Design of Compound Die for Flange Drawing Parts

Abstract

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.

The Design of Compound Die for the Drawing Parts with Holes in Flange

“…As showed in Figure .1, the flange cylindrical parts are often seen in machinery manufacturing and industrial production and generally produced by stamping method [5] . This part is made of steel NO.10 and 1mm in thickness; the diameter of the part is 130mm and the flange is 130mm; there is a 10mm hole at the bottom of the part and at the flange there are two 8mm holes.…”
