Bei eisernen Rohren für Wärmeaustauschzwecke ist es in gewissen Fällen, z.

Metall, wie Kupfer, auszulegen. Soll dieses Ausfüttern mit hoherwertigem Metall auf rein mechanischem Wege durch inniges Aufeinanderpressen beider Metallschichten geschehen, so ist, um nicht die Wärmeaus-Metal, such as copper. Should this lining up with high quality metal purely mechanically by pressing both metal layers closely together, so as not to
tauschfähigkeit zu beeinträchtigen, besondere Sorgfalt darauf zu legen, daß die einander zugekehrten Mantelflächen der beiden Metallschichten vollkommen rein und die Rohre selbst im Querschnitt rund und von Unebenheiten frei sind. Insbesondere aber die im Handel erhältlichen Eisenrohre bedürfen in dieser Hinsicht einer besonderen Vorbereitung, da sie erfahrungsgemäß meist unrund,To impair exchangeability, special care must be taken to ensure that each other facing lateral surfaces of the two metal layers completely clean and the pipes even in cross-section are round and free of unevenness. But especially the im Commercially available iron pipes require special preparation in this regard, as experience has shown that they are usually out of round,
ίο uneben und verunreinigt sind.ίο are uneven and contaminated.
Die Erfindung bezieht sich auf ein Werkzeug, welches zugleich mit dem genauen Runden des Rohrinnenf auch das Glätten und Reinigen von Oxyden usw. in einem Arbeits-Vorgang ermöglicht.The invention relates to a tool, which at the same time with the precise rounding the inside of the pipe also smoothing and cleaning of oxides etc. in one operation enables.
Das Werkzeug besteht in einem durch das Rohr zu treibenden kegeligen Dorn an und für sich bekannter Art, mit der Neuerung jedoch, daß der Dorn in seinem mittleren Teile mit Schabekanten ausgestattet ist.The tool consists of a conical mandrel to be driven through the pipe on and of a known kind, with the innovation, however, that the thorn is in its middle Parts is equipped with scraper edges.
In der Zeichnung ist ein Ausführungsbeispiel eines solchen kegeligen Domes dargestellt, und zwar in der Abb. ι in Ansicht, in den Abb. 2 und 3 in zwei Schnitten. In dem mittleren Teile m des Domes sind Nuten η und Schabekanten s angeordnet. Der Dorn ist beim Durchtreiben durch das vorzubereitende Rohr, was z. B. mittels einer durch die Bohrung c geführten Zugstange erfolgen kann, in Drehung zu versetzen, um die Schabekanten s wirken zu lassen. Die Wirkung des ganzen Werkzeuges ist so, daß der vordere Teil ν des Domes von etwas geringerem Querschnitt die groben Unebenheiten des Rohrquerschnittes ausgleicht und die genaue Rundung vornimmt, worauf die Schabekanten die Beseitigung von Schmutz und Oxyden bewirken, und endlich der hintere Teil h von etwas stärkerem Querschnitt die Glättung vollzieht. Der vordere und hintere kantenlose Teil ν und h dienen zugleich den Schabekanten s als Schutz gegen zu große Beanspruchung auf Druck und damit gegen vorzeitige Abnutzung und Schartenbildung.In the drawing, an embodiment of such a conical dome is shown, in the Fig. Ι in view, in Figs. 2 and 3 in two sections. In the middle part m of the dome grooves η and scraper edges s are arranged. The mandrel is when driving through the pipe to be prepared, which z. B. can be effected by means of a through bore c guided tie rod in rotation, in order to let the scraping function s. The effect of the whole tool is such that the front part ν of the dome with a slightly smaller cross-section compensates for the rough unevenness of the pipe cross-section and makes the exact rounding, whereupon the scraping edges cause the removal of dirt and oxides, and finally the rear part h of something with a thicker cross-section, the smoothing takes place. The front and rear edgeless parts ν and h also serve the scraping edges s as protection against excessive stress on pressure and thus against premature wear and tear and notch formation.
Die Schabekanten können auch in Gestalt steilgängigen Gewindes angeordnet sein, in welchem Falle eine drehende Bewegung des Domes beim Durchziehen durch das Rohr nicht erforderlich ist.The scraper edges can also be arranged in the form of a steep thread in which case a rotating movement of the dome when pulling through the pipe is not required.
