Method for cutting glass by virtue of ultra-high water pressure

Abstract

The invention discloses a method for cutting glass by virtue of ultra-high water pressure. The method is characterized by comprising the following steps: (1) overlapping multiple pieces of thin plate glass and bonding into a whole; and (2) fixing the bonded thin glass and cutting by virtue of water-sand mixed jet, wherein water is pressurized by virtue of water-sand mixed jet, the pressurized pressure range is 60MPa-80MPa, the mass ratio of water to sand is 1:0.5 and the sand is 200-mesh sand. According to the method disclosed by the invention, the multiple pieces of thin plate glass are overlapped and bonded into a whole, the multiple pieces of glass can be cut once, the production efficiency is greatly improved and meanwhile, the cutting capability of the water-sand mixed jet is strong, the breaking of the glass is not needed after the cutting is completed, the artificial operating loss is reduced and the yield rate is increased.

Description

technical field [0001] The invention relates to the technical field of glass cutting, in particular to a method for ultra-high hydraulic pressure glass cutting. Background technique [0002] At present, in the glass product industry, glass knives such as diamond knives, diamond knives, etc. are generally used for cutting thin flat glass (0.33 mm ~ 1.5 mm). With this method, only one piece can be cut at a time, and the cutting efficiency is low; and when cutting special-shaped or curved surfaces, the cutter head of the glass knife is inconvenient to rotate, and the bending angle is relatively large, so it cannot cut products with large or multiple angles well. . And after this cutting, the edge waste still stays on the finished product, and it is easy to produce fragments and cracks in the process of removing the edge waste when breaking the pieces. Moreover, thin flat glass itself is a fragile product. Using traditional cutting methods, the efficiency and yield rate of mas...

With this method, only one piece can be cut at a time, and the cutting efficiency is low; and when cutting special-shaped or curved surfaces, the cutter head of the glass knife is inconvenient to rotate, and the bending angle is relatively large, so it cannot cut products with large or multiple angles well.

And after this kind of cutting, the edge waste remains on the finished product, and it is easy to produce fragments and cracks in the process of breaking the pieces to remove the edge waste

Moreover, thin flat glass itself is a fragile product. Using traditional cutting methods, the efficiency and yield rate of mass production are low
