Description

Technical Field

[0001] The utility model relates to the field of lightweight variable-luffing oil cylinders, in particular to a lightweight piston rod variable-luffing oil cylinder. Background Art

[0002] A lightweight piston rod luffing cylinder is a hydraulic actuator used in engineering and mechanical applications. It is usually used to produce linear or rotational motion. The piston rod of this cylinder is designed to be lighter, aiming to reduce its own mass, thereby improving the efficiency and performance of the system. The piston rod is usually made of high-strength, lightweight materials such as aluminum alloy or carbon fiber composite materials to reduce its mass. This lightweight piston rod luffing cylinder is often used in engineering and mechanical applications that require speed, precision and energy saving, such as machine tools, molds, automation equipment, etc.

[0003] In the specific use of lightweight piston rod variable-length cylinders, the cylinder barrel is an important component of the cylinder. The wall thickness of the cylinder barrel can effectively improve the strength of its structure and make its performance more stable. However, the overall weight is heavy. If the wall thickness of the cylinder barrel is reduced, although the overall weight can be reduced, the strength of the entire structure will be reduced. Therefore, it is particularly important to optimize it under the premise of ensuring performance, so as to reduce the overall weight while taking into account strength. Utility Model Content

In addition, a sealing ring 24 can be arranged to seal the connection between the bottom cylinder 12 and the head cylinder 13, which can improve the sealing performance, and an electroplated anti-corrosion layer is arranged at the sealing ring 2 and the limit ring 25 to improve the corrosion resistance, thereby extending the service life of the device and facilitating the operator to use it. At this point, all processes are completed.
