First, the material selection of stamping die:
The material types of stamping die include steel, cemented carbide, steel-bonded cemented carbide, zinc-based alloy, low melting point alloy, aluminum bronze, polymer materials, etc. At present, the materials of stamping die are mainly steel, and the common types are carbon tool steel, low alloy tool steel, high carbon and high chromium, medium carbon alloy steel, high-speed steel, basic steel, cemented carbide, steel-bonded cemented carbide, etc.
The materials used to make tungsten steel stamping dies should have high hardness, strength and wear resistance, and also require appropriate toughness and high hardenability. In order to ensure the service life of the mold products, raw materials need to be selected according to the use of the mold, stress conditions, production batches, production efficiency and working status.
Second, the characteristics and advantages of stamping die:
1. The number of parts completed per unit time of the stamping die is several times, or even hundreds to thousands of times, of the general treatment method. Moreover, the stamping process can be combined on a set of molds to further improve production efficiency.
2. The products produced by the stamping die have the characteristics of stable quality, strong mechanical properties, tight structure, good interchangeability, good wear resistance, conducive to maintenance and mass production.
3. High utilization rate of stamping die materials, can use a variety of layout methods, such as, cross, oblique, multi-row, mixing, overcutting, etc., can reduce the material cost of the product.
4. Under normal circumstances, there is no need to heat the material during the stamping process, which not only saves energy, reduces the occupation of heating equipment and site, but also avoids the oxidation, burn and deformation of the product surface caused by heating.
5. Tungsten steel stamping die is widely used, can solve the general processing method can not or difficult to complete the operation, especially suitable for thin, soft, difficult, micro parts processing.
Finally, the processing process of the stamping die is very simple, the technical requirements of the operator are not high, the labor intensity is low, and after receiving short-term work training, the worker can start to operate. And in the operation process, the basic action of the worker is the same, not affected by the complexity of the product.
