W12 hydraulics plate rolling machine with 4 rolls W12-35x1000
A four-roll plate bending machine is an advanced industrial equipment designed for precision bending of metal sheets into cylindrical, conical, or arc-shaped components. Compared to traditional three-roll machines, its four-roll configuration (comprising two upper rolls and two lower rolls) ensures superior control, reduced material waste, and enhanced efficiency.
Description
4 rolls Hydraulic plate bending machine with double pre-bending.
Useful length from 1000mm to 6000mm.
Thickness from 2 up to 100mm.
With our four rolls plate bending machine,plate can be bent on both side without return.Full automatic controlled by PLC,there’s no need for additional processing steps for bending the ends.The flat edge is 1.5-2 times of the thickness.
Quality certificate such as CE and ISO9001.
Key Features & Advantages:
- High Precision: The four-roll system minimizes plate slippage and eliminates the need for pre-bending edges, ensuring consistent curvature and smooth surfaces.
- Automated Operation: Equipped with CNC (Computer Numerical Control) systems, it allows programmable adjustments for complex bending tasks.
- Material Versatility:Capable of handling various metals (steel, stainless steel, aluminum, etc.) with wide thickness and width ranges.
- Energy Efficiency: Reduced idle rolling and optimized workflow lower operational costs.
- End-to-End Forming: The dual lower rolls grip the plate securely, enabling complete bending without repositioning.
Applications:
Widely used in industries such as shipbuilding, pressure vessels, wind towers, pipelines, and structural steel fabrication.
Technical Parameters (Example):
- Bending Thickness: 6–150 mm (varies by model)
- Maximum Plate Width: Up to 6000 mm
- Roll Diameter: Customizable for material rigidity
- Control System: Hydraulic-driven with CNC
This machine is ideal for heavy-duty industrial applications requiring high productivity and repeatable accuracy.
