In the process of Custom stainless steel stamping and stretching, mold design plays a vital role. Here are some key mold design points.
First, material selection is the basis. Since stainless steel has high hardness and strength, the mold material needs to have sufficient hardness, wear resistance and toughness. Commonly used mold materials include alloy tool steel, high-speed steel, etc. These materials can withstand the high pressure and friction during stainless steel stamping and stretching, ensuring the service life of the mold.
Secondly, the structural design of the mold should be reasonable. For stamping dies, suitable punches and concave dies should be designed according to the shape and size of the product. The gap between the punch and the concave die should be precisely controlled. Too small a gap will cause the mold to wear more severely, and too large a gap will affect the dimensional accuracy of the product. For stretching dies, appropriate stretch coefficients and fillet radius should be designed. Too small a stretch coefficient can easily cause product rupture, and too small a fillet radius will increase the stretching resistance and affect product quality.
Furthermore, the surface treatment of the mold is also very important. The wear resistance, corrosion resistance and demolding performance of the mold can be improved through surface treatment. Common surface treatment methods include nitriding, hard chrome plating, etc. These treatment methods can form a hard protective film on the surface of the mold, reduce the friction between the mold and stainless steel, and increase the service life of the mold.
In addition, the design of the cooling system of the mold cannot be ignored. During the stamping and stretching process, the mold will generate a lot of heat. If the heat cannot be dissipated in time, it will affect the performance of the mold and the quality of the product. Therefore, it is necessary to design a reasonable cooling channel to ensure that the mold can maintain a suitable temperature during operation.
Finally, the precision requirements of the mold are very high. During the design process, the processing accuracy and assembly accuracy must be fully considered. Advanced processing equipment and processes are used to ensure the dimensional accuracy and surface quality of the mold. At the same time, during the assembly process, the assembly must be carried out in strict accordance with the design requirements to ensure the matching accuracy between the various parts of the mold.
In short, the key points of mold design in the process of Custom stainless steel stamping and stretching include material selection, structural design, surface treatment, cooling system design and precision requirements. Only by fully considering these key points can high-quality molds be designed to ensure the quality and production efficiency of stainless steel stamping and stretching products.
