Multi-core superfine coaxial cable CT connecting line cabling process

Abstract

The invention discloses a multi-core superfine coaxial cable CT connecting line cabling process. The process comprises the following steps that: static disc uncoiling is used for a core wire, and S-direction or Z-direction torque is generated by the core wire during uncoiling; the core wire enters a paper packing machine and a single twisting machine in turn after the uncoiling, enters an arch belt to be twisted and then enters a wire coiling shaft for cabling after the twisting is finished; the rotation of the torque in the reverse direction is generated when the arch belt is uncoiled towards the core wire, and the twisting torque is equal to the cabling pitch of the core wire; when the cabling pitch is controlled to be between 100 and 120 mm, the back-twist of the core wire of a coaxial cable is realized during cabling; and the wire coiling shaft does not rotate during cabling, and the arch belt rotates to realize the cabling of the coaxial cable on the wire coiling shaft. In the process, the static disc uncoiling is used and the wire coiling shaft does not rotate generally, and the arch belt rotates towards the reverse direction of the uncoiling torque, so that the uncoiling torque is counteracted with the cabling torque to realize the basic back-twist of the core wire, a technology for finishing the twisting cabling of a 128-core coaxial cable on an ordinary single twisting machine is realized, and expensive special back-twist equipment is not required to be provided in the production process.

Description

[0001] technical field [0002] The invention relates to the technical field of wire and cable production equipment, in particular to a CT connection wire forming process of multi-core ultra-thin coaxial cables. [0003] Background technique [0004] A color CT machine needs to transmit a large amount of signals when it is working, which cannot be borne by ordinary communication lines. At present, the color CT data connection lines are basically controlled by foreign manufacturers, and the domestic related production equipment and processes cannot meet the requirements for manufacturing color CT data connection lines. For example, for the stranding process of a 128-core coaxial cable, due to the large number of core wires in the 128-core coaxial cable, the current cabling methods cannot solve the problem of twisting back. Advanced back-twisting methods and equipment, such as applying a power to the pay-off reel to make it reversely rotate in the direction of strand rotatio...

AI Technical Summary

Problems solved by technology

Such ordinary untwisting methods or equipment can still achieve a certain untwisting effect on low-core coaxial cables, but it is powerless for 128-core coaxial cables. Usually, in order to achieve high-core coaxial cables , it is necessary to design special untwisting equipment. The untwisting equipment, together with the pay-off machine, wrapping machine and twisting machine, constitutes a special cable-forming equipment. The structure of this special untwisting equipment is extremely complicated, and the design is quite difficult. It is also quite expensive, which limits the development of domestic color CT data connection line production technology
