Multi-layer cellular workpieces are used to manufacture fuel tanks, as well as the external hulls of aircraft. These designs are characterized by low weight and high strength. Monotonic formation with inert gases looks promising for the manufacturing of large workpieces. This article presents an approach to the modeling of energy-force parameters during free forming of titanium alloy workpieces in square dies with shortterm creep. The results of mathematical modeling of the investigated process are given in the form of inequations which allow estimating pressure and critical modes. According to these inequations, we found the influence of the process time on blank's relative thickness change in various points of its surface, as well as on its height and maximum damage rate change.
Реализация эффективности технологии изготовления квадратных коробчатых деталей может быть обеспечена внедрением новых технологических процессов деформирования. Рассмотрен способ совмещенной вытяжки с выдавливанием квадратных коробчатых деталей из квадратной заготовки, который позволяет достигнуть высоких экономических показателей. В работе представлено исследование течения материала, подобран вариант конструкции штамповой оснастки, которая дает возможность максимально повысить коэффициент использования материала и рационально построить технологический процесс штамповки.
