Abstract
PURPOSE: Plate hole is curvedly bent at peripheral portion, in two steps, to form a plate fin having a cylindrical portion and a fin portion. A plurality of the plate fin inserted in multistage facilitates equipitched fin arrangement.
CONSTITUTION: A first 6, a second 7 and a third 8 lower molds are arranged so that upper level of each mold are aligned in a straight line, on which a plate 11 to be fabricated is placed. A punch 1 is lowered A1 to make a hole on the plate 11 by shearing with small portion 3 of the punch 1 and the mold 6. The mold 6 is moved down a1 and the punch 1 is further lowered a2 to form curved bend 12A on the plate 11 by using a first expanded portion 4 and the mold 7. The mold 7 is then moved down a2 and the punch 1 is further lowered a2 to form a cylindrical portion 12B and a fin 12C on the plate 11 by using a second expanded portion 4 and the mold 8. At the same time, the curved bend 12A is escaped into an annular recess 9 to become parallel to the fin portion 12. The molded plate fin 12 is removed by moving the punch 1 upward, moving the mold 8A, 8B to the left and right, respectively.
