Abstract
1. Способ моллирования листового стекла, включающий размещение заготовки в нагретой печи в разогретой форме, нагревание и изгибание, отличающийся тем, что перед изгибанием заготовки печь нагревают на 140-160°С выше температуры размягчения стекла.2. Форма для моллирования листового стекла, содержащая формующую поверхность с заданной кривизной, отличающаяся тем, что в двух диаметрально расположенных секторах формующей поверхности в нижней части формы в области контактирования гнутой заготовки стекла с формующей поверхностью выполнены углубления в виде тел вращения с треугольным сечением с шириной рабочих граней 5-10 мм.1. A method of molding sheet glass, including placing the preform in a heated furnace in a preheated form, heating and bending, characterized in that before bending the preform, the furnace is heated 140-160 ° C above the glass softening temperature. A mold for molding sheet glass containing a forming surface with a given curvature, characterized in that in two diametrically located sectors of the forming surface in the lower part of the mold in the contact area of the bent glass workpiece with the forming surface, recesses are made in the form of bodies of revolution with a triangular section with a width of working faces 5-10 mm.
