气门热精锻模在正常工作时其失效方式为磨损、冷热疲劳裂纹或压塌。然而由于模具加工、安装或使用不当会造成开裂 ,R位刮伤、毛坯卡模或平台麻坑等非正常失效。本文对各种失效形式及其对模具寿命与经济效益的影响进行了探讨
Valve hot precision forging die failure mode in normal work wear and tear, hot and cold fatigue cracks or collapse. However, due to mold processing, improper installation or use can cause cracking, R-bit scratches, blanking blank blank or platform pits and other non-normal failure. In this paper, various failure modes and their impact on mold life and economic benefits were discussed
