Is stamping die used only for general and special requirements?

Because of the simple structure of the stamping die and the large positioning error, the precision of the parts is low, and there is no high precision of the continuous die and the compound die. Low life, easy to wear. It is only suitable for small batch production with low precision and simple shape and trial production of new products. The part lap boundary value is bigger and the material utilization ratio is lower than that of the compound die. For parts with complex shapes, the die structure is complex and the manufacturing is difficult.

The parts with thin wall, light weight, good rigidity, high surface quality and complex shape can be obtained which can not be manufactured by other processing methods. This is widely used in various fields of national economy. For example, aerospace, machinery, electronic information, transportation, weapons, household appliances and light industry industries have stamping processing.

The punch parts of Dalian stamping die are usually made of SKD11, and stainless steel is made of SKH-9 or DC53 or ASP-23; DC53 is a little worse than SKH-9, and ASP23 is better than SKH-9; tungsten steel is also used as a general special requirement, which is expensive; high-quality carbon structural steel, alloy structural steel, carbon tool steel, stainless steel, electrical silicon steel and so on; non-ferrous metals mainly include pure copper, brass, bronze, electric silicon steel, etc. Aluminum, etc. Non-metallic materials include cardboard, laminate, rubber board, plastic board, fiberboard and mica, etc.

SKH-9 or DC53 or ASP-23 will be selected for stamping stainless steel materials; DC53 is a little worse than SKH-9, ASP23 is better than SKH-9; and tungsten steel, which is a general special requirement, is used. Commonly used die working parts materials are carbon tool steel, low alloy tool steel, high carbon high chromium or medium chromium tool steel, medium carbon alloy steel, high speed steel, matrix steel and cemented carbide, carbon tool steel base. A suitable amount of alloying elements was added.

Compared with carbon tool steel, it reduces the tendency of quenching deformation and cracking, improves the hardenability and wear resistance of steel. It has good hardenability, hardenability and wear resistance. The heat treatment deformation is very small. It is a high wear-resistant micro-deformation die steel, and its bearing capacity is second only to that of high-speed steel.
