Definitions

  • the invention relates to a method for the production of rectangular sheet metal shells, in particular for pallet containers with an inner container made of plastic with a rectangular outline, in which the narrow sides of a rectangular sheet metal blank are folded over to form a double fold edge, the sheet metal blank is bent into a tubular body which adjoins after bending the sheet metal blank Double rabbet edges are hooked together, after which the tubular body is pulled over the expanding jaws of a stretching press, the expanding jaws having the shape of the narrow sides of the sheet metal jacket to be produced, and stretching the expanding body of the tubular press until the sheet metal material flows and thereby being strain-hardened.
  • the invention has for its object to further develop the generic manufacturing process with a view to a minimal scrap rate and the saving of expensive welding machines.
  • the manufacturing method according to the invention enables such a firm connection of the abutting edges of the tubular sheet metal blanks that tearing of the sheet metal jackets at the connection points during the stretching process is ruled out, and eliminates the need for expensive welding machines by eliminating the weld seams of the tubular bodies as starting products for the sheet metal jackets.
  • the pallet container 1 used as a single-purpose and multi-purpose container according to FIG. 1 for the transport and storage of liquid goods has as its main components an interchangeable inner container 2 made of polyethylene with a rectangular outline and rounded corners, which has a filler neck 3 which can be closed by a screw cap 4 and a tap 5 is equipped with a sheet metal jacket 6 with a removable sheet metal cover 7 and a pallet 8 made of sheet metal as a flat base pan 9 with length and width dimensions in accordance with Euro standards for the positive reception of the plastic inner container 2.
  • a series of spaced connecting tabs 16 are formed by cut embossing outwards parallel to the double fold edges 11a, 12a, and the double fold edges 11a, 12a are formed by a wire 17, the ends 17a of which are drawn through the connecting tabs 16 , 17b are fastened to the two outer connecting straps 16a, 16b, locked against one another (FIGS. 3-5).
  • the tubular body 15 is drawn onto a stretching press 18, the expansion jaws 19 of which have the shape of the narrow sides 2a, 2b of the plastic inner container 2.
  • the tubular body 15 is aligned such that the hooked double fold edges 11a, 12a of the tubular body 15 are located in the area of an expanding jaw 19 of the stretching press 18.
  • the tubular body 15 assumes the shape of the sheet metal jacket 6.
  • the tubular body 15 made of sheet metal or the resulting sheet metal jacket 6 acts like a brake hand, so that the broad sides 21 of the sheet metal jacket 6 are mainly stretched, since the spreading jaws 19 are pressed apart so far that the sheet metal material in the wide sides 21 is light is made to flow and even a slight "saber effect" is produced in these broad sides.
  • the sheet metal jacket 6 is given such a final shape that it fits tightly against the inner plastic container 2 and receives maximum stability with the smallest possible sheet thickness. Furthermore, material can be saved by stretching the sheet metal jacket 6 in the rectangular sheet metal blank 10, and no complicated and expensive special press with large press molds is required for the shaping of the sheet metal jacket 6.
