Description

Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Scheibenrädern für Feldbahnen oder ähnliche Bahnen durch Pressen. Der Erfindung gemäß soll der Block, aus welchem das Rad gepreßt wird, durch einen einzigen Vorpreßstempel unmittelbar in die untere Matrize hineingepreßt werden, worauf nach Fortnahme des Vorpreßstempels der Fertigstempel die Pressung vollendet. DiesThe invention relates to a method for the production of disc wheels for field tracks or similar tracks by pressing. According to the invention, the block from which the wheel is pressed by a single Vorpreßstempel be pressed directly into the lower die, whereupon after removal of the prepress ram the finishing ram completes the pressing. this

ίο bedeutet gegenüber den bisherigen Verfahren eine wesentliche Vereinfachung und damit eine erhebliche Verbilligung des Werkstückes.ίο means compared to previous procedures a significant simplification and thus a considerable reduction in the cost of the workpiece.

Bisher wurde nämlich zunächst zwischen zwei symmetrischen Vormatrizen ein Zwischenkörper gepreßt, der alsdann in eine besondere Untermatrize gebracht werden mußte, in welcher ein besonderer Stempel die Pressung vollendete. Bei dem vorliegenden Verfahren ist dagegen nur eine einzige Untermatrize er-, forderlich, in welcher sowohl die Vorpressung ao als auch die Fertigpressung erfolgt. Die Abweichung gegenüber dem bekannten Verfahren ist also besonders darin zu sehen, daß bei diesem das Preßstück zwischen den beidenSo far, namely, an intermediate body was initially between two symmetrical pre-dies pressed, which then had to be brought into a special lower die, in which a special punch did the pressing completed. In the present process, on the other hand, only a single sub-die is required, Required, in which both the pre-pressing ao and the final pressing takes place. The deviation compared to the known method is therefore particularly to be seen in the fact that in this case the pressed piece between the two

symmetrischen Vormatrizen nur allgemein vorgearbeitet wird, also noch nicht die bewußte Übergangsform zu dem fertigen Radkörper annimmt. Infolgedessen sind besondere Werkzeuge, sowohl Untermatrize als Stempel, zur Fertigpressung erforderlich.symmetrical pre-matrices are only generally prepared, so not the conscious one Assumes transition shape to the finished wheel center. As a result, special tools, both sub-die and Stamp, required for final pressing.

Zur Ausführung des Verfahrens kann vorzugsweise eine bekannte Vorrichtung mit zweiteiliger Matrize dienen, deren TeileA known device can preferably be used to carry out the method two-part die, the parts of which are used

ίο achsial gegeneinander verschiebbar sind, wobei der Erfindung gemäß das Bodenstück der Matrize nach unten denkbar ist.ίο are axially displaceable against each other, whereby according to the invention, the bottom piece of the die down is conceivable.

In Abb. ι ist α der Block und b der einzige. Vorpreßstempel, der den Block in die untere Matrize k mit der den Boden bildenden Fertigmatrize e hineinpreßt, wodurch der Block die in Abb. 2 dargestellte Form erhält. Nunmehr wird der Vorpreßstempel b beseitigt und der Fertigstempel m niedergesenkt, derIn Fig. Ι, α is the block and b is the only one. Prepressing punch which presses the block into the lower die k with the finished die e forming the bottom, whereby the block is given the shape shown in Fig. 2. Now the prepress ram b is eliminated and the finishing ram m is lowered, the

so die Pressung vollendet und den äußeren Wulstring d in den Hohlraum für den Laufkranz hineinpreßt. In dem Fertigstenipel können am Rande radiale Einschnitte« vorgesehen sein, durch die beim Pressen die Rippen 0 des Rades geformt werden (Abb. 4). Der Fertigpreßstempel η paßt auf den oberen Teil des Vorpreßstempels b, so daß dieser nur seitlich herausgenommen zu-werden braucht, worauf man sogleich den Fertigstempel niedersenken kann.so the pressing is completed and the outer bead ring d presses into the cavity for the tread. In the prefabricated nipple, radial incisions can be provided on the edge through which the ribs 0 of the wheel are formed during pressing (Fig. 4). The finishing punch η fits onto the upper part of the prepressing punch b, so that it only needs to be removed from the side, whereupon the finishing punch can be lowered immediately.

Das Bodenstück e der Matrizen k ist gegen diese achsial beweglich, und zwar nach unten durch Verschiebung der Keile g senkbar, so daß das fertige Werkstück nach dem Senken des Bodens seitlich herausgenommen werden kann.The bottom piece e of the matrices k is axially movable against this, namely downward by shifting the wedges g , so that the finished workpiece can be removed laterally after the bottom has been lowered.
