Upper Roller Universal Rolling Machine for Industrial Plate Bending

The Upper Roller Universal Rolling Machine is a high-performance metal forming solution designed for bending medium and thick plates with exceptional accuracy. Its upper roller-driven structure allows for powerful and flexible rolling performance, making it ideal for heavy-duty industrial applications such as pressure vessels, shipbuilding, wind towers, and large steel structures.

Working Principle of Upper Roller Universal Rolling Machine

The machine operates on the three-roller bending principle, where the upper roller applies downward pressure on the metal sheet while the two lower rollers rotate to form the plate into a circular or conical shape.
In this design, the upper roller performs vertical and horizontal movement, achieving precise bending control and ensuring uniform material deformation throughout the process.

Key technical benefits include:

• Hydraulic drive system providing stable power transmission.

• Automatic balancing mechanism ensuring precise roller alignment.

• Digital display control for bending angle and rolling pressure.

• High torque output for thick and wide plate processing.

Structural Features of the Machine

Robust Frame Construction

The machine adopts a welded steel frame that undergoes stress-relief treatment, ensuring structural rigidity and long-term durability under continuous heavy-load operations.

Advanced Hydraulic System

Equipped with electro-hydraulic synchronization technology, the system allows smooth roller movement, fast response, and precise positioning control.

High-Strength Rollers

The rollers are made from forged alloy steel, hardened and precision-ground to resist wear and maintain accuracy during long-term use.

Automatic Cone Bending Function

With adjustable side rollers and tilting mechanisms, the machine can easily form conical and cylindrical shapes without additional tooling, enhancing versatility for industrial fabrication.

Applications of the Industrial Plate Bending Machine

The Upper Roller Universal Rolling Machine is widely used across industries requiring precision metal plate forming:

• Pressure Vessel Manufacturing – forming cylindrical shells and tank walls.

• Shipbuilding – bending large hull plates with consistent curvature.

• Wind Power Industry – rolling tower sections with high dimensional accuracy.

• Construction and Engineering – fabricating structural steel components.

• Machinery Production – shaping casings, frames, and support rings.

Its multi-function design enables efficient forming of mild steel, stainless steel, aluminum, and high-tensile alloy plates.

Advantages of Using Upper Roller Universal Rolling Machine

• High Bending Precision: Controlled by digital or CNC systems for consistent results.

• Flexible Operation: Suitable for different thicknesses and diameters.

• Reduced Material Waste: Optimized pre-bending minimizes scrap.

• Efficient Production: Hydraulic-assisted rolling reduces manual labor.

• Long Service Life: Heat-treated rollers ensure stability and wear resistance.

FAQ：

Q1: What is the working principle of the upper roller universal rolling machine?

It uses an upper roller for vertical and horizontal movement to press and roll the plate while the lower rollers rotate, forming the material into a cylindrical or conical shape.

Q2: What materials can be processed by this rolling machine?

It can handle carbon steel, stainless steel, aluminum, copper, and high-strength alloy plates used in heavy industrial fabrication.

Q3: How is the pre-bending performed?

Pre-bending is done by adjusting the roller position to curve the plate edges before the final rolling process, ensuring a seamless joint and reducing flat ends.

Q4: What is the difference between upper roller and lower roller rolling machines?

The upper roller type provides better control for heavy and thick plates, allowing for both vertical and horizontal roller movements, while lower roller types are more common for thin sheets.

Q5: Does JSC provide customization options?

Yes. Roller diameters, bending lengths, and control systems (manual, hydraulic, or CNC) can all be customized according to your specific production needs.
