Three-roller Plate Bender for ship building is mainly applied in the production of hulls of the ship which is often in circular arc shape. Based on the clients’ requirements, it can be designed either in symmetrical or in dissymmetrical pattern. The top part of the upper roller is configured with steel-made cross beam. And between the upper roller and cross beam as well as the bottom part of the lower roller, many groups of carrier rollers are installed on Plate Bender in order to improve the strength of the rollers and realize the synchronous driving of the three rollers. Application Hydraulic Plate Bender is widely used in petroleum, chemical industry, cement, boiler, shipbuilding, aviation, water conservancy, power transmission towers, etc. Functions: Three-roller Plate Bender embodies the functions of both plate rolling and bending, especially for arc sheer strake of bilge and pressing the grooved hatch, also for arc outer strake around the stern and engine room. components and advantages 1. Individual Roll Driven: Two bottom rollers are driven by individual reducers, which avoids the mechanical interference, extends the service life of the working rolls and improves the out-surface quality of work piece. 2. Flexing Compensation: There is an adjustable back-up roll device between the upper beam and upper back-up rollers, or the bottom beam and bottom back-up rollers. Bending Machine for Ship Building is driven by the plunger type cylinder to compensate the rolling deformation. The compensation, set by the deformation performance curve, guarantees high straightness of the work piece while processing the plates with different thickness and width.
