Die den Gegenstand der Erfindung bildende Vorrichtung dient dazu, stumpfkantiges Profileisen in einem Zuge scharfkantig zu ziehen. Die Vorrichtung besteht im wesentliehen aus hintereinander angeordneten, in ihrer Gemeinschaft das verlangte scharfkantige Profil umgrenzenden Rollenpaaren, durch, welche der Stab hindurchgezogen wird.The device forming the subject of the invention is used for blunt-edged To pull profile iron sharp-edged in one go. The device consists essentially from those arranged one behind the other, in their community the required sharp-edged Profile delimiting pairs of rollers through which the rod is drawn will.
ίο In der Zeichnung· ist:ίο In the drawing is:
Fig. ι die Vorderansicht einer Vorrichtung zum Ziehen scharfkantigen Flacheisens,Fig. Ι the front view of a device for drawing sharp-edged flat iron,
Fig. 2 ein Längsschnitt durch dieselbe, währendFig. 2 is a longitudinal section through the same, while
!5 Fig1· 3> 4 und 5 die verschiedenen Querschnitte des Flacheisens bei den verschiedenen Stufen der Bearbeitung darstellen.! 5 Fig. 1 · 3> 4 and 5 show the different cross-sections of the flat iron at the different stages of processing.
Zwei ringförmige Rahmen α und b sind hintereinander angeordnet. An jedem derselben ist eine Traverse c bezw. d verstellbar befestigt. Diese Verstellbarkeit wird mit . Hilfe konzentrisch mit den Rahmen verlaufender Nuten e bezw. f am Rahmen selbst und entsprechender Nuten g bezw. Jt an den Köpfen der Traversen bewirkt. Wie aus der Zeichnung ersichtlich, können vermittels dieser Einrichtung die Traversen c bezw. d beliebige diametrale Stellungen einnehmen und in diesen Stellungen durch Schrauben festgehalten werden.Two annular frames α and b are arranged one behind the other. At each of these is a traverse c respectively. d adjustable fastened. This adjustability is with. Help concentrically with the frame extending grooves e respectively. f on the frame itself and corresponding grooves g respectively. Jt causes on the heads of the trusses. As can be seen from the drawing, by means of this device, the traverses c BEZW. d assume any diametrical position and be held in these positions by screws.
In der Längsrichtung der Traverse c verschiebbar sind die profilierten Rollen i i angeordnet, welche mittels der Handschrauben k k gegen den zu ziehenden Stab angepreßt werden können. In der um 900 gegen die Traverse c versetzten Traverse d sind die breiteren, ebenfalls profilierten Rollen / / untergebracht, welche mittels Handschrauben m m verstellt werden können.The profiled rollers ii are arranged to be displaceable in the longitudinal direction of the cross member c and can be pressed against the rod to be drawn by means of the hand screws kk. The wider, also profiled rollers / /, which can be adjusted mm by means of hand screws, are accommodated in the cross member d , offset by 90 ° from the cross member c.
Der Vorgang bei Benutzung dieser Vorrichtung zur Herstellung scharfkantigen Flacheisens ist der folgende:The process of using this device to produce sharp-edged flat iron is the following:
Der Stab mit dem rohen Profil nach Fig. 3 wird zunächst zwischen die Rollen i i eingeführt, worauf letztere durch Anziehen der Handschrauben k k fest gegen die Seitenkanten angedrückt werden. Hierauf wird der Stab weitergeschoben und zwischen die Rollen / I gebracht, wonach letztere ebenfalls angepreßt werden, so daß nunmehr der Zug beginnen kann. Hierbei erhält das Rohprofil (Fig. 3) zwischen den Rollen i i zunächst das Zwischenprofil nach Fig. 4 und schließlich zwischen den Rollen I I das verlangte scharfkantige Profil nach Fig. 5.The rod with the raw profile according to FIG. 3 is first inserted between the rollers ii , whereupon the latter are pressed firmly against the side edges by tightening the hand screws kk. Then the rod is pushed further and brought between the rollers / I , after which the latter are also pressed so that the train can now begin. Here, the raw profile (FIG. 3) between the rollers ii first receives the intermediate profile according to FIG. 4 and finally between the rollers II the required sharp-edged profile according to FIG. 5.
Die Seitenränder der Rollen / / haben den Zweck, bei der Führung des Flacheisens mitzuwirken, um ein übermäßiges Fortdrängen der Kanten durch den Druck auf die Flächen zu verhindern.The side edges of the rollers / / have the purpose of guiding the flat iron contribute to excessive displacement of the edges by the pressure on the surfaces to prevent.
Mit Hilfe einer derartigen Vorrichtung ist es möglich, Profile von einer Stärke scharfkantig zu ziehen, deren Herstellung mittels einer Ziehvorrichtung bisher nicht möglich war, sondern nur durch Fräsen erreicht werden konnte.With the help of such a device it is possible to produce profiles of a thickness with sharp edges to draw, the production of which was previously not possible by means of a drawing device, but only achieved by milling could be.
Je nach dem zu bearbeitenden Profil werden nicht nur zwei, sondern drei oder mehrere Rollenpaare hintereinander geschaltet, wobei die erforderlichen Stellungen der Rollen stets deshalb erzielt werden können, weil die Rollen nicht nur in den Traversen gegen-Depending on the profile to be edited, not just two, but three or several pairs of rollers connected in series, with the required positions of the rollers can always be achieved because the roles are not only in the crossbars against each other.
einander, sondern letztere wiederum quer zur Walzrichtung beliebig eingestellt werden können. Man kann also infolgedessen den Rollen innerhalb der Ebene der Rahmen a b usw. jede beliebige Stellung geben. Soll z. B. ein sechskantiger Stab scharfkantig gezogen werden, so müssen drei Rollenpaare hintereinander geschaltet werden. Das erste Rollenpaar würde mit seinen Achsen senkrecht, seine Traverse also wagerecht liegen. Die Traverse des zweiten Rollenpaares müßte eine Neigung von 60° erhalten, und das dritte Rollenpaar schließlich müßte ebenfalls um 6o°, aber versetzt gegen das vorhergehende, geneigt sein. Es ist selbstverständlich, daß die Rollen innerhalb gewisser Grenzen der Breite der Flächen des Stabes entsprechend ausgebildet sein müssen, während eine Anpassung an die Dicke des Stabes durch eine Verschiebung der Rollen innerhalb der Traversen erreicht wird.each other, but the latter in turn can be set as desired across the rolling direction. As a result, the roles can be given any position within the plane of the frame, etc. Should z. If, for example, a hexagonal rod is drawn with a sharp edge, three pairs of rollers must be switched one behind the other. The axes of the first pair of rollers would be vertical, and its traverse would be horizontal. The traverse of the second pair of rollers would have to be inclined by 60 °, and the third pair of rollers would also have to be inclined by 60 °, but offset from the previous one. It goes without saying that the rollers must be designed accordingly within certain limits of the width of the surfaces of the rod, while an adaptation to the thickness of the rod is achieved by shifting the rollers within the traverses.
