中文摘要: 通过对国内外现有的液压板材剪切机结构的原理分析,创新性地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SIMLINK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2000 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。
Abstract:This paper creatively put forward a new rolling shear mechanism which is driven by one horizontally positioned hydraulic cylinder by analyzing the present hydraulic shear mechanism at home and abroad. Moreover, based on the linkage, the simplify model of PR-11RⅢ-level composite rod linkage mechanism is obtained. Besides, in order to meet the demand of pure rolling, the kinematical analysis about the rolling shear mechanism is achieved by means of the building of closed loop vector method, then the kinematical simulation analysis is calculated with the help of the software of MATLAB/Simulink. Finally, depending on the development project on extensive popularization of 2000 mm rolling shear mechanism driven by one hydraulic cylinder for some large machine company, the simulation of the mechanism motion trajectory is conducted. The result of the simulation and the trajectory shows that the horizontal offset of the shear blade arc and the value of the overlap between the upper and lower shear blade are meet the design requirements, thus fully proves the reasonable of the rolling shear mechanism and the correctness of the kinematical analysis.
