Abstract
Description
Die Erfindung betrifft ein Verfahren zur Anderung des Querschnitts eines stranggepreßten Profils.The invention relates to a method for changing the Cross section of an extruded profile.
Bisher wird der Querschnitt eines stranggepreßten Profils dadurch geändert, daß ein horizontaler Steg eines Winkelprofils gequetscht wird und dabei das ausweichende Material den Ver tikalsteg nach oben drückt.So far, the cross section of an extruded profile changed in that a horizontal web of an angle profile is squeezed and the evasive material Ver tikalsteg pushes up.
Nachteilig an dieser Verfahrensweise ist, daß eine große Querschnittsveringerung des gequetschten horizontalen Steges des Al-Profils auftritt, und daß die statische Festigkeit des Pro fils verringert wird.The disadvantage of this procedure is that a large Cross-sectional reduction of the squeezed horizontal web of the Al profile occurs and that the static strength of the Pro fils is reduced.
Darüberhinaus können hierdurch Änderungen am Querschnitt nur an den Profilenden durchgeführt werden.In addition, changes to the cross section can be made only be carried out at the profile ends.
Während stranggepreßte Profile, insbesondere Aluminium profile, aufgrund der diesbezüglichen speziellen Preßverfahren gleichen Profilquerschnitt über die gesamte Stranglänge besit zen, werden dennoch häufig Änderungen des Querschnitts eines solchen stranggepreßten Profils oder Profilteils notwendig. While extruded profiles, especially aluminum profiles, due to the special pressing process in this regard have the same profile cross-section over the entire length of the strand zen, changes in the cross-section of a such extruded profile or profile part necessary.
Erfindungsgemäß wird deshalb ein Verfahren zur Änderung des Querschnitts eines stranggepreßten Profils vorgeschlagen, das dadurch gekennzeichnet ist, daß man das zu ändernde Profil in eine Matrize einlegt, die der Außenkontur des geänderten Profil querschnitts entspricht, und daß man durch kontinuierliches punktförmiges Andrücken der Innenkontur des zu ändernden Profils an die Matrize den Querschnitt verformt. Weitere bevorzugte Ausführungsformen des erfindungsgemäßen Verfahrens sind in den Ansprüchen 2 bis 6 wiedergegeben.According to the invention, therefore, a method for changing the Cross section of an extruded profile proposed that is characterized in that the profile to be changed in insert a die that corresponds to the outer contour of the modified profile cross-section corresponds, and that one by continuous punctiform pressing of the inner contour of the profile to be changed the cross section deformed to the die. More preferred Embodiments of the method according to the invention are in the Claims 2 to 6 reproduced.
Das erfindungsgemäße Verfahren wird anhand der beiliegenden Fig. 1 bis 3 näher erläutert.The method according to the invention is explained in more detail with reference to the accompanying FIGS. 1 to 3.
Fig. 1 ist die schematische Aufsicht auf ein stranggepreß tes Al-Winkelprofil mit einem horizontalen Schenkel 2 und einem vertikalen Schenkel 1 (Fig. 1a). Fig. 1 is a schematic plan view of an extruded Al angle profile with a horizontal leg 2 and a vertical leg 1 ( Fig. 1a).
Fig. 1b gibt den Querschnitt dieses Profils wieder, wobei die Bezugszeichen der Fig. 1a entsprechen. Fig. 1b shows the cross section of this profile, the reference numerals corresponding to Fig. 1a.
Dieses Profil soll zu dem Profil gemäß Fig. 2a verformt werden, wobei diese Verformung zum einen in der Verbreiterung der Grundplatte 2 gemäß rechter Hälfte der Fig. 2a und der Verformung der Außenkontur durch die S-förmige Verformung 3 der aufgebogenen Kante 1 besteht. Diese Art der Verformung soll schematisch durch die geänderte Querschnittswiedergabe gemäß Fig. 2b dargestellt sein.This profile is to be deformed to the profile according to FIG. 2 a, this deformation consisting in the widening of the base plate 2 according to the right half of FIG. 2 a and the deformation of the outer contour by the S-shaped deformation 3 of the bent edge 1 . This type of deformation is to be represented schematically by the changed cross-sectional rendering according to FIG. 2b.
Erfindungsgemäß wird das Profil 1/2 gemäß Fig. 1a in eine Matrize 6 gemäß Fig. 3a eingelegt, die eine Anlagefläche 7 aufweist, deren Ausgestaltung der gewünschten Außenkontur des geanderten Profilquerschnitts gemäß Fig. 2a entspricht.According to the invention, the profile 1/2 according to FIG. 1a is inserted into a die 6 according to FIG. 3a, which has a contact surface 7 , the design of which corresponds to the desired outer contour of the changed profile cross section according to FIG. 2a.
Vor Beginn des Verfahrens liegt die aufgebogene Kante 1 gemäß Fig. 1a nur im linken Bereich der Matrize 6 gemäß Fig. 3a an.Before the start of the method, the bent edge 1 according to FIG. 1 a only rests in the left area of the die 6 according to FIG. 3 a.
Durch punktförmiges Einwirken der Rolle 4 auf die Innenkon tur der Aufbiegung 1 im Berührungspunkt 5 wird durch Abrollen der Rolle 4 in Pfeilrichtung nach rechts unter gleichzeitigem Anpressen in Richtung auf die Matrize 6 hin die Verformung der Außenkontur des stranggepreßten Profils 1/2 unter teilweiser Verbreiterung der Grundplatte 2 erzielt. In Fig. 3b wird die verfahrensgemäße Vorrichtung aus Matrize 6 und Rolle 4 schema tisch im Querschnitt wiedergegeben, wobei in der Ausnehmung zwischen Matrize und Rolle das im Querschnitt zu verändernde Ausgangsprofil anzuordnen ist, und wobei die gestrichelte Linie innerhalb der Matrize 6 die Verformung der Außenkontur des Ausgangsprofils symbolisieren soll.By punctiform action of the roller 4 on the Innenkon structure of the bend 1 at the point of contact 5 by rolling the roller 4 in the direction of the arrow to the right while simultaneously pressing in the direction of the die 6 towards the deformation of the outer contour of the extruded profile 1/2 with partial widening of the Base plate 2 achieved. In Fig. 3b, the device according to the method of die 6 and roller 4 is shown schematically in cross-section, the cross-section of the starting profile to be changed being arranged in the recess between the die and roller, and the dashed line inside the die 6 representing the deformation of the outer contour symbolize the initial profile.
Durch den Verformungsvorgang werden beide Schenkel 1, 2 des Ausgangsprofils zumindestens im Bereich der Anderung gedehnt. Diese Dehnung führt bei beiden Schenkeln zu einer Verringerung der Profildicke. Um ein Reißen des Profils zu vermeiden, werden bevorzugt Matrize und Rolle im Ubergang der beiden Schenkel abgerundet, wobei bevorzugt die beiden Schenkel 1, 2 auch selbst nicht rechtwinkelig, sondern abgerundet ineinander übergehen.Due to the deformation process, both legs 1 , 2 of the initial profile are stretched at least in the area of the change. This expansion leads to a reduction in the profile thickness in both legs. In order to avoid tearing of the profile, the die and the roller are preferably rounded in the transition between the two legs, the two legs 1 , 2 preferably also merging into one another not at right angles, but in a rounded manner.
