摘　　要：分析了高频焊管生产线飞锯锯片失效的主要形式及原因,提出延长飞锯锯片使用寿命的方法.分析认为:通过合理设置锯切参数,切割时避开不规则成型处,合理选择齿型,根据钢管壁厚选择齿距,增强冷却效果和及时调整飞锯夹紧块同心度,可防止锯片崩齿、瓢曲和糊齿,大幅提高锯片的使用寿命.Analyzed in the article are the main failure types and the causes of the flying saw blade.Accordingly method for extending the service life of the said blade is proposed.It is regarded via the analysis that the blade service life shall be tremendously extended by means of such actions as properly setting the sawing parameters,avoiding irregular forming location when cutting,selecting proper tooth shape,slecting proper tooth pitch as per pipe wall thickness,enhancing the cooling effectiveness as well timely adjusting the clamping block concentricity of the flying saw,which can preventing collapse,buckling and pasting of the blade teeth.
