Description

  

      Wellblech.       Bei vielen     Gegenständen,    die aus Well  blech hergestellt werden, ist es häufig erfor  derlich oder zum mindesten erwünscht, den  Rand des Bleches an den beiden gewellten  Enden in die- geradlinige Form zu bringen.  Man hat diese Aufgabe auf verschiedenerlei  Weisen, insbesondere durch Aufschneiden der  Enden und Zusammenlöten oder -schweissen  der Blechlappen mit oder ohne Einfügung  besonderer Blechteile, gelöst.  



  Nach der     Erfindung    wird die nicht wellen  förmige Randlinie durch Zusammenquetschen  der Blechwellen gebildet.  



  In der Zeichnung sind zwei Ausführungs  beispiele für den Erfindungsgegenstand, sowie  ein     Werkzeug    zu seiner Herstellung- darge  stellt.     Fig.    1 zeigt den Querschnitt des der       Zeichnung    zu Grunde liegenden Wellbleches,  dessen Wellen scharfkantig angenommen sind,  um das Blech im Aufriss     (Fig.    2 und .5)  deutlicher veranschaulichen zu können.

   Gemäss  der Ausführungsform nach     Fig.    2 bis 4, von  denen     Fig.    2 eine Ansicht von vorn,     Fig.    3  eine Draufsicht auf die obere Blechkante  und     Fig.    4 einen Längsschnitt zeigt, sind die  Wellen am Rand seitlich umgelegt und in    Falten zusammengequetscht, deren geradlinige  obere Kante a hier beispielsweise in die  Mittelebene     M-M    der Wellen verlegt ist.  



  Nach     Fig.    5 bis 7, die ebenfalls Ansicht  von vorn, Draufsicht und Längsschnitt ver  anschaulichen, sind die Wellen am Rand a  in taschenförmige, symmetrische Doppelfalten  gequetscht, wobei die obere Kante in einer  Ebene     T=T    liegt, welche die Wellen des  Bleches tangiert. Zwischen der Kante a und  dem Beginn des wellenförmigen Teils des  Bleches ist ein glattes,     ebengepresstes    Stück  von der Höhe f eingeschaltet.  



  Weitere Arten der Zusammenfaltung an  der Blechkante sind möglich und ergeben sich  aus dem bisher Beschriebenen ohne weiteres:  Die Herstellung des Wellenabschlusses  nach der Erfindung kann durch einen nach  der gewünschten     Abschlussform    gebildeten       Pressstempel    erfolgen, und zwar mit oder  ohne Matrize. Ein solcher Stempel zur Her  stellung einer Blechkante nach     Fig.    5-7 ist  in den     Fig.        ss    und 9 der Zeichnung dargestellt.  Der Stempel selbst ist mit     c    und das zu  bearbeitende Blech mit b bezeichnet, während      statt einer Matrize eine glatte Platte d Ver  wendung findet. Im Stempel c finden sich die  Ausschnitte e, die der Blechform entsprechen.



      Corrugated iron. With many objects that are made from corrugated sheet, it is often necessary or at least desirable to bring the edge of the sheet at the two corrugated ends in the straight shape. This object has been achieved in various ways, in particular by cutting open the ends and soldering or welding the sheet metal tabs together with or without inserting special sheet metal parts.



  According to the invention, the non-wave-shaped edge line is formed by squeezing the sheet metal waves.



  In the drawing, two execution examples for the subject of the invention, and a tool for its production are Darge. 1 shows the cross section of the corrugated sheet metal on which the drawing is based, the corrugations of which are assumed to be sharp-edged in order to be able to more clearly illustrate the sheet metal in elevation (FIGS. 2 and 5).

   According to the embodiment according to FIGS. 2 to 4, of which FIG. 2 shows a view from the front, FIG. 3 shows a plan view of the upper sheet metal edge and FIG. 4 shows a longitudinal section, the corrugations are folded over at the edge and squeezed together in folds straight upper edge a is moved here, for example, in the central plane MM of the waves.



  According to Fig. 5 to 7, which also illustrate the front view, top view and longitudinal section ver, the waves are squeezed at the edge a in pocket-shaped, symmetrical double folds, the upper edge lying in a plane T = T, which is tangent to the waves of the sheet . Between the edge a and the beginning of the wave-shaped part of the sheet a smooth, even-pressed piece of height f is inserted.



  Other types of folding at the sheet metal edge are possible and result from what has been described so far: The shaft termination according to the invention can be produced by a press die formed according to the desired termination shape, with or without a die. Such a stamp for producing a sheet metal edge position according to Fig. 5-7 is shown in Figs. Ss and 9 of the drawing. The punch itself is designated with c and the sheet to be processed with b, while instead of a die, a smooth plate d is used. In the punch c there are the cutouts e that correspond to the sheet metal shape.
