Technical development of Seamless Honed Pipe Cold Drawn Tube

- Sep 03, 2020-

Introduced the use of plane strain theory, on the prestressed high rigidity full hydraulic cold drawing machine, through the special reduction of wall thickness tube drawing method, directly drawing the hydraulic pneumatic tube tube. The drawing force, reasonable wall reduction rate, cold drawing process and equipment characteristics during tube drawing are analyzed. It is proposed that comprehensive control of process system accuracy is the key to improving product quality. Practice shows that the cylinder tube made of high-precision cold-drawn steel tube has high strength and rigidity, good wear resistance, and has the characteristics of hard inner surface and tough outer surface. High-precision cold drawn cylinder tube is an ideal metal material for directly manufacturing various cylinders.
