Claims (2)

1. Способ формообразования листовых деталей двоякой кривизны, при котором формообразование осуществляют в несколько этапов и включающий установку листовой заготовки в универсальной матрице и последовательные локальные нажатия пуансоном с одновременным перемещением заготовки или пуансона относительно друг друга с заданным шагом, при котором происходит частичное перекрытие каждого предыдущего пятна приложения пуансона по поверхности заготовки, величина которого составляет не менее половины его диаметра, отличающийся тем, что формообразование осуществляют пуансоном, радиус сферы которого предварительно определяют с помощью расчетной конечно-элементной математической модели на базе системы ANSYS в зависимости от формируемого радиуса оболочки, а также от толщины и марки материала заготовки.1. A method of shaping sheet parts of double curvature, in which the shaping is carried out in several stages and includes installing the sheet stock in a universal matrix and sequential local pressing by the punch with the simultaneous movement of the workpiece or punch relative to each other with a given step, in which there is a partial overlap of each previous spot the application of the punch on the surface of the workpiece, the value of which is at least half its diameter, characterized in that brazovanie is carried out by a punch, the radius of the sphere of which is previously determined using the calculated finite element mathematical model based on the ANSYS system depending on the formed radius of the shell, as well as on the thickness and grade of the workpiece material. 2. Способ формообразования по п. 1, отличающийся тем, что для заготовок толщиною более 50 мм в район выреза универсальной матрицы устанавливают упорный цилиндрический стакан с радиусом сферической рабочей поверхности.2. The method of forming according to claim 1, characterized in that for workpieces with a thickness of more than 50 mm, a thrust cylindrical cup with a radius of a spherical working surface is installed in the cut-out region of the universal matrix.
