Abstract

The invention discloses a process for preparing a metal wire drawing hose for aerospace. The process comprises the following steps that a metal wire material is subjected to surface treatment, water cleaning, neutralization and drying sequentially; at the same time, wire drawing oil raw materials are prepared, wire drawing oil is prepared, the prepared wire drawing oil is added onto the surface of the dried metal wire material in a wire drawing machine, wire drawing is conducted, and a metal wire is formed; and finally the obtained metal wire is subjected to a primer spraying procedure, an intermediate coat spraying procedure and a finishing coat spraying procedure, and the metal hose is obtained. The process is simple in step, wire drawing of the metal wire is firm, the metal wire has the advantages of being high in toughness, scalability, bending resistance, shock resistance and bearing ability and good in corrosion resistance, meanwhile, the metal texture feeling is high, the outer surface is beautiful, and light keeping and color keeping time is long.

Description

technical field [0001] The invention relates to a wire drawing process, in particular to a process for preparing metal wire drawing hoses for aerospace. 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 production proc...
