摘要：

铜合金室温锻造过程中存在着模具寿命普遍较低的情况，通常只有200~500件，有些模具甚至在试模过程中会产生严重的开裂现象。对铜合金室温开式模锻的模具强化技术及主要工艺难点进行了系统的论述，在目前的实际生产中往往利用有限元技术可以直观地分析成形过程的特点，对铜合金室温开式模锻模具和工艺进行针对性的改进。在生产过程中根据本文的模具设计和工艺进行改进的模具，其寿命普遍可以超过3000件，甚至有的模具寿命可以超过60000件，模具寿命提高了数十倍。

The issue on short life of forging mould in the forging process of copper alloy at room temperature, usually occurs after only 200-500 workpieces being produced, and some moulds are badly cracked. Therefore, the strengthening technology of forging mould and major technological difficulties on the copper alloy open-type forging mould at room temperature were discussed systematically. In the actual production, the characteristics in the forming process were analyzed by finite element technology directly, and the forging mould and process were improved. The results show that based on the improved forging mould and optimized process, the forging mould can produce more than 3000 workpieces, and some forging moulds can produce up to 60000 workpieces. Thus, their life was prolonged dozens of times than before.
