BeschreibungDescription
Die vorliegende Erfindung betrifft eine Tankplatte für einen Tank eines Extrusionswerkzeuges zum Extrudieren eines Profilstranges.The present invention relates to a tank plate for a tank of an extrusion tool for extruding a profile strand.
Ein Extrusionswerkzeug zum Extrudieren eines Profilstranges besteht üblicherweise aus drei Teilen, und zwar einer Extrusionsdüse, einer Kalibriereinrichtung und einem Tank. Der Tank dient dazu, den Profilstrang nach Verlassen der Extrusionsdüse und Durchlaufen der Kalibriereinrichtung zu kühlen, beispielsweise mittels eines Wassernebels. Zu diesem Zweck wird der Profiistrang in Längsrichtung durch den langgestreckten Tank geführt. Der Tank ist mit einer größeren Anzahl von Tankplatten versehen, die querverlaufend zu der Bewegungsrichtung des Profilstranges angeordnet sind und jeweils ein Durchgangsloch haben. Die Form der Durchgangslöcher entspricht im wesentlichen dem Profil des Profilstranges, um den Profilstrang beim Durchlaufen des Tanks zu fuhren und in Form zu halten.An extrusion tool for extruding a profile strand usually consists of three parts, namely an extrusion nozzle, a calibration device and a tank. The tank is used to cool the profile strand after it leaves the extrusion nozzle and passes through the calibration device, for example by means of a water mist. For this purpose, the profile strand is guided lengthwise through the elongated tank. The tank is provided with a large number of tank plates that are arranged transversely to the direction of movement of the profile strand and each have a through hole. The shape of the through holes essentially corresponds to the profile of the profile strand in order to guide the profile strand as it passes through the tank and keep it in shape.
Die Tankplatten bestehen üblicherweise aus Aluminium, Messing oder Werkzeugstahl. Wie sich gezeigt hat, tritt in den Tankplatten an den Lochrändern ein sehr hoher Verschleiß auf, der von der Gleitreibung zwischen dem Profilstrang und den Lochrändern herrührt. Die Tankplatten haben daher eine relativ kurze Lebensdauer und müssen somit entsprechend häufig ausgewechselt oder ausgebessert werden.The tank plates are usually made of aluminum, brass or tool steel. As has been shown, the edges of the holes in the tank plates are subject to very high levels of wear, which is caused by the sliding friction between the profile strand and the edges of the holes. The tank plates therefore have a relatively short lifespan and therefore have to be replaced or repaired frequently.
Der Erfindung liegt die Aufgabe zugrunde, eine derartige Tankplatte so weiterzubilden, daß die Lebensdauer der Tankplatte bei möglichst geringem Aufwand verlängert wird.The invention is based on the object of developing such a tank plate in such a way that the service life of the tank plate is extended with the least possible effort.
Diese Aufgabe wird durch die im Anspruch 1 gekennzeichnet Erfindung gelöst. This object is achieved by the invention characterized in claim 1.
Die Erfindung geht von der Erkenntnis aus, daß ein erhöhter Verschleiß nur an bestimmten Stellen des Lochumfanges der Tankplatte auftritt. Erfindungsgemäß werden an diesen Stellen verschleißfeste Einsätze vorgesehen. Es ist somit nicht erforderlich, die gesamte Tankplatte aus einem verschleißfesten Material herzustellen oder mit einem verschleißfesten Überzug zu versehen. Dennoch läßt sich durchThe invention is based on the knowledge that increased wear only occurs at certain points on the circumference of the hole in the tank plate. According to the invention, wear-resistant inserts are provided at these points. It is therefore not necessary to manufacture the entire tank plate from a wear-resistant material or to provide it with a wear-resistant coating. Nevertheless,
die Erfindung die Lebensdauer der Tankplatten um ein mehrfaches erhöhen, wie sich bereits anhand von Versuchen feststellen ließ.The invention increases the service life of the tank plates several times over, as has already been shown by tests.
Die verschleißfesten Einsätze, die beispielsweise aus Sintermetall, Sinterkeramik, gehärtetem Stahl oder beschichtetem Stahl bestehen, lassen sich in einfacher Weise durch einen Preßsitz, eine Klebe- oder Lötverbindung oder durch eine Schraubverbindung an den entsprechenden Stellen der Tankplatte befestigen. Diese Lösung zeichnet sich durch niedrige Kosten und einen geringen Aufwand aus.The wear-resistant inserts, which are made of sintered metal, sintered ceramic, hardened steel or coated steel, for example, can be easily attached to the corresponding points on the tank plate using a press fit, an adhesive or solder connection or a screw connection. This solution is characterized by low costs and little effort.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Further advantageous embodiments of the invention are specified in the subclaims.
Anhand der Zeichnungen wird ein Ausführungsbeispiel der Erfindung näher erläutert. Es zeigt:An embodiment of the invention is explained in more detail using the drawings. It shows:
Fig. 1 einen Querschnitt durch einen Tank eines Extrusionswerkzeu-Fig. 1 shows a cross section through a tank of an extrusion tool
ges mit einer Tankplatte;total with a tank plate;
Fig. 2 eine vergrößerte Darstellung der Tankplatte in Fig. 1.Fig. 2 is an enlarged view of the tank plate in Fig. 1.
Wie die Querschnittsansicht der Fig. 1 zeigt, besteht ein Tank 10 eines im übrigen nicht dargestellten Extrusionswerkzeuges zum Extrudieren eines Profilstranges aus einem Gehäuse 12, das aus mehreren plattenförmigen Teilen zusammengesetzt ist und auf einer Grundplatte 14 ruht. Der Tank 10 ist mit Leitungsanschlüssen 16 versehen, mit deren Hilfe beispielsweise ein Wassernebel im Inneren des Tanks 10 erzeugt werden kann, um den den Tank durchlaufenden Profilstrang (nicht gezeigt) zu kühlen.As the cross-sectional view of Fig. 1 shows, a tank 10 of an extrusion tool (not shown) for extruding a profile strand consists of a housing 12, which is composed of several plate-shaped parts and rests on a base plate 14. The tank 10 is provided with line connections 16, with the help of which, for example, a water mist can be generated inside the tank 10 in order to cool the profile strand passing through the tank (not shown).
Die Bewegungsrichtung des Profiistranges beim Durchlaufen des Tanks 10 steht auf der Zeichnungsebene der Fig. 1 senkrecht. Der Tank 10 hat somit eine senkrecht zur Zeichnungsebene der Fig. 1 verlaufende Längserstreckung, wobei in Längsrichtung des Tanks eine größere Anzahl (beispielsweise 15) von zueinander beabstandeten Tankplatten eingesetzt sind, die dazu dienen, den Profilstrang beim Durchlaufen des Tanks zu führen und in Form zu halten.The direction of movement of the profile strand as it passes through the tank 10 is perpendicular to the drawing plane of Fig. 1. The tank 10 thus has a longitudinal extension that runs perpendicular to the drawing plane of Fig. 1, with a large number (for example 15) of spaced-apart tank plates being used in the longitudinal direction of the tank, which serve to guide the profile strand as it passes through the tank and to keep it in shape.
In Fig. 1 ist eine derartige Tankplatte 20 zu sehen, die in nicht näher dargestellter Weise in das Gehäuse 12 des Tanks 10 eingesetzt ist. Die Tankplatte 20, die aus mehreren Plattenteilen zusammengesetzt ist (siehe auch Fig. 2), hat beispiels-In Fig. 1, such a tank plate 20 can be seen, which is inserted in a manner not shown in detail into the housing 12 of the tank 10. The tank plate 20, which is composed of several plate parts (see also Fig. 2), has, for example,
weise eine Dicke zwischen 5 und 30 mm. Sie ist mit einem Durchgangsloch 22 versehen, dessen Form ungefähr dem Profil des Profiistranges entspricht. Genauer gesagt, hat das Durchgangsloch 22 eine etwas größere Querschnittsfläche als der Profilstrang, so daß der Profilstrang bei seiner Bewegung durch die Tankplatte 20 hindurch nur an einigen Stellen des Lochrandes an der Halteplatte gleitend anliegt.preferably has a thickness of between 5 and 30 mm. It is provided with a through hole 22, the shape of which corresponds approximately to the profile of the profile strand. More precisely, the through hole 22 has a slightly larger cross-sectional area than the profile strand, so that the profile strand only slides against the retaining plate at some points on the edge of the hole when it moves through the tank plate 20.
An diesen Stellen sind verschleißfeste Einsätze 24, 26 vorgesehen. Die verschleißfesten Einsätze 24,26 sind vorzugsweise in die Tankplatte 20 eingepreßt, können aber auch in anderer Weise an der Tankplatte 20 befestigt werden, beispielsweise durch eine Klebe-, Lot- oder Schraubverbindung. Die Einsätze 24, 26 bestehen vorzugsweise aus Sintermetall, können jedoch aus einem anderen verschleißfesten Material wie z.B. Sinterkeramik, gehärtetem Stahl oder beschichtetem Stahl bestehen.Wear-resistant inserts 24, 26 are provided at these points. The wear-resistant inserts 24, 26 are preferably pressed into the tank plate 20, but can also be attached to the tank plate 20 in another way, for example by means of an adhesive, solder or screw connection. The inserts 24, 26 are preferably made of sintered metal, but can be made of another wear-resistant material such as sintered ceramic, hardened steel or coated steel.
Bei dem dargestellten Ausführungsbeispiel hat der Profilstrang und somit auch das Durchgangsloch ungefähr die Form eines T, wobei das T, wie in der Zeichnung zu sehen ist, mit Vor- und Rücksprüngen 28 versehen ist. Bei dem dargestellten Ausführungsbeispiel sind in dem Quersteg des T zwei Einsätze 24 und im unteren Bereich des senkrechten Stegs des T zwei Einsätze 26 vorgesehen. Die oberen Einsätze 24, die einen L-förmigen Querschnitt haben, sind so angeordnet, daß sie jeweils eine nach oben weisende wie auch senkrecht verlaufende Anlagefläche haben, während die unteren Einsätze 26 jeweils eine nach unten weisende Anlagefläche haben. Diese Anordnung und Ausgestaltung der Einsätze 24 und 26 wird natürlich so gewählt, daß sie den Profilstrang in der Weise abstützen und führen, daß sie möglichst die gesamten Anpreß- und Reibkräfte, die von dem Profilstrang auf die Tankplatte ausgeübt werden, aufnehmen, um den Verschleiß der Tankplatte zu minimieren.In the embodiment shown, the profile strand and thus also the through hole have approximately the shape of a T, whereby the T, as can be seen in the drawing, is provided with projections and recesses 28. In the embodiment shown, two inserts 24 are provided in the transverse web of the T and two inserts 26 are provided in the lower area of the vertical web of the T. The upper inserts 24, which have an L-shaped cross section, are arranged in such a way that they each have an upwardly facing and vertically running contact surface, while the lower inserts 26 each have a downwardly facing contact surface. This arrangement and design of the inserts 24 and 26 is of course chosen so that they support and guide the profile strand in such a way that they absorb as much of the contact and friction forces as possible that are exerted by the profile strand on the tank plate in order to minimize wear on the tank plate.
