Influence of Guide Disc Postposition on Rolling Process of Accu-Roll Mill

With the aid of commercial FE code MSC.SuperForm, the rolling process of Accu-Roll mill is simulated and the influence of guide disc postposition on the value of outside diameter expansion of elongated shell, force parameters and twist deformation of the workpiece are analyzed in detail. Analysis results indicate that the value of outside diameter expansion of elongated shell, guide disc force and the axial force of mandrel decrease when the value of guide disc postposition increases, but separating force and twist deformation of the workpiece increase, which provides scientific guidance for designing Accu-Roll mill and setting adjustment parameters.
