Introduction to the working principle of high frequency quenching equipment for machine tools

High-frequency quenching equipment is often seen in some processing industries. This is a new type of processing machine and equipment with good working performance and cost savings. Let us and Kehua understand the price and working principle of machine tool high-frequency quenching equipment. Machine tool high frequency quenching equipment price 1. High frequency quenching High frequency quenching refers to the use of high frequency current (30K-1000KHZ) to locally heat and cool the surface of the workpiece to obtain a surface hardened layer. This method only strengthens the surface of the workpiece to a certain depth, while the core basically maintains the structure and properties before treatment, so a combination of high strength, high wear resistance and high toughness can be obtained. And because it is local heating, it can significantly reduce quenching deformation and reduce energy consumption. It is precisely because of the above characteristics of induction quenching that it is widely used in the machining industry. Second, the working principle and outstanding advantages of high-frequency quenching equipment using induction heating, the engineer explained the principle of induction heating is: the workpiece is placed in the inductor, the inductor is generally a hollow input medium frequency or high frequency alternating current (1000-300000Hz or higher) copper pipe. 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, and the surface temperature rises to 800-1000ºC in a few seconds, while the temperature of the core is small. Outstanding advantages of high-frequency quenching equipment 30% power saving, 20% power saving compared with thyristor intermediate frequency; good effect: very uniform heating (you can also adjust the density of the induction coil, so that each part of the workpiece can obtain the required temperature), fast heating, less oxide layer, No waste after annealing; fast heating speed: induction heating, no oxide layer, small deformation; small size: split structure, light weight, easy to move and install; environmental protection: no pollution, noise and dust; strong adaptability: can be heated A variety of workpieces; temperature and heating time can be precisely controlled, high processing quality. Full protection: There are alarm indications such as overvoltage, overcurrent, overheating, water shortage, etc., and automatic control and protection. Third, the price of high-frequency quenching equipment for machine tools High-frequency quenching machine ￥ 24,900.00 Do you understand, the best high-frequency quenching equipment on the market is produced by Kehua manufacturers, and the quality is very good.
