The stress field of the combined extra height forging die, which was reformed from solid extra height forging die, was calculated and analysed using finite element method (FEM). The major factors influencing the stress field of forging die and its variation law were discussed. The results demonstrated that the combined forging die could meet the working strength demand, and that the calculated results by FEM were superior to that by the general design method for die strength. The conclusion could provide evidence for improving the forging die structure and durability.
