Description
Die Erfindung betrifft ein Verfahren zum Strangpressen und eine Strangpreßanlage, insbesondere zum Herstellen von gekrümmten Strangpreßprodukten, wobei das Preßprodukt in einer einem Gegenholm der Strangpreßanlage vorgelagerten Matrize geformt und anschließend durch Einwirken äußerer Kräfte gekrümmt bzw. abgebogen wird.The invention relates to a method for extruding and an extrusion press, in particular for producing curved extruded products, wherein the Preßprodukt in a counterhull of the extrusion die upstream template formed and then curved by the action of external forces or is bent.
Zur Herstellung von in verschiedensten industriellen Bereichen zu unterschiedlichsten Zwecken benötigten gekrümmten bzw. gebogenen Strangpressprofilen, die vorrangig aus Aluminium und Magnesiumlegierungen bestehen, ist es für das Strangpressen von Hohlprodukten mit großen Wanddickenunterschieden durch die EP 0 706 843 B1 bekanntgeworden, in einem solch bestimmten Abstand vom Matritzenaustrittsende bzw. Gegenholm mit einem Druckmittel eine Kraft auf den Strang auszuüben, daß sich eine Rückwirkung auf das in der Strangpressmatritze geformte Profil ergibt. Bei dem Druckmittel kann es sich um eine Andrückrolle, eine eine Querkraft erzeugende Gleitfläche oder einen Rollenkäfig handeln. Ganz gleich jedoch, welches Druckaufbringungsmittel eingesetzt wird, so muß der für die Rückwirkung bestimmte Abstand eingehalten werden, damit das Strangpressprodukt gleichzeitig mit oder unmittelbar nach dem formgebenden Strangpressvorgang beim Abbiegen bzw. Krümmen derart beeinflußt wird, daß die in der Strangpressmatritze gebildeten Werkstückquerschnitte nicht parallel zueinander aus der Matritze austreten, sondern in einem Winkel zueinander stehen.For the production of various industrial sectors too different purposes needed curved or curved Extruded profiles, primarily made of aluminum and magnesium alloys exist, it is for the extrusion of hollow products with large ones Wall thickness differences have become known from EP 0 706 843 B1, in one Such specific distance from the Matrizenaustrittsende or counter-spar with a Pressure medium to exert a force on the strand, that has a retroactive effect on the profile formed in the extrusion die results. The pressure medium may be around a pressure roller, a lateral force generating sliding surface or a Roll cage act. No matter which pressure application agent is used, so the specified for the reaction distance must be respected so that the extruded product can be used simultaneously with or immediately after shaping extruding process during bending or bending influenced in such a way is that the workpiece cross sections formed in the extrusion die not parallel to each other from the die emerge, but at an angle to each other stand.
Zum Strangpressen gekrümmter Stränge ist es durch die DE 197 16 292 A1 bekanntgeworden, zwischen der Matrize und dem Querholm der Strangpresse eine zusätzliche Halterung vorzusehen, die eine seitliche, nach unten weisende Öffnung besitzt, durch die der gekrümmte Strang vor dem Querholm angezogen werden kann. Zur Biegung des Stranges sind der eigentlichen Matrize nachfolgend in, der Halterung mehrere Matrizenelemente angeordnet, die quer zur Pressrichtung verschiebbar sind und durch ihre Einwirkung auf den Strang dessen Krümmung und Umlenkung durch die seitliche Öffnung der Halterung bewirken.For extruding curved strands, it is known from DE 197 16 292 A1 become known, between the die and the cross member of the extruder a provide additional bracket, which has a side, downwardly facing opening possesses, by which the curved strand in front of the transverse spar are tightened can. To bend the strand are the actual matrix below in, the Holding several die elements arranged, which are transverse to the pressing direction are displaceable and by their action on the strand whose curvature and Deflection caused by the lateral opening of the holder.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Strangpresse der eingangs genannten Art zu schaffen, die es mit einfachen Mitteln erlauben, Preßprodukte mit einer breiten Palette von Biegeradien herzustellen.The invention is based on the object, a method and an extruder of the type mentioned above, which allow it by simple means Produce pressed products with a wide range of bending radii.
Diese Aufgabe wird mit einem Verfahren erfindungsgemäß dadurch gelöst, daß an das in den Gegenholm mit gerader Auspreßrichtung eintretende Preßprodukt die äußere Kraft im Gegenholm zur Einwirkung gebracht und an dem Pressprodukt mindestens ein Biegeradius ausgebildet wird. Indem somit der Ort des Geschehens der Bildung von Krümmungen bzw. Radien unmittelbar nach Eintritt des Stranges in den Gegenholm dort schon gleich vorgesehen wird, lassen sich - ohne Notwendigkeit einer Vorkrümmung bereits in der Matrize - kleinste Radien erreichen, weil eine sofortige Ab- bzw. Auslenkung des Stranges möglich ist.This object is achieved by a method according to the invention in that the entering in the counter-spar with a straight Auspreßrichtung press product the external force brought into action in the counter-spar and on the pressed product at least one bending radius is formed. By thus the place of the happening the formation of curves or radii immediately after entry of the strand in the counterweight is already provided there, can be - without necessity a pre-curvature already in the matrix - smallest radii reach because of a Immediate deflection or deflection of the strand is possible.
Nach einem Vorschlag der Erfindung können sich Preßphasen mit grader Auspressung des Stranges und solche mit Biegeeinwirkung auf den Strang zeitlich abwechseln. Dies erlaubt es, beispielsweise Fahrzeugrahmenteile herzustellen und dabei vorteilhaft auch unterschiedliche Biegeradien anzubringen. Nach dem Pressen eines geraden Strangabschnitts braucht der Strang zur Abbiegung lediglich mit einer mehr oder weniger großen äußeren Kraft abgelenkt zu werden, so daß ein erster Biegeradius vorliegt, wobei der Strang danach über einen gewünschten Abschnitt erneut gerade ausgepreßt werden kann, bevor dann ein weiterer Biegeradius ausgebildet wird. Der zeitliche Ablauf von geradem Auspreßvorgang und Krafteinwirkung zur Abbiegung bzw. Krümmung des Stranges kann hierbei mittels des übergeordneten Rechners der Strangpreßanlage gesteuert werden.According to a proposal of the invention, pressing phases with grader Extrusion of the strand and those with bending action on the strand in time alternate. This makes it possible to produce, for example, vehicle frame parts and advantageous to install different bending radii. After pressing of a straight strand section of the strand needs to turn only with a more or less great external force to be distracted so that a first Bending radius is present, the strand then over a desired section can be pressed again just before then another bending radius is trained. The timing of straight extrusion and Force for bending or curvature of the strand can hereby means the parent computer of the extrusion press are controlled.
Eine Strangpreßanlage zur Lösung der der Erfindung zugrundeliegenden Aufgabe weist einen Gegenholm auf, der mit einer seitlichen, sich quer zur geraden Auspreßrichtung erstreckenden Holmöffnung ausgebildet ist, die ein integriertes Stellglied/aufweist. Der Holm braucht sich nur zu einer Holmseite hin zu öffnen und zur Beaufschlagung des Preßproduktes mit der äußeren Kraft schafft den benötigten Freiraum, um den Strang schon gleich im Gegenholm abzulenken und mit dem gewünschten Biegeradius zu versehen. Bei dem in die seitliche Öffnung integrierten Stellglied kann es sich beispielsweise um einen druckmittelbeaufschlagten Zylinder oder dergleichen mit einem Andrückkopf an seinem von der gegenüberliegenden Seite her in die Holmöffnung eintauchenden Kolbenstangenende handeln. Um die gewünschten Abbiegungen bzw. Strangkrümmungen vorzunehmen, reichen insbesondere beim Strangpressen von Aluminiumprofilen schon geringe Krafteinwirkungen aus. An extrusion press for solving the problem underlying the invention has a counter-spar, with a lateral, transverse to the straight Auspreßrichtung extending spar opening is formed, which is an integrated / Comprising actuator. The spar only needs to open to a side of the spar and for acting on the press product with the external force creates the required clearance, around the strand right in the backstop distract and provide with the desired bending radius. In the in the lateral opening integrated actuator may be, for example, a druckmittelbeaufschlagten cylinder or the like with a pressure head on his dipping from the opposite side in the spar opening Piston rod end act. To the desired bends or Strand curvatures are sufficient, especially in the extrusion of Aluminum profiles already low force effects.
Wenn gemäß einem Vorschlag der Erfindung der Gegenholm in Relation zur Holmbreite mehrfach höher und vorteilhaft in Zwei-Säulen-Bauweise ausgeführt ist, läßt sich eine sehr breite Palette von unterschiedlichen und insbesondere sehr kleinen Biegeradien erzeugen. Denn aufgrund des eine überdurchschnittliche Höhe aufweisenden, d.h. lang und schmal bauenden Gegenholms kann nach einer ersten Abbiegung dann schon gleich wieder eine nächste Krümmung erzeugt werden, sobald der Krümmungsabschnitt des Stranges den bei dieser Bauweise nur kurzen Weg bis zum Austritt aus der seitlichen Öffnung zurückgelegt hat.If, according to a proposal of the invention, the counter-spar in relation to Holmbreite several times higher and advantageous in two-column design is executed, can be a very wide range of different and especially very generate small bending radii. Because of the above average height having, i. long and narrow-building Gegenholms can after a first Turn right then a next bend will be generated again, as soon as the curvature portion of the strand in this construction only short Path has traveled back to the exit from the side opening.
Nach einer Ausgestaltung der Erfindung ist dem Stellglied ein Gegenhalter zugeordnet. Als Gegenhalter, der unterhalb der Paßlinie des Stranges angeordnet ist, eignet sich zweckmäßig eine Rolle oder ein sonstiges, dem Strang mit einer Rundung zugewandtes Gegenhalterelement. Auch dieses Gegenhalter-Anbauelement unterstützt es, durch einen mehr oder weniger großen Durchmesser bzw. Radius der dem Strang anliegenden Rundung den herzustellenden Biegeradius am Strang zu beeinflussen.According to one embodiment of the invention, the actuator is a counter-holder assigned. As an anvil, which is arranged below the pass line of the strand is suitably, a role or another, the strand with a Rounding facing counter-element. Also this counterholder attachment supports it, by a more or less large diameter or radius of the strand adjacent rounding the bending radius to be produced to influence the strand.

Von einer als solche hinlänglich bekannten Strangpreßanlage 1 ist in den Figuren im
wesentlichen lediglich der Gegenholm 2 bzw. 102 und 202 (vgl. die Fig. 6a, 6b und
7a, 7b) dargestellt. Diese sind mit einer seitlichen Öffnung 3 bzw. 103 und 203
ausgebildet, die sich jeweils quer zur geraden Auspreßrichtung 4 zu einer Holmseite
hin erstreckt.From an as such well-known extrusion 1 is shown in the figures in the
essentially only the
Aus den Fig. 1 bis 5 ist zu entnehmen, daß der seitlichen Holmöffnung 3 ein mit einer
Kolbenstange 5 durch den Gegenholm 2 bis in die seitliche Holmöffnung 3
reichendes Stellglied 6 zugeordnet ist. Dieses wird mit einem Andrückkopf 7 an den
Strang 8 angestellt, der über einen einlaufseitig auf dem Gegenholm 2 aufliegenden
Werkzeugträger 9 mit Druckplatte einläuft. Ein im Gegenholm 2 unterhalb der
Durchlauf- bzw. Paßlinie des Stranges 8 angeordneter Gegenhalter 10 in Form einer
Rolle wirkt dem Stellglied 6 entgegen, wenn dieses mit ihrer Kolbenstange 5 und
dem Andrückkopf 7 an den Strang 8 angestellt wird.From FIGS. 1 to 5 it can be seen that the lateral spar opening 3 a with a
Piston
Der Strang 8 wird gemäß den Fig. 1 und 2 zunächst normal, d.h. gerade ausgepreßt,
bis ein voreilender Strangabschnitt 8a (vgl. Fig. 2) in Auspreßrichtung 4 mit einer
gewünschten Länge durchgelaufen ist. Wenn dann zu diesem Zeitpunkt das
Stellglied 6 gegen den Strang 8 beaufschlagt wird, wird der Strang mit einer
Krümmung bzw. einem Biegeradius 11 versehen (vgl. Fig. 3). Der Strang 8 bzw. 8a
legt sich hierbei auf einen Tisch 12 des Auslaufs der Strangpreßanlage 1. Durch ein
Wechselspiel mit geradem Auspreßvorgang und Beaufschlagung des Stellgliedes 6
zur Ausbildung einer Krümmung wird nach dem Auspressen eines geraden
Strangabschnitts 8b (vgl. Fig. 4) an dem selben Strang 8 ein in Fig. 5 gezeigter
weiterer Biegeradius 11 ausgebildet, so daß sich auf diese Weise auch
Strangpreßprodukte mit mehr als einer Krümmung an dem selben Strang 8
herstellen lassen.The
Die Gegenholme 102 bzw. 202 gemäß den Fig. 6a, 6b bzw. 7a, 7b zeichnen sich
durch eine sehr lange und schmale Bauweise mit einer überdurchschnittlichen
Holmhöhe aus. Die Gegenholme 102 bzw. 202 sind im Ausführungsbeispiel in einer
Bauweise mit zwei Säulen 13a, bzw. 13b ausgeführt. Die seitliche Holmöffnung 103
bzw. 203 ist aufgrund der schmalen Bauweise bis zum seitlichen Öffnungsende nur
sehr kurz (vgl. die Fig. 6b und 7b), so daß aufeinanderfolgende Biegeradien an
denselben Strangpreßprodukt in kürzerer Abfolge ausgebildet werden können. Zur
gleichwohl unverändert guten Aufnahme der Strangpreßkräfte sind die Gegenholme
102 bzw. 202 an ihren von der seitlichen Holmöffnung 103 bzw. 203 abgewandten
Seite durch eine Materialausbauchung 14 verstärkt. Die den Strang abbiegenden
Stellmittel sind für die Gegenholme 102 bzw. 202 in den Figuren nicht gezeigt.
Während beim Gegenholm 102 die Druckplatte des Werkzeugträgers 9 (vgl. Fig. 1)
in eine Holmausnehmung 15 eintaucht, liegt die strichpunktiert verdeutlichte
Druckplatte 16 bei der Ausführung nach den Fig. 7a, 7b einlaufseitig auf dem
Gegenholm 202 auf. Die Tiefe der seitlichen Holmöffnung 203 in Auspreßrichtung 4
kann gegenüber der Variante nach Fig. 6a bei ansonsten gleichen
Holmabmessungen entsprechend größer ausgelegt werden.The
Allen Ausführungen mit einer seitlichen Holmöffnung des Gegenholms ist gemeinsam, daß sie das Pressen von Strängen mit beliebigen, unterschiedlichen Biegeradien bzw. Krümmungen schon gleich im Gegenholm erlauben.All versions with a side spar opening of the Gegenholms is in common that they are the pressing of strands with any, different Bending radii or curvatures already allow in the counter-spar.
