摘要
通过对典型壳体件工艺分析、产品图与锻件图转换、模具设计原则以及生产过程的阐述,研究了影响壳体件热模锻模具开裂失效的几个因素。壳体件模锻应避免出现变形死区以及出现闭式锻造,工艺上应解决坯料中心与模具中心定位问题,锻件设计上注意连皮设计对成形力的影响。分析结果对今后壳体件热模锻工艺制定、锻件设计以及模具结构设计具有十分重要的借鉴意义。
Effects on the hot forging mould cracking of typical shell were studied through analyzing the process of the typical shell,switching between product drawing and forging drawing and the description of design principles and manufacturing process.In order to avoid closed-die forging and deformstion dead areas of the shell,the problem of center location between the blank center and the die center should be solved and the effect of the flash design on the forming force should be cared during the forging design.It provides a significant reference for hot forging mould process design,forging design and die structure design of titanium alloys shell.
