Upper Roller Universal Rolling Machine for High-Precision Metal Bending

The Upper Roller Universal Rolling Machine is an industrial-grade plate bending solution designed to handle thick steel plates and achieve high-precision curvature forming. This machine uses a top roll that moves vertically while the two bottom rolls support and drive the material. Due to its robust design and high forming accuracy, it is widely adopted in industries such as shipbuilding, wind tower production, and pressure vessel fabrication.

 

Precision Rolling Capability in Thick Plate Fabrication
This machine delivers exceptional control over material deformation, especially when working with plates above 20mm in thickness. Its hydraulic system ensures consistent force application, minimizing spring-back and reducing the need for secondary processing. Equipped with CNC or NC controls, the operator can adjust roll positions precisely, achieving tight tolerances within ±0.2mm.

 

Hydraulic System for Stable and Powerful Operation
The machine integrates a full-hydraulic control system, allowing synchronized movement of the upper roller with real-time pressure feedback. The hydraulic cylinders provide powerful, consistent lifting force for the upper roll, ensuring efficient deformation of high-strength steels like Q345 or stainless steel 304/316. The system also features overload protection and automatic pressure balancing for safety and stability.

 

Universal Forming for Cone, Arc, and Cylinder Shapes
One of the unique advantages of the Upper Roller Universal Rolling Machine is its ability to roll both cylindrical and conical parts without additional tooling. Through independent side roller adjustment and asymmetrical roller movement, operators can pre-bend and roll tapered sections required in ducts, pressure vessels, or industrial chimneys, making the machine highly versatile for custom metal fabrication.

 

Structure and Material Strength
The frame is welded from high-tensile steel and stress-relieved to ensure rigidity under continuous heavy-duty operation. The rolls are made of 42CrMo hardened and tempered steel, induction-hardened to HRC 50-60 for wear resistance. All bearings are heavy-load spherical types to support axial and radial forces during rolling operations.

 

Application in High-Tonnage Industries
Upper Roller Universal Rolling Machines are a critical asset in sectors requiring wide and thick plate processing. These include:

Shipbuilding: Rolling hull sections and curved bulkhead panels.

Wind Tower Manufacturing: Forming large-diameter towers from heavy plates.

Pressure Vessel Production: Creating precise cylindrical shells for boilers and tanks.

Steel Structure Fabrication: Rolling beams and plates for bridges and industrial buildings.

 

Automation and Digital Controls for Operational Efficiency
Advanced models integrate PLC or CNC systems for intelligent parameter setting. Operators can program sequence steps for pre-bending, rolling, and final shaping. Touchscreen interfaces offer real-time data visualization, alarm logs, and roll position tracking. This reduces manual error and increases output consistency.

 

Maintenance and Longevity
Designed for long-term industrial use, the Upper Roller Universal Rolling Machine features centralized lubrication systems, wear-resistant components, and accessible service points. Daily maintenance involves checking hydraulic fluid levels, verifying sensor feedback, and inspecting roll surfaces for wear. Scheduled servicing keeps the system performing within optimal parameters.

 

Safety and Compliance Features
The machine includes safety interlocks, emergency stops, and light curtains (optional). All models comply with CE standards and can be customized for other international safety requirements. Pressure relief valves, hydraulic locks, and electrical fail-safes prevent machine damage and operator injury during fault conditions.

 

FAQs:

What is the main advantage of an upper roller design in rolling machines?
The upper roller provides centralized vertical pressure, which ensures uniform material deformation, especially on thick plates. It enhances pre-bending accuracy and allows more efficient control of the forming process.

Can upper roller universal rolling machines form conical shapes?
Yes. With independent side roller movement and tilt adjustment, these machines can form precise conical shapes without needing additional tooling or setups.

How do I maintain the rolling accuracy over time?
Regular calibration of the CNC system, inspection of the hydraulic components, and surface cleaning of rollers help maintain long-term accuracy. Roll alignment checks and software updates are also crucial.

What material types can the machine handle?
It can roll carbon steel, stainless steel, aluminum alloys, and high-tensile plates. The machine's hydraulic power and roll material are designed to accommodate both ductile and hard metals.

Is this machine suitable for automatic production lines?
Yes. It can be integrated with automatic feeding tables, output conveyors, and robotic welding stations, enabling high-efficiency production lines for pressure vessel or structural steel fabrication.
