Definitions

  • the invention relates to a container made of thin-walled material, in particular made of steel and aluminum sheet, with beads molded into the fuselage, and a tool for producing high-precision fine beads on thin-walled sheet metal containers.
  • Beads serve to increase the strength of the container in the axial and / or in the radial direction. All-round beads increase the collapse resistance when evacuating the containers and during the cooking process in the autoclave. Such all-round sikken are now used in large quantities on cans for food.
  • Containers are also known from the literature, in particular large containers with a volume of 200 liters, in which the surrounding beads are inclined to the horizontal or run in a helical shape (GB PS 973,373 and 978,982).
  • Another object of the invention is to provide a sikken training which allows the use of thinner, in particular double-reduced sheet metal and aluminum sheet.
  • a tool for producing the precision beads is defined in the characterizing part of claim 13.
  • the circumferential beads which are designed to be much finer and with a small mutual distance, but in particular absolutely precise and parallel over the entire circumference, give the container an axial strength that is above the previous values.
  • the collapse resistance of the known bead designs is not undercut, but even exceeded. Additional axial strength is provided by some gently running axial beads.
  • a further increase in strength is achieved by helical, elliptical or wavy beads.
  • the extremely fine beads allow the processing and consequently the use of cheaper double-reduced sheet, which is known to be much harder than simply reduced decorated sheet metal, or it can also be used aluminum sheet of small thickness for canned containers.
  • double-reduced sheet metal also makes it possible to use thinner sheet metal with the same strength.
  • a further advantage of the invention consists in that the ends of the helical beads merge into the undeformed area of the fuselage without a step, thereby eliminating weak points at which buckling can begin.
  • the strength can be further increased by alternately different ends of the beads running into the undeformed areas.
  • Another advantage of the invention is that when the beads are produced with the tools described, the torsion is tightened in a rotationally fixed manner, the container body remains completely round, as a result of which the force curve is later evenly distributed within the body of the sealed can.
  • Another advantage of the invention is that the mutual spacing of the beads and their depths towards the center of the fuselage become too small and / or deeper, or outwards (towards the bottom or lid) further and / or less deep , whereby additional stiffening can be achieved in this area of greatest pressure hazard.
  • the precise, synchronously rolling tools form absolutely precise, reproducible fine beads of the highest mutual parallelism on the torsionally fixed body. This results in an absolutely even course of the axial and radial forces over the entire circumference of the fuselage. This eliminates weaknesses where buckling can begin.
  • the axially parallel beads additionally increase the axial strength without having an impact on the collapse strength.
  • a circular base 1 and cover 2 made of sheet metal are placed in a conventional manner on a circular cylindrical fuselage 4 also made of sheet metal and fastened there, whereby a tin can 3 is formed.
  • a tin can 3 is formed in the fuselage 4, which has to absorb the radially inward or outward forces F, in particular during and / or after the cooking process for canned goods, and the axially acting force F a during storage, circumferential beads 5 running perpendicular to the cylinder axis are provided (FIG. 1).
  • the conventional tin can 3 can have a coherent bead group in the central region of the fuselage 4 or can be divided into several bead groups.
  • the fuselage 4 can be produced by welding, soldering, deep drawing or stretching.
  • the distance d between the individual beads 5 is very large in relation to their depth h, usually d is at least 4.0 mm and h is at least 0.7 mm for a can of 73 mm diameter and 0.19 mm sheet thickness.
  • the flanks between the bead base and the crest of the bead are essentially straight and form inclined planes.
  • the parallelism of the beads is often not constant along the circumference. This results in different radii on one and the same bead, combined with a resulting reduced strength.
  • FIG. 3 shows a fuselage 6 manufactured according to the invention with a bottom 7 and a cover 8.
  • very fine, high-precision beads 10 are embossed, the radii of which are the same at the top of the bead and at the bottom of the bead, and whose mutual distance is absolutely constant over the entire circumference.
  • the beads lo vertical, substantially axially parallel beads 11 are superimposed.
  • the beads 11 leave the crest of the beads unaffected, but on the other hand partially reduce the depth of the base of the beads by 20 to 50% of the depth h of the surrounding beads.
  • the axial beads 11 run over the entire beaded area.
  • Beads with an analogous cross section are shown in FIG. 6.
  • the beads 14 are formed in a helical shape, in the example shown in a multi-course arrangement.
  • the ends 15 of the beads 14 run continuously and without the formation of an angular transition into the undeformed areas 16 and 17.
  • three further beads 14 are indicated by dot-dash lines. It may be advantageous to make the beads 14 closer together and / or slightly deeper in the central area.
  • Vertical beads 18 are also superimposed on the helical beads 14 in this example.
  • the ends 15 'of the sikken 14 can alternately run a little further into the undeformed areas 16, 17 (broken lines
  • corrugations 2o running around in a wave shape with a cross section analogous to the above-described beads 10 and 14 are embossed on a can body 19.
  • Vertical corrugations 21 are superimposed on the wavy corrugations 2o.
  • the distance d between the beads lo, 14 and 2o is preferably approximately 2.0 to 3.9 mm for a sheet thickness s of 0.15 mm.
  • the depth h of the deformation is approximately 0.4 to 0.8 mm, the upper values being more advantageous for double-reduced sheet metal and the lower values being more advantageous for single-reduced sheet metal.
  • FIG. 8 shows a tool set for producing the helical beads 14 from FIG. 6.
  • Both tools both the inner tool 23 consisting of segments 22 and the outer tool 24 which can be displaced radially to the inner tool, have ribs 25 and 26 on the lateral surface. These ribs 25, 26 are fine, extremely precisely formed elevations with cleanly rounded shoulders.
  • the ribs 26 can have a larger radius than the ribs 25, so that the radii R of the bead curvatures inside the can are larger and thus the load on the coating is lower (fig. 9).
  • the vertical beads 18 can be created by vertically superimposed interruptions in the ribs 25 and / or 26 (not shown on the tools 23, 24). In the example according to FIG. 8, the vertical beads 18 are produced by the gaps 27 which result when the segments 22 are spread, the depth of the axially extending beads 11, 18, 21 between 20 and 50% of the height h of the peripheral beads 10.14. Is 20.
  • the tools must be provided with corresponding shaped ribs 23,24 for the bead embodiments according to Figures 3 and 7 '.
