A worm rod 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 rod is subjected to huge friction and wears out quickly. For this reason, the production requires the worm rod to have high hardness, high wear resistance and high service life. In order to meet the needs of the work, many manufacturers use medium frequency induction hardening equipment for quenching heat treatment, and the effect is very good.
The worm rod is quenched and heat-treated by medium-frequency induction hardening equipment. The inductor is a copy sensor made according to the specifications of the worm rod, which ensures the uniformity of the quenching temperature and the quenching area of the worm rod, and makes the quenched worm rod surface have thicker toughness under the hard layer. The area has good compressive internal stress, which makes the fatigue resistance and breaking capacity of the worm rod higher, and the service life is 2-3 times that of non-quenching.
Medium frequency induction hardening equipment has multiple self-protection functions: overvoltage, overcurrent, water shortage, overheating, high frequency, low frequency, phase loss protection, etc. If there is any manual error during operation, the machine will automatically alarm immediately to protect its own life. After many manufacturers have used our equipment, the quenching effect of the worm rod is better than before. Not only the oxidation and decarburization phenomena are significantly reduced, but also the cracks and deformation defects are greatly reduced.
