When the high-frequency induction heating equipment quenches the concave spherical surface of the blade connecting seat, how should the sensor be designed?

The blade connecting seat is a key part on large construction machinery. The main functional components such as the blade mainly rely on this part to achieve universal movement. Therefore, the working conditions of the forklift connecting seat are quite harsh. Therefore, the concave spherical surface of the connecting seat High wear resistance and strength are required, so we need to use high-frequency induction annealing equipment to quench the concave spherical surface, but the sensor is a relatively difficult problem to solve. Today, Zhengzhou Gou's technical staff will talk about how to design the inductor for high-frequency quenching of concave spherical surfaces.

Different from the general induction heating situation, high-frequency induction heating equipment needs to use the outer ring of the inductor as an effective heating part to scan and heat the inner ring (concave spherical surface) of the workpiece for induction heating of the concave spherical surface. According to the working principle of induction heating, high-frequency current has a ring effect, that is, it tends to the inner ring surface of the ring-shaped inductor. This characteristic is not conducive to scanning and heating of the inner ring surface of the workpiece.

In order to overcome this unfavorable characteristic, achieve scanning heating of the inner ring (concave spherical surface) of the workpiece and improve heating efficiency, Zhengzhou Gou's designed and manufactured a concave spherical scanning part with a special structure based on years of practical experience. In order to improve heating efficiency, the special inductor for heating and quenching has the following structural characteristics:

1. The second turn of the effective heating part of the sensor is at an angle of 45° to the scanning direction, and is equipped with a row of water spray holes. During the scanning heating process, the heated area is quickly sprayed and quenched with liquid.

2. The effective heating section consists of two turns of coils in the same direction

3. The shape of the coil is an imitation concave spherical surface, and a "II" shaped magnet is applied to the inner ring of the coil to drive the high-frequency current to concentrate on the surface of the outer ring of the coil.
