Method and device for annealing sheet glass

FIELD: chemistry. SUBSTANCE: invention relates to a method and a device for annealing sheet glass. A sheet of glass, heated to a temperature higher than the deformation temperature, is placed on a ring-shaped bending mould. The sheet of glass is lifted by a lifting element and separated from the bending mould. An area of glass, which contacts with the lifting element, is located at least 50 mm inside from the edge of the glass sheet. The area which is lifted is cooled to a temperature lower than the deformation temperature before the glass sheet reaches the deformation temperature, and after this glass sheet is lifted by the lifting element. EFFECT: reduction of an internal stretching tension, which arises on the glass edges. 16 cl, 2 tbl, 14 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 540 725 C2 (51) МПК C03B 25/02 (2006.01) C03B 23/023 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ 2012137239/03, 02.02.2011 (24) Дата начала отсчета срока действия патента: 02.02.2011 Приоритет(ы): (30) Конвенционный приоритет: (72) Автор(ы): ЯМАКАВА Хироси (JP), СУГАХАРА Акира (JP), КАТО Ясумаса (JP) 03.02.2010 JP 2010-022120 (43) Дата публикации заявки: 10.03.2014 Бюл. № 7 R U (73) Патентообладатель(и): АСАХИ ГЛАСС КОМПАНИ, ЛИМИТЕД (JP) (45) Опубликовано: 10.02.2015 Бюл. № 4 2122528 C1, 27.11.1998 .

Method and apparatus for precision forming of plastic materials such as glass to precise dimensions from sheet material

A process and apparatus for holding and forming a sheet of thermo-plastic material particularly optical or mirror grade glass to a precise dimension with contact only on one face thereof and capable of applying forming stress uniformly to the plastic body with a minimum of contact with the faces of the blank. The device which may be inserted into a tunnel oven or the like includes a female cavity conforming to the precise shape to which the thermo-plastic material is to be formed. The female cavity is positioned at an angle with respect to the vertical and includes an edge lip on the lower extremity against which a flat blank of material to be formed may rest over the cavity. A generally planar mold cover includes an edge hook which engages the opposite or upper edge of the blank. The entire assembly is inserted into an oven and the oven elevated to the softening temperature of the plastic blank. The edge force applied to the blank due to the weight of the mold cover causes the upper edge to move downward as the blank sags. The edge-only forming force is transmitted throughout the blank to bring its lower surface into precise engagement with the female mold below.
