Abstract (en)

[origin: EP1036607A2] An apparatus and method for forming a cup (10) having a profiled bottom generally includes a draw die (20) disposed at a first level of a double acting press. The draw die (20) cooperates with a draw pad (22) and a cut edge (24) to form and hold a blank (28) formed from a sheet of material (M). A punch assembly (30) is configured to travel through the draw die (20), thereby drawing the blank (28) over the draw die (20) into a cup (60). The punch assembly (30) transports the cup (60) to a second level of the press where it bottoms out on a die core (50) and a ring pad (51). One element of the punch assembly (30) continues to move beyond the second level of the press, thereby drawing a portion of the cup (60) over the die core (50) and profiling the bottom of the cup (60). The profiled cup (10) is then returned to the second level of the press where it is removed from the punch assembly (30) and transferred. The bottom profile insures that the cup will retain its shape during the transfer operation. <IMAGE>
