Description

In einer Crimppresse wird auf ein Crimpwerkzeug ein konstanter vertikaler Hub übertragen, so daß ein bestimmtes elektrisches Kontaktelement an einen elektrischen Leiterdraht vorbestimmten Durchmessers gecrimpt werden kann.In a crimping press, a constant vertical stroke is transmitted to a crimping tool, so that a specific electrical contact element can be crimped onto an electrical conductor wire of a predetermined diameter.

Gewöhnlich befinden sich die Oberstempel eines Crimpwerkzeugs, bestehend aus dem Aderstempel und dem Isolationsstempel, in einem auswechselbaren Werkzeugkopf, während der Amboß oder Unterstempel im Pressentisch angeordnet ist.The upper punches of a crimping tool, consisting of the wire stamp and the insulation stamp, are usually located in an exchangeable tool head, while the anvil or lower punch is arranged in the press table.

Der Werkzeugkopf weist oberseitig über einem Crimphöhen-Stellrad einen überstehenden T-Bolzen auf, der in eine entsprechende T-Nut bzw. T-Aufnahme des Stößels der Crimppresse eingeschoben und dort befestigt werden kann, so daß die Stößelunterfläche der Stellradoberfläche gegenüberliegend angeordnet ist. Der Werkzeugkopf ist somit aufgrund dieser einfachen Verbindungsmittel leicht auswechselbar am Stößel angeordnet.The tool head has a protruding T-bolt above a crimp height adjusting wheel, which can be inserted into a corresponding T-slot or T-receptacle of the tappet of the crimping press and fastened there, so that the tappet lower surface is arranged opposite the adjusting wheel surface. The tool head is thus easily replaceable on the ram due to these simple connecting means.

Beim Abwärtshub des Stößels der Crimppresse legt sich das Stellrad an der unteren Fläche des Stößels an. Zwischen den Oberstempeln sowie dem Amboß bzw. Unterstempel wird der Crimpvorgang beim Durchlauf des Stößels beim unteren Totpunkt (UT) durchgeführt. Der T-Bolzen dient als Mitnehmer für den Werkzeugkopf in die Ausgangsstellung bzw. in den oberen Totpunkt (OT).During the downward stroke of the ram of the crimping press, the adjusting wheel contacts the lower surface of the ram. Between the upper punches and the anvil or lower stamp, the crimping process is carried out when the plunger passes through at bottom dead center (UT). The T-bolt serves as a driver for the tool head in the starting position or in top dead center (TDC).

Bei den bekannten Werkzeugköpfen kann der T-Bolzen ein vertikales Spiel in der T-Nut bzw. der T-Aufnahme aufweisen, das z.B. bis zu 1,4 mm betragen kann. Dieses Spiel bewirkt bei einem Leerhub des Werkzeugs nach Erreichen des UT ein Voreilen des Werkzeugkopfes mit der Folge, daß die Oberstempel auf den Unterstempel geschleudert werden, was zu Beschädigungen bis zur Zerstörung der Stempel führen kann.In the known tool heads, the T-bolt can have a vertical play in the T-slot or the T-holder, which e.g. can be up to 1.4 mm. This play causes the tool head to advance when the tool is idle after reaching the UT, with the result that the upper punches are thrown onto the lower punch, which can lead to damage or even destruction of the punches.

Zur Lösung dieses Problems ist es bekannt, zum Einspannen des T-Bolzens Keileinrichtungen zu verwenden. Keile führen aber zu Verkippungen des Werkzeugkopfes, woraus ein erheblicher Verschleiß in den Führungselementen für den Werkzeugkopf resultiert.To solve this problem, it is known to use wedge devices for clamping the T-bolt. However, wedges lead to tilting of the tool head, which results in considerable wear in the guide elements for the tool head.

Aufgabe der Erfindung ist, einen Werkzeugkopf mit einer einfach aufgebauten Einspanneinrichtung zu schaffen, mit der beim Voreilen der Oberstempel im Leerhub eine Beeinträchtigung der Stempel mit Sicherheit vermieden werden kann.The object of the invention is to provide a tool head with a simply constructed clamping device, with which an impairment of the punches can be avoided with certainty when the upper punches advance in the idle stroke.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung werden in den Unteransprüchen gekennzeichnet. Anhand der Zeichnung wird die Erfindung im folgenden beispielhaft näher erläutert. Es zeigen:

  • Fig. 1 perspektivisch einen Werkzeugkopf;
  • Fig. 2 perspektivisch im Teilschnitt die erfindungsgemäße Einspanneinrichtung des Werkzeugkopfs.
This object is solved by the features of claim 1. Advantageous developments of the invention are characterized in the subclaims. The invention is explained in more detail below by way of example with reference to the drawing. Show it:
  • 1 perspective of a tool head;
  • Fig. 2 in perspective in partial section the clamping device of the tool head according to the invention.

Der in Fig. 1 gezeigte Werkzeugkopf 1 ist für eine Crimppresse bestimmt, von der lediglich in strichpunktierten Linien der Anschlußabschnitt 2 des Pressenstößels dargestellt ist, an den der Werkzeugkopf 1 über eine an seinem oberen Ende vorgesehenen Einspanneinrichtung 3 anschließbar ist. Am unteren Ende des Werkzeugkopfes 1 sind die beiden Oberstempel eines Crimpwerkzeugs, bestehend aus dem Aderstempel 4 und dem Isolationsstempel 5 angeschlossen. Die beiden Oberstempel 4 und 5 wirken mit dem Amboß bzw. dem Unterstempel 6 in einem nicht dargestellten Pressentisch zusammen. Der Werkzeugkopf 1 umfaßt ferner ein Gehäuse 7, das von außen zugängliche Stellglieder des Werkzeugkopfs sowie eine Lagerung für die Oberstempel 4 und 5 einschließt. Zu den Stellgliedern gehört ein Zahnrad 8, das in Eingriff mit einem Keilantrieb zur Höheneinstellung des Aderstempels 4 steht. Dazu gehört ferner ein Stellrad 9, das umfangsmäßig mit einem Zahnkranz versehen ist und zur Einstellung der Crimphöhe dient. Nach der Höheneinstellung über einen das Gehäuse 7 durchsetzenden Exenterstift 10 wird das Höhenstellrad 9 gegen die Anlagefläche eines Koppelstücks 11 gepreßt, an das die beiden Oberstempel 4 und 5 angeschlossen sind, von denen der Isolationsstempel 4 über separat einstellbare Keile 12 und 13, angetrieben durch das Zahnrad 8 einstellbar ist (siehe Fig. 2). Die Crimpkraft wird demnach über das Koppelstück 11 direkt auf den Aderstempel 4 sowie über die Keile 12 und 13 auf den Isolationsstempel 5 übertragen.The tool head 1 shown in FIG. 1 is intended for a crimping press, of which the connection section 2 of the press ram is shown only in dash-dotted lines, to which the tool head 1 can be connected via a clamping device 3 provided at its upper end. At the lower end of the tool head 1, the two upper punches of a crimping tool, consisting of the wire punch 4 and the insulation punch 5, are connected. The two upper punches 4 and 5 interact with the anvil and the lower punch 6 in a press table, not shown. The tool head 1 further comprises a housing 7, which includes actuators of the tool head which are accessible from the outside and a bearing for the upper punches 4 and 5. The actuators include a gear wheel 8, which is in engagement with a wedge drive for adjusting the height of the wire punch 4. This also includes an adjusting wheel 9, which is provided with a ring gear circumferentially and is used to adjust the crimp height. After adjusting the height via an eccentric pin 10 passing through the housing 7, the height adjusting wheel 9 is pressed against the contact surface of a coupling piece 11, to which the two upper punches 4 and 5 are connected, of which the insulation punch 4 is driven by separately adjustable wedges 12 and 13 Gear 8 is adjustable (see Fig. 2). The crimping force is therefore transmitted directly to the wire stamp 4 via the coupling piece 11 and to the insulation stamp 5 via the wedges 12 and 13.

Die erfindungsgemäße Einspanneinrichtung 3 umfaßt einen T-Bolzen 14, dessen kreisscheibenförmiger Kopf 15 über einen einteilig mit diesem ausgebildeten zylindrischen Schaft 16 geringeren Durchmessers mit dem Stellrad 9 verbunden und koaxial zu diesem ausgerichtet ist. Der untere Anschlußabschnitt 2 des Pressenstößels ist im Querschnitt allgemein U-förmig ausgebildet und enthält in der unteren, dem Werkzeugkopf gegenüberliegenden Seite eine T-Nut 17, in welche der T-Bolzen 14 eingeschoben werden kann. Der Werkzeugkopf 1 ist aufgrund dieses Einspannmittels leicht auswechselbar mit dem Stößel verbunden.The clamping device 3 according to the invention comprises a T-bolt 14, the circular disk-shaped head 15 of which is connected to the adjusting wheel 9 via a cylindrical shaft 16 of smaller diameter which is formed in one piece therewith and is aligned coaxially with this. The lower connecting section 2 of the press ram is generally U-shaped in cross section and contains a T-groove 17 in the lower side opposite the tool head, into which the T-bolt 14 can be inserted. The tool head 1 is connected to the plunger easily replaceable due to this clamping means.

Beim Abwärtshub des Stößels der Crimppresse legt sich das Stellrad 9 an der unteren Fläche des Stößelanschlußteils 2 an, und zwischen den Oberstempeln 4, 5 sowie dem Unterstempel 6 wird der Crimpvorgang beim Durchlauf des Stößels im unteren Totpunkt (UT) durchgeführt. Der T-Bolzen 14 dient dabei als Mitnehmer für den Werkzeugkopf 1 in die Ausgangsstellung bzw. in den oberen Totpunkt (OT).During the downward stroke of the ram of the crimping press, the adjusting wheel 9 bears against the lower surface of the ram connecting part 2, and between the upper rams 4, 5 and the lower ram 6, the crimping process is carried out when the ram passes through bottom dead center (UT). The T-bolt 14 serves as a driver for the tool head 1 in the starting position or in the top dead center (TDC).

Um das beim Stand der Technik fertigungstechnisch verursachte Voreilen des Werkzeugkopfes 1 mit der Folge, daß die Oberstempel 4, 5 auf den Unterstempel 6 geschleudert werden, zu vermeiden, ist es erfindungsgemäß vorgesehen, die Einspanneinrichtung 3 einstellbar so auszulegen, daß der T-Bolzen 14 gegenüber der T-Aufnahme 16 keinerlei Spiel aufweist.In order to ver the leading of the tool head 1 caused by manufacturing technology in the prior art, with the result that the upper punches 4, 5 are thrown onto the lower punch 6 avoid, it is provided according to the invention to design the clamping device 3 so that the T-bolt 14 has no play with respect to the T-holder 16.

Wie Fig. 2 zeigt, ist der T-Bolzen 14 zu diesem Zweck axial verstellbar im Stellrad 9 gelagert. Hierzu umfaßt das Stellrad 9 eine koaxial zur Stellradachse verlaufende Bohrung im Bereich einer einstückig mit dem Stellrad ausgebildeten Habe 18, 19, die beidseitig vom Stellrad axial vorsteht. Diese Bohrung ist im oberen Teil 18 der Nabe ausgebildet, erstreckt sich bis zum Boden des unteren Nabenteils 19 und weist ein Innengewinde auf, das mit einem Außengewinde zusammenwirkt, das an der Außenumfangsfläche des Schafts 16 des T-Bolzens 14 ausgebildet ist, der in die Sacklochbohrung des Stellrads eingesetzt ist. Aufgrund dieser Gewinde läßt sich der T-Bolzen 14 in das Stellrad 9 hinein und aus diesem heraus schrauben, wodurch sich das Maß X zwischen der Oberseite 20 des Stellrads 9 und der Unterseite 21 des Kopfes 15 des T-Bolzens 14 einstellen läßt, und zwar auf das exakte Maß Y des Pressbärens 22 der T-Aufnahme 17 am Crimppressenstößel.2 shows, the T-bolt 14 is axially adjustable in the setting wheel 9 for this purpose. For this purpose, the setting wheel 9 comprises a bore which runs coaxially to the setting wheel axis in the region of a piece 18, 19 which is formed in one piece with the setting wheel and projects axially on both sides of the setting wheel. This bore is formed in the upper part 18 of the hub, extends to the bottom of the lower hub part 19 and has an internal thread which interacts with an external thread which is formed on the outer circumferential surface of the shaft 16 of the T-bolt 14, which in the Blind hole of the adjusting wheel is inserted. Because of this thread, the T-bolt 14 can be screwed into and out of the adjusting wheel 9, as a result of which the dimension X between the upper side 20 of the adjusting wheel 9 and the underside 21 of the head 15 of the T-bolt 14 can be adjusted, specifically to the exact dimension Y of the pressbear 22 of the T receptacle 17 on the crimping press ram.

Das eingestellte Maß X wird erfindungsgemäß mittels einer Arretiereinrichtung dauerhaft lösbar festgelegt. Die Arretiereinrichtung umfaßt vorzugsweise einen Gewindestift 23, der mit einem Außengewinde versehen ist und in das Innengewinde in einer durchgehenden Bohrung 24 des T-Bolzens 14 eingreift sowie in das Sackloch des Stellrads 9 im Bereich des unteren Nabenteils 19 reicht. Der Gewindestift 23 ist als Nabenschraube ausgebildet, die zur Verstellung über die Bohrung 24 zugänglich ist, die in die Oberseite des Kopfes 15 des T-Bolzens 14 mündet.According to the invention, the set dimension X is permanently detachable by means of a locking device. The locking device preferably comprises a grub screw 23, which is provided with an external thread and engages in the internal thread in a through bore 24 of the T-bolt 14 and extends into the blind hole of the adjusting wheel 9 in the region of the lower hub part 19. The setscrew 23 is designed as a hub screw, which is accessible for adjustment via the bore 24, which opens into the top of the head 15 of the T-bolt 14.

Die Einstellung des Maßes X bzw. dessen Anpassung an das Maß Y erfolgt dadurch, daß der auf den Boden des Sacklochs drückende Gewindestift 23 gelockert wird. Daraufhin wird der T-Bolzen 14 entsprechend aus dem Stellrad 9 heraus oder in dieses hineingeschraubt, und das derart korrekt eingestellte Maß X wird dadurch gesichert, daß der Gewindestift 23 in den T-Bolzen 14 hineingeschraubt wird, bis er auf den Boden des Sacklochs stößt. Durch weiteres Drehen am Gewindestift 23 wird der Stift auf den Boden des Sacklochs gepreßt und verklemmt dadurch das Außengewinde des T-Bolzens 14 mit dem Innengewinde der Nabe des Stellrades 9. Ein fester Sitz des T-Bolzens ist damit gesichert.The setting of the dimension X or its adaptation to the dimension Y is carried out by loosening the threaded pin 23 pressing on the bottom of the blind hole. Thereupon, the T-bolt 14 is screwed out of or into the adjusting wheel 9 accordingly, and the dimension X correctly set in this way is secured by screwing the threaded pin 23 into the T-bolt 14 until it hits the bottom of the blind hole . By turning the threaded pin 23 further, the pin is pressed onto the bottom of the blind hole and thereby clamps the external thread of the T-bolt 14 with the internal thread of the hub of the adjusting wheel 9. A tight fit of the T-bolt is thus ensured.

Alternativ zu dem vorstehend beschriebenen Ausführungsbeispiel kann der zur Arretierung dienende Gewindestift auch als drehbarer sowie axial feststehend im Schaft des T-Bolzens gelagerter Stift ausgebildet sein, der an seinem anderen Ende mit einem Außengewinde versehen ist das mit dem Innengewinde im unteren Nabenteil 19 des Stellrades 9 zusammenwirkt. Das Sichern des Maßes X wird dann dadurch erreicht, daß der Arretierstift mit seinem Innengewinde im Stellrad 9 verspannt wird.As an alternative to the exemplary embodiment described above, the set screw used for locking can also be designed as a rotatable and axially fixed pin mounted in the shaft of the T-bolt, which is provided at its other end with an external thread with the internal thread in the lower hub part 19 of the adjusting wheel 9 cooperates. The securing of dimension X is then achieved in that the locking pin is clamped with its internal thread in the adjusting wheel 9.
