Induction coil heating device

Abstract

The invention discloses an induction coil heating device. The induction coil heating device is provided with an induction electromagnetic heating group, the induction electromagnetic heating group isprovided with a coil channel, the induction coil heating device is further provided with a working turntable, and the working turntable can bear a plurality of screws to be machined to sequentially pass through the coil channel; the induction electromagnetic heating group generates a high-frequency electromagnetic field at the coil channel by applying a high-frequency current, so that the passingscrew can be heated due to the electromagnetic effect; only the part to be heated of the screw is positioned in the coil channel, and the specific part of the screw can be accurately focused and heated by the high-frequency electromagnetic field, so that only a thread part to be heated can be accurately heated, another procedure can be executed after heating is completed, the screw can be accurately heated, the surface of the screw can be prevented from being carbonized or blackened, and the product quality can be kept.

Description

technical field [0001] The invention relates to a heating device, especially an induction coil heating device which uses electromagnetic to generate high temperature to heat a part of a workpiece. Background technique [0002] In the process of heating the workpiece in the prior art, the heating device has various structural types. During heating, the heat source and the workpiece to be processed are usually brought close to each other, so as to heat the workpiece. This kind of heating device is used to heat the workpiece. When it is used in the production and processing of screws, for example, to manufacture screws with specific leak-proof or anti-loosening functions, before applying glue to the specific parts of the screws with threads, heating is usually used. The device preheats or heats the screw before applying glue, so that the glue and the screw can have a more effective mutual bonding strength. [0003] The current heating process is to pass the whole screw through...

AI Technical Summary

Problems solved by technology

[0003] The current heating process is to pass the whole screw through the heating device. At this time, the heat source of the heating device heats the whole screw to increase the temperature. There are many kinds of heating devices, whether it is a flat-plate heating device, or It uses a ring-shaped heating device, which preheats or heats the screw as a whole. Therefore, both the rod body and the screw head and threaded parts at both ends are heated to a certain high temperature at the same time. The screw body and screw head After the part is subjected to high heat, the surface of the screw will have defects such as easy carbonization or scorched black.
