Bearing sleeve heat treatment device and heat treatment method
By designing a synchronous clamping device that utilizes the self-weight of the ring forging, multi-layer stacking and coaxiality maintenance of the ring forging during the heat treatment process were achieved. This solved the problems of unstable fixation in the suspended state and poor reliability under high temperature conditions, thereby improving heat treatment efficiency and product quality.

AI Technical Summary
In the existing technology, the ring forgings lack effective fixation in the suspended state during the heat treatment process, resulting in a limited number of pieces that can be lifted at one time, making it difficult to maintain coaxiality and interlayer connection reliability. Furthermore, the existing clamping devices require external power to drive them, which leads to poor reliability in high-temperature environments.
A bearing sleeve heat treatment device is adopted, including a moving mechanism and a fixing mechanism. The device utilizes the self-weight of the ring forging to achieve synchronous clamping, fixing the outer and inner walls simultaneously. Through the cooperation of the main lifting component and the auxiliary lifting component, multi-layer stacking is achieved, and the device is driven by pure mechanical self-weight to avoid damage to hydraulic or pneumatic pipelines at high temperatures.
This technology enables multiple workpieces to be hoisted and stacked in multiple layers at once, improving heat treatment efficiency, ensuring the coaxiality of the workpieces and the reliability of interlayer connections, reducing the labor intensity of operation and the complexity of equipment, adapting to high temperature and high humidity environments, and improving safety and product quality uniformity.
