A production process for slotting an outer conductor of a leaky cable

Abstract

The invention provides a production process for slotting an outer conductor of a leaky cable, which comprises a metal strip slotting production line, a metal strip longitudinal wrapping production line and a sheathing production line, thereby saving the operation and storage of raw materials and avoiding waste or pollution in the operation and storage process, and production is efficient and reliable. After the production of the semi-finished product output from the leakage cable insulation process is completed, A corresponding slot hole is laser cut on the metal belt according to a specific slot parameter by using a numerical control laser cutting device, A slotted out conductor is produced, Then the slotted metal strip is directly covered on the insulation through the outer conductor longitudinal cladding molding die, and finally the sheath production is directly completed by the sheath extruder to produce the finished cable leakage, so that the outer conductor of the leakage cable is punched from the raw material to the raw material, and the outer sheath after the longitudinal cladding molding and the outer conductor molding is completed at one time.

Description

technical field [0001] The invention relates to the technical field of making leaky cables, in particular to a production process for slotting outer conductors of leaky cables. Background technique [0002] Leaky coaxial cable is a special type of radio frequency coaxial cable. The special feature is that a series of slots need to be made on the outer conductor that acts as a shield, so that the electromagnetic energy transmitted inside the leaky cable can pass through the slots. The hole leaks radiation outward, and the electromagnetic energy in the external environment of the leaky cable can be coupled and absorbed inward through the slot hole to complete the signal interaction between the leaky cable and the external environment, and to meet the requirement of mobile communication along the line (along the laying direction of the leaky cable). signal request. [0003] Leaky coaxial cables can be divided into coupling type leaky cables and radiation type leaky cables acco...

Problems solved by technology

[0004] 1 Raw materials are operated in different processes in each workshop, and storage takes up too much time and space, and is easily affected by environmental pollution and affects the quality of use. At the same time, the separate thin copper strip punching process in the outer conductor process needs to reserve operating areas and equipment Area, occupying a large space;

[0005] 2. In the outer conductor process, the separate process of punching thin copper strips needs to match the product quantity with the finished product process, resulting in a larger production quantity of the outer conductor than the latter process. Excessive production leads to more waste of materials in the final process;

[0006] 3 The slotted thin copper strip used for the outer conductor produced by the punching machine, due to the problem of equipment technology, the precision fluctuates greatly;

[0007] 4. Using a punching machine to produce slotted thin copper strips for outer conductors requires the use of stamping dies, and each die can only be used for one slotting structure. The cost of the die is high. When changing the slotting structure, the die needs to be replaced, which cannot be flexibly produced and cannot meet the requirements. Create multiple groups of slotted structures in a continuous leaky cable;

[0008] 5 To use a punching machine to produce slotted thin copper strips for outer conductors, it is necessary to pre-open molds for different groove types, and in order to ensure the stamping quality and service life of the molds, the mold processing is complicated and the mold opening takes a long time
