Abstrakt EN: The current production process of large aluminum bellows is often based on forming individual segments on a carousel followed by circumferential welding. This paper discusses the application of tube hydroforming technology for the forming of aluminum bellows. Comparing to more conventional manufacturing via forging, stamping and welding, tube or sheet hydroforming offers several advantages, such as decrease in workpiece cost, tool cost and product weight, fewer secondary operations, improvement of structural stability, and increase of the strength and stiffness of the formed parts, as well as more uniform thickness distribution. This paper also presents a simple experimental procedure utilizing a universal tensile-bending-drawing test as a suitable way for reliable material data fitting.
