Study on Bladder Forming of the Shallow Basin-Shaped Aluminum Sheet Parts

Abstract:

The shallow basin-shaped aluminum sheet part had buckling defects after the bladder forming. Analysis the buckling defects’ mechanism, according to these, we proposed one step bladder forming process, used rolling leveler which could reduced the buckling height to level sheet before bladder forming, and made experiments to compare the structure effect of buckling height among the four kinds of die structure. The results showed that the one step bladder forming process is valid, and used the original die with sheet edge fold when it was bladder forming.
