Definitions

  • the invention relates to tailored tubular blanks according to the preamble of
  • Claim 1 a set of several such tailored tubular blanks according to claim 6 and a method for their production according to claim 7.
  • Tailored tubular blanks are welded bodies that are open at the ends, either in the form of a simple tube, but also with a non-round cross-section or a cross-section that changes over the length, which can lead to a cylindrical or conical or irregular shape over the length.
  • the shape depends on the intended use and is designed for this. For the sake of simplicity, these irregularly shaped bodies are referred to below as "pipes".
  • Tailored tubular blanks are characterized by the fact that they are made from two or more sheets of different thickness and / or material quality and / or coating. The construction of such tailored tubular blanks from sheet metal with different properties results in tubes that are specially adapted in sections to the respective requirements.
  • Tailored tubular blanks of this type can be used as such or - in the main use case - can be further processed by shaping, in particular hydraulic shaping (hydroforming) to give hollow bodies of complex shape.
  • Such hollow or shaped bodies are used, for example, in automobile construction, e.g. as load-bearing components in the body (pillars, roof rails, threshold profiles, etc.) and in the substructure (chassis parts, chassis beams, cross members, muffler and catalyst housings, etc.). Areas of application other than automobile construction are also possible, especially where spatially complicated framework parts are to be used.
  • tailored tubular blanks are generally used in the technical language and therefore also in this application; in analogy to the well-known level “tailored blanks", which are also called “load-adapted blanks” in German, the “tailored tubular blanks” can also be used by "load-adapted pipes” are spoken.
  • FIGS. 1 a - 1 c show a first variant with parallel longitudinal seams, FIG. 1 a showing the flat tailored blank 1 made of sheets 1 and 2 with the weld seam 3.
  • Figure 1b shows the welded tube (tailored tubular blank) from above with the longitudinal pipe weld 4 and Figure 1c shows a cross section through the tube.
  • FIGS. 2a-2c show the corresponding tailored tubular blank (blank) with the sheets 1 and 2 and the weld seam 3, which forms the circumferential weld seam 3 after forming into a tube in the tube shown in Figure 2b (tailored tubular blanks), which forms with the Pipe longitudinal weld 4 crosses.
  • FIG. 2 c shows a cross section through such a tailored tubular blank in the area of the sheet 2. Tailored tubular blanks with transverse division, as shown in FIGS concentrate and the heat affected zones (edge areas of the actual welding zone) overlap the two seams.
  • the invention is therefore based on the object of creating tailored tubular blanks with circumferential seam and longitudinal seam, in which the disadvantages mentioned do not occur or at least to a greatly reduced extent.
  • peripheral seam or the peripheral seams if several are provided, do not intersect with the longitudinal seam or the longitudinal seams if several are provided, the above-mentioned disadvantages are largely eliminated.
  • Non-crossing seams only meet, so that one can speak of T-joints, although the seams do not usually meet at right angles.
  • Such T-joints have a low concentration of welding stresses in the area of the seam joints than is the case with crossed seams, which results in better formability.
  • the risk of welding errors when welding butt joints is less than when welding crossed seams.
  • the butt joints of the seams can also be better targeted at places that are weakly loaded technically.
  • the invention is further based on the object of providing a method for providing tailored tubular blanks which do not have the disadvantages mentioned.
  • Figures 1a - 1c a blank (tailored blank), a tailored tubular blank in plan view and a cross section through the same according to the prior art;
  • Figures 2a - 2c also a pre-board, a tailored tubular blank and a cross section according to the prior art;
  • FIGS. 3a-3c a first exemplary embodiment of the invention, likewise with a blank, tailored tubular blank and cross section;
  • FIGS 4a-4c another embodiment in which pipe sections are connected at their ends
  • Figures 5a and 5b another embodiment with pre-board and Tailored tubular blank in top view
  • FIGS. 6a and 6b show a further exemplary embodiment with a blank and tailored tubular blank
  • FIG. 7 shows an embodiment of a pre-board
  • FIG. 8 shows a further exemplary embodiment of a pre-circuit board.
  • FIGS. 1a-1b show an already explained example of tailored tubular blanks according to the prior art, the embodiment of which does not form the subject of the present invention.
  • FIGS. 2a-2c show an exemplary embodiment of tailored tubular blanks with longitudinal seam and circumferential seam according to the prior art, the improvement of which is the subject of the present invention.
  • FIG. 3a shows a first exemplary embodiment of tailored tubular blanks according to the invention, FIG. 3a showing the tailored blank or the blank 10 from which the tube frame is formed by any known tube bending method, which is then welded to the tube.
  • the pre-circuit board 10 is formed by welding two sheets 11 and 12 which are connected to one another by means of an obliquely running weld seam 13.
  • the sheets 11 and 12 can be any known sheets of different thickness and / or with different sheet properties, as is known in principle in the formation of tailored tubular blanks. If the pre-circuit board is shaped into a tube, in which the edges 16 and 17 of the circuit board are deformed away from the viewer from the plane of the drawing, a tube frame is created according to the top view of FIG.
  • FIGS. 4a-4c show a further embodiment of tailored tubular blanks according to the invention, a tube 30 being shown as an example, which has a continuous circumferential seam 33 to which two longitudinal seams 31 and 32 do not adjoin in the butt joint, the butt joints also with 34 and 35 are designated. Here, too, the joints are spaced apart from one another by a preselected amount.
  • FIG. 4c shows the two tubes 36 and 37, which serve as starting parts with longitudinal weld seams 31 and 32 for tailored tubular blanks according to FIG. 4a.
  • the tubes 36 and 37 are in turn preferably formed from metal sheets with different thicknesses and / or different material properties.
  • FIG. 4b shows a cross section through the tailored tubular blank 30 from FIG. 4a in the area of the pipe 37.
  • the present tubes 36 and 37 become conscious in the present case for the formation of tailored tubular blanks and are connected to one another with a preselected offset d of the longitudinal weld seams in an industrial environment and with as constant an offset d as possible, so that during production Set of tailored tubular blanks is produced with the same offset. Furthermore, there are tubes 30 or tailored tubular blanks which are composed of different tube parts 36 and 37.
  • Figures 5a and 5b show a further embodiment similar to that of Figures 3a and 3b, in which, however, the pre-plate 40 is composed of three sheets 41, 42 and 43, for which purpose the weld seams 44 and 45 are provided. Corresponding butt joints 46-49 are formed in the tailored tubular blank 50 with their longitudinal weld seam 51.
  • all three sheets 41-43 can have different thicknesses and / or Have material properties or two of the sheets, for example 41 and 43, can be similar sheets and the sheet 42 can be a sheet with different properties.
  • a longitudinal member can be produced which has a high strength in the middle and a lower strength or a desired compression behavior at its ends.
  • the seams 44 and 45 can run obliquely and the other seam, as in the prior art, can run straight and thus cross the longitudinal seam if this is desired.
  • FIGS. 6a and 6b show a further exemplary embodiment, in which in turn the pre-circuit board 60 is composed of three metal sheets, in which case the one seam 65 in the corresponding tailored tubular blanks 69 forms a longitudinal weld seam and the oblique weld seam 64 forms the circumferential seam.
  • the sheets 65, 62 and 63 can in turn have different thicknesses and material properties, and the butt joints 66 and 67 which arise in the tailored tubular blanks, as in the examples already shown, have the advantages mentioned compared to a crossing course according to the prior art of the weld seams.
  • FIG. 7 shows a further pre-circuit board, in which it is readily apparent that in this case the joints 74 and 75 of the weld seam 73, which connects the sheets 71 and 72, are at right angles to the longitudinal weld seam in the tailored tubular blanks.
  • this case one can speak of a T-shaped butt, whereby this designation can also be used for the other butt joints according to the invention, even if the seams do not meet exactly at right angles.
  • FIG. 8 shows a further example of a pre-plate 80 with three welded sheets 81, 82 and 83, the joints of the weld seams 84 and 86 with the longitudinal weld seam of the tubular frame formed from this pre-plate or subsequently welded tailored tubular blanks also having a predetermined offset along the longitudinal weld seam and form a joint with the longitudinal weld without crossing.
  • a recess could also be provided, which also on the tailored Tubular blank forms a recess.

Abstract

L'invention concerne des ébauches tubulaires sur mesure (20) formées en plaçant le cordon de soudure circulaire (13) et le cordon de soudure longitudinal (18) de façon que les cordons ne se croisent pas mais forment uniquement un point de jonction (14, 15). On peut ainsi produire des ébauches tubulaires sur mesure présentant une meilleure déformabilité.
