Abstract
Die Erfindung bezieht sich auf ein Verfahren zum Innenhochdruckumformen eines topfförmigen Formkörpers (2) im Bereich seiner Wandung (4), insbesondere zur formschlüssigen Verbindung eines ringförmigen Bremsscheibenkörpers (1) mit dem Formkörper (2) zu einer Scheibenbremse. Bei diesem Verfahren wird die Wandung (4) bei innen- und außenseitiger radialer Abstützung von der Innenseite aus mit Hochdruck beaufschlagt und gleichzeitig axial gestaucht, so daß die Wandung (4) nach außen verformt wird. Im Falle der Herstellung einer Radscheibe weist der Bremsscheibenkörper (1) an seinem Innenrad radiale Nasen auf, um die bei der Innenhochdruckbeaufschlagung der Wandung Taschen (5) herumgeformt werden.The invention relates to a method for the internal high pressure forming of a cup - shaped molded body (2) in the region of its wall (4), in particular for the positive connection of an annular brake disc body (1) to the molded body (2) to form a disc brake. In this method, the wall (4) is subjected to high pressure from the inside with radial support on the inside and outside and at the same time is axially compressed, so that the wall (4) is deformed outwards. In the case of the manufacture of a wheel disc, the brake disc body (1) has radial lugs on its inner wheel, around which pockets (5) are formed when the wall is subjected to high internal pressure.
Description
Die Erfindung betrifft ein Verfahren zum Umformen eines topfförmigen Formkörpers im Bereich seiner Wandung, insbesondere zur formschlüssigen Verbindung eines ringförmigen Bremsscheibenkörpers mit dem als Tragkörper dienenden Formkörper.The invention relates to a method for forming a cup-shaped molding in the area of its wall, in particular for a positive connection an annular brake disk body with that as a supporting body serving molded body.
Bei einem bekannten Verfahren dieser
Art (
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Umformen eines topfförmigen Formkörpers zu schaffen, das eine große radiale Umformung ermöglicht.The invention is based on the object Process for reshaping a cup-shaped shaped body create that a big one allows radial deformation.
Diese Aufgabe wird erfindungsgemäß beim eingangs genannten Verfahren dadurch gelöst, daß die Wandung bei innen- und außenseitiger radialer Abstützung von der Innenseite aus mit Hochdruck beaufschlagt und gleichzeitig axial gestaucht wird, so daß die Wandung lokal nach außen verformt wird.This object is achieved at the outset mentioned method solved that the Wall on the inside and outside radial support Pressurized from the inside and at the same time is axially compressed so that the Wall locally to the outside is deformed.
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.Let go with such a procedure locally high degrees of forming are achieved because of the high pressure forming accompanying compression of the material flow to the areas to be deformed is promoted. That's why you can get by with comparatively small pressures. The compressive force required let yourself Above all, initiate easily when it is on the free edge the wall exercised becomes.
Wegen der mit dem erfindungsgemäßen Verfahren problemlos zu erzielenden hohen Verformungsgrade eignet sich das Verfahren insbesondere für eine auf Dauer gute formschlüssige Verbindung zwischen dem ringförmigen Bremsscheibenkörper und dem topfförmigen Formkörper. Für diesen Anwendungsfall sollte nach einer Ausgestaltung dafür in den ringscheibigen Bremsscheibenkörper, der an seinem Innenrand mit radialen Nasen versehen ist, der als Tragkörper dienende Formkörper mit noch glatter Wandung eingesetzt werden, 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.Because of the method according to the invention This is suitable for high degrees of deformation that can be easily achieved Procedure especially for a good form-fitting in the long run Connection between the ring-shaped Brake disc body and the pot-shaped Moldings. For this Use case should be in the ring-shaped brake disc body, which is provided with radial lugs on its inner edge, which as supporting body serving molded body can be used with a smooth wall and then through the internal high pressure the wall in the area of each nose pockets around the nose to be shaped. So you can an optimal form fit without Realize game. With such a brake disc, the when braking due to the braking heat immediately warmed brake disk body expand radially freely without being hindered by the central support body to become. The form-fitting Connection of interlocking lugs and pockets let namely this free radial expansion while maintaining that for inclusion of the braking torque required Form fit in the circumferential direction. For the two-part brake disc can the for the respective stress and manufacture and the vibration behavior (Squeaking) most suitable materials are selected. For example for the Brake disc body cast material, but also ceramic materials, and for the supporting body through proven processes formable flat material, in particular sheet metal, especially made of steel, but also composite materials.
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.Are preferably used in hydroforming the areas of the wall around each pocket by inserted Spacer elements at an adjustable radial distance from the inner edge the brake disc body held. It is thereby achieved that the Brake disc the only connection between the support body and brake disk body the noses and pockets are and free space for a possibly provided internal ventilation of the brake disc body remains.
