Description

Die Erfindung betrifft eine Crimppresse zur Herstellung einer Crimpverbindung mittels eines Oberwerkzeuges und eines Unterwerkzeuges, wobei das Oberwerkzeug mit einer linearen Bewegung einen auf dem Unterwerkzeug auflegbaren Crimpkontakt mit einem Leiterende vercrimpt.The invention relates to a crimping press for producing a crimp connection by means of an upper tool and a lower tool, wherein the upper tool with a linear movement crimps a auflegbaren on the lower tool crimp contact with a conductor end.

Bei den herkömmlichen Crimpwerkzeugen sind die Teile für den Kontaktvorschub, das feststehende Unterwerkzeug und das darüber in einer Führung beweglich angeordnete Oberwerkzeug als Einheit ausgeführt. Dabei werden die Kontakte horizontal oder bogenförmig zugeführt, was eine relativ breite Bauweise zur Folge hat. Um die auf Rollen aufgespulten Crimpkontakteder Presse zuzuführen sind aufwendige Aufbauten an der Kabelverarbeitungsmaschine notwendig. Diese Faktoren führen bei der konventionellen Werkzeugtechnik zu einem grossen Platzbedarf pro Crimppresse mit Werkzeug und Kontaktzuführung und einer langen Umrüstzeit, wenn die leere Kontaktrolle ersetzt oder ein anderer Kontakttyp verarbeitet werden soll.In the conventional crimping tools, the parts for the contact feed, the fixed lower tool and the upper tool movably arranged above in a guide are made as a unit. The contacts are fed horizontally or arcuately, which has a relatively wide construction result. In order to feed the crimp contacts of the press wound on rollers, complicated structures are necessary on the cable processing machine. These factors lead to a large space requirement in conventional tool technology per crimping press with tool and contact feed and a long changeover time when the empty contact roller is to be replaced or another contact type is to be processed.

Aus der Schrift JP 07320843 ist eine Crimppresse bekannt geworden, bei der gegurtete Crimpkontakte verarbeitet werden. Ein Crimpstempel stellt zusammen mit einem Amboss eine Pressverbindung zwischen einem Crimpkontakt und einem Kabel her. Die gegurteten Crimpkontakte werden auf einer kreisförmigen Kontkatführung zugeführt, wobei ein Vorschubfinger den Kontaktgurt vorwärts bewegt.From the Scriptures JP 07320843 a crimping press has become known in which strapped crimp contacts are processed. A crimping die, together with an anvil, produces a press fit between a crimp contact and a cable. The strapped crimp contacts are supplied on a circular Kontkatführung with a feed finger moves the contact belt forward.

Ein Nachteil der bekannten Einrichtung liegt darin, dass beim Wechsel des Crimpwerkzeuges oder beim Wechsel des Kontaktgurtrolle lange Stillstandszeiten entstehen. Ausserdem ist der Platzbedarf bei nebeneinander angeordneten Crimppressen wegen den seitlichen Presseaufbauten gross.A disadvantage of the known device is that long downtimes occur when changing the crimping tool or when changing the contact roller. In addition, the space required for juxtaposed crimping presses is large because of the lateral press structures.

Eine Crimppresse mit einer einschiebbaren Kassette, die beide Teile eines Crimpwerkzeuges und einen Vorrat an Crimpkontakten aufweist, ist aus Dokument FR-A-2 607 977 bekannt.A crimping press with a retractable cassette, which has both parts of a crimping tool and a supply of crimp contacts, is from document FR-A-2 607 977 known.

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 zu schaffen, die in der Breite schlank baut, konstruktiv einfach gebaut ist und kurze Werkzeugund Kontaktwechselzeiten ermöglicht.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 crimping press, which is slim in width, structurally simple in construction and allows short tool and contact change times.

Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.Advantageous developments of the invention are specified in the dependent claims.

Bei der erfindungsgemässen Crimppresse ist das Oberwerkzeug mit Crimpstempel eine Einheit, die direkt im Pressenschlitten einsetzbar ist. Das Unterwerkzeug mit Amboss und Kontaktvorschub, die Kontaktrolle und die Kontaktzuführung sind in einer Kassette zusammengefasst, die als Einschub auswechselbar ist. Dabei werden die Crimpkontakte dem Crimpwerkzeug bogenförmig zugeführt, wodurch die Crimppresse schmal baut. Der Platzbedarf in der Breite für eine Crimppresse wird etwa halbiert und die Umrüstzeit wesentlich gesenkt. Durch die mechanische Trennung des Oberwerkzeuges vom Unterwerkzeug muss der Kontaktgurt nicht mehr ausgeschlauft werden. Bei der erfindungsgemässen Crimppresse ist die Crimphöhe programmierbar (variabler unterer Totpunkt). Damit entfällt auch die manuelle Einstellung der Crimphöhe des Crimpwerkzeuges, wie sie bei herkömmlichen Werkzeugen notwendig ist.In the novel crimping press, the upper tool with crimping die is a unit which can be used directly in the press carriage. The lower tool with anvil and contact feed, the contact roller and the contact feeder are combined in a cassette, which is interchangeable as a drawer. The crimp contacts are supplied to the crimping tool arcuately, whereby the crimping press builds narrow. The space requirement in the width for a crimping press is approximately halved and the changeover time significantly reduced. Due to the mechanical separation of the upper tool from the lower tool, the contact belt no longer has to be run out. In the case of the crimping press according to the invention, the crimp height can be programmed (variable bottom dead center). This eliminates the manual adjustment of the crimp height of the crimping tool, as is necessary with conventional tools.

In die Aufnahme des Oberwerkzeuges im Pressenschlitten ist ein Kraftsensor für die Crimpkraftüberwachung integriert. Bei herkömmlichen Werkzeugen muss dieser Sensor oberhalb der Kupplung zwischen Pressenschlitten und Werkzeug oder unter der Grundplatte des Werkzeuges eingebaut werden. Das hat zur Folge, dass ausser den tatsächlichen Crimpkräften noch andere Kräfte (Kontaktvorschub, Schnittkräfte für das Abtrennen des Kontaktes vom Trägerstreifen, Reibung etc.) mitgemessen werden. Im Gegensatz dazu werden beim erfindungsgemässen Crimppressenkonzept ausschliesslich die für die Beurteilung der Qualität der Vercrimpung relevanten Kräfte gemessen.A force sensor for crimp force monitoring is integrated into the receptacle of the upper tool in the press carriage. With conventional tools, this sensor must be installed above the coupling between the press slide and the tool or under the base plate of the tool. As a result, in addition to the actual crimping forces, other forces (contact feed, cutting forces for separating the contact from the carrier strip, friction, etc.) are also measured. In contrast, the crimping press concept according to the invention exclusively measures the forces relevant for the assessment of the quality of the crimping.

A spacer 6 is interchangeable for adjusting the insulation crimp height. The knife ram 3 is mounted vertically movable in the upper tool OW, wherein the dimensions of a slot 7 limits the movement.

Das Oberwerkzeug OW wird manuell in eine am unteren Ende des Pressenschlittens 11 angeordnete Werkzeugaufnahme 10 eingesetzt und mittels eines Riegels 12 an einem Zapfen 13 gehalten. Der mittels Druckfedern 12.1 nach oben gepresste Riegel wird bei einem Werkzeugwechsel mittels eines ausfahrbaren Kolbens 14 nach unten gedrückt. Dazu muss der Kolben 14 ausgefahren werden und der Pressenschlitten 11 eine Vertikalbewegung nach oben ausführen.The upper tool OW is manually in a arranged at the lower end of the press carriage 11 tool holder 10th used and held by a bolt 12 on a pin 13. The pressed-up by means of compression springs 12.1 latch is pressed at a tool change by means of an extendable piston 14 down.

Über Auflageflächen 15 des Oberwerkzeuges werden die beim Crimpen auftretenden Kräfte an einen Kraftsensor 16 weitergegeben.Over contact surfaces 15 of the upper tool, the forces occurring during crimping are transmitted to a force sensor 16.

Fig. 6 zeigt das in die Werkzeugaufnahme eingesetzte Oberwerkzeug. Der Messerstössel 3 betätigt beim Crimpvorgang das Messer eines Unterwerkzeuges UW, mit welchem Messer ein Crimpkontakt 20 von einem Trägerstreifen 21 abgetrennt wird und der Trägerstreifen 21 zerkleinert wird. Die dabei auftretenden Kräfte fliessen nicht durch den Kraftsensor 16, da der Messerstössel 3 im Oberwerkzeug OW vertikal beweglich ist und direkt am Körper 22 des Pressenschlittens 11 aufliegt. Fig. 6 shows the upper tool used in the tool holder. The knife ram 3 is operated during the crimping process the knife of a lower tool UW, with which knife a crimp contact 20 is separated from a carrier strip 21 and the carrier strip 21 is crushed. The forces occurring do not flow through the force sensor 16, since the knife ram 3 in the upper tool OW is vertically movable and rests directly on the body 22 of the press slide 11.

Die in Fig. 2 gezeigte, von der Rückseite der Crimppresse CR her einschiebbare Kassette KA umfasst eine Kontaktrolle 30, die den Vorrat an gegurteten Crimpkontakten 20 lagert. Ein Kontaktgurt KO umschlingt eine Spannrolle 32 und wird bogenförmig 90° gedreht auf das Unterwerkzeug UW geführt. Ein Papierstreifenaufwickler 34 wird über ein Zahnrad von einem in der Crimppresse CR platzierten Gegenrad angetrieben.In the Fig. 2 shown, insertable from the back of the crimping press CR fro cassette KA comprises a contact roller 30, which stores the supply of strapped crimp contacts 20. A contact belt KO wraps around a tensioning roller 32 and is guided arcuately 90 ° turned onto the lower tool UW.

Die beiden Endpositionen der Schwenkbewegung können mit den Einstellschrauben 46.1, welche die Endlagen eines pneumatischen Vorschubantriebes 46 bestimmen, festgelegt werden. Die Umlenkung und Führung des Kontaktgurtes KO beim Vorschub wird durch die Führungsteile 47 erreicht. Diese Führungsteile 47 sind als ganzes in Kabelrichtung verstellbar, damit die Lage des Crimpkontaktes 20 auf dem Unterwerkzeug UW bzw. auf dem Amboss 42 genau bestimmt werden kann.The advance of the crimp contacts 20 is performed by a pivoting movement of a feed finger 45. This engages in transport holes of the carrier strip 21 and is designed as a spring-loaded latch, which advances the contacts 20 only during the pivoting movement upwards. The two end positions of the pivoting movement can be determined with the adjusting screws 46.1, which determine the end positions of a pneumatic feed drive 46. The deflection and guidance of the contact belt KO during feed is achieved by the guide members 47. These guide parts 47 are adjustable as a whole in the cable direction, so that the position of the crimp contact 20 on the lower tool UW or on the anvil 42 can be determined exactly.
