摘要：

根据锻造操作机钳口结构特点，将钳口夹持过程分为使锻件产生塑性变形挤压痕的夹紧状态和钳口承受锻件重力及重力矩并执行操作动作的夹持状态,并进行钳口夹持力理论分析。研究结果表明，影响夹持力大小的是夹紧状态的挤压作用，确定锻造操作机夹持力应以夹紧状态的作用力为依据。并以此为基础，分析了影响钳口夹紧力的因素，为优化钳口结构提供了条件。

According to the structure characteristic of forging manipulator jaw, the jaw's gripping process was separated into the clamping condition to make the plastic deformation extrusion mark on the workpiece and the gripping condition when supporting the gravity and heavy torque of the workpiece and performing the operating action to do a theoretical analysis on jaw's gripping force. The research results indicate that the gripping force is affected by the extrusion and the gripping force of the forging manipulator should be determined by the force of the clamping condition. Based on it, the factors affecting the jaw's clamping force were analyzed, and the conditions for the optimization of the jaw's structure were provided.
