Die iirfindung betrifft ein ^erfahren zur Herstellung von Achsgehäusen für Kraftfahrzeugachsen mittels Explosivumformung im Gesenk,The invention relates to an experience in production of axle housings for motor vehicle axles by means of explosive forming in the die,
JSs sind bereits Verfahren zur Herstellung von Achsgehäusen bekannt und vorgeschlagen, nach denen Achsgehäuse für angetriebene J'ahrzeugachsen als Blechhalbschalen auf Pressen umgeformt und soweit vorgefertigt sind, daß sie nach dem Zusammenschweißen das fertige Achsgehäuse ergeben. Weiterhin bekannt und vorgeschlagen ist ein ^erfahren, nach welchem mittels Explosivumformung im Gesenk aus geschlitzten Rohrprofilen das Achsgehäuse gefor&t wird.JSs processes for the production of axle housings are already known and proposed, according to which axle housings for driven vehicle axles as sheet metal half-shells reshaped on presses and prefabricated to the extent that they are finished after being welded together Axle housing result. Also known and proposed is a ^ experience, according to which by means of explosive forming The axle housing is formed in the die from slotted tubular profiles.
Die bekannten und vorgeschlagenen Verfahren zur Herstellung von Achsgehäusen haben die Nachteile eines hohen Investitionsaufvandes, eines hohen Bedarfs an Energie für Maschinen und Erwlrmungseinrichtungen und ungünstiger Arbeitsverhältnisse. Sin weiterer Nachteil sind die bei dieeen Verfahren auftretenden Formungenauigkeiten.The known and proposed methods for producing axle housings have the disadvantages of a high Investment costs, a high demand for energy for machines and heating systems and less favorable Working conditions. Another disadvantage is the inaccuracies in shape that occur in these processes.

Bei der Explosivumformung von geschlitzten Rohren im Gesenk ermöglichen die Schlitze oder Sollreißstellen das Ausbiegen des Rohres. Nachteilig ist bei den angebrachten Schlitzen die ungünstige Sinbringungsmöglichkeit der Sprengladung und deren genaue Positionierung. Die sich im ümformbereich nach dem Umformen ergebende Innenform erfordert eine aufwendige Nachbearbeitung. Über die genau abgestimmte^ sichere zentrische Anordnung der Sprengladung ist in der Praxis bisher keine günstige Lösung bekannt, die sich bei einer ßeriAnfertigung ökonomisch anwenden ließe.In the explosive forming of slotted tubes in the die, the slots or predetermined tear points enable bending the pipe. The disadvantage of the slots provided is the unfavorable possibility of bringing them into place the explosive charge and its exact positioning. Which are in the forming area after forming The resulting inner shape requires extensive post-processing. Via the precisely coordinated ^ safe centric Arrangement of the explosive charge is in practice so far no favorable solution known, which is in a ßeri production could be used economically.

Zweck der Erfindung ist die Beseitigung der aufgeführten Mangel und Nachteile,The purpose of the invention is to eliminate those listed Shortcomings and disadvantages,
Aufgabe der Erfindung ist die Entwicklung eines Verfahrens, mit welchem eine ökonomisch und technisch günstige !fertigung von Achsgehäusen für Kraftfahrzeugachsen unter Anwendung der Explosivumformung im Gesenk in großen Stückzahlen betrieben werden kenn.The object of the invention is to develop a method with which an economical and technical cheap! production of axle housings for motor vehicle axles using explosive forming in the die be operated in large numbers.
Die Aufgabe wird erfindungsgemäß durch nachfolgende Verfahrensschritte gelöst.According to the invention, the object is achieved by the following method steps.
Zwei Profilhälften werden in einem vorbestimmten Bareich mit spezifisch gestalteten Pormausschnitten für die spätere Aufnahem d;s Achsantriebes versehen. Der Umriß und die Lage der Pormausschnitte muß entsprechend der Abmessungen und der Lage des Achsantrieb*s jeweils konstruktiv festgelegt werden.Two profile halves are in a predetermined range with specifically designed cutouts for the Later recording of the axle drive provided. The outline and the position of the cutouts must correspond to the Dimensions and the position of the final drive * are each constructive be determined.
Nach dem Einbringen der Pormausschnitte werden die beiden Profile, vorzugsweise darch ein Hochleistungsschweißverfahren so zusammengefügt, daß ein Hohlprofil entsteht. Dieses beidseitig mit Formaasschnitten versehene Hohlprofil wird nach Einlegen in ein Gesenkunterteil in Bezug auf den l'ormausschnitt positioniert. Nahcdem die offenen Enden des Hohlprofils verschlossen worden sind, wird dieses mit einem geeigneten bildsamen Druckübertrag ungsmedium voll gefüllt, wozu vorzugsweise feuchter Sand verwendet wird.After the cutouts have been made, the two Profiles, preferably darch a high-performance welding process joined together in such a way that a hollow profile is created. This hollow profile, which is provided with shaped cuts on both sides, is inserted into a lower die part in Positioned in relation to the l'orm cutout. Near the open ends of the hollow profile have been closed, this is done with a suitable plastic pressure transfer ungsmedium completely filled, for which moist sand is preferably used.
Die Füllung wird so durchgeführt, daß gleichzeitig im Bereich der Formauεschnitte der erforderliche Hohlraum für die Sprengladung entsteht und die Ladung durch das sie umgebende Druckübertragungsmedium später in ihrer Lage bestimmt wird. Nach Einbringen der dosierten Sprengladung mit Zünder sowie Schließen und Verriegeln des Gesenkes und strnseitiges Verdammen des Hohlprofils wird der Sprengstoff gezündet.The filling is carried out so that at the same time in Area of the form cutouts the required cavity for the explosive charge and the charge through the surrounding pressure transfer medium later in their location is determined. After introducing the dosed explosive charge with detonator as well as closing and locking of the die and damaging the hollow profile on the strand side the explosives are detonated.
Durch die aufgeprägte kinetische Energie des Druckübertragungsmediums erfolgt das Ausbiegen des HohlprofilsDue to the applied kinetic energy of the pressure transmission medium the hollow profile is bent out
