Roll bending, also known as plate rolling or cylinder bending, is a metal forming process used to bend and shape flat sheets or plates into cylindrical or curved shapes. This process typically involves passing the metal between three rolls arranged in a pyramid formation, with the top roll applying downward pressure and the two bottom rolls providing support and forming the desired curvature.
During the roll bending process, the metal is gradually fed through the rolls, and as it passes through, the top roll applies pressure while the bottom rolls rotate to guide the metal and create the desired curvature. The curvature achieved depends on various factors, including the thickness and width of the metal, the diameter of the rolls, and the pressure applied by the top roll.
Roll bending is commonly used in various industries, including construction, manufacturing, and metal fabrication, to produce a wide range of curved components such as cylinders, cones, pipes, and structural beams. It offers advantages such as versatility, precision, and the ability to produce complex shapes with consistent quality.
Overall, roll bending is a versatile and efficient metal forming process that allows for the creation of a wide range of curved components used in various applications.
