Piston rod can be applied to the hydraulic starter when it is used. The processing requirement of the product is relatively high, so the quality of the hydraulic cylinder is mostly the quality of the piston rod, and the piston rod is supported. The connecting parts of the piston work are mostly used in the cylinder, cylinder (compressed air) motion executing parts, and are a moving part with frequent movement and high technical requirements. The hollow piston rod refers to a hollow piston rod having an annular cross section.
The quality of the piston rod directly affects the life and reliability of the entire product. The 45# piston rod supports the connecting parts of the piston work. Most of them are used in the cylinder and cylinder movement executing parts. It is a moving part with frequent movement and high technical requirements. The hydraulic piston rod improves the surface corrosion resistance and can delay the generation or expansion of fatigue cracks, thereby improving the fatigue strength of the cylinder rod. The cylinder piston rod wear ring can improve the guiding of the cylinder, reduce the wear of the piston seal and reduce the frictional resistance. The hydraulic piston rod cylinder, the piston rod (cylinder rod), the piston and the end cover are composed of several parts. The piston rod has high processing requirements, and its surface roughness is required to be Ra 0.4 to 0.8 um, which requires strict requirements for coaxiality and wear resistance.   Although the piston rod is considered from the angle of the design idea (consider) does not want to bear the radial force, it is directly limited by the actual structure when it is used, and the piston rod of the hydraulic cylinder is inevitable. The ground is subjected to a considerable portion of its radial external force. For this reason, the length of the hydraulic cylinder piston must be appropriate, generally taking 0.7 to 1.0 times the outer diameter (outer diameter) of the piston rod. The piston rod increases its guiding action and increases the bearing surface area, thereby achieving the purpose of reducing wear and increasing the length of time used by the hydraulic cylinder. The quality of the hydraulic cylinder largely depends on the quality of the piston rod, and therefore for the piston. Processing should require geometric accuracy with sufficient accuracy (accuracy). Generally speaking, the outer diameter of the piston, the roundness of the inner hole, and the deviation of the cylindricity cannot be greater than half of the dimensional tolerance; the outer diameter of the outer diameter of the piston rod and the sealing groove (gōucá o) should be 0.02 mm. Within. Generally, the vertical tolerance of the end face of the hydraulic cylinder to the axis of the hydraulic cylinder is less than 0.04 mm/100 mm.
