Description

förmiger Lenker 36 gelagert. Am anderen Ende steht dieser mittels eines durchgehenden Bolzens 37 mit einem Hebel 38 in gelenkiger Verbindung, der um einen Bolzen 39 an einer am Rahmen 1 befestigten seitlich verstellbaren Lagerung 40 verschwenkbar ist.shaped handlebar 36 mounted. At the other end is this by means of a through bolt 37 with a lever 38 in an articulated connection, which around a bolt 39 is pivotable on a laterally adjustable bearing 40 attached to the frame 1.

Zur Einstellung der Einrichtung, wie sie F i g. 3 zeigt, wurde die Kolbenstange 18 in den Zylinder 17 auf hydraulischem oder pneumatischem Wege zurückgezogen, so daß dadurch die Konsole 13 samt Gleitstück 10 und den an diesem befestigten Teilen 7, 8, 9, 11, 12, 19, 20, 23, 24, 25 und 26 angehoben wurde, wodurch auch der Zylinder 29 verschwenkt worden ist. Das Lagerstück 33 wird nun durch Lösen der Schrauben 32 und Einschrauben derselben in weiter unten befindliche Schraubenbohrungen 31 in einer tieferen Lage fixiert. Der Lenker 36 sowie der Hebel 38 werden dann nach Lösen der Bolzen 34, 37 und 39 gegen einen längeren Lenker 36 π bzw. einen längeren Hebel 38 α und Wiedereinführen der zuletzt genannten drei Bolzen ausgetauscht.To set the device as shown in FIG. 3 shows, the piston rod 18 has been withdrawn into the cylinder 17 by hydraulic or pneumatic means, so that the console 13 together with the slide 10 and the parts 7, 8, 9, 11, 12, 19, 20, 23, 24 attached to it , 25 and 26 has been raised, whereby the cylinder 29 has also been pivoted. The bearing piece 33 is now fixed in a lower position by loosening the screws 32 and screwing them into the screw bores 31 located further down. After loosening the bolts 34, 37 and 39, the handlebar 36 and the lever 38 are exchanged for a longer handlebar 36 π or a longer lever 38 α and the last-mentioned three bolts are reinserted.

Wie aus den waagerechten Pfeilen in F i g. 1 links hervorgeht, laufen die zu verarbeitenden Stäbe 15. 21, 22 von links in die Einrichtung ein. Die Kolben der beiden waagerechten Zylinder 23 sind hierbei vorgeschoben, so daß die beiden Bolzen 24 nach innen vorstehen und die Rundstäbe 21, 22 auf ihnen aufruhen, welche, in Fig. 1 links von diesen Bolzen. geradl'"ig verlaufen. Der Kolben und die Kolbenstange 28 des Zylinders 29 sind hierbei ausgefahren, so daß sich die beiden Hebel 26 und 38 sowie der Lenker 36 in der in Fig. 1 strichpunktiert angedeuteten Lage befinden. Hierbei liegt der Bolzen 34 oberhalb der waagerecht einlaufenden Rundstäbe 21 und 22.As can be seen from the horizontal arrows in FIG. 1 on the left, the bars 15 to be processed run. 21, 22 from the left into the facility. The pistons of the two horizontal cylinders 23 are here advanced so that the two bolts 24 protrude inward and the round bars 21, 22 on them rest which, in Fig. 1 to the left of these bolts. straight. The piston and the piston rod 28 of the cylinder 29 are here extended so that the two levers 26 and 38 and the Handlebars 36 are in the position indicated by dash-dotted lines in FIG. 1. The bolt 34 is located here above the horizontally incoming round bars 21 and 22.

Wird nun der Kolben des Zylinders 29 pneumalisch zurückgezogen, so wird der Bolzen 34 um die Achse des Bolzens 25 nach abwärts verschwenkt und drückt hierbei mit seinen Enden auf die beiden Rundstäbe 21 und 22. so daß diese durchgebogen werden, da sie auch aul den Enden des Bolzens 37 ruhen. 4"If the piston of the cylinder 29 is now pulled back pneumatically, the bolt 34 is Axis of the bolt 25 is pivoted downwards and presses with its ends on the two round rods 21 and 22. so that these are bent, since they also rest at the ends of the bolt 37. 4 "

Nun wird der Rahmen 1 durch den Kolben des betreffenden Zylinders vorgeschoben, also in der Zeichnung nach rechts bewegt.Now the frame 1 is affected by the piston of the Cylinder advanced, i.e. moved to the right in the drawing.

Da die Rundstäbe 21 und 22 die beiden Bolzen 24 über einen Teil des Bolzenumfanges umschließen, also an diesen Bolzen hängen, werden sie beim Vorschieben des Rahmens 1 und aller seiner Aufbauten mitgenommen. Diese Vorschubbewegung geht im Ausmaß des Abstandes zweier in gleicher Höhe liegenden Bogen der im Zick-Zack gebogenen Rundstäbe 21 und 22 vor sich.Since the round bars 21 and 22 enclose the two bolts 24 over part of the circumference of the bolt, So hang on these bolts, they will when the frame 1 and all of its superstructures are advanced taken away. This feed movement is to the extent of the distance between two lying at the same height Arch of the zigzag curved rods 21 and 22 in front of you.

Der Kolben des Zylinders 29 wird samt der Kolbenstange 28 nun wieder ausgeschoben, bis die in F i g. 1 strichpunktiert angedeutete Lage der Hebel 26 und 38 sowie des Lenkers 36 erreicht ist. Die Abschrägungen 35 des Bolzens 34 drücken hierbei die im Zick-Zack gebogenen Stäbe 21 und 22 nach außen, so daß diese die Bewegung des Bolzens 34 nicht behindern.The piston of the cylinder 29, together with the piston rod 28, is now pushed out again until the in F i g. 1, the position of the levers 26 and 38 and the link 36, indicated by dash-dotted lines, is reached. The bevels 35 of the bolt 34 push the rods 21 and 22, which are bent in a zigzag, afterwards outside, so that they do not hinder the movement of the bolt 34.

Nun werden die Bolzen 24 durch die Kolben der Zylinder 23 zurückgezogen, worauf der Rahmen 1 dann ungehindert in seine Ausgangsstellung zurückgeschoben wird. Während dieser Rückbewegung des Rahmens verbleiben die Rundstäbe an Ort undNow the bolts 24 are withdrawn by the pistons of the cylinders 23, whereupon the frame 1 is then pushed back unhindered into its starting position. During this return movement of the frame, the rods remain in place and

Es ist damit die ursprüngliche Stellung der einzelnen Teile der Einrichtung wieder erreicht und kann der nächste Biegevorgang beginnen.The original position of the individual parts of the device is thus achieved again and can begin the next bending process.

Die schrittweise vorgeschobenen, gebogenen und geradlinig verbleibenden Rundstäbe werden dann einer Sduveißvorrichtung zugeführt.The gradually advanced, curved and straight remaining round bars are then fed to a Sduveißvorrichtung.

Während bei der Einstellung gemäß Fig. 1 die Kolbenstange 18 samt Konsole 13 und den an dieser befestigten Teilen ein Stück nach abwärts ausgefahren ist und Gitterträger kleinerer Höhe erzeugt werden, ist bei der Einstellung gemäß Fig. 3 die Kolbenstange eingefahren. Der Ablauf der einzelnen Vorgänge vollzieht sich in gleicher Weise, nur daß dann Gitterträger größerer Höhe hergestellt werden. Die Ventile der Preßluftzylinder, welche die einzelnen Bewegungen bewirken, werden vorteilhaft elektronisch gesteuert.While in the setting according to FIG. 1, the piston rod 18 together with the console 13 and on this attached parts is extended a little downwards and lattice girders of smaller heights are created, is in the setting according to FIG. 3, the piston rod retracted. The sequence of the individual processes takes place in the same way, only that then lattice girders of greater height are made. The valves of the compressed air cylinder, which the individual Cause movements are advantageously electronically controlled.
