Abstract

During the production of spiral rebated tubes, the parts of a device, in particular forming heads are to be adjusted to the diameters of produced tubes. The inventive quick-clamp device (1) comprises an adjustable carriage (4) which replaces currently used bolted joints and makes it possible to reduce adjustment time. A bearing-bush (8) provided with a drilled hole (13) and an external thread (8') which are centrally screwed in a U-shaped guiding system (3). Mutually opposite holes (7a, 7b) which are used for receiving a shaft (6) provided with a transversal pin (18) are embodied in the bearing-bush (8). A rotatable handle bar (9) allows the shaft (6) to perform an axial motion inside the holes (7a). Due to a light torsion, the transversal pin engages the extremity of the hole (7a) in the hole (7b), transmits a moment of rotation which performs an action on the handle bar (9) in the bearing-bush (8) and releases the adjustable carriage (4).

Description

Die Erfindung bezieht sich auf eine Schnellspannvorrichtung gemäss dem Oberbegriff des Patentanspruchs (siehe z.B. US-A-4 706 481 ).The invention relates to a quick-release device according to the preamble of the claim (see, for example US-A-4,706,481 ).

Bei der Herstellung von Wickelfalzrohren (auch Spiralrohre genannt) für Lüftungsanlagen, werden für jeden Rohrdurchmesser sogenannte Formköpfe verwendet, in denen Blechstreifen (Bänder) zu einem Rohr geformt werden. Diese massiv ausgestalteten Formköpfe sind mit einer bridenartigen Klemmvorrichtung, mittels drei oder vier Schrauben, lösbar mit der Falzschliessmaschine verbunden.In the production of spiral ducts (also called spiral pipes) for ventilation systems, so-called forming heads are used for each pipe diameter, in which metal strips (strips) are formed into a tube. This solid designed forming heads are connected to a Brideartigen clamping device, by means of three or four screws, releasably connected to the Falzschliessmaschine.

Werden auf der gleichen Maschine Rohre unterschiedlicher Durchmesser hergestellt, so resultiert eine relativ grosse Umrüstzeit zwischen den einzelnen Fabrikationsabläufen. Berücksichtigt man die hohe Leistung solcher Maschinen - z.B. bis zu 10 m Lüftungsrohr von 150 mm Durchmesser pro Minute - so erscheint grundsätzlich eine einzige Falzschliessmaschine als ausreichend für die Herstellung auch grosser Lüftungsanlagen mit verschiedenen Rohrdurchmessern.If pipes of different diameters are produced on the same machine, the result is a relatively large changeover time between the individual production processes. Considering the high performance of such machines - e.g. up to 10 m ventilation pipe with a diameter of 150 mm per minute - in principle, a single seam locking machine seems sufficient for the production of even large ventilation systems with different pipe diameters.

Es ist daher Aufgabe der vorliegenden Erfindung die den Betriebsablauf verzögernden und störenden Umrüstzeiten zu reduzieren und die Handhabung zu vereinfachen. Der Abbau eines Formkopfes und die Installation eines anderen Formkopfes mit dem aktuell erforderlichen Durchmesser soll problemlos und in kurzer Zeit erfolgen.It is therefore an object of the present invention to reduce the operation delays and disturbing changeover times and to simplify handling. The dismantling of a mold head and the installation of another mold head with the currently required diameter should be done easily and in a short time.

Es ist zudem Aufgabe der Erfindung die Vorrichtung derart auszugestalten, dass sie auch zum Aufspannen anderer Teile, Baugruppen und/oder Geräte an Maschinen zur Herstellung und/oder Bearbeitung von Wickelfalzrohren Verwendung finden kann, resp. an diese anpassbar ist.It is also an object of the invention to design the device such that it can also be used to clamp other parts, assemblies and / or devices on machines for production and / or processing of spiral ducts can be used, respectively. adaptable to this.

Es soll somit eine Schnellspannvorrichtung geschaffen werden, die insbesondere keine Werkzeuge wie Innensechskanntschlüssel, Steck- oder Gabelschlüssel erfordert zu deren Betrieb, trotzdem eine hohe Klemmwirkung ausübt und sich auch im harten Einsatz nicht öffnet oder verschiebt.It is therefore intended to provide a quick-release device which, in particular, does not require any tools such as a hexagon wrench, plug wrench or open-end wrench to operate, yet exerts a high clamping effect and does not open or move even in hard use.

Diese Aufgabe ist durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

In nachfolgenden abhängigen Ansprüchen sind Weiterbildungen der Erfindung charakterisiert sowie bevorzugte Verwendungen aufgeführt.In subsequent dependent claims further developments of the invention are characterized and preferred uses listed.

Die Ausgestaltung nach Anspruch 2 ist sehr raumsparend und insbesondere bevorzugt, weil die Welle kurz sein kann und damit ebenfalls die Einbaulänge des Schiebers reduziert ist.The embodiment according to claim 2 is very space-saving and particularly preferred because the shaft can be short and thus also the installation length of the slider is reduced.

Die Variante nach Anspruch 3 erfordert eine etwas längere Bauweise, ist aber kinetisch günstiger und lässt sich mit geringeren Kräften entspannen.The variant according to claim 3 requires a slightly longer design, but is kinetically cheaper and can be relaxed with less force.

Eine bevorzugte Verbindung der Welle mit einem handelsüblichen Drehhebel ist in Anspruch 4 beschrieben.A preferred connection of the shaft with a commercially available rotary lever is described in claim 4.

Die sehr einfache Ausgestaltung der Führung ermöglicht eine rasche Montage der Vorrichtung auf der jeweiligen Maschine, Anspruch 5.The very simple design of the guide allows rapid assembly of the device on the respective machine, claim 5.

Gemäss Anspruch 6 ist der Schieber nach Art einer Klemmbride ausgeführt, was dessen universellen Einsatz in Verbindung mit an sich bekannten Geräten ermöglicht.According to claim 6, the slider is designed in the manner of a clamping strap, which allows its universal use in conjunction with devices known per se.

Die bevorzugte Ausgestaltung der Ausnehmungen in der als Spannmutter dienenden Lagerbuchse ist in Anspruch 7 aufgezeigt und herstellungstechnisch günstig. Besonders vorteilhaft ist die resultierende kurze Einbaulänge.The preferred embodiment of the recesses in serving as a clamping nut bearing bush is shown in claim 7 and manufacturing technology favorable. Particularly advantageous is the resulting short installation length.

Die Ansprüche 8 bis 10 betreffen bevorzugte Verwendungen des Erfindungsgegenstands, sind aber keineswegs als abschliessend zu betrachten.The claims 8 to 10 relate to preferred uses of the subject invention, but are by no means to be considered exhaustive.

Nachfolgend wird an Hand von Zeichnungen ein Ausführungsbeispiel der Erfindung näher beschrieben:An exemplary embodiment of the invention will be described in more detail below with reference to the drawings.

In Figur 1 ist mit 20 eine Maschine zur Herstellung von Wickelfalzrohren bezeichnet. Auf dieser an sich bekannten und weitverbreiteten Maschine 20 (Hersteller: SPIRO S.A. CH-3178 Boesingen) werden Blechstreifen über eine Führungswelle 10 gestossen und in einem Formkopf 11 zu Rohren 12 geformt, wobei deren spiralförmige Falze 12' gleichzeitig geschlossen werden. Der Formkopf 11 ist durch eine Schnellspannvorrichtung 1 mittels deren Schieber 4 gegen einen in Fig. 1 verdeckten Anschlag auf der Maschine 20 gespannt und dadurch fixiert. Der Schieber 4 ist durch seitliche Wangen 3' einer U-förmigen Führung 3 gleitfähig gehalten.In FIG. 1, denoted by 20 is a machine for the production of spiral ducts. On this known and widespread machine 20 (manufacturer: SPIRO S.A. CH-3178 Boesingen) sheet metal strips are pushed over a guide shaft 10 and formed in a forming head 11 into tubes 12, wherein the spiral folds 12 'are closed simultaneously. The forming head 11 is clamped by a quick-release device 1 by means of the slide 4 against a hidden in Fig. 1 stop on the machine 20 and thereby fixed. The slider 4 is held by lateral cheeks 3 'of a U-shaped guide 3 slidably.

Die Führung 3 ist durch zwei Innensechskanntschrauben 2 auf der Maschine 20 festgeschraubt, wobei die für die bisher verwendeten, aufgeschraubten Klemmen, vorgesehenen Gewindebohrungen benutzt sind.The guide 3 is screwed by two hexagon socket screws 2 on the machine 20, wherein the threaded holes used for the previously used, screwed terminals are used.

Die Fabrikationsangaben für den jeweils herzustellenden Rohrtyp (mit Durchmesser- und Blechdickenangaben) sind auf einer grosszügig dimensionierten Platte 11a eingegossen.The manufacturing specifications for each type of tube to be produced (with diameter and thickness specifications) are cast on a generously dimensioned plate 11a.

Betätigt wird die Schnellspannvorrichtung durch einen frontseitigen Drehhebel 9; siehe auch Fig. 2.The quick-release device is actuated by a front rotary lever 9; see also Fig. 2.

In dieser Figur erkennt man die vorgängig beschriebenen Teile der Spannvorrichtung 1; die Spannrichtung des Schiebers 4 ist mit einem Pfeil S bezeichnet. Angedeutet ist eine zentrale Lagerbuchse 8 mit Ausnehmungen 7. In einer vergrösserten Darstellung Fig. 3 und Fig. 4 ist die Lagerbuchse 8 vollständig dargestellt. Sie besitzt ein Aussengewinde 8' (Feingewinde M 50 x 1,5), eine zentrale Bohrung 13 und mit dieser verbundene Ausnehmungen 7a und 7b , wobei die Ausnehmungen 7a durchgehend sind.In this figure, one recognizes the previously described parts of the clamping device 1; the clamping direction of the slider 4 is indicated by an arrow S. A central bearing bush 8 with recesses 7 is indicated. In an enlarged view in FIGS. 3 and 4, the bearing bush 8 is shown completely. It has an external thread 8 '(fine thread M 50 x 1.5), a central bore 13 and associated with these recesses 7a and 7b, wherein the recesses 7a are continuous.

Figur 3 zeigt die Lagerbuchse 8 von der Seite des Drehhebels 9 betrachtet mit ihren ersten Ausnehmungen 7a.FIG. 3 shows the bearing bush 8 viewed from the side of the rotary lever 9 with its first recesses 7a.

Die Fig. 4 stellt die Lagerbuchse 8 von der Spannseite her gesehen dar; sichtbar sind bayonettverschlussartige Ausnehmungen (Vertiefungen) 7b.Fig. 4 shows the bearing bush 8 seen from the tension side; Bayonet-like recesses (recesses) 7b are visible.

Das Zusammenspiel der einzelnen Bauelemente ist, mit weiteren Einzelheiten, der Fig. 5 zu entnehmen.The interaction of the individual components is, with further details, the Fig. 5 refer.

Die zentrale Welle 6 ist beidseitig abgesetzt und weist auf der Seite des Hebels 9 ein Aussengewinde 19 und auf der Spannseite S eine Ringnut 17 auf. Gleitfähig gelagert ist die Welle 6 in der Bohrung 13 der Lagerbuchse 8, die in ein zentrales Innengewinde in der Führung 3 eingeschraubt ist. Ein Querbolzen 18 ragt beidseitig aus einer entsprechenden Bohrung 16 aus der Welle 6 heraus und liegt mit seinen Seitenflächen in der zweiten Ausnehmung 7b der Buchse 8.The central shaft 6 is offset on both sides and has an external thread 19 on the side of the lever 9 and an annular groove 17 on the clamping side S. Skidably mounted, the shaft 6 in the bore 13 of the bearing bush 8, which is screwed into a central internal thread in the guide 3. A transverse pin 18 protrudes from both sides of a corresponding bore 16 of the shaft 6 and is located with its side surfaces in the second recess 7b of the socket. 8

Damit sich der Drehhebel 9 nicht unbeabsichtigt vom Gewinde 19 löst, ist er zusätzlich mit einem hier nicht eingezeichneten Schwerspann-Stift mit der Welle 6 verbunden.So that the rotary lever 9 does not inadvertently disengage from the thread 19, it is additionally connected to the shaft 6 with a heavy-duty pin not shown here.

Eine Stiftschraube 5 (Gewindestift) ist oberseitig in den Schieber 4 eingeschraubt und ragt mit seiner abgesetzten Spitze in die Ringnut 17 der Welle 6. - Dies bewirkt eine einfache Umsetzung der Drehbewegung und des Vorschubs der Welle 6 in eine reine Linearbewegung des Schiebers 4. Bei der Vorschubbewegung in Richtung S, erfolgt die Kraftübertragung über die Flanke einer Andrehung 6' auf der Welle 6. Die bridenartige Form des Schiebers 4 ist ebenfalls ersichtlich und entspricht der gewohnten Klemmwirkung bisheriger Montagearten für Formköpfe.A stud 5 (threaded pin) is screwed into the upper side of the slide 4 and protrudes with its stepped tip in the annular groove 17 of the shaft 6. This causes a simple implementation of the rotational movement and the advance of the shaft 6 in a pure linear movement of the slide 4. Bei the feed movement in the direction S, the power transmission via the edge of a Andrehung 6 'on the shaft 6. The bridal-like shape of the slide 4 is also visible and corresponds to the usual clamping action of previous types of mounting molds.

Die Installation eines Formkopfes 11 erfolgt in einfachster Weise:The installation of a forming head 11 is done in the simplest way:

Dieser wird - wie bisher - mit seiner Auflagefläche auf den Maschinentisch gelegt und randseitig unter einen stirnseitigen Anschlag (nicht gezeichnet) geschoben. Daraufhin wird der Schieber 4, mit dem Drehhebel 9 in Spannrichtung S an den Fuss bzw. an die hebelseitige Stirnfläche des Formkörpers 11 geschoben; dafür muss sich der Querbolzen 18 in den ersten Ausnehmungen 7a befinden: Winkelstellung I des Drehhebels 9 gemäss Fig. 1.This is - as before - placed with its bearing surface on the machine table and the edge under a frontal stop (not shown) pushed. Then, the slider 4 is pushed with the rotary lever 9 in the clamping direction S to the foot or to the lever-side end face of the shaped body 11; for this, the transverse pin 18 must be located in the first recesses 7a: angular position I of the rotary lever 9 according to FIG. 1.

Die Distanz a, Fig. 5, lässt sich mittels der Lagerbüchse 8 (einmalig) so einstellen, dass bei der Berührung des Schiebers 4 mit dem Fuss des Formkopfes 11 der Querbolzen 18 in der Ausnehmung 7b zu liegen kommt.The distance a, Fig. 5, can be adjusted by means of the bearing bushing 8 (once) so that upon contact of the slide 4 with the foot of the forming head 11 of the transverse pin 18 comes to rest in the recess 7b.

Durch ein Verdrehen des Hebels 9 in die Winkelstellung II, kann der Querbolzen 18 in der Lagerbuchse 8 angreifen und diese nach Art einer grossen Schraube mit Feingewinde in Spannrichtung S drehen. Vgl. Fig. 4 in Verbindung mit Fig. 5.By turning the lever 9 in the angular position II, the transverse pin 18 can engage in the bearing bush 8 and turn them in the manner of a large screw with fine thread in the clamping direction S. See Fig. 4 in conjunction with FIG. 5.

Die Übertragung des Drehmoments erfolgt somit über den Hebel 9, die Welle 6, den Querbolzen 18 auf das Gewinde 8', welches die Drehbewegung in einen Vorschub in Spannrichtung S wandelt und selbstverständlich selbsthemmend ist.The transmission of torque thus takes place via the lever 9, the shaft 6, the transverse pin 18 on the thread 8 ', which converts the rotational movement in a feed in the clamping direction S and, of course, self-locking.

Das Lösen der Schnellspannvorrichtung erfolgt auf dem umgekehrten Weg: Durch Drehen des Hebels 9 in Gegenrichtung löst sich die vom Gewinde 8' erzeugte Vorspannung und lässt den Querbolzen 18 soweit in der Lagerbuchse 8 verdrehen, dass er von der relativen Winkelstellung II in die Stellung I schwenkt.- Jetzt lässt sich der Hebel 9 zurückziehen, bis an die Lagerbuchse 8, so dass der in Fig. 5 eingezeichnete Abstand a zu Null wird.The release of the quick-release device takes place in the opposite way: by turning the lever 9 in the opposite direction, the bias generated by the thread 8 'and the cross pin 18 rotates in the bearing bush 8 so far that he from the relative angular position II in the position I pivots.- Now the lever 9 can be pulled back to the bearing bush 8, so that the distance a drawn in FIG. 5 becomes zero.

Der zum Ausrücken der hebelseitigen Stirnfläche am Formkörper 11 notwendige maximale Abstand a kann durch das anfängliches Eindrehen der Lagerbuchse 8 in das zentrale Gegengewinde in der Führung 3 leicht eingestellt werden, so dass die Bewegungsabläufe auch bei unterschiedlichen Formköpfen auf einfachste Art optimierbar sind.The necessary for disengaging the lever-side end face on the molded body 11 maximum distance a can be easily adjusted by the initial screwing of the bearing bush 8 in the central mating thread in the guide 3, so that the movements are optimized even with different mold heads in the simplest way.

Der Erfindungsgegenstand hat sich als Schnellspannvorrichtung für die in den Zeichnungen dargestellten Formköpfe bewährt und erlaubt die Fertigungskapazität von Rohrmaschinen zu erhöhen, da sich deren Umrüstzeiten beträchtlich reduzieren. Ebenfalls ergibt sich eine verbesserte Flexibilität durch den Erfindungsgegenstand, da die kürzeren Umrüstzeiten auch eine Rohrherstellung "vor Ort" erlauben, wodurch Dispositions- und Transportkosten reduziert werden und die angestrebte "Just in Time" - Fertigung erfolgen kann.The subject invention has proven itself as a quick-release device for the forming heads shown in the drawings and allows to increase the manufacturing capacity of pipe machines, since their changeover times reduce considerably. Also results in an improved flexibility by the subject invention, since the shorter changeover times also allow a pipe production "on site", which disposition and transport costs are reduced and the desired "just in time" - can be made.

Durch Änderungen an der Form des Schiebers 4 lassen sich an Maschinen zur Herstellung und Bearbeitung von Wickelfalzrohren auch andere Maschinenteile, Einrichtungen und Aggregate aufspannen und leicht auswechseln. Ebenfalls können einzelne Funktionselemente der Schnellspannvorrichtung substituiert werden, so beispielsweise zur Kopplung des Schiebers 4 die Sitftschraube 5 und die Ringnut 17 durch eine im Wellende der Welle 6 vorgesehene Nut mit eingesetztem Seegerring. By changing the shape of the slide 4 can be on machines for the production and processing of spiral ducts and other machine parts, facilities and aggregates span and easy to replace. Also, individual functional elements of the quick release device can be substituted, for example, for coupling the slider 4, the seat screw 5 and the annular groove 17 by a provided in the shaft end of the shaft 6 groove with inserted Seeger ring.
