Abstract
PURPOSE:To form a flange part having no defective forming by constraining the root part of a preformed panel part and bending a tongue piece part with constraining the root of the tongue piece part by pressing it by a pad and floating die. CONSTITUTION:A panel parts P is subjected to drawing and trim piercing to form a tongue piece part Q having a fitting hole at the end and almost chevron- like section. This preformed panel part P is set on the punch 2 supported by the elastic body 3 of a pressing device. An upper die 9 is then descended to interpose said panel P by pressing it between the punch 2 and a pad 2. The upper die 9 is descended further to constrain the part near the root of the tonguelike part Q by pressing it with a pad 7 and the floating die 10 which is arranged at the part near the punch 2 of the inside of a sectional die 4 and supported by an elastic body 11. With further descent of the upper die 9, the tongue-like part Q is bent in the specified shape in cooperation with the three of the pad 7, sectional die 4 and floating die 10, and a flange part F is formed.
