Quenching process of precision rack

Precision rack is a common accessory, do not look down upon it, it plays a great role, there is a lot of relevant knowledge about it, there are a lot of people do not understand it, such as its quenching process.

Let's take a look at the quenching process of the precision rack.

1. Operating characteristics: longitudinal and transverse composite magnetic field induction heating quenching, high heating efficiency, high speed, only 6 seconds / piece; uniform hardness distribution; small power consumption; the tooth edge and the middle part; the root quenching layer can be controlled; small deformation.

2, working principle: switch on the high-frequency power supply, the electric contact and the sensor are connected into the circuit, and the sample above the sensor becomes the induced heating body.

In this way, the surface of the workpiece is not only heated by the longitudinal magnetic field, but also heated by the transverse magnetic field, to achieve the purpose of uniform heating.

Replace different sensors, you can heat the surface of different shapes of the workpiece.

Compared with the traditional high-frequency heating, the workpiece surface heating current is more concentrated, more density, faster heating speed.

With this method, the power density of the surface of the heating workpiece is several times that of the traditional induction heating, and high-quality heat treatment can be implemented on the surface of the workpiece.

3, precision rack quenching process: put on the sensor, the cylinder down, press the rack, induction electrode, rack and sensor connected, the distance between the sensor and the rack can be adjusted according to the need.

The inductive current generated by the vertical and horizontal magnetic field hethe tooth surface at the same time, and the heating speed is very fast. The heating time is controlled. After the temperature is reached, the equipment stops heating and automatically sprays quenching liquid into the tooth surface to complete a quenching process.
