What are the energy-saving models of high-frequency quenching machines?
High-frequency quenching machine can manufacture different metal workpieces, and there are many types of high-frequency quenching machines, such as outer quenching, inner quenching, special-shaped parts, etc. They are all equipment developed for more different processing parts. High-frequency quenching machine model Commonly used quenching equipment types: External quenching series: the overall or partial quenching of the external surface of various shafts, rods, tubes, circular parts (such as bearings, valves, etc.). Inner circle quenching series: The inner circle of all kinds of pipes and mechanical parts is quenched as a whole or partially, such as cylinder liners, shaft sleeves, etc. End face and plane quenching series: perform overall or partial quenching on the end face and plane part of mechanical parts. Special-shaped parts quenching series: perform overall or partial quenching on a certain surface of special-shaped parts. Extra large parts quenching series: perform overall or partial quenching on large and heavy parts, such as marine gears, dam sluice rails, large oil pipelines, etc. Kehua mold surface hardening series: mold surface induction hardening machine tool is a CNC process equipment suitable for heat treatment of large-scale automobile cover molds and large-scale non-circular space curved parts. Heating principle of high-frequency quenching machine model: Kehua high-frequency quenching machine adopts induction heating. The engineer explained that the principle of induction heating is: the workpiece is placed in the inductor, and the inductor is generally input with intermediate frequency or high frequency alternating current (1000-300000Hz or higher). ) of the hollow copper tube. 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 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 rises very little. Types of high-frequency quenching: Modern high-frequency quenching machines are more power-saving, energy-saving, efficient and environmentally friendly than traditional quenching machines. It can be divided into the following categories: 1. High-frequency induction gear should be heated and quenched: This type is specially used for quenching of various gears. After this process, the gears are more durable and wear-resistant. 2. High frequency induction heating shaft quenching machine: This type is specially used for surface quenching of various shafts, which will increase the hardness of the shaft surface and make it durable and wear-resistant. 3. High-frequency machine tool guide rail quenching induction heating machine: This type is specially used for guide rail quenching such as single guide rail quenching, double guide rail quenching, plane guide rail quenching, etc. Common high frequency quenching machine models can be produced, shafts, rods, tubes, round parts, and pipes, and the inner circle of mechanical parts can be quenched in whole or in part, such as some cylinder liners, shaft sleeves, etc.
