基于Matlab的PSW轧辊棍形设计

Roll-shape design of PSW based on Matlab

三棍行星轧机(PSW)因其高效、节能、环保且可实现轧件无旋转轧制,而成为棒材、线材和管材连轧生产线粗轧道次最佳设备。建立轧件不转动轧制轧辊曲面的数学模型,设计考虑轧制切向滑移的轧辊棍形计算流程。利用Matlab人工智能语言二次开发出轧辊棍形计算程序,运算得到了轧辊棍形数据。在Pro/E中建立轧制三维装配模型,证实了轧辊棍形几何形状的合理性。通过轧机轧制调试试验,验证所设计的轧辊棍形满足轧件不转动条件。

3-Roller PSW become the best rough rolling equipment of rod,wire and tube rolling production line,because of its high efficiency,energy saving,environmental protection and its ability of rolling without spin.Mathematical model of the roller surface which meets nonrotating condition of the workpiece was established,and roll-shape calculation process was designed under the condition of considering rolling tangential slip. Rollshape calculation program was developed using the secondary development function of Matlab artificial intelligence language,and roll-shape data were obtained by running the program.3-D assemble model of rolling was established in Pro/E software,which confirmed the rationality of the rolller geometrical shape. Through rolling debugging test of the rolling mill,it verifies that the design of roll- shaped meets nonrotating condition of the workpiece.
