The Processing Method of Forging Billet for Sprocket

First of all, the understanding of the material:

      Different materials have different properties of parts, the general carbon structural steel materials to withstand mechanical performance is poor, to meet some of the small carrying capacity of the place, 45 #, 40Gr and other materials, mechanical properties are relatively good, large carrying capacity, stainless steel chain Wheel materials in the pharmaceutical and chemical, food industry applications. Which forging rough production of different materials, then the mechanical properties will show different. Alloy steel, carbon steel and aluminum, copper and other alloys have good plasticity conditions, forging conditions better, but the cast iron is relatively poor plasticity, can not be forged.

      The second is heating

      Select the material of the sprockets of different adaptation temperature is not the same, mainly divided into three temperatures:

      Forging temperature range: the beginning of the forging of the temperature and the temperature range between the termination of forging.

      Initial forging temperature: the manufacture of metal parts to allow forging the maximum temperature, if the temperature control is too high, there will be thermal defects.

      Final forging temperature: shorten the minimum allowable temperature of early metal materials. If the final forging temperature control is too low, it will make forging more time-consuming, prone to fracture.

      Therefore, we say, for the choice of material forging temperature is more important. We can use the pyrometer or optical pyrometer to measure the temperature when heating; we can also determine the temperature by the "fire color" method, but this method will measure the temperature there is a certain error.

      A third suitable heating device

      Good heating device for the sprocket material changes in the internal structure plays an important role, under normal circumstances, the flame heating and electric heating is the two commonly used heating equipment, we can process the amount of processing materials and the choice of different heating equipment
