A new die design for the hydroforming of stepped tubes
Source abstract
Abstract
Tubular components, such as stepped tubes, conical tubes and box shape tubes, are mainly produced in tube hydroforming process. Obtaining a sharp corner is a main goal in some of these components. In this paper, the corner filling in stepped tubes is studied by a multistage new die. The proposed die was simulated and the filling of die cavity was investigated. In this respect, the finite element software, ABAQUS 6.4, has been used for simulation. In order to verify the simulation results, the new die of stepped tube was manufactured and some experiments have been performed. The results obtained from the experiments verified the simulation results. It is shown that by using the new die parts with sharp corners could be produced. The simplicity of the die and low internal pressure are another advantages of this die. The thickness distribution was also examined by both the FE simulation and experiments and it is shown that a better distribution could be obtained by the proposed die set.
