摘要
为了研究450 t双偏心曲柄摆式飞剪剪切过程的运动规律,应用三维建模软件Solidworks建立的摆剪各主要部件的实体模型并装配,而后进行运动学仿真。研究了剪刃的运动轨迹,重点对上下剪刃的速度和轧件速度的匹配情况进行分析,找到了双偏心主轴初始相位角的合理值;详细分析了剪切过程。分析发现：当双偏心轴的启动相位角为45°时,在0.472 5-0.577 5 s内,剪刃的水平速度大于轧件速度且垂直速度最大;剪切过程在该区间内完成,0.485 s时剪切开始,0.535 s时剪刃间隙为0。
To study the movement of the shearing process of 450 t couple off-center flying shear,the three-dimensional modeling of main components of flying shear is built using software Solidworks and then kinematics simulation is done. The trajectory of shear blade is studied. The velocity matching situation of the up / down shear blade and the rolled piece is emphatically analyzed,then the reasonable starting phase angle of the eccentric shaft is found. Shear process is analyzed in detail. Analysis found that when the starting phase angle of the eccentric shaft is 45°,the horizontal velocity of shear blade is larger than the rolling piece between 0. 472 5 s to 0. 577 5 s. Shearing process completed in the interval that the cutting begins at 0. 485 s and the blade gap is 0 at 0. 535 s.
