Abstract

A prototype part drawing/flanging tool is provided that are arranged in a draw die set-up and a flange die set-up. The draw die set-up includes a binder ring, a pad; a flange forming ring, and a punch. The flange die set-up includes the flanging ring, the pad, and the punch. The draw die set draws a blank and the flange die set forms a flange on the blank in two separate operations using the same die parts in the two operations. A method is disclosed for making a formed and flanged part that begins by drawing a blank held by a pad, a flanging ring and a binder ring against a punch in a press to form a drawn blank. The drawn blank is then laser trimmed to form a trimmed/drawn blank. The trimmed/drawn blank is then clamped between the pad and the punch while the flange forming ring forms a flange into a flange forming groove.
