Pipe sinkingdrawing is analysed using continuous speed field and the equations of wall thickness variations in sinkingdrawing established.
利用连续速度场分析了圆管空拔过程,建立了空拔壁厚变化量计算式。

The effects of various amounts of deformation, steel grades, degrees of hardenability, die entry angle and drawing speeds on dia. sinkingdrawing are studied.
研究了不同变形量、钢种、硬化程度、模角和拔制速度对空拔管直径缩小量的影响。
