Design of Compound Die for Flange Drawing Parts
At present, the flange drawing part with bottom hole is produced by at least 2 sets of dies and not qualifies for modern manufacture concept. In this paper, a compound die is designed which the flange drawing part can be blanked, drew, punched and trimmed in the same forming-position. The die is made of tow convex and concave dies, one drawing female die, one punching die, one blanking female die and one trimming punch. One of the convex and concave is used to blanking, the blank is drew by drawing female die and the other convex and concave, the punching die is applied to punch the bottom hole, the edge of blank is cut by trimming punch. Beside, the key design points and working process of the compound die were discussed as well.
