Working Principle of Plate Rolling Machines
A plate rolling machine shapes metal by feeding flat plates into rollers. These machines commonly use three or four rollers, which are either in a linear or pyramidal setup. The upper roller, located at the apex of the pyramid or upper side in a linear setup, presses down on the plate. The lower or side rollers, situated at the bottom or sides, respectively, depending on the configuration, adjust their bend radius to control the shape. By continuously changing the rolling radius and re-feeding the plate, the machine can gradually shape the workpiece into cylinders, cones, and other shaped forms. Achieving the desired shape depends on the right amount of force and precise control.
How a Plate Roll Operates
Leveraging mechanical engineering and forces, metal bending is accomplished with precision on specialised plate rolls. Contemporary machinery comes equipped with features that ensure greater efficiency and accuracy, as well as the ability to work with various materials, including steel, aluminum, stainless steel, and others, at different thicknesses. For instance, some industrial plate rollers are capable of bending plates as thick as 6 inches and as wide as 20 feet, for use in shipbuilding, construction, and industrial manufacturing.
The first step typically involves placing the metal plate on the rollers and ensuring it is positioned correctly. Depending on the construction, a machine may have either three or four rollers: one top roller that supplies the bending force and the side and bottom rollers that provide the necessary support and fine-tuning. Since precision is crucial, CNC (Computer Numerical Control) systems are usually found in the newer plate rolls to achieve the required precision and duplication. Such systems can save numerous bending parameters, which facilitates switching between tasks and dramatically shortens the ramp-up time for batch jobs.
Both torque and pressure, along with the speed of the rollers, are important ratios that need to be fine-tuned during the operation. The bending is achieved through plastic deformation, which is controlled by applying pressure that stretches the metal to a point greater than its elastic limit, thereby attaining the desired permanent curved shape. Moreover, these machines commonly feature hydraulic or electric motors, which provide the necessary force to work on even the hardest materials.
