Definitions

  • the invention relates to a method for producing a Absorption silencer for motor vehicles in half-shell construction with one arranged in a cavity of the half-shells Soundproofing material in the form of glass wool or the like, with the silencer body completely prefabricated and assembled and the glass wool into the prefabricated, assembled half shells subsequently from the outside through one or more trained filling openings in the Cavity is introduced, and the filling openings after a Filling can be closed again.
  • absorption silencers have annular gaps and / or chambers in which the sound absorbing material, in particular glass wool, is arranged.
  • the soundproofing material is around the semi-finished product of an inner shell or Inner tube attached before the outer shell is assembled and with the inner shell or the inner tube, e.g. about one Fold or a weld, is connected.
  • the order of the incompatible flexible sound absorption material to the designated places or in the designated places Chamber of a silencer and the subsequent assembly of the silencer body are comparatively tedious and expensive.
  • the silencer body completely prefabricated and the soundproofing material subsequently introduced through filling openings.
  • the silencer body can be wrapped or half-shell be provided. With a silencer body in half-shell construction with a folded fold between the The filling openings are in the shell of a half-shell Half shell or on the front of the silencer body.
  • the object of the invention is a simplified method for Production of an absorption silencer in half-shell construction with the help of simple means to put and accordingly a silencer on simple Way to create.
  • An absorption silencer manufactured by the method according to the invention is characterized by the characteristics of the Claim 5.
  • the muffler is advantageously further developed by the Features of claims 6 and 7.
  • the edges of the shell are welded in particular by laser.
  • the glass wool is expediently under pressure or suction through the filling opening (s), preferably through Blow in or by suction.
  • the manufacturing method according to the invention is also suitable for unpacked glass wool that passes through the filling opening (s) is introduced.
  • An absorption silencer manufactured according to the aforementioned process in half-shell construction includes prefabricated Half shells with flat shell edges, which indentations have, at least in composite half shells form a filling opening, which after filling can be pressed flat.
  • the flat edges of the bowls put together Half-shells are laser-welded in particular by means of a laser seam, the one pressed flat after filling Filling opening preferably by means of a further laser seam is also laser welded.
  • Unpacked glass wool can also be processed in the silencer body or be introduced.
  • the invention makes the manufacture of an absorption silencer simplified in half-shell construction, as - in contrast to the known method mentioned at the beginning -
  • the filling openings in the separation or connection area of the two half-shells previously attached in particular can be imprinted, and half of one Entry opening through an indentation or gutter that is assembled with a preferably uniformly shaped counter-indentation or counter gutter a circumferentially closed
  • the complete filling opening which preferably can have a round cross-section. Every indentation is in the otherwise flat, not folded edge of everyone Half-shell integrated and easily again without material breakage can be reshaped if it is filled with glass wool the filler opening into the interior of the silencer more is needed.
  • the half-shells with the inserted Laser welded internal parts Then it is embossed
  • the glass wool is blown through the openings in the edge of the bowl. Then the openings are pressed and welded.
  • the Openings are co-embossed when the shell is made. It Unwrapped glass wool can be processed. Disorders due to fiber residues in the welding area do not occur.
  • Figures 1 to 3 comprises an absorption silencer a silencer body in half-shell construction.
  • the silencer has an upper half shell 1 and a lower half-shell 2. There are more inside silencer parts of no further interest here.
  • Both the upper half-shell 1 and the lower half-shell 2 have flat shell edges 4 and 5, the composite
  • the condition of the two half-shells lies well on top of each other and are welded, for example by means of laser seam 11.
  • the in the flat shell edges 3, 4 of the prefabricated Half-shells 1, 2 embossed indentations 5, 6 form composite half-shells 1, 2 at least one filling opening 3 out, which after filling can be pressed flat and is also weldable, for example by means of another Laser seam 12.
  • the welding of the shell edges 4, 5 takes place in particular preferably by laser.
  • the glass wool 10 is under pressure or suction through the filling opening (s) introduced, preferably blown or sucked.
  • Unpacked glass wool can also pass through the filling openings 3 10 are introduced.
