Abstract：

Based on the structural characteristics and control principles of parallel link type forging manipulator, the working status of the hanging system for forging manipulator was analyzed, and the buffer mechanism of forging manipulator was clarified. Then, the dynamic models were established based on the starting and braking conditions of forging manipulator, which provided theoretical support for optimizing the buffer performance of forging manipulator. Furthermore, combined with the buffer mechanism and the working status of forging manipulator, the influences of buffer cylinder and horizontal lifting cylinder on the buffer performance of forging manipulator were analyzed, and the role of horizontal lifting cylinder in the buffer device was clarified. Through the analysis of the stress state of buffer cylinder and the driving torque of horizontal lifting cylinder, the structural factors affecting the buffer performance of forging manipulator were proposed, the influences of the position relationships between the horizontal lifting of clamp rod and the buffer cylinder, horizontal lifting cylinder and front turret on the buffer performance were studied, the structural parameters of front boom and buffer cylinder were determined, and the inherent relationship of the key structural factors for the buffer device of forging manipulator was clarified, which provides the theoretical basis for the dynamic analysis and the hanging system structure design of forging manipulator.
