Background technique [0002] Quenching is an important heat treatment process, and disc parts (such as gears) have high requirements and large demand for quenching equipment due to their special structure and wide application. [0003] The bed frame of the traditional quenching machine tool is mostly fixed, which cannot be adjusted in a small range, thus limiting the adjustment space between the relative position of the part and the quenching sensor; usually, the idler rollers arranged on the frame are used to adjust the parts.

AI Technical Summary

Problems solved by technology

[0003] The bed frame of the traditional quenching machine tool is mostly fixed, which cannot be adjusted in a small range, thus limiting the adjustment space between the relative position of the part and the quenching sensor; usually, the idler rollers arranged on the frame are used to adjust the parts. The positional relationship between support and idler rollers is set in advance. This type of idler support is easy to cause slippage during the rotating quenching process of parts, especially large heavy-duty parts, and there are certain safety hazards. It is mainly used for fixed-size parts. It is more suitable, but for batch quenching of parts of different sizes, it is difficult to automatically adjust the clamping size function, and it is difficult to effectively control the clamping force applied to the parts. Too small a clamping force may easily cause slippage, and too large a clamping force It is easy to cause surface and internal damage to parts

[0004] Traditional quenching machine tools limit the quenching heat treatment of large quantities of parts with different structural parameters

In addition, the structural form of the quenching machine tool and the quenching process parameters have an important impact on the quenching effect of the parts, while the traditional quenching machine tool cannot determine the optimal rack bracket tilt angle, quenching speed and quenching process according to the material properties and quenching process requirements. Frequency and other key parameters; at the same time, the change of process parameters in the quenching process cannot be effectively monitored and adjusted in time, and it is difficult to ensure the quality of quenching, thereby reducing the efficiency, reliability and quality of quenching, and it is difficult to realize the intellectualization of the quenching process
