Abstract：

Basic on the analysis of cross-axle,a radial extrusion force calculation method was proposed.Through the analysis of a quarter of forgings,the total pressure of floating die closing extrusion was similarly counted as the sum of single axle proximate force of extrusion,friction force of work piece and bottom die and closing-die force of the floating die.After comparing the results with Deform-3D numerical simulation,the method was verified through forgings with two or three shaft and it was proved cientific.On the basis of the comparison,an amendment was further proposed aim at this method and error was reduced.
