Description

Die vorliegende Erfindung betrifft eine besonders vorteilhafte Gestaltung von aus Blech bestehenden Druckmittelbehältern, wie sie z. B. bei Druckluftbremsen vielfach gebraucht werden. Diese Behälter setzten sich bisher aus einem zylindrischen. durch eine Schweiß-Längsnaht zusammengehaltenen Teil und den auf dessen beiden Enden aufgeschweißten flachgewölbten Deckeln zusammen, wobei die Blechst*irke an allen Stellen die gleiche ist. Das letztere Merkmal bedeutet, z. B. insbesondere an den Stellen der Schweißnähte, einen wesentlichen Nachteil in festigkeitsmäßiger Hinsicht. Demgegenüber ist es Aufgabe der vorliegenden Erfindung, einen aus Blech bestehenden Druckmittelhehälter so zu gestalten, daß er in seiner Festigkeit keine kritischen Stellen mehr aufweist. Dies wird erfindungsgemäß dadurch erreicht, daß der Druckmittelbehälterinfolge entsprechender Blechformung an der Stelle größerer Beanspruchung eine größere Wandstärke aufweist. Der weiteren Erfindung gemäß wird der Druckmittelbehälter vorteilhaft aus durch Schweißung miteinander verbundenen Hohlkörpern gestaltet, deren Wandü -e im Gebiet der Schweißnaht größer ist als s 'irl, an den anderen Stellen. Die Herstellung dieser Hohlkörper als Gebilde, welche jeweils aus einem annähernd zylindrischen, gegen sein offenes Ende zunehmende Wandstärke aufweisenden. Teil und einem mit dem letzteren ein Stück bildenden halbkugeligen Teil bestehen, ist in vorteilhafter Weise im Ziehverfahren möglich, wobei der Unterschied zwischen dem Außendurchmesser des Ziehwerkzeuges und dem Innendurchmesser des Gesenkes größer gewählt wird als die Stärke des zu ziehenden Bleches, so daß eilte Wandreckung vermieden ist.The present invention relates to a particularly advantageous design of existing sheet metal pressure medium containers, as they are, for. B. with air brakes are used many times. These containers have so far consisted of a cylindrical one. part held together by a longitudinal weld seam and the part on both ends welded flat-arched lids together, with the sheet metal thickness on all Make is the same. The latter feature means e.g. B. in particular to the Place the welds, a major disadvantage in terms of strength. In contrast, it is the object of the present invention to provide a sheet metal Design pressure fluid container so that it is not critical in terms of strength Has more places. This is achieved according to the invention in that the pressure medium container as a result corresponding sheet metal forming a greater wall thickness at the point of greater stress having. According to the further invention, the pressure medium container is advantageous designed from hollow bodies connected to one another by welding, the wall of which -e is larger in the area of the weld than s'irl, in the other places. the Production of these hollow bodies as a structure, each of which consists of an approximately cylindrical, having increasing wall thickness towards its open end. Part and one with the the latter consisting of a hemispherical part forming a piece is more advantageous Way possible in the drawing process, with the difference between the outer diameter of the drawing tool and the inner diameter of the die is chosen larger than the strength of the sheet to be drawn, so that hasty wall stretching is avoided.

In Abb. i der Zeichnung ist ein Druckluftbehälter für eine Bremsanlage gezeigt, der aus den beiden Hohlkörpern i und 3 besteht. Diese beiden Hohlkörper sind so gestaltet, daß die Wandstärke des Behälters an der Stelle der stärksten Beanspruchung, also im Gebiet der verbindenden Schweißraupe 5, z. B. um o,5 min größer ist als an der Stelle kleinster Wandstärke (diese Zunahme ist in der Abbildung übertrieben dargestellt). Damit ist der nur mit etwa o,; der im übrigen zulässigen Belastung einzusetzende Festigkeitswert der Schweißstelle durch die stärkere Dimensionierung praktisch ausgeglichen. In der Abb. i fällt weiter auf, daß bei dein neuen Behälter die Längsnaht der bisherigen Ausführungen, die bekanntlich nur mit 50% des Belastungswertes einer Rundnaht belastet «erden darf, überhauet weggefallen ist (die drei Schweißnähte der bekannten Ausführung sind auf eine Rundnaht vermindert), und daß außerdem die Enden des Behälters in der festigkeitsmäßig günstigsten Form der Halbkugel ausgebildet sind.In Fig. I of the drawing is a compressed air tank for a brake system shown, which consists of the two hollow bodies i and 3. These two hollow bodies are designed so that the wall thickness of the container at the point of the strongest Stress, so in the area of the connecting weld bead 5, z. B. at 0.5 min is greater than at the point of the smallest wall thickness (this increase is in the figure exaggerated). So that is only with about o; the otherwise permissible Strength value of the weld point to be applied due to the larger dimensioning practically balanced. In Fig. I it is also noticeable that with your new container the longitudinal seam of the previous designs, which is known to only be 50% of the load value a circumferential seam "may be grounded, has been hewn away (the three weld seams the known design are reduced to a round seam), and that also the Ends of the container in the form of the hemisphere which is most favorable in terms of strength are.

Die Hohlkörper i und 3 werden zur Erzielung a11 dieser Merkmale vorteilhaft im Ziehverfahren hergestellt, wobei die Ziehvorrichtung, wie Abb. z zeigt, erfindungsgemäß so dimensioniert ist, daß der Unterschied zwischen dem Außendurchmesser dl des Ziehwerkzeuges i und dem Innendurchmesser d., des Gesenkes ;1 größer ist als die Stärke »s« des zu ziehenden Bleches 13. Damit ist eine Reckung vermieden, und es ergibt sich die aus Abb. i ersichtliche Zunahme der Wandstärke der Hohlkörper im Gebiet der Schweißnaht 5. Die Gesamtform der Hohlkörper (durch welche auch die Verminderung der Schweißnähte bis auf eine Rundnaht ermöglicht ist) gestattet schließlich in einem einfachen Vorgang und ohne Verschnitt das Ziehen der Halbkugelforni der geschlossenen Enden.The hollow bodies i and 3 are advantageous to achieve a11 of these features produced in the drawing process, the drawing device, as Fig. z shows, according to the invention is dimensioned so that the difference between the outer diameter dl of the drawing tool i and the inside diameter d., of the die; 1 is greater than the thickness "s" of the sheet to be drawn 13. This avoids stretching, and the result is the increase in the wall thickness of the hollow bodies in the area of the weld seam that can be seen in Fig. i 5. The overall shape of the hollow body (through which also the reduction of the weld seams except for a circular seam is possible) finally allowed in a simple process and without waste, the hemispherical shape of the closed ends is drawn.
