The CNC four-roller automatic rolling line is a highly automated sheet metal processing machine. Its CNC system automates the entire process, from sheet material removal to coiling.
The CNC four-roller automatic rolling line consists of a stacking platform, an automatic material removal device, an automatic moving device, an automatic feeding device, a CNC plate rolling machine, including an automatic coiling device. A post-weld cylinder removal device and a conveying system. These systems automatically position, convey, coil, and discharge the sheet metal.
Technical advantages and features of the four-roller automatic rolling line
No mold restrictions
The CNC system adjusts the roller pitch and coiling radius to produce various cylinder sizes without the need for specialized molds.
High-precision control
Supports workpiece data programming and storage, enabling automatic, one-click coiling, ensuring coiling accuracy and efficiency.
Automated production process
The integrated stacking, material removal, conveying, coiling, and discharge process automates the entire process from sheet metal to finished product, significantly improving production efficiency.
High-Precision Control and Stability
Utilizing an intelligent PLC control system, the upper and lower rollers and side rollers rise and fall synchronously with an accuracy of ±0.15mm, ensuring stable and consistent roll dimensions.
Pre-bending and Straight-Edge Optimization
The lower and side rollers can be tilted to pre-bend the sheet ends, reducing the remaining straight edge length (typically ≤5mm), streamlining the process and reducing labor intensity.
Wide Applications
Suitable for rolling cylindrical, conical, and curved metal sheet shapes, commonly used in industries such as boilers, shipbuilding, petrochemicals, and machinery manufacturing.
Thick Plate Processing
Capable of processing thick steel plates that are difficult to bend using conventional methods, expanding the material's application range.
Process Simplification and Efficiency Improvement
No additional pre-bending equipment is required, driven by roller friction, reducing process steps, improving production speed, and increasing workpiece quality.
Conclusion of the four-roller automatic rolling line
In summary, the four-roller automatic roll-to-roll line, with its automation, high precision, and process optimization, has become an efficient and reliable choice for modern metalworking. This plate rolling machine is widely used in shipbuilding, hydropower, boiler, aviation, and motor manufacturing industries. It is suitable for bending metal plates into complex shapes such as cylinders and cones.
