Definitions

  • the invention relates to a container made of sheet metal, in particular a barrel, with a preferably cylindrical body, one end of which is closed off by a base connected to it and the other by a cover, the connection of the cover or the cover engaging slightly into the body of the container
  • the bottom is secured to the fuselage by a weld (see preamble of claim 1).
  • DE-C 733 200 already recommends a method in which a secure and sealed connection and a stiffening of the edges formed are to be achieved by resistance welding of the areas encompassing one another even after partial deformation.
  • containers are to be produced by connecting the bottom and the fuselage to one another by welding with little or no folds and without special sealing measures.
  • the invention is based on the object of developing the known manufacturing methods and creating a larger, stable container, preferably a barrel, which can be easily, easily, easily and with little effort, and which also allows the manufacturing process in to divide more desirable and advantageous.
  • the lid and base are advantageously punched out of sheet metal strips, but additionally provided with a cylindrical embossing of shallow depth, which can be created by non-cutting shaping, for example a pressing or deep-drawing process, although stamped blanks can be embossed, but it can be has proven the impressions in a Press in the metal strip and then punch out the blanks centrally.
  • covers and bases produced in this way can easily be inserted centrally into the end regions of the fuselage and fastened there in a sealed manner by a welding process. The depth of the insertion is already limited without machining the end faces of the hulls by the board of the lid or the bottom, which lies on these end faces.
  • the finished barrel proves to be extraordinarily stable, since the jacket of the indentation engaging in the end of the fuselage additionally reinforces the end area of the fuselage, and a further stiffening takes place through the flanged or rolled edge of the rim.
  • the connecting seam is placed so far inwards that the seam area is no longer subject to any significant deformation when gripping even stronger external forces.
  • the formation of the weld seam is supported by the fact that the inner surface of the fuselage initially lies firmly on the surface of the embossment even in the area of this weld seam during welding.
  • Fig. 1 the end of a fuselage 1 is shown broken off and cut, which is closed by a cover 2.
  • This cover contains an indentation 3 in the center, which is dimensioned such that its jacket 4 lies at least with a partial region widened by a bead 10 under prestress on the inner wall of the jacket.
  • the outer edge of the rim 6 is rolled inwards to form a flange 8.
  • a weld 11 which is effected by means of a laser which expediently attacks the fuselage 1 from the outside, but could also act on the bead and fuselage from the inside if necessary.
  • connection by means of a continuous, expediently slightly overlapped weld seam eliminates the need to use separate seals or to apply sealing compounds in the connection area.
  • the assembly of the bottom or lid and the fuselage is very simple, since these with their leading impressions are simply inserted into the openings of the fuselage 1 until their board 6 comes to rest on its end face 7.
  • Such manufacturing also allows a division of the stations required for the production of barrels, so that no large streets are required, in which the performance of the individual stations must be strictly coordinated with one another: in a first step, the fuselage cuts as well as the lid and bottom can be made punched and pressed or drawn.
  • the board 6 can initially remain stretched, as shown in broken lines in the figures; however, there is also the possibility of producing the respective flanging during the manufacture of the lid and base. Either it only takes place, as shown, for example, in FIG. 1, by 270 ° while maintaining a short distance to the outer jacket of the fuselage 1, the curling can also, as shown in Fig. 2, take place at a larger angle, for example. 360 °, and the rolled-up legs can be so close to the jacket 4 that the outer jacket when pressed onto the fuselage formed flaring 8 is pushed back elastically.
  • lids with a flat shelf are used to build up barrels, their shelves must be rolled in after the connection to the fuselage, for example to avoid the possibility of injury, but also for further stabilization; the use of a lid already flanged saves the subsequent rolling process.
  • the production can be divided on the basis of the spatial shape found so that in the first stations the lid and base are formed and initially only a cut of the fuselage is made, while in further stations the cut of the fuselage is rolled and welded along a generatrix formed, and then the lid and bottom are inserted and also welded. In this case, the curling of the shelf would be added to the production of lids with a stretched shelf.
  • covers and body blanks can be produced, if necessary, from which one or more production lines which produce the finishing work;
  • the prefabricated blanks, lids and bottoms centrally and setting up the finishing lines in a decentralized manner so that the necessary transport routes do not have to be burdened with the large-volume, finished drums, but rather can be used to a greater extent with their parts, which are packed much more densely.
  • the production lines required here are of such small dimensions that, if necessary, they can be relocated or even designed to be mobile and, for example, can be accommodated in and or transported with one or more containers.
  • a slightly protruding bead 10 was provided for producing an intimate mechanical contact in the area of the weld seam 11, which is followed by an area 9 of somewhat reduced diameter in the direction of the board, which is illustrated in the figure by an exaggerated gap.
  • the fixed support of the walls to be connected by the weld seam 11, which is provided to facilitate and simplify welding, can also be achieved according to FIG. 3 by an annular recess 16 provided at the level of the weld seam 11 to be introduced; the other designations are taken from the previous figures.
  • annular recess 16 provided at the level of the weld seam 11 to be introduced; the other designations are taken from the previous figures.
  • the possibility of an annular depression 16 pressed into the fuselage 1 can be supplemented or replaced by the further possibility of providing tensioning elements which encompass the end of the fuselage and pretension it against the jacket, or else to provide tensioning means in the jacket which push radially outwards.
  • Such prestressing means can only be effective in the area of elastic deformation, but this area is preferably exceeded, if necessary slightly, so that additional permanent deformations remain.
  • FIG. 4 A similar variant is illustrated with FIG. 4 and explained with the known reference symbols, which in addition to the accumulation of rain and spray water-delimiting holes has a cantilevered edge 15 which reduces the tensile and shear forces which stress the weld seam 11.
  • a quasi trapezoidal bead 19 used, which can also be produced with larger radii of curvature.
  • holes 13 and 14 ensure that water accumulation is limited, while in the area of the weld 11 the desired surface pressure which favors welding, while at the same time incorporating a certain locking effect, is achieved by means of a bead 10 which is secured in a bead 20 in the bead 20 Fuselage engages, the depth of which is less than the height of the bead 10.
  • the invention not only permits the problem-free and inexpensive production of drums, leakage problems are avoided and the stability of the container is improved, and it has been shown to be essential that complete production lines previously used with such a design can be divided up without difficulty in such a way, that instead of a central production that is to be carried out without an intermediate storage facility, the switching on of intermediate storage facilities can take the place of a division of production into a central manufacturing process for the fuselage cuts, the covers and bottoms, and a finishing train, possibly connected via long transport routes.
