| 摘 要： | 基于斜轧扩管机特殊的空间结构,采用条件极值法确定轧辊辊面孔径点位置,解析出孔径点的空间坐标,据此建立斜轧扩管变形区的孔型开度计算模型.在此基础上求解出与轧辊孔型开度配套顶头的平整段锥角.结果表明,利用斜轧扩管机顶头平整段锥角计算方法获得的理论数值与实际生产工具参数相符合.

| Abstract: | Based on the special spatial structure of a rotary tube expanding mill,a conditional extremum method was used to determine the position of aperture points on the roller surface,to resolve the space coordinates of aperture points,and to construct a model for calculating the opening of holes in the formation zone of rotary tube expanding.The cone angle in the smoothing zone of plugs suitable for the opening of pass was calculated with the model.The calculation results are in agreement with the actual parameters of production. |
