Description

Bei Pressen zum Lochen von Metallblöcken erfolgt bisher die Kühlung der Matrize α und des Lochdorns b nach Fig. ι durch einen mit Spritzlöchern c versehenen Hohlring d, welcher mittels Schlauches e an die Wasserleitung angeschlossen ist.For presses for punching metal blocks so far the cooling of the die is α and the piercing mandrel b of FIG. Ι c by a spray holes provided with hollow ring d, which is connected to the water line by means of the tube e.

Die nachstehend beschriebene Erfindung bezweckt den, den Lochdorn b umgreifenden Vorpreß-Stempel f für die Kühlung der Matrize α und des Lochdorns b nutzbar zu machen. Zu diesem Zweck wird naeh den Fig. 2 und 3 der untere volle Teil des Vorpreß-Stempels f mit Ablauflöchern g versehen und der Schlitz h durch einen leicht handlichen Schieber i o. dgl. derart abgeschlossen, daß durch die an den Vorpreß-Stempel mittels elastischen Schlauches k angeschlossene Wasserleitung das Kühlwasser im Hohlraum ansteigen The invention described below is intended to, the piercer b encompassing preforming punch f α for the cooling of the die and the mandrel hole b to make it usable. For this purpose, the lower full part of the prepress ram f is provided with drainage holes g and the slot h by an easy-to-use slide i o elastic hose k connected water pipe the cooling water rise in the cavity
