Cutting head technique for spiral fluorescent lamp tube

Abstract

The invention relates to a head cutting process for a spiral fluorescent tube, which belongs to the field of spiral fluorescent tube production. The open end of a glass tube of the spiral fluorescent tube is arranged vertically and downwardly; a flame tube is inserted into the glass tube from below for heating; the outer wall of the fluorescent tube is scratched while heating or is scratched once the heating is stopped; and in addition, a flat push rod is used to push off the glass tube to be cut in the flat pushing mode under the condition that the position of the vertically downward open end of the glass tube of the spiral fluorescent tube is kept unchanged. Due to the even heating, the cut glass port has good smoothness. As the fluorescent tube is arranged vertically, the mechanized cutting becomes more feasible; while the flame is burning in the fluorescent tube, thereby saving production steps, consequently improving the labor productivity from all aspects, and also providing a technological process proposal for the further invention and perfection of a head cutting machine.

Description

technical field [0001] The invention relates to the field of manufacturing spiral lamp tubes, in particular to a head cutting process for spiral fluorescent lamp tubes. Background technique [0002] After bending the straight glass tube into a spiral glass lamp tube through the bending process, the straight tubes at both ends are still very long. Usually, the length of the lamp tube is placed horizontally, then scratched with a sand wheel and then cut off to complete the cutting, or the lamp tube is placed horizontally, and then locally heated on the outside of the lamp tube to be cut, and then cutting. This traditional method, because the heating is difficult to be uniform, can only be done manually, which limits the mechanization of the cutting process to some extent, thereby limiting the improvement of labor productivity. Contents of the invention [0003] Compared with the prior art, the purpose of the present invention is to make the heating of the lamp tube more un...
