To provide a wall panel manufacturing method that can process a plural types of steel plates to which sheets having different thickness and stretch ratio are attached without replacing press die on one line and form a wall panel with high appearance quality by suppressing variations of a finished state.SOLUTION: A manufacturing method of a wall panel 30 comprises: B1 step to prepare a plate 10 to which a sheet 39 is attached and form a cutout portions 25, 26 including curve portions 27A, 28A; C1, C2, C3 steps to bend a first short side 15, a first long side 17, a second long side 18 at predetermined positions in parallel; and D1 step to finish corner portions 19, 20 by drawing process to bring a roller 76 rotatably in contact with unbent portions 27B, 28B. Shapes of curve portions 27A, 28A are constant regardless of thickness and stretch ratio of the sheet 39 in the B1 step. The drawing process is performed by changing a distance between a pressing member 74 and the roller 76 according to the thickness and the stretch ratio of the sheet 39 in the D1 step.SELECTED DRAWING: Figure 16
【課題】厚さや伸縮率が異なるシートが貼着された複数種類の鋼板を、一つのラインで、プレス金型を交換することなく加工でき、仕上がり状態のばらつきを抑えて、外観品質の高い壁パネルを形成できる製造方法を実現する。【解決手段】本発明に係る壁パネル３０の製造方法は、シート３９が貼着された板材１０を用意して、曲線部２７Ａ、２８Ａを含む切欠き部２５、２６を形成するＢ１ステップと、第１短辺１５、第１長辺１７、第２長辺１８とそれぞれ並行する所定位置で折曲するＣ１、Ｃ２、Ｃ３ステップと、曲げ残し部２７Ｂ、２８Ｂにローラー７６を転接させる絞り加工によりコーナー部１９、２０に仕上げるＤ１ステップとを備え、前記Ｂ１ステップでは、シート３９の厚さや伸縮率にかかわらず曲線部２７Ａ、２８Ａの形状を一定とし、前記Ｄ１ステップでは、シート３９の厚さや伸縮率に応じて、押え部材７４とローラー７６との間隔を変化させて絞り加工を行う。【選択図】図１６
