Definitions

  • the invention relates to a method for producing a tube container according to the preamble of the main claim.
  • the invention has for its object to simplify the known manufacturing process and technologically improve the products.
  • the object is achieved by the invention with the characterizing features of the main claim.
  • the measures according to the subclaims to the method result in additional advantages.
  • the invention includes the special use of the container pipes produced in this way as compressed gas cylinders, shock absorber container pipes or heat-insulated container pipes.
  • the great advantage of the invention is that the pipe section is positively connected to the bottom part. This creates a mechanically firm connection.
  • Another advantage is that the annular insert creates a gas-tight connection.
  • the pressure rollers which are easy to handle, are carried out at room temperature, which further simplifies production and above it also allows the use of heat-treated high-strength steel pipes. For example, pipes made of thermomechanically rolled sheet metal with a yield strength of over 600 N / mm2 can be used, which means that shock absorber containers can be made thin-walled to save weight.
  • the measure according to claim 2 is mainly suitable.
  • the pressure roll causes the destruction of a ring filled with adhesive.
  • the positive connection between the pipe end and the base part by the spinning roll is also generated in this case.
  • the basic idea of connecting the pipe end to the base part by spinning rollers can also be carried out with a soft, plastically deformable metal ring.
  • This alternative can be further developed in that the deformable metal enters into a solder connection with the material of the tube and the base part and the tube container produced by pressure rollers is briefly heated to the soldering temperature at the end.
  • the heating can also be connected to the production of a metallic corrosion protection layer on the roll container.
  • the metals aluminum, zinc, tin may be provided with an intermediate layer.
  • the manufacturing processes are of great importance for the production of compressed gas bottles, for example ethylene bottles, propane gas bottles, bottles for extinguishing agents. Because the manufacturing process can be used to produce particularly thin-walled pipe containers, the process is also important for the production of shock absorber container pipes.
  • the invention is not limited to the production of single-walled and cylindrical tube containers. It is also possible to produce tube containers from tubes with a polygonal cross-section, if only the end of the tube into which the base part is to be inserted is circular-cylindrical. For this purpose, a polygonal tube end can be formed in a circular cylindrical shape, or a circular cylindrical tube can be expanded polygonally to a short end.
  • multi-walled tube containers can also be manufactured.
  • the tube container shown in FIG. 1 consists of the tube 1 with the closed base 2 on the right in FIG. 1 and the partially open base 3.
  • the container is used as a stackable compressed gas container.
  • a reducing valve is screwed into the threaded opening 4 in the base 3.
  • the tube container body is a hexagonal tube section as it is produced by rolling or drawing.
  • the ends 5, 6 of the pipe section are brought into the circular cylindrical shape by pushing into a drawing ring.
  • the diameter of 5 and 6 is slightly smaller than the inscribed circle of the hexagon.
  • the bottom parts 5,6 have a radially open groove 7,8, in which a conventional O-ring 9 is inserted. They are pressed cold into the ends 5,6. So that they are already fixed in the pipe end for the next work step, they have an oversize compared to the clear width of 5 and 6.
  • the tube container 1 comes on the bench and is rotated.
  • a suitably profiled pressure roller possibly with a counter roller, is pressed in the area of the base parts 2, 3, so that a form-fitting connection between the tube body and the base part is created.
  • the assembly which is suitable for the respective purpose, for example the coloring, the screwing in of the fitting and the filling.
  • FIG. 3 Another embodiment of the tube container is shown in FIG. 3.
  • curved base parts 11, 12 are used and the protruding ends 10 of the circular cylindrical tube sections 5, 6 are rolled into the base parts during the pressure rolling.
  • This version is mainly intended for thin-walled pipe containers.
  • the pressure rolling of one of the circular cylindrical ends 5, 6 can also take place only after the installation of further parts, for. B. a piston with piston rod.
  • the tube containers are preferably circular cylindrical over the entire length.
