摘要
本文通过对某航空发动机典型阶梯圆筒薄壁钣金件的拉深成型过程进行工艺方法设计,该类零件通常有较大的深径比,加工过程材料流动较困难,易出现应力集中导致出现开裂、起皱等现象,为改善该类零件工艺方案,提升产品合格率,本文通过理论计算和成型工艺分析,结合仿真分析、实践验证等方法,为该类零件设计出切实可行的加工工艺方案,解决成型过程中的开裂等问题,并为该类零件如何进行工艺方案设计提供理论参考。
In this paper,the deep drawing process of a typical stepped cylinder thin-walled sheet metal part of an aero-engine is designed.This kind of part usually has a large depth-to-diameter ratio.The material flow in the pro⁃cess is difficult,and the stress concentration is easy to cause cracking and wrinkling.In order to improve the pro⁃cess scheme of this kind of part and improve the qualified rate of the product,this paper designs a feasible process⁃ing scheme for this kind of part through theoretical calculation and forming process analysis,combined with simula⁃tion analysis,practical verification and other methods.Solve the problem of cracking in the forming process,and provide a theoretical reference for how to design the process scheme of this kind of part.
