The C45 piston rod is a connecting part that supports the work of the piston. It is a moving part with frequent movement and high technical requirements, which is mostly used in the moving parts of the oil cylinder and the pneumatic cylinder. Taking the pneumatic cylinder as an example, it is composed of cylinder tube, piston rod (cylinder rod), piston and end cover. The quality of its processing directly affects the life and reliability of the whole product. Piston rod processing requirements are high, its surface roughness requirements are Ra0.4 ~ 0.8um, coaxiality, wear resistance requirements are strict. The basic feature of cylinder rod is elongated shaft processing, which is difficult to process and has been troubling the processing personnel. The piston rod is mainly used in hydraulic pneumatic, construction machinery, car manufacturing piston rod, plastic machinery guide column, packaging machinery, printing machinery roller, textile machinery, transmission machinery axis, linear motion with linear optical axis.
The main provisions of the piston rod:
(1) to have sufficient compressive strength, bending stiffness and reliability.
(2) Good wear resistance and high machining accuracy and surface roughness.
(3) The structure type should avoid the damage of stress as far as possible.
(4) Ensure that the connection is reliable and avoid loose.
(5) the formulation of the piston rod structure should be conducive to the disassembly of the piston.
