摘要
提出了一种新的、更趋精确合理的关于冷拉螺旋叶片坯料的展开与放样计算方法 ,并从实践中探索出叶片在展开与放样时其内径的精确修正系数k之值。
This paper gives a new and accurate and reasonable analyzing and spreading out method for the stuff of the cold drawing helical vane, and explores the precise adjusting coefficient in experiment for the inner hole of the helical vane.
