Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, and more specifically, to a communication cable fixed-length cutting device. Background Art

[0002] Communication cables are used to transmit telephone, telegraph, fax documents, television and radio programs, data and other electrical signals. Communication cables are communication lines composed of a cable core twisted with multiple insulated wires or conductors and an outer sheath that protects the cable core from moisture and mechanical damage. In the current cable processing industry, the fixed-length cutting of communication cables is a crucial link, which is directly related to the quality and performance of cable products. However, in actual use, the existing fixed-length cutting devices for communication cables often face many challenges in the clamping and fixing of cables. First of all, as a soft wire material, the fixed limit at both ends of the cable is crucial to ensure the accuracy of cutting. However, the clamping devices equipped with many fixed-length cutting devices on the market are relatively simple in design, and often only rely on a few simple clamps or pressure plates to fix the cables. This simple clamping method may be barely competent when the cable is small in size or hard in material, but when facing cables with large size, soft material or smooth surface, its clamping effect seems to be inadequate. The problems caused by poor clamping effect are far more than that. When cutting cables, the blade needs to cut the cables quickly and accurately. However, if the cable moves or shakes during the cutting process, the impact of the blade may cause the cable to move, resulting in deviations in the cutting position. This will not only affect the accuracy of cable cutting, but may also damage the conductor or insulation layer inside the cable, thereby affecting the performance and service life of the cable. More seriously, if the cable shakes violently during the cutting process, it may also cause safety accidents. For example, the blade may deviate from the predetermined track at the moment of contact with the cable due to the shaking of the cable, thereby scratching the operator's fingers or arms. In addition, the shaking of the cable may also cause damage to the blade or equipment failure, further increasing production costs and maintenance difficulties. Utility Model Content

At the same time, the straight state can reduce the bending or twisting force on the cable during the cutting process, thereby reducing the stress concentration and damage inside the cable, thereby maintaining the structural integrity and performance stability of the cable.

[0025] The rotation of handle 10 causes threaded rod 8 to rotate, and the sleeve block 11 on the surface of threaded rod 8 moves downward, that is, the upper clamping plate 12 moves downward and approaches the lower clamping plate 5. The pressure when it is close to the cable surface makes the spring 6 compressed, and the slider 30 slides inside the slide groove 29.

[0041] The working principle and use process of this utility model:

[0042] When in use, the cable is placed on the surface of the lower clamping plate 5 inside the frame 12 and the frame 23, and then the staff turns the handle 10. The rotation of the handle 10 causes the threaded rod 8 to rotate through the connecting shaft 9, and the rotation of the threaded rod 8 causes the sleeve block 11 on its surface to move downward through the upper clamping plate 12 to gradually approach the cable on the surface of the lower clamping plate 5. Then, the pressure exerted by the upper clamping plate 12 when it touches the surface of the cable causes the telescopic rod 4 to contract inward, and the slider 30 slides synchronously inside the slide groove 29. At the same time, the spring 6 is in a compressed state. Then, the reaction force of the spring 6 resets the lower clamping plate 5, and the cable is clamped and fixed by the lower clamping plate 5 and the upper clamping plate 12.

[0043] When in use, the staff starts the hydraulic cylinder 15, and the force of the hydraulic cylinder 15 pushes the blade bracket 16 to move downward, thereby cutting the fixed cable. During the cutting process, the arc plate 20 first contacts the surface of the cable and is then affected by the force to cause the telescopic rod 19 to retract. At the same time, the spring 21 is in a compressed state, and then the cable is squeezed by the reaction force of the spring 21, so that it is always in a straight state.
