  Nach Beendigung der Wellenbildung       wird    der Blechstreifen längs der mittleren  Mulde g um<B>18'0</B>   in zwei     Hälften    gegenein  ander gebogen, so dass<I>die</I> Mulden<I>i, k</I> und     in     an die Mulden e, c und a und die rechte       Längskante    a an die linke Längskante anzu  liegen kommen. Die beiden     Endränder    wer  den dann     übereinander    gebördelt und -ver  schweisst oder verlötet.  



  Die     Pressvorrichtung        gemässi        Fig.4    zur     Aus-          führung    der Wellenbildung, von welcher in  der     Zeichnung    nur die zum Verständnis. der  Erfindung     unbedingt    erforderlichen Teile  dargestellt sind, besitzt eine untere, auf einem  Sockel 3     fest    gelagerte     Matrize    2, sowie einen       beweglichen    Teil mit einem Formträger 4, in  welchem vertikal verschiebbar die Form  stücke 5, 6, 7, 8, 9 gelagert sind, deren       Längsränder    parallel zueinander sind.

   Durch  Längsschlitze 11 dieser Formstücke geht ein  Querbolzen 10 hindurch,     und    zwar nimmt  die Länge der Schlitze vom mittleren Form  stück 7 gegen die     beiden    äussern Formstücke  5 und 9 hin ab und die Schlitze sind in  Längsrichtung     gegeneinander    versetzt, so  dass, in der Ruhestellung der Formstücke    deren     Arbeitskanten        dachziegelartig    abge  stuft sind, wobei die     Arbeitskante    des mitt  leren     Formstückes    7 die     tiefste    ist.

   Die       Formstücke    werden in dieser Stellung durch  Federn 12 gehalten, welche in dem am obern  Teil     des    Formträgers     befestigten    Block 13  gehalten sind.  



  Die Wirkungsweise dieser     Pressvorrich-          tung    ist folgende:  Nachdem der Blechstreifen a,     n    wie aus       Fig.    4 ersichtlich auf die Matrize .gelegt wor  den ist, wird .der Formträger 4, welcher den       Pressstempel    bildet, auf     hydraulischem    oder       pneumatischem    Wege oder auf irgend eine  andere Weise abgesenkt.

   Nun trifft     das.    mitt  lere     Formstück    7 auf den Blechstreifen a,     ra,     auf und bildet eine mittlere Welle f, g,     h,     bevor die nächstfolgenden Formstücke 6 und  8 ihrerseits auf das Blech auftreffen, so     dass          .das        letztere    auf jeder Seite des mittleren  Formstückes nachgeben kann, um die Län  gendifferenz zwischen der Summe .der beiden  Seiten f, g und<I>g, h</I> und der Länge f,     h        aus-          ucieie,    Nach     Bildun-,    der mittleren  z<B>Z></B>     lien.   <B>C</B>  Welle<I>f, g,

Während dieses Vorganges werden die Form  stücke, welche die Bildung der unter ihnen  liegenden Wellen bereits ausgeführt haben,  durch ihre Federn in ihrer Lage gehalten,  um die Blechtafel<I>a, n</I>     in    ihrer richtigen  Lage zu     halten    und eine Deformation der be  reits gebildeten Wellen zu verhindern.  



  Die beiden letzten     'Wellen   <I>b, c, d</I> und       1c,   <I>l</I> werden zuletzt durch die     Formstücke    5  und 9     gebildet.    Sobald die     Formstücke    die  Bildung der Wellen im Blech beendigt haben,  liegen     dieselben    unmittelbar am Block 13 an  und nun kann der Formträger durch hartes       [email protected]    auf die Matrize 2 die -Wellen  fertig pressen,     wobei    die Formstücke in glei  cher Weise wirken, wie wenn sie aus einem  Stück mit dem Formträger 4 wären.  



  Anstatt dreieckig     wie    dargestellt     könnte     die     Wellung    auch mit anderem Profil, z. B.      polygonal, halbkreisförmig,     elliptisch        usw.     ausgeführt sein.



  Hollow structure with corrugated walls, in particular a radiator element, and a method and device for producing the same. The present invention relates to a hollow structure with corrugated walls, in particular a radiator element, and a method and a device for producing the same.



  The hollow structure according to the invention is characterized in that @ it consists of a single corrugated sheet metal strip, which is bent together around a central trough in such a way that the waves lying opposite one another in pairs are juxtaposed prisms or. Form cylinders, and that the free end edges are tightly attached to one another.



  The method according to .the invention for the production of such a hollow structure consists in "that one bends a sheet metal strip well len-shaped, bends around a central fold and the transverse edges of the sheet metal strip are united and sealed.



  The invention also relates to a device for performing this method. The device for wave-shaped bending of a sheet metal strip according to the inven tion has a press die with a number of parallel shaped pieces which are formed so that they exert their pressing action one after the other during pressing and are held firmly in their pressing position by springs.



  Thanks to the use of such a device for wave-shaped bending of the sheet metal strip, there is no stretching of the sheet metal, so that very thin sheet metal can be used.



  An exemplary embodiment of the hollow structure according to the invention, the various phases of the manufacturing method according to the invention, and an exemplary embodiment of the device for carrying out this method are shown in the drawing, namely: FIG. 1 shows a sheet metal strip in vertical section;

             Fig. 2 shows a section through the sheet metal strip provided with corrugations; Fig. 3 shows a vertical section through a hollow structure formed from the corrugated sheet metal strip; Fig. 4 shows a vertical section through a press device.



       The hollow structure shown in Fig. 3, a cooler element, which is seen in section, is formed by three juxtaposed prisms united at their longitudinal edges along the plane indicated by the line XX, is made of a sheet metal strip <I> a, n </I> produced (Fig. 1), the length x of which corresponds to the sum of the lengths of the sides ab, bc of the prisms. In this sheet metal strip a,

       Now, waves are formed, as can be seen from FIG. 2, and this wave formation takes place without any stretching of the metal. The 'wave shaping can be done in the press described below.



  After the corrugation has ended, the sheet metal strip is bent along the middle trough g by <B> 18'0 </B> in two halves against one another, so that <I> the </I> troughs <I> i, k </ I > And come to rest on the troughs e, c and a and the right longitudinal edge a on the left longitudinal edge. The two end edges who then crimped and welded or soldered on top of each other.



  The pressing device according to FIG. 4 for executing the wave formation, of which only the one for understanding in the drawing. the invention absolutely necessary parts are shown, has a lower, fixedly mounted on a base 3 die 2, and a movable part with a mold carrier 4, in which vertically displaceable the mold pieces 5, 6, 7, 8, 9 are mounted, the Longitudinal edges are parallel to each other.

   A transverse bolt 10 passes through the longitudinal slots 11 of these fittings, namely the length of the slots decreases from the middle form piece 7 against the two outer fittings 5 and 9 and the slots are offset from one another in the longitudinal direction so that, in the rest position, the fittings the working edges of which are tiered like tiles, the working edge of the mitt sized molding 7 is the deepest.

   The mold pieces are held in this position by springs 12 which are held in the block 13 attached to the upper part of the mold carrier.



  The mode of operation of this pressing device is as follows: After the sheet metal strip a, n has been placed on the die as shown in FIG. 4, the mold carrier 4, which forms the press ram, is hydraulically or pneumatically or any other way lowered another way.

   Now the middle shaped piece 7 meets the sheet metal strip a, ra, and forms a central wave f, g, h before the next shaped pieces 6 and 8 in turn hit the sheet metal, so that the latter on each side of the middle The fitting can yield to the length difference between the sum of the two sides f, g and <I> g, h </I> and the length f, h aus- ucieie, according to education, the middle z <B> Z > </B> lien. <B> C </B> wave <I> f, g,

  </I> 1i, the neighboring corrugations <I> d, e, f </I> and lt, i.,, J are formed in the same way, with the sheet metal strip between the corrugation and the edge < I> a </I> or n shortened accordingly with each wave formation. During this process, the shaped pieces, which have already carried out the formation of the waves lying below them, are held in their position by their springs in order to keep the sheet metal in its correct position and prevent deformation to prevent the waves that have already formed.



  The last two 'waves <I> b, c, d </I> and 1c, <I> l </I> are finally formed by the shaped pieces 5 and 9. As soon as the shaped pieces have finished the formation of the corrugations in the sheet metal, they lie directly against the block 13 and now the mold carrier can finish pressing the corrugations onto the die 2 through hard [email protected], the shaped pieces acting in the same way, as if they were made of one piece with the mold carrier 4.



  Instead of being triangular as shown, the corrugation could also have a different profile, e.g. B. polygonal, semicircular, elliptical, etc. be executed.
