摘要：

为加快生产速度，并节约人工、材料和时间成本，以一种汽车变速箱花键轴为研究对象，尝试将加工工艺改为多工位锻造，并联合Deform-3D软件进行同步研究。根据零件外形特征和加工材料的极限变形程度初步设计了两种理论上比较可靠的多工位自动锻造成形工艺，通过搭建符合实际条件的虚拟锻造试验平台完成了两种工艺的成形模拟，并根据成形结果进行了工艺评定，分析和对比了等效应力、载荷变化规律等试验结果。结果表明：设计的两种多工位锻造工艺基本可行，并且工艺1在零件成形质量和模具寿命方面表现更好。最后，参考工艺结果通过工业试验完成了变速箱花键轴的制造，锻造速度快，生产稳定，并且零件生产质量较好，无裂纹等缺陷，验证了多工位锻造工艺方法的有效性。

In order to speed up the production speed and save the cost of labor, material and time, for a kind of automotive transmission spline shaft, the process was changed to multi-station forging, and the synchronous research was conducted with the help of Deform-3D. Then, according to the shape characteristics of parts and the limit deformation degree of processed material, two theoretically reliable multi-station automatic forging processes were designed preliminarily, and the forming simulation of the two processes was completed by building a virtual forging experiment platform that met the actual conditions. Furthermore, according to the forming results, the process was evaluated, and the experimental results of equivalent stress and load change law were analyzed and compared. The results show that the two multi-station forging processes are basically feasible, and the process 1 performs better in the forming quality of part and the mold life. Finally, the manufacturing of transmission spline shaft is completed by reference to the process results through industrial experiments. The forging speed is fast, the production is stable, and the quality of part is good without cracks and other defects, which verifies the effectiveness of the multi-station forging process method.
