Definitions

  • the invention relates to the technical field of seamless assembly of sheets.
  • the invention relates, more particularly, to the assembly of sheets by crimping.
  • crimping is meant a mechanical assembly in which one of the members at least is permanently deformed locally.
  • the crimping allows the unusual assembly of various strong materials such as plastic, leather, glass, wood, copper alloy, alloy aluminum.
  • the invention relates more particularly, but not exclusively, assembly by crimping of metal or metal alloy sheets.
  • Document FR-A-2,371,252 describes a process for assembling two parts which are in contact with a flat or slightly curved surface, at least one of these parts being a plate or a sheet of ductile material such as a metal.
  • a bore is provided on a part. at two successive diameters, the smallest diameter being on the side of contact with the plate or sheet to be joined to said part, this plate or sheet being provided with a bore of diameter less than the smallest of the diameters of the bore of the part.
  • the metal is pushed back located in the vicinity of the bore of the plate or sheet inside the bore of the part to be fixed, at least up to the wide part of this bore.
  • the immobilization of the washer is obtained by the discharge of the metal from the washer in the bore of the sheet.
  • a first object of the invention is to provide a method of assembly by crimping, of the buttoning type, leading to no drop in resistance to the tearing of the two assembled parts, when this assembly was carried out in presence of an axis fault.
  • a second object of the invention is to provide a method of assembling two sheets which does not require additional parts and allows, with a number reduced operations, to obtain a precise fixation of two parts, one with respect to the other ensuring that the fixing system itself accepts play necessary for the precise positioning of the two parts to be assembled, without the fixation has to suffer in its result from a low resistance to resistance to tearing or a mediocre appearance.
  • This Figure 1 is a partial sectional view of a first piece 1 of metal or metallic alloy.
  • This first part 1 comprises a joggle 2 of axis 3.
  • the plane of Figure 1 is defined by a first direction D1, called longitudinal, substantially parallel to axis 3 and a second direction D2.
  • the first part 1 has a substantially planar upper face parallel to a lower face 1b.
  • the upper face and / or the underside of the first part has slight and regular curvatures.
  • the groove 2 is of revolution by relative to axis 3 substantially perpendicular to the mean extension plane of the first room 1.
  • this routing 2 is oblong.
  • the height h2 of the run 2 is defined as the distance between the face lower 1b of the first part 1 and the extreme free transverse edge 4 of the plunge 2.
  • the internal annular face 5 of the run 2 is substantially cylindrical with an axis 3, in the embodiment shown, and defined an internal diameter of D2i jog.
  • the external annular face 6 of the run 2 is substantially cylindrical with axis 3, in the embodiment shown, and defined a diameter D2e external routing.
  • the difference D2e-D2i between the external and internal diameter of the run corresponds to twice the radial thickness e2 of the run 2, less than the thickness e1 of the first part 1, as measured in the vicinity of the run 2.
  • a second part 7, seen in section in FIG. 2, is provided with a hole lamé 8 of axis 9 substantially perpendicular to the main extension plane of this second room 7.
  • the plane of Figure 2 is defined by directions D1 and D2, the first direction D1 being substantially parallel to axis 9.
  • the second part 7 has a substantially planar upper face 7a parallel to a lower face 7b.
  • the upper face and / or the underside of the second part have slight curvatures and regular.
  • the bored hole 8 has a first, upper, annular section of axis 9, of small diameter d8 extending over a height h8s.
  • the cut hole has a second, lower, annular section of axis 9 of large diameter D8, extending over a height h8i.
  • the thickness e7 of the second part 7 is substantially equal to the sum h8s + h8i, at least in the vicinity of the hole 8.
  • this annular gap 12 is filled by the deformation of the material forming the lower end portion of the run 2.
  • FIGS. 3 and 4 the axes 3, 9 of the bore 2 and of the cut hole 8 are shown aligned.
  • the method according to the invention makes it possible to avoid such drawbacks.
  • the axis of the centering device is held in a reference position.
  • the centralizer entering the run 2 allows the movement of the axis 3 of this routing 2 in its planned positioning clearance.
  • the collar 13 of the joggle 2 is then folded back into the counterbore so as not to exceed the diameter of this counterbore, even with a maximum clearance position between the first and the second room.
  • the fixing is then in the form of a folded-down collar without excess thickness or burr with a calibrated bore with an icy appearance, the two surfaces of the assembled parts having a flatness at 5/100 th of a millimeter.
  • the method can be implemented for parts 1, 7 obtained by stamping on a press for which the dimensions have a repeatability of + -0.05 mm.
  • the differences between the axes 3, 9 of the two parts 1, 7 to be assembled can be around +/- 0.10 mm.
  • Such a deviation ⁇ is represented in part a of FIG. 5.
  • the lack or the excess material resulting from the lack of focus is passed on by a lack of concentricity of the outside diameter of the collar folded back in the counterbore of the second Exhibit 7.
  • the routing is dimensioned to allow accommodation of the game positioning of the two parts 1, 7, this accommodation being obtained by the lack of concentricity of the outside diameter of the folded collar relative to the diameter D8, without creation of excess thickness or burrs.
  • the centering device can be kept in a predetermined corresponding position for example to the dimensions imposed for the assembly obtained by crimping the two parts 1.7, these dimensions thus being independent of the conditions of crimping.
  • a drilling 2 for obtaining after fixing of a second part 7 of a hole with an internal diameter of 12.1 mm +/- 0.05.
  • Routing 2 has an internal diameter D2i of 11.90 mm, a diameter outside D2e of 14.50 mm and extends over a height h2 of 3.50 mm.
  • the routing collar 13 is then folded back into the counterbore.
