従来、此種軽量Ｃ形鋼はローラー成形装置にて成形され、そして、該ローラー 成形装置にて外部に押し出されるのであるが、このとき、特に該軽量Ｃ形鋼のリ ップ部に変形が生じるので之を次の手順によって矯正している。即ち、この矯正 手順を図５に従って説明する。図５（ａ）に示すように、前記軽量Ｃ形鋼１のフ ランジ２の先端部２ａ，２ａ及び後端部２ｂ，２ｂに力Ｆ1 ，Ｆ1 を加えて過大 曲げ加工を為し、更に図５（ｂ）に示すように前記軽量Ｃ形鋼１のフランジ２の 先端部２ａ，２ａ及び後端部２ｂ，２ｂに反対方向の力Ｆ2 ，Ｆ2 を加えて曲げ 戻しを行う。斯くして、前記軽量Ｃ形鋼１の先端部及び後端部の変形方向と逆方 向の曲げ応力を与えることにより成形後の変形を防止する。斯くして、図５（ｃ ）に示すように、該軽量Ｃ形鋼１の必要とされる許容差の範囲内に収まるように フランジ２の先端部２ａ，２ａ及び後端部２ｂ，２ｂを矯正している。又、図６ に示すように他の矯正法として該軽量Ｃ形鋼３のリップ４，４の先端部４ａ，４ ａ及び後端部４ｂ，４ｂに力Ｆ3 ，Ｆ3 を加えて、前記軽量Ｃ形鋼３の必要とさ れる許容差の範囲内に収まるように矯正している。Conventionally, this kind of lightweight C-section steel is formed by a roller forming apparatus and is extruded to the outside by the roller forming apparatus. At this time, however, deformation particularly occurs in the lip portion of the lightweight C-section steel. As it occurs, I am correcting it by the following procedure. That is, this correction procedure will be described with reference to FIG. As shown in FIG. 5 (a), forces F 1 and F 1 are applied to the front end portions 2a, 2a and the rear end portions 2b, 2b of the flange 2 of the lightweight C-shaped steel 1 to perform overbending, Further, as shown in FIG. 5 (b), the front ends 2a, 2a and the rear ends 2b, 2b of the flange 2 of the lightweight C-shaped steel 1 are subjected to bending back by applying forces F 2 , F 2 in the opposite directions. Thus, by applying bending stress in the direction opposite to the deformation direction of the front end portion and the rear end portion of the lightweight C-shaped steel 1, the deformation after forming is prevented. Thus, as shown in FIG. 5 (c), the front end portions 2a, 2a and the rear end portions 2b, 2b of the flange 2 are arranged so as to be within the required tolerance range of the lightweight C-section steel 1. I am straightening. Further, as shown in FIG. 6, as another straightening method, forces F 3 and F 3 are applied to the front end portions 4a and 4a and the rear end portions 4b and 4b of the lips 4 and 4 of the light weight C-shaped steel 3, and The lightweight C-section steel 3 is straightened so that it falls within the required tolerance range.
