建立了广义肘杆机构的运动学和静力学模型。通过对其进行运动分析,可以看出该机构运动速度和加速度都很平稳,非常适合冷锻作业的需要。通过对该机构的静力分析,获得了该机构在不同工作条件下各杆的受力和偏心轴所需输入扭矩的变化规律,为各杆的强度设计和离合器的选择提供了依据;同时考虑到压力机在工作中可能出现的过载情况,对该情况下可能出现的离合器打滑和闷车也进行了深入的分析。分析发现,该广义肘杆机构冷锻压力机不会出现闷车情况。
The kinematics and statics model of generalized toggle mechanism is established. Through the analysis of its movement, it can be seen that the movement speed and acceleration are very smooth, which is very suitable for cold forging operations needs. Through the static analysis of the mechanism, the changing rules of the force and the input torque required by the eccentric shafts under different operating conditions of the mechanism were obtained, which provided the basis for the strength design of each rod and the selection of the clutch. At the same time, To the press in the work may occur overload situation, in this case may occur clutch slip and boring car also carried out in-depth analysis. The analysis found that the generalized toggle mechanism forging presses will not appear boring car situation.
