    • PURPOSE: A roll forming method and a formed beam produced by using the same is provided to roll-form an inner cross section of a radius curvature direction into an incurved surface primarily, thereby preventing a binding phenomenon generated in a curvature forming process by using the incurved surface. CONSTITUTION: A roll forming method comprises the following steps: a roll forming step of primarily forming an incurved surface(I) by successively bending one surface of a formed beam(30) in order to have a closed cross section by using a multistage roller former; and a bending step of curvature-forming the formed beam at multiple stages by arranging the incurved surface of the formed beam to an inner side of a radius curvature direction.
    • 目的:提供一种辊成形方法和使用该成形方法制成的成形梁,以将半径曲率方向的内横截面主要卷成弯曲表面,从而防止在曲率形成过程中产生的结合现象, 弯曲的表面。 构成:辊成形方法包括以下步骤:辊成型步骤,主要通过使用多级辊轧机(I)连续地弯曲成形梁(30)的一个表面以形成闭合截面来形成弯曲表面(I) ; 以及通过将所形成的光束的弯曲表面布置到半径曲率方向的内侧,在多个阶段对形成的光束进行曲率形成的弯曲步骤。
