內螺旋凸筋管的內模溝槽曲線理論解
Theoretical Solution of Groove Curve on Plug of Rifled Tubes
-
摘要: 通過理論分析,建立了拔制內凸筋管的內模溝槽曲線.經過工廠試用,獲得了按國際標準交貨的產品,包括幾何尺寸精度和力學性能.Abstract: The key technology for producing rifled tubes is designing the shape of plug.It is diffcult to produce high quality rifled tubes by using of the straight line instead of the plug curve.Through analysis of theory,a theoretical formula is set up and achieve satisfied result through factory try out.
