Definitions
- the invention relates to a crimp height adjustment device for a crimping machine.
- a constant stroke is transmitted to a crimping tool, so that a specific electrical connector is crimped to an electrical conductor with a predetermined diameter in an optimal electrical contact.
- crimping machines are e.g. Eccentric presses have been developed, the connecting rod of which is arranged to be adjustable.
- the connecting rod can be empirically adjusted to a desired crimp height required to achieve an optimal crimp for a particular connector and conductor of a particular diameter.
- the optimum crimp height must be empirically determined again by mechanically adjusting the connecting rod before production can be restarted. This process requires a lot of time and special experience of the operating personnel, because very small paths have to be set with high accuracy when adjusting the crimp height. Rejects are produced in considerable quantities.
- Crimping machines are also known in which the working stroke is generated pneumatically or hydraulically and is transmitted directly to the crimping tools. over elaborate valve controls stop the working stroke after reaching a certain crimping force and initiate the return stroke. The required crimping force can only be maintained for a short time, which often does not lead to an optimal crimp. Furthermore, such systems are often adversely affected by uncontrollable pressure surges.
- a device is also known in which, after reaching a preselected crimping force, the excess working stroke is deflected onto a spring-loaded toggle lever system while maintaining the crimping force (DE-A-27 46 892).
- the spring load of the toggle lever system is adjustable, so that when changing the connector type and / or the conductor, the counterforce of the toggle lever system is adjusted in order to achieve an optimal crimp.
- This known device has proven itself in crimping devices on which changes in the type of connector and / or conductor take place in series.
- stop and crimping machines have recently been developed which are combined with line changers and to which different connectors and different lines can be fed alternately in quick succession. These machines can crimp different connectors on both sides of a line and obtain different lines via line changers. They work very quickly, but no different crimp height can be provided, which means that only a certain crimp height is used, and only connectors and conductors that require roughly the same crimp height can be processed.
- the object of the invention is to provide a device for the new generation of crimping machines with which the crimp height can be changed in accordance with the change speed for the connectors and / or lines.
- a pivot pin 2 arranged transversely to the longitudinal extent of the fork is rotatably mounted in the fork.
- a stop pin 3 extends vertically upwards from the hinge pin 2.
- the stop pin 3 passes through a horizontally extending lower guide plate 4, in which a guide bush 5 is seated.
- the stop pin 3 can slide up and down in accordance with the movement of the connecting rod 1; because the lower guide plate 4 is fastened with vertically downwardly extending side walls 6 on the machine frame, not shown.
- a rigid housing 7 with two side walls 8, 9 and a top wall 10 is fixedly arranged above the lower guide plate 4.
- an upper guide web 11 is fastened between the side walls 8, 9, in which a further guide bush 12 is supported, which is positively penetrated by the stop pin 3.
- the stop pin 3 is thus supported laterally twice and is guided in the bushes 5 and 12.
- the stop bolt 3 ends with a bolt head 3 a, which protrudes over the edge of the bush 12.
- a bearing block 13 is positioned above the guide web 11, which is narrower than the width of the side walls 8, 9, and above the bolt head 3a and below the ceiling wall 10 at a distance from the latter, which goes back and forth in the direction of the arrow 14 and in the direction of the arrow 15 can be moved back and forth laterally.
- the bearing block 13 In the bearing block 13, four vertical bores are positioned in the square. In the bores sit positively and slidably cylindrical pins 16, which are equipped above the bearing block 13 with cylindrical stop caps 17, the diameter of which is larger than the diameter of the pins 16 and which can thus rest with their lower edge on the surface of the bearing block 13 .
- the pins 16 protrude a little downward from the bearing block 13 of equal length, their flat lower surface being at the height or at a minimal distance from the flat surface 3b of the bolt head 3.
- the bolt head 3b has a chamfer 3c on the outside edge.
- the four caps each have a different height, calculated from the surface of the bearing block 13, so that their free surfaces 17a are at a different distance from the lower surface of the ceiling wall 10.
- the lower surface of the top wall 10 is expediently formed by a metal stop plate 18 of particular hardness.
- the different spacing of the surfaces 17a of the caps 17 from the lower surface of the ceiling wall 10 ensures a different crimp height depending on the stop cap 17 located above the stop bolt 3; because the stop pin is pushed up by the connecting rod 1, presses under the cap pin 16 located above it and pushes it up with the stop cap 17 until the cap surface 17a abuts the lower surface of the stop plate 18. This stops the connecting rod movement and limits the path of the crimping tool, so that a certain crimp height is reached. If a different crimp height is desired after changing the connector type and / or the diameter of a line, another cap 17 with bolts 16 is pushed over the bolt head 3a with the aid of the bearing block 13.
- the displacement of the bearing block 13 in the double arrow direction 14 and 15 is accomplished by a cross slide 20.
- the cross slide 20 consists of a metal plate 19 arranged horizontally between the side walls 8 and 9 behind the bearing block 13, which is made narrower than the distance between the walls 8 and 9.
- In the metal plate 19 are two bores 21 arranged at a distance from one another and parallel to one another, which extend continuously from one side surface 22 opposite one of the walls 8 or 9 to the other side surface 22 (not visible in the drawing).
- the bores 21 are positively penetrated by a guide rod 23.
- the guide rods 23 are fastened in the walls 8 and 9.
- the metal plate 19 can be moved in the double arrow direction 15 on these guide rods.
- a double-acting piston-cylinder arrangement 24 is provided, the cylinder 25 of which is fastened in a passage of the wall 8 or 9, the piston rod 26 being fastened to the metal plate 19 between the two bores 21.
- the piston-cylinder arrangement 24 the metal plate 19 is selectively movable in the double arrow direction 15 predeterminable distances.
- Two blocks 27, 27a arranged one behind the other in the direction of the arrow 14 are fixedly arranged on the metal plate 19 in the region of the side surfaces 22.
- the blocks 27 and 27a are each penetrated by a bore 28 in the direction of the arrow 14, which are arranged in alignment with one another.
- the bores 28 are positively penetrated by a slide rod 28 which projects out of the block 27 to the front and a bit to the rear from the block 27a.
- the end of the part of the slide rod 29 protruding from the block 27 is fastened to the rear front of the bearing block 13.
- a locking block 30 is - viewed from the front - initially floating freely above and behind it a cylinder 32 of a further double-acting cylinder Piston-cylinder arrangement 31 fixedly arranged on the metal plate 19.
- the piston rod (not visible in the drawing) of the piston-cylinder arrangement 31 extends in the direction of arrow 14 to the locking block 30, the free end of the piston rod being fastened to the rear face of the locking block 30.
- the locking block 30 has a frontal bore 33 in which a cylindrical bolt 34 is positively inserted, which is fastened to the rear front of the metal plate 19 and can be unlocked in the locking block 30 with a handle 35 and clamped with corresponding locking elements.
- the bearing block 13 together with the slide rods 29 can be pulled out of the housing 7 to the front and either replaced by another bearing block or reinserted and locked after replacing stop caps.
- the bearing block 13 can thus be displaced a preselectable distance in the double arrow direction 14.
- the cross slide 20 and the bearing block 13 are shifted in the double arrow direction 15, while only the bearing block 13 is shifted in the double arrow direction 14.

Description
Die Erfindung betrifft eine Crimphöhenverstellvorrichtung für eine Crimpmaschine.The invention relates to a crimp height adjustment device for a crimping machine.
In einer Crimpmaschine wird auf ein Crimpwerkzeug ein konstanter Hub übertragen, so daß ein bestimmter elektrischer Verbinder an einen elektrischen Leiter mit vorbestimmtem Durchmesser elektrisch optimal kontaktierend gecrimpt wird.In a crimping machine, a constant stroke is transmitted to a crimping tool, so that a specific electrical connector is crimped to an electrical conductor with a predetermined diameter in an optimal electrical contact.
Um eine Crimpmaschine auf andere Crimphöhen z.B. beim Wechsel der Verbinderart und/oder der Leiterdurchmesser einrichten zu können, sind Crimpmaschinen z.B. Exzenterpressen entwickelt worden, deren Pleuelstange verstellbar angeordnet ist. Die Pleuelstange kann empirisch auf eine gewünschte Crimphöhe eingestellt werden, die zur Erzielung eines optimalen Crimps für einen bestimmten Verbinder und einen Leiter bestimmten Durchmessers erforderlich ist. Beim Wechseln des Leiterdurchmessers oder der Verbinderart muß die optimale Crimphöhe durch mechanische Verstellung der Pleuelstange erneut empirisch ermittelt werden, bevor die Produktion wieder aufgenommen werden kann. Dieser Vorgang erfordert sehr viel Zeit und besondere Erfahrung des Bedienungspersonals, weil bei der Crimphöhenverstellung sehr geringe Wege mit hoher Genauigkeit eingestellt werden müssen. Dabei wird Ausschuß in erheblicher Menge produziert.To move a crimping machine to other crimping heights e.g. To be able to set up when changing the connector type and / or the conductor diameter, crimping machines are e.g. Eccentric presses have been developed, the connecting rod of which is arranged to be adjustable. The connecting rod can be empirically adjusted to a desired crimp height required to achieve an optimal crimp for a particular connector and conductor of a particular diameter. When changing the conductor diameter or type of connector, the optimum crimp height must be empirically determined again by mechanically adjusting the connecting rod before production can be restarted. This process requires a lot of time and special experience of the operating personnel, because very small paths have to be set with high accuracy when adjusting the crimp height. Rejects are produced in considerable quantities.
Es sind außerdem Crimpmaschinen bekannt, bei denen der Arbeitshub pneumatisch oder hydraulisch erzeugt und direkt auf die Crimpwerkzeuge übertragen wird. Über aufwendige Ventilsteuerungen wird nach Erreichen einer bestimmten Crimpkraft der Arbeitshub gestoppt und der Rückhub eingeleitet. Dabei kann die erforderliche Crimpkraft nur kurzzeitig aufrechterhalten werden, was vielfach nicht zu einem optimalen Crimp führt. Ferner werden derartige Anlagen häufig durch unkontrollierbare Druckstöße beeinträchtigt.Crimping machines are also known in which the working stroke is generated pneumatically or hydraulically and is transmitted directly to the crimping tools. over elaborate valve controls stop the working stroke after reaching a certain crimping force and initiate the return stroke. The required crimping force can only be maintained for a short time, which often does not lead to an optimal crimp. Furthermore, such systems are often adversely affected by uncontrollable pressure surges.
Es ist ferner eine Vorrichtung bekannt, in der nach Erreichen einer vorgewählten Crimpkraft der überschüssige Arbeitshub unter Aufrechterhaltung der Crimpkraft auf ein federbelastetes Kniehebelsystem abgelenkt wird (DE-A-27 46 892). Die Federbelastung des Kniehebelsystems ist einstellbar, so daß beim Wechsel der Verbinderart und/oder des Leiters die Gegenkraft des Kniehebelsystems verstellt wird, um einen optimalen Crimp zu erreichen. Diese bekannte Vorrichtung hat sich bewährt bei Crimpvorrichtungen, auf denen serienweise Wechsel der Verbinderart und/oder Leiter stattfinden.A device is also known in which, after reaching a preselected crimping force, the excess working stroke is deflected onto a spring-loaded toggle lever system while maintaining the crimping force (DE-A-27 46 892). The spring load of the toggle lever system is adjustable, so that when changing the connector type and / or the conductor, the counterforce of the toggle lever system is adjusted in order to achieve an optimal crimp. This known device has proven itself in crimping devices on which changes in the type of connector and / or conductor take place in series.
Neuerlich sind aber Anschlag- und Crimpmaschinen entwikkelt worden, die mit Leitungswechslern kombiniert sind und denen unterschiedliche Verbinder und unterschiedliche Leitungen in kurzer Folge wechselnd zugeführt werden können. Diese Maschinen können beidseitig an eine Leitung jeweils unterschiedliche Verbinder crimpen und unterschiedliche Leitungen über Leitungswechsler beziehen. Sie arbeiten sehr schnell, wobei aber keine unterschiedliche Crimphöhe zur Verfügung gestellt werden kann, was bedeutet, daß nur mit einer bestimmten Crimphöhe gearbeitet wird, und auch nur Verbinder und Leiter verarbeitat werden können, die in etwa die gleiche Crimphöhe erfordern.However, stop and crimping machines have recently been developed which are combined with line changers and to which different connectors and different lines can be fed alternately in quick succession. These machines can crimp different connectors on both sides of a line and obtain different lines via line changers. They work very quickly, but no different crimp height can be provided, which means that only a certain crimp height is used, and only connectors and conductors that require roughly the same crimp height can be processed.
Aufgabe der Erfindung ist, eine Vorrichtung für die neue Crimpmaschinengeneration zu schaffen, mit der - der Wechselgeschwindigkeit für die Verbinder und/oder Leitungen entsprechend - die Crimphöhe gewechselt werden kann.The object of the invention is to provide a device for the new generation of crimping machines with which the crimp height can be changed in accordance with the change speed for the connectors and / or lines.
Diese Aufgabe wird durch die Merkmale des Hauptanspruchs gelöst. Vorteilhafte Weiterbildungen der Erfindung werden in den Unteransprüchen gekennzeichnet.This object is solved by the features of the main claim. Advantageous developments of the invention are characterized in the subclaims.
Anhand des in der Zeichnung perspektivisch und teilbereichsweise im Schnitt sowie teilbereichsweise aufgebrochen dargestellten Beispiels wird die Erfindung im folgenden näher erläutert.The invention is explained in more detail below on the basis of the example shown in perspective in the drawing and partly in section and partly broken away.
Von der Antriebseinrichtung und den Crimpwerkzeugen der Crimpmaschine ist lediglich das obere Ende der Gabel 1 der Pleuelstange abgebildet. Alle anderen Teile der Crimpmaschine weisen eine übliche Bauart auf und werden deshalb nicht beschrieben.Of the drive device and the crimping tools of the crimping machine, only the upper end of the
Am oberen Ende der Gabel 1 ist ein quer zur Längserstrekkung der Gabel angeordneter Gelenkbolzen 2 in der Gabel drehbar gelagert. Vom Gelenkbolzen 2 erstreckt sich vertikal nach oben ein Anschlagbolzen 3. Der Anschlagbolzen 3 durchgreift eine sich horizontal erstreckende untere Führungsplatte 4, in der eine Führungsbuchse 5 sitzt. In der Führungsbuchse 5 kann der Anschlagbolzen 3 der Bewegung der Pleuelstange 1 entsprechend auf und ab gleiten; denn die untere Führungsplatte 4 ist mit sich vertikal nach unten erstreckenden Seitenwänden 6 am nicht dargestellten Maschinenrahmen befestigt.At the upper end of the fork 1 a
Über der unteren Führungsplatte 4 ist ein starres Gehäuse 7 mit zwei Seitenwänden 8, 9 und einer Deckenwandung 10 fest angeordnet. In etwa halber Höhe des Gehäuses 7 ist zwischen den Seitenwänden 8, 9 ein oberer Führungssteg 11 befestigt, in dem eine weitere Führungsbuchse 12 lagert, die vom Anschlagbolzen 3 formschlüssig durchgriffen wird. Der Anschlagbolzen 3 ist somit zweifach seitlich abgestützt und wird in den Buchsen 5 und 12 geführt. Der Anschlagbolzen 3 endet mit einem Bolzenkopf 3a, der über den Rand der Buchse 12 kragt.A
Über dem Führungssteg 11, der schmaler ist, als die Breite der Seitenwände 8, 9 beträgt, und über dem Bolzenkopf 3a sowie unter der Deckenwandung 10 im Abstand von letzterer ist ein Lagerblock 13 positioniert, der in Pfeilrichtung 14 vor und zurück sowie in Pfeilrichtung 15 seitlich hin und her verschoben werden kann.A
Im Lagerblock 13 sind vier vertikale Bohrungen im Viereck positioniert eingebracht. In den Bohrungen sitzen formschlüssig und gleitbar zylindrische Zapfen 16, die oberhalb des Lagerblocks 13 mit zylindrischen Anschlagkappen 17 ausgerüstet sind, deren Durchmesser größer ist, als der Durchmesser der Zapfen 16 beträgt und die somit mit ihrem unteren Rand auf der Oberfläche des Lagerblocks 13 aufsitzen können. Die Zapfen 16 ragen ein Stück nach unten aus dem Lagerblock 13 gleichlang heraus, wobei sich ihre ebene Unterfläche in Höhe bzw. in einem minimalen Abstand der ebenen Oberfläche 3b des Bolzenkopfs 3 befinden. Der Bolzenkopf 3b weist außenrandseitig eine Anfasung 3c auf.In the
Wesentlich ist, daß die vier Kappen jeweils eine unterschiedliche Höhe, gerechnet von der Oberfläche des Lagerblocks 13, aufweisen, so daß ihre freien Oberflächen 17a einen unterschiedlichen Abstand zur Unterfläche der Deckenwandung 10 haben. Die Unterfläche der Deckenwandung 10 wird zweckmäßigerweise von einer metallenen Anschlagplatte 18 besonderer Härte gebildet.It is essential that the four caps each have a different height, calculated from the surface of the
Der unterschiedliche Abstand der Oberflächen 17a der Kappen 17 von der Unterfläche der Deckenwandung 10 gewährleistet eine unterschiedliche Crimphöhe in Abhängigkeit von der jeweils sich über dem Anschlagbolzen 3 befindlichen Anschlagkappe 17; denn der Anschlagbolzen wird von der Pleuelstange 1 nach oben gestoßen, drückt unter den über ihm befindlichen Kappenzapfen 16 und schiebt diesen mit der Anschlagkappe 17 nach oben, bis die Kappenoberfläche 17a an die Unterfläche der Anschlagplatte 18 stößt. Damit wird die Pleuelbewegung gestoppt und der Weg des Crimpwerkzeuges begrenzt, so daß eine bestimmte Crimphöhe erreicht wird. Soll eine andere Crimphöhe nach einem Wechsel der Verbinderart und/oder des Durchmessers einer Leitung gewünscht werden, wird eine andere Kappe 17 mit Bolzen 16 mit Hilfe des Lagerblocks 13 über den Bolzenkopf 3a geschoben.The different spacing of the
Die Verschiebung des Lagerblocks 13 in Doppelpfeilrichtung 14 und 15 wird durch einen Kreuzschlitten 20 bewerkstelligt. Der Kreuzschlitten 20 besteht aus einer horizontal zwischen den Seitenwandungen 8 und 9 hinter dem Lagerblock 13 angeordneten Metallplatte 19, die schmaler ausgeführt ist, als der Abstand zwischen den Wandungen 8 und 9 beträgt. In die Metallplatte 19 sind zwei im Abstand voneinander und parallel zueinander angeordnete Bohrungen 21 eingebracht, die sich von einer einer der Wandungen 8 oder 9 gegenüberliegenden Seitenfläche 22 zur anderen Seitenfläche 22 (nicht sichtbar in der Zeichnung) durchgehend erstrecken. Die Bohrungen 21 werden von je einer Führungsstange 23 formschlüssig durchgriffen. Die Führungsstangen 23 sind in den Wandungen 8 und 9 befestigt. Auf diesen Führungsstangen kann die Metallplatte 19 in Doppelpfeilrichtung 15 bewegt werden. Für die Ausübung dieser Bewegung ist eine doppelt wirkende Kolbenzylinderanordnung 24 vorgesehen, deren Zylinder 25 in einem Durchgang der Wandung 8 oder 9 befestigt ist, wobei die Kolbenstange 26 zwischen den beiden Bohrungen 21 an der Metalplatte 19 befestigt ist. Mit der Kolbenzylinderanordnung 24 ist die Metallplatte 19 wählbar in Doppelpfeilrichtung 15 vorbestimmbare Wegstrecken verfahrbar.The displacement of the
Auf der Metallplatte 19 sind jeweils im Bereich der Seitenflächen 22 zwei in Pfeilrichtung 14 im Abstand voneinander hintereinander angeordnete Blöcke 27, 27a fest angeordnet. Die Blöcke 27 und 27a werden von je einer Bohrung 28 in Pfeilrichtung 14 durchsetzt, die fluchtend zueinander angeordnet sind. Die Bohrungen 28 werden formschlüssig von einer Gleitstange 28 durchsetzt, die aus dem Block 27 nach vorne und aus dem Block 27a ein Stück nach hinten herausragt. Das Ende des aus dem Block 27 herausragenden Teils der Gleitstange 29 ist an der Rückfront des Lagerblocks 13 befestigt. Zwischen den beiden Blocksystemen, bestehend jeweils aus den Blöcken 27 und 27a, ist - von vorne betrachtet - zunächst ein Verriegelungsblock 30 frei schwebend über und dahinter im Abstand ein Zylinder 32 einer weiteren doppelt wirkenden Kolbenzylinderanordnung 31 fest auf der Metallplatte 19 angeordnet. Die Kolbenstange (nicht sichtbar in der Zeichnung) der Kolbenzylinderanordnung 31 erstreckt sich in Pfeilrichtung 14 zum Verriegelungsblock 30, wobei das freie Ende der Kolbenstange an der Rückfront des Verriegelungsblocks 30 befestigt ist. Der Verriegelungsblock 30 weist eine frontale Bohrung 33 auf, in der ein zylindrischer Bolzen 34 formschlüssig steckt, der an der Rückfront der Metallplatte 19 befestigt ist und im Verriegelungsblock 30 mit einem Handgriff 35 entriegelbar und mit entsprechenden Verriegelungselementen festgeklemmt sitzt. Nach der Entriegelung kann der Lagerblock 13 zusammen mit den Gleitstangen 29 nach vorne aus dem Gehäuse 7 herausgezogen werden und entweder durch einen anderen Lagerblock ausgetauscht oder nach Auswechseln von Anschlagkappen wieder eingesetzt und verriegelt werden.Two
Mit der Kolbenzylinderanordnung 31 kann somit der Lagerblock 13 in Doppelpfeilrichtung 14 eine vorwählbare Wegstrecke verschoben werden. In Doppelpfeilrichtung 15 werden der Kreuzschlitten 20 und der Lagerblock 13 verschoben, während in Doppelpfeilrichtung 14 lediglich der Lagerblock 13 verschoben wird.With the piston-
