Definitions

  • the present invention relates to a sheet-metal component, in particular a silencer base, with at least one passage opening for a tubular component, in particular for an exhaust pipe, according to the preamble of claim 1.
  • a tubular member In a variety of applications, it is necessary to insert and connect a tubular member through a through hole of a sheet-like member.
  • Such an application is for example a muffler bottom of an exhaust system for an internal combustion engine, in particular in a motor vehicle, which is penetrated by an exhaust pipe.
  • a mechanical load in the region of the connection of the tubular component to the sheet-like component may occur, wherein force peaks may cause a peripheral edge of the through opening to tear.
  • the present invention is concerned with the problem for a sheet-metal component of the generic type a specify improved embodiment, which is characterized in particular by a better shelf life.
  • the invention is based on the general idea, in the case of a sheet-metal component having a passage opening for a tubular component, in an area adjoining the passage opening, to provide at least one slot penetrating the sheet-like component, which extends in the circumferential direction of the passage opening or tangentially to the same.
  • One or more such slots cause the operation of the exhaust system or when heating the tubular member an improved force into the sheet-like component and lead to a serpentine flow of force around the arranged in the sheet-metal component slots around. Due to the serpentine power flow curve, the force is introduced on a significantly longer path in the sheet-metal component, so that it is able to absorb the force introduced in the elastic region and thus without deformation or without damage.
  • the at least one slot penetrating the sheet-like component can be produced by a suitable cutting operation with or without material removal.
  • Such a punching process can be realized without cutting, whereby the tool used in this case can achieve a long service life and thereby reduces the manufacturing cost of the sheet-metal component.
  • the slot has at each end a rounding which enlarges the slot width, or the longitudinal end-side end sections of the slot are bent semicircularly. Both variants cause a favorable flow of force in the longitudinal end region of the slot and thereby reduce the risk of tearing the slot end.
  • the described embodiment of the longitudinal end regions of the slots thus voltage peaks can be better absorbed while the life of the sheet-metal component can be increased.
  • At least two slots have different lengths.
  • the longitudinal extent of the slots can thereby individually to the occurring or expected force flow be adapted, whereby the sheet-like component can be aligned particularly well in the production of the loads occurring in the subsequent operating state already in the production.
  • a plurality of slots are arranged along a plurality of radially spaced-apart circles. These circles do not necessarily have the same center and cause a favorable force flow of the force to be introduced in particular in a chosen in the manner of a staggered association arrangement of the slots along the circles.
  • the force flow is forced to a serpentine line, whereby the distance traveled extends. This extended force introduction path causes the material to be able to absorb the introduced force in the elastic region, so that there are no, in particular permanent, plastic deformations during operation.
  • a sheet-metal component 1 has at least one passage opening 2, in this case a total of three passage openings 2, 2 ', 2 ", whereby at least one passage opening 2 can guide a tubular component, in particular an exhaust pipe, not shown
  • the sheet-like component 1 may be designed, for example, as a silencer base and be part of a muffler of an exhaust system for an internal combustion engine, in particular in a motor vehicle, which is not shown in the remainder of the drawing 2 adjacent area a plurality of the sheet-shaped member 1 penetrating slots 3, which is substantially in the circumferential direction of or tangential to the passage opening 2 run.
  • the slots 3 can have a curved or a straight course.
  • the sheet-like component further, the sheet-like member 1 penetrating openings 4, which are arranged according to the Fig. 1 grid-shaped offset from each other.
  • the openings 4 are, however, purely exemplary, so that sheet metal-shaped components 1 according to FIG. 2 should also be included in the invention, which have no additional openings 4.
  • the slots 3 can have, for example, a fillet-enlarging fillet 5 (cf., FIG. 2), which effect an improved force flow within the sheet-metal component 1.
  • a fillet-enlarging fillet 5 (cf., FIG. 2), which effect an improved force flow within the sheet-metal component 1.
  • the longitudinal end-side end portions of the slots 3 may also be bent in a semicircle, which causes the same effect.
  • the fillets 5 and the bent end portions are preferably arranged concave to each other and are radially from the respective slot 3 to the outside.
  • the slots 3 are arranged along a plurality of radially spaced circles 6, which either, as shown in Fig. 1, do not have a common center, or, as shown in Fig. 2, are arranged concentrically to each other. Regardless of the arrangement of the circles 6 to each other, the slots 3 are preferably arranged in a kind of offset association to each other along the radially spaced-apart circles 6. Such a staggered association is for example from the field of masonry known and causes that in any layer (here circles 6) butt joints between individual slots 3 are continuous.
  • the tubular, not shown, component penetrates at least the through hole 2 and is in the region of the through hole 2 fixedly connected to the sheet-metal component 1, for example by welding or soldering.
  • this can lead to a heating of the tubular component, so that it expands in the circumferential direction.
  • Such expansion causes a force acting in the circumferential direction on an edge 7 of the through hole 2, which would lead to tearing of the edge 7 in the worst case.
  • the slits 3 are provided in the region adjacent to the through-hole 2.
  • the slots 3 thereby cause a deflection of the power flow, whereby the path to the introduction of force is extended, preferably such that the sheet-shaped member 1 can record the example entered due to the thermal expansion force in the elastic range.
  • the above-described arrangement of the slots 3 in the manner of a staggered association along the radially spaced circles 6 causes a forced, serpentine course of the power flow between the slots 3 and thereby extends the force introduction path in a particularly advantageous manner.
  • the arrangement of the slots 3 along the radially spaced-apart circles 6 is to be understood purely as an example, so that, for example, an arrangement of the Slits 3 along circumferentially bent rays is conceivable.
  • the slots 3 may have different lengths and thereby be particularly well adapted to the expected force input. It is also conceivable that the slots 3 are arranged only on a limiting circumferential segment around the passage opening 2, as shown for example in Fig. 1, or fully circumferentially around the passage opening 2 around, as shown in Fig. 2.
  • the sheet-metal component 1 may be designed as a muffler bottom as described above and thereby form part of a muffler, for example for an exhaust system of a motor vehicle.
  • a silencer floor for example, has the task of a partition, which separates two rooms in the silencer from each other.
  • one of the rooms may be an absorption space that may be filled with a sound-absorbing substance or with absorption material.
  • the sheet-metal component 1 is attached in this embodiment to a housing, not shown, of the muffler, in particular welded.
  • the sheet-like component 1 may be formed from a plastic or from metal, in particular from sheet metal.
  • sheet-like should in this case only be understood as meaning that, in the case of a Cartesian coordinate system, the component 1 has a significantly smaller thickness than its extension in the longitudinal direction. or width direction.
  • the sheet-like component 1 can basically have an arbitrary, three-dimensional course and does not have to extend in one plane.
