Description

Die Erfindung betrifft eine Crimpvorrichtung mit einer einen konstanten Arbeitshub hervorrufenden Antriebsvorrichtung, die auf ein Crimpwerkzeug wirkt.The invention relates to a crimping device with a drive device which produces a constant working stroke and which acts on a crimping tool.

In den bekannten Crimpmaschinen, wie z.B. in Exzenterpressen, ist zur Übertragung des Crimphubs zwischen dem oberen und unteren Pleuellager eine biegesteife, verstellbare Pleuelstange angeordnet. Die Pleuelstange wird empirisch auf eine Crimphöhe eingestellt, die zur Erzielung eines optimalen Crimps für eine bestimmte Verbinderkralle und einen bestimmten Leiterquerschnitt erforderlich ist. Beim Wechsel entweder des Leiterquerschnitts oder des Verbinderkrallentyps muß die optimale Crimphöhe des Verbinders erneut durch mechanische Verstellung der Pleuelstange empirisch ermittelt werden, bevor die Produktion wieder aufgenommen werden kann. Dieser Vorgang erfordert sehr viel Zeit und Erfahrung des Bedienungspersonals, weil bei der Crimphöhenveränderung sehr geringe Wege mit hoher Genauigkeit eingestellt werden müssen. Dabei wird Ausschuß in erheblichem Umfange produziert.In the known crimping machines, e.g. in eccentric presses, a rigid, adjustable connecting rod is arranged to transmit the crimp stroke between the upper and lower connecting rod bearings. The connecting rod is set empirically to a crimp height which is necessary to achieve an optimal crimp for a specific connector claw and a specific conductor cross section. When changing either the conductor cross-section or the connector claw type, the optimum crimp height of the connector must be empirically determined again by mechanically adjusting the connecting rod before production can be restarted. This process requires a lot of time and experience of the operating personnel, because very small paths have to be set with high accuracy when changing the crimp height. A considerable amount of waste is produced.

Darüber hinaus sind Crimpmaschinen bekannt, bei denen der Arbeitshub pneumatisch oder hydraulisch erzeugt wird und direkt auf die Crimpwerkzeuge übertragen wird. Über aufwendige Ventilsteuerung wird nach Erreichen einer bestimmten Crimpkraft der Arbeitshub gestoppt und der Rückhub eingeleitet. Dabei wird die erforderliche Crimpkraft nur kurzzeitig aufrechterhalten, was vielfach nicht zur Erzielung eines optimalen Crimps ausreicht. Femer werden derartige Anlagen häufig durch unkontrollierbare Druckstöße beeinträchtigt. Es ist daher nahezu unmöglich, ohne erheblichen Aufwand übliche Crimpmaschinen auf einen optimalen Crimphub einzustellen und dabei ausreichend lange eine vorgewählte Crimpkraft aufrechtzuerhalten.In addition, crimping machines are known in which the working stroke is generated pneumatically or hydraulically and is transferred directly to the crimping tools. After a certain crimping force has been reached, the working stroke is stopped and the return stroke initiated by means of complex valve control. The required crimping force is only maintained for a short time, which is often not enough to achieve an optimal crimp. Systems of this type are also frequently impaired by uncontrollable pressure surges. It is therefore almost impossible to set conventional crimping machines to an optimal crimp stroke without considerable effort and to maintain a preselected crimping force for a sufficiently long time.

Aufgabe der Erfindung ist, eine Vorrichtung zu schaffen, die in fast allen bekannten Crimpmaschinen verwendbar ist und eine konstante vorwählbare Crimpkraft gewährleistet.The object of the invention is to provide a device which can be used in almost all known crimping machines and which ensures a constant preselectable crimping force.

Diese Aufgabe wird durch die Merkmale des Hauptanspruchs gelöst. Weitere erfindungswesentliche Merkmale sind Gegenstand der Unteransprüche 2 bis 8.This object is solved by the features of the main claim. Further features essential to the invention are the subject of dependent claims 2 to 8.

Vorteilhaft ist, daß die Aufrechterhalterung der Crimpkraft durch eine nachgiebige Gegenkraft gewährleistet und der überschüssige Arbeitshub auf das Kniehebelsystem abgelenkt wird, wobei die Gegenkraft geringer als die erforderliche Crimpkraft ist.It is advantageous that the crimping force is maintained by a resilient counterforce and the excess working stroke is deflected onto the toggle lever system, the counterforce being less than the required crimping force.

Anhand der Zeichnung wird die Erfindung beispielhaft näher erläutert. Es zeigen:

  • Fig. 1 eine Vorderansicht des Kniehebelsystems,
  • Fig. 2 einen Schnitt entlang der Linie 11-11 in Fig. 1,
  • Fig. 3 eine Rückansicht des Kniehebelsystems,
  • Fig. 4 einen Schnitt entlang der Linie IV-IV in Fig. 3,
  • Fig. 5 eine Seitenansicht des Kniehebelsystems.
The invention is explained in more detail by way of example with reference to the drawing. Show it:
  • 1 is a front view of the toggle lever system,
  • 2 shows a section along the line 11-11 in FIG. 1,
  • 3 is a rear view of the toggle lever system,
  • 4 shows a section along the line IV-IV in FIG. 3,
  • Fig. 5 is a side view of the toggle lever system.

Zwischen dem Stützlager 1 der Antriebsvorrichtung und dem Stützlager 2 des Crimpwerkzeuges ist das Kniehebelsystem 3 angeordnet, wobei das Stützlager 1 mit dem oberen Pleuellager 4 und das Stützlager 2 z. B. mit dem nicht dargestellten unteren Pleuellager einer Exzenterpresse in beliebiger Weise verbunden ist.The toggle lever system 3 is arranged between the support bearing 1 of the drive device and the support bearing 2 of the crimping tool, the support bearing 1 with the upper connecting rod bearing 4 and the support bearing 2 z. B. is connected to the lower connecting rod bearing, not shown, of an eccentric press in any way.

Das Kniehebelsystem 3 besteht aus einem an den Stützlagern 1 und 2 gelenkig gelagerten Doppelkniehebelsystem 5, das mit einem Federsystem 6 belastet ist.The toggle lever system 3 consists of a double toggle lever system 5 which is articulated on the support bearings 1 and 2 and which is loaded with a spring system 6.

Das Doppelkniehebelsystem 5 ist symmetrisch aus zwei Kniehebeln 7 aufgebaut. Jeder Kniehebel 7 weist einen im Stützlager 1 um die Achse 10 drehbar gelagerten oberen freien Arm 8 und einen im Stützlager 2 um die Achse 11 drehbar gelagerten unteren Arm 9 auf. Miteinander sind die Hebelarme 8 und 9 drehbar um die Kniegelenkbolzen 12 verbunden. Sie stützen sich gegeneinander über die von den Bolzen 12 ausgehenden Anschlagstege 13 ab, die einen Anschlag bilden. Die Länge der Stege 13 ist derart gewählt, daß die Kniehebel 7 in der Vorderansicht nach außen abgewinkelt sind und die Hebelarme 8 und 9 einen Winkel α von 140 bis 160 Grad, vorzugsweise von 148 bis 152 Grad, bilden.The double toggle lever system 5 is constructed symmetrically from two toggle levers 7. Each toggle lever 7 has an upper free arm 8 which is rotatably mounted about the axis 10 in the support bearing 1 and a lower arm 9 which is rotatably mounted about the axis 11 in the support bearing 2. The lever arms 8 and 9 are rotatably connected to one another about the knee joint bolts 12. They are supported against each other via the stop webs 13 that extend from the bolts 12 and that form a stop. The length of the webs 13 is selected such that the toggle levers 7 are angled outwards in the front view and the lever arms 8 and 9 form an angle α of 140 to 160 degrees, preferably of 148 to 152 degrees.

Nach dem dargestellten bevorzugten Beispiel bestehen die oberen Hebelarme 8 aus je einem Winkeleisen, die im Schlitz 14 des Stützlagers 1 in den Achsen 10 und im Bereich der Winkelecke mit den Bolzen 12 in den Achsgabeln 15 des Hebelarmes 9 lagern. An die Achsgabel 15 schließt sich der untere Teil 16 des Hebelarmes 9 an, der im Schlitz 17 des Stützlagers 2 mit der Achse 11 lagert.According to the preferred example shown, the upper lever arms 8 each consist of an angle iron, which is mounted in the slot 14 of the support bearing 1 in the axes 10 and in the area of the corner corner with the bolts 12 in the axle forks 15 of the lever arm 9. The lower part 16 of the lever arm 9 adjoins the axle fork 15 and bears in the slot 17 of the support bearing 2 with the axle 11.

Um zu verhindern, daß das Stützlager 1 gegenüber dem Stützlager 2 bei einer Hubbewegung unter Einwirkung der Crimpkraft seitlich ausweicht, ist eine Längsführung vorgesehen. Diese besteht aus dem Führungsstück 18, das fest an der Rückwand 19 des Stützlagers 1 angeordnet ist und sich senkrecht nach unten erstreckt. Es wird mit seinem Gleitstück 22 in einer entsprechend ausgebildeten Führungsnut 20 der Rückwand 21 des Stützlagers 2 geführt, wobei in Ausgangsstellung der erfindungsgemäßen Vorrichtung ein Gleitspalt 23 zwischen dem Ende des Gleitstückes 22 und dem Boden 24 der Nut 20 verbleibt, dessen Höhe den Maximalhub der Vorrichtung begrenzt.In order to prevent the support bearing 1 from laterally evading the support bearing 2 during a lifting movement under the influence of the crimping force, a longitudinal guide is provided. This consists of the guide piece 18, which is fixedly arranged on the rear wall 19 of the support bearing 1 and extends vertically downwards. It is guided with its slider 22 in a correspondingly designed guide groove 20 of the rear wall 21 of the support bearing 2, a sliding gap 23 remaining between the end of the slider 22 and the bottom 24 of the groove 20 in the starting position of the device according to the invention, the height of which is the maximum stroke of the device limited.

Das Doppelkniehebelsystem 5 wird erfindungsgemäß mit einer auf die Kniehebel 7 im Sinne des Andrückens des Anschlags wirkende nachgiebige Kraft belastet. Vorzugsweise wirkt diese Kraft rechtwinklig zur Crimpkraft auf jeden Kniehebel 7 in Richtung der Abstützstege 13. Im dargestellten Beispiel wird die Gegenkraft mit einem Federsystem 6 erzeugt. Selbstverständlich ist es aber auch möglich, die Gegenkraft z. B. vorzugsweise pneumatisch oder auf eine andere geeignete Weise zu erzeugen.According to the invention, the double toggle lever system 5 is applied to the toggle lever 7 in the sense of pressing the stop acting resilient force. This force preferably acts at right angles to the crimping force on each toggle lever 7 in the direction of the support webs 13. In the example shown, the counterforce is generated with a spring system 6. Of course, it is also possible to use the counterforce z. B. preferably pneumatically or in another suitable way.

Das Federsystem 6 besteht aus einer durchgehenden, waagerecht angeordneten Zugstange 25, die in Querbohrungen der auf den Bolzen 12 fest sitzenden Achslager 26 gleitend lagert und zwischen den Lagern 26 und der Verstellvorrichtung 27 die Druckfedern 28 trägt, die sich gegen die Verstellvorrichtung 27 und das Achslager 26 in geeigneter Weise abstützen. Mit der Verstellvorrichtung 27 kann die Federkraft sehr genau eingestellt werden.The spring system 6 consists of a continuous, horizontally arranged tie rod 25, which slides in transverse bores of the axle bearings 26 firmly seated on the bolts 12 and carries the compression springs 28 between the bearings 26 and the adjusting device 27, which springs against the adjusting device 27 and the axle bearing Support 26 in a suitable manner. The spring force can be set very precisely with the adjusting device 27.

Die Funktionsweise der neuen Vorrichtung ist folgende. Die zum Crimpen erforderliche und von z.B. einer Exzenterpresse erzeugte Crimpkraft wird über das enfndungsgemäße Kniehebelsystem auf die Crimpwerkzeuge übertragen. Beim Erreichen einer vorgewählten bestimmten Crimpkraft knickt bei weiterer Belastung das Kniehebelsystem gegen die nachgiebige Kraft aus. Dadurch wird mit Sicherheit erreicht, daß die an den Crimpwerkzeugen auftretende Crimpkraft kontrollierbar eine bestimmte Höhe nicht übersteigt. Soll die Vorrichtung auf eine andere Verbinderkralle und/oder einen anderen Verbinder umgestellt werden, wird die nachgiebige Kraft des Federsystems verstellt. Die neue Einstellung gewährleistet dann die gewünschte neue Crimpkraft.The operation of the new device is as follows. The required for crimping and e.g. Crimping force generated by an eccentric press is transmitted to the crimping tools via the inventive toggle lever system. When a preselected specific crimping force is reached, the toggle lever system buckles against the resilient force under further load. This ensures with certainty that the crimping force occurring on the crimping tools does not controllably exceed a certain height. If the device is to be switched to a different connector claw and / or a different connector, the resilient force of the spring system is adjusted. The new setting then ensures the desired new crimping force.

Bei der erfindungsgemäßen Vorrichtung sind die Federkennlinien, der Kniehebelwinkel α und die Spalthöhe des Spalts 23 derart aufeinander abgestimmt, daß die Einstellung der Crimpkraft mit großer Genauigkeit vorgenommen werden kann. Die Federkennlinie und der Kniehebelwinkel α korrespondieren dabei so, daß in einem weiten Überlastbereich die Crimpkraft annähernd gleich bleibt. Mit der Einstellung einer bestimmten Crimpkraft ergibt sich für jede Einheit, bestehend aus Verbinderkralle und dem der Verbinderkralle zugeordneten Leiterquerschnittsbereich, eine optimale Crimphöhe für alle Einheiten des gleichen Typs. Die Crimphöhendifferenz eines bestimmten Verbindertyps liegt dabei im Rahmen der Spalthöhe des Spalts 23 und beträgt meist nur wenige Zehntel Millimeter. In diesem Bereich sind die Crimpkraftdifferenzen von nur etwa 5 bis 10% der Crimpkraft genau einzustellen, um bei jedem Einheitentyp, bestehend aus Verbinderkralle und Leiter, mit optimaler Kraft crimpen zu können. Dies gelingt in überraschender Weise durch die Kombination des Kniehebelsystems mit der nachgiebigen Kraft dergestalt, daß bei zweckmäßiger Abstimmung des Winkels a des Kniehebelsystems auf die vergleichsweise geringen Federkräfte des Federsystems und bei einer relativ hohen Crimpkraft für jeden Maschinentyp eine erfindungsgemäße Vorrichtung zur Verfügung gestellt werden kann. Da die Bauhöhe der erfindungsgemäßen Vorrichtung lediglich der Bauhöhe der bekannten Pleuelstange entsprechen kann, kann letztere durch die neue Vorrichtung in jeder vorhandenen Exzenterpresse ausgetauscht werden.In the device according to the invention, the spring characteristics, the toggle angle α and the gap height of the gap 23 are coordinated with one another in such a way that the crimping force can be set with great accuracy. The spring characteristic and the toggle angle α correspond so that the crimping force remains approximately the same in a wide overload range. With the setting of a specific crimping force, an optimal crimp height for all units of the same type results for each unit, consisting of connector claw and the conductor cross-sectional area assigned to the connector claw. The crimp height difference of a particular connector type is within the gap height of the gap 23 and is usually only a few tenths of a millimeter. In this area, the crimping force differences of only about 5 to 10% of the crimping force have to be set precisely in order to be able to crimp with optimum force for each unit type, consisting of connector claw and conductor. This is achieved surprisingly by the combination of the toggle lever system with the resilient force such that when the angle a of the toggle lever system is appropriately matched to the comparatively low spring forces of the spring system and with a relatively high crimping force, a device according to the invention can be made available for each type of machine. Since the height of the device according to the invention can only correspond to the height of the known connecting rod, the latter can be replaced by the new device in any existing eccentric press.

In Rahmen der Erfindung wird somit eine Art Überlastsicherung geschaffen, die die Voreinstellung einer Maximallast ermöglicht und beim Überschreiten dieser Last dafür sorgt, daß ein Gegenkraftsystem die Überlast kompensiert. Dies kann - wie beschrieben - mit einem Kniehebel- und Federsystem erfolgen. Statt der Federn sind jedoch auch andere äquivalente Mittel anwendbar, wobei es darauf ankommt, daß die erforderliche Crimpkraftdifferenz mit geeigneten Mitteln auf einstellbare Gegenkraftdifferenzwerte transformiert wird.Within the scope of the invention, a type of overload protection is thus created which enables a maximum load to be preset and, when this load is exceeded, ensures that a counterforce system compensates for the overload. As described, this can be done with a toggle lever and spring system. Instead of the springs, however, other equivalent means can also be used, it being important that the required crimping force difference is transformed with suitable means to adjustable counterforce difference values.
