Abstract
Description
In Stahlstranggießanlagen werden die am laufenden Band gegossenen Stränge durch Sauerstoff-Brennschneidmaschinen in Stranggußstücke (1) unterteilt. Beim Brennschneiden entstehen an den Unterkanten der Trennflächen Brennbärte (2) aus Eisenoxiden, die nach und nach in einen Verbindungssteg aus reinem Stahl übergehen.In continuous steel casting plants, the strands cast on the conveyor belt are passed through Oxygen flame cutting machines divided into continuous castings (1). When flame cutting Firebeards (2) made of iron oxides are formed on the lower edges of the separating surfaces and then go into a connecting bar made of pure steel.
Diese Brennbärte (2) stellen bei der Weiterverarbeitung qualitätsmindernde und kostenverursachende Störquellen dar. Daher müssen sie möglichst früh im Fabrikationsablauf durch gasetechnische und mechanische Maßnahmen entfernt werden.These beards (2) represent quality-reducing and further processing cost-causing sources of interference. Therefore, they must be Manufacturing process can be removed by gas engineering and mechanical measures.
Vorzugsweise entfernt man diese Brennbärte (2) mechanisch, wozu in der EPA-0 671 230 und EP-A-0 724 923 vorteilhafte Vorschläge gemacht werden.These beards (2) are preferably removed mechanically, for which purpose EPA-0 671 230 and EP-A-0 724 923 advantageous proposals.
Zur Erklärung der hier vorgestellten Erfindung wird auf das oben aufgeführte Prinzip nach der EPA 0 671 230 verwiesen, bei dem in einer Lücke zwischen zwei Rollen (3) direkt nach dem Brennschneidende entweder mitlaufend und überholend der vordere, und stehend oder gegenlaufend der hintere Brennbart (2) am fortlaufend bewegten Stranggußstück (1) entfernt wird und das sicher, leise und wirkungsvoll bei geringstem Aufwand. Dazu wird nach jedem Entbartungsvorgang der Kolbenkörper (7) zum Abwerfen von abgefallenen Brennbärten (2) zu einer Rinne (4) und zum Abstandhalten von der Unterfläche des Stranggußstückes (1) um ca. 60° bis 90° gedreht.To explain the invention presented here is based on the principle listed above referred to EPA 0 671 230, in which in a gap between two rollers (3) directly after the flame cutting end, either running and overtaking the front, and standing or in the opposite direction the rear burning bit (2) on the continuously moving continuous casting (1) is removed safely, quietly and effectively with minimal effort. This will after each deburring process, the piston body (7) for throwing off fallen ones Firebeards (2) to a gutter (4) and to keep away from the lower surface of the Continuous casting (1) rotated by about 60 ° to 90 °.
Dazu besteht ein solcher Entbarter, wie in den Bildern 1 bis 2 dargestellt, aus einem Entbarterwagen (5), der aus einem Träger (12) und zwei Wangen (13) zusammengeschweißt ist. Außen an den Wangen (13) sind 3 oder 4 glatte Laufräder (15) ohne Führungsflansche in Laufradlagern (16) angebracht, die auf einer Unterschiene (22) laufen und von einer Oberschiene (23) am Hochgehen bei einem Kippvorgang gehindert werden. Ebenfalls außen an den Wangen (13) sitzen in Ritzellagern (18) zwei Ritzel (17), die mit Zahnstangen (25), die auch als Führungsschienen (25) dienen, kämmen. Die Ritzel (17) sind von zwei Antrieben innerhalb der Wangen (13), die aus Getriebe (19) mit die Wangen (13) durchdringenden Wellen und Elektromotoren (20) bestehen, angetrieben und haben geringste Zähnezahlen zur Erzeugung größter Momente. Ebenfalls an den Außenseiten der Wangen (13) befinden sich Führungsleisten (14) aus gleitgünstigem Material, die an den glattgearbeiteten Seiten der Zahnstangen (25) auch als Führungsschiene (25) dienend, den Entbarterwagen (5) führend entlanggleiten. For this purpose, such a degrader consists of one, as shown in Figures 1 to 2 Entbarterwagen (5), which is welded together from a carrier (12) and two cheeks (13) is. On the outside of the cheeks (13) there are 3 or 4 smooth impellers (15) Guide flanges mounted in impeller bearings (16) that run on a lower rail (22) and are prevented by a top rail (23) from going up during a tipping process. Also on the outside of the cheeks (13), two pinions (17) are seated in pinion bearings (18) Comb tooth racks (25), which also serve as guide rails (25). The pinions (17) are of two drives within the cheeks (13), consisting of gear (19) with the cheeks (13) penetrating shafts and electric motors (20) exist, driven and have lowest number of teeth to generate greatest moments. Also to the Outside of the cheeks (13) there are guide strips (14) made of low-friction Material on the smooth sides of the racks (25) also as a guide rail (25) serving, sliding along the Entbarterwagen (5) leading.
Auf dem Träger (12) des Entbarterwagens (5) befinden sich zwei Drehlager (11), in denen sich der Kolbenkörper (7) mit seinen eindrückbaren Scherkolben (6) an seinen für das Drehlager (11) gearbeiteten Deckeln (8) drehen kann. Auf den Stirnflächen der Deckel (8) sind normalerweise waagerecht stehende Gleitstücke (9) angebracht, die auf den Gleitschienen (24) an der Oberkante der Oberschiene (23) entlanggleiten und die Scherkolben (6) im Kolbenkörper (7) in senkrechter Lage halten. Wird ein kleiner Winkel zwischen Unterfläche des Stranggußstückes (1) und Scherkolben (6) vorgesehen, so ist dieser leicht durch einen Spalt zwischen den Gleitstücken (9) und den Gleitschienen (24) zum selbsttätigen Einstellen zu erzeugen. An den Endstellungen der Schienen sind die Gleitschienen (24) für ein Drehen der Gleitstücke (9) mit Kolbenkörper (7) zurückgeschnitten und ein Drehpuffer (26) mit angeschrägtem Anlauf zwingt den durch den Entbarterwagen (5) gerade noch verfahrenden Kolbenkörper (7) an den Drehknöpfen (10), sich um eine durch die Konstruktion vorgegebene Gradzahl zu drehen. Beim Verfahren aus der Endstellung zwingt die Gleitschiene (24) über die Gleitstücke (9) die Kolbenkörper (7), wieder gerade oder nahezu gerade zu werden.There are two pivot bearings (11) on the carrier (12) of the Entbarterwagens (5), in which the piston body (7) with its push-in shear piston (6) on its for Rotary bearing (11) machined covers (8) can rotate. On the end faces of the covers (8) are usually horizontal sliders (9) attached to the Slide the slide rails (24) along the upper edge of the upper rail (23) and the Hold the shear piston (6) in the piston body (7) in a vertical position. Becomes a small angle is provided between the lower surface of the continuous casting (1) and the shear piston (6) this easily through a gap between the sliders (9) and the slide rails (24) to generate for automatic adjustment. At the end positions of the rails are the Cut the slide rails (24) back for turning the slide pieces (9) with the piston body (7) and a rotary buffer (26) with a chamfered start forces it through the bearer car (5) just moving piston body (7) on the knobs (10), one the number of degrees specified by the construction. When moving out of End position forces the slide rail (24) via the slide pieces (9), the piston body (7), to become straight again or almost straight again.
Ein Arbeitszyklus für 2 Entbartungen mit diesem Entbarter geht wie folgt vor sich:A working cycle for 2 debonings with this debacher is as follows:
Mittels eines Stellungsgebers z. B. Lichtschranke wird der sich unter dem ankommenden Stranggußstück (1) befindliche Entbarter auf Mitlauf geschaltet, und der Antrieb verfährt diesen bei gleichzeitigem Hochdrehen des Kolbenkörpers (7) und Eindrücken der Scherkolben (6) durch die Unterfläche des Stranggußstückes (1). Danach wird eine höhere Geschwindigkeit eingeschaltet, die Scherkolben (6) überholen entbartend das vordere Ende des Stranggußstückes (1), springen waagerechte Bartreste abschlagend hoch und werden in der anderen Endstellung reinigend und den Weg für das Stranggußstück (1) freimachend abgedreht. Vor dem Überlauf durch das hintere Ende des Stranggußstückes (1) wird entsprechend ausgelöst der Entbarter wieder angefahren, dreht den Kolbenkörper (7) nach oben, drückt mit dem Scherkolben (6) gegen die Unterflächen, kippt in den kleinen Scherwinkel und entbartet stillstehend oder gegenlaufend den Brennbart (2) am hinteren Ende des Stranggußstückes (1). Danach läuft der Entbarter in die Ausgangsstellung zum Abdrehen weiter und erwartet hier das nächste Stranggußstück (1). By means of a position transmitter z. B. Photoelectric sensor will be under the incoming Continuous casting (1) located beards switched to idle, and the drive moves this while turning up the piston body (7) and pressing in Shear piston (6) through the lower surface of the continuous casting (1). After that, a higher one When the speed is switched on, the shear pistons (6) pass the front end of the continuous casting (1), horizontal beard remnants jump off and become in cleaning the other end position and clearing the way for the continuous casting (1) turned off. Before the overflow through the rear end of the continuous casting (1) triggered accordingly, the bearer started again, rotates the piston body (7) above, presses against the lower surfaces with the shear piston (6), tilts into the small one Scherwinkel and debilitating or counteracting the beard (2) on the rear End of the continuous casting (1). Then the bearer runs to the starting position Continue turning and awaiting the next continuous casting (1).
Die zum Entbarten benötigte Energie zum Abscheren oder zum Abschlagen des Brennbartes
(2) ergibt sich beim gegenläufigen Entbarten - Stranggußstück (1) und Entbarterwagen (5)
laufen gegeneinander - als Summe der jeweiligen Bewegungsenergie, wobei das
Stranggußstück (1) durch sein hohes Gewicht auch einen sehr großen Anteil an der
verfügbaren Gesamtenergie hat:
Beim Entbarten am weglaufenden Stranggußstück jedoch verringert sich die verfügbare
Entbartungsenergie auf die vom Entbarterwagen (5) erzeugte. Das Weglaufen des
Stranggußstücks (1) verändert diese durch Verringern der relativen Geschwindigkeit und
dazu kommt die plastische Verformung'des oft noch sehr warmen, breiten Brennbartes (2).
Diese Energieverringerung kann nur durch Erhöhung der Energie des Entbarterwagens (5)
ausgeglichen werden. Zu diesem Zwecke wird der durchschnittliche Fachmann das
Gewicht, d. h. die Masse des Entbarterwagens (5) und seine Geschwindigkeit erhöhen. Hier
jedoch sind die konstruktiven Möglichkeiten aus Platzgründen, Weg- und Bremsweggründen
sowie aus Kostengründen begrenzt.The energy required for deburring to shear off or cut off the mustache (2) results from the opposing deburring - continuous casting (1) and degrading wagon (5) run against each other - as the sum of the respective kinetic energy, the continuous casting (1) also due to its high weight has a very large share of the total energy available:
When debinding on the continuous casting, however, the available deburring energy is reduced to that generated by the debarring wagon (5). The running away of the continuous casting (1) changes this by reducing the relative speed and in addition there is the plastic deformation of the often still very warm, broad mustache (2). This reduction in energy can only be compensated for by increasing the energy of the patient (5). For this purpose, the average person skilled in the art will increase the weight, ie the mass of the barber car (5) and its speed. Here, however, the design options are limited for reasons of space, distance and braking distance as well as cost reasons.
Erfindungsgemäß und wie in Anspruch 1 (Bild 3) vorgeschlagen, ist der Einbau einer Schwungscheibe (27) an einem zweiten Wellenende eines der Antriebsmotoren und dessen Verbindung mittels einer Kupplung (21) mit dem zweiten Wellenende des anderen Elektromotors (20) vorgesehen, wobei beide Elektromotoren (20) wegen des anpassenden Schlupfes als Asynchronmotoren ausgeführt sind. Damit sind erhebliche, leicht über die Motordrehzahl beeinflußbare und platzsparende Energieerhöhungen und entsprechende Abbremsmöglichkeiten gegeben. Zusätzlich sind die Motorluftschrauben in den Motoren gegen solche größerer Masse für zusätzlich große Entbartungsmomente durch Form und vor allem schwereres Material, zum Beispiel Stahl statt Aluminium ausgetauscht.According to the invention and as proposed in claim 1 (Figure 3), the installation is a Flywheel (27) on a second shaft end of one of the drive motors and its Connection by means of a coupling (21) to the second shaft end of the other Electric motor (20) is provided, both electric motors (20) because of the adapting Slips are designed as asynchronous motors. So that are substantial, easy about that Motor speed influenceable and space-saving energy increases and corresponding Braking opportunities given. In addition, the engine propellers are in the engines against such larger mass for additional large deburring moments through form and before all heavier material, for example steel instead of aluminum.
In Anspruch 1 (Bild 1 und 3) wird weiterhin vorgeschlagen, die Antriebsritzel (17) möglichst klein - minimale Zähnezahl bei kleinstem Modul - fertigkeitsmäßig ausgeglichen durch hochfeste Materialien, auszuführen. Dadurch entsteht eine Erhöhung des Vortriebmomentes, da die Übersetzung bei gleichem Motor und Getriebe (19) das Motormoment bestens nutzt. In claim 1 (Figures 1 and 3) it is further proposed that the drive pinion (17) as possible small - minimum number of teeth with the smallest module - balanced in terms of production through high-strength materials. This creates an increase in the driving torque, since the transmission uses the engine torque optimally with the same engine and transmission (19).
In Anspruch 2 wird vorgesehen die Entbartung durch einen Doppelschlag vorzunehmen,
indem der überholende Entbarterwagen (5) dem Brennbart (2) schnell folgt, gegen ihn mit
den Scherkolben (6) schlägt und bei nicht erfolgtem schnellem Weiterlauf anhält, kurz
zurückläuft und im Bereich des verfügbaren Entbartungsweges einen zweiten Anlauf mit
zweitem Entbartungsschlag durchführt. Mit Hilfe von Endschaltern, Lichtschranken,
Zeitrelais und einer Strommessung der Elektromotoren ist eine entsprechende Steuerung
leicht darstellbar.In
In Anspruch 3 ( Bild 4) wird ein neuer Schermeisel (28) beschrieben, der nicht als eine runde Scherkappe, sondern als rechteckiges, den Entbarterkolben überragendes Rechteck mit angeschrägten; austauschbaren, gegen eine Schulter abgestützten Scherschneiden (29) aus kosten- und fertigungstechnisch aufwendigem Spezialmaterial vorgesehen ist. In claim 3 (Figure 4) a new chisel (28) is described, which is not a round Shaving cap, but rather as a rectangular rectangle that protrudes above the bulbous bulb bevelled; exchangeable shear blades (29) supported against a shoulder Costly and manufacturing-technically complex special material is provided.
