Mold for bending and forming thick glass tube and using method thereof

Abstract

The invention discloses a mold for bending and forming a thick glass tube and a using method thereof, and belongs to the technical field of glass tube processing. Through the arrangement of an anti-deformation heat-assisting piece, when a glass tube is bent, the bent part of the glass tube can be directionally and uniformly heated through high-temperature heat carrier particles, so that the glass tube can be uniformly heated. When the glass tube is bent, the glass tube can be prevented from being sunken and deformed inwards through the high-temperature heat carrier particles. Through the arrangement of hard and soft rod limiting pieces, after the glass tube is heated and softened, heat conduction anti-extrusion rods can be pulled to slide into a heat preservation adjusting cylinder, so that a flowing space can be provided for the high-temperature heat carrier particles, the heat carrier particles are prevented from extruding the glass tube outwards to cause deformation of the glass tube when the glass tube is bent, and the cooling and shaping efficiency after the glass tube is bent can be improved. Residual heat in the high-temperature heat carrier can be recycled, and the energy-saving and environment-protection performance is improved.

Description

technical field [0001] The invention relates to the technical field of glass tube processing, and more specifically relates to a mold for bending and forming a thick glass tube and a use method thereof. Background technique [0002] Glass tube is a kind of non-metallic tube, a kind of glass based on sodium oxide, boron oxide and silicon dioxide. Its good performance has been recognized by all walks of life in the world. Compared with ordinary glass, it has no toxic side effects, 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 our country is another new revolution in the basic material industry. [0003] Glass tubes can generally be divided into ordinary glass tubes, chemical glass tubes, neutral gla...

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
