Description

TECHNICAL FIELD

[0001] The utility model relates to glass tube processing technical field more specifically, it relates to a glass tube pipe mill. BACKGROUND

[0002] In the technical field of glass tube pipe mill, the existing equipment has many technical problems to be solved, which seriously affect the processing quality and production efficiency of glass tube, mainly embodied in the following aspects:

[0003] Firstly, the traditional glass tube pipe mill has obvious deficiencies in the design of clamping mechanism, the existing technology usually adopts simple double-end clamping mode, and this fixed-specification clamping device cannot meet the processing needs of glass tube with different diameters, wall thicknesses and lengths in industrial production, especially when different specifications of glass tube need to be quickly switched, the fixed clamping structure is difficult to adjust effectively, which not only reduces the production efficiency, but also may cause glass tube deformation or damage due to improper clamping, and this poor adaptability of clamping mode seriously restricts the versatility and practical value of the equipment.

[0004] Secondly, although some improved equipment appears on the market, the flexible clamping of the outer wall of glass tube is realized by adding movable clamping mechanism, trying to solve the adaptability problem, but these devices are still rough in structure design, especially in the long-term operation process of the equipment, due to the influence of factors such as vibration and temperature change in the glass tube drawing process, the clamping mechanism is easy to loosen and deviate, and this defect in structural stability not only affects the processing precision of glass tube, but also may cause the glass tube to shake or deviate during drawing, which seriously affects the product quality and even causes production accidents.

[0005] More importantly, the existing technology generally adopts a single outer wall clamping mode, which ignores the particularity of glass material, glass tube is a kind of fragile hollow material, its wall is usually thin and has high brittleness, in the pipe drawing process, only relying on the outer wall clamping without inner wall support makes the glass tube bear uneven stress distribution, when the external clamping force is too large, it is easy to cause the glass tube to break, and when the force is too small, it cannot guarantee the processing stability, this single clamping mode not only increases the risk of glass tube breakage, but also limits the optimization space of pipe drawing process, which seriously affects the product qualification rate and production efficiency, in addition, due to the lack of inner wall support, the glass tube is easy to deform or collapse in the high-temperature drawing process, which further aggravates the difficulty of product quality control.
