Definitions

  • the invention relates to rebated connections on circumferential, superimposed sheet metal flanges, in particular for sheet metal housings composed of deep-drawn shells, according to the preamble of claim 1.
  • folded connections are also known and customary for connecting metal sheets. While the first three are always positive and non-positive connections, folded connections can also be made without a positive connection.
  • the sheets which are, for example, the flanges of housings composed of deep-drawn shells, are placed on top of one another in such a way that one sheet edge protrudes over the other.
  • the protruding sheet edge is then bent over the shorter edge area. With this connection, the two sheet metal parts can move against each other.
  • L-fold is primarily known as a fold connection with a frictional connection.
  • the two sheets lie on top of one another with flange edges of different widths.
  • the end of the narrower flange edge is bent vertically out of the sheet metal plane.
  • the end of the wider edge area is then bent around the narrower edge area. This connection can absorb forces in two mutually perpendicular planes.
  • the present invention is based on the object of specifying a rebated connection which readily enables an always exact dimensional accuracy and an increased tightness of the finished sheet metal connection.
  • This construction has the advantage that the two sheets and in particular the sheet with the wider flange edge, which is bent around the narrower flange edge bent perpendicularly from the flange or sheet plane, are now secured against displacements in the sheet or flange plane.
  • the finished housing therefore always has the same shapes and dimensions. It was also found that the finished flange connection is not only more stable, but also considerably more gas-tight than with the conventional L-fold.
  • the figures each show a section of a cross section through the flange area of a sheet metal housing made from two deep-drawn shells 1, 1 ', 2, 2'. Both shells 1, 1 ', 2, 2' each have a flange edge 5, 6 pointing outwards in the flange plane 7, the narrower flange edge 5 of the upper shell 1 being bent perpendicularly against the flange plane 7 and the wider flange edge 6 around the upstanding end the narrower flange edge 5 is bent around, as is known from the L-fold.
  • a step 3 is formed in both flanges 5, 6, which is directed in the opposite direction to the raised, narrower flange edge 5. This creates a longitudinal groove 4. This takes up the end of the wider flange edge 6, whereby the fold connection is additionally mechanically protected.
  • the figures also show a section of a lower tool or die 8 used in the manufacture of the fold connection.
  • This has a raised shoulder 9 in the area of step 3. Thanks to shoulder 9 and step 3, the wider flange edge 6 of the lower housing shell 2 is against displacement in the flange plane 7 100 percent secured so that the two half-shells 1, 1, 2, 2 'are exactly aligned in the finished sheet metal housing.
  • the seam connection overall increased repeatability and gas tightness.
