Definitions

  • the invention relates to a method for joining at least two areas stacked sheet metal parts.
  • the object of the invention is a method for joining at least two to create sheet metal parts lying flat on one another, in which the joining with comparatively low assembly force (e.g. hand force or hammer blow) is producible and / or can be detached again without the sheet metal parts to be damaged.
  • comparatively low assembly force e.g. hand force or hammer blow
  • the subclaims relate to expedient developments of the invention, which make it possible, for example, to limit the joined sheets to move parallel to each other.
  • the first can be seen in the sectional views of FIGS. 1 and 2 Sheet metal part 10, from which out of the sheet metal plane of the first sheet metal part 10 Nipple 12 was enforced.
  • the stamp used was rectangular Cross-section, whereby stamps with other, e.g. round or oval cross sections are conceivable. Between the stamp and an anvil the bottom 14 of the nipple 12 was pressed, so that two each other opposite sides formed ridges 16, i.e. on the nipple wall beads are formed. The formation of a bead is included sufficient.
  • the bead 16 is preferably surrounded by a circumferential ring educated. As can be seen in Fig.
  • a thin web 18 remained between the beads 16 and sheet metal part 10; but this is not mandatory since the nipple remains connected to the sheet metal part via tabs 20, even if the sheet is cut above the beads.
  • the embodiment is the joining on the side of the sheet metal part 10 however gas and liquid tight.
  • FIG. 3 and 4 show the second sheet metal part 30, which by means of a corresponding Tool set cut along two parallel lines was, after which the material web 32 between them from the sheet plane of the second sheet metal part 30 was enforced. That is how it came about Cut lines or breakthrough edges 34. It should be noted that it too is within the scope of the invention, the sheet metal part 30 simply with an opening to be provided, ie to cut away the web 32, the cutting lines or breakthrough edges are not necessarily parallel and / or linear have to.
  • the dimensions of the deformations of both sheet metal parts 10, 30 are chosen so that the width of the nipple between its beads 16 is larger than the width of the cutout between the edges 34, but only so much that both sheet metal parts in the joining area under elastic deformation can be snapped together, cf. Fig. 5 16 beads the edges 34.
  • the extension of the detail from the second Sheet metal part 30 in the direction transverse to the beads 16 may be larger than that of Nipples 12, so that there are free spaces 40 and the two sheet metal parts are limited displaceable to each other in this direction.
  • At least one of the sheet metal parts to be joined can be in the area of the joint this from a non-metallic material, in particular Plastic.
  • a surface can have at least one of the sheet metal parts to be joined be glued before joining.
