Quenching machine tools, as the name implies, generally refers to the use of induction heating power quenching process special machine tools. It has the advantages of high precision, good reliability, time saving and labor saving. It is mainly composed of bed, sliding table, clamping and rotating mechanism, cooling system, quenching liquid circulation system, electrical control system, etc. Quenching machine is usually single station (double position quenching machine can be used for small diameter workpiece). Quenching machine can be divided into vertical and horizontal structure. Users can choose quenching machine according to quenching process. For special parts or processes, special quenching machine tools can be designed and manufactured according to the requirements of heating process.
At present, in China's economic market, quenching machine tools are involved in textile, metallurgy, automatic production lines, CNC machine tools and other industrial production. The quenching machine has been widely used in the laboratory. It has high precision and intelligent control for quenching equipment. High power high frequency induction hardening machine drive, CNC knob type, stable operation, environmental protection and other features. It is an ideal equipment for scientific research institutions, universities and medical institutions in product development, quality control and production process. It has the functions of fast switching speed, optical isolation, fault state feedback, configurable automatic reset and automatic shutdown. Therefore, it is a clear choice to choose quenching machine as the driver of IGBT. Induction heating is based on the principle of electromagnetic induction, using the heat generated by eddy current in the workpiece to heat the workpiece. Induction heating is widely used in smelting, casting, bending, hot forging, welding and surface heat treatment industries because of its high efficiency, fast speed, good controllability, easy to realize high temperature local heating, easy to realize mechanization and automation. In foreign countries, induction heating technology is more and more mature. In terms of casting, the double melting process has developed rapidly, that is, the medium frequency furnace is used for precision casting of nodular cast iron or alloy steel; in the forging process, induction heating is used to realize rapid non adiabatic forging; at home and abroad, we are committed to developing high-power solid-state high-frequency power supply, on the one hand, we are committed to developing highly automated heat treatment system. unified. High quenching efficiency: the double rail can be quenched about 200 ~ 400mm / min; if the guide rail surface is too wide, the inductor can be quenched on one side; if the guide rail surface is narrow, it can be quenched at one time on both sides; multiple quenching methods: continuous scanning quenching, simultaneous quenching, segmented continuous scanning quenching and segmented simultaneous quenching can be realized; environmental protection: no pollution, noise and dust. The electric control system of machine tool reserves the control interface of quenching heating and cooling water. The quenching process and cooling process can be controlled according to the process requirements.
