이와 같은 제조공정으로 성형하는 본 발명의 유리그릇 제조방법은 폐유리나 성형유리를 절단 연마하여 얻어진 판유리(1)의 바닥밑면에 전사지(2)를 부착시키고 이를 접시형의 성형틀(3) 주연테(3-1)에 개재되어진 다수개의 치구(4)를 이용하여 안치하여 주되 성형틀(3)에는 반단열 및 윤활작용을 하는 도형제(Cu 및 Se합금)(5)를 스프레이나 브러싱으로 도층하고 도층된 성형틀 내면에는 석면(6)을 구비시킨 상태에서 이형물질로 미립자의 알루미늄 옥사이드 분말(7)을 적당량 깔고 주연테(3-1)에 개재되는 치구(4)의 판유리 접촉부에는 석필가루(8)를 칠하여준 성형틀의 치구에 판유리를 적재한 상태에서 1차 예열로 (a)에서 약 300-400℃로 예열하고 2차 가열로에서 약 650-750℃로 가열시켜 판유리를 유리그릇 형태로 굴곡 형성시킨 다음 3차로 (c)에서 약 600℃로 온도를 내려주고 이송 즉시 에어(a)로 급냉시켜 강화유리로 하여준 다음 부로와(9)에서 약 30℃까지 서행하여 완성된 유리그릇완제품(A)을 얻도록 한 것이다.In the glass bowl manufacturing method of the present invention, which is formed by such a manufacturing process, the transfer paper 2 is attached to the bottom surface of the plate glass 1 obtained by cutting and polishing waste glass or molded glass, which is then formed into a plate-shaped mold 3. A plurality of jig (4) interposed in (3-1) is settled, but the mold 3 is coated with a coating (Cu and Se alloy) (5), which is semi-insulated and lubricating, by spraying or brushing On the inner surface of the formed mold, asbestos (6) is placed on the plate glass contact portion of the jig (4) interposed in the periphery frame (3-1) with an appropriate amount of fine particles of aluminum oxide powder (7) as a release material. (8) With the plate glass loaded on the mold of the forming mold, preheat it to about 300-400 ℃ in the first preheating furnace (a) and heat it to about 650-750 ℃ in the secondary heating furnace. Bent into a shape and then at a temperature of about 600 ° C. in the third lane (c) Is one to obtain the dropping immediately transfer the air (a) by quenching the glass to enhance the standard in the following part with (9), complete with slow to about 30 ℃ glass bowl finished product (A).

본 발명은 유리그릇(A) 완제품을 성형제조함에 있어 유리그릇의 형상을 성형함과 동시에 유리그릇에 전사도 동시에 입혀지도록 하여 유리그릇 제조공정을 단축하여 생산원가의 절감을 기할 수 있게 한 것이다. 현재까지 일반적으로 전사지가 부착된 유리그릇의 성형방법은 대개가 먼저 유리그릇만을 원하는 형상으로 제조하여 주고 그 밑면이나 바깥면에 전사지를 부착시킨 다음 재차 가열로에서 전사지를 용착시켜 주어야하므로 가열공정이 두 번 중복되어지는 문제점이 있을뿐만 아니라 전사지 용착면에 고르지 못할 경우에는 소망스런 무늬모양을 얻지 못하는등의 결점이 있었다.The present invention is to reduce the production cost by shortening the glass bowl manufacturing process by molding the shape of the glass bowl and the transfer of the glass bowl at the same time in molding the finished product of the glass bowl (A). In general, the method of forming a glass bowl with a transfer paper generally requires that the glass bowl is first manufactured in a desired shape, the transfer paper is attached to the bottom or the outer surface thereof, and the transfer paper is welded again in a heating furnace. In addition to the problem of overlapping twice, if the transfer paper welding surface is uneven, there was a defect such as not obtaining the desired pattern.

본 발명에서는 이와 같은 종래의 제조공정의 문제점을 해결하기 위하여 유리그릇의 형태로 절단된 판유리에 직접 전사지를 부착시켜 직접 가열로에서 유리그릇의 형태 성형중에 전사지가 피착되어지도록 하였으므로 그릇의 형상에 관계없이 먼저 전사지가 피착되어진 상태에서 유리그릇의 형태로 성형되어지는 단일 공정으로 전사지의 피착과 유리그릇의 굴곡면이 동시에 성형되어져 전사지의 피착상태의 양호하고 소망하는 형태의 유리그릇을 얻게 되는 것이다.In the present invention, in order to solve the problems of the conventional manufacturing process, the transfer paper is directly attached to the plate glass cut in the shape of the glass bowl so that the transfer paper is deposited during the shape of the glass bowl in the direct heating furnace. Without the transfer paper is first deposited in the form of a glass bowl in the form of a single process of the transfer paper deposition and the glass bowl is formed at the same time to obtain a good and desired glass bowl of the transfer paper deposition state.

이와 같은 본 발명의 제조방법은 임의의 형태를 갖는 성형틀에 도형제로 반단열이며 윤활작용을 하는 도형물질을 스프레이하여주고 석면을 개재시킨 상태에서 성형유리그릇에 부착되지 않는 이형물질인 알루미늄옥사이드 분말 적당량을 성형틀 내면에 살포시킨 상태에서 판유리를 안치시켜 약 650-750℃의 온도로 2차 가열로 (b)에서 가열시키게 되면 판유리가 안치된 치구의 접촉면에 도착되어 있는 석필가루가 판유리와 치구의 접촉을 매끄럽게 하여 가열로 인하여 판유리가 변형 굴곡되어질 때 부드럽게 형상변형되어지게 하였으며 변형된 판유리의 바닥면이 접하는 석면위에는 이형물질인 미립자의 알루미늄 옥사이드 분말이 뿌려져 있어 변형된 판유리가 분말에 올려져도 냉각된 상태에서는 쉽게 분리되어 유리그릇의 바닥면을 고른상태로 유지시킬 수 있도록 되어 있으며, 성형틀의 바닥내면에 개재되어지는 석면은 일정두께를 유지하도록 하여 주므로서 가열로의 고열이 스텐레스로된 성형틀을 통하여 직접적으로 성형유리 그릇에 접하여지는 것을 방지하여 주고 또한 2차 가열로의 높은 열로 판유리가 유리그릇 형태로 변형되며 성형되어질 때 유리그릇의 바닥밑면을 형성하게 되는 성형틀 내면에 일정두께의 석면층을 개재하였으므로 성형되는 유리그릇의 바닥면이 옴폭하게 들어간 형태를 유지시켜 유리그릇 사용시 안정감을 줄 수 있도록 하였으며, 3차로를 지난 즉시 공급되는 에어는 그릇내면으로 강하가 분사되어 유리그릇을 약 300℃로 급냉시키므로 강화유리가 되도록 하여 유리그릇의 강도를 높혀주게 되는 것이다.Such a manufacturing method of the present invention is an aluminum oxide powder that is a release material that does not adhere to a molded glass bowl in a state of spraying a shape material that is semi-insulated and lubricating with a mold in a mold having an arbitrary shape and interposing asbestos. When the appropriate amount is sprayed on the inner surface of the mold, the plate glass is placed and heated in the secondary heating furnace (b) at a temperature of about 650-750 ° C. Smooth contact of the plate causes the plate glass to be deformed smoothly when it is deformed and bent due to heating.Also, the aluminum oxide powder of fine particles, which is a release material, is sprayed on the asbestos contacting the bottom surface of the deformed plate glass so that the plate glass is cooled even if it is placed on the powder. When the glass bowl is separated easily, keep the bottom of the glass bowl even. Asbestos interposed on the bottom inner surface of the molding mold maintains a constant thickness, thereby preventing the high temperature of the heating furnace from directly contacting the molded glass bowl through the stainless steel molding mold. The plate glass is transformed into a glass bowl by the high heat of the secondary heating furnace, and when the molded glass is formed, it has an asbestos layer with a certain thickness on the inner surface of the mold, which forms the bottom surface of the glass bowl. It maintains its shape to give a sense of stability when using glass bowls, and the air supplied immediately after the third lane drops into the inner surface of the vessel and rapidly cools the glass bowls to about 300 ℃, thus increasing the strength of the glass bowls. Will be given.

특히, 본 발명에서 사용되는 성형틀은 그 재질을 스텐레스 스틸로 하여 가열과 급냉시 온도변화에 따른 스케링이 생기는 것을 방지하기 위함이고 성형틀은 주물로 이용할 수도 있는 것이다. 그리고, 이형물질로 사용되는 알루미늄 옥사이드 분말은 용융온도가 약 2000℃이상이므로 가열로를 통과시에는 용융되지 않아 수차의 반복사용이 가능한 것이다.In particular, the molding die used in the present invention is made of stainless steel to prevent the occurrence of scaling due to temperature changes during heating and quenching, and the molding die may be used as a casting. In addition, since the aluminum oxide powder used as the release material has a melting temperature of about 2000 ° C. or more, the aluminum oxide powder is not melted when passing through a heating furnace, and thus can be repeatedly used.

또한, 본 발명에서 2차가열로 (b)의 유리그릇 성형 적정온도를 약 650-750℃로 한정지은 것은 유리의 용융온도가 약 800℃이상인 점을 감안하여 유리가 용융되지 않고 형태 변형만이 가능한 온도를 채택한 것으로서 유리의 두께나 크기를 감안하여 온도와 가열로의 통과시간을 조절할 수도 있으며 3차로 (c)를 빠져나옴과 동시에 성형유리그릇에 공급되는 에어의 공급량을 성형유리제품의 두께나 크기에 따라 에어 공급시간을 조절하여 줄 수 있도록 한 것이다.In addition, in the present invention, the limit of the optimum temperature for forming the glass bowl of the secondary heating furnace (b) to about 650-750 ° C. is that the glass is not melted in view of the fact that the melting temperature of the glass is about 800 ° C. or more. By adopting the possible temperature, it is possible to adjust the passing time of the temperature and the heating furnace in consideration of the thickness and size of the glass, and the amount of air supplied to the molded glass vessel at the same time as exiting the third path (c). The air supply time can be adjusted according to the size.
