Spline shaft hardening by high frequency induction hardening machine

As a more important part of the car, the spline shaft needs to bear huge friction during the working process. For this reason, we often use 80kw high-frequency induction hardening machine for quenching heat treatment. The high-frequency induction hardening machine produced by Zhengzhou Gou's has complete functions and is easy to operate. It is not only popular in China, but also sold to Indonesia, Malaysia, Mexico, Vietnam, Belgium, Czech Republic, Russia and other countries and regions.

The spline part of the spline shaft needs to be quenched with a high-frequency induction hardening machine. The heating temperature is 860-900°C, and the water is sprayed for cooling. The workpiece must be rotated slowly to ensure uniform heating around the circumference of the workpiece. After the quenching heat treatment, the spline needs to be annealed.

Advantages of high frequency induction hardening machine

1. The heating speed is fast and the heating is uniform, (the speed can be adjusted and controlled).

2. Easy to install, just connect the power supply, induction coil and water inlet and outlet pipes; small size, light weight, easy to use.

3. The operation is simple and can be learned in a few minutes.

4. Eliminate high voltage, avoid the step-up transformer that generates nearly 10,000 volts of high voltage, and the safety is very high.

5. Wide heating, can heat all kinds of metal workpieces (replace the detachable induction coil according to the different working switches).

6. Quick start, heating can be started after water and electricity are turned on.

7. Less power consumption, about 70% less power than old-fashioned tube high-frequency equipment, the smaller the workpiece, the less power consumption.

8. Full protection, with alarm indications such as overvoltage, overcurrent, overheating, water shortage, etc., and automatic control and protection.

9. The effect is good, the heating is very uniform, the temperature rises quickly, the oxide layer is less, and there is no waste product after quenching.

10. The temperature is controllable, and the heating temperature of the workpiece is controlled by setting the heating time, so that the heating temperature can be controlled to a technical point.
