The W11NC Series Marine Plate Rolling Machine is mainly used for rolling arc plates such as ship hulls and pressing grooved bulkheads. According to customer requirements, it can be designed as a symmetric or asymmetric three-roll plate rolling machine. A rigid girder is arranged above the upper roll, and multiple sets of supporting rolls are installed between the upper roll and the girder as well as below the lower rolls to enhance the rigidity of the upper and lower rolls. All three rolls are driven.

The types of marine plate rolling machines can be divided into the following categories:

a) Symmetric upper-adjustable type: The upper working roll can move up and down vertically, while the positions of the two lower working rolls remain relatively fixed.

b) Integral horizontal lower-adjustable type for lower rolls: The upper working roll moves up and down vertically, and the two lower working rolls perform an integral horizontal translational movement.

c) Independent horizontal lower-adjustable type for lower rolls: The upper working roll moves up and down vertically, and the two lower working rolls perform independent horizontal translational movements respectively.

d) Universal upper roll type: The upper working roll can move up and down vertically and also perform horizontal translational movement, while the positions of the two lower working rolls remain relatively fixed.

Key Advantages

1. High Forming Precision: The hydraulic system dynamically adjusts pressure with an error controlled within 0.5%—far superior to the 2%-3% of traditional mechanical equipment—ensuring millimeter-level bending precision for key components such as keels.

2. High Working Efficiency: The microcomputer-controlled four-roll design supports pre-bending of plate ends and roll forming, which can be completed without plate turning, significantly improving processing efficiency.

3. Strong Reliability: The working rolls are made of 42CrMo high-strength material and undergo forging and quenching-tempering treatment, featuring excellent wear resistance and a long service life. The fully enclosed design provides dust protection and facilitates maintenance.

4. Versatility: Some models integrate both plate rolling and bending functions, and can roll arc or conical workpieces with a central angle of less than 180 degrees, adapting to different processing requirements.

5. Easy Operation: Centralized computer control supports full NC/CNC operation, simplifying the processing workflow.
