Wind grid device and method for cooling hyperbolic curved tempered glass by using same

Abstract

The invention discloses a wind grid device and a method for cooling hyperbolic curved tempered glass by using the same; the wind grid device comprises an upper wind grid and a lower grid; the upper / lower wind grids comprise a wind outlet board; the interior of the wind outlet board is provided with a cavity, and the surface of the wind outlet board is provided with a height adjusting unit; the height adjusting unit comprises adjusting screw sleeves; the lower ends of the adjusting screw sleeves are hinged with the wind outlet board into a whole through hinges; the adjusting screw sleeves are screwed with adjusting screws; the adjusting screws are sleeved with connecting blocks; a rectangular space enclosed by the four adjacent adjusting screw sleeves on the wind outlet board is internally fixedly provided with a first tempering pipe connector, a wind outlet at the upper part of the first tempering pipe connector communicates with wind outlet holes through a flexadux, and the wind outlet holes are uniformly formed in a top grid. The wind grid device is simple to mount and dismount, the wind outlet curved surface is simple to adjust, the adjustment time is effectively shortened, hyperbolic curved glass to be tempered is guaranteed to be heated uniformly, the yield of the hyperbolic curved tempered glass is increased, especially, the yield of the hyperbolic curved tempered glass with the thickness of 3.2 mm is increased, and the production cost is reduced while safe production is achieved.

Description

technical field [0001] The invention relates to the production of double-curved tempered glass, in particular to an air grid device for cooling the double-curved tempered glass, and also relates to a method for cooling the double-curved tempered glass by using the air grid device. Background technique [0002] Tempered glass is a kind of prestressed glass, which has the advantages of high strength, good thermal stability and safe use, so it is widely used in high-rise building doors and windows, glass curtain walls, lighting ceilings, automotive glass and other fields. Existing tempered glass is divided into physical tempered glass and chemical tempered glass according to its production process. In the process of physical tempered glass production, air grids are usually used to rapidly cool the glass coming out of the heating furnace. At present, with the development of society, people have more and more diverse requirements for the structure and appearance of tempered glass...

AI Technical Summary

Problems solved by technology

Because some existing air grilles cannot be adjusted in height, when producing double-curved tempered glass with different shapes, they need to be replaced with air grilles with different air outlet surfaces, which increases the investment cost and takes up space for storing the disassembled air grills; and the When disassembling the wind-like grille, the flexible air ducts on the air outlet plate need to be removed one by one, and then the air outlet plate can be removed. The workload is heavy and the downtime is long; some air grilles are arranged in rows, and each row The grille is a whole. Since the double-curved glass is a curved structure, although the grille has been adjusted many times (the adjustment time can be as long as more than an hour), the shape of the air outlet surface is still very different from that of the double-curved glass to be tempered. , can not meet the production requirements, it is easy to cause uneven heating of the double curved tempered glass during the cooling process, resulting in the breakage of the double curved tempered glass, which greatly reduces the yield of the double curved tempered glass, especially for thinner thickness such as thickness 3.2mm Double-curved tempered glass, the existing yield of double-curved tempered glass with a thickness of 3.2mm is only 70% to 75%.
