Description
Die Erfindung betrifft eine Maschine zum beiderseitigen Bördeln und Einziehen zylindrischer Dosenrümpfe gemäß dem Gattungsbegriff des Anspruches 1.The invention relates to a machine for flanging and pulling cylindrical can bodies on both sides according to the preamble of
Es sind vorgenannte Maschinen bekannt (Prospekt Lanico "Bördel- und Einziehautomat BEA 6-325"), welche als Vollautomaten ausgebildet sind und bei denen die Dosenrümpfe die Maschine in horizontaler Lage durchlaufen. Dabei sind mehrere planetenartig kreisende Stationen mit den im Gattungsbegriff genannten Bördel- und Einziehköpfen sowie zugeordneten Schwenkarmen und Steuerkurven vorgesehen.The aforementioned machines are known (prospectus Lanico "automatic flanging and drawing-in machine BEA 6-325"), which are designed as fully automatic machines and in which the can bodies pass through the machine in a horizontal position. There are several planet-like orbiting stations with the crimping and retracting heads mentioned in the generic term, as well as assigned swivel arms and control cams.
Derartige Maschinen haben sich in der Praxis außerordentlich bewährt für die Bearbeitung von zylindrischen Dosenrümpfen mit geschweißter Längsnaht, wie sie insbesondere für Aerosol- oder Getränkedosen verwendet werden.Such machines have proven extremely useful in practice for processing cylindrical can bodies with welded longitudinal seams, as are used in particular for aerosol or beverage cans.
Die bekannten Maschinen sind nur zur Bearbeitung von Blechen geeignet, die eine hinreichende Elastizität aufweisen. Bei Dosenrümpfen aus Blechen größerer Härte bzw. aus doppeltreduzierten Blechen läßt sich der Bördel- und Einziehvorgang nicht in einem Arbeitsgang vollziehen. Selbst bei Anwendung mehrerer Arbeitsgänge neigen derartige Bleche zu Rißbildungen bei ihrer Deformierung. Andererseits besteht ein erhebliches Interesse daran, harte bzw. doppeltreduzierte Bleche bearbeiten zu können, da diese wesentlich preisgünstiger herstellbar sind und Dosenrümpfe aus wesentlich dünnerwandigen Blechen als nach herkömmlicher Art gefertigt werden können.The known machines are only suitable for processing metal sheets that have sufficient elasticity. In the case of can bodies made of sheet metal of greater hardness or of double-reduced sheet metal, the flaring and drawing-in process cannot be carried out in one operation. Even when using multiple operations, such sheets tend to crack when deformed. On the other hand, there is considerable interest in being able to process hard or double-reduced sheets, since these can be produced much more cheaply and can hulls can be made from much thinner-walled sheets than in the conventional way.
Der Erfindung liegt die Aufgabe zugrunde, eine Maschine der einleitend genannten Art so weiterzubilden, daß diese sowohl für die Bearbeitung relativ weicher als auch harter Bleche geeignet ist.The invention has for its object to develop a machine of the type mentioned in the introduction so that it is suitable both for processing relatively soft and hard sheets.
Zur Lösung vorstehender Aufgabe kennzeichnet sich die genannte Maschine dadurch, daß zur Verformung von Dosenrümpfen aus doppeltreduziertem Blech oder anderem Blech mit einer Rockwellhärte von mindestens 60 HR30T jeder Taumelscheibe zwei gemeinsam an dem freien Ende des Schwenkarmes auf parallelen Achsen angeordnete Bördel- und Einziehrollen zugeordnet sind, daß die Rollen jeweils gleichzeitig an den zu behandelnden Dosenrumpf angreifen und diesen in dessen Rotationsrichtung gesehen graduell zunehmend verformen, wobei wenigstens eine der Rollen in bezug auf die andere Rolle und gegen die Taumelscheibe verstellbar gehalten ist.To solve the above problem, the above-mentioned machine is characterized in that for the shaping of can bodies made of double-reduced sheet metal or other sheet metal with a Rockwell hardness of at least 60 HR30T, each swashplate is assigned two flanging and pull-in rollers arranged together on the free end of the swivel arm on parallel axes, that the rollers attack the can body to be treated at the same time and gradually deform it in the direction of rotation thereof, at least one of the rollers with respect to the other role and is held adjustable against the swash plate.
Es wurde festgestellt, daß bei vorgenannter Ausbildung der Maschine durch die Vor- bzw. Nachverformung des jeweiligen Randes des Dosenrumpfes mittels der gleichzeitig auf den Dosenrumpf einwirkenden Bördelund Einziehrollen Dosenrümpfe aus den genannten Blechen innerhalb von Bearbeitungszeiten bearbeitet werden können, wie sie auch für weichere Bleche notwendig sind, ohne daß jedoch bei den harten bzw. doppelt-reduzierten Blechen Rißbildungen in Erscheinung traten. Dadurch daß die jeder Taumelscheibe zugeordneten beiden Bördel- und Einziehrollen gemeinsam an dem freien Ende des Schwenkhebels angeordnet sind und wenigstens eine der Rollen in bezug auf die andere Rolle in und gegen die Taumelscheibe verstellbar gehalten ist, wird die von der einen Rolle bewirkte Vorverformung des Dosenrandes bereits nach kurzem Weg durch die Einwirkung der zweiten Rolle nachverformt, wobei durch die verstellbare Halterung der Rollen zueinander der Grad zwischen der jeweiligen Vor- und Nachverformung während einer jeden Drehung des Dosenrumpfes eingestellt werden kann.It was found that with the above-mentioned design of the machine, pre-shaping or post-shaping of the respective edge of the can body by means of the flanging and pulling-in rollers acting simultaneously on the can body can be processed within processing times, as is also necessary for softer sheets are, but without the hard or double-reduced sheets cracking appeared. Characterized in that the two flaring and retracting rollers assigned to each swash plate are arranged together at the free end of the pivoting lever and at least one of the rolls is held adjustable in and against the swash plate with respect to one another, the pre-deformation of the can rim caused by one roll becomes reshaped after only a short distance by the action of the second roller, the degree between the respective pre- and post-deformation during each rotation of the can body being adjustable by means of the adjustable holding of the rollers relative to one another.
Als besonders günstig hat es sich erwiesen, wenn die am freien Ende des Schwenkarmes weiter außen angeordnete Rolle um die Drehachse der anderen Rolle schwenkbar in dem Schwenkarm gehalten ist. Auf diese Weise kann eine feinfühlige Verstellung der einen Rolle gegenüber der anderen vorgenommen werden.It has proven to be particularly favorable if the roller which is arranged further outward at the free end of the swivel arm is held in the swivel arm so as to be pivotable about the axis of rotation of the other roller. In this way, a sensitive adjustment of the one roller relative to the other can be carried out.
Bei praktischen Versuchen hat es sich erwiesen, daß es besonders vorteilhaft ist, wenn die am freien Ende des Schwenkarmes weiter außen angeordnete Rolle im Durchmesser kleiner als die andere Rolle ausgebildet ist.In practical tests, it has been found that it is particularly advantageous if the diameter of the roller located further outside at the free end of the swivel arm is smaller than the other roller.
Eine weitere zweckmäßige Ausgestaltung ergibt sich dadurch, daß die am freien Ende des Schwenkarmes weiter außen angeordnete Rolle wenigstens in dem Umfangsbereich, mit dem sie in den Dosenrumpf eingreift, schmaler als die andere Rolle ausgebildet ist.A further expedient embodiment results from the fact that the roller, which is arranged further outward at the free end of the swivel arm, is narrower than the other roller, at least in the peripheral region with which it engages in the can body.
Durch die im Durchmesser kleinere und/oder schmalere Rolle am freien Ende des Schwenkarmes erfolgt eine Verformung des Rumpfrandes, ehe dieser nachfolgend der Einwirkung der größeren Rolle ausgesetzt wird. Dabei erfolgt eine Rückfederung des Rumpfmaterials nach der Verformung durch die erste Rolle, die jedoch durch die zweite Rolle weitgehend kompensiert wird.Due to the smaller and / or narrower roller in diameter at the free end of the swivel arm, the fuselage rim is deformed before it is subsequently exposed to the larger roller. The hull material springs back after being deformed by the first roller, but is largely compensated for by the second roller.

Die in den Figuren 1 bis 3 wiedergegebenen Maschinen bestehen aus zwei Antriebsaggregaten 1 und 2, die auf einem Untergestell gehalten sind und über eine Gleichlaufeinrichtung so gesteuert werden, daß sie gemeinsam die zentrische Welle 3 antreiben. Auf der zentrischen Welle 3 sind zwei im Abstand gehaltene Führungsscheiben 4 vorgesehen, zwischen denen die Dosenrümpfe Aufnahme finden. Die Führungsscheiben 4 weisen Ausnehmungen für die in den Figuren 1 bis 3 im einzelnen nicht wiedergegebenen Werkzeuge zum Einziehen und Bördeln der Enden der Dosenrümpfe auf.The machines shown in Figures 1 to 3 consist of two
Die in den Figuren 1 und 2 wiedergegebene Maschine ist gemäß Fig. 3 mit sechs planetenartig kreisenden Stationen 5 ausgerüstet, denen die Dosenrümpfe 7 über eine Zuführrinne 6 zugeleitet werden. Für den Fall einer Unterbrechung der Zufuhr der Dosen 7 durch die Rinne 6 ist eine zusätzliche Zuführrinne 6ʹ vorgesehen, um nach Möglichkeit die kontinuierliche Arbeitsweise der dargestellten Maschine zu gewährleisten.The machine shown in FIGS. 1 and 2 is equipped according to FIG. 3 with six
Während der kreisenden Bewegung der Stationen 5 erfolgt die Bearbeitung der Dosenrümpfe, die nach Fertigstellung mittels eines Abweisers 10 in einen Ausfallschacht 11 überführt werden, von dem sie in nicht dargestellter Weise abtransportiert werden können.During the circular movement of the

Aus den Figuren 4 bis 6 erkennt man, daß in den einzelnen Stationen 5 die Dosenrümpfe 7 von gegensinnig axial einschiebbaren Bördel- und Einziehköpfen 8 und 9 gehalten sind. In der Fig.5 ist nur eines der Aggregate 1 bzw. 2 in teilweisem Schnitt wiedergegeben, da das andere Antriebsaggregat mit in diesem gehaltenen Werkzeugen den gleichen Aufbau wie das in Fig. 5 wiedergegebene Aggregat aufweist.It can be seen from FIGS. 4 to 6 that in the
Man erkennt aus den Figuren 5 und 6, daß der Bördel-und Einziehkopf 9 mit einer rotierend antreibbaren Spindel 11 verbunden ist. Die Spindel 11 ist ihrerseits in einer Schubhülse 12 gehalten bzw. gelagert. Mit der Schubhülse 12 sind drehsicher Vorschubrollen 13 verbunden, die in einer Nut 14 eines ortsfest in dem Gehäuse 15 gehaltenen Ringteiles 16 eingreifen. Ferner ist eine mit der Schubhülse 12 verbundene Führungsrolle 17 fest verbunden, die ihrerseits auf einer mit der zentrischen Welle 3 umlaufenden Führungsbahn 18 zusammenwirkt.It can be seen from FIGS. 5 and 6 that the flanging and drawing-in
Die Schubhülse 12 ist in einem mit der zentrischen Welle 3 verbundenen ringförmigen Lagerteil 19 gehalten.The
Der Aufbau des Bördel- und Einziehkopfes 9 ist in der vergrößerten Darstellung der Fig. 6 im einzelnen wiedergegeben.The structure of the flanging and retracting
Man erkennt, daß auf der Spindel 11 an ihrem freien Ende eine mit der Bördel- bzw. Einziehrolle zusammenwirkende Gegenscheibe 20 drehsicher befestigt ist. Auf der Gegenscheibe 20 stützt sich eine Taumelscheibe 21 ab, welche mit geringem Spiel zwischen der Gegenscheibe 20 und einer mit der Spindel 11 mitrotierenden Hülse 22 gehalten ist. Die Taumelscheibe 21 wirkt mit einem gegen eine Feder 23 axial auf der Spindel 11 verschiebbar gehaltenen Konusteil 24 zusammen. Auf der Hülse 22 ist ferner eine Widerlagerglocke 25 in Form eines Ringbauelementes gehalten.It can be seen that on the
Während des Bördelvorganges wird das jeweilige Ende des Dosenrumpfes 7 durch die noch zu beschreibende Bördelrolle gegen die Taumelscheibe 21 gedrückt und verformt, wobei die Öffnungskante des Dosenrumpfes mit der Widerlagerglocke 25 zusammenwirkt, die den frei zwischen den beiden Bördel- und Einziehköpfen 8 und 9 gehaltenen Dosenrumpf in seiner Lage stabilisiert. Die Taumelscheibe 21 wird unter der Einwirkung der Bördelrolle radial verschoben und bewirkt ihrerseits eine axiale Verschiebung des unter dem Druck der Feder 23 stehenden Konusteils 24. Die Verschiebung der Taumelscheibe 21 erfolgt dabei so weit, daß in dem Bereich zwischen der Gegenscheibe 20 und der Hülse 22 der eingezogene Bördelrand entsteht. Bei Rückbewegung der Bördelrolle wird die Taumelscheibe 21 durch die Wirkung der Feder 23 und das Konusteil 24 wieder in die in Fig. 6 wiedergegebene Stellung überführt, ehe die Freigabe des auf diese Weise gebördelten Dosenrumpfes 7 erfolgt.During the flanging process, the respective end of the
Jedem Bördel- und Einziehkopf 8 bzw. 9 ist ein in dem ringförmigen Lagerteil 19 gehaltener Schwenkarm 26 zugeordnet, welcher drehsicher mit einer Schwenkachse 27 verbindbar ist, die ihrerseits über einen Auslegerarm 28 und an diesem drehbar gehaltenen Kurvenrollen 29 und 30 mit einer Steuerkurve 31 zusammenwirkt. Die Steuerkurve 31 ist drehsicher in dem ringförmigen Bauteil 16 gehalten.Each crimping and retracting
An dem freien Ende des Schwenkarmes 26 sind erfindungsgemäß zwei auf parallelen Achsen angeordnete Bördel- und Einziehrollen 32 und 33 vorgesehen. Dabei ist die Bördel- und Einziehrolle 33 gegenüber der Bördel- und Einziehrolle 32 verschwenkbar gehalten. Zu diesem Zweck ist die Bördel- und Einziehrolle 33 in einem Auslegerarm 34 gelagert, der seinerseits gelenkig, jedoch in jeder Winkelposition feststellbar mit dem Schwenkarm 26 verbunden ist.At the free end of the
Besonders deutlich geht aus der Fig. 5 der parallele Verlauf der Drehachsen 32a und 33a der Bördel- und Einziehrollen hervor. Fig. 5 läßt auch die Feststellschraube 35 für den Auslegerarm 34 erkennen.5 shows the parallel course of the axes of
Die an dem Schwenkarm 26 weiter außen angeordnete Rolle 33 ist in dem Ausführungsbeispiel im Durchmesser kleiner gehalten als die Rolle 32. Sie weist außerdem gegenüber der Rolle 32 eine geringere Dicke auf.The
Aus der Fig. 4 erkennt man, daß die Rollen 32 und 33 gleichzeitig an dem jeweiligen Dosenrumpf 7 angreifen, und daß bei der eingezeichneten Rotationsbewegung des Dosenrumpfes 7 in Bewegungsrichtung des Dosenrumpfes 7 zunächst die schmalere und kleinere Rolle 33 und dann die im Durchmesser größere und auch breiter ausgebildete Rolle 32 in den Dosenrumpf eingreift.From Fig. 4 it can be seen that the
Die für eine Station beschriebene Ausgestaltung der Bördel- und Einziehköpfe 8 und 9 mit zugehörigen Betätigungseinrichtungen und die damit zusammenwirkenden Bördel- und Einziehrollen 32 und 33 mit dem zugeordneten Schwenkarm 26 sind in allen Stationen der wiedergegebenen Maschine identisch ausgebildet.The configuration of the flanging and retracting
Mit derartigen Bördeleinrichtungen ist es erstmalig möglich, in einem Arbeitsgang Dosenrümpfe aus doppeltreduziertem Blech oder anderem Blech mit einer Rockwellhärte von 60 HR 30T und härter zu bearbeiten, um die Ränder der Dosenrümpfe einzuziehen und zu bördeln, ohne daß dabei Rißbildungen zu befürchten sind.It is the first time with such flanging devices It is possible to machine can bodies made of double-reduced sheet metal or other sheet metal with a Rockwell hardness of 60 HR 30T and harder in order to retract and flare the edges of the can bodies without fear of crack formation.
Statt des die Bördel- und Einziehrollen tragenden Schwenkarmes kann auch eine andere die genannten Rollen in der beschriebenen Weise in Richtung zur Taumelscheibe bewegende Zustellvorrichtung vorgesehen sein.Instead of the swivel arm carrying the flanging and retracting rollers, another delivery device moving the aforementioned rollers in the manner described in the direction of the swash plate can also be provided.
