Description
Technical Field
The invention belongs to the technical field of optical cable processing, and particularly relates to a high-speed preparation method and system suitable for an 8-shaped optical cable.
Background
The 8-shaped optical cable is a communication cable product integrated with an optical fiber unit, a water-blocking material, metal tape armoring and steel wire stranded wires, and generally comprises a cable core part, a sling part and a hanging part for the conventional 8-shaped optical cable, and the cable core part and the hanging part are usually provided with the high-strength steel wire stranded wires, so that the 8-shaped optical cable can reliably complete self-supporting overhead arrangement, and the installation cost of the optical cable is reduced while good mechanical performance and temperature performance are ensured.
During actual preparation, the sizes of the cable core part, the sling part and the hanger part of the 8-shaped optical cable can be different according to different application scenes and application requirements, and hundreds of common combination types are provided. Due to the difference of the size combination types, the quality control of the existing optical cable production line has obvious difference when 8-shaped optical cables of different types are prepared, which is mainly because some equipment is designed according to the special design of one or more types of 8-shaped optical cables, and the compatibility of the equipment is poor.
Meanwhile, in the preparation process of the 8-shaped optical cable, the feeding precision of the steel strand and the cable core needs to be guaranteed in a key mode, and the preparation precision of the whole optical cable and the quality of a formed product are directly affected. However, in the preparation process, the steel strand is abraded due to friction between the steel strand and a die or a guide wheel in the feeding process because the preparation flow and the process route are long. On one hand, the steel strand feeding speed is reduced, and the steel strand shakes in the feeding process, so that the optical cable is uneven in diameter and even has the defects of bulging, stretching and the like; on the other hand, the surface of the steel strand is often plated with a zinc layer, and in the traditional wire feeding process of the steel strand, the zinc layer is directly contacted with a mould or a guide wheel, so that the zinc layer is peeled off and damaged, which not only affects the antirust performance of the optical cable, but also the peeled zinc powder and zinc layer can fall off and coat in the formed outer sheath, so that the insulating performance of the optical cable is greatly reduced, the breakdown condition of the optical cable during subsequent high-voltage spark detection can be caused, the safe use of the optical cable is affected, and the number of optical cable defective products and the preparation cost of the optical cable are increased.
In addition, when the mark is impressed after the optical cable extrusion molding sheath is formed and after the optical cable extrusion molding sheath is formed, the process route is long, so that the optical cable is very easy to twist and misplace when being continuously fed, the optical cable is deformed in the forming process, or the impressed mark cannot be impressed at an accurate position. Due to the problems, the speed of the optical cable and the material thereof in the feeding preparation process needs to be strictly controlled, so that the preparation efficiency of the 8-shaped optical cable is greatly influenced, the preparation cost of the 8-shaped optical cable is increased, and the economical efficiency of the preparation and application of the 8-shaped optical cable is reduced.
