摘　　要：分析了传统的圆坯料圆盘锯切机因夹紧装置引起的锯切质量、锯切效率以及锯切的安全性问题,在传统夹紧装置结构的基础上,研发了新型的圆坯料复合夹紧装置。该夹紧装置通过让刀机构将固定夹紧装置和浮动夹紧装置锁定在一起,形成一个整体,解决了夹紧过程中坯料中心线与锯片中心线的偏差问题,锯切完成后两侧锯切断面与锯片分离,不会划伤断面。该装置已成功应用于国内多家大型管棒材生产企业,实际使用效果良好。After analyzing the cutting quality, efficiency and safety problems on traditional round billet disc sawing machines caused by the clamping devices, the new-type round billet combined clamping device was developed based on the structure of traditional clamping devices. Locking the fixed and floated clamping devices to- gether to form a whole by cutter-relieving mechanism, the clamping device solved the centerline deviation problem between billet and saw blade. Sections at both sides are detached from saw blades after sawing, thus will not be scratched. The device has been successfully applied to multiple large domestic tube/bar producers with a good effect.
