Application scope and characteristics of high frequency induction hardening machine tool 09-30, 2019
In general, the quenching machine tool is a special machine tool with induction heating power supply. It has the advantages of high precision, good reliability and labor saving. The quenching machine is mainly composed of machine tool, clamping and rotating mechanism, cooling system, quenching circulation system, electrical control system, etc. generally, quenching machine tools are single station, and there are two types of quenching machines in structure: vertical and horizontal. Users can choose different types of quenching machines according to the quenching process.
Because quenching machine can improve the wear resistance, fatigue strength and toughness of metal parts, reduce carbon dioxide emissions, clean and environmental protection, short time heating can achieve high production efficiency, very energy saving, heat preservation treatment and quenching have been widely concerned by the industry. IGBT should be used as switch device in heating power supply, and its working frequency range is 10hz-10khz. Quenching machine is composed of rectifier, filter and inverter. The filter consists of two electrolytic capacitors and one inductor. The filter includes type II filter and passive power factor correction. At present, in the textile, metallurgy, automatic production line, CNC machine tools and other industrial production, has been involved in high-frequency induction hardening machine tools.
High frequency induction hardening machine is widely used in laboratory equipment. The practical quenching equipment has high precision and intelligent control. High frequency induction hardening machine is an ideal equipment used in product development, quality control and production process in scientific research institutions, universities and medical institutions. The system has adjustable working frequency, adjustable dead time, input under voltage locking function and double output current. It has the functions of fast switching speed (500 NS), optical isolation, fault state feedback, automatic reset, automatic shutdown and so on, so it is selected as the driver of IGBT.
Energy saving transformation of high-frequency quenching equipment not only saves a lot of money, but also avoids the waste caused by scrapping the old high-frequency quenching equipment. Therefore, the technical transformation of high-frequency quenching equipment is also an important link for enterprises to increase income and save expenses.
