对线材在无滑动拉丝机卷筒上的爬升情况和受力情况进行了分析，提出了线材在卷筒上的爬升条件、无切向滑动的限定条件及沿轴向推移的自锁条件，并由此得出卷筒斜角α的最佳选定范围值及计算公式。
The paper analyzes the climbing condition and force of the wire on the non-slip wire drawing machine, puts forward the condition of the wire climbing on the reel, the condition of no tangential sliding and the self-locking condition in the axial direction The optimal selected range value and calculation formula of the bevel angle α of the drum are obtained.
