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 f...
