Abstract

The radiator has a number of parallel tubes and on each end the radiator has transverse collecting headers. The production process enables these radiators to be built in a simple manner in any required length. The ends of the parallel tubes are placed into holes made into two sheet metal strips. A guide collar may be inserted in the holes. The tubes are joined to these plates and the sheet metal strips are subsequently formed so that when the edges are joined it forms a collecting header of polygonal cross section. The tubes are joined to the end headers and the ends of the tubes are held by the collars formed into the initial sheet metal strip.

Verfahren zur Herstellung eines RöhrenradiatorsProcess for the manufacture of a tubular radiator

Die Erfindung betrifft ein Verfahren zur Herstellung eines Röhrenradiators, der aus mehreren Querrohren und zwei an den Enden derselben angeschlossenen, senkrecht zu ihnen verlaufenden Sammelrohren besteht.The invention relates to a method for producing a tubular radiator, that of several cross tubes and two header tubes connected at the ends thereof and running perpendicular to them consists.

Die Röhrenradiatoren der obengenannten Art wurden bisher so hergestellt, dass in Vier- oder Sechskantrohre, die als Sammelrohre dienen, Löcher eingebohrt werden, in welche Rundrohre eingesetzt und mit den Mehr kan tr ohr en zusammengeschv/eisst werden. Es ist auch ein Verfahren bekannt, bei welchem anstatt durch Verschweissen der Rundrohre mit den Mehrkantrohren die Verbindung der beiden Rohre durch Einlöten hergestellt wird, wonach sie feuerverzinkt werden.The tubular radiators of the above type have been manufactured so far, that in square or hexagonal tubes, which serve as collecting tubes, holes are drilled into which round tubes are inserted and can be welded together with the multiple tubes. It is also known a method in which instead of welding The connection of the two tubes is made by soldering the round tubes with the polygonal tubes, after which they are hot-dip galvanized will.

Fall 1case 1

Solche Herstellungsverfahren verlangen einen verhältnisraässig gros~ sen Anteil an Handarbeit. Weil die Mehrkantrohre in Lagerlängen lieferbar sind, können aus denselben keine Heizkörper von beliebiger Länge vollautomatisch hergestellt werden. Wenn schon die Erfordernisse des Marktes in Bezug auf Längen erfüllt werden können, ist der Rohmaterialabfall sehr gross. Ausserdem müssen bei den bekannten Herstellungsverfahren zeitraubende Handabgratoperationen vorgenommen werden.Such manufacturing processes require a relatively large ~ sen share of manual labor. Because the polygonal tubes are available in stock lengths, no radiators of any arbitrary can be made from them Length can be produced fully automatically. If the requirements of the market in terms of lengths can be met, is the raw material waste is very large. Also have to be with the well-known Manufacturing processes time-consuming manual trimming operations are made.

Der Erfindung liegt die Aufgabe zugrunde, die obenerwähnten Nachteile zu vermeiden und ein Herstellungsverfahren eines Röhrenradiators zu stellen, in welchem ohne Beeinträchtigung der Wirtschaftlichkeit die Röhrenradiatoren auf eine einfache Weise in gewünschten Längen hergestellt werden, wobei zeitraubende Handoperationen auf das Minimum herabgesetzt werden.The invention is based on the above-mentioned disadvantages to avoid and to provide a manufacturing method of a tubular radiator in which without impairing the economy the tubular radiators can be manufactured in a simple manner in the desired lengths, with time-consuming manual operations be reduced to the minimum.

Erfindungsgeraäss ist das Verfahren zur Herstellung eines Röhrenradiators dadurch gekennzeichnet, dass die Enden der Querrohre.in Löcher mit oder ohne vorgezogene Kragen von zwei Blechbändern eingeführt und mit denselben fest verbunden werden, wonach die Blechbänder derart verformt werden, dass sie nach der Pestverbindung ihrer Ränder die Mehrkantsammelrohre bilden.The device of the invention is the method for manufacturing a tubular radiator characterized in that the ends of the Querrohre.in holes with or without protruding collars of two sheet metal strips and are firmly connected to the same, after which the sheet metal strips are deformed in such a way that they are after the plague connection their edges form the polygonal manifolds.

Die Erfindung wird nachstehend anhand von Zeichnungen beispielsweise näher erläutert. Es zeigen:The invention is described below with reference to drawings, for example explained in more detail. Show it:

Wie aus den Pig. 1 bis 6 ersichtlich ist, werden die Rö'hrenradiatoren von beliebiger Länge vollautomatisch hergestellt. Blechbänder 2 werden gelocht und Kragen 4 gezogen. Das Blechband 2 wird dann vorgewalzt. Einzelne Querrohre 1, die im Querschnitt z.B. kreisförmig sind, werden in die Löcher 3 der Blechstreifen 2 eingesetzt, bis ihre Enden mit den Rändern der Kragen 4 fluchten. Dann werden sie mit den Kragen 4 verschweisst. Durch Walzen werden die Blechbänder 2 zu fertigen Mehrkantsammelrohren weiterverformt, wonach im Falle der zur Längsachse des Querrohres 1 unsymmetrisch angeordneten Randteile der Blechbänder 2 dieselben vorzugsweise im Rollennaht schwei ssen miteinander fest verbunden werden. Im Falle der zur Längsachse des Querrohres symmetrisch angeordneten Randteile der Blechbänder 2 (siehe die Fig. 5 und 6) werden dieselben miteinander vorzugsweise durch. Induktionsschweissen fest verbunden.Like from the Pig. 1 to 6 are the tubular radiators of any length produced fully automatically. Sheet metal strips 2 are perforated and collars 4 are drawn. The sheet metal strip 2 is then pre-rolled. Individual transverse tubes 1, which are e.g. circular in cross-section, are inserted into the holes 3 of the sheet metal strips 2, until their ends are flush with the edges of the collar 4. Then they are welded to the collar 4. The sheet metal strips are rolled 2 further deformed into finished multi-sided manifolds, after which in the case of the edge parts of the sheet metal strips 2 arranged asymmetrically to the longitudinal axis of the cross tube 1, the same preferably in the roll seam welds are firmly connected to each other. In the case of the edge parts of the symmetrically arranged to the longitudinal axis of the cross tube Sheet metal strips 2 (see FIGS. 5 and 6) are preferably through the same with one another. Induction welding firmly connected.

Der fertige Radiator ist in der Fig. 7 in Teildraufsicht dargestellt. Mehrere Querrohre 1 werden auf die obenbeschriebene Weise in einem vollautomatischen Herstellungsverfahren in zwei senkrecht zu ihnen verlaufende Mehrkantsammelrohre, die aus je einem einzigen Stück des Blechbandes 2 geformt werden, eingebettet.The finished radiator is shown in FIG. 7 in a partial plan view. Several cross tubes 1 are vertically in the manner described above in a fully automatic manufacturing process in two to them extending polygonal collecting pipes, which are each formed from a single piece of the sheet metal strip 2, embedded.

Es besteht auch die Möglichkeit, dass die Enden der Querrohre 1 mit zwei Blechbändern 2 auf solche Art verbunden werden, dass sie in ihren Löchern, die mit keinem Kragen versehen sind, eingelötet werden.There is also the possibility that the ends of the cross tubes 1 are connected with two sheet metal strips 2 in such a way that they soldered in their holes, which are not provided with a collar will.

Die Vorteile des oben beschriebenen Verfahrens bestehen unter anderem darin, dass die Handarbeit sowie der Rohmaterialabfall sehr gering ist. Die Röhrenr.adiatoren brauchen in nicht notwendigerweise vom Verfahren her gegebenen Längen hergestellt werden. Das zur Herstellung des Sammelrohres verwendete Blech ist ein gewöhnliches Blech, ohne spezielle Tiefziehqualität.The advantages of the method described above are among others in that the manual labor as well as the waste of raw materials is very little. The tubular radiators do not necessarily need it lengths given by the process. The sheet metal used to manufacture the manifold is ordinary Sheet metal, without special deep-drawing quality.

Der in diesem Verfahren hergestellte Röhrenradiator kann als Röhrenrad verwendet, oder zum Eonvektor bzw. zur Heizwand ergänzt werden, wobei eine horizontale oder vergikale Montage möglich ist. Br weist eine überdurchschnittliche Wärmeabgabe auf.The tubular radiator produced in this process can be used as a tubular wheel used, or added to the Eonvektor or to the heating wall, whereby a horizontal or vergical mounting is possible. Br has an above-average heat emission.
