2.Product Details:
(1) Honed tube: The quilted pipe is a kind of high-precision steel pipe material processed by cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer walls of the precision steel tube, no leakage under high pressure, high precision, high finish, no deformation in cold bending, no flaring, no cracks in flattening, etc., it is mainly used to produce products for pneumatic or hydraulic components, such as cylinders or Cylinder, can be seamless pipe. The chemical composition of the quilted grinding tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.
(2)Characteristic:
High precision and small batch production
The cold drawn finished product has high precision and good surface quality.
The cross-sectional area of the steel pipe is more complicated.
The performance of the steel pipe is better, and the metal is denser
(3)Processing technology:
The quilted tube is processed by rolling, because the surface layer has residual compressive stress on the surface, which helps to close the tiny cracks on the surface and hinders the expansion of erosion. Therefore, the corrosion resistance of the surface can be improved, and the generation or expansion of fatigue cracks can be delayed, thereby improving the fatigue strength of the quilted mill. Through rolling forming, a layer of cold work hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the quilting tube and avoiding burns caused by grinding. . After rolling, the reduction of surface roughness value can improve the fit properties.
(4)The principle of rolling processing: it is a pressure finishing process, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to apply a certain pressure to the surface of the workpiece, so that the metal on the surface of the workpiece produces plastic flow and fills the original residue. In the low concave trough, the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface structure is cold hardened and the grains are thinned, forming a dense fibrous shape, and forming a residual stress layer, which improves the hardness and strength, thereby improving the wear resistance and corrosion resistance of the workpiece surface. Rolling is a non-cutting plastic processing method.
