摘要：

锻造操作机夹钳旋转系统直接与钢锭接触，具有承受锻造载荷波动范围大、负载夹持扭矩大、旋转角位移控制精度高等特点，对夹钳旋转液压系统的合理设计及液压元件的恰当选型是提高锻造精度和锻造质量重要的途径和方法。基于100 t液压锻造操作机，依据设备工作性质，选定了液压系统的工作压力；通过对其机械结构及技术性能参数进行分析，确立了液压系统的设计方案，并在此基础上对液压原理图进行了详细设计；针对设备在不同工况下的工作特点及性能要求，通过关键参数的计算对主要液压元件进行了选型。设备使用结果显示，操作机夹钳旋转工作平稳，夹钳旋转定位精度达到±1°，旋转性能满足设计要求。

The clamp rotation system of forging manipulator is directly connected with steel ingot, which has the characteristics of large fluctuation range of bearing forging load, large torque of load holding, high control precision of rotation angular displacement and so on. Therefore, a reasonable design of clamp rotation hydraulic system and a proper selection of the hydraulic components are important to improve forging precision and forging quality. Based on 100 t hydraulic forging manipulator, the working pressure of hydraulic system was selected according to the working characters of the equipment. Then, the design scheme of hydraulic system was established by analyzing its mechanical structure and technical performance parameters, and the hydraulic schematic diagram was designed in detail. According to characteristics and performance requirements of the equipment under different working conditions, the main hydraulic components were selected by calculating key parameters. The results show that the operation of clamp rotation for the manipular is stable, and the clamp rotational positioning accuracy is ±1°. Thus, the rotation performance meets the design requirements.
