Description

Die Erfindung betrifft eine Vorrichtung zum Richten von Metallprofilen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for straightening metal profiles according to the preamble of patent claim 1.

Vorrichtungen dieser Art sind beispielsweise aus dem Dokument DE19606875C1 bekannt. Sie dienen in metallverarbeitenden Betrieben dazu, verkrümmte Profilstangen gerade zu richten. Ihre Wirkungsweise beruht auf dem Prinzip, das zu richtende Profil nacheinander in entgegengesetzten Richtung rechtwinklig zur Durchlaufrichtung durch die Vorrichtung plastisch zu verformen, so dass das Profil schliesslich gerade ist. Eine Schwierigkeit besteht dabei darin, die Einstellung der Position der einzelnen Rollen in Bezug auf das zu richtende Profil an unterschiedlich dicke Profile anzupassen.Devices of this kind are for example from the document DE19606875C1 known. They are used in metal processing companies to straighten crooked profile bars. Its mode of operation is based on the principle of plastically deforming the profile to be straightened one after the other in the opposite direction at right angles to the direction of passage through the device, so that the profile is finally straight. One difficulty here is adjusting the position of the individual rollers in relation to the profile to be straightened to profiles of different thicknesses.

Unter dem Begriff Dicke soll im vorliegenden Zusammenhang die Dimension des zu richtenden Profils senkrecht zu dessen Durchlaufrichtung durch die Vorrichtung verstanden werden.In the present context, the term thickness should be understood to mean the dimension of the profile to be straightened perpendicular to its direction of passage through the device.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, Eine Vorrichtung zum Richten von Metallprofilen vorzuschlagen, bei der die Umstellung von einem Profil auf ein anderes einfach ausführbar ist, so dass sie auch durch ungeschultes Personal bewältigt werden kann.Proceeding from this state of the art, the invention is based on the object of proposing a device for straightening metal profiles, in which the changeover from one profile to another can be carried out easily, so that it can also be managed by untrained personnel.

Diese Aufgabe wird erfindungsgemäss durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst.According to the invention, this object is achieved by the features specified in the characterizing part of patent claim 1 .

Durch das Einstellgetriebe ist es möglich, mit einem einzigen Bedienelement, eine Transportrolle und alle Richtrollen gemeinsam an die Dicke des zu richtenden Profils anzupassen.The setting gear makes it possible to use a single control element to adjust a transport roller and all straightening rollers together to the thickness of the profile to be straightened.

Figur 1 zeigt eine perspektivische Ansicht eines Ausführungsbeispiels der erfindungsgemässen Vorrichtung 1. Eine durch ein Gehäuse 73 abgedeckte Richteinheit 2 ist auf einem fahrbaren Untergestell 3 montiert. Die Bezugszahl 4 bezeichnet die Durchlaufrichtung der zu richtenden Profile, in Figur 1 von links nach rechts. Die Profile werden auf eine Führungseinheit 5 aufgelegt und gelangen nach dem Richtvorgang auf eine Ablageschiene 6. Unterhalb der Richteinheit 2 ist im Untergestell 3 eine Steuereinheit 7 angeordnet. Ein Einstellknopf 8 dient zur Anpassung der Vorrichtung an die Dicke des zu richtenden Profils, wobei der eingestellte Wert an einer Anzeigeeinheit 9 ablesbar ist. Die Funktion eines Korrekturknopfs 30, der in Durchlaufrichtung 4 entfernt vom Einstellknopf 8 angeordnet ist, wird weiter unten näher erläutert. figure 1 shows a perspective view of an embodiment of the device 1 according to the invention. The reference number 4 indicates the direction of passage of the profiles to be straightened, in figure 1 left to right. The profiles are placed on a guide unit 5 and, after the straightening process, reach a storage rail 6 . A control unit 7 is arranged in the subframe 3 below the straightening unit 2 . An adjustment button 8 is used to adapt the device to the thickness of the profile to be straightened, the value set being readable on a display unit 9 . The function of a correction button 30, which is arranged at a distance from the setting button 8 in the direction of passage 4, is explained in more detail below.

Figur 2 zeigt eine perspektivische Ansicht der Vorrichtung von Figur 1 aus einem anderen Blickwinkel. Die Durchlaufrichtung 4 führt hier von rechts nach links. Zusätzlich zu den anhand der Figur 1 erläuterten Komponenten zeigt Figur 2 einen Antriebsmotor 11 und ein Getriebe 12, vorzugsweise ein Schneckengetriebe. figure 2 shows a perspective view of the device of FIG figure 1 from a different angle. The throughput direction 4 leads here from right to left. In addition to the based on the figure 1 explained components shows figure 2 a drive motor 11 and a gear 12, preferably a worm gear.

Figur 3 zeigt perspektivisch die Richteinheit 2 aus einem ähnlichen Blickwinkel wie Figur 1, wobei das Gehäuse 73 und die dem Betrachter zugewandte Seitenwand 13 (siehe Figur 4) der Richteinheit 2 weggelassen sind. Der Durchlaufrichtung 4 folgend wird das zu richtende Profil zuerst ein Transportrollenpaar 15, 16 passieren, wobei nur die untere Transportrolle 15 angetrieben wird, wie anhand der Figur 4 noch ersichtlich sein wird. Während die untere Transportrolle 15 fest, das heisst unverschiebbar gelagert ist, ist die obere Transportrolle 16 in einem vertikal verschiebbaren Lagerschlitten 17 angeordnet, dessen vertikale Position mittels des Einstellknopfs 8 der Dicke des zu richtenden Profils anpassbar ist, wobei der eingestellte Wert an der Anzeigeeinheit 9 ablesbar ist. Weiter in Durchlaufrichtung 4 folgen dem Transportrollenpaar 15, 16 vier Stützrollen 18, 19, 20 und 21, die alle fest gelagert und angetrieben sind, wie dies im Zusammenhang mit Figur 4 noch deutlich wird. Oberhalb der Stützrollen 18 bis 21 sind drei Richtrollen 22, 25 und 28 in Durchlaufrichtung 4 in Bezug auf die Stützrollen 18 bis 21 versetzt angeordnet. Jede Richtrolle ist in einem vertikal verschiebbaren Lagerschlitten angeordnet, also Richtrolle 22 im Lagerschlitten 23, Richtrolle 25 im Lagerschlitten 26 und Richtrolle 28 im Lagerschlitten 29. Zu jedem Lagerschlitten 23, 26 und 29 gehört ein entsprechender Justierknopf 24, 27 bzw. 30. figure 3 shows the straightening unit 2 in perspective from a similar angle as FIG figure 1 , wherein the housing 73 and the side wall 13 facing the viewer (see figure 4 ) of the straightening unit 2 are omitted. The passage direction 4 following the profile to be straightened will first pass a pair of transport rollers 15, 16, with only the lower Transport roller 15 is driven, as shown in the figure 4 will still be evident. While the lower transport roller 15 is mounted in a fixed, i.e. non-displaceable manner, the upper transport roller 16 is arranged in a vertically displaceable bearing carriage 17, the vertical position of which can be adjusted to the thickness of the profile to be straightened using the adjustment knob 8, the value set being shown on the display unit 9 is readable. Further in the direction of passage 4, the pair of transport rollers 15, 16 are followed by four supporting rollers 18, 19, 20 and 21, all of which are fixed and driven, as is the case in connection with FIG figure 4 still becomes clear. Above the support rollers 18 to 21 are three straightening rollers 22, 25 and 28 in the direction of passage 4 with respect to the support rollers 18 to 21 offset. Each straightening roller is arranged in a vertically displaceable bearing carriage, i.e. straightening roller 22 in bearing carriage 23, straightening roller 25 in bearing carriage 26 and straightening roller 28 in bearing carriage 29. Each bearing carriage 23, 26 and 29 has a corresponding adjustment knob 24, 27 or 30.

Es fällt auf, dass der Justierknopf 30 etwa in der gleichen Höhe angeordnet ist wie der Einstellknopf 8, während die beiden anderen Justierknöpfe 24 und 27 etwas tiefer positioniert sind. Dies hat zur Folge, dass bei montiertem Gehäuse 73 nur der Einstellknopf 8 und der Justierknopf 30 oben aus dem Gehäuse 73 hinausragen und damit für eine Person zugänglich sind, welche die Vorrichtung bedient. Dies beruht auf der Erkenntnis, dass die Richtrollen 22 und 25 nur einmal bei der Montage der Vorrichtung in ihrer relativen vertikalen Lage justiert werden müssen. Später im Betrieb werden alle Richtrollen 22, 25 und 28 zwecks Anpassung an die Dicke des zu richtenden Profils gleichzeitig um den gleichen Betrag mittels des Einstellknopfs 8 verschoben. Es wurde gefunden, dass es genügt, mittels des Justierknopfs 30 Korrekturen vorzunehmen und das zu richtende Profil noch einmal durch die Vorrichtung zu lassen, wenn es nach dem ersten Durchlauf nicht die gewünschte Geradheit aufweist.It is noticeable that the adjustment knob 30 is arranged at approximately the same height as the adjustment knob 8, while the other two adjustment knobs 24 and 27 are positioned somewhat lower. As a result, when the housing 73 is mounted, only the setting button 8 and the adjustment button 30 protrude from the top of the housing 73 and are therefore accessible to a person operating the device. This is based on the knowledge that the straightening rollers 22 and 25 only have to be adjusted once in their relative vertical position during assembly of the device. Later in operation, all the straightening rollers 22, 25 and 28 are simultaneously shifted by the same amount by means of the adjustment knob 8 in order to adapt to the thickness of the profile to be straightened. It has been found that it is sufficient to make corrections using the adjusting knob 30 and to let the profile to be straightened through the device again if it does not have the desired straightness after the first pass.

Figur 4 zeigt perspektivisch die Richteinheit 2 aus einem ähnlichen Blickwinkel wie Figur 2, jedoch ohne Gehäuse. Die in der Figur oberen Komponenten bilden zusammen ein Einstellgetriebe 31. Dazu gehören ein Riemenrad 32 auf der Achse des Einstellknopfs 8, ein Riemenradpaar 33 auf der Achse des Justierknopfs 24, ein Riemenradpaar 34 auf der Achse des Justierknopfs 27 und ein Riemenrad 35 auf der Achse des Justierknopfs 30. Ein erster Zahnriemen 36 verbindet das Riemenrad 32 mit dem Riemenradpaar 33, ein zweiter Zahnriemen 37 verbindet das Riemenradpaar 33 mit dem Riemenradpaar 34 und ein dritter Zahnriemen 38 verbindet das Riemenradpaar 34 mit dem Riemenrad 35. Jeder der drei Zahnriemen 36, 37 und 38 ist durch jeweils eine Spannrolle 39, 40 und 41 (Figur 3) gespannt. Das Einstellgetriebe 31 bewirkt, dass durch eine Drehung am Einstellknopf 8 zwecks Anpassung an die Dicke des zu richtenden Profils sowohl die obere Transportrolle 16 als auch die drei Richtrollen 22, 25 und 28 jeweils um den gleichen Betrag in die gleiche Richtung verstellt werden. figure 4 shows the straightening unit 2 in perspective from a similar angle as FIG figure 2 , but without housing. The upper components in the figure together form an adjustment gear 31. These include a belt wheel 32 on the axis of the adjustment knob 8, a pair of belt wheels 33 on the axis of the adjustment knob 24, a pair of belt wheels 34 on the axis of the adjustment knob 27 and a belt wheel 35 on the axis of the adjustment knob 30. A first toothed belt 36 connects the belt wheel 32 with the belt wheel pair 33, a second toothed belt 37 connects the belt wheel pair 33 with the belt wheel pair 34 and a third toothed belt 38 connects the belt wheel pair 34 with the belt wheel 35. Each of the three toothed belts 36, 37 and 38 is connected by a respective idler pulley 39, 40 and 41 ( figure 3 ) curious; excited. The adjustment gear 31 causes the upper transport roller 16 and the three straightening rollers 22, 25 and 28 to be adjusted by the same amount in the same direction by turning the adjusting knob 8 to adapt to the thickness of the profile to be straightened.

Figur 4 zeigt ausserdem, wie die untere Transportrolle 15 und die vier Stützrollen 18, 19, 20 und 21 angetrieben werden. Ausgehend von einer mit einem Zahnrad bestückten und mit dem Getriebe 12 (Figur 2) verbundenen Antriebswelle 50 wird das Antriebsdrehmoment gleichzeitig auf die ebenfalls mit einem Zahnrad ausgerüstete Welle 45 der Stützrolle 20 und die mit einem Zahnrad ausgerüstete Welle 46 der Stützrolle 21 übertragen und treibt diese beiden Wellen in der gleichen Drehrichtung an. Über Zwischenzahnräder 49, 48 und 47 werden auch die Welle 44 der Stützrolle 19, die Welle 43 der Stützrolle 18 und die Welle 42 der Transportrolle 15 angetrieben. figure 4 also shows how the lower transport roller 15 and the four support rollers 18, 19, 20 and 21 are driven. Based on a gear equipped with a gear and with the gear 12 ( figure 2 ) connected drive shaft 50, the drive torque is simultaneously transmitted to the geared shaft 45 of the support roller 20 and the geared shaft 46 of the support roller 21 and drives these two shafts in the same direction of rotation. The shaft 44 of the support roller 19, the shaft 43 of the support roller 18 and the shaft 42 of the transport roller 15 are also driven via intermediate gear wheels 49, 48 and 47.

Figur 5 zeigt einen Längsschnitt durch das Einstellgetriebe 31 von Figur 4. Die dazu gehörenden Elemente sind auf einer Grundplatte 51 aufgebaut. Der Einstellknopf 8 ist mit einer Spindel 52 verbunden, die mittels einer Gewindeverbindung 53 mit der Grundplatte 51 gegenüber dieser in der Figur vertikal verschiebbar ist und mit ihrer Stirnfläche 54 auf den Lagerschlitten 17 einwirkt. An der Spindel 52 ist das im Zusammenhang mit Figur 4 erwähnte Riemenrad 32 drehfest verbunden. Die anderen im Zusammenhang mit Figur 4 erwähnten Riemenräder beziehungsweise Riemenradpaare sind jeweils mit einer Hohlspindel 55, 59, 63 verbunden, die ihrerseits mittels jeweils einer Gewindeverbindung 56, 60, 64 mit der Grundplatte 51 gegenüber dieser in der Figur vertikal verschiebbar sind. In jeder der drei Hohlspindeln ist jeweils einer der Justierknöpfe 24, 27, 30 über eine Gewindeverbindung 57, 61, 65 gekoppelt. Die Stirnflächen 58, 62 und 66 wirken jeweils auf den zugehörigen Lagerschlitten 23, 26, 29 ein. figure 5 shows a longitudinal section through the setting gear 31 of figure 4 . The associated elements are built on a base plate 51 . The adjusting knob 8 is connected to a spindle 52 which can be displaced vertically with respect to the base plate 51 in the figure by means of a threaded connection 53 and acts with its end face 54 on the bearing carriage 17 . On the spindle 52 is related to figure 4 mentioned pulley 32 rotatably connected. The others related to figure 4 Mentioned belt wheels or belt wheel pairs are each connected to a hollow spindle 55, 59, 63, which in turn can be displaced vertically with respect to the base plate 51 in the figure by means of a respective threaded connection 56, 60, 64. One of the adjusting knobs 24, 27, 30 is coupled via a threaded connection 57, 61, 65 in each of the three hollow spindles. The end faces 58, 62 and 66 each act on the associated bearing carriage 23, 26, 29.

Die Funktion des Einstellgetriebes 31 ist derart, dass durch eine Drehung am Einstellknopf 8 der Abstand der Transportrollen 15, 16 entsprechend der Dicke des zu richtenden Profils eingestellt wird. Durch einen Geber 10 wird der Wert an die Anzeigeeinheit 9 übermittelt, wo er abgelesen werden kann, vorzugsweise in Millimeter. Die Drehung des Einstellknopfs 8 wird durch die Zahnriemen 36, 37, 38 auf die Hohlspindeln 55, 59, 63 übertragen, wodurch sich diese mittels der entsprechenden Gewindeverbindungen 56, 60, 64 um den gleichen Betrag in die gleiche Richtung verschieben und dadurch über die Stirnflächen der Justierknöpfe 24, 27, 30 und die Lagerschlitten 23, 26, 29 die Richtrollen 22, 25, 28 entsprechend vertikal positionieren. Die Position der Justierknöpfe bezüglich der zugehörigen Hohlspindeln bleibt bei der Drehung der Hohlspindeln durch Selbsthemmung erhalten. Damit diese Selbsthemmung gewährleistet ist, hat jede Hohlspindel oben einen drehfest mit ihr verbundenen, einstellbaren Spannring 67, 68, 69.The function of the setting gear 31 is such that by turning the setting knob 8, the distance between the transport rollers 15, 16 is set according to the thickness of the profile to be straightened. The value is transmitted by a transmitter 10 to the display unit 9, where it can be read, preferably in millimeters. The rotation of the adjusting knob 8 is transmitted through the toothed belts 36, 37, 38 to the hollow spindles 55, 59, 63, as a result of which these are displaced by the same amount in the same direction by means of the corresponding threaded connections 56, 60, 64 and thereby over the end faces of the adjustment knobs 24, 27, 30 and the Bearing slides 23, 26, 29 position the straightening rollers 22, 25, 28 vertically accordingly. The position of the adjusting knobs in relation to the associated hollow spindles is retained by self-locking when the hollow spindles rotate. In order to ensure this self-locking, each hollow spindle has an adjustable clamping ring 67, 68, 69 connected to it in a rotationally fixed manner.

Anlässlich der Montage der Vorrichtung 1 werden die Justierknöpfe 24, 27, 30 derart eingestellt, dass ein verbogenes Profil mittlerer Dicke nach dem Durchgang durch die Vorrichtung gerade ist. Diese Werkseinstellungen werden dadurch gesichert, dass nach der Montage des Gehäuses nur noch der Einstellknopf 8 und der Justierknopf 30 oben aus dem Gehäuse herausragen. Je nach Dicke des zu richtenden Profils müssen dann nur noch kleinere Korrekturen am Justierknopf 30 vorgenommen werden, der zu diesem Zweck mit einer nicht zeichnerisch dargestellten Skala ausgestattet ist.When the device 1 is assembled, the adjustment knobs 24, 27, 30 are adjusted in such a way that a bent profile of average thickness is straight after passing through the device. These factory settings are secured in that, after the housing has been assembled, only the setting button 8 and the adjusting button 30 protrude from the top of the housing. Depending on the thickness of the profile to be straightened, only minor corrections then have to be made on the adjusting knob 30, which is equipped with a scale not shown in the drawing for this purpose.

Figur 6 zeigt einen Querschnitt durch das Einstellgetriebe 31 entlang der Linie VI - VI in Figur 5. Man sieht, wie der verlängerte Justierknopf 30 mittels der Gewindeverbindung 65 mit der Hohlspindel 63 verbunden ist, welche ihrerseits über die Gewindeverbindung 64 mit der Grundplatte 51 zusammenwirkt. Unterhalb der Grundplatte 51 ist zwischen den Seitenwänden 13 und 14 der die Richtrolle 28 tragende Lagerschlitten 29 vertikal verschiebbar angeordnet und durch in den Seitenwänden 13, 14 abgestützte Federn 70 nach oben vorgespannt. Die Stützrolle 21 ist gegenüber der Schnittebene versetzt unterhalb der Richtrolle 28 angeordnet. Die Stützrollen und Richtrollen, wie auch die Transportrollen können mit Nuten 71, 72 ausgestattet sein, damit die Vorrichtung 1 auch zum Richten von Rundprofilen verwendet werden kann.

It can be seen how the extended adjusting knob 30 is connected to the hollow spindle 63 by means of the threaded connection 65 , which in turn interacts with the base plate 51 via the threaded connection 64 . Below the base plate 51, between the side walls 13 and 14, the bearing carriage 29 carrying the straightening roller 28 is arranged so that it can be displaced vertically and is biased upwards by springs 70 supported in the side walls 13, 14. The support roller 21 is offset below the straightening roller 28 with respect to the cutting plane. The support rollers and straightening rollers, as well as the transport rollers, can be equipped with grooves 71, 72 so that the device 1 can also be used for straightening round profiles. <b>Reference List</b> 1 contraption 31 adjustment gear 61 threaded connection 2 straightening unit 32 pulley 62 face 3 base 33 pulley pair 63 hollow spindle 4 flow direction 34 pulley pair 64 threaded connection 5 Guide unit 35 pulley 65 threaded connection 6 storage rail 36 timing belt 66 face 7 control unit 37 timing belt 67 clamping ring 8th adjustment knob 38 timing belt 68 clamping ring 9 display unit 39 idler pulley 69 clamping ring 10 giver 40 idler pulley 70 feathers 11 drive motor 41 idler pulley 71 groove 12 transmission 42 wave of 15 72 groove 13 Side wall 43 wave of 18 73 Housing 14 Side wall 44 wave of 19 15 transport roller 45 wave of 20 16 transport roller 46 wave of 21 17 storage slide 47 intermediate gear 18 support roller 48 intermediate gear 19 support roller 49 intermediate gear 20 support roller 50 drive shaft 21 support roller 51 base plate 22 first straightening roll 52 spindle 23 storage slide 53 threaded connection 24 adjustment knob 54 face 25 second straightening roll 55 hollow spindle 26 storage slide 56 threaded connection 27 adjustment knob 57 threaded connection 28 third straightening roll 58 face 29 storage slide 59 hollow spindle 30 adjustment knob 60 threaded connection
