Adhering to the concept of "quality and brand", Huabang adheres to high starting point and high level development and construction. Unite excellent talents, introduce advanced equipment, establish a strict and scientific management system, and implement strict enterprise standards for the whole production process. The main quality control parameters are higher than national standards and international standards.
The piston rod shall be 45 # steel, F=120KN, according to the working environment and service performance of the hydraulic cylinder[ σ]= 475MPa, d=78.23mm, d=80mm after rounding
(2) Piston rod length L
According to the stroke of hydraulic cylinder and the structure of hydraulic cylinder, the length of piston rod is 1950mm.
(3) Structural Design of Piston Rod
The outer end head of the piston rod is connected with the drag mechanism of the load. In order to avoid eccentric load force generated by the piston rod during work, adapt to the installation requirements of the hydraulic cylinder, and improve its efficiency, according to the working parameters, the piston rod head of the hydraulic cylinder design should be designed as a stepped shaft threaded structure, which can improve the processing performance and facilitate installation. The end is designed with threaded connection. Head structure is as shown in the figure
(4) Sealing and dustproof of piston rod
With reference to the normal hydraulic cylinder manufacturer and the function of this hydraulic cylinder, two Yx shaft seals and two O-ring seals are selected for the connection between the secondary piston rod and the piston. Select an O-ring to seal with the guide sleeve, select an A-type dust ring and a U-type seal ring to connect with the end cover! See the general drawing of hydraulic cylinder for details.
(5) Calculation of piston rod strength
The distance between the load connection point at the end of the piston rod and the hydraulic cylinder support is, if:
10d (obviously this is true)
