Definitions

  • the present invention relates, in general, a crimped assembly of three parts with overlapping two of these parts for their docking, these two parts being supported by a third, the assembly requiring a crimping of two parts together.
  • the present invention relates to an assembly of three sheets with crimping of this assembly. This is preferably intended to be fixed to the bodywork of a motor vehicle, which requires a good seal and good appearance of the assembly.
  • the edge of a first piece to be folded over that of the second piece is folded perpendicularly, in a first step, and then folded completely, in a second step, being applied against the edge of the other piece then pinched against it.
  • This crimping is made difficult in the case of the present invention, when this crimping is operated with three pieces, two pieces to dock and overlapping at least for a certain length and a support piece. There is a risk of moving these parts relative to each other and the pinching is complicated by the fact that it is necessary to pinch several thicknesses of parts against each other.
  • the problem of the present invention is to achieve the docking of two parts supported by a third in a simple manner with a current tool, the docking thus produced having a seal and a satisfactory external appearance.
  • the subject of the invention is an assembly of three parts, a first part of which has a front end received under the front end opposite a second part for the overlapping approach of these two parts, each of these parts being supported by a third common part, this assembly having a crimped side side, characterized in that the first part has on its end end portion adjacent to the lateral side crimped a cutout, the lateral side crimped of the assembly born comprising at any point simultaneously the lateral edge of the first piece with that of the second.
  • the invention relates to a motor vehicle characterized in that it comprises a bodywork element comprising such an assembly of three parts.
  • the figure 1 gives an example of a docking of an assembly of two sheets 1 and 2 supported by a third 3 with an overlap zone of the two sheets. This example illustrates the state of the art.
  • the sheets 1 and 2 are supported by the sheet 3, for example by being welded to this sheet 3. These sheets 1 and 2 overlap each other in an overlap zone, the sheet 1 passing under the sheet 2.
  • a crimp assembly is then performed: it requires a crimping se2 of the sheet 1 with the sheet 3 before the overlap portion which corresponds to a two-ply crimping. It then requires in the overlapping zone of the plates 1 and 2 a crimping se3 in three thicknesses, concerning the sheets 1 and 2 and the support plate 3.
  • This solution requires the presence of a recess 4 having a certain dimension which the appearance of the assembly after docking.
  • a sealing strip 5 is introduced into the assembly and before crimping, under a portion of the sheet 1 before docking with the sheet 2, under the plates 1 and 2 in the area of their overlap and finally under a portion of the sheet 2 after overlap.
  • This sealing strip 5 extends substantially parallel to the crimped edges se2 and se3 and at a distance therefrom. In the area of the recess 4, this sealing strip 5 is closer to the edge than it is to the edges se2 and se3.
  • the figure 2 is a schematic representation of a section of the three superimposed sheets in their overlap zone during a docking made according to the state of the art.
  • the beginning of the zone of overlap Z is limited by the front side dz of the sheet 2.
  • the sheet 1 passes under the sheet 2, these two sheets 1 and 2 being supported by the sheet 3.
  • Over most of this length lz of this overlapping zone three thicknesses of sheets 1, 2 and 3 are superimposed which causes an unattractive bulge of the assembly.
  • a jogging operation is performed in this overlapping zone.
  • the overlap of the plates 1 and 2 in the overlapping zone Z comes less from the plane of the sheet 1 or the sheet 2 when they are individually supported by the sheet 3.
  • the figure 3 illustrates an embodiment of the docking of an assembly of three sheets with the docking of two of them, made in accordance with the present invention.
  • the edges of the sheets 1 and 2 intended to be crimped with the sheet 1 to form a crimped lateral side of the assembly are arranged in such a way that crimping is always done with only two sheets, either the sheet 1 with the sheet 3, or the sheet 2 with the sheet 3. This arrangement is made by cutting on these different sheets 1 and 2.
  • the front ends of the sheets will characterize the edge zones of sheets facing each other and intended to overlap.
  • cutouts are arranged on the respective end portions of the plates 1 and 2, these portions facing each other.
  • the substantially rectangular surface limited, on the one hand, by a portion of the front edge of this sheet and, on the other hand, by a portion of the edge side of this sheet, lying towards the lateral side to be crimped is removed by cutting.
  • a rectangular surface 2 ' limited, on the one hand, by a portion of the front edge of this sheet 2 disposed between and on the other hand a portion of the lateral edge of this sheet is retained while the rest of this front part is cut out.
  • This rectangular surface 2 ' has its opposite side to the sheet 1 attached to the sheet 2 and in alignment with the front edge dz of the sheet 2 under which the front end portion of the sheet 1 is housed and where begins the overlap of the two sheets 1 and 2.
  • the rectangular surface 2 'of the sheet 2 has sides of width and length less than the rectangular cut surface of the sheet 1, so that when the front end portion of the sheet 1 is introduced under the sheet 2, there remain front 3 'and side 3 "on each side of this rectangular surface opposite the sheet 1. These front 3' and side 3 '' left spaces appear sheet 3 supporting sheets 1 and 2.
  • the crimping length se2 is made with a crimp in two thicknesses which concerns the sheet metal. 1 and the support plate 3. Then, the sheet 3 appears on a short distance and there is no crimping. After that, the remaining uncut portion 2 'of the sheet 2, with a rectangular section in this figure, forms part of the crimped lateral side of the assembly and the crimping length se2' is made by crimping the free edge of this rectangular section. 2 'of the sheet 2 with the support plate 3.
  • the crimping length relates to the sheet 2 with the support plate 3 and the crimping is in two thicknesses.
  • This sealing strip 5 extends away from the crimped edge from the inside of the sheet 1 to extend towards the sheet 2 through the surface rectangular 2 '.
  • This sealing strip 5 preferably extends parallel and at a distance close to the lateral side (se2, se2 ') of the assembly before and after the overlap zone of the two parts.
  • Part 3 ' and 3' 'left uncovered by the sheet 1 or the sheet 2 are reduced in size relative to the recess made according to the state of the art.
  • Part 3 ', perpendicular to the front edge dz of the sheet and of width 13', and part 3 '' parallel to this front edge and of width 13 '', may be of the same width, there may be a recess 4 'in the part of the lateral side crimped, but this recess 4 'is smaller than the recess 4 according to the state of the art, for example more than half as large as this one.
  • the docking device makes it possible to limit the clearance between the parts to be overlapped. It also reduces the risks of tightness, by allowing a limitation of the water infiltrations as well as entries of dust, improves the perceived quality of the assembled part by limiting the recess visible by the customer.
  • the additional operation of soyage is removed by allowing to have a part of less complicated appearance and visually more robust. The removal of the soyage has the consequence of simplifying the design and focus of the seamer and decreases the cost.
