The honing pipe is a kind of high-precision pipe in the process of operation, and it is widely used in various industries. In order to ensure the normal performance of the performance, the accuracy should reach the corresponding standard. For example, the inner hole precision of the honing pipe should reach H7-H10, that is, the inner hole roughness should be less than 0.63nm, and the standard straightness is also limited by corresponding data, generally less than 0.3mm/m to meet the production needs.
The hydraulic cylinder cylinder is the main body of the honing pipe. The inner hole is generally manufactured by precision machining such as boring, reaming, rolling or honing, so that the piston and its seals and supports can smoothly slide and reduce wear and tear. The cylinder is subjected to a large hydraulic pressure and, therefore, should have sufficient strength and rigidity.
The end caps form a closed oil chamber with the cylinder barrel at both ends of the cylinder barrel. Therefore, the end cap and its connecting parts should have sufficient strength. The design must consider both the strength and the structural form with better craftsmanship. The guide sleeve guides and supports the piston or the plunger. Some hydraulic cylinders do not have a guide sleeve and are directly guided by the end cover hole. This structure is simple.
Main application of honing tube
A honing pipe is a high-precision steel pipe material that has been treated by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipes have no oxide layer, high pressure and no leakage, high precision, high smoothness, no deformation of cold bending, flaring, flattening and cracking, etc., they are mainly used to produce pneumatic or hydraulic components, such as cylinders or The cylinder can be a seamless tube. The chemical components of the honing pipe are carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.
