Problems solved by technology

[0004] In the prior art, for the bending of the glass tube, flame heating is often used to heat the bending part of the glass tube outside the glass tube, so that the glass tube is heated and softened, and then the glass tube is bent, which is not only easy to make The glass tube is heated unevenly, and when the glass tube is bent, especially for a thick glass tube with a large diameter, the glass tube is hollow inside, which may easily cause the glass tube to sag inward and deform

Abstract

The invention discloses a mold for bending and forming a thick glass tube and a method for using the same, which belongs to the technical field of glass tube processing. The invention adopts the arrangement of anti-deformation and heating aids so that when the glass tube is bent, the high temperature can be passed The heat carrier particles heat the bend of the glass tube in a directional and uniform manner, so that the glass tube can be heated evenly. The setting of hard and soft limiting rods makes it possible to pull the heat-conducting anti-extrusion rod to slide into the heat preservation adjustment cylinder after the glass tube is heated and softened, which not only provides a flow space for high-temperature heat carrier particles, but also prevents the glass tube from being bent. The heat carrier particles extrude the glass tube outward, causing the glass tube to deform, and can improve the efficiency of cooling and shaping the glass tube after bending, and can also recover and reuse the remaining heat in the high-temperature heat carrier, improving energy saving and environmental protection performance.

Description

technical field [0001] The invention relates to the technical field of glass tube processing, and more particularly, to a mold for bending and forming a rough glass tube and a method for using the same. Background technique [0002] Glass tube is a kind of non-metallic tube, which is a kind of glass with sodium oxide, boron oxide and silicon dioxide as the basic components. Its good performance has been recognized by all walks of life in the world. Compared with ordinary glass, it has no toxic and side effects, and its mechanical properties, thermal stability, water resistance, alkali resistance, acid resistance and other properties are greatly improved. It can be widely used in chemical industry, aerospace, Military, family, hospital and other fields have good promotion value and social benefits. The appearance of this kind of glass in my country is another new revolution in the basic material industry. [0003] Glass tubes can generally be divided into ordinary glass tubes...
