纤维切割过程中切断刀锋利性能分析

Analysis of the Sharpness Property of Chemical Fiber Cutter Blades

通过对短纤维切割工作原理的分析 ,建立了化纤生产中切断刀锋利性能变化的数学模型。分析结果表明 ,纤维切割过程中 ,切断刀锋利性能的变化主要与切断刀的初始刃口半径、刃口角度、刃口的磨损量以及刃口上缺口的深度有关。

Based on the analysis of the cutting principle of staple fibre, a mathematical model affecting the sharpness of cutter blades is established.The result shows that the cutter blade edge radius,edge angle,the linear abrasion and the edge notch depth are main factors affecting its sharpness.
