Heat Treatment of Bicycle Center Axle by High Frequency Induction Heating Equipment
Latest company news about Heat Treatment of Bicycle Center Axle by High Frequency Induction Heating Equipment

As a kind of sports equipment, a bicycle has the characteristics of light weight, lightness, safety and comfort. In addition, it requires the design of the overall structure and parts, and the selection and processing of materials should ensure that it has sufficient strength, good rigidity and wear resistance.

 

The central axle is one of the main transmission parts in the bicycle, and it is the main force-bearing part. It is not only affected by the impact force, but also in contact with the ball bearing to transmit power. The failure mode in normal work is the peeling and wear of the outer layer caused by low-load contact fatigue, so the surface of the central axis should have high hardness to resist wear, and at the same time, high fatigue strength is required, and its own strength and toughness. Therefore, according to the working characteristics of the central axle, it is necessary to perform a heat treatment process on the bicycle central axle through high-frequency induction heating equipment.

 

In the process of high-frequency induction heating equipment for the heat treatment of the central shaft, the specific technical requirements are: the carbon content is 0.8%-1.0%; the depth is 0.7-1.0mm; the surface hardness is 80-83HRA; the microstructure is Martens The body grade is less than grade 4, no obvious carbides appear, and it is distributed on the basis of the martensite in a small, uniform and round form; good toughness (not broken during straightening) and small distortion (bending <0.3mm) .The subsequent heating is water-cooled after reheating. It can be heated as a whole or locally, and then heated at a low temperature. The surface of the central axis after heat treatment has obtained high hardness and has good comprehensive mechanical properties inside.
