Description

Die Erfindung betrifft eine Stauchpresse zur Reduktion der Breite von Walzgut, insbesondere der Brammenbreite in Warmbreitband-Vorstraßen mit beidseitig zur Brammenkante angeordneten Preßwerkzeuge aufnehmenden Werkzeugträgern, welche mit Hilfe mindestens eines Kurbeltriebes in Richtung der Reduktion bewegbar sind, wobei der Kurbeltrieb und ein Vorschubantrieb in einem Kurbelgehäuse angeordnet sind.The invention relates to an upsetting press for reducing the width of rolling stock, in particular the slab width in hot wide strip roughing mills, with tool carriers accommodating pressing tools arranged on both sides of the slab edge, which can be moved in the direction of reduction with the aid of at least one crank drive, the crank drive and a feed drive in a crankcase are arranged.

Bei einer fliegenden Stauchpresse gemäß der deutschen Patentanmeldung P 39 17 398.4 sind zur Reduktion der Breite von Brammen in einer Warmbreitband-Vorstraße zu beiden Seiten der Brammenkante Preßwerkzeuge angeordnet, die von Werkzeugträgern aufgenommen sind. Zur Ausbildung eines Reduktionsantriebes wird jedes Preßwerkzeug mit dem zugehörigen Werkzeugträger mit Hilfe eines von einem Kurbeltrieb betätigten Lenkersystems in Richtung der Breitenreduktion der Bramme bewegt, wobei der Kurbeltrieb in seinem Kurbelgehäuse angeordnet ist. Der Kurbeltrieb besteht aus zwei angetriebenen Exzenterwellen; auf jeder Exzenterwelle ist ein Pleuel gelagert; dessen Pleuelkopf steht mit dem Werkzeugträger zur Übertragung der Stauchkräfte in Verbindung. Am Werkzeugträger greift ein im wesentlichen in Richtung des Brammenvorschubs wirkender Vorschubantrieb an. Durch diese Maßnahmen wird der Bewegungsablauf der Preßwerkzeuge für das reduzierende Pressen und für das Vorschieben der Preßwerkzeuge voneinander getrennt steuerbar. Falls der Vorschubantrieb als Hydraulikzylinder ausgebildet ist, kann die Verfahrbewegung des Hydraulikzylinders besonders vorteilhaft in Form einer Weg-Zeitfunktion so gesteuert werden, daß für jede beliebige Vorschubgröße die Synchronisation der Bewegung des Preßwerkzeugs mit der Bewegung der seitlich zu pressenden Bramme gewährleistet ist. Diese Stauchpresse ermöglicht die kontinuierliche Reduktion der Breite der Bramme auf walztechnisch vorgegebene Werte. Die vorteilhafte Konstruktion der Stauchprese gewährleistet deren hohe Verfügbarkeit, so daß eine hohe Produktivität der Walzstraße, in die die Stauchpresse eingebunden ist, gegeben ist.In a flying upsetting press according to German patent application P 39 17 398.4, pressing tools, which are received by tool carriers, are arranged on both sides of the slab edge in order to reduce the width of slabs in a hot wide strip roughing mill. To form a reduction drive, each pressing tool with the associated tool carrier is moved with the aid of a steering system actuated by a crank mechanism in the direction of reducing the width of the slab, the crank mechanism being arranged in its crankcase. The crank mechanism consists of two driven eccentric shafts; A connecting rod is mounted on each eccentric shaft; its connecting rod head is with the tool carrier for transmission of the upsetting forces in connection. A feed drive acting essentially in the direction of the slab feed acts on the tool carrier. These measures make it possible to control the movement sequence of the pressing tools for the reducing pressing and for advancing the pressing tools separately from one another. If the feed drive is designed as a hydraulic cylinder, the traversing movement of the hydraulic cylinder can be controlled particularly advantageously in the form of a travel-time function so that the synchronization of the movement of the pressing tool with the movement of the slab to be pressed laterally is ensured for any feed size. This upsetting press enables the width of the slab to be continuously reduced to values specified by rolling technology. The advantageous construction of the upsetting press ensures its high availability, so that there is a high productivity of the rolling mill in which the upsetting press is integrated.

Aufgabe der vorliegenden Erfindung ist es, die zuvor beschriebene Stauchpresse weiter zu verbessern, insbesondere deren Wartungszeiten zu verkürzen und den Erhaltungsaufwand zu vermindern und die Produktivität der Walzstraße weiter zu erhöhen.The object of the present invention is to further improve the previously described upsetting press, in particular to shorten its maintenance times and to reduce the maintenance effort and to further increase the productivity of the rolling mill.

Diese Aufgabe wird mit den Maßnahmen des Patentanspruchs 1 gelöst. Die Maßnahmen der Patentansprüche 2 bis 8 dienen der weiteren Ausgestaltung der Erfindung.This object is achieved with the measures of claim 1. The measures of claims 2 to 8 serve to further develop the invention.

Nach Anspruch 1 zeichnet sich die gattungsgemäße Stauchpresse dadurch aus, daß das Kurbelgehäuse mit Kurbeltrieb und Vorschubantrieb sowie mit dem Werkzeugträger zu einer Baueinheit zusammengefaßt sind, und daß diese Baueinheit durch ein Ständerfenster des liegenden Pressengerüsts seitlich und etwa parallel zur Brammenbewegung auf einer Schienenanordnung verfahrbar ist, insbesondere mittels einer Verschiebeeinrichtung. Bei der Wartung, bspw. bei einer Kontrolle der Lagerung der Exzenterwellen des Kurbeltriebs wird die gesamte Baueinheit aus der Presse geschoben und auf einem gut zugänglichen Bauplatz und abseits der Rollgänge, auf denen die heißen Brammen transportiert werden, erfolgt dann die weitere Demontage bzw. Montage der Maschinenelemente der Presse, die besonders hohen Beanspruchungen ausgesetzt sind. Sollten die Wartungsarbeiten einen etwas längeren Zeitraum in Anspruch nehmen, so ist durch das Herausfahren der Baueinheit aus der Stauchpresse und damit aus dem Bereich des Rollgangs soviel Platz im Pressengerüst geschaffen, daß die Brammen ohne betriebliche Behinderung durch das offene Ständerfenster hindurch den nachfolgenden Walzgerüsten zugeführt werden können. Durch diese Maßnahme kann in kurzer Zeit die Walzproduktion in der Straße auch ohne Pressenbetrieb, gegebenenfalls durch Einschieben eines Stauchgerüstes, in vollem Umfang wieder aufgenommen werden.According to claim 1, the generic upsetting press is characterized in that the crankcase with crank drive and feed drive and with the tool carrier are combined to form a structural unit, and that this structural unit can be moved laterally and approximately parallel to the slab movement on a rail arrangement through a stand window of the horizontal press frame, in particular by means of a displacement device. During maintenance, e.g. when checking the bearings of the eccentric shafts of the crank drive, the entire assembly is pushed out of the press and then on a readily accessible site and away from the roller tables on which the hot slabs are transported, further disassembly or assembly takes place the machine elements of the press that are exposed to particularly high loads. Should the maintenance work take a somewhat longer period of time, moving the assembly out of the upsetting press and thus out of the area of the roller table creates so much space in the press stand that the slabs can be fed through the open stand window to the subsequent rolling stands without operational hindrance can. As a result of this measure, the rolling production in the street can be resumed in full in a short time even without a press operation, if necessary by inserting a compression frame.

Eine weitere Verbesserung der Wartung und Kontrolle der hochbelasteten drehenden Teile des Kurbeltriebes ergibt sich dann, wenn die aus der Stauchpresse herausgefahrene Baueinheit auf einer weiteren Schienenanordnung etwa quer zur Brammenbewegung verfahrbar ist. Alle wartungsintensiven oder einer Kontrolle unterliegenden Maschinenteile werden damit noch besser zugänglich. Diese Zugänglichkeit und das Verschieben der Baueinheit aus dem Stauchgerüst wird außerdem dadurch verbessert, daß die Fundamentstützen für das oberhalb der Stauchpresse in einem Getriebegehäuse angeordneten Stirnradgetriebe nur auf einer Seite vorhanden sind und auf der dem Bauplatz zugewandten Gerüstseite sich keine Fundamentstütze befindet.A further improvement in the maintenance and control of the highly stressed rotating parts of the crank mechanism results when the assembly which has been moved out of the upsetting press can be moved on a further rail arrangement approximately transversely to the slab movement. All machine parts that are maintenance-intensive or subject to inspection are thus even more accessible. This accessibility and the displacement of the assembly from the upsetting frame is also improved in that the foundation supports for the spur gear arranged above the upsetting press in a gear housing are only present on one side and there is no foundation support on the scaffolding side facing the building site.

Um die Baueinheit während des Transportes aus der Stauchpresse bzw. in die Stauchpresse zu stabilisieren, ist der Werkzeugträger mittels einer Tragekonsole mit dem Kurbelgehäuse verbunden. Da im Betrieb der Stauchpresse der Werkzeugträger auf einem im Pressengerüst angeordneten Schlitten mit Gleitplatten gelagert ist, muß der Werkzeugträger beim Ausfahren der gesamten Baueinheit von diesen Gleitplatten abgehoben werden, da der Schlitten in dem Pressengerüst zurückbleibt. Das Anheben des Werkzeugträgers erfolgt mittels der am Kurbelgehäuse, vorzugsweise an den Lagerschalen des Kurbeltriebes angeordneten Verbindungselemente der Tragekonsole wie bspw. keilförmig unterlegte Schraubverbindungen.In order to stabilize the structural unit during transport from the compression press or into the compression press, the tool carrier is connected to the crankcase by means of a support bracket. Since, during operation of the upsetting press, the tool carrier is mounted on a slide with slide plates arranged in the press frame, the tool carrier must be lifted off these slide plates when the entire structural unit is extended, since the slide remains in the press frame. The tool carrier is lifted by means of the connecting elements of the support bracket arranged on the crankcase, preferably on the bearing shells of the crank mechanism, such as, for example, wedge-shaped screw connections.

Das Kurbelgehäuse, das auf Gleitplatten in dem Pressengerüst zwischen den Ständerholmen geführt ist, wird am unteren Ständerholm auf beiden Seiten von schwerwiegenden Führungselementen gehalten. Diese Führungselemente müssen zumindest zu der Bauplatzseite hin entfernt werden, damit die Baueinheit aus dem Pressengerüst herausgeschoben werden kann. Zur Vermeidung größerer Montagearbeiten bzw. Demontagearbeiten wird vorgeschlagen, daß diese Führungselemente am Ständerholm angeordnet bleiben und in Richtung auf das Pressenfundament mittels einer Langlochführung absenkbar sind, wozu in den Langlöchern entsprechende Schraubverbindungen gelöst werden müssen.The crankcase, which is guided on sliding plates in the press frame between the uprights, is held on the lower uprights on both sides by heavy guiding elements. These guide elements must be removed at least towards the site so that the assembly can be pushed out of the press frame. To avoid major assembly or disassembly work, it is proposed that these guide elements remain arranged on the upright and can be lowered in the direction of the press foundation by means of an elongated hole guide, for which purpose corresponding screw connections must be loosened in the elongated holes.

Ferner wird die Verbindung des Kurbeltriebes mit den zwischen dem Getriebe und den Exzenterwellen angeordneten kardanischen Antriebswellen möglichst nahe am Kurbelgehäuse gelöst, damit die genannte Baueinheit möglichst einfach und unbehindert aus dem Pressengerüst herausgeschoben werden kann. Da das Kurbelgehäuse in kurzer Zeit von der Anstellvorrichtung und von der am Ständerquerholm abgestützten Ausbalanciereinrichtung vor dem Ausfahren aus dem Gerüst getrennt werden muß, ist dort eine kuppelbare Verbindung vorgesehen.Furthermore, the connection of the crank mechanism to the cardanic drive shafts arranged between the transmission and the eccentric shafts is released as close as possible to the crankcase, so that the above-mentioned structural unit can be pushed out of the press frame as simply and freely as possible. Since the crankcase in a short time from the adjusting device and from the Stand cross member supported balancing device must be separated from the scaffold before extending, there is provided a detachable connection.

Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß die Antriebe des Einlauf-Rollgangs auf einer Einlaufseite der Bramme in die Stauchpresse und die Antriebe des Auslauf-Rollgangs auf der gegenüberliegenden Auslaufseite der Bramme aus der Stauchpresse angeordnet sind, und daß die Baueinheit aus dem Pressengerüst in die jeweils antriebsfreie Seite verfahrbar ist. Durch diese Anordnung konnten die Rollgangsmotoren in dem Bereich untergebracht werden, wo für den Ausbau der Baueinheit keine Demontage der Motore erforderlich ist, so daß während der Wartung der Baueinheit bspw. der Lager oder der Lagerbandagen der Arbeitsrollgang für die Walzproduktion in Betrieb bleibt und die Brammen aus dem Stoßofen durch das nunmehr geöffnete Fenster des Pressengerüsts hindurch zu den nachfolgenden Walzgerüsten zur Weiterverarbeitung geführt werden können.According to a further embodiment of the invention it is provided that the drives of the inlet roller table on one inlet side of the slab into the upsetting press and the drives of the outlet roller table on the opposite outlet side of the slab from the upsetting press are arranged, and that the structural unit from the press stand can be moved into the drive-free side. With this arrangement, the roller table motors could be accommodated in the area where no dismantling of the motors is required for the expansion of the structural unit, so that during the maintenance of the structural unit, for example the bearings or the bearing bandages, the working roller table for rolling production remains in operation and the slabs can be guided out of the pusher furnace through the now open window of the press stand to the subsequent rolling stands for further processing.

Die Stauchpresse weist einen liegenden Gerüstständer 3 auf mit den oberen und unteren Ständerholmen 4, 4' sowie den Querholmen 5, 5'. Ein Kurbelgehäuse 6 ist von einer am Ständerholm 5, 5' abgestützten Anstellvorrichtung 7 sowie mit Hilfe einer am Ständerholm ebenfalls abgestützten Ausbalanciereinrichtung im Gerüstständer 3 der Stauchpresse 1 geführt. Die Anstellung des Kurbelgehäuses erfolgt mit Hilfe einer mechanischen Anstellung. Es ist jedoch auch eine hydraulisch wirkende, Kolben-Zylinder-Konstruktion als Anstellvorrichtung einsetzbar.FIG. 1 shows the longitudinal section through the overhanging upset press 1 for reducing the width of slabs 2 in a hot wide strip roughing mill, the slabs being fed almost continuously from a slab casting plant upstream of the upset press but not shown here. The upsetting press has a horizontal stand 3 with the upper and lower uprights 4, 4 'and the crossbars 5, 5'. A crankcase 6 is guided by an adjusting device 7 supported on the upright 5, 5 ′ and by means of a balancing device likewise supported on the upright in the stand 3 of the upsetting press 1. The crankcase is adjusted using a mechanical adjustment. However, a hydraulically acting piston-cylinder construction can also be used as the adjusting device.

Zu beiden Seiten der Bramme 2 sind Preßwerkzeuge 9 an einem Werkzeugträger 10 angeordnet. Das Preßwerkzeug und der Werkzeugträger haben einen senkrecht zur Bramme 2 wirkenden Reduktionsantrieb 11 und einen parallel zur Bramme 2 wirkenden Vorschubantrieb 12. Der Reduktionsantrieb und der Vorschubantrieb sind in dem Kurbelgehäuse 6 angeordnet. Der Reduktionsantrieb wird dadurch gebildet, daß jeder Werkzeugträger 10 mit Hilfe eines von zwei Exzenterwellen 13 betätigten Lenkersystems, welches zwei Pleuel 14 enthält, im wesentlichen in Richtung der in der Breite zu reduzierenden Bramme 2 bewegbar ist. Der im wesentlichen in Richtung des Brammenvorschubs wirkende Vorschubantrieb 12 greift am Werkzeugträger 10 an und ist am Kurbelgehäuse 6 abgestützt, in welchem die zwei Exzenterwellen 13 gelagert sind. Die Exzenterwellen stehen mit kardanisch gelagerten Gelenkwellen 15 in Verbindung, die mit einem Stirnradgetriebe 16 verbunden sind. Der Getriebekasten 17 ist oberhalb der Stauchpresse auf einer Fundamentstütze 18 gehalten. Die Eingangswelle 19 des Stirnradgetriebes ist mit einem Antriebsmotor 20 gekuppelt. Die Fundamentstütze 18 steht seitlich von der Stauchpresse 1 auf dem Fundament 21 auf und kragt seitlich mit einem Kopfteil 22 über die Stauchpresse 1. Der überkragende Kopfteil trägt den Getriebekasten mit Stirnradgetriebe.Pressing tools 9 are arranged on a tool carrier 10 on both sides of the slab 2. The pressing tool and the tool carrier have a reduction drive 11 acting perpendicular to the slab 2 and a feed drive 12 acting parallel to the slab 2. The reduction drive and the feed drive are arranged in the crankcase 6. The reduction drive is formed in that each tool carrier 10 can be moved essentially in the direction of the slab 2 to be reduced in width with the aid of a steering system operated by two eccentric shafts 13 and containing two connecting rods 14. The feed drive 12, which acts essentially in the direction of the slab feed, engages on the tool carrier 10 and is supported on the crankcase 6, in which the two eccentric shafts 13 are mounted. The eccentric shafts are connected to cardan-mounted cardan shafts 15 which are connected to a spur gear 16. The gear box 17 is held on a foundation support 18 above the upsetting press. The input shaft 19 of the spur gear is coupled to a drive motor 20. The foundation support 18 stands laterally from the upsetting press 1 on the foundation 21 and projects laterally with a head part 22 over the upsetting press 1. The projecting head part carries the gear box with spur gear.

Das Kurbelgehäuse 6 mit dem im Kurbelgehäuse angeordneten und aus den Exzenterwellen 13 und den Pleuel 14 bestehenden Kurbeltrieb 23 und mit dem Vorschubantrieb 12 sowie mit dem Werkzeugträger 8 sind zu einer Baueinheit 24 zusammengefaßt (Fig. 2). Diese Baueinheit ist durch ein Ständerfenster 25 des liegenden Pressengerüsts 3 seitlich und etwa parallel zur Brammenbewegung auf einer Schienenanordnung 26 verfahrbar. Diese Anordnung besteht im vorliegenden Beispiel aus zwei mit Gleitplatten belegten und mit Abstand zueinander verlaufenden Schienensträngen 26' mit entsprechenden Schienenteilen, die zwischen den unteren Ständerholmen 4 angeordnet sind. Das Verschieben der Baueinheit 24 erfolgt mit Hilfe einer Verschiebeeinrichtung 27, bspw. einer Kolben-Zylinder-Einheit 28. Eine weitere Schienenanordnung 29 verläuft quer zur Brammenbewegung, so daß die Baueinheit 24 zunächst auf der Schienenanordnung 26 parallel zur Brammenbewegung aus dem Stauchgerüst herausgeschoben und anschließend auf der Schienenanordnung 29 um einen bestimmten Weg quer zur Brammenbewegung auf einen frei zugänglichen Bauplatz verschoben werden kann.The crankcase 6 with the crank drive 23 arranged in the crankcase and consisting of the eccentric shafts 13 and the connecting rods 14 and with the feed drive 12 and with the tool carrier 8 are combined to form a structural unit 24 (FIG. 2). This structural unit can be moved laterally and approximately parallel to the slab movement on a rail arrangement 26 through a stand window 25 of the lying press frame 3. In the present example, this arrangement consists of two rail tracks 26 ′ covered with sliding plates and spaced apart from one another, with corresponding rail parts which are arranged between the lower uprights 4. The assembly 24 is displaced with the aid of a displacement device 27, for example a piston-cylinder unit 28. Another rail arrangement 29 extends transversely to the slab movement, so that the assembly 24 is first pushed out of the compression frame on the rail arrangement 26 parallel to the slab movement and then can be moved on the rail arrangement 29 by a certain path transversely to the slab movement onto a freely accessible construction site.

Der liegende Werkzeugträger 10 und die Pleuel 14 sind auf einem Schlitten 30 mit nicht näher dargestellten Gleitplatten üblicher Bauart gleitend abgestützt. Zur Stabilisierung der Baueinheit während des Verfahrens aus dem Stauchgerüst wird der Werkzeugträger 10 mit Hilfe einer Tragekonsole 31 mit dem Kurbelgehäuse 6 verbunden, und zwar vorzugsweise mit den Lagerschalen des Kurbeltriebes. Mit Hilfe speziell ausgebildeter Verbindungselemente, bspw. einer Schraubverbindung mit entsprechend geformten Unterlegkeilen für die Tragekonsole, wird der Werkzeugträger 10 von dem mit dem Pressengerüst 3 verbundenen und den Werkzeugträger im Betrieb abstützenden Schlitten bzw. von dessen Gleitplatten 30 anhebbar.The lying tool carrier 10 and the connecting rods 14 are slidably supported on a slide 30 with sliding plates of a conventional type not shown. To stabilize the structural unit during the process from the compression frame, the tool carrier 10 is connected to the crankcase 6 with the aid of a support bracket 31, preferably with the bearing shells of the crank mechanism. With the aid of specially designed connecting elements, for example a screw connection with correspondingly shaped chocks for the carrying console, the tool carrier 10 can be lifted by the slide connected to the press stand 3 and supporting the tool carrier during operation or by its sliding plates 30.

Die Baueinheit 24 wird mit folgenden Demontagemaßnahmen zum Herausfahren aus dem Pressengerüst vorbereitet. Die zumindest an den unteren Ständerholmen 4 des Pressengerüsts 3 angeordneten Führungselemente 32 für das Kurbelgehäuse 6 werden in Richtung auf das Pressenfundament 21 in einer in den Führungselementen angeordneten Langlochführung abgesenkt. Die zwischen Kurbeltrieb 23 und den antreibenden Gelenkwellen 15 angeordnete Trenn- bzw. Verbindungsvorrichtung 33 wird gelöst. Dies kann durch eine Flanschverbindung erfolgen, die im Bereich zwischen der Oberkante des Kurbelgehäuses 6 und der Unterkante der oberen Ständerholme 4' des Pressengerüsts angeordnet ist. Ferner wird die das Kurbelgehäuse 6 am Ständerquerholm 5 abstützende Anstellvorrichtung 7 sowie die ebenfalls am Ständerholm 5 abgestützte Ausbalanciereinrichtung 8 mit Hilfe der kuppelbaren Verbindung 34 vom KUrbelgehäuse gelöst. Nachdem sämtliche hydraulischen Anschlüsse von der Baueinheit 24 gelöst wurden, ist diese von der Verschiebeeinrichtung 27 aus dem Fenster des Gerüstständers auf der Schienenanordnung 26 und 29 auf den Bauplatz 35 verschiebbar. Insbesondere Fig. 3 zeigt den seitlich von der Stauchpresse 1 liegenden Bauplatz 35, der von allen Seiten frei zugänglich ist, so daß die Wartung bzw. Kontrolle der hochbelasteten Maschinenteile der Baueinheit 24 wie Lager etc. ungehindert und schnell durchgeführt werden kann.The assembly 24 is prepared with the following disassembly measures for moving out of the press frame. The guide elements 32 for the crankcase 6, which are arranged at least on the lower uprights 4 of the press frame 3, are lowered in the direction of the press foundation 21 in an elongated hole guide arranged in the guide elements. The separating or connecting device 33 arranged between the crank mechanism 23 and the driving cardan shafts 15 is released. This can be done by means of a flange connection which is arranged in the area between the upper edge of the crankcase 6 and the lower edge of the upper uprights 4 'of the press frame. Furthermore, the adjusting device 7, which supports the crankcase 6 on the stator cross member 5, and the balancing device 8, which is also supported on the stator post 5, are detached from the plug housing by means of the detachable connection 34. After all hydraulic connections have been released from the assembly 24, the latter can be displaced from the window of the scaffold stand on the rail arrangement 26 and 29 onto the construction site 35 by the displacement device 27. In particular, Fig. 3 shows the site 35 lying to the side of the upsetting press 1, which is freely accessible from all sides, so that the maintenance or control of the highly stressed machine parts of the unit 24 such as bearings etc. can be carried out unimpeded and quickly.

Die freie Zugänglichkeit des Bauplatzes 35 wird dadurch erreicht, daß die Antriebe 36 des Einlauf-Rollgangs 37 ausschließlich auf der einen Einlaufseite 38 der Bramme 2 in die Stauchpresse 1 angeordnet sind, und daß die Antriebe 39 des Auslauf-Rollgangs 40 auf der gegenüberliegenden Auslaufseite 41 der Bramme 2 aus der Stauchpresse 1 angeordnet sind, so daß die Baueinheit 24 aus dem Pressengerüst in die jeweils von den Antrieben freie Seite verfahrbar ist. Falls also eine längere Wartung der Baueinheit 24 auf dem Bauplatz 35 erforderlich wird, bleiben die Arbeitsrollgänge, auf denen die Bramme 2 zu den nachfolgenden Walzgerüsten geführt werden, betriebsbereit, so daß die Walzproduktion auch ohne die Stauchpresse gegebenenfalls mit einem anderen in die Walzlinie eingefahrenen Stauchgerüst aufgenommen werden kann.The free accessibility of the building site 35 is achieved in that the drives 36 of the infeed roller table 37 are arranged exclusively on one inlet side 38 of the slab 2 in the upsetting press 1, and in that the drives 39 of the outlet roller table 40 on the opposite outlet side 41 the slab 2 are arranged from the upsetting press 1, so that the assembly 24 can be moved out of the press stand into the side free of the drives. So if a longer maintenance of the assembly 24 on the site 35 is required, the work roller tables on which the slab 2 are guided to the subsequent roll stands remain ready for operation, so that the roll production can also be carried out with another press stand that has been moved into the rolling line without the upsetting press can be included.

Die Montage der Baueinheit 24 in die Stauchpresse 1 erfolgt in umgekehrter Reihenfolge zu den oben beschriebenen Demontage-Maßnahmen. Die Baueinheit 24 wird vom Bauplatz 35 auf der Schienenanordnung 29, 26 in das Ständerfenster des Gerüstständers 3 zurückgeschoben, die Führungselemente 32 werden in der Langlochführung nach oben gezogen und seitlich verankert; die Ausbalanciereinrichtung und die Anstellvorrichtung werden an das Kurbelgehäuse angekuppelt, die Verbindungsvorrichtung von Gelenkwellen 15 und Exzenterwellen 13 wird gekoppelt und die den Werkzeugträger 10 stabilisierende Tragekonsole 31 wird mit den Verbindungselementen so gelöst, daß der Werkzeugträger auf die Gleitplatten 30 abgesenkt wird. Die Stauchpresse ist dann betriebsbereit. In Fig. 1 ist die zwischen den Preßwerkzeugen 9 angeordnete Bramme 2 zu sehen, die im Betrieb von auf der Einlaufseite 38 und der Auslaufseite 41 angeordneten Treiberrollen 43 durch die Stauchpresse bewegt wird und während des Stauchens von oberhalb und unterhalb der Bramme angeordneten Halterollen 43 zur Vermeidung von Aufwölbungen geführt wird.The assembly of the assembly 24 in the upsetting press 1 is carried out in the reverse order to the disassembly measures described above. The assembly 24 is pushed back from the site 35 on the rail arrangement 29, 26 into the stand window of the scaffold stand 3, the guide elements 32 are pulled upwards in the slot guide and anchored to the side; the balancing device and the adjusting device are coupled to the crankcase, the connecting device of the cardan shafts 15 and eccentric shafts 13 is coupled and the support bracket 31 which stabilizes the tool carrier 10 is released with the connecting elements in such a way that the tool carrier is lowered onto the sliding plates 30. The upsetting press is then ready for operation. In Fig. 1 the slab 2 arranged between the pressing tools 9 can be seen, which is moved during operation of driving rollers 43 arranged on the inlet side 38 and the outlet side 41 through the upsetting press and during of upsetting from above and below the slab arranged holding rollers 43 is guided to avoid bulging.

Es wird ersichtlich, daß mit den oben beschriebenen Maßnahmen die eingangs gestellte Aufgabe technisch und wirtschaftlich in vorteilhafter Weise gelöst wird und daß dadurch die Verfügbarkeit der Stauchpresse und die Proktuktivität einer Walzstraße, insbesondere einer Warmbreitband-Vorstraße erhöht wird.It can be seen that the above-described measures solve the technical and economic problem in an advantageous manner and that this increases the availability of the upsetting press and the productivity of a rolling mill, in particular a hot strip mill.
