Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Crimpvorrichtung, die ein durch einen Exzenterantrieb aus einer Anfangsposition in eine Crimpposition bewegbares Crimpwerkzeug umfaßt, wobei der Exzenterantrieb durch einen mit einer Steuerung versehenen Motor angetrieben wird, wobei ein Encoder zur Erfassung der Drehungen des Exzenterantriebs vorgesehen ist, der elektrisch leitend mit der Steuerung verbunden ist und wobei an der Steuerung die jeweiligen Anfangs-und die Crimppositionen des Exzenterantriebs eingestellt werden können.The invention relates to a crimping apparatus comprising a crimping tool movable by an eccentric drive from an initial position to a crimping position, the eccentric drive being driven by a motor provided with a control, an encoder for detecting the rotations of the eccentric drive being electrically conductive the controller is connected and wherein the control of the respective initial and the crimping positions of the eccentric drive can be adjusted.

Stand der TechnikState of the art

Eine solche Crimpvorrichtung ist aus der EP 1202404 A1 bekannt. Dabei muss zu einer Inbetriebnahme jeweils die Anfangs- und die Crimpposition gewählt werden, was einiges Überlegen erfordert, um einen definierten Crimphub zu erzielen.Such a crimping device is from the EP 1202404 A1 known. In each case, the start and the crimping position must be selected for commissioning, which requires some consideration in order to achieve a defined crimping stroke.

Aus der EP 0884811A1 ist eine Crimpvorrichtung bekannt, bei der zur Verarbeitung unterschiedlicher Kontakte jeweils die Anfangs- und Endposition des Crimpkontaktes gewählt werden muß und somit unabhängig voneinander festgelegt wird. Dies ist sehr aufwändig.From the EP 0884811A1 a crimping apparatus is known in which the respective starting and end position of the crimp contact must be selected for processing different contacts and thus determined independently of each other. This is very expensive.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zu Grunde, eine Crimpvorrichtung der eingangs genannten Art derart weiter zu entwickeln, dass sich die Anwendung vereinfacht.The invention is based on the object, a crimping apparatus of the type mentioned in such a way that simplifies the application.

Diese Aufgabe wird erfindungsgemäß bei einer Vorrichtung nach dem Oberbegriff durch die kennzeichnenden Merkmale von Anspruch 1 gelöst. Auf vorteilhafte Weiterbildungen nehmen die Unteransprüche Bezug.This object is achieved in a device according to the preamble by the characterizing features of claim 1. In advantageous developments, the dependent claims.

Bei der erfindungsgemäßen Vorrichtung lässt die Steuerung nur eine isolierte Einstellung der Crimpposition zu und die Anfangsposition ist durch einen starr vorgegebenen Bewegungsablauf des Crimpwerkzeugs starr an die jeweilige Crimpposition des Crimpwerkzeugs gekoppelt, wodurch sie nur gemeinsam mit der jeweiligen Crimpposition verstellt werden kann.In the apparatus according to the invention, the control allows only an isolated setting of the crimping position and the initial position is rigidly coupled by a rigidly predetermined movement sequence of the crimping tool to the respective crimping position of the crimping tool, whereby it can only be adjusted together with the respective crimping position.

Dabei geht die Erfindung aus von der Erkenntnis, dass die Anfangsposition des Crimpwerkzeugs in Bezug auf das damit erzielte Crimpergebnis völlig gleichgültig ist und nicht der gesonderten Einstellung bedarf. Sie ist daher bei der erfindungsgemäßen Crimpvorrichtung auch nicht frei wählbar sondern durch den starr vorgegebenen Bewegungsablauf starr an die Crimpposition des Crimpwerkzeugs gekoppelt. Der resultierende Drehwinkel kann starr auf einen Wert A von hinreichender Größe eingestellt sein und bleibt unabhängig von der Größe der jeweiigen Hubbewegung immer in gleicher Größe erhalten. Das Einstellen der Crimpvorrichtung und damit zugleich das Verfarhen zu deren Bedienung wird dadurch stark vereinfacht und die Betriebsbereitschaft schneller als bisher erzielt.The invention is based on the recognition that the initial position of the crimping tool is completely indifferent with respect to the crimping result achieved thereby and does not require the separate adjustment. It is therefore not freely selectable in the crimping apparatus according to the invention but rigidly coupled by the rigid predetermined movement sequence to the Crimppositions. The resulting angle of rotation can be set rigidly to a value A of sufficient size and, regardless of the size of the respective lifting movement, always remains the same size. The setting of the crimping device and thus at the same time the Verfarhen to their operation is greatly simplified and the operational readiness achieved faster than before.

In Abhängigkeit von der Art des gewählten Encoders und der Steuerung lässt sich die Feineinstellbarkeit des Crimpwerkzeuges nahezu beliebig gestalten. Bevorzugt lässt sich die Crimpposition des Crimpwerkzeugs in 1/1000 mm - Schritten verstellen.Depending on the type of the selected encoder and the controller, the fineness of the crimping tool can be made almost arbitrary. Preferably, the crimping position of the crimping tool can be adjusted in 1/1000 mm increments.

Dabei kann es vorgesehen sein, dass die Crimpposition durch Sekundärsignale verstellbar ist, beispielsweise durch Sekundärsignale, die die Betriebstemperatur der Crimpvorrichtung angeben und/oder den Verschleiß des Crimpwerkzeugs. Die Sekundärsignale können dabei ebenso wie die die Crimphöhe angebenden Signale unmittelbar in mm - Angaben umgerechnet werden, beispielsweise auf der Grundlage von Erfahrungswerten, um die Einstellung und eine eventuelle Nachjustierung zu erleichtern. Letztere kann mittels der Steuerung auch automatisch erfolgen.It can be provided that the Crimpposition is adjustable by secondary signals, for example by secondary signals indicating the operating temperature of the crimping and / or the wear of the crimping tool. The secondary signals, as well as the signals indicating the crimp height, can be converted directly into mm data, for example on the basis of empirical values, in order to facilitate the adjustment and a possible readjustment. The latter can also be done automatically by means of the controller.

Nach einer vorteilhaften Ausgestaltung ist zusätzlich zur Feinverstellbarkeit der Crimpposition eine Grobverstellbarkeit für die Crimpposition vorgesehen, die eine Umstellmöglichkeit für ein Crimpwerkzeug mit einem 30 - oder 40 mm - Hub umfasst. Diese beiden Höhen von Crimpwerkzeugen sind durch eine branchenübliche Normung abgedeckt und bei den Kabelkonfektionierern gewöhnlich beide vorhanden. Sie können weiterhin problemlos durch einfaches Umschalten verwendet werden, indem die Crimpposition einfach an den Hub des zur Anwendung gelangenden Werkzeuges angepasst wird.According to an advantageous embodiment, a coarse adjustability for the crimping position is provided in addition to the finely adjustable Crimpposition, which provides a Umstellmöglichkeit for a crimping tool with a 30 - or 40 mm - Hub includes. These two heights of crimping tools are covered by industry-standard standardization and usually both are present in the cable confectioners. They can also be easily used by simply switching by simply adjusting the crimping position to the stroke of the tool being used.

Der starr vorgegebene Bewegungsablauf des Crimpwerkzeugs kann in sich beliebig gestaltet sein, um ein besonders gutes Crimpergebnis zu erzielen und zur Maschinenschonung beispielsweise zumindest eine Beschleunigungs-und/oder Bremsphase umfassen, bedarfsweise aber auch Zonen, in denen das Crimpwerkzeug mit verminderter Geschwindigkeit gefahren wird. Dies trifft vor allem auf die vorwärts gerichtete Bewegung des Crimpwerkzeuges zu. In Bezug auf die rückwärts gerichtete Bewegung kann demgegenüber stets mit der größtmöglichen Geschwindigkeit gefahren werden, die hinreichend werkzeugschonend und präzise ist. Vor- und Rückwärtsbewegung müssen somit nicht mit demselben Geschwindigkeitsprofil gefahren werden.The rigid predetermined sequence of movements of the crimping tool can be designed in any desired to achieve a particularly good Crimpergebnis and to protect the machine, for example, at least one acceleration and / or braking phase, but if necessary, also zones in which the crimping tool is driven at a reduced speed. This applies especially to the forward movement of the crimping tool. In contrast, with respect to the backward movement can always be driven with the highest possible speed, which is sufficiently tool-friendly and accurate. Forward and backward movement thus need not be driven with the same velocity profile.

Da für unterschiedliche Crimpkontakte unterschiedliche Bewegungsabläufe sinnvoll sein können, hat es sich als vorteilhaft bewährt, wenn der optimale Bewegungsablauf des jeweiligen Crimpwerkzeugs auf einem Datenträger gespeichert und mittels des Datenträgers jeweils in die Steuerung eingebbar ist. Ein solcher Datenträger kann dabei durch eine von der Steuerung lesbare Scheckkarte gebildet sein.Since different motion sequences may be useful for different crimp contacts, it has proved to be advantageous if the optimum movement sequence of the respective crimping tool is stored on a data carrier and can be entered into the controller by means of the data carrier. Such a data carrier can be formed by a readable by the controller bank card.

Ausführung der ErfindungEmbodiment of the invention

Die in den Fig. 1 bis 3 schematisch gezeigte Crimpvorrichtung umfasst ein durch einen Exzenterantrieb 1 aus einer Anfangsposition 2 in eine wählbare Crimpposition 3 bewegbares Crimpwerkzeug 4, wobei der Exzenterantrieb 1 durch einen mit einer Steuerung 5 versehenen Motor 6 angetrieben ist und wobei ein Encoder 7 zur Erfassung von Relativverdrehungen des Exzenterantriebs 1 vorgesehen ist, der signalleitend mit der Steuerung 5 verbunden ist. Dabei lässt die Steuerung nur eine isolierte Einstellung der Crimpposition 3 zu, derart, dass die Anfangsposition 2 durch einen starr vorgegebenen Bewegungsablauf des Crimpwerkzeugs 4 starr an die jeweilige Crimpposition 3 des Crimpwerkzeugs gekoppelt ist und nur gemeinsam mit der jeweiligen Crimpposition 3 verstellt werden kann, z.B. in 1/1000 mm - Schritten. Die richtige Crimpposition ist dadurch leicht einstellbar und die Crimpvorrichtung demgemäss besonders schnell in Betrieb nehmbar. Der Motor ist ein Servomotor, der es erlaubt, an einer exakt vorherbestimmten Stelle des Drehwinkels zu stoppen oder anzulaufen.The in the Fig. 1 to 3 The crimping apparatus shown schematically comprises a crimping tool 4 which can be moved by an eccentric drive 1 from an initial position 2 into a selectable crimping position 3, the eccentric drive 1 being driven by a motor 6 provided with a control 5 and an encoder 7 being provided for detecting relative rotations of the eccentric drive 1 is that is signal-conducting connected to the controller 5. The control allows only an isolated setting of the crimping position 3, such that the initial position 2 is rigidly coupled by a rigidly predetermined movement sequence of the crimping tool 4 to the respective crimping position 3 of the crimping tool and can only be adjusted together with the respective crimping position 3, eg in 1/1000 mm increments. As a result, the correct crimping position can be easily adjusted and the crimping device can accordingly be put into operation particularly quickly. The motor is a servomotor that allows it to stop or start at a precisely predetermined position of the rotation angle.

Der in Figur 1 wiedergegebene Bewegungsablauf zeigt eine Anfangsposition 2, die vor dem oberen Totpunkt 8 liegt und ein Crimpposition 3 die vor dem unteren Totpunkt 9 liegt. Der in der Anfangsposition beginnende Arbeitshub H überschreitet somit den oberen Totpunkt 8, was zunächst einmal dazu führt, dass sich das Crimpwerkzeug 3 vom Amboss 10 entfernt statt sich direkt zu diesem hin zu bewegen. Dies ist ohne nennenswerten Nachteil insofern, als die Bewegung lastfrei erfolgt und dazu genutzt werden kann, die maximale Geschwindigkeit sehr schnell zu erreichen und den oberen Totpunkt 8 mit hoher Geschwindigkeit zu überwinden. Dies trifft auch auf den Rückhub in Richtung des dargestellten Pfeils zu.The in FIG. 1 reproduced sequence of movements shows an initial position 2, which is before the top dead center 8 and a crimping position 3 before the bottom dead center 9 is located. The starting in the initial position working stroke H thus exceeds the top dead center 8, which initially leads to the fact that the crimping tool 3 away from the anvil 10 instead of moving directly towards this. This is without any significant disadvantage in that the movement takes place without load and can be used to reach the maximum speed very quickly and to overcome the top dead center 8 at high speed. This also applies to the return stroke in the direction of the arrow shown.

In der gezeigten Crimpposition 3 haben die Crimpwerkzeuge einen Nennabstand S von einander, der es erlaubt, das Crimpwerkzeuge 4 in Abhängigkeit von dem jeweiligen Crimpergebnis noch weiter an den Ambos 10 anzunähern oder in einem etwas größeren Abstand von diesem anhalten zu lassen. Das Crimpergebnis kann beispielsweise durch eine Nachmessung der Auszugkraft festgestellt werden, die erhalten wird, wenn man die Verbindung eines an ein Kabel angecrimpten Kontaktelementes auf Zug belastet. Ist die Auszugkraft zu niedrig, dann erfordert das eine Verminderung des Nennabstandes S, im anderen Fall eine Vergrößerung des Nennabstandes S. Solche Veränderungen werden unmittelbar in die Steuerung eingegeben mit der Folge, dass sich das Crimpwerkzeug 4 entsprechend weiter oder weniger weit nach unten bewegt. Der Winkel A zwischen der Anfangs- und der Crimpposition bleibt dabei stets in gleicher Größe erhalten. Der hierdurch überschriebene Arbeitsbereich der Exenterwelle 12 ist aus Gründen der Anschaulichkeit schraffiert dargestellt.In the crimping position 3 shown, the crimping tools have a nominal distance S from one another, which allows the crimping tool 4 to be further approached or stopped at a slightly greater distance from the anvil 10 as a function of the respective crimping result. The Crimpergebnis can be determined, for example, by a final measurement of the pull-out force, which is obtained when you load the connection of a crimped to a cable contact element to train. If the pull-out force is too low, this requires a reduction of the nominal distance S, in the other case an increase of the nominal distance S. Such changes are entered directly into the control, with the result that the crimping tool 4 moves further downwards or downwards accordingly. The angle A between the initial and the Crimpposition always remains the same size. The work area of the eccentric shaft 12 which is thereby overwritten is hatched for reasons of clarity.

Der in Figur 2 wiedergegebene Bewegungsablauf der Crimpvorrichtung nach Fig. 1 zeigt eine Anfangsposition 2, die hinter dem oberen Totpunkt 8 liegt und ein Crimpposition 3, die ebenfalls vor dem unteren Totpunkt 9 liegt. Der in der Anfangsposition beginnende Arbeitshub H überschreitet somit nicht den oberen Totpunkt 8. Das Crimpwerkzeug 3 wird somit unmittelbar zum Ambos 10 hin bewegt. Im übrigen gilt die vorstehende Beschreibung. Auch bei dieser Einstellung bleibt die Größe des Winkels A zwischen der Anfangs- und der Crimpposition 2, 3 auch beim Nachjustieren stets erhalten.The in FIG. 2 reproduced movement sequence of the crimp after Fig. 1 shows an initial position 2, which is located behind the top dead center 8 and a crimping position 3, which also lies before the bottom dead center 9. The starting in the initial position working stroke H thus does not exceed the top dead center 8. The crimping tool 3 is thus moved directly to the Ambos 10 out. Otherwise, the above description applies. Also with this Setting remains the size of the angle A between the starting and the Crimpposition 2, 3 always maintained during readjustment.

Die Crimpposition 3 des Crimpwerkzeugs kann außerdem durch Sekundärsignale verstellbar ausgebildet sein, die von der Betriebstemperatur und/oder dem Verschleiß des Crimpwerkzeugs generiert sind. Fig. 3 zeigt einen Temperatursensor 11, der zu diesem Zwecke an dem Maschinengestell der Crimpvorrichtung angebracht und signalleitend mit der Steuerung verbunden ist. Die bei einer betriebsbedingten Erwärmung der Crimpvorrichtung eintretenden Dehnungen werden dadurch in der Steuerung berücksichtigt, in dem der Abstand S zwischen dem Crimpwerkzeug und dem Ambos in der Crimpposition wieder auf den optimalen Wert zurückgeführt wird.The crimping position 3 of the crimping tool can also be designed to be adjustable by secondary signals which are generated by the operating temperature and / or the wear of the crimping tool. Fig. 3 shows a temperature sensor 11, which is attached to this purpose on the machine frame of the crimping device and signal conductively connected to the controller. The strains occurring during an operational heating of the crimping device are thereby taken into account in the control, in which the distance S between the crimping tool and the anvil in the crimping position is restored to the optimum value.

Der durch den Winkel A starr vorgegebene Bewegungsablauf des Crimpwerkzeugs 4 ist hinsichtlich der in den einzelnen Teilbereichen angewandten Drehgeschwindigkeiten der Exenterwelle 12 beliebig gestaltbar. Er sollte aber zumindest eine Beschleunigungs- und/oder Bremsphase umfassen, die sich an die Anfangsposition 2 bzw. an die Crimpposition 3 anschließen. Der Bewegungsablauf wird dadurch weicher. Er bietet außerdem den Vorteil, dass die Dauerhaltbarkeit der Crimpvorrichtung verbessert und der Geräuschpegel u.U. erheblich gesenkt wird.The predetermined by the angle A rigid movement sequence of the crimping tool 4 can be designed arbitrarily with respect to the applied in the individual sub-ranges rotational speeds of the eccentric shaft 12. But it should at least include an acceleration and / or braking phase, which follow the initial position 2 and the crimping position 3. The movement becomes softer. It also offers the advantage of improving the durability of the crimping apparatus and the noise level u.U. is lowered considerably.

Für verschiedene Crimpwerkzeuge können unterschiedliche Bewegungsabläufe des Crimpwerkzeugs sinnvoll sein. Demgemäß hat es sich als sinnvoll erwiesen, wenn die jeweils optimalen Bewegungsabläufe der einzelnen Crimpwerkzeuge 4 auf einem Datenträger gespeichert und mittels des Datenträgers in die Steuerung 5 eingebbar sind.For different crimping tools, different movements of the crimping tool may be useful. Accordingly, it has proven to be useful if the respective optimal movement sequences of the individual crimping tools 4 are stored on a data carrier and can be entered into the controller 5 by means of the data carrier.

Ein solcher Datenträger kann durch eine von der Steuerung 5 lesbare Scheckkarte gebildet sein, die einfach zu handhaben und in die Steuerung einführbar ist.Such a data carrier can be formed by a credit card readable by the controller 5, which is easy to handle and can be inserted into the controller.

Das erfindungsgemäße Verfahren zur Einstellung einer Crimpvorrichtung ist besonders einfach zu handhaben. Es läßt sich ohne besonderen Aufwand leicht anwenden auch bei Crimpvorrichtungen, die eine hohe Robustheit haben. Durch die vereinfachte Handhabung ist eine schnellere Umrüstung von Crimpvorrichtungen als bisher möglich. Dennoch bietet das Verfahren den Vorteil einer extrem hohen Arbeitsgenauigkeit in Verbindung mit der Möglichkeit, Nachjustierungen des Crimpwerkzeugs zur Optimierung des Nennabstandes S entweder automatisch oder manuell auf direktem Wege mit Hilfe eines Servomotors durch unmittelbare Einstellung der Steuerung auf digitalem Wege vorzunehmen. Empirisch ermittelte Werte können dabei mit verwendet werden, um ein optimales Crimpergebnis zügig zu erreichen.The method according to the invention for setting a crimping device is particularly easy to handle. It can be easily applied without any special effort even with crimping devices that have a high degree of robustness. Due to the simplified handling a faster conversion of crimping devices than previously possible. Nevertheless, the method offers the advantage of an extremely high working accuracy in connection with the possibility of readjustments of the crimping tool to optimize the nominal distance S either automatically or manually directly by means of a servo motor by directly setting the control digitally. Empirically determined values can be used to quickly achieve the optimum crimping result.
