中文摘要：

为找到不同剪切工艺条件下最大剪切力的分布规律,解决最大剪切力计算精度不高的问题,在确定两轴两偏心滚切剪上剪刃三个剪切动作和被剪轧件三个剪切阶段的基础上,根据剪切动作和剪切阶段的不同叠加关系,推导出滚切剪的三种剪切状态;通过理论分析和计算,揭示出三种剪切状态下剪切力的分布规律,给出了最大剪切力出现的位置;通过实际剪切实验,成功验证了三种剪切状态的真实存在,验证了三种剪切状态下剪切力的分布规律。研究表明,被剪轧件的宽度和轧件相对于上剪刃的摆放位置不同时,剪切力会呈现＂一个峰值＂、＂前低后高两个峰值＂和＂前高后低两个峰值＂三种分布规律,最大剪切力出现的位置有较大差异,这是最大剪切力计算的前提和基础条件。

英文摘要：

To find the maximum shear stress distribution under different shear conditions, and to solve the problem that maximum shear force calculation accuracy is not high, and determining that the two axes of two eccentric rolling shear thinning blade shearing action was cut three rolling cut on the basis of the three stages, depending on the relationship between the shearing action and superimposed shear stage, it deduced three rolling shear shearing state; theoretical analysis and calculations reveal state under three shear cut distribution of power, given the location of the maximum shear stress occurs; the actual shear test, successfully verifies the existence of the real state of the three shear and verifies the distribution of shear forces under three shear state. Studies have shown that the width is cut rolling and rolling on the cutting edge with respect that the placement is not the same, and the shear force will present ＂peak＂, ＇former low-high two peaks＂ and ＂high to low two peak ＂three distribution, and there are large differences arise position of the maximum shear stress, which i,s the premise and foundation conditions for maximum shear force calculations.
