液压拉深是一种以流动液体作为传力介质的成形工艺。本文阐述了液压二次反拉深的变形机理 ,分析了液压二次反拉深试验过程中发生的各种破裂现象 ,找出了产生破裂的原因 ,提出了防止各种破裂现象产生的具体措施。
Hydraulic drawing is a forming process that uses a flowing liquid as the transmission medium. This paper expounds the deformation mechanism of hydraulic double deep drawing, analyzes various kinds of rupture phenomena during the hydraulic double deep drawing test, finds out the causes of rupture and puts forward the concrete measures to prevent various kinds of rupture .
