An air grid device and a method for cooling double-curved tempered glass using the device

Abstract

The invention discloses an air grid device and a method for cooling double-curved tempered glass by using the device. The device includes upper and lower air grids, the upper / lower air grids include an air outlet plate, and a cavity is opened inside the air outlet plate. A height adjustment unit is arranged on the surface, the height adjustment unit includes an adjustment screw sleeve, the lower end of the adjustment screw sleeve is hinged with the air outlet plate through a hinge, an adjustment screw is screwed on the adjustment screw sleeve, and a connection block is sleeved on the adjustment screw; A first tempered pipe joint is fixed in the rectangular space enclosed by four adjacent adjusting screw sleeves on the air plate, and the upper air outlet of the first tempered pipe joint passes through the flexible air pipe and the air outlet holes evenly opened on the top grid assembly connected. The invention has simple installation and disassembly, simple adjustment of the air outlet surface, effectively shortens the adjustment time, ensures that the double-curved glass to be tempered is evenly heated, and improves the yield of the double-curved tempered glass, especially the double-curved tempered glass with a thickness of 3.2 mm. The yield of glass can achieve safe production and reduce production costs.

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 production process of physical tempered glass, an air grid is 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 diversified requirements for the structure and appearance of tempered ...

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%.
