Definitions

  • the invention relates to a method for flexible rolling of metal strip or metal blanks, wherein the metal strip or plates in the longitudinal direction of Rolling over the entire length from one initial thickness to a variable one Final thickness is rolled, as well as products produced by this process.
  • a method of this kind is known from DE 197 04 300 A1. This is the starting material initially to a temperature above the crystallization temperature heated and then rolled out. This is what happens after the Hot rolling to a recrystallization of the material structure. From the wording a recrystallization temperature of above 700 ° is clear that as the starting material alloyed steels are to be assumed.
  • the rolled strip can be made of steel or non-ferrous metals consist.
  • From DE 199 26 228 A1 discloses a method for rolling aluminum sheet or Band known, in which this transverse to the conveying direction and additionally in the longitudinal direction each receives a non-uniform thickness profile. This requires a rolling stand with at least one work roll with different diameter ranges across to the conveying direction of the aluminum sheet or strip.
  • the present invention is based on the object, the field of application of to expand the method mentioned above and in particular the method specially adapted selected light metal materials.
  • the solution to this consists in a method in which as tape or board material Light metals, including their alloys, in particular aluminum or Magnesium are used and which is characterized in that the final thickness of the tape or board material comprises at least three different thickness stages. There are transition areas between individual thicknesses of constant thickness with variable thickness, in particular with a gradient between 1:40 and 1: 4000, defined as the thickness difference over length.
  • the process products according to the invention can, for example, weight and strength optimization be further advanced in vehicle construction. While, for example, the largest Thickness level can be used to represent connection connections are Targeted adjustments to different load profiles with several additional thickness grades possible. This includes both the load in the elastic deformation range as well as loads in the event of a crash with plastic deformation.
  • the thickness of the material over the entire length is reduced by at least 5%, based on the with 100% assumed initial thickness. This creates a preliminary or intermediate product improved quality and increased dimensional accuracy.
  • the final thickness differences of the material between thickness levels adjacent to the thickness At least 10% should preferably be more than 20% in order to be targeted usable strength differences of the precursor for it to be produced To produce sheet metal parts.
  • Preferred thickness ranges for the at least three thickness stages are in subclaims named.
  • the selection of concrete values depends primarily on the strength requirements to be produced from the material according to the invention Finished product.
  • the change between the different thickness stages can be at the board or Band material in any order, with this order on Repeat strip material periodically.
  • the extent of the maximum thickness reduction should be 70%, based on the initial thickness of 100%, do not exceed.
  • the minimum gradient proposed is 1: 4000. In practice will be Values near the maximum gradient outweigh.
  • the material cold rolled or for hot rolling to a temperature between 350 and 470 ° C are heated.
  • the material for hot rolling to a temperature between 180 and 280 ° C are heated.
  • the invention further includes metal strip produced by said method or manufactured metal plates and surface elements produced therefrom, Pipes or profiles.
  • the flexibly rolled material can be cut to length or cut to different sizes Be further processed and different uses be supplied.
  • a board or a belt section 1 is shown prior to rolling, wherein its thickness is referred to as initial thickness with h0. From this initial thickness h0, the material is rolled in a single pass through flexible rolling to three different thickness stages h1, h2, h3 with h0>h1>h2> h3.
  • h1 h0 - .DELTA.h 1
  • h2 h 0 - .DELTA.h 2
  • h3 h 0 - .DELTA.h third
  • h1 ⁇ h0.
  • h2 ⁇ h1 and h3 ⁇ h2.
  • the rolling direction can in this case run from section 3 to section 4 or vice versa.
  • a third transition section not shown, it is possible to change over from the thickness h3 to the thickness h1.
