Abstract

PURPOSE: To facilitate forming of fin using conventional fin press die by making coining on the basal part simultaneously with bulging, and making the thickness of the part thin.
CONSTITUTION: An Al blank is bulged and drawn, and the basal part 3 of the bulged hemispherical blank 2 is bulged an drawn. At the same time, coining is executed to make the thickness of this part smaller than original thickness and the section is made to a hatlike form 4. Next, the top part 5 is removed by punch burring and formed to a collarlike form 6. Further, the upper rim of the collar 6 is reflared at 8 to form a fin 7. By the above, forming of a fin can be made easily using an Al or Al alloy blank that has hardness above seminard grade.
