Definitions

  • the invention refers to a anti-bending corrugating system for metallic containers, the aim of which is to prevent the usual bending that normally appears in the metallic containers during the expansion operations carried out to obtaining or manufacturing such containers.
  • the corrugating system can be applied to all kind of metallic containers of a shape that can be either trunco-pyramidal, parallelopipedic, elliptical, etc.
  • the first one consists of cutting the material with its periphery already compensated prior to proceed to weld the body and its subsequent expansion.
  • the second system consists of expanding the body of the container with concave expanding tools so that they can proportionately compensate the subsequent deformation.
  • the system proposed has been conceived to satisfactorily solve all those problems on the basis of a simple and efficient solution which the added advantage - when compared with the first conventional system referred above - of a better use of the raw material which, in turn and compared with the second conventional system, enables to obtain a more even and straight configuration of the wall of the container which makes the storage of the containers much easier.
  • Figure 1 shows a schematic view of the side of a container.
  • One of the halves incorporates the preconized corrugations and the other half is shown without such corrugations and presents the relevant corrugations.
  • Figure 2 shows a plan view of a rectangular container with corrugations in one of its corners.
  • Figure 3 finally shows a section view of the corrugations made on the wall of a container presenting the compensation of excess material compared with the non-corrugated wall shown in the same figure.
  • Such disappearance or correction of the bending is achieved by means of a series of corrugations, specifically two corrugations (3), one opposite to the other, although their number will depend on the size of the bending (2).
