Problems solved by technology

[0002] At present, the existing metal pipe embossing is generally welded into a smooth round pipe by a forming die, and then the metal pipe is rolled by the embossing die under high-speed rotation to produce annular or spiral patterns. When there is manufacturing deviation and wear of equipment or molds, it will cause periodic defects in the cable, causing excessive voltage standing wave ratio (VSWR) peaks in the corresponding frequency band

Embodiment Construction

[0008] As shown in FIG. 1 , the present invention includes a main embossing tractor 3, a pay-off auxiliary tractor 4, a take-up auxiliary tractor 5, an embossing host 6, and a control system 7, which is characterized in that the control system 7 is connected to the embossing main tractor Machine 3, take-up auxiliary tractor 5, pay-off auxiliary tractor 4 and embossing host 6. The main pulling machine 3 pushes the outer conductor 2 forward in the direction F shown in the figure, while the cable core 1 is pulled forward by the outer conductor under the pay-off tension N of the pay-off auxiliary pulling. And under the work of the take-up tension P of the take-up auxiliary traction, the bellows rolling task is completed. Through the control system 7, a random and fluctuating signal within a certain range is given to the corrugated main traction machine, 3, the pay-off auxiliary traction 4, the wire take-up auxiliary traction 5, and the corrugated main machine 6, so that the speed ...

Abstract

The invention is concerned with the forming equipment for radio frequency communication cable metal rumple outer conductor, consists of the rolling-grain main traction machine, the drawing-line assistant traction machine, the rolling-gain mainframe, and the controlling system, the characteristic is: the controlling system connects with the rolling-grain main traction machine, the drawing-line assistant traction machine, the putting-line assistant traction machine and the rolling-gain mainframe. The advantages of the invention are: (1) reducing the voltage standing wave ratio of the product, the voltage standing wave ratio of the cable is below 1.08 when the frequency range is 5-3000MHz. (2) reduces the affects of the capability that creates by the drawbacks of the rolling-grain equipment or the mould.

Description

technical field [0001] The invention relates to a forming device for metal corrugated outer conductors of radio frequency communication cables. Background technique [0002] At present, the existing metal tube embossing is generally welded into a smooth round tube by a forming die, and then the metal tube is rolled by the embossing die under the condition of high-speed rotation, resulting in annular or spiral patterns. When the equipment or mold has manufacturing deviation and wear, it will cause periodic defects in the cable, which will cause excessive voltage standing wave ratio (VSWR) peaks in the corresponding frequency band. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a metal corrugated outer conductor forming device for radio frequency communication cable, which can effectively reduce the voltage standing wave ratio (VSWR) in production, and make the conductor corrugation equipm...
