Abstract

The invention provides a curved glass manufacturing method for a glass hot-bending machine. The curved glass manufacturing method includes the steps of heating pretreatment, heating pre-compression treatment, cooling compression treatment and cooling decompression treatment. The heating pretreatment step includes heating a graphite die to a first set temperature by a plurality of heating stations;the heating pre-compression treatment step includes heating the graphite die to a second set temperature by at least two pre-forming stations, and compressing the graphite die to a first set pressure; the cooling compression treatment step includes compressing the graphite die to a second set pressure by a plurality of forming stations, and cooling the graphite die to a third set temperature; thecooling decompression treatment step includes cooling and decompressing the graphite die by a plurality of annealing stations. The curved glass manufacturing method for the glass hot-bending machineis provided with a plurality of heating stations, time setting of a single heating station is shortened, and productivity is improved under the condition of ensuring quality of glass products.

Description

technical field

[0001] The invention relates to the technical field of glass forming, in particular to a method for making curved glass used in a glass hot bending machine. Background technique

[0002] 3C products such as smart phones, smart watches, wearable smart products, dashboards, etc. have successively appeared 3D products, which have guided the development direction of 3D curved glass, such as flat touch screen mobile phones to 3D curved mobile phone screens, which have greatly opened up people's imagination. vision.

[0003] At present, in the glass hot bending machine, the flat glass placed in the graphite mold is heated and pressurized, so that the flat glass is bent into the designed curved glass according to the cavity of the graphite mold. The steps in the existing thirteen-station glass hot bending machine include preheating the graphite mould, pressurizing and heating the graphite mould, and cooling and shaping the graphite mould. But in the existing thirt...
