Description

Die Herstellung von Schüsseln für Kraftfahrzeugräder wird in der Regel aus Platinen vorgenommen, die wiederum aus Bandmaterial oder Breitflachstahl ausgestanzt oder ausgebrannt werden. Bei dieser Herstellungsart ist der Materialabfall sehr hoch und liegt bei ca. 35 bis 40%.The production of bowls for motor vehicle wheels is usually made of boards, which in turn are punched out or burned out of strip material or wide flat steel. In this production, the material waste is very high and is about 35 to 40%.

Um diese sehr hohe Materialverschwendung zu reduzieren, ist von verschiedenen Räderherstellern versucht worden diese Teile aus zylindrischen Bandagen herzustellen. Umgesetzt worden ist dies bisher nur mit einem sehr aufwendigen 2 Stufen Orbital-Pressverfahren.In order to reduce this very high waste of material, various wheel manufacturers have tried to make these parts from cylindrical bandages. This has been implemented so far only with a very elaborate 2-stage orbital pressing process.

Hierbei wird zunächst eine zylindrische Bandage hergestellt, aus der dann durch orbitales Pressen eine Kalotte hergestellt wird. In einem zweiten orbitalen Pressschritt wird der Schüsselboden (Nabenflansch) vorgebildet. Anschließend erfolgt in herkömmlicher Weise die Fertigstellung der Schüssel.In this case, first a cylindrical bandage is produced, from which a calotte is then produced by orbital pressing. In a second orbital pressing step, the bowl bottom (hub flange) is preformed. Subsequently, in a conventional manner, the completion of the bowl.

Da dieses Verfahren vorwiegend auf Materialstauchen basiert, sind hierfür sehr hohe Kräfte erforderlich, so dass dies nur mit einem sehr hohen Investitionsaufwand realisiert werden kann.Since this method is based primarily on material diving, very high forces are required for this, so that this can only be realized with a very high capital outlay.

Ein anderes Verfahren ist das Auswalzen und Verschweißen eines vollen Kreisringes.Another method is the rolling and welding of a full circular ring.

Dieses Konzept ist aus den DE-PS 493 472 und US 1 399 951 bekannt.This concept is from the DE-PS 493 472 and US 1 399 951 known.

Beim Verfahren nach der DE-PS 493 472 wird ausgehend von einem Flacheisen, also einem rechteckigem Streifen, durch Walzen zwischen Kegelwalzen der Streifen nach einer Kante hin verjüngt und gleichzeitig gerundet. Hierdurch entsteht ein offener flacher Kreisring, dessen Enden dann miteinander verschweißt werden. Das Fertigformen der Schüssel erfolgt dann in einem Press- oder Ziehverfahren.In the method of the DE-PS 493 472 is tapered starting from a flat iron, so a rectangular strip, by rolling between tapered rollers of the strip to an edge and rounded at the same time. This creates an open flatter Annular ring whose ends are then welded together. The final shaping of the bowl is then done in a pressing or drawing process.

Beim Verfahren nach der US-PS 1 399 951 wird ein rechteckiger Streifen durch Walzen zwischen zylindrischen Walzen erzeugt, wobei die Walzen so zueinander angestellt werden, dass das Blech an einer Seite um so vieles mehr ausgewalzt wird, dass durch das Längen und Biegen ein offener, flacher Kreisring mit einem konischen Querschnitt entsteht. Die Enden des flachen Kreisrings stoßen auf einander. Wird ein etwas kürzerer Streifen eingesetzt entsteht zwischen den Enden des Kreisringes ein Spalt. Durch das Zusammenführen und Schweißen der Enden entsteht eine schalenförmige Form. Bei diesem Verfahren kann die Nabenflanschseite wie auch die Schüsselrandseite im gleichen Walzvorgang hergestellt werden. Vor dem Schweißen entspricht der hergestellte Querschnitt der Fertigkontur der Schüssel. Nach dem Schweißen wird ein Richten oder leichtes Umformen (konkave oder konvexe Form) in einem Presswerkzeug vorgeschlagen.In the method of the U.S. Patent No. 1,339,951 a rectangular strip is produced by rolling between cylindrical rollers, whereby the rollers are adjusted to one another in such a way that the sheet is so much more rolled on one side that the length and bending result in an open, flat circular ring with a conical cross section. The ends of the flat circular ring collide with each other. If a slightly shorter strip is used, a gap is created between the ends of the annulus. The merging and welding of the ends creates a bowl-shaped form. In this method, the hub flange side as well as the bowl edge side can be produced in the same rolling process. Before welding, the cross section produced corresponds to the finished contour of the bowl. After welding, straightening or mild forming (concave or convex shape) is proposed in a press tool.

Bei beiden Verfahren erfolgt die Materialumformung vorwiegend durch Walzen.In both processes, the material conversion takes place mainly by rolling.

Der Erfindung liegt die Aufgabe zugrunde das Herstellungsverfahren zu vereinfachen.The invention has for its object to simplify the manufacturing process.

Gelöst wird diese Aufgabe erfindungsgemäß durch ein Verfahren zum Herstellen einer Radschüssel mit den Merkmalen des Patentanspruchs 1.This object is achieved according to the invention by a method for producing a wheel disc having the features of patent claim 1.

Bei der herkömmlichen Radschüsselherstellung wird die runde Platine in einer Fließdrückmaschine umgeformt. Hierbei wird der Schüsseltopf vom Boden (Nabenflansch) bis zum Rand konisch abgestreckt (verjüngt). Der Grund für das Abstrecken ist:

  • Gewichtsreduzierung des Bauteils
  • Verfestigung des Materials durch Kaltumformung
In the conventional wheel production, the round board is formed in a flow-forming machine. Here, the bowl bowl from the bottom (hub flange) to the edge is tapered (tapered). The reason for the stretching is:
  • Weight reduction of the component
  • Solidification of the material by cold forming

Bei dem erfindungsgemäßen Verfahren wird die Verjüngung bzw. die Kaltverfestigung des Materials bereits im Streifen, vor der ersten Umformung, durch Walzen erreicht. Der Streifen wird mittels konischer Walzen einseitig gelängt, so dass ein bogenförmiges Teil entsteht. Wesentlicher Unterschied zum Stand der Technik ist aber, dass kein Kreisring hergestellt wird, mit einem Umfang von nahezu 360° ,sondern ein Teilkreisring, dessen Umfang zwischen 130°-310° liegt, vorzugsweise bei 180°.In the method according to the invention the rejuvenation or strain hardening of the material is already achieved in the strip, before the first forming, by rolling. Of the Strip is tapered on one side by means of conical rollers, so that a curved part is formed. Significant difference from the prior art, however, is that no circular ring is produced, with a circumference of nearly 360 °, but a pitch circle ring whose circumference is between 130 ° -310 °, preferably at 180 °.

Anschließend wird dieser Tellkreisring durch Runden zu einem geschlossenen Ring umgeformt, wobei dadurch gleich eine konische Bandage entsteht, die anschließend geschweißt wird.
Aus der auf diese Weise hergestellten Bandage lässt sich durch einfache Pressoperationen sowohl der Schüsselboden (Nabenflansch) als auch der Schüsseltopf umformen. Die Voraussetzung für die Schüsselbodenumformung ist, dass dieser Bereich bereits vorgeformt ist, d.h. beim Walzen des Streifens zwischen den konischen Walzen erfolgt eine Materialdickenverjüngung an der äußeren Seite des Streifens je nach gewünschter Umformung zwischen 20% und 50%. In Abhängigkeit davon liegt der Umfang des Teilkreisringes zwischen 130°und 310°.Subsequently, this Tellkreisring is formed by rounding into a closed ring, thereby creating a conical bandage immediately, which is then welded.
From the bandage produced in this way can be formed by simple pressing operations, both the bottom of the bowl (hub flange) and the bowl pot. The prerequisite for the bottom of the bowl is that this area is already preformed, ie when rolling the strip between the conical rollers, a material thickness taper occurs on the outer side of the strip depending on the desired transformation between 20% and 50%. Depending on this, the circumference of the pitch ring is between 130 ° and 310 °.

Die weitere Arbeitsfolge entspricht der gegenwärtigen FertigungsmethodeThe further work sequence corresponds to the current production method

Der Effekt des neuen Verfahrens ist, verglichen mit den derzeitig praktizierten Verfahren, eine Materialersparnis von ca. 38%.The effect of the new process is a material saving of about 38% compared to the currently practiced process.

Das erfindungsgemäße Verfahren soll nachfolgend an Hand der Zeichnungen an einem konkreten Beispiel erläutert werden, wobei die Herstellung für eine LWR Schüssel der Abmessung 22,5 x 9,00 beschrieben ist.The inventive method will be explained below with reference to the drawings in a concrete example, wherein the preparation for a LWR bowl the dimension 22.5 x 9.00 is described.

Wie sich aus der Figur 1 ergibt, ist das Ausgangsprodukt ein Streifen vom Coil oder aus Breüfiachstahl der angegebenen Abmessung. Dieser wird durch Kegelwalzen konisch ausgewalzt und dabei gleichzeitig zu einem Bogen oder Teilkreisring verformt.As is clear from the FIG. 1 results, the starting product is a strip of coil or Breüfiachstahl the specified dimension. This is conically rolled out by tapered rollers and at the same time deformed into a bow or partial circle ring.

Durch das konische Auswalzen des Materials entsteht auf der äußeren Faser des Streifens (R=540) eine größere Länge als an der inneren Faser (r340), wodurch das Biegen des Streifens zu einem Bogen erleichtert wird. Vorzugsweise hat der Teilkreisring einen Umfang von 180°, auf jeden Fall aber deutlich weniger als 360° (Fig.2).The conical rolling of the material creates a greater length on the outer fiber of the strip (R = 540) than on the inner fiber (r340), thereby facilitating the bending of the strip into a sheet. Preferably, the pitch ring has a circumference of 180 °, but in any case significantly less than 360 ° ( Fig.2 ).

Durch Runden des Teilkreisringes zu einem geschlossenen Ring entsteht eine konische Bandage (Fig.3).
Die Biegerollen an der Rundemaschine müssen wegen der unterschiedlichen Umlaufgeschwindigkeiten an der inneren und äußeren Faser des bogenförmigen Streifens konisch ausgelegt sein und unter einem bestimmten Winkel zueinender stehen.By rounding the partial circular ring into a closed ring, a conical bandage is created ( Figure 3 ).
The bending rollers on the rotary machine must because of the different Circulation speeds on the inner and outer fibers of the arcuate strip be conical and zueinender stand at a certain angle.

Das Schweißen (Abbrennstumpf-, Gleichstrompress- oder andere Schweißverfahren) sowie das Entgraten und Nachrunden der Teile erfolgt ähnlich wie bei der Feigenherstellung (Fig.4).Welding (flash butt, DC press or other welding processes) as well as deburring and rounding of the parts is similar to the production of figs ( Figure 4 ).

In der konischen Bandage wird unter einer Presse der Schüsselboden (Nabenflansch) vorgepresst und der Radius zwischen dem Schüsselboden und dem Schüsseltopf dem Fertigmaß entsprechend ausgeführt (Fig.5).In the conical bandage, the bottom of the bowl (hub flange) is pre-pressed under a press and the radius between the bottom of the bowl and the bowl of the bowl is carried out in accordance with the finished size ( Figure 5 ).

Das Umlegen des Schüsselbodens kann unter einer Presse oder auf einer Fließdrückmaschine erfolgen.The folding of the bowl bottom can be done under a press or on a flow-forming machine.

Das Umlegen unter einer Presse ist ohne größere Probleme durchführbar, da durch das Fertigen der Teile aus einer konischen Bandage der Schüsselboden (Nabenflansch) bereits zu ca. 30% - 60% vorgeformt ist.The folding under a press is feasible without major problems, since by making the parts of a conical bandage of the bowl bottom (hub flange) is already preformed to about 30% - 60%.

Das Fertigpressen des Nabenflansches kann in der konischen Bandage auch in einer Pressoperation direkt erfolgen.The final pressing of the hub flange can be done directly in the conical bandage in a pressing operation.

Das Fertigstellen des Schüsselbodens (Nabenflansch) auf einer Fließdrückmaschine würde den zusätzlichen Effekt des Kaltverfestigens in diesem Bereich mit sich bringen welches zu einer Lebensdauerverbesserung des Rades führt.The completion of the bowl bottom (hub flange) on a flow-forming machine would entail the additional effect of strain hardening in this area, which leads to an improvement in the service life of the wheel.

Eine Reduzierung der Wandstärke des Einsatzmaterials wäre möglich und würde:

  1. a eine Gewichtserleichterung des Bauteils,
  2. b eine weitere Materialeinsparung
mit sich bringen.A reduction of the wall thickness of the feedstock would be possible and would:
  1. a weight reduction of the component,
  2. b another material saving
entail.

Das Umformen des Schüsseltopfes kann:

  • durch Fließdrücken (wie bisher) oder
  • aufgrund der bereits konisch ausgewalzten Materials im diesen Bereich, durch eine einfache Pressoperation anstelle des aufwändigen Fließdrückverfahrens erfolgen.
The forming of the bowl can:
  • by flow molding (as before) or
  • due to the already conically rolled material in this area, done by a simple pressing operation instead of the elaborate flow-molding process.

Die weiteren Arbeitsgänge für die Fertigstellung einer Radschüssel entsprechen den herkömmlichen Arbeitsgängen (Fig. 6-8).The further operations for the completion of a wheel dish correspond to the conventional operations ( Fig. 6-8 ).
