Manufacturing process of high precision cold drawn tube
High-precision cold-drawn tube is a high-precision seamless steel tube produced by cold-rolling, cold-drawing or a combination of cold-rolling and cold-drawing. It has the characteristics of high dimensional accuracy and good surface finish. Let’s introduce the manufacturing process of high-precision cold-drawn tubes:
(1) Pipe material supply, the pipe materials used are hot-rolled finished pipes or semi-finished pipes, extruded pipes and welded pipes.
(2) Pipe material preparation, including inspection, bundling, pickling, cleaning, rinsing, neutralization, drying, lubricating, etc.
(3) Cold rolling or cold drawing;
(4) Finishing of finished products includes heat treatment of finished products, straightening, sampling, cutting head and tail, inspection, hydraulic test, oiling, packaging, storage, etc. Different products have different finishing contents.
High-precision cold-drawn steel pipe is an ideal metal material for various hydraulic cylinder tube. The cylinder tube is the main part of a hydraulic cylinder barrel. The hydraulic cylinder tube made of high-precision cold-drawn steel tube has high strength, rigidity, good wear resistance and good performance, and the inner surface is hard and the outer surface is tough.
High-precision cold-drawn pipes also can be used in hydraulic system piping, automobile manufacturing piping, military industry, construction machinery, railway locomotives, aerospace, ships, injection molding machines, die-casting machines, machine tools, diesel engines, petrochemicals, power plants, boiler equipment and other industries .
