What is the difference between cylinder tube and rolled tube?
The material of the cylinder tube is mainly hot-rolled seamless steel pipe, which is made by boring and rolling combined cutting process. With the development of my country's industry, the old process of producing hydraulic cylinders has been difficult to meet the needs of production development. The cylinder tube is a new type of energy-saving product.
Rolled tubeIt refers to steel pipes with strict inner and outer diameter dimensional accuracy (tolerance range), good inner and outer surface finish, roundness, and straightness, and uniform wall thickness. After slight honing, this product can be directly used as hydraulic and pneumatic cylinder block tubes, which is of great significance to saving energy and reducing investment in hydraulic cylinder and cylinder processing equipment. The rolling method is: broaching cylinder block - fine boring cylinder block - rolling cylinder block, the process is three parts. After rolling, the surface roughness of the hole is reduced from Ra3.2~6.3um before rolling to Ra0.4~0.8um, the surface hardness of the hole is increased by about 30%, and the fatigue strength of the inner surface of the quilted tube is increased by 25%.
