Abstract

Tube multi-point hydroforming is a new flexible forming technology for manufacturing of various tubular parts. In this process, tube may deform to different shapes via high pressure fluid only by one die. In conventional hydroforming, in order to produce any tubular part, it is necessary to manufacture a die which increasing time and cost. In present study tube multi-point hydroforming is studied using FE simulation and experiments. In this process a new die based on MULTI POINT FORMING was designed and manufactured. By using this die and due to good formability of brass 70/30, a bulged tube and a rectangular tabular cross section of brass 70-30 with initial thickness of 2mm are produced. The main difference of this die compared with conventional dies is the rigid surface is is substituted by wide spaced pins. By adjusting the pins height, different tubular cross sections could be produced. This process is simulated and verified experimentally and defects are predicted. In order to decrease these defects an elastic layer of polyurethane is used. For the bulged and rectangular cross section samples maximum decrease in thickness is 11% and 17% respectively and these results are matched with the experiment.
