AI Technical Summary
Technical Problem
In the current processing of copper and copper alloy strip, manual expansion and contraction drum operation is difficult and lacks precision, resulting in poor safety and high consumption of manpower and physical strength.
Method used
It adopts a hydraulic expansion and contraction drum structure, which uses a hydraulic cylinder to drive the spindle to push the flange and bushing. Combined with the dovetail protrusion and groove structure, it realizes the automatic expansion and contraction of the drum, replacing the traditional manual thread drive.
Benefits of technology
It improves operational flexibility and precision, reduces manpower consumption, and enhances safety and operational reliability.
