Aiming at the important part of the numerical simulation technology of metal plastic forming process, the finite element mesh re-division technology is deeply studied. A fully automated 4-node quadrilateral mesh generation method is proposed. A series of algorithms and technical processing methods in the re-segmentation technology are analyzed in detail. The re-division technique is applied to the numerical simulation of the die forging process.
