摘要：

针对汽车传动轴重要零部件——端面齿突缘叉，分析了其在锻造生产过程中存在的飞边大、材料利用率低、产品成本高等问题和不足，提出一种改进后的端面齿突缘叉的锻造工艺。改进后的锻造工艺采用Deform-3D软件模拟端面突缘叉的锻造过程；针对突缘叉的锻造模具结构，采用组合式制坯模结构，下模不固定，方便更换；预锻叉朝上，并设计定位台阶，从而保证了坯料与型腔位置的对称性；采用可调节式限位块结构，保证了模具与限位块高度相匹配。采用改进后锻造工艺进行产品试制，结果表明，生产出的端面齿突缘叉锻件不仅可以满足力学性能要求，而且材料利用率提高到90%以上，生产效率提高10%~15%。

For an important part on the automobile drive shaft such as the face tooth flange fork, the problems of large flash, low utilization rate of material and high product cost etc. in the forging process were analyzed, an improved forging process of the face tooth flange fork was put forward, and its forging process was simulated by software Deform-3D. Furthermore, a combined mould structure was designed, and the lower mould was not fixed so as to replace conveniently. Then, the pre-forging fork was put upward, and the positioning step was designed to ensure the symmetry of the cavity and the blank position. Furthermore, the symmetry between the mold and the height of stopper was ensured by adjusting limit block. The practice production shows that the face tooth flange fork manufactured by the improved forging process can meet the mechanical property requirements, the material utilization rate increases to more than 90%, and the production efficiency is increased by 10%-15%.
