Technical Field

The invention relates to optical fiber perform processing equipment, in particular to an optical fiber perform segmentation and end face bevel cutting device.

Background

Along with the development of the optical fiber perform industry, the outer diameter of the optical fiber perform is larger, the quality is larger and larger, the hardness of the cut surface is increased, and the cutting process of the large optical fiber perform is puzzled on the development of enterprises.

The cutting process is an auxiliary process in the preform production process, and the cutting process needs to be performed for many times in the whole process of preform production.

Two cutting processes exist: one is flame cutting; the other is mechanical cutting. The cutting rate of the cutting machine in the actual production process can influence the production time of the whole preform, and meanwhile, the cutting quality of the cutting machine can cause certain losses of semi-finished products and finished products. Therefore, the cutting equipment and process are an important issue for the preform manufacturing enterprises of today.

In the existing casing process, the length of the core rod of the prefabricated rod after longitudinal extension generally reaches more than 3 meters, so that related segmentation is needed before the next process, vacuumizing and exhausting of a rear end procedure are facilitated after segmentation, an exhaust bevel opening needs to be formed in the end face of the prefabricated rod, and after all segmentation and exhaust bevel openings are formed, the end face and the bevel opening are required to be free of breakage and edge breakage.

When the existing mechanical cutting is used for cutting an oblique opening, a rod body is directly held by hand to be close to a rotary blade, the requirement on an operator is high, and the edge is easily broken and damaged after the cutting.
