Technical Field

[0001] The utility model relates to the technical field of glass tube shaping, in particular to a glass tube inner diameter shaping machine. Background Art

[0002] Glass tubes used in fluorescent lamps, etc. are mainly manufactured by the Daner process. However, in the Daner process, there are restrictions on the diameter and thickness of the glass tubes that can be manufactured. For example, it is difficult to manufacture glass tubes with a large diameter and a large thickness by the Daner process. Specifically, the Daner process is a forming method in which molten glass is supplied to the side of a cylindrical forming body rotating around an inclined axis and the molten glass flowing down from the forming body is drawn along a transverse tube.

[0003] Therefore, when a glass tube with a large diameter and thickness is drawn by Danafar, it often bends due to its own weight, resulting in the inner diameter of some glass tubes not being straight and regular enough, affecting subsequent normal use. Therefore, a glass tube inner diameter shaping machine is proposed. Utility Model Content
