摘　　要：弯管成形技术是一种常见的加工工艺,在弯管生产与变形理论方面仍有待加强研究。采用经典力学分析与生产试验相结合的方法,针对有芯弯管机的主要结构芯棒及弯曲模槽形状进行力学机理分析,同时根据工厂实际情况改变传统有芯弯管机主要结构设计形状,提出了独特的芯棒及弯曲模槽形状及相关力学计算方法,介绍了应用情况及结果,并总结了弯管所需力矩的计算公式。The elbow forming process was a popular mechanical forming technology. In this paper, a mandrel and shape of the bending mold, which are main structures of bender with a core, were analyzed simply and discussed. The traditional design shape was reformed. A unique shape and a simple calculation method were proposed, a brief introduction about application and results was given. The formula calculating bending moment required by elbow was summarized roughly.
