Definitions

  • the invention refers to a anti-bending stepped 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 anti-bending 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.
  • the container 1 when expanding suffers a bending deformation 2 which causes an uneven distribution of the material across the periphery of the container 1 itself so that to continue with the manufacturing of the container it is necessary to correct such bending 2 in order that the whole periphery of the container is parallel and the "a" deformation disappears.
  • Such disappearance or correction of the bending is achieved by means of a series of steps 3 the number of which depends on the size of the deformation "a" referred to above. Such steps are located at or affect specific areas as shown in figures 1 and 2 and all have the same dimension which corresponds to the size of the steps "b" so that such steps 3 fold the excess material at those areas where they have been made.
  • the correction achieved with the steps 3 on the wall 4 of the container 1 with respect to the wall 4' with no steps can be compared in figure 3.
