Embodiment 1

[0024] Taking the copper-aluminum composite board with a copper layer thickness of 0.2mm and an aluminum layer thickness of 0.46mm as an example, it is explained in figure 1 The method for producing copper-clad aluminum tubes with an outer diameter of φ13.1mm on the production line shown.

[0025] 1. Prepare copper-aluminum composite strip: In order to obtain a copper-clad aluminum tube with an outer diameter of φ13.1mm after the clad and welded copper-clad aluminum tube billet is drawn with a section reduction rate of about 25%, the cutting When cutting the width of the copper-aluminum composite strip, it should be calculated according to φ15.1mm. The blanking width is 47.4mm.

[0026] 2. The cut copper-aluminum composite strip is placed on the tray 1 with the aluminum layer facing up and the copper layer facing down.

[0027] 3. When the copper-aluminum composite strip passes through the groove cutting device 2, after the two ends of the aluminum layer are cut out of the 4...

Abstract

The invention relates to a structure, production method and production line of a copper-clad aluminum pipe of a coaxial cable inner conductor for transmitting radio-frequency signals. The copper-clad aluminum pipe is rolled into a round pipe with a copper aluminum composite belt, a longitudinal joint of a copper layer is welded by argon-arc welding, an aluminum layer adjoining plane is pressed by drawing, and metallurgical bonding is formed by means of atomic diffusion in the annealing process. The copper-clad aluminum pipe production line is composed of a copper aluminum composite belt material plate (1), an aluminum layer two-end planing cutting groove device (2), a copper-clad aluminum pipe forming device (3), an argon arc welding machine (4), a welding gun (5), a wire drawing die (6), a wire drawing machine (7), a drawing large plate (8) and a pipe blank wire-collecting device (9) and the like. Power transmitted by each device process of the production line is all driven by the wire drawing machine, so that the moving speeds of the processes of each part of the whole production line are consistent.

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 a copper-clad aluminum tube inner conductor which 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 pipes of φ7.00mm~φ13.1mm, the wall thickness is required to be 0.50mm~...
