Abstract
Tube parts formed by hydroforming technology have many outstanding advantages, such as high mechanical properties, fast forming time, and the ability to shape complex parts. U-shaped tube parts with branches are applied in various fields, such as the automotive, electronics, and medical industries. The current challenges in hydroforming technology for manufacturing these parts lie in controlling and determining suitable process parameters to ensure the highest product quality. Through numerical simulations and theoretical calculations, with the input material being a copper tube made from CDA110, this study has investigated the parameters of die cavity fluid pressure and punch displacement. Based on these results, a regression equation for the relationship between fluid pressure and punch displacement was established, which allows for determining the appropriate ranges for fluid pressure and punch displacement to successfully hydroform U-shaped parts with branches. The research results aim to assist engineers in reducing the time required to identify suitable process parameters for hydroforming similar-shaped parts.
