High-frequency machine is the equipment used in many metal processing industries. High-frequency machine has been used in many industries. The main reason is that this kind of high-frequency machine is very energy-saving and environmentally friendly. Follow Kehua to understand the actual situation of Guangzhou high-frequency machine. use. Guangzhou high-frequency machine 1. High-frequency machine The high-frequency machine is currently the induction heating equipment with the highest heating efficiency, fastest speed, low consumption, energy saving and environmental protection for metal and non-metallic materials. The full name of high-frequency machine is 'high-frequency induction heating machineHigh-frequency induction heaters (welders), etc., as well as intermediate frequency induction heating equipment, ultra-high frequency induction heating equipment, etc. The application range is very wide. 2. Working principle 1. The high-frequency and large current of the high-frequency machine flows to the heating coil (usually made of copper tube) that is wound into a ring or other shapes. As a result, a strong magnetic beam with an instantaneous change in polarity is generated in the coil. When a heated object such as a metal is placed in the coil, the magnetic beam will penetrate the entire heated object, and in the opposite direction of the heating current inside the heated object, it will generate Correspondingly large eddy currents. Due to the existence of resistance in the heated object, a lot of Joule heat will be generated, and the temperature of the object itself will rise rapidly. To achieve the purpose of heating all metal materials. 2. A set of unique electronic circuits in the high-frequency machine convert the low-frequency alternating current of 50Hz input from the external power supply into high-frequency alternating current above 20000Hz; after the high-frequency current is added to the inductance coil, it is converted into high-frequency by the principle of electromagnetic induction. The magnetic field acts on the metal object in the magnetic field; the eddy current effect is used to generate an induced current in the metal object that is proportional to the magnetic field strength. When the current flows in the metal object, it will rely on the inherent resistance value inside, The heat is generated by using the principle of current heating effect. This heat is directly generated inside the object. Therefore, this heating method has high speed and high efficiency. If needed, it can melt any metal in an instant. Moreover, its heating rate and temperature are controllable. 3. Practical use Heating 1. Hot forging mainly heats the metal workpiece to a certain temperature (the heating temperature is different according to the material), and then forges the workpiece into other shapes by punching, forging or other forms. For example: watch case, watch embryo, handle, mold accessories, kitchen tableware, handicrafts, standard parts, fasteners, machining of mechanical parts, copper locks, rivets, steel brazing, hot extrusion of brazing tools, etc. 2. Hot fitting mainly refers to the connection between different metals or between metals and non-metals by heating the metals, using the principle of thermal expansion or thermal melting. For example: the copper core of the computer radiator and the aluminum sheet, the buried value welding of the speaker mesh, the compounding of the steel-plastic tube, the sealing of the aluminum foil (toothpaste skin), the motor rotor, the sealing of the electric heating tube, etc. 3. Smelting It mainly refers to converting metal into liquid through high temperature of metal. It is mainly suitable for iron, steel, copper, aluminum, zinc and various precious metals. Such as the melting of gold and silver. Heat treatment It mainly changes the hardness of metal materials by heating the workpiece and other treatments. The specific applications are as follows: 1. Various hardware tools and hand tools. Such as quenching of pliers, wrenches, hammers, axes, screwdrivers, scissors (garden scissors), etc.; 2. Various auto and motorcycle accessories. Such as quenching of crankshaft, connecting rod, piston pin, sprocket, aluminum wheel, valve, rocker shaft, transmission half shaft, small shaft, fork, etc. 3. Various power tools. Such as gears, shafts; 4. Machine tool industry. Such as the quenching of machine bed surfaces, machine tool guide rails, etc.; 5. Various hardware metal parts, machined parts. Such as quenching of shafts, gears (sprockets), cams, chucks, fixtures, etc.; 6. Hardware mold industry. Such as quenching of small molds, mold accessories, mold inner holes, etc.; Guangzhou high-frequency machine application process Kehua introduced the practical use of Guangzhou high-frequency machine, high-frequency machine is now used in the processing of many metal parts and auto parts, it is very important A popular new type of machine equipment.
