How does a hydraulic cylinder work?
The working principle of a hydraulic cylinder is: Speaking of its working principle, I will first talk about its five most basic components, 1-cylinder barrel and cylinder head 2-piston and piston rod 3-sealing device 4-buffer device 5-exhaust device. The work of each type of cylinder is almost the same. Take a manual jack as an example of its working principle. The jack is actually the simplest oil cylinder.
Hydraulic cylinder barrel processing belongs to the category of deep hole processing. Ready-made steel pipes can be used. After welding, heat treatment should be performed first to ensure that the material meets the required mechanical properties. Deep hole processing equipment must be used during processing. During finishing, leave a grinding allowance and drill the inner hole to size on a deep hole grinding machine. Generally, oil cylinder processing plants do not re-cold draw steel pipes and mainly purchase ready-made pipes. If it is a small oil cylinder, if tie rods are used to fix the cylinder head at both ends, and there is no requirement for material hardness, steel pipes can be used for direct processing and grinding.
Generally, the outer diameter does not need to be reprocessed. If it needs to be processed, there is no need for tolerances, and the roughness requirements are not high.
