摘要
对齿轮还半精锻模进行了失效分析，查明其主要失效机理是热疲劳。通过合理选材．使模具平均使用寿命提高约3倍。
The failure analysis of the gear-blank semi-precision forging die was made in this paper It is shownthat the main failure mechanism is thermal fatigue By reasonable selection of the die material, the service life of the die is prolonged by 500%
