Description
Die Erfindung betrifft ein Verfahren zum formschlüssigen Verbinden eines topfförmigen Formkörpers im Bereich seiner Wandung mit einem ringförmigen, über den Formkörper gestülpten Außenkörpers, insbesondere eines Bremsscheibenkörpers, durch Innenhochdruckumformen.The The invention relates to a method for the positive connection of a cup-shaped molding in Area of its wall with an annular, slipped over the shaped body outer body, in particular a brake disk body, through Hydroforming.
Bei
einem bekannten Verfahren dieser Art (
Die
Technik des Innenhochdruckumformens ist für verschiedene Anwendungszwecke
bekannt. Bei einem bekannten Anwendungszweck (
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum formschlüssigen Verbinden eines topfförmigen Hohlkörpers mit einem ringförmigen Außenkörper zu schaffen, wobei eine große radiale Umformung des Formkörpers möglich sein soll.Of the Invention is based on the object, a method for positive connection a pot-shaped hollow body with an annular Outer body too create a big one radial deformation of the molding possible should be.
Diese Aufgabe wird erfindungsgemäß beim eingangs genannten Verfahren dadurch gelöst, dass die Wandung des Formkörpers bei innen- und außenseitiger radialer Abstützung von der Innenseite aus mit Hochdruck beaufschlagt und gleichzeitig axial gestaucht wird, so dass die Wandung nach außen lokal um eine radiale Profilierung am Innenrand des Außenkörpers herum verformt wird.These The object is achieved according to the invention at the beginning solved by said method, that the wall of the molding inside and outside radial support pressurized from the inside and simultaneously is compressed axially, so that the wall to the outside locally is deformed around a radial profiling on the inner edge of the outer body around.
Bei einem solchen Verfahren lassen sich lokal hohe Umformgrade erzielen, weil durch die die Innenhochdruckumformung begleitende Stauchung der Materialfluß zu den zu verformenden Bereichen gefördert wird. Deshalb kommt man mit vergleichsweise kleinen Hochdrücken aus. Die dabei benötigte Stauchkraft läßt sich vor allem dann problemlos einleiten, wenn sie auf den freien Rand der Wandung ausgeübt wird. Deshalb lässt sich mit dem erfindungsgemäßen Verfahren auch eine auf Dauer gute formschlüssige Verbindung zwischen dem topfförmigen Formkörper und dem ringförmigen Außenkörper erzielen.at such a process can be achieved locally high degrees of deformation, because by the internal hydroforming accompanying compression of the Material flow too the areas to be deformed. That's why you come with comparatively small high pressures. The required compression force let yourself especially then easily initiate when on the free edge exercised the wall becomes. Therefore lets with the inventive method also a permanent good positive connection between the cup-shaped moldings and the annular one Achieve outer body.
Eine gute formschlüssige Verbindung ist vor allem für die Verbindung zwischen einem Bremsscheibenkörper und dem topfförmigen Formkörper von Vorteil. Für diesen Anwendungsfall ist nach einer Ausgestaltung der Erfindung vorgesehen, dass in den ringscheibenförmigen Bremsscheibenkörper, dessen Profilierung am Innenrand als radiale Nasen ausgebildet sind, der als Tragkörper dienende Formkörper mit noch glatter Wandung eingesetzt wird, um dann durch die Innenhochdruckbeaufschlagung der Wandung im Bereich einer jeden Nase Taschen um die Nasen herum geformt zu werden. So läßt sich ein optimaler Formschluß ohne Spiel verwirklichen. Bei einer solchen Bremsscheibe kann sich der beim Bremsen durch die Bremswärme unmittelbar erwärmte Bremsscheibenkörper radial frei ausdehnen, ohne daran durch den zentralen Tragkörper gehindert zu werden. Die formschlüssige Verbindung aus miteinander im Eingriff stehenden Nasen und Taschen lassen nämlich diese freie radiale Ausdehnung bei Aufrechterhaltung des für die Aufnahme des Bremsmomentes benötigten Formschlusses in Umfangsrichtung zu. Für die zweiteilige Bremsscheibe können die für die jeweilige Beanspruchung und Herstellung und das Schwingungsverhalten (Quietschgeräusche) am besten geeigneten Materialien ausgewählt werden. Das sind zum Beispiel für den Bremsscheibenkörper Gußmaterial, aber auch Keramikwerkstoffe, und für den Tragkörper durch bewährte Verfahren umformbares Flachmaterial, insbesondere Blech vor allem aus Stahl, aber auch Verbundwerkstoffe.A good form-locking Connection is mainly for the connection between a brake disc body and the cup-shaped molding of Advantage. For This application is according to an embodiment of the invention provided that in the annular disk-shaped brake disk body whose Profiling on the inner edge are formed as radial lugs, the as a supporting body serving moldings is used with even more smooth wall, then by the internal high pressure application the wall in the area of each nose pockets around the noses to be molded. That's how it works an optimal form fit without Realize play. In such a brake disc, the when braking by the brake heat immediately heated brake disk body expand radially freely, without being hindered by the central support body to become. The form-fitting Connection of meshing noses and pockets namely let This free radial expansion while maintaining the for recording the braking torque needed Positive connection in the circumferential direction too. For the two-piece brake disc, the for the respective stress and production and the vibration behavior (Squeaking) the most suitable materials are selected. For example for the brake disc body casting material, but also ceramic materials, and for the support body by proven methods deformable flat material, in particular sheet metal, mainly of steel, but also composites.
Vorzugsweise werden beim Innenhochdruckumformen die um jede Tasche herum liegenden Bereiche der Wandung durch eingesetzte Distanzelemente auf einem einstellbaren radialen Abstand zum Innenrand des Bremsscheibenkörpers gehalten. Dadurch wird erreicht, daß in jedem Betriebszustand der Bremsscheibe die einzige Verbindung zwischen Tragkörper und Bremsscheibenkörper die Nasen und Taschen sind und Freiraum für eine eventuell vorgesehene Innenbelüftung des Bremsscheibenkörpers verbleibt.Preferably In hydroforming, the areas around each pocket are used the wall by inserted spacers on an adjustable held radial distance to the inner edge of the brake disc body. Thereby is achieved that in each operating state of the brake disc, the only connection between the support body and brake disk body the noses and pockets are and free space for any intended internal ventilation the brake disc body remains.
