【摘要】:通过对国内外现有的液压板材剪切机结构的原理分析,提出一种新型的单液压缸驱动的液压滚切式板材剪切机,获得PR-11RⅢ级杆组的复合连杆机构简化模型。以实现纯滚动剪切为设计前提,利用闭环矢量法对该复合连杆滚切机构进行正运动学建模,给出机构的闭环矢量,推导其运动学方程,借助MATLAB/Simulink软件对其进行运动学仿真分析计算,获得上刀台各关键点的运动轨迹及主要衡量指标。以推广应用的某大型机械有限公司2 000 mm单液压缸驱动的液压滚切式板材剪切机研发项目为依托,对剪切机构的运动轨迹进行运动学模拟仿真,结果表明上下剪刃重叠量和刀弧水平偏移量的模拟结果均符合实际生产要求,从而更进一步证实了该新型的单液压缸驱动的液压滚切式板材剪切机构设计的合理性与运动学模型的正确性。
