Definitions

  • the invention relates to a sheet metal element, in particular as a semi-finished product, as can be used for example for the production of rail vehicles, as well as to a method for constructing a surface element thereof.
  • Such a sheet metal element is used for example in the DE 10 2004 019 448 A1 described. It is made exclusively by rolling and shows along the rolling direction a variable sheet thickness for its first part, while a second part of the sheet metal element consists of rolled sheet with a constant sheet thickness.
  • Such a sheet metal element offers the advantage that differentiated strengths can be realized within the sheet metal element.
  • this sheet metal element does not allow due to the limited manufacturing widths, but to realize a large format that allows, for example, the structure of the outer panel of a rail vehicle side wall of a few sheet metal elements.
  • the technical background of the invention also includes sheet metal elements which are individually cut from flat products and welded to a surface element, such as a side wall of a rail vehicle.
  • a surface element such as a side wall of a rail vehicle.
  • Such surface elements are made of commercially available flat products, such as strip material or sheet material, the same material thickness and material quality.
  • the laser cutting method is preferably used as a separation method for more accurate production with higher edge quality and process speed.
  • individual areas of the surface element can be locally reinforced or designed to be weaker targeted in terms of lightweight in the areas of lower loads.
  • individual sheets are cut with the same and / or different material thickness or quality, from the flat products and welded together to form the surface element.
  • local reinforcing sheets can be used, also known as patchwork technology.
  • the window blank is widened at least by a cutout that matches the contour of the respective reinforcing plate, and the reinforcing plate is inserted there appropriately by means of a suitable welding method.
  • the reinforcing plates are placed only on the surrounding surface element and firmly connected to this by means of a suitable welding process.
  • reinforcing plates can be used for reinforcing edge regions of the surface element, which represent, for example, the force introduction region of the side wall to the adjacent subframe of the rail vehicle, whereby the dimensions of the reinforcing region are taken into account accordingly in the production of the blanks of the adjacent metal plate.
  • the reinforcing plates themselves are also tailored to the contour of the adjacent sheet metal field and then welded.
  • the present invention seeks to provide a sheet metal element, in particular as a semi-finished product, which is due to a low workload for the formation of surface elements, such as side walls, etc.
  • a method for producing a surface element is to be specified.
  • a sheet metal element in particular as a semi-finished product, which has an elongated shape and in its transverse direction has at least two sheet metal element segments with different material thickness and / or quality.
  • Such a sheet metal element can readily be made, depending on the manufacturing process, one or more sheet metal coils. An automated production also of sub-elements thereof is possible.
  • the at least two sheet-metal element segments have a different material thickness and are produced by variable rolling.
  • a single sheet metal coil is divided by variable rolling transversely to the rolling direction in two mutually parallel sheet metal element segments.
  • the at least two sheet metal element segments each consist of cut strips of material, the mutually facing edges are joined together.
  • Such tailored strips of material are also referred to in the art as “tailored strips”.
  • Their associated manufacturing process goes from the EP 0 299 358 A1 out.
  • tailored blanks can be produced, namely as prefabricated strip material, wherein at least two sheets are welded together as strip material with different material thickness and / or material quality in a continuous process by means of a laser beam, wherein the weld seams run parallel to one another , This creates a new band, which in turn can be wound into a coil.
  • the new strip material can then be cut to "tailored blanks" by means of separation processes.
  • the surface elements produced by means of flexible rolls can also be referred to as "tailored blanks".
  • the flexible rolling processes required for this purpose are for example in the DE 100 41 280 C2 , of the DE 101 56 087 B4 and EP 0 788 849 A1 described.
  • the joining can preferably be carried out with the aid of a welding operation, in particular a laser welding process.
  • the sheet metal element has three sheet metal element segments. By further cutting such a sheet metal element results, as will be explained in more detail later, a wide range of applications of cut from the sheet metal element sub-elements.
  • the outer two sheet metal element segments are preferably of the same material thickness and quality, wherein the middle sheet metal element segment deviates in terms of its material thickness and / or quality from the two outer sheet metal element segments.
  • a sheet metal element has the advantage that by cutting the sheet metal element in its longitudinal direction two sub-elements arise, each having a sheet metal element segment, which is characterized by a higher mechanical strength.
  • Such a sheet metal element is particularly suitable for stiffening openings in, for example, a side wall of a rail vehicle.
  • middle sheet metal element segment is mechanically higher loadable than the two outer sheet metal element segments, there is the advantage that with the same transverse dimensions the individual sheet metal element segments a cutting of the sheet metal element in its longitudinal direction produces two sub-elements, which are versatile in rail vehicle construction can be used.
  • a sheet metal element BE1 which is passed in a rolling direction A between the rollers W1, W2.
  • the rollers W2 have different distances to the opposite, large roller W1, resulting in a profiling of the sheet element BE1.
  • the sheet metal element BE1 with different material thicknesses is present transversely to the rolling direction.
  • the sheet metal element BE1 at its longitudinal edges of higher material thickness than in its central region.
  • FIG. 2 now shows a cross-sectional view of a principle after the in FIG. 1 illustrated rolling process produced sheet metal element BE2, in which a central sheet segment has a greater material thickness than outer sheet segments BR1, BR2.
  • the sheet metal element BE2 is in perspective also in FIG. 3 to see. It has an elongated, flat shape in which a length-to-width ratio is greater than 2: 1, preferably greater than 3: 1.
  • the right part of the perspective view of FIG. 3 shows sub-elements U1, ..., U3, all of which can be produced from the sheet metal element BE2 by laser cutting.
  • the sub-elements U2, U3 result by a central longitudinal section of the sheet metal element BE2, which is symmetrical with respect to its central axis.
  • the resulting sub-elements U2, U3 each have two segments, one of which has a smaller and the other has a greater material thickness.
  • the subelements U1, of which in FIG. 3 four pieces are shown, all can be produced by cutting the sheet metal element BE2 in its transverse direction.
  • FIG. 4 now results in a perspective view of a surface element, which consists of the sub-elements U1, U2, U3 of FIG. 3 is manufactured and can serve for example to build the side wall of a rail vehicle.
  • the four sub-elements U1 are arranged side by side in such a way that the segments of greater material thickness are parallel to one another.
  • the two sub-elements U2, U3 each form the upper and the lower edge of the surface element FE1.
  • FIG. 5 now shows the surface element FE1 of FIG. 4 with additional openings 01, 02, which can serve for example for receiving windows. It turns out that the segments of the sub-elements U1 with larger material thickness window frame portions of the openings 01, 02 form.
  • FIG. 6 shows a sheet metal element BE3, which is also made with the aid of strip profile rolls, but only two sheet segments BR3, BR4 has.
  • the material thickness of the sheet segment BR4 is greater than that of the sheet segment BR3.
  • FIG. 7 shows the sheet metal element BE3 and subelements U4 produced therefrom.
  • the subelements U4 are produced by cutting the sheet metal element BE3 in its transverse direction.
  • the sheet metal element BE3 may already be dimensioned such that the side wall of a rail vehicle or other surface elements can be produced in combination with similar sheet metal elements.
  • FIG. 8 now shows a surface element FE2, made of the sub-elements U4, wherein the respective sheet metal segments BR4 of the parallel arranged sub-elements U4 are directed to the outside.
  • the width of the sheet metal element BR4 is dimensioned smaller with a larger material thickness than that of the sheet metal segment BR3.
  • FIG. 9 shows the surface element FE3 with additional openings 03, 04 for receiving windows. Again, there are window frame sections due to the sheet segments BR4, which extend along the upper and lower edges of the openings 03, 04.
  • FIGS. 10 to 17 correspond essentially to those of FIGS. 2 to 9 , so that the same reference numerals are used for functionally identical elements. It should be noted, however, that the representations of the FIGS. 2 to 9 refer to rolled sheet metal elements, while the representations of FIGS. 10 to 14 Sheet metal elements of so-called.
  • Tailored strip strip material have the object, ie the starting material already has various sheet metal segments BZ, BR1, BR2, BR3, BR4, which can be produced for example by laser welding in the longitudinal direction of sheet metal elements BE4, BE5.
  • the representations of the FIGS. 10 to 17 completely with those of FIGS. 2 to 9 so that reference can be made to their description.
