US 9,630,870 B2 · Method for manufacturing columnar curved tempered glass

Abstract

The present invention discloses a method for processing a columnar curved tempered glass. The method specifically comprises the following steps. Bending and tempering of the high temperature flat glass are divided into two stations. Bending is firstly carried out on the high temperature flat glass output by a heating furnace; the columnar extending direction of the curved glass is perpendicular to the direction the glass output from the heating furnace in the bending process, and then the formed curved glass is output to a tempering station in the columnar extending direction thereof to undergo tempering. In the present invention, bending and tempering of the high temperature flat glass are completed by two stations to break the normal procedure that bending and tempering are carried out by a single bending device intensively, thereby providing a novel technological approach for processing the columnar curved tempered glass.

Dependent claims

A method for forming a curved tempered glass comprising:

bending a previously heated flat glass in a bending station thereby forming a curved glass;
tempering the curved glass in a tempering station, wherein the tempering station is separate from the bending station;
wherein the flat glass is previously heated in a heating furnace and then is conveyed along a first direction out of the heating furnace and into the bending station;
wherein the heated flat glass is subsequently bent in the bending station so that the curved glass extends along a second direction that is perpendicular to the first direction;
and
wherein the curved glass exits the bending station and enters the tempering station along the second direction;
and
wherein the heated flat glass is bent in the bending station via a bending mechanism that comprises glass supporting rollers and transferring scroll wheels and wherein each transferring scroll wheel is arranged between two adjacent glass supporting rollers.
