Embodiment 1
[0028] Such as figure 1 The shown method for manufacturing the seamless airtight aluminum tube of the present invention for manufacturing the optical fiber composite ground wire optical unit comprises the following steps:
[0029] (1) Chamber heating, firstly heat the chamber to about 500°C,
[0030] (2) Feed in the aluminum rods, send two aluminum rods into the extrusion wheel, two grooves are opened on the outer surface of the extrusion wheel along the circumferential direction, and one aluminum rod blank can be fed in each. The extrusion wheel rotates clockwise to feed the billet into the cavity,
[0031] (3) Extruded aluminum tube, when the billet reaches the mouth of the cavity, there are two raised stops in the cavity corresponding to the grooves of the extrusion wheel, which block the continuous movement of the billet along the circumferential direction. As a result, there is friction between the groove wall of the rotating extrusion wheel and the blocked aluminum rod...

The invention discloses a method for manufacturing a seamless airtight aluminum pipe optical unit of an optical fiber composite frame ground wire optical unit. The method comprises the following steps: aluminum rod blanks are sent into a cavity of a heated hot extrusion die, and the aluminum rod blanks create friction with a baffle block in the cavity; under the effect of friction, an aluminum rod is subjected to temperature rising and is plastically deformed, and then the deformed aluminum rod enters a coated mold cavity along an upward runner, is extruded from an annular gap between concave and convex dies, and is arranged on the outer layer of the optical unit penetrating through the dies in a sleeving manner to form the aluminum pipe optical unit; the aluminum pipe optical unit is cooled, pulled and cleaned, and finally, the processed aluminum pipe optical unit is wound to form a disc. According to the aluminum pipe optical unit manufactured by the method, the product performance is improved, welding is not needed, the surface of an aluminum pipe is seamless, and the aluminum pipe is high in airtightness and good in surface tensile strength and surface anti-seepage effect. The whole manufacture process of the aluminum pipe optical units and the manufacture process of overhead ground wires are environmentally friendly, no ultraviolet and infrared radiation generated by argon arc welding exists, and no ozone is produced. The manufacturing method has the advantages of cost saving, environmental protection and energy conservation.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to the technical field of optical fiber composite overhead ground wire manufacturing, in particular to a seamless airtight aluminum tube optical unit and a manufacturing method thereof. Background technique [0002] The aluminum tube optical unit has the advantages of corrosion resistance and increased short-circuit current capacity. The optical fiber composite overhead ground wire using this optical unit has excellent performance, greatly improving the safety and economic performance of the product, and is more and more recognized by users. . [0003] The traditional aluminum tube manufacturing process is to use aluminum strips of a certain width and thickness, and use argon arc welding to weld the aluminum strips to form aluminum tubes. However, there are many shortcomings in the existing aluminum tube manufacturing process, mainly including: 1. Using argon arc welding The ...
