WHAT MATERIAL IS USED FOR THE CYLINDER BARREL?

图片
  As the main component of the hydraulic cylinder, the processing quality of the   cylinder barrel  directly affects the life and reliability of the entire product. The cylinder has high processing requirements, and its inner surface roughness is required to be Ra0.4 ~ 0.8um, and the requirements for coaxiality and wear resistance are strict. Generally, it is processed and produced by the principle of  honing  or rolling. The common materials of cylinder barrel are SAE1020, 1026, 1045,  ST52 seamless honed tubes , the steel tube is honed or rolled to meet the roughness requirement within 0.4μm. The low-pressure oil cylinder can use 1020 steel pipe, and the high-pressure oil cylinder can use CK45 steel pipe. As a professional cylinder barrel supplier, manufacturer,exporter in China,  Wuxi YUTONG  has more than 20 years production experience, we sell hydraulic honed tubing to customers and provide full range of technical support. Imperial sizes...

The heat treatments for Seamless Steel Tube For Hydraulic Cylinder Barrel

图片
  Most of the hydraulic cylinder is composed of a cylinder, cylinder head, piston and  piston rod  and sealing device. The comprehensive performance of the cylinder such as pressure resistance, wear-resistance and fatigue strength, determines the service life of the hydraulic cylinder. The cylinder is usually required to withstand pressure within 20Mpa (continuous pressure), and the application of mixing and pressure can even reach 55Mpa. General hydraulic cylinder made of carbon steel or low alloy   cold-drawn steel tube , such as ST52 E355, which treated by usually used to stress annealing. The heat treatment depends on the performance of the steel after cold working conditions of the hydraulic cylinder in actual production are mostly use the following heat treatment process for processing. Stress relief annealing adopts a heat treatment process lower than the heating temperature of recrystallization, which aims to eliminate the residual stress in the steel tube ca...

SKIVING AND ROLLER BURNISHING FOR CYLINDER BORES

  Hydraulic cylinder want to operate effectively, the cylinder’s ID must be precisely round and have a mirror-like surface finish to ensure a tight seal between it and the mating internal piston. This is commonly achieved through skiving and subsequent roller burnishing inside a tubular workpiece. Skiving uses a set of carbide blades positioned around the diameter of a tool to slice away chips and create a geometrically round bore. Roller burnishing , a cold-working process, uses multiple rollers to compress the peaks of material left behind after skiving to generate an extremely smooth surface finish. Burnishing also introduces a residual stress layer into the cylinder wall, which improves cylinder fatigue life. The skiving roller burnishing tool is a multifunctional tool used widely in the manufacturing of hydraulic cylinders and compared to honing the advantages are: • 80-90% saving of machine time which reduces tool costs per meter of tube length. • Produces super finish sur...
