Quenching machine As the name implies, it generally refers to the use of induction heating power in the quenching process of special machine tools. It is mainly composed of bed, sliding table, clamping and rotating mechanism, cooling system, quenching liquid circulation system, electrical control system, etc. Quenching machine tools are generally single station. There are two kinds of quenching machine: vertical and horizontal. Users can choose quenching machine according to quenching process. For special parts or special process, special quenching machine can be designed and manufactured according to the requirements of heating process.
Quenching machine 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. Because quenching machine tool can improve the wear resistance, fatigue strength and toughness of metal parts, reduce the emission of carbon dioxide, clean and environmental protection, and realize high production efficiency by short time heating Rate, very energy saving, heat preservation treatment and quenching have been widely concerned by the industry.
Dual frequency induction hardening plays an important role in medium and large rolls. It increases the quenching depth, surface hardness, yield strength, fracture strength, plasticity and toughness of steel, and improves wear resistance and accident resistance of rolls. The main body of machine tool has distinct characteristics. The roller lifting mechanism, balance mechanism, workpiece rotation mechanism, quenching mechanism and temperature measurement system are fixed on the quenching machine tool. The roller is installed at the upper end of the middle crossbeam. The middle crossbeam is moved by the lifting mechanism, and the lower end of the workpiece is arranged in the middle. The spiral guide rail runs accurately and the roll positioning is accurate. The lower crossbeam is fixed with stainless steel pull rod through the automatic locking mechanism, so that the middle and lower crossbeam (not in water during operation and not shown in the figure) can move together to ensure that the workpiece rotates along the upper and lower upper axes. In addition, a set of lifting tools matching with the top is designed for loading and unloading rollers. The main part of the machine tool covers a small area, and the main control room is set on its side for the installation of electrical cabinet, which integrates PLC, AC servo device, various digital instruments and control buttons, touch screen and industrial computer; the electrical room is set behind the machine tool, including high-voltage substation, medium frequency power supply and other equipment; various water-cooled motor equipment outside the plant. The whole set of equipment has compact structure and reasonable layout.
