Pneumatic cylinder tube description

Cylinder tube is a kind of high precision steel tube material after cold drawing or hot rolling. Because there is no oxide layer on the inner and outer walls of precision steel pipe, no leakage under high pressure, high precision, high finish, cold bending without deformation, flaring, flattening without cracks and so on, it is mainly used for the production of pneumatic or hydraulic components, such as cylinder or cylinder, can be seamless pipe. The chemical composition of the cylinder tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.

Pneumatic cylinder tube processing technic

The cylinder tube is processed by rolling. Because the surface layer has surface residual compressive stress, it is helpful to seal the small cracks on the surface and prevent the expansion of erosion. Thus improving the surface corrosion resistance, and can delay the generation or expansion of fatigue cracks, thus improving the cylinder pipe fatigue strength. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thus improving the wear resistance of the inner wall of the cylinder tube and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness can improve the fit property.
Rolling machining is a kind of chip free machining. At normal temperature, the plastic deformation of metal is used to flatten the microscopic roughness of the workpiece surface so as to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of polishing and strengthening at the same time, which is unable to do grinding.
