Description

Technical Field

[0001] This utility model relates to the field of optical fiber production technology, and in particular to a cutting tool for optical cable production. Background Technology

[0002] Optical cables are generally called optical fibers, or simply optical fibers. An optical cable consists of a cable core made up of several optical fibers and an outer sheath. Compared with traditional symmetrical copper circuits and coaxial copper circuits, optical fibers have a much larger transmission capacity, less attenuation, longer transmission distance, and smaller size. They are currently the most promising communication transmission medium. In the optical cable processing and production process, cutting equipment is needed to cut the fiber into sections to meet the requirements of use.

[0003] Existing optical cable cutting tools typically cut optical cables by controlling the vertical downward movement of the cutter head. However, due to the complex internal structure of optical cables, which contains multiple sets of precisely arranged optical fibers and are tightly wrapped by an external protective sleeve, in actual operation, there is a problem that a single cut may not be able to completely sever all optical fibers, leaving tiny connection points, which affects the transmission performance and overall quality of the optical cable. Utility Model Content

[0004] The main objective of this invention is to provide a cutting tool for optical cable production, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

A first electro-hydraulic rod is fixedly installed on the top wall of the frame. A first cutting blade is fixedly installed at the output end of the first electro-hydraulic rod. A connecting rope is fixedly connected to the front end of the first cutting blade, and a second cutting blade is fixedly connected to the tail end of the connecting rope. A pull rod is fixedly installed at the front end of the second cutting blade, and a piston is fixedly installed at the tail end of the pull rod. A cylinder is fixedly installed on the inner side wall of the frame, and both the pull rod and the piston are movably connected to the inner wall of the cylinder. Two sets of second electro-hydraulic rods are fixedly installed on the inner side wall of the frame. Movable blocks are fixedly installed at the output ends of the two sets of second electro-hydraulic rods, and the connecting rope is movably connected to the outer surface of the movable blocks.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example

[0020] like Figure 1-5 As shown, a cutting tool for optical cable production includes a frame 1. A base 2 is fixedly installed on the bottom wall of the frame 1, and a limit frame 3 is fixedly installed on the top of the base 2. A first electro-hydraulic rod 4 is fixedly installed on the top wall of the frame 1. A first cutting blade 5 is fixedly installed at the output end of the first electro-hydraulic rod 4. The first electro-hydraulic rod 4 is used to drive the first cutting blade 5 to move up and down, thereby achieving the purpose of vertical cutting. A connecting rope 6 is fixedly connected to the front end of the first cutting blade 5, and a second cutting blade 7 is fixedly connected to the tail end of the connecting rope 6. The first cutting blade 5 and the second cutting blade 7 are connected together by the connecting rope 6. The length of the connecting rope 6 is fixed. When the first cutting blade 5 moves the front end of the connecting rope 6 downwards, the tail end of the connecting rope 6 pulls the second cutting blade 7 out of the limiting frame 3, so that the first cutting blade 5 can be smoothly inserted into the limiting frame 3. A pull rod 8 is fixedly installed at the front end of the second cutting blade 7, and a piston 9 is fixedly installed at the tail end of the pull rod 8. A cylinder 10 is fixedly installed on the inner wall of the frame 1, and both the pull rod 8 and the piston 9 are movably connected to the inner wall of the cylinder 10. The cylinder 10 is filled with a certain volume of gas at its tail end. When the connecting rope 6 pulls the second cutting blade 7, under the connection of the pull rod 8... This causes piston 9 to move towards the tail end of cylinder 10. As piston 9 moves, it compresses the gas. When the tension of connecting rope 6 on the second cutting blade 7 is suddenly released, the compressed gas expands rapidly, converting its internal energy into kinetic energy, pushing the second cutting blade 7 towards the limiting frame 3. Two sets of second electro-hydraulic rods 11 are fixedly installed on the inner wall of frame 1. Movable blocks 12 are fixedly installed at the output ends of the two sets of second electro-hydraulic rods 11, and connecting rope 6 is movably connected to the outer surface of the movable blocks 12. The second electro-hydraulic rods 11 can drive the movable blocks 12 to move horizontally, and the horizontal movement of the movable blocks 12 pulls the connecting... When the rope 6 is in motion, the front end of the connecting rope 6 is restricted by the first electric hydraulic rod 4 and cannot move, while the tail end of the connecting rope 6 will pull the second cutting blade 7 until the second cutting blade 7 disengages from the limiting frame 3, thereby achieving the purpose of both the first cutting blade 5 and the second cutting blade 7 disengaging from the limiting frame 3, so as to facilitate material feeding. The second electric hydraulic rod 11 is controlled to extend rapidly, so that the movable block 12 is quickly separated from the connecting rope 6. The tension of the connecting rope 6 on the second cutting blade 7 is suddenly released, and then, with the cooperation of the gas in the cylinder 10, the second cutting blade 7 is quickly inserted into the limiting frame 3, thereby achieving the purpose of horizontal cutting.

[0021] Two sets of springs 13 are fixedly installed on the outer surface of the limiting frame 3, and the tail end of the spring 13 is fixedly connected to the front end of the second cutting blade 7. By setting the spring 13, when the connecting rope 6 pulls the second cutting blade 7 horizontally to disengage from the limiting frame 3, the spring 13 will be stretched. When the tension is released, the spring 13 can assist the second cutting blade 7 to rebound. Two sets of first limiting rods 14 are fixedly installed on the outer surface of the tail end of the cylinder 10, and the connecting rope 6 is movably connected to the outer surface of the first limiting rods 14. A second limiting rod 15 is fixedly installed on the inner side wall of the frame 1, and the connecting rope 6 is connected to the outer surface of the first limiting rods 14. The first limiting rod 14, the second limiting rod 15, and the third limiting rod 16 are fixedly installed on the inner wall of the frame 1. The connecting rope 6 is movably connected to the inner wall of the third limiting rod 16. By setting the first limiting rod 14, the second limiting rod 15, and the third limiting rod 16, the vertical downward pulling force of the first cutting blade 5 on the connecting rope 6 can be converted into a horizontal pulling force of the connecting rope 6 on the second cutting blade 7. Two sets of support frames 17 are fixedly installed at the front and rear ends of the limiting frame 3. Two sets of movable rollers 18 are rotatably connected to the opposing surfaces of the two sets of support frames 17. The first electro-hydraulic rod 4 and the second electro-hydraulic rod 11 are electrically connected to an external power supply through corresponding control switches. The first electro-hydraulic rod 4 and the second electro-hydraulic rod 11 are both existing technologies, and their specific structures, working principles, and electrical connections are not detailed here.

[0022] It should be noted that this utility model is a cutting tool for optical cable production. In use, the second electro-hydraulic rod 11 is first controlled to retract rapidly, causing the movable block 12 to horizontally pull the middle of the connecting rope 6 until the second cutting blade 7 disengages from the limiting frame 3. Then, the front end of the optical cable is inserted between the two sets of movable rollers 18 at the front end of the limiting frame 3. The optical cable is then pushed so that its front end passes between the two sets of movable rollers 18 at the rear end of the limiting frame 3. After the optical cable is placed, the second electro-hydraulic rod 11 is controlled to extend rapidly, causing the movable block 12 to quickly separate from the connecting rope 6. Then, under the action of the gas inside the cylinder 10, the second cutting blade 7 quickly inserts into the limiting frame 3, thus completing one water... After a flat cut, the first electric hydraulic rod 4 operates, and its front end drives the first cutting blade 5 to vertically insert into the limiting frame 3, thereby completing a vertical cut. Through two cuts, it is ensured that the optical cable is completely and accurately cut, avoiding leaving tiny connection points, thus improving the cutting quality of the optical cable and the reliability of subsequent use. Then, the two cut sections of optical cable are pulled out from the movable rollers 18 at both ends of the limiting frame 3. The first electric hydraulic rod 4 is controlled to retract, so that the first cutting blade 5 is reset. When the first cutting blade 5 is reset, the tension of the connecting rope 6 on the second cutting blade 7 is also released, so that the second cutting blade 7 is also reset. The above operation is repeated to perform the next cut.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
