Hydraulic cylinder mainly by the cylinder, piston rod, piston, cylinder head, cylinder end, seals, accessories and other components, including cylinder, piston, piston cylinder called Big Three. Hydraulic cylinder is the hydraulic energy into mechanical energy, do reciprocating motion (or swing movement) of the hydraulic actuators; simple cylinder structure, reliable operation; its good quality and low price fuel tank, designed large tonnage cylinders, easy to operate. Three main factors affecting the quality of the hydraulic cylinder: 1, the design of hydraulic cylinders (cylinder) experience 2, hydraulic cylinders (cylinder) 3 processing quality, use and maintenance of hydraulic cylinders (cylinder) case the fuel tank is the most important parts of construction machinery, traditional Processing methods are: Broaching cylinder - fine boring cylinder - grinding cylinder. Using the rolling method is: Broaching cylinder - fine boring cylinder - rolling cylinder, the step is part of the project 3 cylinders, but the contrast on time: grinding cylinder one meter in about 1-2 days, rolling cylinder about 1 m in 10-30 minutes. Investment Contrast: quilting grinder or mill (tens of thousands - hundreds of millions), rolling knife (1 thousand - tens of thousands). After rolling, the surface roughness of the hole before rolling Ra3.2 ~ 6.3um buildings reduced to Ra0.4 ~ 0.8 & um hollow cylinder, the surface hardness of the hole by about 30%, the cylinder surface fatigue strength increased by 25%. Cylinder life if only to consider the impact of the cylinder barrel, increased by 2 to 3 times, boring rolling process more grinding efficiency is about 3 times. The above data shows that the rolling process is efficient and can greatly improve the surface quality of the cylinder barrel.
