Induction heating coil applied to hot-charging knife handle

Abstract

The invention discloses an induction heating coil applied to a hot charging knife handle. The induction heating coil comprises a wrapping post made of a high-temperature-resistant material with a certain taper, a plurality of strands of polyurethane round copper stranded wires, a magnetic field gathering groove, a magnetic field gathering cover, an overheating protection module, a work indicatinglamp and the like. According to the invention, the induction heating coil achieves the non-contact heating of the knife handle through the electromagnetic induction principle, and the coil adopts a special winding structure, a special magnetic field gathering part and an assembling structure, so that the generated magnetic field is gathered at the middle upper part of the coil, and the heating section of the knife handle is gathered at the top, thereby smoothly realizing hot charging and taking out of a cutter by the cutter handle, greatly improving the heating efficiency and shortening the hot charging and taking-out time of the cutter.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to the design of an induction heating coil applied to a shrink-fit tool handle. Background technique [0002] The development level of the manufacturing industry is one of the important criteria to measure the comprehensive strength of a country. The main industrial sectors of the modern manufacturing industry include: energy industry, automobile industry, aerospace industry, military industry, electronics industry and mold industry, etc. The processing technology involved is mainly the cutting processing technology in which the tool removes the material. With the rapid development of modern manufacturing industry, it is proposed that cutting processing technology must have the characteristics of high speed, high precision and high efficiency. Therefore, based on the development of high-speed CNC center, high-performance cutting tools and coating technology...

Problems solved by technology

These international toolholder shrink-fitting devices are advanced in technology and have good matching performance with self-branded shrinkable toolholders, but the price is also very expensive, and due to reasons such as technical secrecy and international competition, it is almost impossible to see these international well-known knife manufacturers. Disclosure of design and manufacturing technology, basic common technology and theory of heat-shrinkable tool holders, heat-fitting devices and heating coils for key components

[0007] At present, researchers at home and abroad mainly study the influence of coil current and frequency changes on the heating performance, and the research on the influence of different winding methods of copper stranded wires, cross-sectional areas of copper wires and spacing between copper wires on heating is rarely involved. According to the size and shape of the tool handle, the principle of thermal loading and removal of the tool, the heating coil is designed so that the magnetic field generated by the coil should be concentrated in the middle and upper sections of the coil as much as possible, and the research on heating the middle and upper sections of the tool handle as much as possible is rarely involved.

At present, there is no equipment research and development report on the tool handle thermal charging device in China. The research and development of the tool handle thermal charging device with independent intellectual property rights will fill the gap in the domestic mechanical processing tool handle thermal charging device, and greatly promote the development of high-speed precision machining technology in my country. The heating coil in the handle shrink-fitting device is a key component and a difficult point in design
