摘要：

通过对液压支柱柱头零件的成形工艺分析，提出了有别于传统圆钢车削工艺的复合模锻工艺方案，并采用数值模拟方法研究了两种复合模锻工艺的工艺过程和成形载荷。综合对比结果表明：与传统切削工艺相比，复合模锻工艺在材料利用率以及制件质量上有明显优势；不对称复合模锻效果更优，但所需设备载荷略大；在上动压机条件下，上冲头要比下冲头更容易冲入坯料；该工艺也得到了后续工程实践的证实。

Through the analysis of hydropost chapiter forming process, the compound die forging process scheme was proposed, which is different from the traditional round steel turning process. The forming procedure and load of two compound die forging processes were analyzed by numerical simulation method. The comprehension conparison results show that compared to the traditional tuming process，the compound die forging process has obvious advantages in material utilization ratio and product quality； the asymmetric compound die forging process is better，except for a higher equipment load is needed；punching into the blank under the condition of upper action press is easier for upper punch than the lower one and the process is also confirmed by the subsequent engineering practice.
