KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Rohren beliebiger Querschnittsform, welche an beliebigen Stellen, beispielsweise an den Enden oder in der Mitte, gröfsere Wandstärke als an anderen Stellen haben sollen.The present invention relates to a method for producing pipes of any cross-sectional shape, which at any point, for example at the ends or in the middle, have greater wall thickness than at other points should have.
Dieses Verfahren besteht im Wesentlichen darin, dafs ein Blechstreifen, dessen Dicke gleich jener der stärksten Stelle des fertigen Rohres ist und dessen Breite dem Rohrumfang oder einem Vielfachen desselben entspricht, vorerst durch Walzarbeit an den zwischen den oder beiderseits der stärker zu belassenden Stellen in seiner Dicke auf die verlangte Wandstärke des Rohres gebracht wird, worauf der derart an verschiedenen Stellen verschieden starke Streifen bezw. die nach dem Zerschneiden der Tafel erhaltenen Streifen über einen Dorn zusammengerollt und an den Längskanten verbunden werden.This method consists essentially in the fact that a sheet metal strip, its thickness equal to that of the thickest point of the finished pipe and its width to the pipe circumference or a multiple thereof, initially by rolling the between the or on both sides of the areas to be left stronger in its thickness to the required wall thickness of the pipe is brought, whereupon the so different in different places strong stripes resp. the strips obtained after cutting the panel over a mandrel rolled up and connected at the long edges.
Beiliegende Zeichnung veranschaulicht die auf einander folgenden Arbeitsstadien, welche das Werkstück bei Durchführung des Verfahrens durchzumachen hat.The accompanying drawing illustrates the successive stages of work, which the workpiece has to go through when performing the procedure.
Fig. ι zeigt einen Blechstreifen a, dessen Wandstärke gleich der Dicke des herzustellenden Rohres an den verstärkten Enden oder dem verstärkten Mitteltheil desselben ist, während die Breite der Umfangslänge des Rohres entspricht.Fig. Ι shows a sheet metal strip a, the wall thickness of which is equal to the thickness of the pipe to be produced at the reinforced ends or the reinforced middle part of the same, while the width corresponds to the circumferential length of the pipe.
Durch Auswalzen in der Längsrichtung wird der Streifen α derart faconnirt, dafs er entweder, wie in Fig. 2, an den Enden (bei al) oder, wie in Fig. 3, in der Mitte (bei a2) seine ursprüngliche Stärke behält, während der übrige Theil zwischen den Enden oder beiderseits der Mittelstelle auf die gewünschte Rohrwanddicke reducirt wird.By rolling out in the longitudinal direction, the strip α is shaped in such a way that it retains its original thickness either, as in Fig. 2, at the ends (at a 1 ) or, as in Fig. 3, in the middle (at a 2 ) , while the remaining part between the ends or on both sides of the middle point is reduced to the desired tube wall thickness.
Die derart erhaltenen Streifen werden über einen Dorn zusammengerollt und ihre über oder neben einander liegenden Längskanten durch Löthen mit einander verbunden, wodurch ein Rohr von beliebigem Querschnitt: rund, oval, halbrund etc., je nach dem Profil des Domes, erhalten wird, welches Rohr entweder an den Enden, wie nach Fig. 4, oder in der Mitte, wie nach Fig. 5, stärker als an den übrigen Stellen ist.The strips thus obtained are rolled up over a mandrel and their over or adjacent longitudinal edges connected to one another by soldering, whereby a tube of any cross-section: round, oval, semicircular, etc., depending on the profile of the dome, which tube is either at the ends, as in FIG. 4, or in the middle, as shown in FIG. 5, is stronger than in the other places.
Anstatt des Streifens kann auch eine Tafel (Fig. ia), deren Breite gleich einem Vielfachen der Streifenbreite ist, durch das W7alzen faconnirt werden, wie dies beispielsweise Fig. 2a zeigt, worauf diese Tafel in für je ein Rohr passende Streifen α zerschnitten wird, welche in früher beschriebener Weise zu Rohren weiter verarbeitet werden.Instead of the strip, a panel (Fig. Ia), the width of which is equal to a multiple of the strip width, can be shaped by the W 7 alzen, as shown, for example, in Fig. 2a, whereupon this panel is cut into strips α that fit each tube which are further processed into tubes in the manner described earlier.
