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, 6 and 9.
  • DE 43 07 563 C2 shows such a board and such a method.
  • a circuit board 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 Structural component and a method for producing a structural component for motor vehicles develop in such a way that the formation of folds and cracks in the board when Forming process can be kept low and still a low total weight is observed.
  • FIG. 1 and 2 show a reinforcing plate 1a, which has a plurality of through holes 2a has and is designed as a perforated plate.
  • the through holes 2a are circular here educated.
  • Fig. 2 shows a reinforcing plate 1a, which has a plurality of through holes 2a are cruciform.
  • the through holes 2 can also have other geometric shapes, for example, slit-shaped or elongated.
  • each corresponding to the geometric arrangement of the through holes run parallel and at an angle ⁇ or ⁇ , where ⁇ is shown in FIG. 1 of the symmetrical arrangement 60 degrees and ⁇ in the arrangement shown in FIG. 2 90 degrees is.
  • the reinforcement plate 1 shown in FIGS. 1 and 2 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.
  • the reinforcement plate 1a, b shown in FIGS. 1 and 2 is now with the base plate 4th at least partially connected. This can be done, for example, by a corresponding Spot welding technology, but also through a special joining technique or adhesive technique or Combinations of these procedures are used. It is advantageous if in the area between Base plate and the reinforcement plate 1 corresponding corrosion protection measures be performed. Depending on where the structural component created on a If the motor vehicle is used, the structural component can also have a relatively large base plate and arranged thereon have a plurality of reinforcement plates 1.
  • the circuit board formed from base plate 4 and reinforcing plate 1 is one Forming process, e.g. subjected to a deep-drawing process.
  • the two sheets reshaped together.
  • the holes 2a, b in the reinforcement plate deformed according to the local deformations, e.g. enlarged or reduced or changed asymmetrically.
  • the loads on the reinforcement plate by a Deformation of the holes are recorded so that a material flow over a larger one Surface and crack formation is avoided even with thin reinforcement plates.
  • the web-like areas 3a, b between the through holes in the Reinforcement plate can be stretched more than the material of the base plate. So can an asymmetrical deformation of the board is absorbed by the reinforcement plate by deforming the holes and the web-like areas -ggf in different directions to different degrees - be stretched.
  • This material expansion or expansion depends, among other things, on the geometry of the through holes 2 and the width or length of the between the through holes 2 remaining webs 3.
