| 摘 要： | 建立了包括板料、凸凹模和压边圈在内的整体分析模型，对锥形件拉深成形过程进行了数值模拟。还将分析结果同实验数据进行比较，揭示了锥形件成形的机理。根据多组工艺参数的对比和分析，得出了板料破裂和起皱的原因，这对于拉深过程的智能控制具有重要的意义。

| Abstract: | In this paper,the whole analysis model including sheet metal,dies and blank holder is built.And the numerical simulation is carried out to conical parts' drawing process.Compared with experimental results,the mechanism of conical parts' deep drawing is presented.Furthermore multi group process parameters,which will affect on the forming ability,have been applied to drawing process.Then the critical conditions and reasons for side wall wrinkle and fracture are provided. The research is also of great significance for realizing intelligent control forming process. |
