Abstract
PURPOSE: To form a C-shaped member simply and effectively by small number of processes by holding the center of a plate with a punch and a plate holder, and at the same time, bending the side of the plate with a forming roll and bending the end of the plate with a flange bending edge.
CONSTITUTION: A plate 24 is placed on a drag 23 and a punch 23 fixed on a base stand 21. A cope base plate is lowered and the center of the plate 24 is held together with the punch 23 with a plate holder 26 hung from the base plate 27. At the same time, the side of the plate 24 is bent along the side of the punch 23 by a forming roll 30 attached through a support 29 to the cope 28 placed on the cope base plate 27. Then, a flange bending edge 34 attached to a holder 37 is driven by a hydraulic cylinder 39 installed on the inclined face of a pedestal on the base stand 1, and the end of the plate 24 is pressure welded and bend at the lower corner 34 of the punch 23. By this way a member having C-shaped cross-section can be obtained easily, after this. It is formed so that legs on both sides of the flat part makes an acute angle with the flat part.
