The clamp rod mechanism is an important part of the forging manipulator. It is used to clamp forging to assist host in finishing forging process. It can complete the basic function of the forging manipulator, and its operation performance plays an important role in forging manipulator function. So it is very important to design and analyze the stability, safety and operation of the forging manipulator. This paper studys the structure form and function of the clamp rod mechanism of the forging manipulator, analyze the hydraulic control system and establish the hydraulic system model to make the further analysis of the clamping mechanism. The mechanical model of the forging manipulator and hydraulic control system are built by using virtual prototyping technology. The co-simulation of clamp rod rotating mechanism is completed by using ADAMS and AMESim interface technology. According to the different control modes of the hydraulic system, the position closed loop system and flow compensation position closed loop machine liquid system of the clamp rod rotating are simulated respectively. It shows that the closed loop control system of the rotary flow position feedback is more suitable for the control of the rotary motion of the pliers.
