Advanced 4-Roll Pre-Bending Technology: Unlike traditional 3-roll machines, this 4-roll system utilizes an independent side roller to pre-bend both ends of the plate in a single pass, eliminating the need for secondary pre-bending equipment and significantly reducing material waste.
CNC Intelligent Synchronization: Driven by a high-precision CNC system, the machine ensures perfect synchronization of the upper and side rollers. This guarantees consistent curvature across the entire width of the plate, which is critical for manufacturing high-pressure vessels and seamless pipes.
Versatile Conical Rolling Capability: Equipped with a tilting mechanism and conical rolling device, the machine can effortlessly produce tapered cylinders and cones, making it an indispensable asset for shipbuilding, wind tower manufacturing, and complex steel structures.
Heavy-Duty Hydraulic Powerhouse: Features a robust hydraulic system that provides immense downward force and precise roller positioning. This allows the machine to handle high-yield strength steel and thick plates (up to 200mm+) without compromising structural integrity.
Automated Production Workflow: Integrates seamlessly with modern manufacturing lines. The CNC system can store hundreds of bending programs, allowing operators to recall specific parameters instantly, ensuring high repeatability and reducing human error in mass production.
The CNC Hydraulic 4-Roll Plate Rolling Machine represents the pinnacle of modern metal forming technology, specifically designed for industries that demand absolute precision and structural integrity. While traditional 3-roll machines struggle with edge pre-bending and require multiple passes to achieve a perfect circle, this 4-roll configuration solves those challenges through its unique mechanical layout.
