Abstract
A bending die includes a first die portion for bending a stretch portion of a composite flange and a second die portion for bending a straight portion of the composite flange. The first die portion has a first inclined surface inclined at a first angle with respect to a horizontal direction, and the second die portion has a second inclined surface inclined at a second angle with respect to the horizontal direction. The second angle is smaller than the first angle. As a result, when the bending die is moved toward the composite flange, the first inclined surface begins to contact the stretch portion before the second inclined surface contacts the straight portion, so that a warp is prevented from being generated in the composite flange.
