Following device of copper tube inner conductors for radio frequency coaxial cable and following method thereof

Abstract

The invention relates to a following device of copper tube inner conductors for a radio frequency coaxial cable and a following method thereof, in particular to the device for realizing continuous production of the smooth copper tube inner conductors in production of the radio frequency coaxial cable and the following method thereof. The conductor following device comprises copper tube fixtures, a sliding plate unit, a guide rail, a support and a welding torch, wherein, the sliding plate unit is equipped with a sliding plate 1 and a sliding plate 2 which are provided with two groups of the copper tube fixtures respectively; each copper tube fixture comprises a static fixture, a movable fixture, a push rod, a push rod support, a connection rod and a handle; and the welding torch is arranged on the support. The following method comprises the following steps: (1) polishing end surfaces of the two copper tube inner conductors needing welding with a file; (2) clamping the two polished copper tube inner conductors needing welding on the copper tube fixtures respectively; (3) pushing the sliding plates so that end parts of the two copper tube inner conductors get close to each other, putting lined copper tubes on the end parts of the two copper tube inner conductors, and indirectly or directly placing brazing filler metal; and (4) welding with the welding torch by a flame heating method to finally obtain soldered joints of the copper tube inner conductors after condensation.

Description

technical field [0001] The present invention relates to a radio frequency coaxial cable brass tube inner conductor connecting device and a connecting method thereof, which relate to a device and a connecting method for realizing continuous production of a smooth copper tube inner conductor during radio frequency coaxial cable production. In particular, it relates to a splicing device and splicing method for an inner conductor of a copper tube of a radio frequency coaxial cable, which reduces costs and improves production efficiency. Background technique [0002] The inner conductor of the smooth copper tube used in the production of radio frequency coaxial cables, the purchased smooth copper tube has a certain length. After the production of a coil of copper tubes, the copper tube can only be replaced by parking, which leads to failure to meet customer requirements. The section is long, the parking wastes time, and because the RF coaxial cable usually adopts the physical foa...

[0002] The inner conductor of the smooth copper tube used in the production of radio frequency coaxial cables, the purchased smooth copper tube has a certain length. After the production of a coil of copper tubes, the copper tube can only be replaced by parking, which leads to failure to meet customer requirements. The section is long, the parking wastes time, and because the RF coaxial cable usually adopts the physical foaming process, 3-4KG of raw materials are wasted every time when the copper pipe is replaced by parking
