Research on High Speed Superplastic Torming Technology of Aluminum Alloy Automotive Panel
High speed superplastic forming is a new technology,which combines hot stamping and superplastic gas bulging.It uses the high speed of hot stamping and good formability of superplasticity to solve the difficulties of forming aluminum alloy in stamping and low speed of superplasticity.On the basis of research of the properties of 5083 aluminum alloy,the forming of a car engine cover was experimented by using this technology.The results show that this technology is feasible and the production efficiency is high.
