AI Technical Summary
Technical Problem
Existing double-rod double-acting hydraulic cylinders are complex to manufacture, time-consuming, involve many steps, and are cumbersome to install, resulting in low production efficiency and difficulties in transportation.
Method used
The piston rod adopts a split design, which simplifies the manufacturing process by combining components such as the piston rod, piston retaining ring, retaining key and combination seal, avoiding the welding process and directly using standard round steel for processing.
Benefits of technology
It simplifies the processing technology, improves production efficiency, avoids welding defects, reduces production costs, and improves product quality.
