Researches regarding the hydroforming process of aluminum components

Abstract

The lightweighting with aluminum offers the potential for using unconventional fabrication technologies such as sheet hydroforming. Triform process is an unconventional sheet forming technology where the blank sheet is placed under a flexible rubber pad and is deformed under the action of the hydraulic pressure applied from the top of the equipment. The part shape is given by the shape of the die located at the bottom of the equipment. In the paper are presented the experimental results, regarding the influence of the fluid pressure towards the parts properties. The parts quality is evaluated in terms of springback variation. The results could lead to the implementation of the designed procedure for triform die and equipment..
