The processing of the honing pipe is rolling, and the surface of the steel pipe is under pressure. It has a good sealing effect on small surface cracks and can prevent the surface from being corroded. Therefore, the corrosion resistance of the surface can be improved, the generation and expansion of cracks can be reduced, and the compressive strength of the honing pipe can be improved.
The honing tube is formed by roll forming to form a cold working hardened layer on the surface to reduce the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving wear resistance and avoiding burns caused by grinding. The surface roughness after rolling is greatly reduced, which improves the compatibility of the ground pipe. To
The so-called rolling process of the honing tube is a chipless machining. At room temperature, the plastic deformation of metal is used to smooth the surface roughness, so as to achieve the ultimate goal of changing the surface structure, mechanical properties, performance and size. This kind of rolling processing technology can not achieve grinding processing, while meeting the requirements of finishing and strengthening.
The principle of the honing pipe pressing process is to use the cold plastic properties of metal at room temperature and apply a certain pressure on the workpiece with a rolling tool to cause the metal on the metal surface to produce plastic flow, thereby reducing the surface roughness of the workpiece. Due to the plastic deformation of the pressed surface metal, the surface structure is cold hardened and refined to form a dense fiber shape, which improves the hardness and strength of the metal, and improves the wear resistance, corrosion resistance and coordination of the surface.
