With the development of science and technology and the changes of the times, the metal products processing and stamping industry has gradually penetrated into people's lives. Stamping parts can be seen everywhere in life, from daily necessities to aerospace and other large items, metal stamping parts are required. It can be seen that the quality of stamping parts of metal products is also very important. What are the advantages of metal product processing and stamping technology?
1. Technical advantages of metal products processing and stamping
1. Metal stamping parts are manufactured by stamping under the premise of low data consumption. These parts are lightweight and rigid. After the plastic deformation of the sheet metal, the internal arrangement of the metal is improved, so that the stamping part becomes strong.
2. The metal stamping parts have high dimensional accuracy, uniform size and module, and good interchangeability. General device and application requirements can be met without further processing.
3. During the stamping process, since the appearance of the material is not damaged, it has good appearance quality and lubricity, which provides convenient conditions for surface spraying, electroplating, phosphating and other surface treatments.
2. Selection of stamping materials for metal products processing
There are three main stamping processes: stamping, bending and stretching. Different processes have different requirements for plates, and the selection of plates should be considered according to the general shape and processing technology of the product.
3. Selection of oil products for metal products processing and stamping
Stamping oil plays a key role in the stamping process. Good cooling performance and extreme pressure and anti-wear performance make a qualitative leap in the service life of the mold and the improvement of the accuracy of the workpiece. Depending on the workpiece material, the performance focus when selecting stamping oil is also different.
1. Silicon steel sheet is a material that is easier to punch. Generally, in order to clean the workpiece, a low-viscosity punching oil is selected on the premise of preventing punching burrs.
2. When selecting stamping oil, the best viscosity of carbon steel plate should be determined according to the process difficulty, drawing oil method and degreasing situation.
3. Galvanized steel sheet will react with chlorine-based additives, so when selecting stamping oil for galvanized steel sheet, pay attention to the white rust problem that may occur with chlorine-based stamping oil.
4. Stainless steel plate is an easy-hardening material. Stamping of metal products requires the use of high film strength and anti-sintering drawing oils. Generally, stamping oil containing sulfur and chlorine compound additives is used to avoid burrs, cracks and other problems in the workpiece while ensuring extremely high pressure performance.
