The clamp rotation system of forging manipulator is directly connected with steal 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 im- prove forging precision and forging quality. Based on 100 t hydraulic forging manipulator, the working pressure of hydraulic system was se- lected 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 se- lected by calculating key parameters. The results show that the operation of clamp rotation for the manipular is stable, and the clamp rota- tional positioning accuracy is ±1°. Thus, the rotation performance meets the design requirements.
