High precision cold-drawn steel tube technology and its application
High precision cold drawn steel pipe is a new type of high-tech energy-saving product. In recent years, the technology used in the production of precision steel pipes has been widely used in the domestic hydraulic, pressure cylinder, coal mine support (pillar), oil pump pipe, Jack and other manufacturing fields. The high precision cold drawn precision steel pipe is important to popularize the use of saving steel, improving machining efficiency, saving energy, and reducing investment in hydraulic cylinder and cylinder processing equipment. Cold drawing method: producing high-precision cold drawn pipe, compared with traditional cutting technology, the hydraulic cylinder has the following characteristics: (1) the production efficiency is high: the traditional production method of the cylinder with an inner diameter of 420 millimeters and a length of 12 meters is 154 hours, and the cold drawing process takes only 4 minutes. (2) high positive rate: rolling head boring, play a ...
