Acting piston rod supports connecting parts, most of the applications in the cylinder, the cylinder movement execution units, and is a frequent movement of high technical requirements of moving parts. A hydraulic cylinder, for example, by the: cylinder, the piston rod (cylinder rod), the piston cap of several parts. Its processing quality directly affects the entire product life and reliability. High processing requirements of the piston rod, the surface roughness is Ra0.4 ~ 0.8um, concentricity, wear demanding. The basic characteristics of the cylinder rod is elongated axis machining, the machining difficult, has been plagued by processing staff.


Processing Technology 

Using Rolling 

Thereby improving the corrosion resistance of the surface, and can delay fatigue cracks or expanded, thus increasing the fatigue strength of the cylinder rod. Forming by rolling, cold rolling the surface layer of the hardened layer, the elastic and plastic deformation to reduce the grinding surface of the auxiliary contact, thereby improving the wear resistance of the surface of the cylinder rod, while avoiding burns caused by grinding. After rolling, the surface roughness is reduced, with improved properties. At the same time, reducing the friction damage to seals or seal when the cylinder piston rod, and improve the overall service life of the fuel tank. Rolling process is an efficient quality process measures.

Usage 

Mainly used for hydraulic and pneumatic piston, engineering machinery, automobile manufacturing piston rod, guide pillar plastic machinery, packaging machinery, printing machinery rollers, textile machinery, transportation machinery axis, linear motion of the linear axis.


Stainless steel is mainly used for hydraulic and pneumatic piston, engineering machinery, automobile manufacturing piston rod. Piston rod rolling process, leaving the surface because the surface layer of compressive residual stress, helps a closed surface microcracks impede erosion expansion. Thereby improving the corrosion resistance of the surface, and can delay fatigue cracks or expanded, thus increasing the fatigue strength of the cylinder rod. Forming by rolling, cold rolling the surface layer of the hardened layer, the elastic and plastic deformation to reduce the grinding surface of the auxiliary contact, thereby improving the wear resistance of the surface of the cylinder rod, while avoiding burns caused by grinding. After rolling, the surface roughness is reduced, with improved properties. At the same time, reducing the friction damage to seals or seal when the cylinder piston rod, and improve the overall service life of the fuel tank. Rolling process is an efficient quality process measures, is a mirror with a diameter of 160mm cut rolling head Dr. cards (45 steel seamless pipe) as an example to prove rolling effect. After rolling, the surface roughness of the cylinder rod roll before Ra3.2 ~ 6.3um buildings reduced to Ra0.4 ~ 0.8um, the surface hardness of the cylinder rod is increased by about 30 percent, the cylinder rod surface fatigue strength increased by 25%. Cylinder life, increased by 2 to 3 times higher than the rolling process to improve the efficiency of the grinding process about 15 times. The above data shows that the rolling process is efficient and can greatly improve the surface quality of the cylinder rod.
