Definitions
- the invention relates to a container made of a helically bent metal strip, which can be used for example as a storage container for liquid or solid agricultural products or waste or biogas reactor.
- the manufacture of such containers is from the DE 2 250 239 A known.
- a coil with a diameter corresponding to the container diameter is formed from a sheet metal strip.
- the mutually associated helical Blechbandr is bent and then connected to each other on the outside of the container by means of a fold.
- Lipp double seam system manufacturing process a fast and easy production of containers with variable diameter and variable height is possible.
- transportable plate bending and assembly devices the container can be produced directly at the desired site.
- a container made of a helically bent sheet-metal strip in which a first edge portion is bent to form a helically extending Ausbiegekante to the outside. Also, the second edge portion of the sheet metal strip is bent outwards and on the outside by a fold connected to the first edge portion. In the vicinity of the joint of the angled edge regions, the sheet metal strip is welded to the inside of the container for the purpose of sealing.
- a container made of a helically bent sheet-metal strip, which has a first edge portion at the edge of the sheet-metal strip, which is bent towards the underside of the container.
- the sheet-metal strip of the known container also has a second edge portion, which is arranged on the edge of the sheet-metal strip over its entire surface in contact with the first edge portion. In that regard, the second edge portion overlaps the first edge portion to form the container wall and the attachment of additional welds in the container manufacturing can be dispensed with.
- the DE 20 2004 015 154 U1 relates to a container which is made of a helically bent sheet-metal strip with two edge portions designed to be complementary to each other so that an at least partially double-walled container can be welded from only a single sheet metal strip, for which a weld seam is provided both on the inside and on the outside of the container is provided.
- the invention is based on the problem of providing a container produced from a helically bent sheet-metal strip, which further increases the range of application of such containers, in particular has a large storage volume and / or increased mechanical stability, while still being simple and quick to produce.
- the container is made of a helically bent sheet metal strip, wherein the sheet metal strip has a first, helically extending edge portion, which is bent to form a helically extending Ausbiegekante towards the inside or to the outside of the container, and wherein the sheet metal strip a second Edge portion having, with respect to the longitudinal direction of the sheet metal strip opposite the first edge portion and also extending helically.
- the second edge portion of the sheet metal strip overlaps a third portion of the sheet metal strip, which is opposite to the first edge portion with respect to the bending edge and adjacent to the Ausbiegekante.
- the second edge portion and the third portion of the sheet metal strip are welded together in the region of the overlap, wherein the weld extends at least partially into the region between the second edge portion and the third portion of the sheet metal strip.
- the weld seam is preferably arranged in the region of the deflection edge, in particular, the deflection edge may be partially or even completely covered by the weld seam.
- the overlap of the third portion by the second edge portion is preferably a multiple of the sheet thickness of the sheet metal strip, in particular more than two times and preferably more than three times the sheet thickness.
- the overlapping of the third section by the second edge section takes place in the vertical direction.
- the first edge portion and the second edge portion each have the longitudinal edge of the sheet metal strip.
- the height of the weld is more than 100%, in particular more than 120% and preferably more than 150% of the thickness of the sheet metal strip, in particular the thickness of the sheet metal strip in the region of the bending edge.
- the sheet-metal strip preferably has a constant thickness over its entire extension in the longitudinal and transverse directions. The height of the weld seam ensures that the weld seam does not form a bottleneck for the force flow, so that it is ensured that the acting forces are reliably transferred from the third section via the weld seam into the second edge section without force in the region of the weld seam - and thus spikes occur.
- the height of the part of the weld extending in the region between the edge portion and the third portion of the sheet metal strip is more than 20%, in particular more than 25% and preferably more than 30% of the thickness of the sheet metal strip, in particular Thickness of the metal strip in the area of the weld.
- the welding takes place at least partially in the region of the bending edge, for example, the Ausbiegekante may be partially or even completely covered by the weld.
- the mechanical stability of the welded connection is further increased since the areas of the sheet-metal strip, which are stressed by the bending out, are melted in the area of the bending edge by the welded connection and become part of the welded seam after solidification.
- the weld extends into the area in which the second edge portion and the third portion are parallel to each other.
- the second edge portion and the third portion of the sheet metal strip may be parallel and in particular concentric with each other in the circumferential direction in the region of the overlap, and at the same time have a constant spacing or already abut each other. Both have a favorable effect on the stability of the welded joint.
- the second edge portion overlaps the third portion of the sheet metal strip on the inside of the container.
- the first edge portion may in this case be bent outwards, so that the Ausbiegekante is accessible from the outside and in particular the welding process can be done from outside the container to be produced. This considerably simplifies the production method, in particular because the welding device does not have to be transported out of the container interior to the outside after the end of the production of the container.
- the second edge portion is welded at its helically extending end edge to the third portion of the sheet metal strip. This welding can be done alternatively or in addition to the welding in the region of the bending edge. Insofar as the second edge section overlaps the third section on the inside of the container, the container is thereby closed in a fluid-tight manner on the inside and reliably prevents the formation of germ nests, which is particularly important in the case of food storage.
- an end edge of the second edge portion preferably forms on the inside of the container an obliquely or transversely to the vertical longitudinal axis of the container extending paragraph.
- the bending edge is formed by the first edge portion, which has been bent out toward the outside of the container, above of the opposite with respect to the longitudinal direction of the sheet-metal strip second edge portion is arranged.
- the deflection is substantially rectangular and the length of the scalloped portion in one embodiment is more than two times, more preferably more than three times and preferably more than five times the thickness of the sheet metal strip. As a result, the mechanical stability of the container is increased.
- radially outwardly projecting first edge portion also the outside weld can be particularly easily mounted, in particular, the welding apparatus at an acute angle of preferably more than 20 ° and less than 70 ° relative to the horizontal to the joint of the second edge portion and be guided out of the bending edge, so that in a simple manner, a sufficiently deep weld and thus a sufficiently stable weld can be made.
- the third section of the sheet metal strip adjoining the bending edge in the direction of the second edge section is bent out by an offset relative to a fourth section of the sheet metal strip adjoining the offset in the direction of the second edge section, in particular bent out toward the outside of the container.
- the mutually associated edge portions of the sheet metal strip can be brought into abutment without or with reduced mechanical stresses.
- the second edge portion can be supported on the arranged between the third section and the fourth section crank, which on the one hand further simplifies the production and the stability is increased and on the other hand a precisely fitting Connection is guaranteed.
- the offset caused by the offset radial offset of the second edge portion relative to the fourth portion of the sheet metal strip is less than 95% of the thickness of the sheet metal strip, in particular less than 90% and preferably less than 85%.
- the two mutually associated edge portions are slightly elastically deformed during manufacture of the container and are characterized in biased contact with each other. This leads to a further stiffening of the container.
- the second edge section is preferably bent into the interior of the container by a further offset relative to a fifth section of the sheet-metal strip adjoining the offset in the direction of the first edge section.
- the offset can lie in the region of the radially outward deflection edge of the first edge section.
- the offset caused by the offset radial offset of the second edge portion relative to the fifth section may be less than 95% of the thickness of the sheet metal strip, in particular less than 90% and preferably less than 85%.
