What are the typical structures of induction heating equipment inductors?

The characteristic of the inductor of induction heating equipment is that the conductive part of the effective coil is relatively thick, and the structure is relatively heavy. Generally, it is welded and assembled by multiple machined parts. Some inductors are also equipped with a workpiece positioning device. At this time, it is not necessary to rely on the quenching machine tool. Rotate loading work.

1. The induction heating equipment has a semi-annular crankshaft sensor: it is composed of multiple parts such as an effective ring, a spacer block, a side plate, a liquid sprayer, and a spacer block. Its core is the effective ring, which branches in the circumferential direction and axially Composed of branches.

2. The induction heating equipment has a longitudinally heated shaft-type semi-annular inductor: it is a kind of inductor used for primary heating and quenching of straight shafts, stepped shafts, and half shafts that has been widely used in the late 1960s.

3. Camshaft quenching inductor: Because of its special geometric shape, the current frequency used has a decisive effect on the temperature of the tip. There are two types of cam sensors: circular ring and profiling. Engine cam sensors mostly use circular effective rings.

4. Inductor for quenching the inner surface of the cylinder liner: The inner surface of the cylinder liner is quenched by scanning quenching. Due to the thin wall of the cylinder liner, when the inner surface is heated and quenched, there is an auxiliary sprayer cooling on the outer surface of the cylinder liner, which can reduce the cylinder liner. Deformed.

5. The induction heating equipment has a short cylinder heating inductor: it is an inductor that heats a short cylinder workpiece. The effective circle is divided into three layers. The upper layer heats the upper section, the middle layer heats the middle section, and the lower layer heats the lower section. Adjust the wrap angle of each section to adjust the temperature of each section. The effective ring of this structure can also be equipped with magnets according to the requirements of different workpieces, and the lowermost effective ring can be slightly modified to heat the rounded corners and flange surface of the workpiece.

6. Bell-shaped shell spline heating inductor: its effective ring is divided into three sections, the upper section heats the upper end of the workpiece cylinder, and the middle section is heated by two uprights. The upright should be equipped with a conductive magnet; down forged heating shaft The part of the magnet can also be added.

7. The induction heating equipment has a half-shaft primary heating inductor: a high-power intermediate frequency power supply is used to harden the hardened area of ​​the half-shaft at one time. In addition to improving productivity, this method can also be combined with a special quenching machine tool to combine heating, correction, and cooling on a quenching machine tool.
