Coil adjusting structure for induction heating device

Abstract

The invention relates to a coil adjusting structure for an induction heating device. The coil adjusting structure comprises a case and a heating coil installed at the case; an installing plate is fixedly installed at a front plate of the case; and the heating coil is installed at the installing plate by bolts. S-shaped bending sections is arranged at the middle sections of the bolts; and expansion sections are arranged at threaded inner sides of one ends, connected to the installing plate, of the bolts. A circular installing hole is arranged in the installing plate; a circular plate-shaped adjusting plate is clamped into the installing hole by a rotatable way; and a plurality of clamp groove holes are uniformly distributed at the inner wall of the installing hole along the periphery. Bolt holes are arranged at eccentric positions of the adjusting plate and the bolts are inserted into the bolt holes; clamp bolts are arranged at a radial direction between the inner wall of the bolt holes and the outer wall of the adjusting plate. According to the coil adjusting structure, the height and the inclined angle of the coil can be adjusted by one-time operation; the operation is convenient and can be learned easily; and the same device can be applied to coils with different sizes, so that the universality is high.

Description

technical field [0001] The invention relates to an electric heating device, in particular to a coil adjustment structure for an induction heating device. Background technique [0002] Induction heating is the use of electromagnetic induction to convert electrical energy into heat energy, and is often used in the field of heat treatment of metal parts. Put a coil around the metal conductor. When the alternating current is passed into the induction coil, the alternating magnetic flux will be generated in the induction coil, so that the workpiece in the induction coil is subjected to electromagnetic induction to generate an induced potential. The induction potential generates an induced current in the workpiece to start heating inside the workpiece, which is the basic principle of induction heating. The position of the induction coil in the traditional induction heating equipment is fixed. The disadvantage of this method is that the position and angle of the induction coil ma...

AI Technical Summary

Problems solved by technology

The position of the induction coil in the traditional induction heating equipment is fixed. The disadvantage of this method is that the position and angle of the induction coil may need to be adjusted due to the different positions of the workpieces to be heated.

The fixed induction coil cannot adjust the height or angle very well, and the heating position is limited, which affects the use effect. In order to improve production efficiency, the usual method is to make various coils with special shapes and different bending angles. The disadvantage of this method is The advantage is that the utilization rate and production efficiency of the coil are reduced

Another patent I applied for is "A Coil Adjustable Induction Heating Device". The patent application number is 2012205177023, which discloses an induction heating device with adjustable coil height and inclination angle. The slot and arc-shaped chute realize the adjustment of the height and inclination angle of the coil. Although this structure can realize the adjustment of the coil posture, its structure is complicated, the adjustment process is cumbersome, and its versatility is poor, so it is not convenient to use.
