High Strength and ToughnessTungsten Carbide Serrated Die

  Cold heading die is one of the steel dies. It is made of alloy materials with high strength and hardness, corrosion resistance, wear resistance and high temperature resistance, which is far longer than the service life of ordinary steel dies. It is a popular die in modern machinery industry. Its characteristics are as follows:

  1) the guiding mechanism of the die adopts the four guide pillar ball mold base, and the stability, reliability and accuracy of the guiding mechanism are very high.

  2) use T7 as the raw material of the hardened base plate to avoid the crushing of the cemented carbide die during stamping.

  3) most of the formwork bases are made of 45 steel, hrc38-420, which is thicker than the general steel formwork and increases the rigidity.

  4) at the die handle, in order to prevent the impact of the precision of the press on the stamping process of the carbide die, the floating die handle structure should be adopted as far as possible.

  5) the clearance of the concave convex die is larger than that of the steel die.

  6) in order to prevent the impact on the die during stamping, the fixed discharge plate structure is adopted, and the height h of the step is one thick material different from the thickness h of the guide plate.

The selection of the material for the cold heading die is very important. The service life time depends on the quality of the tungsten carbide inside. We use authentic CB-CERATIZIT tungsten carbide to ensure effective life.
