Abstract

PURPOSE: To efficiently manufacture a reflective umbrella by cutting a light metal flat plate into the form of the umbrella developed after which the cut plate is bent, worked, and formed.
CONSTITUTION: A process of manufacturing a reflective umbrella is shown by aWh. Guide holes 2, 3 are made in aluminum plate 1, and then plate 1 is passed through the processes of both side cuttings 4, 5, boring 8, both side cuttings 9, 10, boring 11, deformed borings 12, 13, deformed borings 14, 15, bendings 16, 17, cutting 19 and bendings 20, 21 on the basis of guide holes 2, 3 made in the first process a. Thus, the finished product shown by the drawing can be manufactured efficiently.
