摘要：

为提高同步器齿环的质量与生产效率, 采用现代数控雕刻与电火花加工相结合技术,对其精密锻造模具进行改进：凹模由整体改为镶嵌结构，冲头由分体改为整体，凹模由多个电极改为两个电极电火花加工，冲头由电火花加工改为雕刻加工，加工出的产品的质量与生产效率得到提高,为精密锻造技术在同步器齿环制造中的应用提供可靠的依据。

In order to improve the quality of synchronizer ring and production efficiency, using the modern combined technology of CNC engraving and EDM, the precision forging die was improved. The die structure was changed from the integrated type into inserted one. The punch was changed from splitting type into integrated type. A number of EDM electrodes were used instead of two electrodes. The punch was manufactured by the engraving process instead of EDM. The processed product quality and production efficiency were improved. This provides the reliable reference for the precision forging technology application in manufacturing the synchronizer ring.
