Abstract

The invention relates to a straightening plant for metal strips with a stretch-bending apparatus. The stretch-bending apparatus is arranged between two drivers which replace otherwise customary sets of tensioning drums and produce the strip tension required for stretch-bend-straightening. Threading of the respective strip is thereby facilitated and the strip losses due to the absence of strip treatment which otherwise have to be accepted are furthermore considerably reduced.

Description

Die Erfindung betrifft eine Richtanlage für endliche Bänder, insbesondere Metallbänder, mit einem Aufwickelhaspel, einem Abwickelhaspel und einer zwischen beiden Wickelhaspeln angeordneten Streckbiegevorrichtung, wie sie z.B. aus dem Dokument GB-A- 2197233 bekannt ist.The invention relates to a straightening system for finite strips, in particular metal strips, with a take-up reel, a take-up reel and a stretch-bending device arranged between the two take-up reels, as described e.g. is known from document GB-A-2197233.

Bei diskontinuierlichen Bandbehandlungslinien wie beispielsweise Streckbiegerichtlinien, Streckbiegericht/Dressierlinien od. dgl., in denen nur einzelne Coils gefahren werden, treten an den beiden Bandenden des jeweils zu behandelnden Bandes Bandverluste von jeweils etwa 15 - 20 m auf. Diese Bandverluste resultieren insbesondere aus den bei bekannten Richtanlagen regelmäßig eingesetzten Brems- und Zugspanntrommelsätzen, welche die für den Streckbiegebereich erforderlichen und verhältnismäßig hohen Spannzüge erzeugen. Die Spannzüge können erst aufgebaut werden, wenn Aufwickelhaspel und Abwickelhaspel den Vorzug bzw. Rückzug für die Spanntrommelsätze erzeugen. - Der Spannzug für das Streckbiegerichten - darunter ist ein wechselweises Biegen unter hohem Bandzug zu verstehen - liegt je nach Bandabmessung und Streckgrenze für z. B. Stahlbänder mit Banddicken von 1,0 bis 4,0 mm bei einer Breite von 1.500 mm bei etwa 8 - 20 t. Ein solcher Spannzug kann nicht von den Wickelhaspeln erbracht werden, da der übliche spezifische Wickelzug bei 10 - 15 N/mm² liegt. Insbesondere stört der nicht gerichtete Bandanfang, der in das Coil eingewickelt werden muß und erst beim Entverbraucher abgeschnitten werden kann. - Ein weiterer Nachteil ist darin zu sehen, daß der jeweilige Bandanfang in die Spanntrommelsätze neu eingefädelt werden muß. Daraus resultiert ein erheblicher Zeit- und Produktionsverlust. Ferner lassen sich dicke Bänder nur mit Hilfe eines sogenannten Pilotbandes oder eines Seiles einfädeln.In the case of discontinuous strip treatment lines, such as stretch bending guidelines, stretch bending lines / skin pass lines or the like, in which only individual coils are run, strip losses of about 15-20 m each occur at the two strip ends of the strip to be treated. These strip losses result in particular from the brake and tension drum sets which are regularly used in known straightening systems and which generate the relatively high tensioning trains required for the stretch bending area. The tensioning straps can only be built up when the reel-up and decoilers produce the advance or retreat for the tensioning drum sets. - The tensioning cable for stretch bending straightening - this means an alternate bending under high strip tension - is depending on the strip size and the yield point for z. B. Steel strips with strip thicknesses of 1.0 to 4.0 mm with a width of 1,500 mm at about 8 - 20 t. Such a tension tension cannot be produced by the winding reels because the usual specific tension tension is 10 - 15 N / mm². In particular, the non-directional start of the strip, which has to be wrapped in the coil and can only be cut off by the de-consumer, is a problem. - Another disadvantage is the fact that the respective beginning of the tape must be re-threaded into the tensioning drum sets. This results in a considerable loss of time and production. Furthermore, thick tapes can only be threaded using a so-called pilot tape or a rope.

Der Erfindung liegt die Aufgabe zugrunde, eine Richtanlage für endliche Bänder, insbesondere Metallbänder, der eingangs beschriebenen Art zu schaffen, die es in einfacher Weise ermöglicht, ohne zeitraubendes Einfädeln und große Bandverluste Bänder in einer diskontinuierlichen Bandlinie umzuwickeln und zu richten bzw. zu richten und zu dressieren.The invention has for its object to provide a straightening system for finite strips, in particular metal strips, of the type described in the opening paragraph, which makes it possible in a simple manner to wrap and straighten or straighten strips in a discontinuous strip line without time-consuming threading and large strip losses to train.

Diese Aufgabe löst die Erfindung bei einer gattungsgemäßen Richtanlage dadurch, daß in Bandlaufrichtung vor und hinter der Streckbiegevorrichtung jeweils ein Treiber oder ein Dressiergerüst und ein Treiber angeordnet sind. Im Rahmen der Erfindung ist also die Streckbiegevorrichtung zwischen zwei Treibern oder einem Treiber und einem Dressiergerüst angeordnet, sind ihrerseits die beiden Treiber bzw. der Treiber und das Dressiergerüst zwischen den Wickelhaspeln und der Streckbiegevorrichtung angeordnet. - Die Erfindung geht von der Erkenntnis aus, daß sich der in Bandlaufrichtung hinter der Streckbiegevorrichtung angeordnete Treiber als Zugtreiber und der in Bandlaufrichtung vor der Streckbiegevorrichtung angeordnete Treiber als Bremstreiber bzw. das Dressiergerüst als bremsendes Dressiergerüst derart antreiben lassen, daß anstelle der sonst verwendeten Zug- und Bremsspanntrommelsätze lediglich diese Treiber bzw. Treiber und Dressiergerüst erforderlich sind, um die für das Streckbiegerichten erforderlichen hohen Spannzüge zu erzeugen. Es werden also die sonst üblichen Zug- und Bremsspanntrommelsätze durch die Treiber bzw. den Treiber und das Dressiergerüst ersetzt. Dadurch lassen sich die hohen Spannzüge im Streckbiegebereich im übrigen auch unabhängig davon erzeugen, ob die Wickelzüge bereits aufgebaut sind oder nicht. Jedenfalls lassen sich die verlangten hohen Spannzüge durch lediglich die einstellbare Andrückkraft der angetriebenen Treibrollen bzw. Dressierwalzen erzeugen. Treiber und ggf. Dressiergerüst reduzieren die sonst bei Spanntrommelsätzen am Bandanfang und am Bandende auftretenden Bandverluste ganz erheblich, weil sich diese Bandverluste auf die behandlungsfreie Strecke zwischen Zugtreiber und Streckbiegevorrichtung bzw. Streckbiegevorrichtung und Bremsteiber bzw. Dressiergerüst reduzieren. Hinzu kommt, daß das Einfädeln des jeweils zu behandelnden Bandes unschwer mit Hilfe der Treiber bzw. des Dressiergerüstes und der in der Streckbiegevorrichtung anstellbaren Streckbiegerollen erfolgen kann, so daß insoweit nicht länger erhebliche Zeit- und Produktionsverluste in Kauf genommen werden müssen. Da im übrigen immer größere Ansprüche an die Planheit der Bänder und insbesondere Metallbänder gestellt werden, schafft die erfindungsgemäße Richtanlage mit einfachen Mitteln die Möglichkeit, ohne zeitraubendes Einfädeln und große Bandverluste Bänder und insbesondere Metallbänder in einer diskontinuierlichen Bandlinie umzuwickeln, zu richten bzw. zu richten und zu dressieren. - Darin sind die wesentlichen durch die Erfindung erreichten Vorteile zu sehen.This object is achieved by the invention in a straightening system of the generic type in that a driver or a skin pass mill and a driver are arranged in front of and behind the stretch bending device in the belt running direction. In the context of the invention, therefore, the stretch bending device is arranged between two drivers or a driver and a skin pass mill, in turn the two drivers or the driver and the skin pass mill are arranged between the winding reels and the stretch bending device. - The invention is based on the knowledge that the driver arranged behind the stretch bending device in the direction of belt travel and the driver arranged in front of the stretch bending device in the direction of belt travel or the skin pass mill as a braking skin pass mill can be driven such that instead of the tension train otherwise used and brake tensioning drum sets, only these drivers or skin pass mill are required in order to generate the high tensioning trains required for stretch bending straightening. So the usual tension and brake tension drum sets are replaced by the drivers or the driver and the skin pass mill. As a result, the high tensioning cables in the stretch bending area can also be used independently generate whether the winding trains are already set up or not. In any case, the required high tension pulls can only be generated by the adjustable pressing force of the driven drive rollers or skin pass rollers. Drivers and the skin pass mill, if any, significantly reduce the belt losses that usually occur at the start and end of the tensioning drum set because these belt losses are reduced to the treatment-free distance between the train driver and the stretch bending device or stretch bending device and the brake driver or skin pass mill. In addition, the threading of the strip to be treated in each case can be carried out easily with the aid of the drivers or the skin pass mill and the stretching bending rollers which can be set in the stretching bending device, so that considerable time and production losses no longer have to be accepted. Since more and more demands are being made on the flatness of the strips and in particular metal strips, the straightening system according to the invention provides simple means for wrapping, straightening or straightening strips and in particular metal strips in a discontinuous strip line without time-consuming threading and large strip losses to train. - This shows the main advantages achieved by the invention.

Nach einem weiteren Vorschlag der Erfindung ist dem in Bandlaufrichtung vor der Streckbiegevorrichtung angeordneten Treiber oder Dressiergerüst eine Zugmeßvorrichtung, z. B. Zugmeßrolle zum Zugregeln des Treibers oder des Dressiergerüstes zugeordnet. Mittels dieser Zugmeßvorrichtung wird der Antrieb des Bremstreibers bzw. Dressiergerüstes zugmäßig geführt. Der eingestellte Richteffekt bleibt dadurch konstant, auch wenn die Wickelzüge der Wickelhaspel zu- oder abgeschaltet werden. Dagegen ist der Zugtreiber der Speedmaster der Bandlinie. Die Antriebswellen der Treiber und der Dressierwalzen werden von separaten Antriebsmotoren einzeln angetrieben.According to a further proposal of the invention, the driver or skin pass mill arranged in the tape running direction upstream of the stretch bending device is a tension measuring device, e.g. B. tension measuring roller for tension control of the driver or skin pass mill assigned. By means of this tension measuring device, the drive of the brake driver or skin pass mill is guided in tension. The set straightening effect remains constant, even if the winding units of the winding reel are switched on or off. In contrast, the train driver is the Speedmaster the band line. The drive shafts of the drivers and skin pass rollers are individually driven by separate drive motors.
