Technical Field

The invention relates to the field of optical fiber cutter accessories for engineering, in particular to an optical fiber cutter blade accessory which crushes or knocks off optical fibers along a scratch cut after scratching the surface of the excircle of the optical fiber to form an optical fiber end face meeting the engineering standard.

Technical Field

Optical fibers have been widely used in the fields of communication, medical treatment, sensors, navigation, and the like, and the main material for manufacturing the optical fibers is high-purity quartz, so that a special method is required for connection between the optical fibers; at present, two methods are mainly adopted in the engineering field: one is physical connection, namely, the optical fibers to be connected are accurately aligned and fixed, which is called cold connection; the other method is that a group of precisely aligned optical fibers are further heated at high temperature to reach the melting point of the optical fibers so that the two optical fibers are fused, which is called fusion splicing; the radial cross section of the optical fiber must be planarized before cold-splicing and fusion splicing, and light can be effectively transmitted only if the radial cross sections of the optical fibers can be attached to each other as much as possible during alignment. In communication optical fiber engineering field, this kind of terminal surface processing tool of optic fibre is the optical fiber cutting knife, and its principle is: the outer circle of the optical fiber is scratched by using the blade edge of the blade, so that a notch perpendicular to the axis of the optical fiber is formed, and then external force is applied to expand along the notch direction until the optical fiber is broken.

The optical fiber is made of high-purity glass, namely silicon dioxide, the Mohs hardness of the optical fiber is about 7, and the optical fiber is a hard substance in the nature, so the material hardness of a cutting blade of the optical fiber is more than 7, the Mohs hardness of a currently widely-used hard alloy material is between 8.2 and 9.3, the current market price is between 1 yuan and 5 yuan to 2000 yuan of RMB, and the following disadvantages exist:

1. although the circular blade made of tungsten alloy is suitable for machining the cutting edge of the circular arc-shaped blade, the hardness of the hard alloy material popular in the market is not as high as that of an artificial single crystal for cutting a high-quality optical fiber end face.

2. The hard alloy circular optical fiber cutting knife blade with both sharpness and hardness has higher cost and the current market price is more than 1000 yuan.

3. The circular blade is an integral single blade, and the abrasion condition of each cutting edge surface in use cannot be observed under normal conditions (can be observed under the condition of using a microscope), so that a user cannot easily and accurately judge whether the cutting edge surface can be continuously used, the actual service life of the blade and the like.

4. When the blade is replaced, a user can only replace the circular blade integrally and cannot replace the blade with a worn cutting edge independently, so that the cost is saved; therefore, the circular blade cannot satisfy the increasingly diversified demands of users.

Disclosure of Invention

In view of the above problems, an object of the present invention is to provide a clamp for a blade of an optical fiber cutting blade and a clamp blade using the same, which are used to replace and supplement a circular optical fiber cutting blade of tungsten alloy with different quality in the existing market, wherein a linear blade and a linear blade with low clamping processing cost are generally made of an artificial single crystal material with hardness higher than that of metal alloy, and the artificial corundum single crystal (sapphire, ruby) has hardness second to diamond and melting temperature of 2050, has good mechanical properties, chemical stability and optical properties, can be used to manufacture a very excellent cutting edge through a special professional processing technology, does not generate flexural deformation when the thickness is less than 0.10 mm, and has a very smooth cutting edge and good durability; the blade can also be made of alloy materials according to requirements.

The linear blade is installed on the blade fixture, a plurality of blades can be installed on one blade fixture, 4 blades are usually installed, at least two edge cutting edges of each blade are used as cutting edges, each fixture blade at least has 8 cutting edges for cutting, the fixture blade is installed on the existing guide rail type cutting blade holder, the height of the blade holder is adjustable, and the fixture blade has the same geometric dimension as the existing monomer alloy blade, so that the existing alloy circular blade can be replaced without obstacles, and the modes of replacing the blades, replacing the cutting edges and adjusting the height of the blades are the same as the existing circular blade.

The invention has the significance that the blade which is more suitable for being made into the blocky linear cutting edge made of the optical fiber cutter blade material is clamped into the size of the existing optical fiber cutting blade in a blade clamp mode, the hardness advantages of the materials are utilized, the existing processing modes of the materials are also taken care of, and the application is realized in a low-cost mode.

The present invention has the following advantageous effects

1. The hardness of the material on the whole is higher than that of the hard alloy; the average hardness of the hard alloy blade is not high due to the fact that the market proportion of the hard alloy blade with low price (lower than 1000 yuan) is the largest at present, and the overall market proportion of the high-quality hard alloy blade is not high due to high cost and high price; because of the nature of the artificial single crystal material, the hardness of the material is stable above 9.0 and is not influenced by price factors, so that the optical fiber cutter blade clamp using the artificial single crystal material blade and the clamp blade using the clamp have higher hardness and are more stable.

2. A longer service life; according to the existing data, the service life of the cutting edge of the optical fiber cutting knife blade made of the artificial single crystal material is 2 to 3 times of that of the hard alloy, and the cutting frequency of a single cutting edge is more than 1 ten thousand times.

3. Compared with hard alloy with high hardness, the artificial single crystal material has lower cost; due to the large application of the artificial single crystal material (such as a scratch-proof screen of a mobile phone) and the improvement of the process, when the artificial single crystal material is used as a blade material of an optical fiber cutter, the cost of the blade is mostly concentrated on the shape processing working hour due to the small volume of the blade, and the value ratio of the material per se is low.

4. The blade is processed into a smaller block-shaped structure, so that the cost is further optimized, and the use requirement of independently replacing the cutting edge is met.

5. As the clamp is of a metal structure, the clamp is almost free from any abrasion in the use process and can be reused almost indefinitely, and when the blade is abraded, the blade which is used as the clamp blade can be replaced by a relatively cheap blade, so that the cost is further saved.

6. The clamp blade can be compatible with the existing hard alloy blade material, and only the hard alloy needs to be processed into a shape suitable for the clamp.
