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.
