Rolling

 

roll forming, a closed-impression die forging process for billets, using rotating dies (sectors) mounted on the machine’s forging rolls. The billet is placed between the rolls when they are in the idle position. The rolls, turning in opposite directions, seize the billet and deform it. This is a high-productivity process from which accurate billets can be obtained with a high metal capacity factor. It is used in the fabrication of connecting rods, conveyor links, and other machine parts, and also in obtaining shaped billets of irregular cross section for subsequent forging by presses and hammers. Small cantilever forging rolls are frequently used to roll shaped billets. Hot rolling of billets and finish forging of turbine and compressor blades are both widespread. Accurate cold rolling permits the elimination of mechanical processing of blades. Rolling provides for the continuous deformation and orientation of the metal fibers in accordance with the configuration of the part, thus imparting excellent mechanical properties to it.
