Abstract

The invention discloses a process for manufacturing an outer conductor in a coaxial cable production process. The outer conductor consists of an aluminum foil shielding layer and a woven layer. The process for manufacturing the outer conductor comprises the following steps of: (1) longitudinally wrapping and oiling an aluminum foil: feeding the aluminum foil to a lubricating oil device through an aluminum foil breakage alarm after the aluminum foil in an aluminum foil payoff reel is horizontally released, oiling the aluminum foil, discharging the aluminum foil coated with the lubricating oil from the lubricating oil device, leading out the aluminum foil through a guide wheel, and gradually longitudinally wrapping the aluminum foil on a prepared core wire; and (2) weaving an alloy wire. The friction between the aluminum foil coated with the lubricating oil and the alloy wire is weakened and eliminated, abrasion of the aluminum foil and the alloy wire is reduced, and stability of product performance is ensured. Meanwhile, the probabilities of aluminum foil breakage and alloy wire breakage are reduced, shutdown in the production is reduced, and the production efficiency is greatly increased.

Description

(1) Technical field [0001] The invention relates to a manufacturing process of an outer conductor in the production process of a coaxial cable and a special lubricating oil device thereof. (2) Background technology [0002] With the development of communication technology and the improvement of people's living standards, higher and higher requirements are put forward for the performance of coaxial cables. In the coaxial cable structure, the outer conductor adopts the structure of aluminum foil longitudinal wrapping and alloy wire braiding in many cases, which is completed on the braiding machine in the braiding process at one time. This brings up two questions: [0003] (1) During weaving, due to high-speed production, there must be continuous friction between the aluminum foil and the alloy wire, which will cause the metal layer on the surface of the aluminum foil to wear and affect the shielding performance of the product. This intensification of wear also increases the ...
