Definitions
- the invention relates to a device for straightening metal profiles according to the preamble of patent claim 1.
- 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.
- thickness should be understood to mean the dimension of the profile to be straightened perpendicular to its direction of passage through the device.
- 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.
- 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.
- 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.
- 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.
- figure 2 a drive motor 11 and a gear 12, preferably a worm gear.
- 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.

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.
- 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.
- 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.
- 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.
- 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
- 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.
- figure 4 also shows how the lower transport roller 15 and the four support rollers 18, 19, 20 and 21 are driven.
- 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.
- 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.
- 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.
- each hollow spindle has an adjustable clamping ring 67, 68, 69 connected to it in a rotationally fixed manner.
- 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.
- 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.
- figure 6 shows a cross section through the adjustment gear 31 along the line VI - VI in figure 5 . 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.

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
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
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
