Abstract
Ein Verfahren zum Umformen einer Blechronde (1) mit einem zentrischen Loch (2), die auf einem um eine Achse (3) rotierenden Werkzeug (4) aufliegt und eine Dicke a1 sowie einen Durchmesser d1 aufweist, der kleiner als der Durchmesser des Werkzeugs (4) ist, zeichnet sich dadurch aus, dass eine oder mehrere Drückrolle(n) vorzugsweise axial in das Material der Blechronde eingetaucht und radial nach außen bewegt wird/werden, so dass die Fläche der Blechronde (1) radial in allen Richtungen vergrößert wird, so dass aus der Blechronde mit dem Ausgangsdurchmesser d1 und der Dicke a1 ein vorzugsweise rotationssymmetrisches Teil, insbesondere eine weitere Blechronde mit einem größeren Durchmesser d2 und einer zumindest abschnittsweise oder durchgehend verringerten Dicke a2 geformt wird.A method for forming a sheet metal blank (1) having a centric hole (2) resting on a tool (4) rotating about an axis (3) and having a thickness a1 and a diameter d1 smaller than the diameter of the tool ( 4), characterized in that one or more spinning roller (s) is preferably immersed axially in the material of the sheet metal blank and is moved radially outwards, so that the surface of the sheet metal blank (1) is radially enlarged in all directions, so that a preferably rotationally symmetrical part, in particular a further sheet metal blank having a larger diameter d2 and an at least partially or continuously reduced thickness a2, is formed from the sheet metal blank with the starting diameter d1 and the thickness a1.
Description
Die Erfindung betrifft ein Verfahren zum Umformen einer Blechronde mit einem zentrischen Loch, die auf einem um eine Achse rotierenden Werkzeug aufliegt und eine Dicke a1 sowie einen Durchmesser d1 aufweist, der kleiner als der Durchmesser des Werkzeugs ist.The The invention relates to a method for forming a sheet metal blank with a centric hole on a tool rotating about an axis rests and has a thickness a1 and a diameter d1, which is smaller than the diameter of the tool.
Die Erfindung hat die Aufgabe, neue Wege bei der Umformung von Blechronden mittels Drückrollen zu gehen.The Invention has the task of finding new ways in the transformation of circular blanks by means of spinning rollers to go.
Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruchs 1.The Invention solves this object by the subject matter of claim 1.
Dabei werden eine oder mehrere Drückrolle(n) vorzugsweise zunächst axial in das Material der Blechronde eingetaucht und dann radial nach außen bewegt (dies ist so zu verstehen, dass der Weg Drückrolle zumindest eine Bewegungskomponente in radialer Richtung enthält), wodurch die Fläche der Blechronde radial in allen Richtungen vergrößert wird, so dass aus der Blechronde mit dem Ausgangsdurchmesser d1 und der Dicke a1 ein rotationssymmetrisches Teil, insbesondere eine Blechronde mit einem größeren Durchmesser d2 und einer zumindest abschnittsweise oder durchgehend verringerten Dicke a2 hergestellt wird.there be one or more spinning roller (s) preferably first axially immersed in the material of the sheet metal blank and then radially moved outward (This is to be understood as meaning that the path is at least one component of movement in a spinning roller contains radial direction), causing the area the sheet metal blank is enlarged radially in all directions, so that from the Blechronde with the output diameter d1 and the thickness a1 a rotationally symmetric Part, in particular a sheet metal blank with a larger diameter d2 and a at least partially or continuously reduced thickness a2 will be produced.
Vorteilhafte Ausgestaltungen sind den Unteransprüchen zu entnehmen.advantageous Embodiments are to be taken from the subclaims.
Mit der Erfindung ist es möglich, aus einer Blechronde mit einem Ausgangsdurchmesser d1 und einer Dicke a1 eine Blechronde oder direkt ein rotationssymmetrisches Teil, insbesondere ein Getriebeteil, mit einem größeren Durchmesser d2 und einer zumindest abschnittsweise oder durchgehend verringerten Dicke a2 herzustellen. Es ist sogar möglich, den Durchmesser um mehr als 10% insbesondere mehr als 20% zu vergrößern.With the invention it is possible from a circular sheet metal with an initial diameter d1 and a Thickness a1 a sheet metal blank or directly a rotationally symmetric part, in particular a transmission part, with a larger diameter d2 and at least one to produce section-wise or continuously reduced thickness a2. It is even possible that Diameter increase by more than 10%, in particular more than 20%.
Der Begriff der Blechronde ist in Hinsicht auf das durch das Umformen hergestellte Teil nicht zu eng zu sehen. Es ist einerseits möglich, eine ebene Blechronde herzustellen. Diese kann aber auch konturiert sein, wenn das Werkzeug entsprechend konturiert ist. Zudem kann die Blechronde direkt zu einem Getriebeteil oder dgl. bearbeitet oder weiterverarbeitet werden.Of the Term of the sheet metal blank is in regard to that by the reshaping made part not too tight. It is possible on the one hand, one produce flat sheet metal blank. This can also be contoured, if the tool is contoured accordingly. In addition, the sheet metal can directly to a gear part or the like. Edited or further processed become.
Das Verfahren kann in verschiedensten Bereichen eingesetzt werden. Eine bevorzugte Anwendung ist das Vergrößern „kleiner" Blechronden, wie sie z.B. bei der Radschüsselherstellung für LKW quasi als Verschnitt anfallen, der ansonsten verschrottet werden müsste. Mit der Erfindung ist dagegen eine Nutzung für einen anderen Zweck, z.B. zur Herstellung von Radschüsseln für kleinere Nutzfahrzeuge noch möglich. Der hierdurch erreichbare Kostenvorteil ist nicht zu unterschätzen.The Method can be used in a variety of areas. A preferred application is the enlargement of "small" circular blanks, as for example in the Radschüsselherstellung for trucks almost as a waste incurred, which are otherwise scrapped would. By contrast, the invention makes use for a different purpose, e.g. for the production of wheel dishes for smaller ones Commercial vehicles still possible. The resulting cost advantage can not be underestimated.
Alternativ ist es möglich, aus einer Ronde größerer Ausgangsdicke direkt ein im wesentlichen rotationssymmetrisches Teil quasi beliebiger Art zu schaffen, dass bereichsweise eine kleinere Dicke und einen größeren Durchmesser aufweist. Mögliche Anwendungen ergeben sich auch im Bereich der Starterkränze. Bei all diesen Teilen ergeben sich durch die Erfindung neue Lösungsansätze, die z.B. den Materialabfall und damit die Herstellkosten erheblich senken.alternative Is it possible, from a blank of larger initial thickness directly a substantially rotationally symmetric part virtually arbitrary Way of creating that in places a smaller thickness and a larger diameter having. Possible applications also arise in the field of starter wreaths. With all these parts result from the invention, new approaches, the e.g. the material waste and thus significantly reduce the manufacturing costs.
Zwar ist es bekannt, dass sich eine Ronde beim Eintauchen einer Drückrolle etwas aufweitet, so beim Anformen einer Nabe. Das Aufweiten ist aber nur ein Nebeneffekt, der an einem Wiederlagerfutter zum Einspannen der Ronde führt. Zudem wird die Ronde nicht radial nach außen sondern radial nach innen bewegt, so dass kein gezieltes Aufweiten, insbesondere nicht um mehr als die den Unteransprüchen genannten Prozentangaben erfolgt.Though It is known that a Ronde immersed in a spinning roller something dilates, so when molding a hub. The widening is but only a side effect to a repository feed for clamping the Ronde leads. In addition, the Ronde is not radially outward but radially inward moves, so no targeted widening, especially not around more than the subclaims percentages given.
