一种漏缆外导体开槽的生产工艺
CROSS REFERENCE TO RELATED APPLICATIONS
本发明涉及漏缆制作的技术领域，具体为一种漏缆外导体开槽的生产工艺。
The present disclosure relates to the field of leaky cable production technologies, and more particularly, to a production process for slotting an outer conductor of a leaky cable.
漏泄同轴电缆是一类特殊的射频同轴电缆，特殊之处在于需在其起屏蔽作用的外导体上开制一系列槽孔，使得在漏缆内部传输的电磁能量能经开制的槽孔向外漏泄辐射，在漏缆外部环境中的电磁能量能经槽孔向内耦合吸收，以完成漏缆与外部环境之间的信号交互，满足沿线(沿漏缆敷设方向)移动通信对电磁信号的要求。
A leaky coaxial cable is a special radio frequency coaxial cable, characterized in a series of slot holes arranged in an outer conductor of the leaky coaxial cable that plays a role of shielding, so that electromagnetic energy transmitted inside the leaky coaxial cable can leak out and radiate through the slot holes, and electromagnetic energy in an external environment of the leaky coaxial cable can be inwardly coupled and absorbed through the slot holes to allow signal interaction between the leaky coaxial cable and the external environment, satisfying the requirements of mobile communication along a cable (along a laying direction of the leaky coaxial cable) on electromagnetic signals.
漏泄同轴电缆按其辐射特性可分为耦合型漏缆和辐射型漏缆两大类，其中辐射型漏缆外导体上开制的槽孔为薄铜带经冲压冲床冲孔生产，本发明叙述的生产工艺主要适用于辐射型漏缆。
According to the radiation characteristics, the leaky coaxial cables may be divided into two categories: coupling leaky cables and radiating leaky cables, wherein slot holes arranged in an outer conductor of a radiating leaky cable are made of a thin copper strap punched by a punching press, and the production process described in the present disclosure is mainly suitable for the radiating leaky cable.
辐射型漏泄同轴电缆的生产，需要经过内导体、绝缘、外导体、护套四个工序。
The production of the radiating leaky cable needs to go through four processes corresponding to an inner conductor, an insulator, an outer conductor and a sheath.
其中外导体工序又需经薄铜带冲孔和薄铜带纵包两个工序，其中薄铜带冲孔工序一般单独进行，使用冲床冲压薄铜带生产，需按特定槽孔设计指定冲压模具，输出为成卷的已开槽薄铜带；薄铜带纵包工序使用的原材料为已开槽薄铜带，是经冲床冲压好特定槽孔的薄铜带，具体为将开制好槽孔的薄铜带纵包在漏缆的绝缘上，是一个单独的工序，但由于其输出的性能不受护套工序影响，为了缩短生产周期，提升产品合格率，一般与护套工序同时进行，即纵包完成后直接进入到护套工序，护套完成即完成漏缆成品的生产。
In the thin copper strap punching process generally carried out separately, the thin copper strap is punched by the punching press, a designated punching mould needs to be designed according to specific slot holes, and the rolled and slotted thin copper strap is outputted.
但是由于外导体生产工艺中的两个顺序过程，即先薄铜带冲孔、后薄铜带纵包，故其一般分离生产，这将导致：
However, due to two sequential processes in the production process of the outer conductor, i.e., the thin copper strap punching and then the thin copper strap longitudinal coating, the outer conductor is generally produced separately, which will lead to that:
1原材料在各车间不同工序上运转，贮存占用过多的时间、空间，而且容易受到环境的污染而影响使用品质，同时外导体工序中单独的薄铜带冲孔工序需要预留运转区域和设备区域，占地空间较大；
1. the raw material is operated in different processes in each workshop, which takes up too much time and space for storage and is easy to be polluted by the environment, thus affecting the use quality, and meanwhile, the separate thin copper strap punching process in the outer conductor process needs to reserve an operation area and a device area, thus occupying a large space;
2外导体工序中薄铜带冲孔单独工序需要与成品工序匹配产品数量，导致外导体生产数量需要比后一道工序数量更多，过多的生产导致最后工序材料存在较多浪费；
2. the separate thin copper strap punching process in the outer conductor process needs to match with a finished product process in product quantity, resulting in that the production quantity of the outer conductor needs to be more than the quantity of next process, and excessive production results in more waste of materials in the final process;
3冲床生产外导体用开槽薄铜带，由于设备工艺问题，精度浮动较大；
3. the slotted thin copper strap for the outer conductor is produced by the punching press with large precision fluctuation due to device and process problems;
4使用冲床生产外导体用开槽薄铜带，需使用冲压模具，且每一个模具只能适用一种开槽结构，模具成本高，变更开槽结构时需要更换模具，不能灵活生产，无法满足在一根连续漏缆中开制多组开槽结构；
4. the slotted thin copper strap for the outer conductor is produced by the punching press with a punching mould, for which one punching mould can only be suitable for one slotted structure, resulting in high cost of the mould; and when the slotted structure is varied, the mould needs to be replaced, so flexible production is not possible, and multiple groups of slotted structures cannot be arranged in one continuous leaky cable; and
5使用冲床生产外导体用开槽薄铜带，需针对不同槽型预先开模，且为保证模具的冲压质量和使用寿命，模具加工复杂，开模耗时长。
5. the slotted thin copper strap for the outer conductor is produced by the punching press, which needs to open the mould in advance according to different slot types, therefore in order to ensure the punching quality and service life of the mould, the processing of the mould is complicated and the time for opening the mould is long.
