Abstract
Description
Technical Field

[0002] The glass tube drawing furnace is a device used to produce glass tubes. In the glass industry, drawing is a common manufacturing process. After heating the glass block to a sufficiently high temperature, gravity and mechanical force are used to draw the glass block into a glass tube of the required diameter and length. The drawing furnace is usually composed of a heating furnace, a drawing mechanism, a cooling device, etc. After the glass is heated to a plastic state, the glass block is gradually elongated by the drawing mechanism to form the shape of a glass tube, and then the glass tube is quickly cooled and solidified by the cooling device, and finally the desired glass tube product is obtained.
[0003] At present, borosilicate glass round tubes are common in the market. They have high physical strength, good stability, high temperature resistance, acid and alkali resistance and other properties. They can be widely used in various fields such as aviation, medical, and chemical industry. However, round tubes have certain limitations in the application process and cannot meet the expected use requirements. Some occasions require glass square tubes. The existing drawing furnace can only straighten glass tubes with circular cross-sections. When using the existing drawing furnace to draw rectangular glass tubes, it is difficult to draw them into shape, and they are easy to twist and bend. It is difficult to process glass square tubes, and the labor intensity is high, which makes it difficult to meet people's use needs. Utility Model Content
