Hydraulic Unwinding MachineIt Is The Starting Key Equipment For Metal Coil Processing Production Lines (such As Longitudinal Cutting, Transverse Cutting, Stamping, Color Coating, Etc.). Its Main Function Is To Carry And Unfold Large Tonnage Raw Steel Coils, Providing Continuous And Stable Supply Of Strip For Subsequent Straightening, Cutting, Stamping And Other Processes.
The Core Feature Of This Device Is The Use Of A Hydraulic System As The Power And Control Core, And Its Typical Structure Includes:
1. Hydraulic Expansion And Contraction Drum: The Wedge-shaped Mechanism Is Driven By Internal Hydraulic Oil To Radially Expand The Fan-shaped Plate Of The Drum, Thereby Firmly Supporting The Steel Coil From The Inside. When Unloading The Coil, Hydraulic Pressure Relief Causes The Drum To Shrink, Making It Easier For The Steel Coil To Be Removed.
2. Hydraulic Drive System: Provides Rotational Power For The Drum To Achieve Unwinding Rotation, And Often Has Two Modes: Passive (pulled By Subsequent Equipment) And Active (driven Discharge).
3. Hydraulic Support And Adjustment Mechanism: Including Hydraulic Lifting Saddles (or Carts) For Load-bearing And Lifting Steel Coils, As Well As Hydraulic Sliding Bases For Controlling The Overall Movement Of Equipment To Align With The Production Line.
4. Auxiliary Hydraulic Unit: Drives Auxiliary Devices Such As Pressure Arm And Oil Scraper.
The Workflow Is As Follows: Firstly, The Steel Coil Is Placed On The Saddle Of The Unwinding Machine Through Feeding Equipment (such As Cranes, Feeding Carts); Subsequently, The Hydraulic Lifting Mechanism Lifts The Steel Coil To The Center Height, And The Hydraulic Sliding Base Moves To Align The Equipment With The Production Line; Next, The Hydraulic Expansion And Contraction Drum Is Inserted Into The Inner Hole Of The Steel Coil And Tightened; Finally, Under The Linkage Control, The Uncoiler Releases The Strip At The Set Tension Or Speed And Enters The Subsequent Process.
The Advantages Of Hydraulic Uncoiler Lie In Its High Load-bearing Capacity, Sturdy Structure, And Reliable Clamping. Especially Suitable For Processing Heavy And Wide Steel Coils. The Hydraulic System Can Provide Tremendous Clamping Force And Smooth Driving And Control, With Strong Overload Resistance. By Integrating Functions Such As Automatic Centering, Edge Correction, And Tension Control, The Stability Of The Unwinding Process And The Accuracy Of The Tape Travel Path Can Be Ensured.
