Description
Verfahren zur Herstellung von schmiedeeisernen, winkelförmigen Rohrverbindungsstücken Gegenstand der Erfindung bildet eine Vereinfachung des Verfahrens nach Patent 4.73 095. Das in der Patentschrift 473 095 dargestellte Rohrverbindungsstück besteht aus dem Durchgangsstück a, dem Stutzen b und den vier keilförmigen Blechstücken c. Die Blechstücke c werden in die vier keilförmigen Öffnungen eingeschweißt und müssen vorher einzeln den Öffnungen genau angepaßt werden; außerdem sind die Enden der Lappen e vor dem Anschweißen flachzudrücken.Process for the production of wrought-iron, angular pipe connectors The object of the invention is a simplification of the process according to Patent 4.73 095. The pipe connector shown in Patent 473 095 consists of the passage piece a, the socket b and the four wedge-shaped sheet metal pieces c. The sheet metal pieces c are welded into the four wedge-shaped openings and must be individually adapted to the openings beforehand; In addition, the ends of the tabs e are to be pressed flat before welding.
\ach der vorliegenden Erfindung sollen die vier Blechstücke durch nur zwei BlechstÜcke ersetzt werden, nachdem die beiden Lappen e (Abb. 3 und 4.) abgeschnitten sind. Hierdurch fällt das Flachdrücken der Lappen e fort und statt der vier brauchen nur zwei Blechstücke angepaßt und verschweißt werden. Die Herstellung des Rohrverbindungsstückes ist hierdurch eine viel schnellere, und infolgedessen sind die Herstellungskosten erheblich geringer.According to the present invention, the four pieces of sheet metal should go through only two pieces of sheet metal are replaced after the two tabs e (Fig. 3 and 4.) are cut off. As a result, the flattening of the flaps e ceases to exist and takes place of the four only need two pieces of sheet metal to be adapted and welded. The production of the pipe connector is hereby much faster, and consequently the manufacturing costs are significantly lower.
In der Zeichnung ist das schmiedeeiserne Rohrverbindungsstück in Abb. r und 2 dargestellt. Abb. I zeigt einen Längsschnitt, während Abb. 2 eine Ansicht von vorn darstellt. Die Abb. 3 bis 5 zeigen den Abzweigstutzen während verschiedener Stufen des Herstellungsverfahrens.In the drawing, the wrought iron pipe connector in Fig. r and 2 shown. Fig. I shows a longitudinal section, while Fig. 2 shows a view from the front. Figs. 3 to 5 show the branch pipe during various Stages of the manufacturing process.
Das dargestellte -f-Stü ck besteht aus dem Durchgangsstück a, dem Stutzen b und den zwei Blechstücken c. Bei der Herstellung wird in das Durchgangsstück a ein längliches Loch geschnitten, auf dessen Rand der Stut-zen b und die beiden Blechstücke c aufgeschweißt werden sollen und dessen Länge sich nach der gewünschten Größe des Bogens an den Lappen d richtet. Der Stutzen b (Abb. 3 und 4.) wird an vier Stellen in der Längsrichtung so weit aufgeschnitten, als es die Größe bzw. der Radius des herzustellenden Bogens an den Lappen d erfordert. Von den entstehenden vier Lappen werden die beiden gegenüberliegenden, in Längsrichtung des Durchgangsstutzens verlaufenden Lappen e abgeschnitten, so daß zwei viereckige Öffnungen entstehen. Die vier Einschnitte können aber in dem Stutzen b auch so angebracht werden, daß die entstehenden Öffnungen eine beliebige andere Form, z. B. eine spitzwinkelige, aufweisen. Die beiden stehengebliebenen Lappen d werden nun in einem Gesenk in dem gewünschten Maße gebogen (Abb. 5). Nach dem Aufschweißen des Stutzens b, d. h. seiner beiden Lappen d, auf das Durchgangsstück a bleiben an der vorderen und hinteren Fläche des Stutzens noch zwei Öffnungen frei, in die Blechstücke c von der Wandstärke der Rohre eingeschweißt werden. Sämtliche Wandstärken, auch die der Lappen d, bleiben unverändert, denn es findet nirgends eine Streckung des Materials statt. Ebenso wie beim Verfahren nach dem Hauptpatent ist auch bei diesem Herstellungsverfahren der Größe der Übergangsbogen an den Lappen d praktisch keine Grenze gesetzt.The -f piece shown consists of the passage piece a, the nozzle b and the two sheet metal pieces c. During production, an elongated hole is cut into the through piece a, on the edge of which the connecting piece b and the two sheet metal pieces c are to be welded and the length of which depends on the desired size of the arch on the tab d. The socket b (Fig. 3 and 4.) is cut open at four points in the longitudinal direction as far as the size or radius of the arch to be produced on the tab d requires. The two opposing tabs e running in the longitudinal direction of the through-connection are cut off from the resulting four tabs, so that two square openings are created. The four incisions can also be made in the nozzle b so that the resulting openings have any other shape, for. B. have an acute-angled. The two remaining flaps d are now bent in a die to the desired extent (Fig. 5). After the connector b, ie its two tabs d, has been welded onto the passage piece a, two openings remain free on the front and rear surfaces of the connector, into which sheet metal pieces c of the wall thickness of the tubes are welded. All wall thicknesses, including those of the tabs d, remain unchanged because there is no stretching of the material anywhere. As with the process according to the main patent, there is practically no limit to the size of the transition bend on the tabs d in this manufacturing process.
