Description
к форме подают ультразвук частотой 15 кГц, в результате чего форма начинает колебатьс в вертикальной плоскости, это уменьшает трение разм гченного стекла о форму и предотвращает прилипание стекла к металлу . Стекл нную заготовку выдерживают в печи моллировани до получени нужной конфигурации. По окончании процесса молли .ровани печь отключают дл отжига стекла. При охлаждении стекла до 500°С подача ультразвука ирекращаетс .An ultrasound frequency of 15 kHz is applied to the mold, as a result of which the shape begins to oscillate in a vertical plane, this reduces the friction of the softened glass onto the shape and prevents the glass from sticking to the metal. The glass blank is held in a bending oven until the desired configuration is obtained. At the end of the molly process, the furnace is turned off to anneal the glass. When the glass is cooled to 500 ° C, the ultrasound feed is discontinued.
Использование предлагаемого способа моллировани стекла обеспечивает по сравнению с существующнм способом следующие преимущества:The use of the proposed method of glass bending provides the following advantages as compared with the existing method:
достижение точной конфигурации;achieving accurate configuration;
Предотвращение образовани поверхностных дефектов стекла, что значительно повышает качество изделий;Preventing the formation of surface defects in glass, which significantly improves the quality of products;
увеличение выхода продукции.increase output.
Предлагаемый способ с наибольщим эффектом может быть использован три .производстве малогабаритных изделий, например сферических зеркал. The proposed method with the greatest effect can be used for the production of three small-sized products, such as spherical mirrors.
