Drawing process of metal hose for preparing optical fiber cable

Abstract

The invention discloses a wire drawing process for preparing metal hoses for optical fiber cables, which comprises the following steps: first cleaning the metal wire blanks once, pickling once, neutralizing once, and cleaning twice, and scrubbing oxide impurities on the surface of the metal wire blanks ; Add the metal wire blank, clarifying agent, sulfate, and silicon fluoride into the melting furnace, heat the melting furnace so that the temperature of the metal wire blank rises, preheat it first, and then melt it to form a molten metal; use a wire drawing machine to melt the metal The metal wire is drawn once to form a metal wire; the drawn metal wire is cooled by water, pickled twice, neutralized twice, cleaned three times, and the wire drawing oil is sprayed on the surface of the metal wire and then put into the wire drawing machine for second drawing. Metal wire and made into metal hose. The invention has the advantages of simple steps, strong metal wire drawing, strong flexibility, flexibility, strong bending and vibration resistance, strong pressure bearing capacity, and good corrosion resistance. At the same time, it has strong metal texture, beautiful outer surface, and gloss retention. Long color retention time.

Description

technical field [0001] The invention relates to a wire drawing process, in particular to a wire drawing process for preparing metal hoses for optical fiber cables. Background technique [0002] Metal hose is an important part of the connecting pipeline of modern industrial equipment. In complex pipeline systems, due to the limitation of space and location conditions, various difficulties in installation work are often caused: the formed pipe cannot be installed; Conversely, a makeshift tube will inevitably produce localized cold corrections. Depending on the diameter of the pipe and the specific conditions on site, the amount of cold correction ranges from a few millimeters to tens of millimeters, and some reach hundreds of millimeters. Practice has proved that the larger the amount, the higher the internal stress, and the installation stress remaining in the piping system is undoubtedly extremely hidden. In the prior art, the metal hose is made of metal wire, and the prod...

Problems solved by technology

In the prior art, the metal hose is made of metal wire, and the production process of the metal itself is very complicated when it is drawn into a wire, and the wire drawing process is very easy to break. At the same time, in order to improve the performance of the metal wire, the aesthetic treatment of its surface is also necessary
