High-frequency machine heat treatment, it is mainly through the workpiece after heating treatment makes metal hardness changes, specific applications are as follows: 1, all kinds of hardware tools, hand tools. Such as pliers, wrenches, hammers, axes, screwdrivers, scissors (gardening shears), etc. quenching; 2, a variety of automotive, motorcycle accessories. Such as crankshaft, piston pins, sprockets, aluminum wheels, valves, rocker shaft, drive axle, a small shaft, fork, etc. quenching; 3, various power tools. Such as gears, axes; 4, the machine tool industry category. As quenching machine bed, Machine Tool, etc.; 5, various hardware metal parts, machining parts. Such as hardened shaft, gear (chain wheel), cam, chuck and fixtures; and 6, the metal mold industry. The quench small molds, mold accessories, mold hole, etc; high frequency machine is the most efficient heating of metal materials, fastest, low energy saving type of induction heating equipment. Frequency machine full name of "high-frequency induction heating machine", also known as high-frequency heating machine, high frequency induction heating equipment, high frequency induction heating equipment, high-frequency heating power, high frequency power, high frequency welding machines, high frequency induction heating machine, High frequency induction heater (welding) or the like, in addition to induction heating equipment, ultra-high frequency induction heating equipment. Wide range of applications. High frequency machine is a high-frequency devices collectively for all high frequency machine manufacturers, one is heating the metal material, and the other is heated non-metallic materials. Use can be used pure or contain any hard and soft PVC film sold more than the 30% PVC special-purpose high-frequency machines, leather or fabric can be processed. The principle of the workpiece into the high-frequency inductor (coil) high frequency machining, when the sensor leads to a certain frequency of the alternating current, which produce an alternating magnetic field around. Electromagnetic induction alternating magnetic field causes induced currents closed within the workpiece - vortex. Induced current distribution in the cross section of the workpiece is not uniform, the workpiece surface current density is high, inward gradually decreased, a phenomenon known as the skin effect. Workpiece surface high-density currents of electricity into heat, so that the surface temperature of the high-frequency machine, namely to achieve surface heating. Current higher the frequency, the workpiece surface and internal current density difference is greater, the heating layer thinner. Rapid cooling in the heating surface temperature exceeds the critical point temperature of the steel, the surface hardening can be realized.
