Abstract
1. Способ моллирования стекла преимущественно для авиационного остекленения путем размещения плоской стеклозаготовки на рамочной форме, нагревания ее до температуры размягчения стекла, изгибания под действием собственной массы до кривизны поверхности, заданной для изделия, и последующего охлаждения, отличающееся тем, что, с целью повышения качества изделий по оптическим характеристикам за счет уменьшения площади контакта гнутой стеклозаготовки с формующей поверхностью формы, охлаждение начинают в момент, когда расстояние между формующей поверхностью формы и поверхностью гнутой стеклозаготовки по вертикали от линии сопряжения полурам находится в пределах 5-12 мм.2. Форма для моллирования листового стекла преимущественно для авиационного остекления, содержащая составную раму, отличающаяся тем, что, с целью повышения качества изделий по оптическим характеристикам за счет уменьшения площади контакта гнутой стеклозаготовки с формующей поверхностью формы, рама составлена из двух симметричных полурам, выполненных вырезом центрального сегмента рамы, имеющей формующую поверхность с кривизной, заданной для изделия, по двум вертикальным плоскостям срезов, равноудаленным от осевой линии рамы, причем полурамы сопряжены по плоскостям срезов, а ширину выреза определяют по формулегде b - ширина выреза центрального сегмента рамы с формующей поверхностью, имеющей кривизну, заданную для изделия, мм;R - радиус кривизны изделия и рамы, мм;A - полухорда гнутой стеклозаготовки, мм;h - расстояние между формующей поверхностью формы и поверхностью гнутой стеклозаготовки по вертикали от линии сопряжения полурам, мм.1. The method of glass bending mainly for aircraft glazing by placing flat steklozavodok on the frame form, heating it to the glass softening temperature, bending under its own weight to the curvature of the surface specified for the product, and subsequent cooling, characterized in that products according to optical characteristics by reducing the contact area of the bent steklozavodok with the forming surface of the form, cooling begins at the moment when the distance between the forms guide surface shape and surface steklozagotovki bent vertically from the line interfacing half-frames is within 5-12 mm.2. Form for bending sheet glass mainly for aviation glazing, containing a composite frame, characterized in that, in order to improve the quality of products according to optical characteristics by reducing the contact area of bent steklozavtotovka with the forming surface of the form, the frame is composed of two symmetric half-frames cut by the central segment a frame having a forming surface with a curvature defined for the product, along two vertical planes of sections, equidistant from the centerline of the frame, with the floor the frames are conjugated along the cut planes, and the cutout width is determined by formulah where b is the cutout width of the central segment of the frame with the forming surface having the curvature specified for the item, mm; R is the curvature radius of the item and frame, mm; h is the distance between the forming surface of the mold and the surface of the bent steklozagotovokovki from the line of pairing half-frames, mm.
