Description

  

  Vorrichtung zur Herstellung von     Profilrändern    an Blechen.    Die Erfindung betrifft eine     Vorrichtung     zur stufenweisen Herstellung von Profil  rändern an Blechen, insbesondere solchen mit  gekrümmt verlaufenden Formen, mittels  Formwalzen, die über zweiteilige, das Blech  zwischen .sich festhaltende Schablonen laufen,  während diese über den Formwalzen gegen  über angeordnete Stützwalzen hinweggeführt  werden. Bei den bekannten Vorrichtungen  dieser     Art    sind die Formwalzen für die ein  zelnen Arbeitsstufen gleichachsig auf einer  gemeinsamen Welle angeordnet.  



  Gemäss der Erfindung sind dagegen die  Formwalzen für die einzelnen Arbeitsstufen  am Rande einer kreisförmigen Scheibe ge  lagert. Dies hat den Vorteil, dass das Werk  stück viel schneller als bisher hergestellt wer  den kann, da das Drehen der die     einzelnen     Walzen     tragenden    Scheibe     schnell    vonstatten  gehen kann und, ein Umspannen des Werk  stückes für die folgende Arbeitsstufe in Fort  fall kommt. Die Vorrichtung kann auch  kleinere Abmessungen in der Tiefe haben, da    die Anordnung der Formwalzen auf der  kreisförmigen Scheibe viel weniger Platz ein  nimmt als die bisherige Ausführung. Durch  den Fortfall der die Walzen tragenden, ver  hältnismässig langen Welle wird auch die  Unfallgefahr vermindert.  



  Auf der     Zeichnung    ist     ein    Ausführungs  beispiel des     Erfindungsgegenstandes    dar  gestellt, und zwar zeigt     Fig.    1 eine Scheibe 1,  auf der Formwalzen 2 am Rand auf zapfen  artigen Vorsprüngen     ä    drehbar gelagert sind.  Die Form der Walzen 2 ist, auf den Quer  schnitt bezogen, so gewählt, dass jede     einzelne     Walze     eine        fortschreitende    Arbeitsstufe be  stimmt, welche immer mehr der     gewünschten     Fertigform des zu     bearbeitenden    Blechteils  gleichkommt.  



  Die     Fig.    2 zeigt die ganze     Vorrichtung     schematisch teilweise im     Schnitt.    Die Scheibe  1 ist um die Achse 4 drehbar angeordnet und  kann mit einer     Feststellvorrichtung    5 in be  stimmten Lagen festgehalten werden, so dass  immer die dem notwendigen Arbeitsgang ent-           sprechende    Walze zum Einsatz kommt. Die  zu bearbeitenden Bleche 6, 6' werden zwi  schen zwei     Schablonenteilen    7 und 7', die aus  Holz oder ähnlichem Werkstoff bestehen  können, eingeklemmt und auf die Leitrolle 8  aufgesteckt. Diese ist auf der Welle 9 starr  befestigt, während die Rolle 10 drehbar auf  der feststehenden Achse 11 angebracht. ist.

    Die Rolle 10 ist     achsial    in Pfeilrichtung ver  schiebbar, damit die Bleche 6, 6' mit den       Sehablonenteilen    7, 7' ein- und ausgespannt  werden können. Durch die Rolle 10 werden  die Werkstücke mit den     Schablonenteilen    ge  führt.  



  Nach     Ingangsetzung    der Maschine werden  die Formwalzen 2 durch ein     Ilbersetzungs-          getriebe    12, das auch die Welle 9 mit der  Leitrolle 8 antreibt, in Umdrehung gesetzt.  Es bleibt sich dabei gleichgültig, ob alle  Formwalzen oder nur die zum Einsatz kom  mende in Umlauf gebracht werden.

   Die für  den ersten Arbeitsgang zum Einsatz kom  mende Formwalze wird mit der Scheibe 1  durch eine in Pfeilrichtung 13 wirkende,  bereits an     Sickenmaschinen        bekannten        Ver-          stellvorrichtung    14 auf die Arbeitsbleche     ss,     6' gedrückt und diese mit den Schablonen  teilen 7, 7' entlang der Formwalze ? verscho  ben, wodurch die zu bearbeitenden Bleche  entsprechend verformt werden.

   Sobald der  Durchlauf beendigt ist, wird die Scheibe 1  auf die zweite Arbeitsstufe eingestellt und  durch Umschaltung der Maschine auf     Rizck-          wärtsgang    die Bleche zur weiteren Bearbei  tung zurückgeführt und so fort, bis die ge  wünschte Verformung erzielt ist. In der be-         schriebenen    Vorrichtung sind zwei     Bleche    6,  6'     vorhanden,    an denen in einem Arbeitsgang  spiegelgleiche Profilränder hergestellt -wer  den. Dies ist natürlich nur für zwei Bleche  mit einseitigem Profil möglich.     Bleche,    die  ein symmetrisches Profil besitzen, können nur  einzeln hergestellt werden.

   Auf der kreisför  migen Scheibe können weit mehr Walzen an  geordnet werden, als dies bei.     achsialer    Neben  einanderanordnung der Fall ist.



  Device for producing profile edges on metal sheets. The invention relates to a device for the step-by-step production of profile edges on metal sheets, in particular those with curved shapes, by means of forming rollers that run over two-part templates that hold the sheet between .sich holding them while they are guided over the forming rollers against arranged backup rollers. In the known devices of this type, the forming rollers for the individual work stages are arranged coaxially on a common shaft.



  According to the invention, however, the forming rollers for the individual work stages are superimposed on the edge of a circular disc. This has the advantage that the workpiece can be produced much faster than before, since the disc carrying the individual rollers can be rotated quickly and the workpiece cannot be reclamped for the following work step. The device can also have smaller dimensions in depth, since the arrangement of the forming rollers on the circular disc takes up much less space than the previous design. By eliminating the relatively long shaft carrying the rollers, the risk of accidents is also reduced.



  In the drawing, an execution example of the subject invention is provided, namely Fig. 1 shows a disc 1 on which the forming rollers 2 are rotatably mounted on the edge on pin-like projections ä. The shape of the rollers 2 is, based on the cross-section, selected so that each individual roller is a progressive work stage that is more and more equal to the desired finished shape of the sheet metal part to be processed.



  Fig. 2 shows the entire device schematically partially in section. The disk 1 is arranged to be rotatable about the axis 4 and can be held in certain positions with a locking device 5 so that the roller corresponding to the required operation is always used. The sheets to be processed 6, 6 'are clamped between tween two template parts 7 and 7', which can be made of wood or a similar material, and attached to the guide roller 8. This is rigidly attached to the shaft 9, while the roller 10 is rotatably mounted on the stationary axle 11. is.

    The roller 10 is axially displaceable ver in the direction of the arrow, so that the sheets 6, 6 'with the viewing template parts 7, 7' can be clamped and unclamped. Through the role 10, the workpieces with the template parts are ge leads.



  After the machine is started, the forming rollers 2 are set in rotation by a transmission gear 12 which also drives the shaft 9 with the guide roller 8. It does not matter whether all of the forming rollers or only those that are used are put into circulation.

   The form roll used for the first step is pressed with the disk 1 by an adjusting device 14 already known on beading machines and acting in the direction of arrow 13 onto the work sheets 6 ′ and share them with the templates 7, 7 ′ along the Forming roller? ben shifted, whereby the sheets to be processed are deformed accordingly.

   As soon as the run is finished, the disc 1 is set to the second working stage and by switching the machine to reverse gear, the sheets are returned for further processing and so on until the desired deformation is achieved. In the device described, there are two metal sheets 6, 6 ', on which mirror-identical profile edges are produced in one operation. Of course, this is only possible for two sheets with a profile on one side. Sheets that have a symmetrical profile can only be produced individually.

   Far more rollers can be arranged on thekreisför shaped disk than with. axial side by side arrangement is the case.
