Definitions
- the invention relates to a method for producing a double-layer sheet for a Motor vehicle for receiving an acting load according to the preamble of Claim 1.
- the double-layer sheet has a first upper and a second lower plate, which are connected to each other, to realize a spacing of this plate corresponding knobs are provided between the first and the second plate, wherein the knobs are formed on at least one of the plates.
- DE 195 03 166 A1 shows a double-layer sheet and a method for the production a double-layer sheet used as a double-layer sheet in a motor vehicle can be.
- the lower plate that is, the lower plate with pronounced Provide knobs.
- This arrangement can also be in do the reverse (top plate nubbed, bottom smooth).
- the invention is therefore based on the object of a method for producing a To design and further develop double-layer sheets for a motor vehicle, that a double-layer sheet is created, the rigidity or strength of which is increased, without being associated with a significant weight gain.
- the stiffness and Strength of the double-layer sheet formed from the first and second plate is increased.
- the knobs with the stiffening beads are now heavier, so only compressible by greater forces. This is particularly the case with deep-drawing of beads according to the invention in a first and second plate formed support plate (double-layer sheet) is advantageous, the geometry of the beads, the geometry of the stiffening beads and the material thickness of the panels be matched or selected that a predetermined plate distance in front and is guaranteed after the deep-drawing process of the double-layer sheet.
- the above-mentioned disadvantageous effect of the compression of the double-layer sheet is therefore largely avoided and better spacing of the first and the second plate to each other - now also after said deep drawing - guaranteed.
- FIG. 1 to 3 show a double-layer sheet or a support plate 1 for a motor vehicle for receiving a load acting on the double-layer sheet 1.
- Support plate 1 is composed of a first, upper plate 3 and a second, lower plate 4 educated.
- Surface of the double-layer sheet 1 formed bead 2 may be provided, which in the Double-layer sheet 1 is formed without the distance d between the plates is reduced in this area.
- the knobs 5 ensure the spacing of the first and second plates 3, 4 especially in a deep drawing process.
- An advantageous one Stud spacing a is between 7.5 and 15 mm, with a sheet thickness of 0.2 to 0.6 mm of the smooth plate and 0.2 to 0.5 of the knobbed plate and one Plate spacing d from 0.8 to 2 mm.
- FIG. 2 shows a double-layer sheet 1 with a first plate 3 and a second plate 4, a knob 5 being formed in the second plate 4.
- a knob 5 being formed in the second plate 4.
- the stiffening beads 7 are wave-shaped educated. So perpendicular to the surface of the double-layer sheet 1 becomes a higher one Stiffness achieved.
- the stiffening beads 7 are now designed so that the compression or bulge Stiffening beads 7 a higher force is required than for compression or buckling the beads 2. This is particularly due to the wavy structure of the knobs 5 reached.
- the geometry of the beads 2 and the geometry of the stiffening beads 7 as well as the material thickness of the first and second plate 3, 4 can now according to the invention be coordinated with each other that a certain distance d between the first and second plate 3 and 4 is guaranteed.
- Such a design of a support plate 1 according to the method makes it possible to to produce such a support plate 1 inexpensively, so that the previously in the Additional reinforcements usual in the technology such as Deposits between the plates 3, 4 can be omitted. Consequently, there is no need for reinforcing sheet metal parts or the like be attached to such a support plate 1.
- the double-shell structure ensures a certain bending stiffness, whereby the first and second plates 3, 4 are firmly connected. Especially in this In this case, the double-layer sheet 1 has good properties for noise reduction.
- this trained support plate 1 is a utilized one Lightweight potential, with positive acoustic effects compared to the conventional Construction are given.
- a support plate 1 designed in this way is also suitable for Components with a lower proportion of deep-drawing and larger flat surfaces, because with one such a shape, the rigidity of the double-layer sheet 1 comes into its own.
- the beads 2 compressed in a known manner. Since the stiffening beads 7 are stiffer than the larger beads 2, they are compressed and only with a higher force possibly dented.
- the support plate 1 shown here can be used in motor vehicle construction in different ways be used. Uses as floor and Backrest wall element, as a reinforcement plate or as a bulkhead plate.
