Description

Technical Field

[0001] The utility model relates to the technical field of wire twisting machines, in particular to a metal wire twisting machine with an automatic tension balancing function. Background Art

[0002] During the stranding process, the balance of tension of each metal wire is crucial to the uniformity of the stranded wire. When the tension of the metal wires is balanced, they can be twisted together at the same speed and tightness. When manufacturing cable cores, the tension balance function can make multiple copper or aluminum wires twisted evenly, avoiding the situation where some metal wires are twisted too tightly and some are too loose, thereby ensuring the cross-sectional shape of the stranded wire is regular and the density on the circumference is uniform, improving the quality and appearance consistency of the stranded wire. When twisting multiple metal wires, it is necessary to ensure the tension balance between the metal wires, which is a great challenge for traditional stranding machines.

[0003] Metal wire stranding machines are mainly used to twist multiple metal wires together to form stranded wires with higher strength and specific properties. In the power industry, they are used to manufacture conductive cores in cables. Multiple copper or aluminum wires are twisted together to increase the current carrying capacity and mechanical strength of the wires to meet the power needs of high-voltage power transmission and various electrical equipment. In the communications field, they are used to manufacture signal lines of communication cables to ensure the stability and anti-interference of signal transmission. At the same time, in the construction, machinery manufacturing and automobile manufacturing industries, they are also used to manufacture various ropes, steel cables and spring steel wire products. These products play a key role in building hoisting, mechanical transmission and automobile suspension.

[0004] During the stranding process, unbalanced tension may cause the metal wire to overstretch or relax. Overstretching may reduce the diameter of the metal wire and degrade its mechanical properties, or even cause it to break. The relaxed metal wire may be loosely wound or jump out of the stranding position during the stranding process. However, traditional metal wire stranding machines have many shortcomings in tension control. During the stranding process, the tension of the metal wire is mainly adjusted by mechanical devices. This adjustment method has low accuracy and cannot meet the requirements of modern industry for high-precision control of stranding tension. When there are differences in the initial tensions of different metal wires, during the stranding process, the traditional stranding machine cannot adjust the tension in real time, which will lead to uneven tension of the stranded wire after stranding, affecting product quality. Moreover, when the stranding speed changes or the diameter of the metal wire changes, the traditional tension control method is difficult to adapt quickly, and the metal wire is prone to relaxation or overstretching. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a metal wire twisting machine with automatic tension balancing function, aiming to improve the problem in the existing technology that traditional twisting machines cannot adjust the tension in real time, which will lead to uneven tension of the twisted wire after twisting and affect product quality.
