Abstract
Способ моллирования листового стекла путем размещения плоской стеклозаготовки на форме, нагревания ее до температуры размягчения, изгибания под действием собственного веса и охлаждения, отличающийся тем, что, с целью повышения качества изделий по оптическим характеристикам за счет уменьшения площади контакта гнутой стеклозаготовки с формующей поверхностью формы, плоскую стеклозаготовку размещают на форме с кривизной формующей поверхности меньшей, чем заданная для издания, причем радиус кривизны формующей поверхности формы определяют по формулегде R- радиус кривизны формующей поверхности формы, мм;R - радиус кривизны поверхности изделия, мм;A - полухорда изделия, мм;h - расстояние между формующей поверхностью формы и поверхностью изделия по осевой линии, мм.The method of bending sheet glass by placing flat steklozavodov on the form, heating it to a softening temperature, bending under its own weight and cooling, characterized in that, in order to improve the quality of products according to optical characteristics by reducing the contact area of the bent steklozagrotovki with the forming surface of the form, planar steklozavodok placed on a form with a curvature of the forming surface is smaller than that specified for publication, and the radius of curvature of the forming surface of the form is determined form R is the radius of curvature of the forming surface of the mold, mm; R is the radius of curvature of the surface of the product, mm; A is the half-cord of the product, mm; h is the distance between the forming surface of the form and the surface of the product along the axial line, mm.
