What is an induction quenching heating machine and what is its purpose?

In my country's industrial technology, the high-frequency quenching heating machine plays an important role, but it may be unfamiliar to unfamiliar friends, but it doesn't matter, it is not difficult to understand it, and I will come to it one by one. To solve it for everyone, let Kehua solve it for everyone. Introduction High-frequency quenching is mostly used for surface quenching of industrial metal parts. It is a metal heat treatment method that generates a certain induced current on the surface of the workpiece, rapidly heats the surface of the part, and then rapidly quenches it. Induction heating equipment, that is, equipment for induction heating of workpieces for surface quenching. The principle of induction heating: the workpiece is placed in the inductor, and the inductor is generally a hollow copper tube inputting intermediate frequency or high frequency alternating current (1000-300000Hz or higher). The alternating magnetic field generates an induced current of the same frequency in the workpiece. The distribution of this induced current in the workpiece is uneven, it is strong on the surface, but very weak in the interior, and it is close to 0 in the center. This skin effect is used. , the surface of the workpiece can be heated rapidly, the surface temperature rises to 800-1000 ℃ in a few seconds, and the temperature of the core part is very small. The principle of high-frequency quenching heating machine The high-frequency quenching heating machine places the workpiece in an inductor wound with a hollow copper tube. Local rapid heating (800~1000℃ in a few seconds, the heart is still close to room temperature), spray (immersion) water cooling (or spray immersion oil cooling) immediately after a few seconds to complete the immersion work, so that the workpiece surface or Locally meet the corresponding hardness requirements. High-frequency quenching heating machine application Heat treatment industry: 1. High-frequency quenching heat treatment for various steam and motorcycle parts, such as: crankshaft, connecting rod, piston pin, camshaft, valve, various gears in the gearbox, various forks, High-frequency quenching heat treatment for various spline shafts, transmission half shafts, various small shaft crank pins, various rocker arms, rocker arm shafts, etc. 2. High-frequency quenching heat treatment of hardware tools, such as vices, hammers, strong pliers, wrenches. 3. Hydraulic components such as: the plunger of the plunger pump, the rotor of the rotor pump, the reversing shaft on various valves, the gear of the gear pump, etc. are quenched by high frequency. 4. High-frequency quenching heat treatment of gear shafts of various power tools. 5. Various woodworking tools, such as: axes, planers and other heat treatment. Forging industry: 1. Steel plate heating, bending and forming. 2. Standard parts, heat forming of fasteners. 3. Heat diathermy for hardware tools, such as pliers, wrenches, etc. 4. Extrusion of the taper shank of the prospecting drill rod. 5. Steel pipe diathermy forming, such as pipe bending, etc. Brazing: 1. Welding of carbide tools. Such as turning tools, milling cutters, reamer. 2. Welding of diamond bits. Such as diamond saw blades, abrasive tools, sawtooth welding. Welding of drill bits for prospecting, such as the welding of straight-line drill bits and claw bits. 3. Brass, copper. High-frequency quenching heating machine Well, this is what Kehua explained to you about the high-frequency quenching heating machine and what it is used for. Among them, the high-frequency quenching heating machine is one of the important equipment in my country. It is used in various industries around us, contributes to the progress of industrial technology, brings benefits to us, and brings convenience to our lives.
