Abstract
PURPOSE: To accomplish mass-production of exhaust pipes for silencer, by pressing groovelike recesses continuously in a long band steel plate in which small apertures having a required area are formed along its length to have a required width, and then coupling each two of the elements having the groovelike recesses.
CONSTITUTION: Band steel plate 11 has area formed with many small apertures 10 at a predetermined pitch and remaining areas having no such apertures. After forming such apertures 10 in the plate 11, it is sent to a press, the male die and the female die of which have a shape conforming to one half of a exhaust pipe split longitudinally into two equal parts. After forming groovelike recesses consisting of a large-diameter portion 3, tapered portion 2 and porous portion 4 at a time by means of a press, they are cut into the form of one half of the exhaust pipe to be manufactured. Therefore, the porous portions 4 are formed with flanges 12 and the large-diameter portions 3 are coupled together at mating portions 13. Further, the porous portions 4 are coupled together by way of spot welding after they are joined together at their flanges 12.
