Description

Die Erfindung betrifft ein Verfahren und eine Einrichtung zur Steuerung eines der Verbindung eines Kontaktes mit einem Leiter dienenden Crimpvorganges, bei dem ein Crimpwerkzeug einer Crimppresse von einer Anfangsposition in eine Crimpposition und anschliessend in eine Endposition verfahren wird, wobei die Bewegung des Crimpwerkzeuges zwischen der Anfangsposition und der Endposition ihren Ursprung in einer Rotationsbewegung mit einem oberen Totpunkt und einem unteren Totpunkt hat und die Crimpposition etwa im unteren Totpunkt liegtThe invention relates to a method and a device to control the connection of a contact with a conductor serving crimping process in which a Crimping tool of a crimping press from an initial position in a crimping position and then in an end position is moved, the movement of the crimping tool between the start position and the end position their Originating in a rotational movement with an upper one Has dead center and a bottom dead center and the Crimp position is approximately at bottom dead center

Mittels einer Crimppresse werden Kontakte an elektrische zuvor abisolierte Leiter angeschlagen, wobei gleichzeitig eine Quetsch- oder Pressverbindung, auch Crimpverbindung genannt, zwischen dem Kontakt und der Leiterisolation und eine Quetsch- oder Pressverbindung zwischen dem Kontakt und dem elektrisch leitenden Leiterdraht hergestellt wird. Die Crimppresse besteht im wesentlichen aus einem Ständer, an dem ein Antrieb für ein Crimpwerkzeug angeordnet ist, einem am Ständer geführten und angetriebenen Crimpbär, der das wechselbare Werkzeug zur Herstellung der Crimpverbindung betätigt. Die für den Crimpvorgang notwendige Linerarbewegung des Werkzeuges wird beispielsweise von einer Rotationsbewegung abgeleitet, die mittels eines Motors, eines Getriebes und einer vom Getriebe angetriebenen Welle mit Exzenterzapfen erzeugt wird. Auch sind Crimppressen bekannt, bei denen die Linearbewegung direkt mittels hydraulischen und/oder pneumatischen Linearantrieben erzeugt wird.Using a crimping press, contacts are made to electrical previously stripped conductor stripped, at the same time a crimp or press connection, also crimp connection called, between the contact and the conductor insulation and a crimp or press connection between the contact and the electrically conductive conductor wire is produced. The Crimping press essentially consists of a stand which is arranged a drive for a crimping tool on the stand led and driven crimp bear that the Exchangeable tool for making the crimp connection actuated. The one necessary for the crimping process Linear movement of the tool is, for example, from derived from a rotational movement that by means of a Motors, a transmission and one from the transmission driven shaft with eccentric pin is generated. Also crimping presses are known in which the linear movement directly by means of hydraulic and / or pneumatic Linear drives is generated.

Je nach Verwendung können Grösse und Form der Kontakte stark variieren, was unterschiedliche Werkzeuge notwendig macht. Auch sind die Crimpzonen der Kontakte unterschiedlich aufgebaut. Bei der Verarbeitung eines Kontaktes mit offener Crimpzone wird der abisolierte Leiter etwa 5-10 mm über den Kontakt gebracht und in achsialer Richtung gegenüber dem Kontakt mittels Sensor genau positioniert. Beim Absenken des Werkzeuges mit den beiden Crimpstempeln, ein erster Crimpstempel für den Isolationscrimp und zweiter Crimpstempel für den Drahtcrimp, wird der Leiter mittels mechanischer Vorrichtung gehalten und durch die Werkzeugbewegung mitabgesenkt, wobei eine Crimpverbindung zwischen dem Kontakt und der Leiterisolation und eine Crimpverbindung zwischen dem Kontakt und dem elektrisch leitenden Leiterdraht hergestellt wird. Die Verarbeitung eines Kontaktes mit geschlossener Crimpzone ist aufwendiger, weil der abisolierte Leiter in eine röhrenförmige Öffnung der Crimpzone eingeführt werden muss. Die Röhre des Kontaktes wird mit entsprechender Zentrierung bei einem Zwischenstop des Werkzeuges ausgerichtet, was das Einschieben des Leiterdrahtes in die Röhre erleichtert. Die Verarbeitung von Kontakten mit geschlossener Crimpzone ist gegenüber der Verarbeitung von Kontakten mit offener Crimpzone zeitintensiver.Depending on the use, the size and shape of the contacts vary widely, which requires different tools makes. Also the crimp zones are the contacts structured differently. When processing a The stripped conductor becomes contact with an open crimp zone brought about 5-10 mm over the contact and in axial Direction compared to the contact by means of a sensor positioned. When lowering the tool with the two Crimp stamping, a first crimp stamp for the Insulation crimp and second crimp stamp for the Wire crimp, the conductor is made using mechanical Device held and by the tool movement co-lowered, with a crimp connection between the Contact and the conductor insulation and a crimp connection between the contact and the electrically conductive Conductor wire is produced. Processing a Contact with a closed crimp zone is more complex because the stripped conductor into a tubular opening of the Crimp zone must be introduced. The tube of contact with appropriate centering during a stopover of the tool, which is the insertion of the Conductor wire in the tube easier. The processing of contacts with closed crimp zone is opposite the Processing of contacts with an open crimp zone time-consuming.

Die Crimpverbindung entsteht zwischen dem beweglichen ersten bzw. zweiten Crimpstempel für den Isolationscrimp bzw. für den Drahtcrimp und einem entsprechend ausgebildeten fest angeordneten Amboss. Beim Crimpvorgang wird das Werkzeug mit den Stempeln um ein bestimmtes Mass gegen den Amboss verfahren. Vielfach wird der Kontakt ebenfalls mittels der Stempelbewegung über eine Mechanik um ein Kontaktraster vorgeschoben.The crimp connection is made between the movable one first and second crimp stamps for the insulation crimp or for the wire crimp and one accordingly trained fixed anvil. When crimping the tool with the stamps to a certain extent proceed against the anvil. In many cases, the contact also by means of the stamp movement via a mechanism a contact grid advanced.

In der Leiterverarbeitung sind hauptsächlich Crimppressen mit einem Wekzeughub von 30 mm oder 40 mm üblich. Die Crimppressen arbeiten vorwiegend auf dem Exzenterprinzip, wobei die Linearbewegung der Stempel mittels des auf der angetriebenen Welle angeordneten Exzenterzapfens erzeugt wird. Der rotierende Exzenterzapfen steht in loser Verbindung mit dem Crimpbär und bewegt diesen linear. Die Rotationsbewegung kann auch mittels eines Pleuels in die Linearbewegung umgesetzt werden. Exzenter-Crimppressen arbeiten schnell und sind billig in der Herstellung.Crimp presses are mainly used in conductor processing with a tool stroke of 30 mm or 40 mm. The Crimping presses work mainly on the eccentric principle, wherein the linear movement of the stamp by means of the driven shaft arranged eccentric pin generated becomes. The rotating eccentric pin is loose Connection with the crimp bear and moves it linearly. The Rotational movement can also be done by means of a connecting rod in the Linear motion can be implemented. Eccentric crimping presses work quickly and are cheap to manufacture.

Nachteilig bei diesen Crimppressen ist der durch den Exzenterzapfen vorgegebene feste Hub. Für Werkzeuge mit unterschiedlichen Hubhöhen muss an der Crimppresse ein mechanischer Eingriff vorgenommen werden, indem die Totpunkte des Exzenterzapfens verschoben werden oder die Welle mit dem Exzenterzapfen ausgetauscht wird. Eine nachträgliche Justierung ist in jedem Falle notwendig.A disadvantage of these crimping presses is that of the Eccentric pin predetermined fixed stroke. For tools with different lifting heights must be on the crimping press mechanical intervention can be made by the Dead centers of the eccentric pin are moved or the Shaft with the eccentric pin is exchanged. A subsequent adjustment is necessary in any case.

Aus der Schrift DE 195 48 533 ist eine Crimppresse bekannt geworden, bei der der Crimpvorgang in der oberen Totpunktlage des Exzenterzapfens beginnt. Der Crimpstempel wird dann in die Crimpstellung nahe dem unteren Totpunkt des Exzenterzapfens bewegt. Damit die Hülse des Kontaktes nicht zurückfedert wird der Crimpstempel während einer bestimmten Zeit gestoppt. Dann wird der Crimpstempel in entgegengesetzter Richtung in die obere Totpunktlage bewegt. Der vom oberen Totpunkt her gemessene Schwenkwinkel des Exzenterzapfens ist je nach der Art der Kontaktelemente wählbar und bestimmt die Crimpstellung. Dadurch muss bei der Verarbeitung von unterschiedlichen Kontaktelementen die Höhe des Ambosses nicht verändert werden.A crimping press is known from DE 195 48 533 become, in which the crimping process in the upper Dead center position of the eccentric pin begins. The crimp stamp is then in the crimp position near bottom dead center of the eccentric pin moved. So that the sleeve of the contact the crimp stamp is not rebounded during a stopped at a certain time. Then the crimp stamp is in opposite direction in the top dead center position emotional. The swivel angle measured from top dead center of the eccentric pin depends on the type of contact elements selectable and determines the crimp position. This means that at the processing of different contact elements Anvil height cannot be changed.

Nachteilig bei dieser Crimppresse ist, dass besondere Crimpstempel notwendig sind, die bei der maximalen Hubhöhe führbar sind. Ausserdem muss beim Wechseln von einer Kontaktgrösse auf eine andere Kontaktgrösse die Crimpstellung justiert und die Qualität der Crimpverbindung nachgeprüft werden. The disadvantage of this crimping press is that it is special Crimping dies are necessary at the maximum lifting height are feasible. In addition, when changing from one Contact size to another contact size Adjusted crimp position and the quality of the crimp connection be checked.

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 Crimppresse zur Herstellung von Crimpverbindungen zu schaffen, bei der der Werkzeughub einstellbar ist.The invention seeks to remedy this. The invention, as characterized in claim 1 solves the problem to avoid the disadvantages of the known device and a crimping press for making crimp connections create at which the tool stroke is adjustable.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass beim Verarbeiten von unterschiedlichen Kontakten kein Umrüsten der Crimppresse notwendig ist und dass auch kleine Kontakte verarbeitbar sind. Weiter vorteilhaft ist, dass keine Sensoren zur Überwachung der Ausgangsposition bzw. Zwischenposition des Werkzeuges mit den Stempeln notwendig sind. Mit der erfindungsgemässen Crimppresse kann ohne Veränderung der Mechanik die Anzahl der Crimpvorgänge pro Zeiteinheit wesentlich gesteigert werden. Ausserdem kennt die Steuerung der Crimppresse jederzeit die genaue Werkzeugposition, womit eine einfache Auswertung der Crimpkräfte machbar ist und andere am Crimpvorgang beteiligte Maschinen synchronisiert werden können. The advantages achieved by the invention are in essential to see in the fact that when processing different contacts no changeover of the crimping press is necessary and that even small contacts can be processed are. It is also advantageous that no sensors for Monitoring the starting position or intermediate position of the Tools with the stamps are necessary. With the Crimping press according to the invention can without changing the Mechanics the number of crimping operations per unit of time be significantly increased. The controller also knows the crimping press the exact tool position at all times, with which a simple evaluation of the crimping forces is feasible and other machines involved in the crimping process can be synchronized.

Start and end position A, E and intermediate position Z are determined using the Eccentric pin 7 detecting sensors 35, usually Proximity switch, detected and the crimp press with the corresponding signals controlled. Start and end position A, E and intermediate position Z are due to the geometric Arrangement of the sensors 35 predetermined and can only by Changing the sensor arrangement can be changed.

Die Drehbilder der Fig. 10 bis 13 zeigen die erfindungsgemässe Steuerung der Crimppresse. Bei beispielsweise den geraden Crimpvorgängen dreht der Exzenterzapfen 7 in der einen Richtung, bei den ungeraden Crimpvorgängen dreht der Exzenterzapfen 7 in entgegengesetzter Richtung. Zur Erfassung der Anfangs- und Endposition A, E sowie der Zwischenposition Z und der Crimpposition C sind keine Sensoren vorgesehen. Die Erfassung jeder beliebigen Lage des Exzenterzapfens 7 erfolgt mittels eines von der Welle 6 an.getriebenen Resolvers. Aufbau und Funktionsweise des Resolvers sind weiter unten in den Fig. 14 und 15 näher erläutert. Gemäss Fig. 11 und 13 kann eine Crimpverbindung auch mit einem kleineren Hub als der maximale Hub hergestellt werden. Die Steuerung 16 kennt jederzeit die Lage des Exzenterzapfens 7 und kann durch entsprechende Motorbefehle den Hub und somit den Crimpvorgang um den mit 36 bezeichneten Weg verkürzen. Bei einem Crimpvorgang sind Anfangs- und Endposition A, E des Exzenterzapfens 7 sind nicht mehr am gleichen Ort. Zur Änderung der Hubhöhe ist kein mechanischer Eingriff, beispielsweise ein Austausch der Welle notwendig.10 to 13 show the control of the crimping press according to the invention. at for example, the straight crimping process turns Eccentric pin 7 in one direction, in the odd The eccentric pin turns 7 in opposite direction. To capture the initial and End position A, E and the intermediate position Z and the No sensors are provided for crimping position C. The Detection of any position of the eccentric pin 7 takes place by means of a driven by the shaft 6 Resolver. Structure and mode of operation of the resolver are 14 and 15 explained in more detail below. According to 11 and 13 can also be a crimp connection with a smaller stroke than the maximum stroke. The Control 16 knows the position of the eccentric pin 7 at all times and can the stroke and thus by appropriate motor commands shorten the crimping process by the path designated 36. In a crimping process, the start and end positions are A, E of the eccentric pin 7 are no longer in the same place. to Changing the lifting height is not a mechanical intervention, For example, an exchange of the shaft is necessary.

Fig. 14 und 15 zeigen den prinzipiellen Aufbau und die Funktionsweise des Resolvers 37, der ein absolutes Signal pro Umdrehung liefert und unempfindlich gegenüber Vibrationsbelastung und Temperatur ist. Aufgrund seines mechanischen Aufbaus bleibt seine Winkelinformation auch bei Spannungsausfall erhalten. Der Resolver 37 besteht aus einem Stator 38 und einem von der Welle 6 angetriebenen Rotor 39 und dient der Messung von Winkelpositionen. Am Stator 38 ist eine erste Statorwicklung 40 und eine zweite Statorwicklung 41 sowie am Rotor 39 eine Rotorwicklung 42 angeordnet. Die Rotorwicklung 42 wird durch eine Wechselspannung U1 mit konstanter Amplitude und Frequenz, beispielsweise 5000 Hz erregt. Die zweite Statorwicklung 41 ist gegenüber der ersten Statorwicklung 40 um 90° verschoben angeordnet. Durch elektromagnetische Kopplung erzeugt die Spannung U1 an den Klemmen der Statorwicklungen 40, 41 die beiden Spannungen Usin bzw. Ucos. Diese beiden Spannungen haben die gleiche Frequenz wie U1. Die Amplitude ist aber proportional zum Sinus bzw. Cosinus des mechanischen Winkels . Die Speisung der Rotorwicklung 42 erfolgt über einen Oszillator 43. Bei einem Resolver mit einem Polpaar durchläuft die Amplitude der beiden Spannungen Usin und Ucos jeweils eine Sinusschwingung pro mechanische Umdrehung. Eine Resolverschnittstelle 44 wertet das Sinussignal und das Cosinussignal des Resolvers 37 mit beispielsweise einer Auflösung von 0,35° aus und konvertiert den Winkel  in einen digitalen Wert. Ausgangsseitig ist die Resolverschnittstelle 44 an ein Bussystem 45 der Steuerung 16 angeschlossen. 14 and 15 show the basic structure and the Operation of the resolver 37, which is an absolute signal delivers per revolution and insensitive to Vibration exposure and temperature is. Because of his mechanical construction, its angular information remains as well received in the event of a power failure. The resolver 37 consists of a stator 38 and one driven by the shaft 6 Rotor 39 and is used to measure angular positions. At the Stator 38 is a first stator winding 40 and a second Stator winding 41 and a rotor winding 42 on the rotor 39 arranged. The rotor winding 42 is replaced by a AC voltage U1 with constant amplitude and frequency, for example 5000 Hz excited. The second stator winding 41 is 90 ° with respect to the first stator winding 40 shifted. Through electromagnetic coupling generates the voltage U1 at the terminals of the stator windings 40, 41 the two voltages Usin and Ucos. These two Voltages have the same frequency as U1. The amplitude but is proportional to the sine or cosine of mechanical angle . The rotor winding 42 takes place via an oscillator 43. With a resolver with one pair of poles runs through the amplitude of the two Voltages Usin and Ucos each have a sine wave per mechanical rotation. A resolver interface 44 evaluates the sine signal and the cosine signal of the resolver 37 with for example, a resolution of 0.35 ° and converts the angle  into a digital value. On the output side, the resolver interface 44 is on Bus system 45 of controller 16 connected.
