Description
Es ist also praktisch unmöglich, mit den vorbekannten Vorrichtungen
eine genaue Gradwinkligkeit mit der lhse zu erziehen. In dem Bestreben, diese Hauptmängel
zu beseitigen und die industrielle-Fabrikation von Nutrollen oder Keilriemenscheiben.

Erfindung darin, dass die durch Kalt-
Die Erfindung wird in jedem Fall unter Zuwendung auf die beigefügten, nur zur.Erläuterung gegebenen Zeichnungen gut verstanden. Es zeigen: Fig.1 eine Planansicht des Rohstückes mit seiner angebrachten Unterlegplatte, Fig.2 eine Schnittdarstellung nach der Linie 2 - 2 der Fig.1, Fig.3 eine Vorderansicht der Nabe vor der Montage, Fig.4 eine Draufsicht auf die Nabe, Fig.5 und 6 Darstellungen im Schnitt vor bzw. nach dem Einfügen der Nabe, Fg.7 einen schematischen Schnitt der hydraulischem gesteuerten Kaltverformungspresse mit den Elementen, die sich auf die vorliegende Erfindung beziehen. Das Rohstück 1dessen Ausmasse derart berechnet sind, um eine Fläche zu ergeben, die dem fertiggestellten Stück gleich ist, ist an seinem Grund mit einer Zentriermulde 2 versehen. In dieser Zentriermulde 2 ist durch Funktschweissung eine runde Unterlegsche.be-3 fest angebracht. Das. Ganze ist in der Art gestanzt, um im Material der Fläche des Rohstückes und auch der Unterlegscheibe 3 Ausnehmungen 4- auszuschneiden, wie sie in Fig.1 und 2 deutlich: zu- sehen sind.The invention is in each case with reference to the attached, Only the drawings given for explanation are well understood. They show: FIG. 1 a Plan view of the blank with its attached base plate, FIG. 2 a sectional view according to the line 2 - 2 of Figure 1, Figure 3 is a front view of the hub before assembly, Fig. 4 is a plan view of the hub, Fig. 5 and 6 representations in section in front of and after inserting the hub, Figure 7 shows a schematic section of the hydraulic controlled Cold forging press with the elements that relate to the present invention relate. The blank 1, the dimensions of which are calculated in such a way as to form an area which is equal to the finished piece is at its bottom with a Centering recess 2 provided. In this centering 2 is a radio welding round washer.be-3 firmly attached. That. Whole is punched in order 3 recesses in the material of the surface of the blank and also of the washer 4- Cut out as they can be seen clearly in Fig. 1 and 2.
Die Nabe -5, insbesin Fig.3 und 4 gezeigt, ist durch Kalt-
Nachdem das Rohstück so mit einem Zapfen ausgerüstet ist und mit Wasser
oder einer anderen Flüssigkeit gefüllt ist, wird es in eine sich -öffnende Form
17 gestellt. Diese Form 17 wird durch eine Zwinge 18 geschlossen gehalten, wobei
die Zwinge 18 von einem in der Vertikalen beweglichen Tisch 19 gehalten wird. Der
sich öffnende Teil 17 wird mit seinem unteren Element 22 durch einen Stössel 21
betrieben. Die untere Fläche des genannten Elementes 2o ist leicht konvex und dieses
Element ist an den Stössel 21 durch eine bewegliche Verbindung 22 angebracht. a
Was das obere Element 23 der Form betrifft, so trägt es eine Bohrung 24, die in
der Achse eines Zylinders 25 angeordnet ist. Inder Bohrung.24 liegt ein Tauchkolben
26. Im Moment der Inbetriebnahme der Fresse steigt der Stössel 21 und zieht das
untere Element 2o mit sich. Damit wird das Rohstück mitgenommen in des Art, dass
die Knickung des Rohstückes 1 beginnt, sich zu vollziehen,und zwar zu gleicher Zeit.
Nach einer kurzen Strecke dringt der Zapfen 12 der Nabe in die Bohrung 24 des oberen
Elementes ein, das fest verankert und genau zentriert ist. Die Zentrierung des hergestellten
Stückes ist somit zwangsläufig, ohne dass ein Einklemmen notwendig ist oder dass
durch einen evtl. Ausrichtungsfehler die Zentrierung beeinträchtigt werden könnte.
Dies erfolgt in der Hauptsache wegen der konvexen
