Abstract：

For a certain 6XXX aluminum alloy automobile seat beam, the finite element model of hot forming process was established by forming simulation software Autoform, and the forming process and the part springback were analyzed and researched. Firstly, the springback analysis was performed by Autoform, and the part springback was compensated by the direct compensation method. After multiple iterations of compensation, the normal springback amount of part was controlled within ±0.5 mm, so that the part could meet the requirements of hot forming production. Then, the research and development of die and the trial production of part were carried out, and the deviation detection of trial production parts was conducted. The total deviation for each point of the parts was less than 0.6 mm, which met the quality requirements of the original equipment manufacture and proved the rationality and validity of the hot forming simulation. The results of simulation and trial production of parts show that the part processing based on the results of hot forming simulation and springback compensation can obtain high-quality products, which provides guidance for the mass production of automotive high-strength aluminum alloy parts.
