Patentiert im Deutschen Reiche vom 7. Februar 1906 ab.Patented in the German Empire on February 7, 1906.

Gegenstand der Erfindung ist eine Druckwasserpresse mit Druckstufen. Das Neue besteht im wesentlichen darin, daß die Erzielung der Druckstufen durch auswechselbare, mit dem Tauchkolben der Presse zusammenwirkende Kolben erfolgt.The invention relates to a pressurized water press with pressure stages. The new consists essentially in that the achievement of the pressure levels by exchangeable, piston cooperating with the plunger of the press takes place.

Als Beispiel ist in der Zeichnung eine sonst bekannte Druckwasserpresse mit Dampfbetrieb in drei Ausführungsformen der ErfindungAs an example, the drawing shows an otherwise known pressurized water press with steam operation in three embodiments of the invention

The invention can, however, analogously also at any other press, e.g. B. such with a pulling effect as well as any pressurized water cylinder used will.

Fig. ι zeigt die erste Ausführungsform, welche die einfachste Form der auswechselbaren Kolben, nämlich mit dem Tauchkolben der Presse festverbundene Stangen, darstellt. Es ist α der Dampfzylinder, b der Dampfkolben, c die Dampfkolbenstange mit der Ausbohrung d und e der Rohrleitungsanschluß an die eigentliche Presse, f ist die Stopfbüchse und g, g¹, g² sind auswechselbare Kolben, welche verschiedenen Durchmesser haben. Es ist nun ohne weiteres klar, daß bei Verwendung des Kolbens g Druckwasser von sehr hoher Pressung, mit dem Kolben g¹ Druckwasser von mittlerer Pressung und mit dem Kolben g²· solches von noch geringerer, und, falls man ganz ohne den auswechselbaren Kolben arbeiten würde, solches von geringster Pressung erzeugt wird. Selbstverständlich ist jede beliebige Zwischenstufe erreichbar. In Anwen-Fig. Ι shows the first embodiment, which represents the simplest form of the exchangeable piston, namely rods firmly connected to the plunger of the press. It is α the steam cylinder, b the steam piston, c the steam piston rod with the bore d and e the pipe connection to the actual press, f is the stuffing box and g, g ¹ , g ² are interchangeable pistons with different diameters. It is now immediately clear that when using the piston g pressurized water of very high pressure, with the piston g ¹ pressurized water of medium pressure and with the piston g ^{2 that} of even less, and if one works entirely without the replaceable piston would, such is generated by the lowest pressure. Of course, any intermediate level can be achieved. In application

dung auf einen Wasserdruckpreßzylinder würde man z. B. mit einem Drittel, zwei Dritteln oder mit dem gesamten Druck arbeiten können, entsprechend ^!/_s, ²/₃ und vollem Druckwasserverbrauch. Auch hierbei ist natürlich jede andere Abstufung ohne Schwierigkeiten zu erzielen. In Anwendung auf einen Kraftsammler kann man in einfachster Weise z. B. die Druckstufen 50, 100 und 150 Atmosphären erhalten, eine Abstufung, die bei der bekannten Dreiteilung des Querschnitts, gemäß dem Gesetz der natürlichen Zahlenreihe, ganz unmöglich zu erreichen ist. Auch hierbei steht jeder beliebigen Abstufung, auch nachträglichen, nichts im Wege.manure on a water pressure cylinder you would z. B. can work with a third, two thirds or with the entire pressure, accordingly ^! / _S, ^_2/3 and full pressure water consumption. Here, too, any other gradation can of course be achieved without difficulty. In application to a force collector you can in the simplest way z. B. obtain the pressure levels 50, 100 and 150 atmospheres, a gradation that is quite impossible to achieve with the known three-way division of the cross-section, according to the law of the natural series of numbers. Here, too, nothing stands in the way of any gradation, even afterwards.

Bei der zweiten Ausführungsform (Fig. 2) ist der auswechselbare Kolben mit einem in den Hohlraum d passenden verdickten Ende/z versehen. Beim Arbeiten mit dem Kolben g wird zunächst auf einem durch die Länge des verdickten Endes h bestimmten Wege Hochdruck erzeugt. Sobald die Kolbenstange c so hoch gegangen, ist, daß das verdickte Ende h vom Kolben g den Boden des Hohlraumes d berührt, geht auch der KoI-ben g mit hoch, und es wird nun Druckwasser von niedrigerer Spannung erzeugt, und zwar in entsprechend größerer Menge, so daß, z. B. für Werkzeugmaschinen, beim Schneiden mit abnehmendem Widerstände im Preßzylinder bei gleichem Kraftmittelaufwande ein größerer Weg zurückgelegt wird. Bei dieser Ausführungsform muß die Luft aus demIn the second embodiment (FIG. 2), the replaceable piston is provided with a thickened end / z that fits into the cavity d. When working with the piston g , high pressure is first generated on a path determined by the length of the thickened end h. As soon as the piston rod c been so high, that the thickened end h of the piston g the bottom of the cavity contacts d, is also the KOI-ben g with high and it is now pressurized water generated by a lower voltage, and higher, although in accordance with Amount so that, e.g. B. for machine tools, when cutting with decreasing resistances in the press cylinder with the same expenditure of force, a greater distance is covered. In this embodiment, the air from the

Cavity d can exit and enter, for which purpose the piston g is pierced. Pistons g ^l and g ² have elongated thickened ends h ^l and h ² ; when they are used, the path under high pressure becomes shorter by the length of each. If the length of the thickened end is equal to the length of the bore d, only low pressure can arise. These can be made even easier

ίο Achieve gradations if you make the piston g up long enough to be able to lower it down to the desired gradation.

If the thinner end of the piston is changed in this embodiment, as indicated by dotted lines in g ¹ , g ' ² , then at the same time graduations in the pressure levels are obtained in the same way as in the first embodiment.

Fig. 3 shows the same pistons g, g ¹ , g ² of different lengths of the thickened ends h, h ¹ , h ² , as in Fig. 2, but in a firmly pulled-up position. Here, press water of low pressure is first generated on a path corresponding to the distance between the piston g and the piston rod c, which z. B. for filling so-called dead paths for prepressing o. The like. Is important. As soon as the sealing of the thickened ends h, h ¹ , h ^{2 reaches} the bore d of the piston rod c , the further path results in press water of correspondingly high pressure. By varying the length of the piston thickening h, h ¹ , h ² , the pressure change can be shifted to any point of the stroke. If you change the thickness and at the same time place the appropriate bushings in the bore d, you can also graduate the high pressure as you wish. Since in this embodiment part of the press water is intercepted by low pressure, it must be able to escape from the bore d during the generation of high pressure water. Various means can be used for this, for example also, as shown, a loaded valve i .

The following different ways of using the interchangeable pistons result: .1. Slidable rod of various thicknesses firmly connected to the plunger for high, medium and low pressure in any gradation (Fig. 1).

2. Slidable rod with a fitting in the cavity d and also displaceable therein thickened end of various lengths for the production of z. B. ^_3/4 hypertension and Y ₄ low pressure or Y ₂ high pressure ^and] / ₂ low-pressure or Y ₃ high pressure and ^{_2/3 of} depression, or only low pressure, whereby any gradation möglieh (Fig. 2).

3. Slidable rod of various thicknesses with a thickened end of various lengths that fits into the cavity d and can also be displaced therein (connection of ι and 2).

4. Raised bar with thickened end of different lengths to produce approximately Y ₄ Low Pressure and ^_3/4 hypertension or Y ₂ and low. Depending on the operating conditions make any arbitrary gradation Y ₂ High Pressure or ^{_2/3 of} low and high pressure Y ₃ or even high pressure is required.

5. The same as in 4, but the interchangeable pistons of different thicknesses, so connection of 1 and 4.
