Abstract
1. Способ термосилового формообразования металлических панелей, состоящих из листов и ребер жесткости или профилей, при котором сначала прилагают продольные усилия вдоль оси ребер жесткости до придания криволинейной формы панели вдоль этих ребер, а затем поперечные усилия с одновременным нагревом с вогнутой стороны панели участков в виде клиньев, расположенных поперек ребер жесткости, отличающийся тем, что ширину основания клиньев и шаг между участками выбирают обратно пропорциональным заданным радиусам кривизны, а глубину нагрева осуществляют на высоту ребер. ! 2. Способ по п.1, отличающийся тем, что поперечные усилия прикладывают с учетом последующей тепловой усадки нагретого металла и его пружинения, причем в местах с заданной двоякой кривизной поперечное усилие выбирают прямо пропорционально сумме заданных продольной и поперечной кривизны панели. 1. The method of thermopower forming of metal panels consisting of sheets and stiffeners or profiles, in which first apply longitudinal forces along the axis of the stiffeners until the panels are curved along these ribs, and then transverse forces with simultaneous heating from the concave side of the panel sections in the form wedges located across the stiffening ribs, characterized in that the width of the base of the wedges and the pitch between the sections are chosen inversely proportional to the specified radii of curvature, and the depth of heating is fected the height of the ribs. ! 2. The method according to claim 1, characterized in that the transverse forces are applied taking into account the subsequent thermal shrinkage of the heated metal and its springing, and in places with a given double curvature, the transverse force is chosen directly proportional to the sum of the specified longitudinal and transverse curvature of the panel.
