    [0060] DESCRIPTION OF A PREFERRED EMBODIMENT
    [0062] The system for manufacturing body or body subsets of the present invention is conceived for the manufacture of body or body subsets, which are made up of a floor and / or sides, which in turn are made up of a main sheet metal 2 or metal base, and also on said main sheet 2 different reinforcing pieces 4 are attached as crossbars. Said reinforcing parts 4 are joined to the main plate 2 by welding.
    [0064] As schematically represented in FIG. 1, the inventive body or body subassembly manufacturing system of the invention comprises a main stretching means 1 in at least one direction of the surface extension of the main sheet metal 2 constituting the floor and / or or sides of the body.
    [0065] The main drawing means 1 can comprise jaws, or other elements or systems known in the state of the art.
    [0067] Preferably, in the body or body subassembly manufacturing system of the present invention, the sheet metal 2 and / or the reinforcing parts 4 are made of aluminum, which means that the deformations caused by the heating and cooling of the weld on the sheet 2 will be minimized due to the internal tensile forces caused by the tensioning system.
    [0069] In this embodiment shown in FIG. 1, the plate 2 is arranged in a horizontal position.
    [0071] As can be seen in Figures 2 and 3, the system for manufacturing body sub-assemblies or bodies of the invention, to improve its performance, may also further comprise a bearing surface 5 and positioning of the main sheet metal 2. Said support surface 5 and positioned may have a convex geometry as seen in figure 2, or a concave geometry as shown in figure 3.
    [0073] The plate 2 arranged in a horizontal position is supported by the support surface 5, which is therefore arranged horizontally.
    [0075] In other preferred embodiments, the body or body sub-assembly manufacturing system of the present invention may also further comprise other additional positioning and / or stretching means 6, as can be seen in the plan view of the figure 4.
    [0077] As in the case of the main stretching means 1, the additional positioning and / or stretching means 6 may comprise jaws or other elements or systems known in the state of the art.
    [0079] The additional means for positioning and / or stretching 6 can also incorporate support and positioning elements for the sheet 2, as long as it is not necessary to tension or stretch the sheet 2, that is, when only the sheet is being stretched 2 in its longitudinal direction a transverse stretching may not be necessary, so that the additional means for positioning and / or stretching 6 can only comprise elements for supporting and positioning the sheet metal 2.
    [0081] As can be seen from the dotted or dotted arrows in the same figure 4, the additional positioning and / or stretching means 6 are enabled and arranged to stretch the main sheet metal 2 in a direction orthogonal to the direction of stretching provided from the main drawing means 1.
    [0083] In figure 5 a schematic representation of the main stretching means 1 can be seen, indicating how they act on the sheet 2 to be retained and stretched, with the action of jaws 101 and actuating pistons 102 that would move longitudinally as a whole to said stretching means 1 to cause the desired stretch.
    [0085] With the aforementioned additional stretching provided by the additional positioning and / or stretching means 6, in addition to the stretching provided by the main stretching means 1, it is possible to promote the minimization of deformations in the body or bodywork sub-assembly to be manufactured, both in longitudinal direction as transverse or vertical.
    [0087] These deformations, which appear in the current state of the art prior to the present invention, which quantitatively can oscillate in a conventional way between 5 and 30 mm for every 10 linear meters of the body or body subset, are those that decrease with the manufacturing system of sub-assemblies of bodies or bodies of the present invention.
    [0089] Although the cited numerical values may seem minimal for bodies of considerable dimensions, and in particular for subsets of commercial vehicle bodies, the tolerances allowed in the floors and / or sides for their assembly and manufacture are minimal, and therefore, these deformations can cause a problem of global adjustment of the bodywork, in the corresponding assembly lines, as well as introduce unnecessary stresses if the initial deformations are too pronounced.
    [0091] The main drawing means 1 provide the main plate 2 with a stabilizing condition, since the contraction of the material during cooling after welding introduces internal stresses that cause buckling. With this additional tension, the residual stress gradients are smoothed so that, when the part cools, the thermal expansions and contractions after the joining process of the reinforcing parts 4 do not cause deformations outside the process tolerances due to residual stresses.
    [0093] The invention also includes a method of manufacturing body or body subsets, suitable to be carried out by the system of body or body subsets manufacturing described in the same invention, and which uses some elements already mentioned in the description already made of the system of the same invention.
    [0095] As schematically represented in Figure 6, the method of manufacturing body or body subsets comprises different successive steps.
    [0097] Firstly, a positioning 10 of a main plate 2 takes place on a bearing surface 5.
    [0099] Subsequently, fixing 11 of the main sheet metal 2 is carried out on main drawing means 1.
    [0101] Thereafter, stretching 12 of the main sheet 2 occurs, preferably with the main stretching means 1 and therefore in the longitudinal direction of the sheet 2.
    [0103] Subsequently, a positioning 13 of at least one reinforcing piece 4 is carried out as a crossbar on the main sheet metal 2.
    [0105] Thereafter, a weld 14 of each reinforcing piece 4 is made on the main sheet metal 2.
    [0107] After the completion of the weld 14, a release 15 of the main sheet metal 2 of the main stretching means 1 is carried out, and then a removal 16 of the body or body sub-assembly resulting from the welding of the main sheet metal 2 and the parts 4 reinforcement.
    [0108] In another preferred embodiment of the method of manufacturing sub-assemblies of bodies or bodies of the invention, and schematically represented in FIG. 7, after fixing 11 of the main sheet metal 2 on the main drawing means 1 another fixing 17 of the main sheet 2 in additional positioning and / or stretching means 6, that is to say, sheet 2 can be fastened both on its smaller sides and on its larger sides.
    [0110] Simultaneously with actuation 12 of the main stretching means 1 by stretching the main sheet 2 in a stretching direction, another added stretching 18 of the main sheet 2 with the additional positioning and / or stretching means 6 takes place, stretching the main plate 2 in a direction orthogonal to the other direction of stretching 12 provided with the main stretching means 1.
    [0112] In this preferred embodiment schematically represented in FIG. 7, another stretching 20 of the main sheet 2 also takes place after the welding 14 of the reinforcing part 4 on the main sheet 2 and before the release 15.
    [0114] In addition to the release 15 of the main sheet 2 of the main stretching means 1, another release 19 of the main sheet 2 of the positioning and / or stretching additional means 6 may take place, and before or after one of the the other, always taking into account different parameters such as time, temperature of the sheet metal 2, manufacturing requirements, among other factors, since it may be possible that for certain specific applications, the release 15, 19 may be prolonged in time.
    [0116] As the main sheet 2 is of low thickness preferably, with the stretching effect conferred by the arrangement of the invention, a much improved finish quality is achieved, as well as a substantial decrease in deformations in the body or body subset resulting, unlike conventional welding operations.
    [0118] The details, shapes, dimensions and other accessory elements, as well as the materials used in the manufacture and execution of the system and method of manufacturing subsets of bodies or bodies of the invention, may be conveniently replaced by others that are technically equivalent and don't stray of the essential nature of the invention nor of the scope defined by the claims that are included below.
