Description
transportable D er - Ge gens ' nandbrennmaschine tand der -Ei-findniig- zum ist eine Zerschnei- leicht' den von Stabeisen und Blech. Bei den. bekannten ortsfesten Brennmaschinen muß-das zu behandelnde Material herangebracht werden, welches bei großen Platten sehr umständlich. ist. Das genaue Ausrichten des Werkstückes auf dem Tisch ist sehr zeitraubend und ein genaues Schneiden fast unmöglich. Außerdem ist ein Einbrennen, in dem Tisch kaum zu vermeiden, welches wiederum einen unsauberen Schnitt zur Folge hat.transportable D it - Ge gens 'nandbrennmaschine the -Ei-findniig- tand for Zerschnei- is a slightly' of the rod iron and tin. Both. known stationary burning machines-the material to be treated must be brought up, which is very cumbersome in the case of large plates. is. The exact alignment of the workpiece on the table is very time-consuming and precise cutting is almost impossible. In addition, burn-in can hardly be avoided in the table, which in turn results in an unclean cut.
Der Zweck der vorliegenden Erfindung ist, diese Nachteile auszuscheiden, indem der Brennapparat selbst leicht an das Material herangebracht wird. Das Ausrichtlineal gewährleistet ein sehr genaues Ausrichten innerhalb einer sehr kurzen Zeit und somit einen Schnitt mit-einer Gen@auigkeit von einigen Zehnteln. Das. Haften der Maschine geschieht mittels Elektromagnet. Selbst bei- kleinsten Werkstücken ist ein genaues. Schneiden möglich, da keine Unterlage benötigt wird, sondern die Werkstücke selbst an der Haftvorrichtung gehalten werden. Die Zeichnung veranschaulicht die Maschine in einem Beispiel. Es zeigt Abb. i die Maschine von: der Seite, Abb. a die Maschine .von vorn.The purpose of the present invention is to eliminate these disadvantages, by bringing the furnace itself easily up to the material. The alignment ruler ensures a very precise alignment within a very short time and thus a cut with an accuracy of a few tenths. That. Sticking of the machine happens by means of an electromagnet. Even with the smallest workpieces is an accurate one. Cutting possible as no underlay is required, but the workpieces themselves be held on the adhesive device. The drawing illustrates the machine in one example. Fig. I shows the machine from: the side, Fig. A the machine .from the beginning.
Auf das vorher angezeichnete Material i wird die Handbrennmaschine so aufgesetzt, daß die Ausrichtschiene 2 den Riß genau deckt. Mittels Elektromagnet 3 wird nach Einschalten des Stromes die Handbrennmasch.ine festgehalten. Darauf wird der in der Schwalbenschwanzführung bewegliche Schlittenq. in die Anfangsstellung gebracht. Die Brenndüse 5 ist in der Höhe durch, den Vertikalschlitten6 verstellbar und wird mittels Handrad 7 in den richtigen Abstand gebracht. Vor der Entzündung des Brenners wird die Aüsriehtschiene hochgeklappt. Der Antrieb geschieht durch den. Motor 8 über das Zahnradpaar 9 auf das stufenlose Getriebe io auf das Schneckengetriebe i i über Reibungskupplung 12 zum Ritzel und zur Zahnstange 13. Hat der Brenner die gewünschte Strecke durchlaufen, wird die Kupplung gelöst. Nach Unterbrechung des Stromes kann die Handbrenumaschine abgehoben werden. Bei kleinen Werkstücken, die besonders schwer zu schneiden sind; wird die Handbrennmaschine auf zwei Stützen gelagert. Die Stücke werden wieder mit dem Ausrichtlineal ausgerichtet und von dem Elektromagneten gehalten.The hand-held machine is placed on the previously marked material i in such a way that the alignment rail 2 exactly covers the crack. After switching on the current, the hand-held burning machine is held in place by means of electromagnet 3. The slide, which is movable in the dovetail guide, is then brought to the starting position. The height of the burner nozzle 5 can be adjusted by means of the vertical slide 6 and is brought into the correct distance by means of the hand wheel 7. Before the burner is ignited, the rail is folded up. The drive is done by the. Motor 8 via gear pair 9 to continuously variable transmission io to worm gear ii via friction clutch 12 to pinion and rack 13. Once the burner has traveled the desired distance, the clutch is released. After the power supply has been interrupted, the handheld brenum machine can be lifted off. For small workpieces that are particularly difficult to cut; the hand-held cutting machine is supported on two supports. The pieces are re-aligned with the alignment ruler and held by the electromagnet.
