中文摘要：分析了斗齿闭式模锻过程的工艺方案，采用有限元软件DEFORM-3D对成形过程进行了数值模拟。揭示了斗齿闭式模锻过程的金属流动规律和变形力学特征, 对斗齿闭式模锻过程的工艺和模具设计提供了指导。并用实验证明了该斗齿闭式模锻工艺的可行性。
英文摘要：The closed-die forging process for bucket tooth was analyzed. The forming process was simulated by software Deform-3D. The metal flow behaviors and deformation mechanics characteristics of the bucket tooth forging were presented,which provided structive significance for the process and the designs of die. The feasibility of the closed die forging process for bucket tooth is turned out by experiments.
