Customized High Corrosion Resistance Polished YG6,YG8,YG10,YG15 Tungsten Carbide Punching Dies
Application
At present, the majority of tungsten carbide punching dies using WC-Co alloy . This tungsten carbide has high hardness, high melting point, stable, suitable for making the mold material. Because lubricity of WC is better than Co, and with high solubility at high temperatures; at normal temperature, WC solubility ratio of Co is small, so it can maintain a certain toughness. WC-Co cemented carbide is currently the most widely used, the largest output of carbide.Thanks to the combination of WC and Co properties,they have excellent performance
Tungsten carbide punching dies mainly processing of bolts, nuts,
steel wall nails, wood screws and rivets and other common parts in
industrial production.Conventional bolt cold forming process can be
divided into expected, upsetting head, accumulate, forming, gaining
five steps. Stamping advantage are the high material utilization,
metal consumption, high production efficiency, high degree of
automation. In the course of the punching dies working ,it had to
bear a huge impact, unit pressure up 200MPa, and therefore requires
a mold material with high hardness, high wear resistance, high
impact strength and fatigue sufficient toughness.
Tungsten carbide cold heading dies material has the following characteristics
1. High wear resistance. Tungsten carbide cold heading dies
material high wear resistance, tensile modulus can be guaranteed
long-term work in any degree of deformation, ensuring standard size
unchanged.
2. Excellent in polishing. Carbide has a good polishing, can be
processed into the die hole mirror light, ensuring high quality
standard surface.
3. Adhesion to metal is small. In the tungsten carbide cold heading
process, ferrous metal material adhesion small carbide tooling
materials, ensuring a high tungsten carbide cold heading die life.
4. The friction coefficient and energy consumption is small.
5. High thermal conductivity. Since the thermal conductivity of the
tungsten carbide die is high, heat generated during the cold
forging can quickly conducted away to improve the durability of the
mold.
6. Good corrosion resistance.
