钢管单芯棒圆周剪切法的实验研究

Experimental Study on Periphery Shearing for Steel Tube with Single Mandrel

介绍钢管圆周剪切的另一种方法──单芯棒圆周剪切法．通过运动学分析阐述了剪切金属的变形原理；实验研究证明了该方法的可行性并对切口断面质量进行了分析．

A new method of tube shearing, i.e.periphery shearing with single mandrel,was studied kinematically to reveal the mechanism of shearing deformation in metal.Experimental study proves the feasibilityof this method,with the fracture quality after shearing discussed.
