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.

Las piezas de estampación de automóviles se obtienen bajo la acción de la fuerza de estampación, por lo que habrá cierta deformación, tamaño, forma y otros aspectos de la deformación correspondiente. Para el estampado de piezas, la chapa, el troquel y el equipo son los tres elementos indispensables en el proceso de conformado, que desempeñan un papel vital en la calidad del conformado de los componentes.

Los métodos de prueba para estampar partes de partes automotrices son los siguientes: Prueba táctil: limpie la superficie de la cubierta exterior con una gasa limpia. Los inspectores deben usar guantes táctiles para tocar a lo largo de la parte de estampado verticalmente cerca de la superficie de la parte de estampado. Este método de inspección depende de la experiencia de los inspectores. Si es necesario, el área sospechosa se puede pulir y verificar con piedra de aceite, pero este método es un método de inspección eficaz y rápido.

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.
