一种漏缆外导体幵槽的生产工艺 技术领域
[0001] 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。

[0003] 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。 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。 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。 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：
[0004] 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；
[0005] 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；
[0006] 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；
[0007] 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；
[0008] 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。
