Die vorliegende Erfindung beschäftigt sich mit dem Problem, für die Herstellung eines Hohlkörpers, der wenigstens eine einstückig daran ausgebildete und mit wenigstens einem Loch versehene Lasche aufweist, einen besonders preiswerten Weg aufzuzeigen, der sich in besonderer Weise für eine Massenproduktion eignet.The present invention employs dealing with the problem, for the production of a hollow body, the at least one piece formed thereon and provided with at least one hole tab has to show a particularly inexpensive way, the in a special way for a mass production is suitable.
Erfindungsgemäß wird dieses Problem durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.According to the invention this Problem with the objects the independent one claims solved. Advantageous embodiments are the subject of the dependent Claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, einen nach dem Innenhochdruck-Umformverfahren hergestellten Hohlkörper noch im Umformwerkzeug mit einem Loch zu versehen und um das Loch herum eine Lasche freizuschneiden. Der anschließend aus dem Umformwerkzeug entnehmbare Hohlkörper ist dann mit der gewünschten, das Loch enthaltenden Lasche einstückig ausgebildet. Wesentlich ist dabei, dass das Umformen, das Lochen und das Freischneiden in ein und demselben Umformwerkzeug, also ohne Werkzeugwechsel durchgeführt werden können, wodurch die Taktzeiten zur Herstellung des Hohlkörpers besonders klein gewählt werden können.The Invention is based on the general idea, one after the hydroforming process produced hollow body still to provide in the forming tool with a hole and around the hole to cut a tab around. The then from the forming tool removable hollow body is then with the desired, the tab containing the hole integrally formed. Essential is that the reshaping, the punching and the free cutting in one and the same forming tool, so be performed without tool change can, whereby the cycle times for the production of the hollow body are chosen to be particularly small can.
Bei einer zweckmäßigen Weiterbildung kann die Lasche vor dem Herausnehmen des Hohlkörpers außerdem umgebogen werden, wodurch ein weiterer Herstellungsschritt in das Umformwerkzeug integriert wird.at an appropriate training the tab can also be bent before removing the hollow body, whereby a further manufacturing step is integrated into the forming tool.
Von besonderer Bedeutung ist eine Ausführungsform, bei welcher der Lochstempel im Schneidstempel hubverstellbar gelagert ist. Bei einer derartigen Ausführungsform kann die Relativlage des Lochs bezüglich der Lasche relativ- genau vorgegeben werden und mit einer hohen Reproduzierbarkeit eingehalten werden. Des Weiteren besitzt das Umformwerkzeug dadurch einen vergleichsweise preiswerten Aufbau, da auf diese Weise der Lochstempel quasi in den Schneidstempel integriert ist.From Of particular importance is an embodiment in which the Punch in the cutting punch is mounted adjustable in stroke. At a such embodiment the relative position of the hole relative to the tab can be relatively accurate be specified and maintained with a high reproducibility become. Furthermore, the forming tool thereby has a comparatively inexpensive structure, because in this way the punch virtually in the cutting punch is integrated.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Further important features and advantages of the invention will become apparent from the Dependent claims, from the drawings and from the associated description of the figures the drawings.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It it is understood that the above and the following yet to be explained features not only in the specified combination, but also in other combinations or alone, without to leave the scope of the present invention.
