Description

Technical Field

[0001] The present application relates to the technical field of wires and cables, and in particular to a wire and cable stranding device. Background Art

[0002] Wire and cable stranding is the process of twisting together multiple strands of wire or cable to create an electrical connection. This twisting enhances the flexibility, durability, and tensile strength of the wire and cable. The stranding process is usually done using a stranding machine, which twists multiple strands of wire or cable together in a specific way to form a single, integrated wire or cable.

[0003] When existing wire and cable stranding equipment strands two wires, the position of the lead guide block on the outer surface of the stranding equipment is relatively fixed, resulting in a relatively fixed opening and closing angle of the stranded wire. As a result, when stranding wires of different sizes, the problem of mismatched stranding force is easily caused.

[0004] "A wire and cable twisting device with patent announcement number CN219832301U" discloses that by setting a bidirectional threaded rod and a guide block, it is helpful to adjust the opening and closing angle of the twisted wire, thereby avoiding the problem of mismatched force on the twisted wire when twisting wires of different sizes. However, the above-mentioned wire and cable twisting device does not limit the cable when in use. During the twisting process, the wires and cables will be tangled due to rotation. In addition, the wires and cables of the device pass directly through various holes during the twisting process, and the wires and cables may be damaged during the pulling process. Therefore, in order to solve the above problems, the present application provides a wire and cable twisting device.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
