Problems solved by technology

[0003] In the prior art, the basic principle of the quartz tube rod straightening device is a Y-shaped graphite fork or a pair of graphite rollers to adjust the curvature. This method has the defect of inconvenient operation or the rejection of the quartz tube rod during the straightening process. In addition, these methods have high requirements for operators, and the probability of poor bending of quartz tube rods caused by human operation factors is relatively high, thus affecting the preform production process. Detrimental effect on stability and final fiber performance

Abstract

The invention belongs to the technical field of optical fiber manufacturing processes, and discloses a device and a method for straightening a quartz tube rod. The device comprises a supporting platform and a straightening body. The supporting platform is located below the quartz tube rod to be straightened. The straightening body is provided with a supporting plane and a grinding end face, the straightening body is located between the supporting platform and the quartz tube rod, the supporting plane is attached to the table top of the supporting platform, and the grinding end face makes contact with the to-be-straightened position of the quartz tube rod and is used for grinding the bending point. The device is simple in structure and convenient to operate, an operator does not need to have operation experience, and a good straightening effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of optical fiber manufacturing technology, in particular to a device and method for straightening a quartz tube rod. Background technique [0002] Optical fiber preform is the core raw material for manufacturing quartz series optical fibers. In the process of manufacturing optical fiber preforms by chemical vapor deposition and plasma chemical methods, since the wall thickness of the quartz tube rods used is usually thin, it is easy to cause the surface of the tube wall to bend under the condition of long-term high-temperature heating. Practice has proved that the use of quartz tube rods with poor bending grades to manufacture optical fiber preforms will not only cause problems in the manufacturing process, such as partial or overall bending of the preforms, which will cause subsequent processing to be unable to proceed normally, and even if it does not affect the subsequent The processing of the process wi...
