Abstract: Aimed at the focus tasks in plastic deforming theory and modeling of die cavity for exact special-shaped product extrusion, in virtue of the theories in conformal mapping of Complex function and metal plastic deforming, three-dimension plastic stream of matal special-shaped product extrusion is transformed into two-dimension axis-symmetry model. Hence, the mathematical models of stream function, velocity field and strain rate field etc are obtained for metal plastic stream, and universal three-dimension analysis method for metal special-shaped extrusion is established as well. Meanwhile, by utilizing the principle of energy extreme value, above theoretical tasks for special-shaped product extrusion deformation and optimized engineering modeling of die cavity get solved.
