The rotating shaft is an important part of machinery such as automobiles, and it must bear huge friction during the working process. Therefore, we should improve its surface wear resistance and hardness. We think that the most effective way to improve surface wear resistance and surface hardness is to use high-frequency induction hardening machine to perform surface quenching heat treatment. After quenching, there will be a 2-2.3mm hardened layer on the surface of the rotating shaft, and the hardness will reach 60-65HRC. , the service life is 2-3 times that of non-quenching.
High-frequency induction hardening machine is a high-tech product based on modern and advanced power electronic technology theory, which selects power electronic devices from more manufacturers in the world, and is produced with strict technical requirements. It has great advantages in quenching heat treatment of rotating shafts. advantages, as follows:
1. The quenching speed is fast, and the required temperature can be reached in a few seconds, which avoids the occurrence of oxidation and decarburization, and ensures the quenching effect of the rotating shaft.
2. After quenching, the surface hardness of the rotating shaft is high, the notch sensitivity is small, and the impact toughness, fatigue strength and wear resistance are greatly improved, which is conducive to exerting the potential of the material, saving material consumption and improving the service life of the parts.
3. The rotating shaft can be partially quenched or overall quenched, which can meet the requirements of different customers.
4. The equipment can not only be used for surface quenching of parts, but also for inner hole quenching of parts, which is impossible for traditional equipment.
5. The working environment is good, without noise and dust, and has been well received by workers.
6. Fast heating speed, high production efficiency and low scrap rate.
Having said so many advantages of the high frequency induction hardening machine in the quenching of the rotating shaft, it is impossible to justify the selection of the model. How to choose the model? We mainly consider how much equipment to choose according to the diameter, length and quenching depth of the rotating shaft. If the length is too large, we need to use CNC quenching machine tools to complete the quenching heat treatment.
