Description

Technical Field

[0002] High-frequency welding machine is a welding device used for various metal materials. The working principle of high-frequency welding machine is to use the principle of electromagnetic induction to convert into a high-frequency magnetic field and act on the metal object in the magnetic field; using the eddy current effect, an induced current proportional to the magnetic field strength is generated in the metal object. This eddy current is affected by the skin effect. The higher the frequency, the more concentrated it is on the surface of the metal object. When the eddy current flows in the metal object, it will generate heat by using the principle of current thermal effect with the help of the inherent resistance value inside. This heat is generated directly inside the object. Therefore, the heating speed is fast and the efficiency is high. It can melt any metal object instantly. Moreover, the heating speed and temperature are controllable. The welding head used in the existing high-frequency welding machine will generate a lot of heat when working. In order to prevent the high temperature from damaging the welding head after long-term use, it needs to be cooled. Therefore, how to cool the welding head is a problem that technicians in this field need to solve urgently. Utility Model Content
