In the process of operation, the chrome plated cylinder barrel mainly refers to the rod end cover (cylinder head) of the hydraulic cylinder. The cylinder head can be made into a whole structure with the guide sleeve, or can be made into a split structure (cap), and can also be Whether the cylinder head and the cylinder, the piston rod and the guide sleeve are sealed and divided into a sealed cylinder head and a non-sealed cylinder head. The cylinder head and the cylinder barrel must have a reliable connection structure (including locking measures) and sufficient connection strength. It should be easy to disassemble.
The chrome-plated cylinder and cylinder head connection usually have flange connection, internal (outer) thread connection, inner (outer) key connection, tie rod connection, etc.; because the cylinder head is easy to disassemble, the cylinder head and hydraulic pressure are required. Cylinder cylinders usually do not use welded joints because of the different positions of the hydraulic cylinder ports on the cylinder head, which are divided into axial oil ports and radial oil ports.
What are the characteristics of chrome-plated cylinders?
1 sand bar abrasive load is small, sand bar is used for a long time.
2 speed is low, generally below 100mm/min.
The 3-cylinder cylinder should inject a large amount of cutting fluid during honing, which can wash away the detached abrasive grains, the processing surface is fully cooled, the workpiece heat is small, and the deformation layer is extremely thin, so that a good surface quality can be obtained.
4-cylinder honing generally obtains holes with an accuracy of IT6~17, Ra0.2~0.025m, and the shape error is generally less than 0.005mm.
