Definitions

  • the invention relates to a method for producing a container from sheets of aluminum or an aluminum alloy, wherein the surfaces of the aluminum sheets are at least partially visible on the finished container. Moreover, the invention relates to a corresponding container at least partially consisting of sheets of aluminum or an aluminum alloy.
  • a container in the context of the present invention are understood in particular technical container for the transport of liquid, gaseous or solid materials, such as pressure vessels, fuel tanks or transport containers for liquid or pourable grades.
  • Such a container and a corresponding method for its production are already out JP-2000 234699 A known.
  • these containers consist of a plurality of assembled or also of individual, shaped aluminum sheets.
  • Aluminum sheet trays are increasingly replacing containers made of sheet steel due to weight savings.
  • mechanical properties of the containers made of aluminum sheets are also decorative properties of the container in the foreground.
  • fuel tanks for trucks often consist of several joined segments, which are made of individual aluminum sheets. Due to different production parameters or a different storage time of the aluminum sheets used, these often have different surface appearance.
  • the fuel tanks are therefore surface-coated or painted in order to obtain a homogeneous surface.
  • the problem with the surface coating of the container is that it is complicated and leads to additional costs in the production of the container.
  • the surface-coated containers do not exhibit the typical decorative metallic luster of an uncoated aluminum surface. Nevertheless, in order to provide containers with uncoated aluminum surfaces and a uniform appearance, prior to assembly, the various aluminum sheets have been subjected to scrutiny with respect to their surface appearance, and only aluminum sheets having the same or similar characteristics have been used for the production.
  • the present invention has the object to provide a method for producing a container made of aluminum sheets, with which containers with decorative, visible aluminum surfaces can be produced with little effort.
  • the invention has for its object to propose containers produced by the method.
  • the above-described object is achieved for a generic method according to claim 1, characterized in that by forming and / or joining the aluminum sheets, which are visible on the finished container, the container is at least partially prefabricated and subsequently the entire, at least prefabricated containers are subjected to surface treatment by mechanical blasting, leaving the visible surfaces of the aluminum sheets unattended.
  • the different appearance of the aluminum sheets used can be changed so that the containers have aluminum surfaces with a uniform, decorative appearance and metallic luster.
  • resulting surface defects which have so far led to rejects in the production, eliminated to some extent, so that the rejects and rework share in the production of the container with the inventive method can be significantly reduced.
  • the containers thus produced can be used very well uncoated.
  • a further coating of the aluminum surfaces can be dispensed with, so that the method according to the invention is particularly cost-effective.
  • the aluminum surfaces of the containers are solidified by mechanical blasting, making the containers more resistant to mechanical surface damage.
  • the container is finished by forming and / or joining the aluminum sheets and the entire finished container is mechanically blasted, so that the surface treatment of the container takes place in the last manufacturing step. Due to the advantageous method, surface-defect-free containers can therefore be made available which have a particularly decorative surface. Preferably, at least the mechanically blasted aluminum surfaces are not subjected to any further coating and therefore remain uncoated.
  • the mechanical blasting is carried out by glass beads, corundum, fine corundum, sand and / or steel balls.
  • Glass beads, corundum, corundum and sand have the advantage over steel balls that they do not lead to any additional entry of iron in the blasted aluminum surfaces, which should be avoided for corrosion reasons.
  • steel balls high solidification of the aluminum surface can be achieved, so that the resistance of the aluminum surfaces to mechanical influences, such as rockfall, can be increased more.
  • other agents or their mixtures for mechanical blasting are also known as rockfall.
  • the container is a pressure vessel, a fuel tank, in particular a modular fuel tank or a transport container for liquid or bulk goods. All of these containers are often in a modular design or from a plurality of Aluminum sheets produced and preferably used uncoated, so that these containers can be produced particularly economically with the inventive method.
  • the aluminum sheets consist of an aluminum alloy of the type 3xxx, 5xxx and / or 6xxx.
  • Aluminum alloys of the type 3xxx are characterized by a good forming behavior, so that the joining and forming of the aluminum sheets to a container succeeds in a simple manner.
  • the strength values of the 3xxx aluminum alloys are not as high as those of the 5xxx and 6xxx type aluminum alloys.
  • Aluminum alloys of type 6xxx have the highest strength values of the mentioned types of alloys.
  • the forming properties of the 6xxx aluminum alloy are again not as good as those of the 5xxx type.
  • a good compromise between very good strength properties, good formability and good corrosion resistance is the aluminum alloy type 5xxx. All three types of alloy mentioned have in common that they tend in a mechanical blasting to a high surface hardening, the resistance of the aluminum surface in terms of mechanical damage clearly improved.
  • the above-described object is achieved by a generic container according to claim 5, characterized in that the visible aluminum surfaces after assembly of at least the visible aluminum sheets by joining and / or forming are surface-treated by mechanical blasting of the entire, at least prefabricated container, the visible surfaces of the aluminum sheets being unvisited.
  • the mechanical blasting of the aluminum surfaces after assembly of the container results in a homogeneous appearance of the aluminum surfaces, even if they have surface defects or different surface appearance from surface treatment by mechanical blasting from the forming process.
  • the visible surfaces of the aluminum sheets of the container are uncoated, so that the costs for the surface coating, for example for painting and drying, can be saved.
  • the aluminum sheets of the container are made of an aluminum alloy of the type 3xxx, 5xxx and / or 6xxx.
  • the aluminum alloys mentioned can be blasted well mechanically and show a clear hardening of the surface after blasting.
  • the different types of aluminum alloys depending on the properties described above for the production of a container according to the invention or individual segments of a container according to the invention can be selected.
  • the container according to the invention is a pressure vessel, a fuel tank, in particular a modular fuel tank or a Transport container for gaseous, liquid or pourable goods.
  • the said containers are usually made of a plurality of aluminum sheets, so that their surfaces must be coated in order to obtain a uniform appearance of the surfaces.
  • the mechanical surface of the various surfaces is given a uniform surface texture by the mechanical blasting performed after the assembly, thereby even eliminating surface defects of production at least to a certain extent.
  • the preferably uncoated used pressure vessel, fuel tank and transport container can be provided according to the invention in a simple and cost-effective manner and yet meet high decorative requirements.
  • the container is constructed of several segments made of aluminum sheets.
  • the individual segments then do not have to be selected according to the invention according to their surface properties and joined together, so that the amount of rejects in the production of the container can be significantly reduced.
  • the Indian Fig. 1 shown fuel tank 1 of a truck consists of three segments 2, 3, 4, which are interconnected by welds 5, 6.
  • the three segments 2, 3, 4, separated from each other, produces aluminum sheets originating from different production lots.
  • the different segments 2, 3, 4 can also consist of different, adapted to the respective function aluminum alloys or have only different thicknesses.
  • the different functions of the segments are indicated by a filling opening 3a and treads 4a.
  • the associated different process parameters of the aluminum sheets used for the production of the segments 2, 3, 4 results in a different appearance of the aluminum surfaces, which is perceived particularly clearly by the human eye.
  • the mechanical blasting of the aluminum surfaces of the container according to the invention results in that scratches or defects introduced to the surfaces, for example, in the manufacture of the sheets, can be eliminated to some extent.
  • the reject and reworking share in the production of the containers can therefore be significantly reduced.
  • a particularly good solidification of the surface without removing too much material on the aluminum surface is further achieved by the particles, which are used for blasting, are directed substantially perpendicular to the radiating aluminum surfaces. It is also conceivable to direct the particles at a different angle to the aluminum surface.
