  • At least one sole is made of steel with yield strength greater than 400 Mpa or aluminum with a limit elasticity greater than 200 Mpa.
  • the two soles are made of the same metal, possibly with different thicknesses, or in different metals, a first sole being made of a metal having a yield strength / breaking load ratio which is lower or higher than that of the metal making the other sole.
  • the beam structure comprises at least two essentially parallel soles connected between they by at least two souls also essentially parallels where the soles and the souls are made in metallic materials distinct by their nature, their mechanical properties or their thickness.
  • the invention also relates to a method of assembling components of a beam structure, as described above, characterized in that the assembly is carried out of at least two components to form a section of joining by a fusion joining process such as spot welding.
  • the assembly of at least minus two components to form a junction section is achieved by an assembly process by rivets, by simple crimping, by clinching.
  • the assembly of at least two constituent elements in view to form a junction section is achieved by a assembly process by hem crimping.
  • the ratio of the radius to the sum of the thicknesses of the various constituent elements along the joining section is included, from preferably between 2 and 10.
  • the ratio of the difference between the radius and the thickness of the element the outermost with the thickness of the element the most interior is preferably greater than 2 and the ratio the thickness of the two elements is preferably less to 4.
  • the assembly process presented by the invention provides a beam structure having a non-constant section and varying according to the height and / or width.
  • the assembly operations mechanical are made using a press.
  • the assembly by crimping per hem is produced in the same press cycle.

  • Figure 2 shows an example of execution of a particular soul used for a structure of beam according to the present invention, and in particular such as shown in Figure 1.

  • Figure 5 shows all of the tools intended to carry out an assembly by hem to the press as shown in Figure 4.
  • Figure 6 shows a sectional view of a beam element with variable section along line A-A 'and along line B-B '.
  • Figure 7 shows a block diagram of a tool operating by press in order to allow the realization of a beam structure according to the present invention, and in particular as shown in the figure 1.
  • the proposed solution is based on the use at least two metallic materials, in sheet or in sheet metal, distinct by their nature, their properties mechanical or their thickness in order to achieve a more elaborate structure. More specifically, this invention proposes to use steels with high mechanical properties in combination with steels more ductile to achieve a beam structure of optimized weight and possibly presenting a evolutionary section according to certain embodiments. he it is therefore a composite structure made from at least two distinct metallic materials by the nature, mechanical properties or by thickness.
  • the stress level maximum is reached at the soles.
  • the material chosen to make these soles must therefore have a yield point as high as possible. It is essentially the section of the sole that determines the moment of inertia: we must therefore be able to adjust width and thickness to optimize strength and size.
  • the soles can optionally be made in two metallic materials distinct at least in nature, mechanical properties or thickness, for example for optimize the weight of the beam according to stresses or space constraints.
  • the core that connects the soles is subjected to the bending but above all is the seat of constraints of shear and can be locally stressed in compression. To optimize the weight, you must be able to use a minimum metal thickness. This can be achieved by giving souls a geometry improving their buckling resistance. This implies that the metal used for souls must have ductility better than the metal used for the soles, i.e. a yield strength / breaking load ratio lower, and certainly less than 0.9.
  • the soles 1 and 1 ' are produced in a sheet or sheet metal with a limit of very high elasticity, a steel weakly alloyed with carbon, for example.
  • the elastic limit is chosen as high as possible.
  • steel it will be located in a range of 400 to 1500 MPa, for aluminum between 200 and 800 MPa: the metal can then have a very limited formatting capacity.
  • Cores 2 and 2 ' are made of metal in sheet or sheet with better ductility than the metal of the soles, so a level of relationship yield strength on substantially breaking load lower, and in any case less than 0.9.
  • Souls 2 and 2 ' are not necessarily planar but present by example a ripple 3.
  • a typical example of realization of souls is shown in Figure 2. The purpose of this ripple is to strengthen the buckling resistance of cores: one can thus significantly reduce their thickness.
  • the soles and the souls are joined to the level of the junction zones 4 by a welding process or mechanical assembly.
  • welding processes we may consider for example spot welding, the seam welding, laser welding, welding by diffusion, soldering.
  • mechanical assembly processes like assembly by rivets, assembly without rivet by local deformation known as clinching, the crimping.
  • a particularly interesting variant of assembly method is hem assembly.
  • This guy assembly applied for example for boxes of canned can be made by press or by tools rotary type knobs.
  • a typical example of this type assembly applied to the present invention is shown in Figure 4.
  • a hem 7 is made at of each junction zone sole 1 / core 2.
  • the advantage of this type of assembly is twofold: by its geometry, it helps strengthen the structure and it can be achieved using very productive processes like a press stamping or profiling machine.
  • Figure 5 shows an example of tooling allowing to carry out this assembly by hem to the hurry.
  • the soles 1 and the cores 2 are prepared for of the hem formation as indicated in 9: they receive a preform which initiates the hem.
  • the pieces are then placed in the tool which is composed of the elements mobile 10, 10 'and 11, 11'. These elements are therefore first apart, horizontally for 11 and 11 ', vertically for 10 and 10 '. Parts 1 and 1 'are deposited on 11 and 11' respectively and maintained by means not shown, a magnetic system for example.
  • the cores 2 and 2 ' are deposited on the mobile elements 10 and 10 'which match the shape of the ripple 3.
  • Tools 8 are then moved simultaneously or successively to form the hem and be in the position indicated by 8 ', 8 "and 8".
  • This type of tool can be mounted on a press, the elements 11 being moved by a cam system generating horizontal movement when closing of the press, elements 10, 8 and 8 'being put in action by the upper slide of the press: 10 is spring-mounted and its stroke is limited by a stop not shown, 8 and 8 'are directly attached to the press slide.
  • Figure 6 shows a view of an element of beam with variable section: section A-A 'is more wide and taller than section B-B '.
  • this type of hem assembly can also be performed using knurled tools according to methods known from elsewhere.
  • the system can then be integrated into a line profiling.
  • Figure 7 shows the block diagram of such assembly by rollers.
  • Two rollers 13 and 13 ' b-b 'vertical axes hold the soles laterally, the hem being produced by two rollers 12, 12 'of horizontal a-a' axes.
  • several rolls of pebbles like described in Figure 7 can be used to achieve hem gradually.
