Example Embodiment
[0056] The embodiment of the application discloses a forging process of a high-speed steel tool.
[0057] Reference figure 1 , A high-speed steel tool forging process, including the following steps:
[0058] S1. Prepare ingredients. Use a band saw to cut high-speed steel ingots to form blanks, the size of which is 20cm*20cm*15cm;
[0059] S2. Put the billet into the desktop heating furnace 1 for heating. The heating temperature is 500°C, and then the temperature is increased. The heating rate is controlled to be less than 80°C per hour, and then the temperature is kept at 850°C. This can increase the plasticity of the billet and reduce the billet. Anti-deformation ability, the blank can be easily formed, and good structure and mechanical properties after forging can also be obtained.
[0060] S3. Heat the preheated billet to a temperature of 1130~1180℃, put it into a forging die for forging to form the preliminary shape of the tool. The initial forging temperature is 1100~1150℃, the f...
