Abstract

In order to improve the forming quality and production efficiency of superplastic forming Zn-5Al alloy drum winder

the super plastic forming process was analyzed.Based on principle of superplastic gas forming

basic principle of the parameters of superselective plastic forming process for aluminum alloy drum were presented according to the structure and technical features.Calculation method of the forming die design were given

and the key points of design and the use of die forming were described.The results show that tube blank by superplastic forming exhibits the features of precision shape with Ra≤6.3

which can be directly carried out polishing to meet the process requirements.Meanwhile

cost was reduced and the production cycle was shorten.
