Opening Machine: A Core Aid in Metalworking
2025/03/25 23:45
The unwinder is a key piece of equipment in the metal sheet processing workflow, playing a vital role in steel strip, aluminum strip, and copper strip rolling lines, as well as in various auxiliary lines such as color coating and galvanizing lines.
The unwinder boasts an ingenious design. Its body uses a welded box structure, ensuring stability and durability to withstand significant external force impacts and vibrations, maintaining operational stability. A variable frequency drive motor paired with a gearbox provides strong and stable power output to the reel shaft. The unwinding speed can be flexibly adjusted according to different production needs. The reel shaft is hollow and supported by bearings in the gearbox body, coupled with a drive spur gear for more efficient power transmission. An outer support bearing is also located at the front end of the core shaft to enhance reel rigidity and stability.
Its expansion and contraction mechanism is uniquely designed. The core shaft connects to the fan-shaped plate via an inclined dovetail groove. The rotary oil cylinder at the tail end of the reel shaft drives the piston rod and connecting rod, causing the quadrilateral shaft to slide axially, thus allowing the fan-shaped plate to expand and contract radially, securely clamping steel coils of different inner diameters.
The unwinder features a high degree of automation. Equipped with an advanced control system, operators only need to set parameters on the control panel; it automatically completes a series of processes including coil loading, unwinding, and tension control, improving production efficiency, reducing labor costs, and minimizing operational errors. Furthermore, it has a central control (CPC) function for automatic steel strip centering, ensuring the steel strip remains correctly positioned during unwinding, guaranteeing smooth subsequent processing.
