摘要
分析了现有拉丝卷筒产生相对滑动的原因,认为是卷筒过度圆弧面导致圆周相对滑动,而圆周相对滑动是造成金属线材表面划伤、斑纹等缺陷的主要原因.设计了无圆周相对滑动的拉丝卷筒结构,取消了卷筒过度圆弧面,用推升滑轮实现卷筒上的线材上移.改进后的拉丝卷筒可以消除圆周相对滑动,减少了因相对滑动给线材表面带来的缺陷.
Analysis of the drawing reel demonstrates that the excessive arc surface produced circumference relative sliding, which is the main cause of surface defects of metal wire. Therefore, a drawing drum without circumference relative sliding was designed. The use of excessive arc surface was discontinued and the wire was driven up by means of the pulley. The improved structure can eliminate the circumference relative sliding, thus reducing the surface defects of the metal wire.
