A. Composition of quenching machine tool

It is mainly composed of three parts: quenching machine tool, intermediate frequency power supply (high frequency power supply, super audio power supply, ultra high frequency power supply), and cooling device; among them, the high frequency quenching machine tool consists of bed, upper and lower clamping mechanism, clamping rotating mechanism, and quenching transformer It is composed of resonance tank circuit, cooling system, quenching liquid circulation system, electrical control system, etc. The quenching machine is generally single station (double station quenching machine can be used for small diameter workpieces); the quenching machine has vertical and There are two types of horizontal, users can choose quenching machine tools according to the quenching process, and for special parts or special processes, special quenching machine tools can be designed and manufactured according to the heating process requirements.　　B. Uses of quenching machine tools:

The quenching machine tool cooperates with the intermediate frequency power supply (high frequency power supply, super audio power supply, ultra high frequency power supply) to realize the induction hardening process controlled by the PLC program. It is commonly used for gears, bearings, shaft parts, valves, cylinder liners and various types Quenching and heat treatment of mechanical parts.

D. Edit this paragraph commonly used quenching equipment type

1. External quenching series: the external surface of various shafts, rods, tubes and round parts (such as bearings, valves, etc.) is quenched integrally or partially.

2. Inner circle quenching series: quenching the inner circle of all kinds of pipes and mechanical parts, such as cylinder liners, shaft sleeves, etc., either integrally or partially.　　3. End face and plane quenching series: the end face and plane part of mechanical parts are quenched integrally or partially.

3. Special-shaped parts quenching series: the whole or partial quenching of a certain surface of special-shaped parts.

4. Extra-large parts quenching series: the overall or partial quenching of large-volume and heavy-weight extra-large parts, such as marine gears, dam gate rails, large oil pipelines, etc.

6. Mould surface hardening series: Mould surface induction hardening machine tool is a kind of numerical control process equipment suitable for heat treatment of large-scale automobile panel molds and large non-circular space curved parts.
