Definitions

  • the present invention relates to a method for producing an insulating part according to the preamble of claim 1, and to an insulating part produced therewith according to the preamble of claim 6.
  • Such insulation parts are preferably used in the automotive sector, where they are used, for example, between the hotter catalyst and the vehicle floor.
  • the WO 91/10560 describes a heat shield with a foil package which comprises heat-conducting zones, so-called heat sinks, and heat-insulating zones.
  • the individual films of the film package have impressions or nubs, which cause the stacked films are spaced apart.
  • the individual films can be hermetically sealed together, thus enabling the inclusion of a gas, eg xenon.
  • the individual films are perforated to improve the acoustic effectiveness.
  • the edge regions of these film packages are compressed in practice without significant pressure force, cut and then crimped, heat-sealed or mechanically connected.
  • an insulating part which comprises a stack of a plurality of thin metallic sheets, between which sheets a metallic knitted fabric or an expanded metal-like spacer is used.
  • acoustic effectiveness of these foil packages depends essentially on the perforation, the choice of material and the mutual distance of the individual foils.
  • suitable films preferably of aluminum, are guided via corresponding spiked rollers and / or nubbed rollers.
  • a desired by the acoustic professional change the knobbly shape or density, the perforation density or the size of the individual perforations, makes costly tool changes required.
  • this method the perforation density and the air flow resistance generated by such a perforation can be changed in a simple and cost-effective manner.
  • This object is achieved according to the invention by a method having the features of claim 1, and in particular by a method for producing a sound-absorbing insulating part with at least two metallic sheets, which may have the form of a film or a thin sheet.
  • the material of at least one metallic sheet is knopped in a method step and in a further method step this knotted sheet is connected to at least one second metallic sheet.
  • the elastic limit of the sheet material is exceeded in such a way that hairline cracks resp. Form fissures.
  • thin sheets can be fissured just as well as thick foil, or sheets in the form of expanded metal used. Furthermore, it is particularly advantageous if aluminum is used as the material for these sheets.
  • a particularly preferred embodiment of the inventive method provides that the individual metallic layers, in particular films resp. Leaves to be cold-welded together.
  • Cold welding is understood in the following to mean a metallurgical bond which comes about through a plastic deformation of two or more adjacent foils or sheets, in which deformation the metallic material of adjacent sheets cohesively bonds.
  • a connection can be achieved if adjacent metal sheets are compressed, for example, by about 75%.
  • an object of the invention to provide an insulating part, in particular a heat shield with improved and easily optimizable acoustic effectiveness.
  • a sound-absorbing insulating part with the features of claim 6, and in particular by a sound-absorbing heat shield, which comprises at least two metallic sheets, wherein the at least one metallic sheet has a plurality of nubs and / or fissures and with the at least second Sheet is connected and deformed into a molded insulating part. It is of particular advantage if these metallic blades are made of aluminum.
  • the inventive method proves to be surprisingly simple and leads to sound-absorbing insulation parts with a surprisingly good sound absorption.
  • a sheet-like metal foil 12 is drawn off continuously from a roll 13 and passed through a roll device 14 for nip.
  • This roller device 14 essentially comprises a nub roller 15 and a counter-roller 16, which can be coated with an elastic material or with a mesh-like structure cooperating with the nub roller 15.
  • This counter-roller 16 presses the film 12 against the nubs of the nub roller 15.
  • the nubs of the nub roller 15 and the counter-roller 16 are matched to one another such that the film 12 partially ruptures in the nip in this roller device 14.
  • the brittleness or elasticity of the sheet material to be nipped also plays a role here.
  • the thus fissured sheet 13 is then cut 19 in a known manner and stacked 20. It is understood that this method can also be designed discontinuously and the roller device 14 can be replaced by suitable press plates.
  • the fissured sheets are combined with similar or other metallic sheets and shaped in a known manner and fastened to one another.
  • the elastic limit of the metallic material of the film 12 is thus exceeded during napping in the roller device 14 such that a multiplicity of irregularly arranged fissures 4, 11 are formed.
  • these fissures 4 compared to needled perforations, the acoustic energy dissipate better and thus sound-absorbing insulation parts, in particular heat shields can be produced with improved acoustic efficiency.
  • the air flow resistance on the surface of an acoustically effective insulating part can be varied in a simple manner and adjusted so that optimum sound dissipation can be achieved for any arbitrarily shaped insulating part. This optimization or adjustment is carried out according to the invention on the number, density and length of the fissures.
  • fissures 4, 11 with different lengths can be formed.
  • a high fissure density can be achieved with shorter fissures 4 (which occur, for example, at locations of maximum drawstring, ie at the nub points 10), and a lower fissure density can be produced with longer fissures 11 extending over two or more nubs 5 ,
  • the material of the web 12 is cut into predetermined parts and stacked.
  • at least a first sheet fissured in the above manner and a second metallic sheet are superimposed and joined together by flanging, stapling, gluing or cold welding.
  • the second metallic sheet used may be a film or a sheet which may be imperforate or perforated, in particular fissured, which may be studded, ribbed or undeformed, which may be more or less rigid, have different thicknesses or in the form of an expanded metal can be used.
  • cold welding is understood to mean a metallurgical connection which results from a plastic deformation of two or more adjacent blades, in which deformation the metallic material of adjacent blades bonds in a material-locking manner.
  • a connection can be achieved if, for example, the material is compressed by about 75%.
  • the manufacturing method disclosed herein can be further automated by, for example, simultaneously withdrawing the various sheets from different rolls or stacks and then cut, shaped and / or cold-welded together.
  • FIG. 2 shows two fissured and stacked sheets 2, 3 according to the invention. These sheets have a plurality of nubs 5, which ensure that the two sheets 2, 3 are spaced from each other.
  • the fissures 4, 11 produced in the production method according to the invention lie essentially in the area of the studded crest 10, since, in the case of knobs, the stretching of the material occurs most pronounced in this area and according to the invention the elastic limit of the material is exceeded. It is understood that the number and length of the individual fissures 4, 11 can be varied by the choice of the sheet material.
  • knobs 5 are hemispherical, frustoconical, pyramidal, cuboidal or cylindrical bulges form and select their density, arrangement and size in the desired manner.
  • the inventive isolation parts have at least two leaves 2, 3, of which at least one according to the invention is fissured.
  • These sheets 2, 3 are preferably made of aluminum and may be unperforated or perforated, in particular fissured, studded, ribbed or undeformed, more or less rigid, have different thicknesses or be in the form of an expanded metal.
  • these sheets can be supplemented with carrier plates of known type or with metallic insulating fabrics, nonwovens.
