Copper-coated plastic wire production process and copper-coated plastic wire production line

Abstract

The invention discloses a structure of a copper-coated plastic wire which is used for transmitting radio frequency signals and serves as a coaxial cable inner conductor and a copper-coated plastic wire production process. The structure of the copper-coated plastic wire is a copper layer coated plastic wire. A copper layer and a plastic wire are bonded though hot melting glue. A production line designed according to the structure of the copper-coated plastic line comprises a copper belt material disk (1), a copper belt cleaning and brushing device (2), a plastic wire coil (3) for wrapping hot melting glue films, a wrapping device (4) for enabling copper belts to wrap plastic wires, an argon arc welding gun (5) for welding copper belt longitudinal seams, an induction heating coil (7) for heating wire bases, a wire drawing machine (8), a cooling groove (9), a blowing-drying machine (10) and a copper-coated plastic wire finished product winding rotary drum (11). The argon arc welding gun, the induction heating coil and a large disk of the wire drawing machine are sealed in a protection gas box. Argon is led into a protection gas inlet (6) to prevent high temperature copper layers from being oxidized. Power for transmitting all devices of the production line is driven by the wire drawing machine so as to enable motion speed of all portions of the whole production line to be identical.

Description

technical field [0001] The invention relates to a material for an inner conductor of a coaxial cable for transmitting radio frequency signals, in particular to an inner conductor of a copper-clad plastic wire that can improve performance and reduce production costs. Background technique [0002] At present, the inner conductor material of the coaxial cable for transmitting radio frequency signals is mainly a bimetal composite wire such as copper-clad aluminum or copper-clad steel. The wire diameter is generally less than 7.00mm. For copper-clad aluminum wires and copper-clad steel wires with thicker wire diameters, copper tubes are often used instead due to the difficulty in manufacturing. In order to make the copper tube have a certain rigidity and not deform after being bent, two measures are generally taken: one is to increase the thickness of the copper tube. Relevant standards stipulate that for copper tubes of φ7.00mm~φ13.1mm, the wall thickness is required to be 0.5...
