by means of their plastic properties to give them the desired shape. After forming, the structure and properties of metal materials are improved and improved.

The anti-collision beam of automotive parts is by no means the fundamental factor to ensure the safety of the personnel in the car, but it is meaningful to the safety. Its function is reflected in the low-speed collision, while in the high-speed accident, the anti-collision beam of automotive parts is powerless.

It is obvious that the necking of automobile stamping parts is difficult to detect. First of all, the mechanism of material deformation is understood. The process of material stretching and plastic deformation is mainly composed of three stages: uniform elongation stage, local elongation stage and cracking stage.

O testador de dureza Rockwell é usado para testes de dureza de peças de estampagem de metal. Peças pequenas de estampagem com formas complexas podem ser usadas para testar se o avião é muito pequeno e não pode ser testado em um testador de dureza Rockwell comum para desktop.

Generally speaking, the working rhythm of stamping machine determines the production rhythm of stamping production line. The working time of the feeding and unloading mechanism and the workpiece conveying mechanism of the stamping production line should coincide with the stamping time of the stamping machine tool. In order to reduce or eliminate the assistant time of punching machine and die as much as possible, the loading and unloading device of sheet metal and the transport mechanism of workpiece must be able to complete the tasks of loading and unloading and conveying of workpiece as soon as possible so as to reduce the downtime of punching production line.

O corpo é montado na estrutura do chassi e é transportado ou carregado pelo motorista e passageiros. A carroceria do barramento geralmente é uma estrutura integral e a carroceria do caminhão geralmente é composta por cabine e contêiner.

Muitos proprietários de carros acreditam que a mesma cor da pintura do carro é necessária após a pulverização das peças de chapa, portanto o processo de pulverização das peças de chapa será negligenciado na seleção de peças de chapa, pensando que não é importante, mas essa ideia está incorreto. Para evitar oxidação e ferrugem, as peças de chapa metálica precisam ser pulverizadas antes de saírem da fábrica. De fato, os elos de pulverização após a substituição das peças de chapa metálica podem não apenas tonificar suas cores, mas também proteger e impedir a oxidação.

​Body straightening refers to the process of repairing parts damaged by accident or fatigue to the "state" of the technical standard when the vehicle leaves the factory through a certain external force.
