Description
S ta n z a u t o m a t S ta n z a u t o m a t
Die Erfindung betrifft einen Stanzautomaten mit in zueinander rechtwinklig in horizontale X- und Y-Richtungen beweglichen Schlitten und einem daran festgelegten, in vertikale Z- Richtung beweglichen Stanzwerkzeug eines Stanzzylinders eines Stanzkopfes zur Bearbeitung eines Multikontaktsteckers mit unterschiedlicher Kontaktbelegung gemäß dem Oberbegriff des ersten Schutzanspruches. The invention relates to an automatic punching machine with a carriage movable at right angles in the horizontal X and Y directions and a punching tool of a punching cylinder of a punching head fixed to it, movable in the vertical Z direction, for processing a multi-contact plug with different contact assignments according to the preamble of the first protection claim.
Es ist eine Vorrichtung zum Ausbrechen und Entfernen von Abfallstanzteilen aus Nutzen oder Werkstoffbögen, insbesondere für Flachbettstanz- und/ oder Prägeautomaten bekannt, DE 196 48 952 C1 , die eine Vielzahl von Ausbrechnadeln aufweisen, die an exakt vorbestimmten Positionen des Stanzwerkzeuges angeordnet sind. A device for breaking out and removing waste punched parts from panels or sheets of material, in particular for flat bed punching and / or embossing machines, is known, DE 196 48 952 C1, which has a plurality of breaking needles which are arranged at precisely predetermined positions on the punching tool.
Nachteilig an einer solchen Vorrichtung ist es, dass zur Variation des Werkstückes separate Stanzwerkzeuge bzw. Matrizen mit unterschiedlich angeordneten Ausbrechnadeln vorgehalten werden müssen, was sehr unwirtschaftlich ist und bei einer gewünschten Variation eine Unterbrechung des Betriebes zum Umbau der Stanzwerkzeuge erfordert. A disadvantage of such a device is that separate punching tools or matrices with differently arranged stripping needles have to be kept available to vary the workpiece, which is very uneconomical and requires an interruption of operation to convert the punching tools if a variation is desired.
Aufgabe der Erfindung ist es, einen Stanzautomaten zur Verfügung zu stellen, der ohne eine solche Unterbrechung arbeiten kann und dadurch eine Vielzahl von verschiedenen Werkstücken bearbeiten kann, ohne dass hierzu die Produktion unterbrochen und der Stanzautomat umgebaut werden muss. The object of the invention is to provide an automatic punching machine which can work without such an interruption and can thereby process a large number of different workpieces without the production having to be interrupted and the automatic punching machine converted.
Die Lösung dieser Aufgabe ergibt sich in Verbindung mit den Merkmalen des Oberbegriffes erfindungsgemäß zusammen mit dem kennzeichnenden Teil des ersten Schutzanspruches dadurch, dass das Stanzwerkzeug aus einer einzelnen Stanznadel besteht. The solution to this problem results in connection with the features of the preamble according to the invention together with the characterizing part of the first protection claim in that the punching tool consists of a single punch needle.
Mit dem erfinderischen Stanzautomaten lassen sich demnach sog. Multi ko ntaktstecker mit unterschiedlicher Kontaktbelegung bearbeiten, ohne dass für eine Variation der
Kontaktbelegung eine spezielle Stempelmatrize in einen Stanzautomaten eingebaut werden müsste, da die einzelne Stanznadel die benötigten Kavitäten an allen vorgesehen Orten von den sie verschließenden Pins freistanzen kann. Ein Austausch von Stanzmatrizen kann demnach vollständig entfallen, sodass auch keine Betriebsunterbrechungen beim Wechsel von zu bearbeitenden Werkstücken mehr auftreten. With the punching machine according to the invention, so-called multi-contact plugs with different contact assignments can therefore be processed without the need for a variation of the Contact assignment a special stamp die would have to be built into an automatic punching machine, since the individual punch needle can punch the required cavities free from the pins that close them at all intended locations. An exchange of punching dies can therefore be completely omitted, so that there are no longer any operational interruptions when changing workpieces to be processed.
Weitere vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich mit und in Kombination aus den Unteransprüchen. Further advantageous embodiments of the subject matter of the invention emerge with and in combination from the subclaims.
Gemäß einer besonders bevorzugten Ausführungsform der Erfindung weist die Stanznadel eine Querschnittsform auf, die dem Ausstoßquerschnitt einer Kavität eines Multikontaktsteckers entspricht, sodass die Stanznadel die die Kavitäten verschließenden Pins nacheinander an den erforderlichen Orten des Multikontaktsteckers herausstanzen kann, wobei es diese Ausführungsform der Erfindung erlaubt, sehr genaue Ausstoßquerschnitte zu verwirklichen, die Toleranzen der Abmessungen von nur wenigen 1/100 mm aufweisen. According to a particularly preferred embodiment of the invention, the punch needle has a cross-sectional shape that corresponds to the ejection cross-section of a cavity of a multi-contact plug, so that the punch needle can punch out the pins closing the cavities one after the other at the required locations of the multi-contact plug, this embodiment of the invention very much to realize precise discharge cross-sections that have dimensional tolerances of only a few 1/100 mm.
Die Stanznadel ist bevorzugt in einem Stanzkolben gelagert, der mit einer vertikal verlaufenden Ausnehmung, wie etwa einer Durchgangsausnehmung in Form eines Langloches, mit mindestens einer vertikal verlaufenden Innenwandung ausgestattet ist. Im Stanzkopf ist ein mit der Innenwandung der Ausnehmung korrespondierender horizontaler Exzenterstift mit einer radialen Exzenterfläche um seine Horizontalachse drehbar gelagert, der sich in oder durch die Ausnehmung hinein oder hindurch erstreckt, wobei seine Exzenterfläche an die Innenwandung der Ausnehmung anlegbar ausgebildet ist, um eine Verdrehung der Stanznadel um ihre Hochachse vollkommen auszuschließen und die geforderte Präzision zur Verfügung stellen zu können. The punch needle is preferably mounted in a punch piston which is equipped with a vertically extending recess, such as a through recess in the form of an elongated hole, with at least one vertically extending inner wall. In the punching head, a horizontal eccentric pin corresponding to the inner wall of the recess and having a radial eccentric surface is rotatably mounted about its horizontal axis, which extends into or through the recess, with its eccentric surface being designed such that it can be placed against the inner wall of the recess to allow rotation of the Punching needle to completely exclude its vertical axis and to be able to provide the required precision.
Entsprechend einer weiteren vorteilhaften Ausführungsform der Erfindung ist der Stanzautomat mit mindestens einem weiteren Stanzkopf mit einem separaten Stanzzylinder für jedes weitere Stanzwerkzeug ausgestattet, sodass der Stanzautomat mit im Querschnitt unterschiedlichen Stanznadeln als Stanzwerkzeugen ausgestattet werden
kann, die wechselweise in Betrieb oder außer Betrieb setzbar sind, sodass auch ein Multikontaktstecker mit mehreren unterschiedlichen Kavitätenquerschnitten unterbrechungsfrei bearbeitet werden kann. According to a further advantageous embodiment of the invention, the automatic punching machine is equipped with at least one further punching head with a separate punching cylinder for each further punching tool, so that the punching machine is equipped with punching needles of different cross-sections as punching tools that can be alternately put into operation or out of operation, so that a multi-contact plug with several different cavity cross-sections can also be processed without interruption.
Bevorzugterweise ist um die Stanznadel herum im Stanzkopf mindestens eine in Stanzrichtung nach unten gerichtete Ausblasdüse oder eine Ringdüse angeordnet, mit der um die Stanznadel herum ein Luftvorhang erzeugbar ist, der die ausgestanzten Pins sicher aus dem Werkstück herausbefördert, sodass diese den Produktionsablauf nicht behindern können. Preferably, around the punching needle in the punching head there is at least one blow-out nozzle pointing downwards in the punching direction or a ring nozzle, with which an air curtain can be generated around the punching needle, which safely transports the punched-out pins out of the workpiece so that they cannot hinder the production process.
Der Stanzkolben des Stanzautomaten kann dabei wahlfrei pneumatisch, hydraulisch oder mit anderen Fluidtechniken, wie z.B. mit Wasser, oder mechanisch oder mittels eines Linearantriebes angetrieben sein, sodass er universell einsetzbar ausgebildet ist. The punching piston of the automatic punching machine can optionally be pneumatic, hydraulic or with other fluid technologies, e.g. be driven with water, or mechanically or by means of a linear drive, so that it can be used universally.

Fig. 7 eine räumliche Teilansicht eines Multifunktionssteckers.
Der Stanzautomat besteht aus einer XY-Antriebseinheit 9 mit einem in X-Richtung beweglichen Schlitten 1 und einem in Y-Richtung beweglichen Schlitten 2, sowie aus einem daran angeordneten Stanzkopf 5 mit einem Stanzzylinder 4 in dem ein Stanzkolben 1 1 vertikal beweglich geführt ist, in dem wiederum an seinem vorderen Ende eine Stanznadel 7 leicht auswechselbar gelagert ist. Der Stanzautomat kann, wie in der Figur 2 dargestellt ist, mit einem Platzhalter 18 für einen zweiten Stanzkopf ausgestattet sein. 7 shows a three-dimensional partial view of a multifunction plug. The automatic punching machine consists of an XY drive unit 9 with a carriage 1 movable in the X direction and a carriage 2 movable in the Y direction, as well as a punching head 5 with a punching cylinder 4 arranged on it, in which a punching piston 1 1 is vertically movably guided, in which, in turn, a punch needle 7 is easily exchangeable at its front end. As shown in FIG. 2, the automatic punching machine can be equipped with a placeholder 18 for a second punching head.
Der Stanzkolben 1 1 weist eine vertikale Ausnehmung 12 auf, die hier als Durchgangslangloch ausgebildet ist und zueinander parallele Innenwandungen 13 aufweist, wobei sich ein Exzenterstift 14 horizontal durch den Stanzzylinder 4 erstreckt, der auch die Ausnehmung 12 im Stanzkolben 1 1 durchtritt, wobei seine radiale Exzenterfläche zumindest an einer Innenwandung 13 des Stanzkolbens 1 1 anlegbar ist, wodurch eine Verdrehung des Stanzkolbens 1 1 um seine vertikale Hochachse verhindert wird. The punching piston 1 1 has a vertical recess 12, which is designed here as a through hole and has inner walls 13 parallel to one another, an eccentric pin 14 extending horizontally through the punching cylinder 4, which also passes through the recess 12 in the punching piston 1 1, with its radial Eccentric surface can be placed at least on an inner wall 13 of the punching piston 1 1, whereby a rotation of the punching piston 1 1 about its vertical axis is prevented.
Im Bereich des Austritts des Stanzkolbens 1 1 aus dem Stanzzylinder 4 ist um den Stanzkolben 1 1 herum ein Luftring 1 7 angeordnet, der in vertikale Richtungen nach unten Ausblasdüsen 15 oder auch eine Ringdüse aufweist, die einen Luftmantel um die Stanznadel 7 herum erzeugen, sodass sichergestellt wird, dass ausgestanzte Pins 16 des zu erzeugenden Multikontaktsteckers 6 sicher in Stanzrichtung ausgetrieben werden und die entsprechenden Kavitäten 10 freigeben. In the area of the exit of the punching piston 1 1 from the punching cylinder 4, an air ring 1 7 is arranged around the punching piston 1 1, which has blow-out nozzles 15 in vertical directions downwards or also an annular nozzle that generates an air jacket around the punching needle 7 so that it is ensured that punched-out pins 16 of the multi-contact plug 6 to be produced are securely driven out in the punching direction and clear the corresponding cavities 10.
Eine Stanznadel 7 weist exakt den Querschnitt einer solchen Kavität 10 auf, sodass hochgenaue Ausstoßquerschnitte mit einer Toleranz von nur wenigen 1/100 mm erzeugbar sind. A punch needle 7 has exactly the cross section of such a cavity 10, so that highly precise ejection cross sections with a tolerance of only a few 1/100 mm can be produced.
Dort, wo später keine Kabelbelegung der Kavitäten 10 des Multikontaktsteckers 6 erfolgt, werden im Anschluss sog. Dichtmatten eingesetzt, um den Multi ko ntaktstecker 6 wasserdicht zu gestalten.
Where the cavities 10 of the multi-contact plug 6 are not later used by cables, what are known as sealing mats are then used to make the multi-contact plug 6 watertight.
