A worm refers to a gear that has one or several helical teeth and meshes with a worm wheel to form a cross-axis gear pair. During the working process, the worm is subjected to huge frictional force, therefore, the worm is usually required to have high hardness, high wear resistance and long service life in production. How to meet these requirements of the worm. After continuous experiments, people found that quenching heat treatment on the worm can effectively improve the hardness, wear resistance and service life of the worm.
In the past, people mostly used coal furnaces to quench and heat-treat worms. During the quenching process, a large amount of waste gas and smoke were produced, not to mention polluting the environment, and even the quenching effect was not good. There were always deformation, cracks, oxidation and decarburization, etc. Defects greatly affect the normal use of the worm. With the development of technology, IGBT medium frequency heating power supply came out. After many manufacturers use this equipment for quenching heat treatment, they find that the quenching effect is greatly improved, avoiding various defects caused by traditional heat treatment, and even the service life is 2-3 times that of traditional quenching.
The IGBT medium frequency induction heating power supply quenches the worm. The operation process is very simple. You only need to put the worm into the inductor and heat it to 800-900°C, and at the same time use the quenching medium to cool it. No other operations are required. Compared with traditional equipment, it saves a lot of time and effort.
