Description

Die Erfindung betrifft eine Crimppresse zur Herstellung einer Crimpverbindung mittels eines antreibbaren Crimpwerkzeuges, das ein Leiterende eines Kabels mit einem Crimpkontakt verbindet.The invention relates to a crimping press for producing a crimp connection by means of a drivable crimping tool, which connects a conductor end of a cable with a crimp contact.

Aus der Patentschrift US 5 966 806 ist eine Einrichtung zur Herstellung einer Crimpverbindung bekannt geworden. Ein Motor treibt eine Exzenterwelle an, die einen Schlitten mit Crimpwerkzeugen auf und ab bewegt. Ein mittels der Motorwelle angetriebener Encoder dient der Positionsbestimmung des Crimpwerkzeuges. Der mit einem Leiterende zu verbindende Crimpkontakt liegt auf einem feststehenden Amboss, wobei Fahnen des Crimpkontaktes bei der Abbewegung des Crimpwerkzeuges plastisch deformiert werden und die Verbindung zum Leiter herstellen. Die Lage des Crimpwerkzeuges im Crimpbereich wird mittels eines Höhensensors gemessen, wobei das Sensorsignal unabhängig vom Encodersignal verwendet wird.US Pat. No. 5,966,806 has disclosed a device for producing a crimp connection. A motor drives an eccentric shaft that moves a carriage up and down with crimping tools. An encoder driven by the motor shaft serves to determine the position of the crimping tool. The crimp contact to be connected to a conductor end rests on a stationary anvil, wherein vanes of the crimp contact are plastically deformed during the movement of the crimping tool and establish the connection to the conductor. The position of the crimping tool in the crimping area is measured by means of a height sensor, the sensor signal being used independently of the encoder signal.

Nachteilig bei dieser bekannten Einrichtung ist, dass bedingt durch den Werkzeugwechsel beim Verarbeiten von unterschiedlichen Crimpkontakten die Crimppresse für längere Zeit stillsteht. Die Crimppresse insbesondere das Crimpwerkzeug muss für den neu zu verarbeitenden Crimpkontakt eingerichtet werden. Ausserdem muss die Rolle und das Band mit den gegurteten Crimpkontakten gewechselt und neu aufgezogen werden.A disadvantage of this known device is that due to the tool change during processing of different crimp contacts the crimping press stands still for a long time. The crimping press, in particular the crimping tool, must be set up for the new crimp contact to be processed. In addition, the role and the band with the strapped crimp contacts must be changed and rewired.

Aus der Patentschrift EP 711 010 B1 ist eine Crimpeinrichtung bekannt geworden, bei der mehrere auf einem verschiebbaren Tisch nebeneinander angeordnete Crimpwerkzeuge vorgesehen sind. Der Tisch wird soweit verfahren, bis das gewünschte Crimpwerkzeug unter eine feststehende Antriebseinheit zu stehen kommt und mittels dieser zur Herstellung von Crimpverbindungen betreibbar ist. Im Gesamten können der Anzahl der Crimpwerkzeuge entsprechende unterschiedliche Crimpkontakte verarbeitet werden, wobei diese Art von Crimpeinrichtung mehrheitlich für die Herstellung von Kabelbäumen verwendet wird.From the patent EP 711 010 B1 a crimping device has become known in which a plurality of crimping tools arranged side by side on a displaceable table are provided. The table is moved so far until the desired crimping tool comes to stand under a fixed drive unit and by means of this for the production of crimps is operable. Overall, the number of different crimp contacts corresponding to the number of crimping tools can be processed, this type of crimping apparatus being used in the majority for the manufacture of wire harnesses.

Nachteilig bei dieser Einrichtung ist, dass beim Wechsel der Kontaktrollen oder der Crimpwerkzeuge die Anlage angehalten und teilweise demontiert werden muss.A disadvantage of this device is that when changing the contact rollers or crimping tools, the system must be stopped and partially dismantled.

Mit der Schrift US 5 913 934 ist eine Crimppresse zur Herstellung von Crimpverbindungen bekannt geworden, wobei Crimpkontakte mit Leiterenden verbunden werden. Ein Exzenterantrieb versetzt ein Crimpwerkzeug in eine lineare Auf-/Abbewegung, wobei der Crimpkontakt mittels Crimpstempel und Amboss mit dem Leiterende verbindbar ist. Das Crimpwerkzeug ist als drehbare Trommel aufgebaut, wobei an der Trommel mehrere Crimpstempel und den Crimpstempeln zugeordnete Ambosse angeordnet sind. Je nach zu verarbeitendem Crimpkontakt kann die Trommel soweit gedreht werden, bis der auf den Crimpkontakt passende Crimpstempel und Amboss in Arbeitsposition sind.The document US Pat. No. 5,913,934 discloses a crimping press for producing crimp connections, with crimp contacts being connected to conductor ends. An eccentric drive puts a crimping tool in a linear up / down movement, wherein the crimp contact is connectable by means of crimping die and anvil to the conductor end. The crimping tool is constructed as a rotatable drum, wherein on the drum a plurality of crimping dies and the crimping dies associated anvils are arranged. Depending on the crimp contact to be processed, the drum can be rotated until the crimping die and anvil matching the crimp contact are in working position.

Nachteilig bei dieser Einrichtung ist, dass nicht nur der die Crimpverbindung herstellende Crimpstempel auf- und abbewegt wird, sondern auch alle übrigen Crimpstempel mitbewegt werden.The disadvantage of this device is that not only the crimping die producing crimping is moved up and down, but also all other crimping dies are moved along.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in Anspruch 1 gekennzeichnet ist, löst die Aufgabe, die Nachteile der bekannten Einrichtung zu vermeiden und eine Einrichtung zu schaffen, bei der beim Übergang von unterschiedlichen Crimpkontakten keine durch Umrüstarbeiten bedingte Stillstandszeiten der Crimppresse entstehen.The invention aims to remedy this situation. The invention, as characterized in claim 1, solves the problem of avoiding the disadvantages of the known device and to provide a device in which caused by retooling no downtime of the crimping press in the transition from different crimp contacts.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass beim Verarbeiten von unterschiedlichen Crimpkontakten die Werkzeuge und die gegurteten Crimpkontakte im voraus eingerichtet werden können. Die Umrüstarbeiten werden ausserhalb der Crimppresse ausgeführt. Die Produktivität der Crimppresse kann dadurch wesentlich erhöht werden, insbesondere dann, wenn kleine Chargen der gleichen Crimpkontakte verarbeitet werden. Die erfindungsgemässe Einrichtung bietet die Möglichkeit, mit minimalen Stillstandszeiten mehrere unterschiedliche Kontaktarten nacheinander zu fahren. Bei grossen Chargen der gleichen Kontaktart kann am Ende des Kontaktvorrates rasch auf einen neuen Kontaktvorrat gewechselt werden.The advantages achieved by the invention are essentially to be seen in the fact that when processing different crimp contacts the tools and the strapped crimp contacts can be set up in advance. The conversion work is carried out outside the crimping press. The productivity of the crimping press can thereby be substantially increased, especially when small batches of the same crimp contacts are processed. The inventive device offers the possibility, with minimal downtime several different Drive contact types one after the other. For large batches of the same type of contact can be quickly changed to a new contact stock at the end of the contact stock.
