Description

Technical Field

[0001] The invention relates to the technical field of cable processing, and in particular to a method and a device for processing special-shaped wires. Background Art

[0002] In the development of cable technology today, special-shaped cables, as a type of cable with special structure and performance, play an important role in the fields of communication, power transmission, etc. This cable is usually composed of a central monofilament and multiple outer monofilaments. The outer monofilaments are tightly wound on the surface of the central monofilament in a spiral or other form to form a unique composite structure. However, existing special-shaped cables have significant technical bottlenecks in terms of structural strength and bonding strength.

[0003] The central monofilament, as the core of the cable, bears the main mechanical strength and conductive function, while the outer monofilament plays a role in enhancing the mechanical properties and protection of the cable. However, the bonding force between the central monofilament and the outer monofilament is low, resulting in insufficient overall structural strength of the cable. In practical applications, this problem of low structural strength manifests itself in that when the cable is stretched, bent, or subjected to external impact, the central monofilament and the outer monofilament are prone to relative sliding or separation, thereby affecting the stability and service life of the cable.

[0004] In order to solve this problem, the existing technology usually adopts the method of reprocessing and then coating to improve the bonding force between the central monofilament and the outer monofilament. However, this process has many shortcomings: first, due to the particularity of the structure of the heterosexual cable, it is difficult for the glue to evenly and fully penetrate into the tiny gap between the central monofilament and the outer monofilament, resulting in an unsatisfactory effect of improving the bonding force; secondly, the existing coating and injection process often cannot achieve effective sealing, which not only leads to waste and overflow of glue, but also may cause pollution of the internal structure of the cable, further affecting the performance of the cable. Furthermore, the overflow of glue will also lead to a decrease in the appearance quality of the cable, increase production costs, and have potential impacts on the environment. Therefore, the existing heterosexual cables still need to be improved in terms of structural strength, bonding improvement, and production efficiency. Summary of the invention
