Embodiment Construction

[0039] Below in conjunction with each accompanying drawing, the present invention is described in detail.

[0040] A manufacturing process for a preform, comprising the following steps:

[0041] 1) The mandrel is installed on the two rotating chucks of the deposition bed to carry out the deposition operation of the loose body;

[0042] 2) After the deposition operation is completed, the deposition bed is rotated 90° so that the loose body is vertically arranged;

[0043] 3) The loose body is removed from the deposition bed, and moved into a heating furnace for sintering operation to obtain a preform.

[0044] In the manufacturing process of the present application, after the deposition of the loose body is completed, the deposition bed is rotated 90° so that the loose body is vertical, and the loose body can be quickly vitrified (sintering operation) after the loose body is removed, thereby greatly improving the processing efficiency.

[0045] In this embodiment, one end of ...

Abstract

The application discloses a manufacturing process of a prefabricated rod, which comprises the following steps: 1) installing the core rod on two rotary chucks of the deposition bed to perform the deposition operation of the loose body; 2) after the deposition operation is completed, placing the deposition bed Rotate 90°, so that the loose body is vertically arranged; 3) Move the loose body out of the deposition bed, and move it into a heating furnace for sintering operation to obtain a preform. In the manufacturing process of the present application, after the deposition of the loose body is completed, the deposition bed is rotated 90° so that the loose body is vertical, and the loose body can be vitrified quickly after the loose body is removed, thereby greatly improving the processing efficiency.

Description

technical field [0001] The invention relates to the field of preformed rods, in particular to a manufacturing process of the preformed rods. Background technique [0002] When manufacturing the preform, the outer cladding (loose body) of the optical fiber preform is first manufactured by the OVD method, and then the loose body is removed and put into a heating furnace for vitrification. [0003] Loose body and vitrification are two completely independent steps, and the transportation of loose body and repeated disassembly and assembly operations will greatly reduce the processing efficiency. Contents of the invention [0004] Aiming at the above problems, the present invention proposes a preform manufacturing process. [0005] The technical scheme that the present invention takes is as follows: [0006] A manufacturing process for a preform, comprising the following steps: [0007] 1) The mandrel is installed on the two rotating chucks of the deposition bed to carry out...
