Abstract

A continuous source material (3) is formed into rings (5) and cut to size. The ring ends (6,7) are butt welded, and the rings are finished by plastic forming at room temperature. The side walls (9,10) are parallel to each other. Rings are formed and cut by a roller and cutter machine, and the rings are cut individually. The source material is pre-formed and has an approx. oval cross section.

Description

Technisches GebietTechnical field

Die Erfindung betrifft ein Verfahren zur Herstellung von Blechringen, die zumindest zwei einander gegenüberliegende Seitenflächen haben.The invention relates to a method for producing sheet metal rings, at least have two opposite side faces.

Stand der TechnikState of the art

Es ist bekannt Blechringe aus Blechvorlagen durch Ausstanzen herzustellen. Bei diesem Verfahren fallen erhebliche Mengen an Abfall an. Darüber hinaus sind die Seitenflächen der Blechringe häufig nicht völlig parallel und mit vom Stanzen herrührenden Graten versehen. Für viele Anwendungszwecke reichen derartige Blechringe durchaus aus. Häufig werden aber auch Blechringe gewünscht, deren Seitenflächen sich parallel zueinander erstrecken sollen und die an ihren Innen- beziehungsweise Außenkanten keine Grate haben.It is known to produce sheet metal rings from sheet templates by punching them out. This process generates significant amounts of waste. Furthermore the side surfaces of the sheet metal rings are often not completely parallel and with the Stamping burrs originating. Sufficient for many applications such sheet metal rings from. However, sheet metal rings are often also desired, whose side surfaces should extend parallel to each other and the have no burrs on their inner and outer edges.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung von Blechringen zu schaffen, bei dem möglichst ein geringer beziehungsweise gar kein Abfall anfällt bei dem darüber hinaus die Seitenflächen des Blechrings parallel zueinander verlaufen sowie die Gratbildung an den Ringrändern vermieden wird. Die Blechringe sollen eine hohe Formgenauigkeit und Festigkeit aufweisen.The invention has for its object a method for producing To create sheet metal rings with the least possible or even there is no waste in the case of the side surfaces of the sheet metal ring run parallel to each other and avoid burrs on the ring edges becomes. The sheet metal rings are said to have high dimensional accuracy and strength exhibit.

Die Lösung der gestellten Aufgabe erfolgt bei einem Verfahren der eingangs genannten Art erfindungsgemäß dadurch, daß ein endloses Ausgangsmaterial zu Ringen geformt und abgelängt wird, und daß die Ringe im Bereich ihrer Enden stumpf verschweißt und nachfolgend durch plastische Verformung in die Gestalt von Blechringen überführt werden. Nach dem neuen Verfahren wird somit ein rundes Material zu Ringen geformt, deren Enden stumpf miteinander verschweißt werden. Diese Ringe werden dann einer Prägevorrichtung zugeführt und zu Blechringen geprägt. Die Seiten eines solchen Blechrings sind einwandfrei parallel zueinander und eine Gratbildung tritt nicht auf. Abfälle werden vollständig vermieden.The task is solved with a method of the beginning mentioned type according to the invention in that an endless starting material is formed into rings and cut to length, and that the rings in the area of their ends butt welded and then plastically deformed into the Shape of sheet metal rings are transferred. According to the new procedure thus a round material formed into rings, the ends of which are butted together be welded. These rings are then fed to an embossing device and shaped into sheet metal rings. The sides of such a sheet metal ring are perfectly parallel to each other and no burrs occur. Waste completely avoided.

Der so hergestellte Blechring hat noch den Vorteil, daß er eine hohe Festigkeit hat, da die Kraftlinien aus dem Ausgangsmaterial erhalten bleiben und sich im Blechring wiederfinden.The sheet metal ring produced in this way has the advantage that it has a high strength has because the lines of force from the raw material are preserved and in the Find the metal ring again.

Es ist günstig wenn für das Ausgangsmaterial ein Drahtcoil verwendet wird, von dem das Material abgezogen, aufgewickelt und abgelängt wird. Für die Bildung der Ringe und ihre Ablängung wird eine Roll- und Schneideinrichtung verwendet. Dabei ist es günstig, wenn die Ringe einzeln abgelängt werden.It is advantageous if a wire coil is used for the starting material where the material is drawn off, wound up and cut to length. For education a rolling and cutting device is used for the rings and their cutting to length. It is advantageous if the rings are cut to length individually.

Das Ausgangsmaterial kann gegebenenfalls vorgeformt sein und einen etwa ovalen Querschnitt haben. Dieses kann bereits bei der Herstellung des Ausgangsmaterials geschehen oder auch dann, wenn das Ausgangsmaterial vom Coil abgezogen wird.The starting material can optionally be preformed and approximately one have an oval cross-section. This can already be done during the production of the starting material happen or even if the starting material from Coil is withdrawn.

Aus Festigkeitsgründen ist es günstig wenn die nachfolgende plastische Verformung bei Raumtemperatur vorgenommen wird. Bei einer Reihe von Einsatzzwecken ist es gündstig, wenn die Seitenflächen der Blechringe sich parallel zueinander erstrecken. Die Blechringe können jedoch auch mit unterschiedlichen Querschnittsprofilen ausgestattet werden um in axialer und radialer Richtung mit geringstem Materialaufwand höchsten Belastungen stadhalten zu können. Dieses hat besondere Bedeutung dann, wenn die Ringe als Blechstützkörper mit einer Ummantelung aus polymerem Werkstoff versehen als Radialdichtungen zum Einsatz kommen.For reasons of strength, it is advantageous if the subsequent plastic deformation is carried out at room temperature. For a number of uses it is expedient if the side surfaces of the sheet metal rings are parallel extend to each other. The sheet metal rings can also be used with different Cross-sectional profiles are fitted around in the axial and radial directions to be able to withstand the highest loads with the least amount of material. This is particularly important when the rings are used as sheet metal support bodies provided with a jacket made of polymer material as radial seals are used.

Ausführung der ErfindungImplementation of the invention

In der Figur sind die einzelnen Verfahrensschritte für die Herstellung des Blechrings 1 dargestellt. Von dem Drahtcoil 2 wird der Profildraht 3 abgezogen und auf einen Wickel 4 mit vorgegebenem Durchmesser aufgewickelt und dabei gleichzeitig abgelängt. Der Wickel 4 ist eine Roll- und Schneideinrichtung, in der die Ringe 5 einzeln abgelängt werden. Das Ausgangsmaterial 3 wird auf diese Weise zu einem noch offenen Ring 5 geformt. Der so gebildete Ring 5 wird im Bereich seiner Enden 6, 7 stumpf verschweißt. Hierfür wird der Ring 5 in eine Schweißeinrichtung eingelegt und seine Enden 6, 7 aneinandergefügt. Nach dem Stumpfverschweißen wird der Ring 5 in eine Prägeeinrichtung 8 eingeführt und dort plastisch verformt. Der fertige Blechring 1 hat die in der Figur gezeigte Form mit den sich parallel zueinander erstreckenden Oberflächen 9, 10. Das gesamte Verfahren wird bei Raumtemperatur vorgenommen und ist abfallfrei.The figure shows the individual process steps for the production of the Sheet metal ring 1 shown. The profile wire 3 is withdrawn from the wire coil 2 and wound on a roll 4 with a given diameter and thereby cut to length at the same time. The winding 4 is a rolling and cutting device, in the rings 5 are cut to length. The starting material 3 is on shaped in this way to a still open ring 5. The ring 5 thus formed is butt welded in the area of its ends 6, 7. Ring 5 placed in a welding device and its ends 6, 7 joined together. After butt welding, the ring 5 is inserted into an embossing device 8 and plastically deformed there. The finished sheet metal ring 1 has that in the figure shape shown with the surfaces 9 extending parallel to one another, 10. The entire procedure is done at room temperature and is waste free.
