基于冷挤压模具的FMEA研究

The Study of FMEA Based on the Clod Hobbing Mould & Die

冷挤压模具在设计与生产制造过程中存在着多种失效形式,而每种失效形式都和潜在的不合理设计、制造以及装配有关。本文对此提出了在模具设计图样完成之前和工艺规划之前进行失效模式及后果分析(FMEA)活动,并对如何建立FMEA进行了详细的论述,最后给出了应用实例。

Many failure modes of the clod hobbing die are relative to the potential wrong design, wrong manufacturing and wrong fit of the mould. That FMEA （ Failure Mode Effects Analysis） should be done before the design of the mould and the plan of the process was presented, how to establish the FMEA was discussed and the example was put forward.
