Embodiment 1

[0017] Taking the pure copper outer conductor semi-rigid RF cable RG402 as an example, the specific process steps are as follows, see figure 1 ,

[0018] S1: First, install the pushed and qualified Φ2.98mm core wire on the pay-off frame, and adjust the pay-off tension to 10N for stable control of production. The core wire includes an inner conductor and an insulating layer;

[0019] S2: Put the pure copper strip with a width of 12mm and a thickness of 0.2mm on the strip rack, adjust the tension of the strip to 15N, and trim the copper strip. Turn on the laser welding machine for welding debugging. During the debugging process, ensure that the copper strips are trimmed neatly, without flashes or burrs. The output power of the machine is controlled at 1.05 ~ 1.35KW, and the debugging production speed is controlled at about 10m / min;

[0020] S3: After welding and debugging, insert the Φ2.98mm core wire into the pure copper strip for cladding, forming, welding and sizing. Among ...

Abstract

The invention relates to a processing process of a semi-steel cable outer conductor. A semi-steel cable comprises an inner conductor, an insulating layer and the outer conductor. The processing process comprises the following specific steps: S1, firstly, putting a pushed and certificated phi 2.98 mm core wire on a pay-off stand, adjusting laying tension as 10-20 N, wherein the core wire comprisesthe inner conductor and the insulating layer; S2, putting a metal tape with the width of 12 mm-14 mm and the thickness of 0.2 mm-0.4 mm on a tap putting rack, and adjusting the tap putting tension as15-30 N; carrying out metal tape trimming, wherein the width of the trimmed metal tape is 11-12 mm, then molding through a horn model, and opening a laser welder to carry out weld debugging; and S3, penetrating the core wire with the diameter phi of 2.98 mm into the metal tape, cladding, molding, welding and coining. The semi-steel cable manufactured by the processing process provided by the invention has the advantages of small radio frequency leakage and stable property. According to the invention, the quality stability, the production length and the manufacturing process can be greatly improved, the process loss is greatly reduced, and the manufacturing cost is effectively reduced.

Description

(1) Technical field [0001] The invention relates to a cable manufacturing process, in particular to a process for processing the outer conductor of a semi-rigid cable. (2) Background technology [0002] With the development of my country's communication industry, the frequency of cable transmission is becoming more and more high-frequency, accompanied by semi-rigid cables such as RG402 and RG405, which are increasingly used as high-frequency and ultra-high-frequency cables for microwave, In radio equipment such as radio frequency. However, there has always been a technical bottleneck in the manufacture of this cable, because the outer conductor is formed by manually inserting the core wire into the outer copper tube. The processing method is primitive, which leads to the inability to produce continuous and large lengths, especially the single length, which has always troubled the manufacturers. At the same time, there are also problems such as unstable product quality, low ...
