1. Improve the die strength. According to relevant information, the strength of the two-layer composite die is 1.3 times that of the overall die, and the three-layer composite die is 1.8 times the strength of the overall die for a certain size of the die.

For improving the life of the tungsten carbide cold heading dies, many different measures can be adopted, such as improving the lubrication condition, designing a reasonable shape of the cold heading die, reducing the roughness value, and so on. The application of a prestressed combined die is very effective to improve the life of the die.

As cold heading dies are made of tungsten carbide, their properties are factored in tungsten carbide. Tungsten carbide cold heading dies have many properties such as high hardness, wear resistance, toughness, fatigue resistance, excellent polishability, small adhesion to metal, thermal conductivity, and so on.

Tungsten carbide cold heading dies are one type of dies made with tungsten carbide as the main material and cobalt as a binder through compacting and sintering. Tungsten carbide cold heading dies are widely used in molding and fastener-making fields. Usually, tungsten carbide cold heading dies are used as the core insert to be pressed in a steel jacket. Combined with a steel jacket, the cold heading dies are more wear-resistant and work efficient, and the service life is increased a lot.

2. Save die steel. The original overall die is all made of die steel Manufacturing, now the inner ring size is reduced, and the outer ring can be made of alloy steel or medium carbon steel.

4. When the die is damaged, only the inner ring needs to be replaced, and the prestressed ring can still be used without the need to scrap the entire die.

3. Due to the reduced size of the die, the heat treatment operation is easy and the heat treatment quality can be improved.
