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.

Cuando las piezas de chapa de automóviles se procesan en varios tipos de chasis de gabinetes personalizados, piezas de chapa de aire acondicionado, deben tratarse en la superficie, como pulverización, galvanoplastia, ánodo, electroforesis, etc. Debido a que algunos materiales de chapa no tienen la función de antioxidante y anticorrosión, se necesita un tratamiento de superficie para lograr el efecto de antioxidante y anticorrosión. Además, el tratamiento superficial también puede lograr el efecto de embellecer la apariencia de los productos.

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, hay cientos de partes en la carrocería de un automóvil, y las piezas de estampado automático representan una gran parte de la carrocería. El estampado de hardware de piezas de automoción es la tecnología de producción de piezas de productos con cierta forma, tamaño y rendimiento mediante la potencia de un equipo de estampado convencional o especial, de modo que la chapa metálica está directamente sujeta a la fuerza de deformación y a la deformación en la matriz. Para obtener buenos productos de estampado, es necesario hacer un buen trabajo de diseño previo al estampado.

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.

Las piezas de estampado de hardware ahora son muy comunes en China, y hay numerosos fabricantes de grandes y pequeños. Piezas de estampado de hardware en el proceso de estampado, si no presta atención a la superficie es muy vulnerable al daño, ¿cómo resolver este 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.

El probador de dureza Rockwell se utiliza para probar la dureza de piezas de estampado de metal. Se pueden usar pequeñas piezas de estampado con formas complejas para probar que el avión es muy pequeño y no se puede probar en el probador de dureza Rockwell de escritorio ordinario.

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.

El cuerpo está montado en el marco del chasis y es transportado o cargado por el conductor y los pasajeros. El cuerpo del autobús es generalmente una estructura integral, y el cuerpo del camión generalmente está compuesto de cabina y contenedor.

Muchos propietarios de automóviles creen que se necesita el mismo color de pintura del automóvil después de rociar las piezas de chapa, por lo que el proceso de rociado de las piezas de chapa se descuidará en la selección de las piezas de chapa, pensando que no es importante, pero esta idea Es incorrecto. Para evitar la oxidación y la oxidación, las piezas de chapa metálica deben rociarse antes de salir de fábrica. De hecho, los enlaces de pulverización después de reemplazar las piezas de chapa no solo pueden tonificar sus colores, sino que también protegen y evitan la oxidación.

​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.
