摘　　要：为了提高冲裁加工PE淋膜纸的断面质量,该文以冲裁速度、冲裁间隙、斜刃倾角三种工艺参数为影响因素,选择纸张毛刺高度作为评价指标,利用正交试验对工艺参数进行分析。结果表明:冲裁工艺参数对纸张毛刺高度的影响程度分别为:加工间隙>冲裁速度>斜刃倾角。冲裁速度的变化与纸张毛刺高度的变化呈负相关,斜刃倾角、加工间隙的变化与纸张毛刺高度的变化呈正相关。研究得出最优冲裁工艺参数组合为:冲裁速度为220 n·min^(-1),斜刃倾角为0.35°,加工间隙为20μm。该项实验研究结果对提高冲裁加工PE淋膜纸的断面质量和生产效率以及降低产品的加工成本具有重要参考价值,在实际生产中具有一定的实用性、经济性价值。In order to improve the section quality of PE coated paper in punching process,three process parameters,including punching speed,punching gap,and beveled edge inclination,are selected as influencing factors,and paper burr height is selected as the evaluation index,the process parameters are analyzed by orthogonal test.The result shows that the influence of the blanking process parameters on the paper burr height is as follows:punching gap>punching speed>beveled edge inclination.The change of punching speed is negatively correlated with the change of paper burr height;while the change of beveled edge inclination and the punching gap is positively correlated with the change of the paper burr height.The research concludes that the optimal blanking process parameter combination is:punching speed is 220 n·min^(-1),beveled edge inclination is 0.35°,machining gap is 20μm.The results of this experimental study have important reference value for improving the section quality and production efficiency of PE film paper,reducing the processing cost of products,and have certain practical and economic value in the actual production.
