Abstract:
A forming apparatus and method for minimizing wrinkling in the forming of a three-dimensional component from a two-dimensional blank. The forming apparatus includes vertically opposed sets of tools or binders. A first tool or binder apparatus has first and second sets of opposed sides having contoured binder surfaces. A second tool or binder apparatus is mounted in vertically opposed relation to the first binder apparatus, and includes first and second sets of opposed tool or binder segments that have contoured binder surfaces thereon that are complementary in shape to the respective binder surfaces of the first and second sets of opposed sides of the first binder apparatus. One of the first and second sets of opposed binder segments of the second binder apparatus have substantially similar contours and the other have different contours. One of the first and second sets of opposed binder segments of the second binder apparatus is elevated and movable with respect to the other.
