Abstract

PURPOSE: To contrive the reduction of process and cost, by forming plural number of louvers of such type as triangle, fan, trapezoid, etc., and by calking two or more sheets of raw material.
CONSTITUTION: The cylindrical punch 6, which is provided with movable fan type protuberance 9, is brought down by the jig; hereby, the punch 6 breaks through the overlapped two sheets 13, 14, of raw material, and the fan type louver 15 is formed; this louver 15 is then pressed by the support pin 11 which has the conical trapezoid type tip 12; and the calking work is finished. By calking depending on this fan type louver 15, the louvered length of the cut part 16 in the ousdide circumference enters into the lower side of the fan type clipped part, and becomes longer than the root length of the fan, so that the louver can not be pulled out upside; hereby, the calking becomes perfect. According to this method, the burring and boring processes for the raw material 13, 14, can be omitted, so that the reduction of process and cost are realized
