W11 Series 3-Roll Mechanical Plate Bending Machine
Product Overview
The SLM W11 Series is a classic symmetrical 3-roll mechanical plate bending machine, engineered for reliability, simplicity, and exceptional cost-effectiveness. Utilizing a robust pyramid-style roller configuration, this machine is the industry standard for producing high-quality cylinders and arcs in light to medium-duty metal forming. It is the ideal solution for workshops specializing in industrial tanks, ventilation ducts, and steel structures where consistent performance and budget-efficiency are paramount.
Key Features
- High-Strength Forged Rollers: All rollers in our 3-roll mechanical plate bending machine are crafted from premium 42CrMo alloy steel, undergoing rigorous dual-stage heat treatment to ensure maximum surface hardness.
- Superior Structural Rigidity: The machine frame is a heavy-duty, fully welded steel structure that has been stress-relieved to provide a stable foundation for high-pressure rolling operations.
- Precision Mechanical Drive System: Equipped with a high-torque motor and a heavy-duty reduction gearbox, ensuring smooth power transmission and consistent rolling speeds.
- Symmetrical Pyramid Configuration: The top roller moves vertically to control the bending radius, while the two bottom rollers remain fixed as the main drivers.
- Simplified Maintenance: The streamlined mechanical design allows for easy access to all components, reducing long-term operational costs.
Working Principle
This 3-roll mechanical plate bending machine operates on the symmetrical bending principle. The top roller is positioned centrally above the two bottom rollers. By adjusting the vertical position of the top roller, the plate is pressed into the required curvature. As the two bottom rollers rotate, the friction drives the plate forward, completing the cylindrical or conical forming process through multiple passes.
