剪板机刀片剪切模型的建立与分析

Establishment and Analysis of Mechanical Modle for the Blade of Plate Shearing Machine

为了研究剪板机刀片磨损问题,建立了刀片运动时的剪切模型。模型以波动力学为基础,给出了其性能评价指标,并从满足剪板机剪切要求与理想状态两方面分析了剪板机刀片的剪切模型,得到了两种情况下的相关方程,计算出了刀片磨损的影响因素及其之间的关系。为刀片的力学分析提供了数学基础,为刀片及剪板机参数的制定提供了参考。

Aiming at the problem of wear in the blade of plate shearing machine, a blade＇s shearing model is developed which based on the theory of wave mechanics. The performance evaluation index of blade＇s shearing model is also presented. The correlation equations meeting the demand of blade＇s shearing and ideal state are obtained through the analyses of the blade＇ s mechanical model on both cases. The influencing factors and their relationship of wear failure in the blade of plate shearing machine are calculated. It lays the mathematical foundation for the analysis calculation on the blade and provides references for design of blade and plate shearing machine.
