基于Pro/E二次开发的大棒材减定径孔型系统

Secondary Development of Pro/E to the Roll Pass of Reducing and Sizing for Large Bars

应用切线孔型设计出大棒材减定径孔型系统,并利用Pro/E进行二次开发设计出参数化设计系统。还通过ANSYS有限元对三辊减定径孔型中的金属流动规律和等效应力、应变场进行分析。为大棒材减定径工艺的研究提供了一种新的方法和手段。

It is attempted to design the roll pass of reducing and sizing of large bars by using the tangent of the roll pass,and design the parametric system by using the secondary development of Pro/E.The metal flow pattern,equivalent stress and strain field analysis in the three-roll reducing and sizing groove were studied by the ANSYS finite element.A new method and means is provided for reducing and sizing of large bars.
