双偏心曲轴驱动摆式飞剪动态特性分析及应用

Dynamic Property Analysis and Application on Double Eccentric Crankshaft Driven Swing Type of Flying Shears

分析了摆式飞剪机构的结构特点和运动规律,针对确定的上剪刃位置和刀架质心位置,对上剪刃的速度和刀架对曲轴转动中心的等效转动惯量进行了分析,得到了一个普遍的计算通式,可以为确定曲轴转速和输入功率提供简便的计算方法。

Structural features and operation rule of swing type of flying shears have been described. Regarding to the certain upper cutting edge position and toolpost centroid location, the upper cutting edge speed and equivalent run- ning inertia of crankshaft center of rotation by toolpost have been analyzed, finally a universal calculation general ex- pression has been obtained, which could provide simple calculation method for crankshaft rotation speed and input pow- er determination.
