Definitions

  • the invention relates to a circuit board for a structural component, a structural component and a Method for producing a structural component for motor vehicles according to the Preambles of claims 1, 5 and 11.
  • DE 43 07 563 C2 shows such a board and such a method.
  • a circuit board that a Base plate and at least one reinforcing plate, which at least the base plate partially covered and e.g. by spot welding, adhesive or welding is connected to the base plate.
  • This board then undergoes a forming process subjected to being brought into a desired shape.
  • the problem here is that the base plate and the reinforcing plate in the joint forming process are stretched or compressed differently. Doing so especially the reinforcement plate in the event of a bend in which it is on the inside smaller radius of curvature sits, more compressed and at a bend where it is on the outside sits, stretched more, while the base plate accordingly vice versa is stretched or compressed. Thus there is a general tendency to either Wrinkling when compressed or cracking when stretched. In both cases the material properties of the structural component deteriorate.
  • the strength of the structural component can usually only be achieved by using a higher material thickness can be guaranteed, since when using thin sheets Risk of crack formation is too great and also the impairment due to the formation of folds is too strong. However, this in turn increases the total weight and material costs elevated.
  • the invention is therefore based on the object of a circuit board for a structural component and a To design a method for producing a structural component for motor vehicles in this way and to further develop the fold formation and crack formation in the blank during the forming process is kept low and yet a low overall weight is maintained.
  • a deformation reserve in the reinforcing plate can result in a greater elongation of the reinforcement sheet by smoothing it without one Material thinning can be achieved.
  • the deformation reserve can in particular have a higher effective surface and e.g. through different structuring in the reinforcement plate are formed.
  • the reinforcement plate is compressed thereby also absorbed by the deformation reserve, e.g. the vault structure one locally bulges, without wrinkles being formed in the reinforcing plate become a preferred kinking of the structural component along some lines to lead.
  • a circuit board 4 has a base plate 2 on which a reinforcing plate 1 is attached. On the reinforcement plate are in predetermined areas Deformation reserves 3 formed, the higher effective due to structuring Have surface than other areas of the reinforcement plate or the base plate 2.
  • FIG. 1 shows a reinforcing plate 1 designed as a waffle plate
  • FIG. 2 shows a reinforcing plate 1 designed as a scale plate
  • 3 is a Reinforcement plate 1 shown, which is designed as a vaulted structured sheet.
  • the Waffle plate shows pyramid-like elevations and the scale plate elongated Elevations, which are separated from each other by webs; but there are also appropriate training possible, in which the respective surveys without such Adjacent webs directly and / or have additional depressions.
  • arched sheet metal directly limit the elevations without webs to each other.
  • the reinforcing plate 1 is preformed accordingly Deformation reserve available, which during subsequent forming, e.g. Deep drawing can be degraded without stretching the material too much. Furthermore, the required material expansion or expansion in comparison to that of one is not Preformed reinforcement plate 1 relatively lower, so that wrinkling of the reinforcement plate 1 during the joint forming process with the base plate can be reduced. This has the advantage that there is no significant reduction in the Material thickness is done.
  • the reinforcement plate 1 shown in FIGS. 1 to 3 is now according to FIG. 4 before joint forming with the base plate at least partially with the base plate connected. This can be done, for example, using an appropriate spot welding technique, Laser welding technology or adhesive technology, possibly combinations of these techniques respectively. It is advantageous if in the area between the base plate and the Reinforcement plate 1 appropriate corrosion protection measures are carried out. In Depends on where the structural component generated is used on a motor vehicle the structural component can also be a relatively large base plate and arranged thereon have a plurality of reinforcement plates 1.
  • the areas with ridges and depressions are smoothed without a larger material flow must take place or a larger material thinning in the Area takes place. Furthermore, the ridges and valleys in a compression compressed or enlarged without forming larger crease lines that lead to a Weaken the material.
  • the reinforcement plate 1 shown in FIGS. 1 to 3 can be used in different areas also a different, but then certain material thickness in the respective areas have so that when forming the reinforcing plate 1 to produce the Structural component in these areas then an optimal material flow or an optimal Material expansion can take place. This can be caused by certain steels or materials are supported, especially if the base plate and the reinforcement plate 1 each have a certain structure.
