Definitions

  • the invention relates to a method for producing pipes with sections of different wall thicknesses from an initially flat sheet metal.
  • a method for forming frame parts for motor vehicles belongs to the prior art, in which a metal sheet is first rolled in such a way that parallel recesses are formed. These different wall thicknesses should result from the fact that the roller has sections of different sizes.
  • the invention has for its object to provide an economical method for the production of material and weight-saving pipes, in particular as an intermediate product for components that can be exposed to different loads over their length.
  • the object is achieved according to the invention by a method in which a targeted rolling deformation of the starting sheet is carried out with sheet thicknesses which change in regions in the rolling direction.
  • the rolled sheet is then cut as required.
  • the resulting intermediate product is then formed into a tube and joined by joining technology along the abutting edges.
  • a tube can be produced which has sections of different wall thicknesses in the longitudinal axis direction.
  • This area-reduced tube thickness is used for the production of components that are under external loads, but in which the stresses that occur due to the component design are distributed over the component at different heights. Examples of such differently loaded components are body parts or chassis components of motor vehicles. If the components were dimensioned according to the maximum load, this has not only resulted in the unnecessary use of materials, but also in the past all at an unnecessary weight. According to the invention, these disadvantages are avoided in that the tubes which are used to produce the components are dimensioned differently in accordance with the subsequent load in the individual areas of the components. In this way, you can meet the expected later loads and also save material and thus weight.
  • a metal sheet with a thickness corresponding to the greatest wall thickness of the pipe to be manufactured is expediently used as the starting material.
  • the starting material can also be provided with a corresponding oversize.
  • the starting material is advantageously drawn off from a coil and fed to further processing in the rolling process.
  • a targeted partial wall thickness reduction is then carried out by rolling to match the later use of the pipes produced.
  • the invention makes it possible to adapt the rolling direction to the respective configurations of the later tube.
  • the starting sheets can also be partially rolled twice or possibly several times in different directions.
  • the respective thickness can also be varied in stages as required. Different ironing rates and different transition areas between the thicker and thinner areas are possible.
  • the transitions from one sheet thickness range to another can be stepless or stepped.
  • Rolling can take place in a two-roll stand.
  • the symmetry with respect to the central transverse plane can be influenced within predefined limits.
  • the specifically deformed sheet has deliberately varying cross-sections in order to convey the exact wall thicknesses to various areas, which are matched to the respective loads and thus the locally differing stress peaks to which these areas are exposed in practical use.
  • the sheet is cut to size, formed into a tube around the longitudinal axis and joined by joining technology along the joints. This is usually done by welding the joints. Various methods are available for this, for example laser, shielding gas, inductive or resistance welding.
  • the rolled sheet metal can be divided into sheet metal strips running parallel to the rolling direction before further processing. In this way, several tubes of the same configuration can be produced from one large output board.
  • the sheet metal or sheet metal strips can be shaped into tubes in a rolling mill.
  • a further advantageous embodiment provides that a semi-circular profile is first embossed from the rolled metal sheets in a die and then finished in a further embossing step to form the tube.
  • a pipe can also be divided into shorter lengths.
  • the method for producing tubes for the production of motor vehicle components is particularly advantageously suitable.
  • FIG. 1 shows a section of a sheet 1, in which areas 2-5 have been ironed out by a specific rolling deformation with sheet thicknesses s 2 to s 5 that change in the rolling direction WR.
  • the areas 2-5 merge into each other almost continuously by a slope 9, 10, 11.
  • the sheet 1 has an approximately smooth surface 13 on the underside 12.
  • Figure 2 shows a sheet 1 in plan view.
  • the areas 2-5 specifically have those wall thicknesses which are matched to the respective loads and stress peaks to which a pipe made from the sheet 1 is subject or which result from its practical use as a structural component.
  • FIG. 3 shows a sheet 14 which has an asymmetrical geometry, based on its central transverse plane MQ, with areas 15-18 of different sheet thicknesses s 15 -s 16 . Both the top 19 and the bottom 20 of the sheet 14 accordingly vary in different ironing rates in stages.
  • the sheet metal 14 is expediently formed into a tube such that the top side 19 forms the inside of the tube and the bottom side 20 forms the outside of the tube.
  • the board 21 is inserted into a die 22 (FIG. 4, top) and loaded by a stamp 23, as indicated by the arrow F.
  • the board 21 is forced into the die form 24 and a semicircular profile 25 is embossed (FIG. 4, middle).
  • the forming into a tube 26 in the die form 24 takes place with the aid of the plunger 27, which has a configuration with a counter-shape 28 which is matched to the tube 26 (FIG. 4, bottom).
  • the abutting edges 29, 30 are joined by means of automatic laser welding with seam detection and tracking.
  • the tube 26 thus finished is then available for further processing. It has sections with different wall thicknesses in the axial direction. This configuration is precisely matched to the later use of the tube and the loads and tensions that occur, to which the tube 26 is then subject.
