论并条机牵伸机构中压力棒形式与优化设计

A Discussion about the Form of Press Bar of Drawing mechanism in Drawing Frame and Its Better Project

为了提高纺纱质量,对现代高性能并条机压力棒牵伸的机理、压力棒的工艺条件和形式及其与纺纱质量的关系进行了理论概括和分析。指出了压力棒的截面形状、曲率半径、抗弯厚度等是决定牵伸工艺性能的重要因素,并提出防纱疵压力棒优化设计的6项措施。

In order to increase the spinning quality, this paper gives analysis and conclusions about the mechanism of press bar drawing in modern high property drawing frame, its technical requirements and shape, and their relations with spinning quality. It points out the cross section ,curvature radius and bending resistance of press bar are very important factors affecting drawing mechanism. This paper also offers us six measures for better project of press bar with nibs resistance.
