Combined with the characteristics of rubber track iron teeth forging, the iron teeth forging shape was simulated and the volume distribution curve of forging was analyzed using three-dimensional sculpt software.The precision blank shape was designed,and the free forging blank making process was replaced by cross wedge rolling precision blank making process. Using Deform-3D finite element method, the optimized blank was forged by simulation.The fill performance of mould, fluidity of metal and stress state of forging were obtained, which effectively enhanced the blank precision and the size stability, and improved efficiency as well as the extent of automation. The eligible forging was got by optimized blank using 630 cross wedge rolling equipment, and steady-going production of iron teeth forging was realized.
