What are the technical requirements for cylinder tube processing?

date: 2021-11-04name:Foshan weiyingjia Technology Co., Ltdhits:648

The processing technology requirements for cylinder tubes are mainly processed by cold drawing and hot rolling. It is a high-precision steel pipe material, because there is no oxide layer on the inner and outer walls of the precision steel pipe. It bears high pressure and no leakage. It not only has very high precision, but also has high finish. Even if it is cold bending, there will be no deformation and flaring, There is no crack when flattening, so it is mainly used in hydraulic components and pneumatic products, such as oil cylinder and air cylinder.

Because the cylinder tube adopts the rolling forming technology, more compressive stress will remain on its surface, but it will help to close the small cracks on the surface and effectively prevent the expansion of erosion. Finally, the corrosion resistance of the cylinder tube on the surface is improved, which can effectively prolong the expansion and extension of fatigue, and the fatigue of the cylinder tube has been significantly improved. After the cylinder tube is formed by rolling, a hardened layer will appear on the surface of the cylinder tube due to the effect of rolling, which reduces the contact surface of the grinding pair, including plastic deformation and elastic deformation, effectively improves the wear resistance on the inner wall of the cylinder tube, and also avoids the burn caused by grinding. After rolling, The surface roughness of the cylinder tube will be greatly reduced.

As the rolling processing belongs to non cutting processing technology, which is mainly small at room temperature and uses the principle of metal plastic deformation to promote the micro unevenness of the surface of the workpiece to be rolled flat, so the structure and mechanical properties of the surface layer are effectively changed. Therefore, this processing method effectively improves the purpose of finishing processing and strengthening, And grinding can't be done at all.
