摘　　要：介绍了作者关于中频热推弯管新工艺的研究成果及根据该成果研制的弯管工艺参数CAD系统。中频热推弯管工艺是现有各种弯管工艺中最为经济有效的一种。它采用中频感应加热 ,在牛角芯棒上连续推制成形的方法加工弯管 ,避免了传统弯管工艺成形时弯管凸边管壁受拉减薄。A new process of steel elbow forming is introduced in this paper by means of pushing elbows on a core bar continuously with medium frequency induction heating. This process has eliminated the fault of traditional elbow forming technologies that the convex side of the formed elbows is stretched and thinned while the concave side pressed and thickened. A CAD system for the parameters of this process has also been developed. Industrial application indicates that this new technology is the most economical and effective among available elbow forming techniques.
