Definitions

  • the document DE-A-1 953 746 which contains the features of the preamble of independent claim I, discloses the production of sheet metal walls of variable dimension, such as door leaves, in particular one-piece door leaves (tilting gates), container walls or the like, which are guided over head a plurality of sheet metal webs that are continuous in terms of their length and that are composed in terms of their width by folding along the longitudinal edges, two of which are formed in the central width region of the sheet metal walls with the formation of a groove-shaped bead - within which a door leaf lock may be arranged - or three, one of which is centrally located in the central width area of the sheet metal walls , are butt-jointed and, on their long sides facing away from the center of the width, have connections arranged in regions of further groove-shaped beads to each further sheet metal sheet which follows in the width direction in an optically symmetrical manner, so that - usually with the formation of further, at least similarly designed and longitudinal, groove-shaped beads equally spaced within the sheet metal surface itself - there is a
  • the invention has for its object to enable the production of sheet metal walls, in particular one-piece overhead door leaves, different width dimensions in the most economical manner possible.
  • door leaves are, above all, so-called tilting door leaves, i.e. one-piece door leaves that can be moved overhead, as sheet metal walls, which is basically done by rebated connections and / or spot welding. This also applies to the outer edge connection of such a sheet metal wall to a frame, which in turn is deformed from a sheet metal strip into a hollow profile and can be connected to the door leaf wall with a folded edge region.
  • this object is achieved according to the invention in that on both sides of the sheet metal sheets arranged broadly symmetrically and, if appropriate, further sheet sheet sheets which are subsequently provided, such reduced width dimensions are connected, which adjust the totality of the sheet metal sheets in their width composition to the desired Supplement the width dimension of the sheet metal wall to be produced in each case, all sheet metal sheets being removed from a sheet metal coil coil of a predetermined width and the sheet metal sheets on the wide edge being optionally trimmed to the respectively required reduced width dimension parallel to their longitudinal direction.
  • the door leaf or sheet metal wall which is of practically any height and above all wide, can be produced in general from a single sheet of sheet metal which has a certain, in particular commercially available or other width which is particularly predestined for the use in question.
  • the sheet metal walls or door leaves are first connected in a conventional manner parallel to their longitudinal edges with fold connections known in this connection, whereupon to compensate for the missing remaining width in a play-symmetrical arrangement to the longitudinal center of the sheet metal wall or the door leaf, two each provided on the broad edge and adapted to size narrower sheet widths are connected, which are obtained from the sheet web of the same width or subtracted from the same sheet web coil.
  • the wide-edge webs which are generally narrower than the other sheet metal webs located between them, are preferably designed in terms of connection technology in such a way that they are formed by clip-like folds by a type of hooking process, at least with the subsequent, correspondingly shaped longitudinal edges of the adjacent metal webs of customary width and preferably also have it connected to a frame surrounding the sheet metal wall or the door leaf.
  • the symmetrical division of the width of the door leaf or the sheet metal wall can be such that a sheet metal sheet forms the central longitudinal region, but in a preferred embodiment, the longitudinal center of the door sheet or the sheet metal wall can be centered through the groove base of a sheet metal sheet connected between two by folds or the like run.
  • these are preferably embossed in themselves with longitudinal groove-shaped beads which correspond to those in the transition area between two adjacent sheet metal sheets.
  • a particularly material-saving and easy-to-handle production is achieved in that the sheet metal sheets - at least those sheet sheets of uniform size located outside the wide-edge sheet and generally narrow sheet sheets - are limited in at least one of their longitudinal edge areas in the middle of the groove base of the bead transition to the adjacent sheet sheet.
  • the sheet metal strip unwound from the coil is fed to a feed straightening machine 3 with a subsequent cross-cutting shear 4, if necessary via a spacing section which allows the formation of a band loop.
  • the band loop formation at 2 is necessary when the shears 4 are not running, if one wants to avoid intermittent rotation of the reel 1.
  • sheet metal webs - are fed to a transport roller table 5 which has three removal directions, one of which is used for the removal of rejects and the second of which leads to a profile forming machine 6, in which the width of the sheet metal from the Sheet metal strip unchanged normal sheet metal strips are profiled (formation of beads).
  • profiled sheet metal webs pass through a transport table 7 to an angle table 8, from which they are fed at a right angle and thus perpendicular to their longitudinal direction to a bending press 10 and then to a separating and folding machine 11 and a punching station 12 by means of feed buttons 9.
  • the sheet metal webs which are cut to the desired door leaf height by the cross-cutting shears 4 and are determined in the profile forming machine 6 according to the desired profile, are bent, folded and punched at 12 with regard to any material breakthroughs - e.g. lock receptacle - and punched and passed on to a transport and transfer table 13 and then to an assembly station 14 as far as prefabricated sheet metal wall except for the lateral edge sheet webs.
  • a front stop 15 and guillotine shears 16 with scrap disposal 17 are connected to a third exit of the transport roller table 5.
  • the desired width of the normal width delivered by the cross-cut shears 4 is branched off and cut in adaptation to the desired sheet metal wall width.
  • Relatively narrow side sheet metal strips for example 10 cm wide, may be required to create a 2.10 m wide door leaf (sheet metal wall). Therefore, a corresponding amount of side sheet webs of smaller width can be obtained from a branched sheet metal sheet. In doing so, and also in the sense of a batch-wise creation of side sheet webs, it can be useful to provide a store, for example a paternoster store, behind the guillotine shear 16.
  • the side sheet webs obtained in this way which are generally significantly narrower than the normal width sheet metal webs (filler sheets), are moved laterally with the aid of feed tongs, i.e. transported in their longitudinal direction and fed to a notching, separating and feed station 19, from where they are fed to a special profile forming machine 20 for profiling the side sheet webs.
  • a corrugation - 26 in FIG. 2 - which fits into the grid dimension of the desired finished sheet metal wall can be made here, but in particular the profiling is provided for connection to the partial sheet metal wall supplied preparatively in the assembly station, as is the case in connection with the following figures will be explained later.
  • the side sheet webs preparing for the connection are produced and can now be fed to the assembly station 14 in different ways; In the exemplary embodiment according to FIG. 1, this is done in such a way that the side sheet webs are advanced perpendicularly to their longitudinal direction via a transverse transport table 21 and rotated 180 ° over the other by means of a turning station 22. Accordingly, side sheet conveyors arrive in the assembly station 14 via feed roller conveyors 23 in a suitable connection assignment and are there connected to the sheet metal wall prefabricated from the normally wide sheet metal sheets, so that the complete desired sheet metal wall is present.
  • the above work processes are controlled automatically after entering the desired sheet wall height and sheet wall width with regard to the cut and the delivery rhythm.
  • FIG. 2 shows a partial cross section which shows two adjacent sheet metal webs with their connection point in the area of a groove simulation 27; the sheets themselves are provided with groove-shaped beads 26, the cross-sectional shape of which corresponds approximately to the groove simulation 27.
  • the solid line guide represents a fold connection, as is preferably provided between two normal width middle sheet webs (filler sheets) 24.
  • the sheet metal sheet shown on the left is cut approximately in the central groove area and folded over with respect to its folded edge area forming half the groove bottom, as shown in dashed lines and the associated arrow.
  • the edge region of the left sheet-metal web 24, which serves for the folding, is, on the other hand, wider, so that the fold shown in FIG. 2 can be produced.
  • FIGS. 3 and 4 show other connections which enable two adjacent sheet metal webs to be “hooked in”.
  • a suspension loop is formed on a side sheet web 25, the insertion direction of which runs approximately parallel to the sheet metal wall plane, as shown in FIGS. 3 and 4.
  • hooking edges 30 are pushed, which are either formed by bent folding edges 28 of the sheet metal webs or by an intermediate sheet metal strip 31, which is integrated in the area of an edge in a fold formation similar to that according to FIG. 2 and with its other edge area the hanging edge 30 for the insertion into the suspension loop 29 forms.
  • a bent fold edge area 28 is also shown in dashed lines. This is to indicate that the fold formation is possible both in the right and in the left area of the replica 27.
  • Figures 3 and 4 are also mirror-symmetrical depending on the side edge area considered.
  • the hanging in, in particular of the side sheet metal webs makes it unnecessary to fold in this area and makes assembly easier, especially in the event that the sheet metal wall is inserted into a frame, as is the case with a door leaf of a tilting door.
  • the sheet metal wall, in particular in the area of the side sheet webs can also be fixed by a kind of hanging process on the folded edges of the hollow sheet metal frame projecting towards the sheet metal wall, stabilized if necessary by a spot welding process or similar locking aid.
