Description

Verfahren zur Herstellung der Ansc.hlußstutzen bei Sammeikammern Die Erfindung betrifft ein Verfahren zur Herstellung der Anschlußstutzen bei Sammelkammern, z. B. bei Überhitzerkammern. Bisher wurden die Stutzen für sich hergestellt und in die Kammerwand eingeschraubt und mit der Wand verschweißt. Die in dieser Weise angebrachven Stutzen wu den bei den heutzutage üblichen hohen Drücken und Temperaturen oft undicht. Es ist-~deshalb bereits vorgeschlagen worden, die Stutzen mittels eines an einem Zieheisen befestigten Stempels aus der Kammerwand herauszuziehen. Bei starkwandigen Rohren stößt eine derartige Herstellung jedoch auf Schwierigkeiten, die unter anderem darin bestehen, daß die Rammerwand leicht zu stark ausgebeult wird. Ein bekanntes Verfahren, bei welchem aus einem ebenen Boden Stutzen herausgedrückt werden, wobei der Boden an der Stelle des Stutzens zunächst bis auf e'ne verhältnismäßig dünne Restwand mit einer Bohrung versehen wird, kann bei Kammern nicht angewandt werden. Die Erfindung, welche die bestehenden Schwierigkeiten vermeidet, besteht darin. daß die Wand an der Stelle des Stutzens hinterdreht wird, bevor der Stutzen -mittels eines Ziebeisens herausgezogen wird.Process for the production of connection pieces in collecting chambers The invention relates to a method for producing the connecting pieces in collecting chambers, z. B. with superheater chambers. So far, the nozzles were made for themselves and screwed into the chamber wall and welded to the wall. That way Attached nozzles with the high pressures and temperatures that are common nowadays often leaking. It has therefore already been proposed to connect the nozzle by means of a to pull the punch attached to a drawing iron out of the chamber wall. With thick-walled Tubing, however, encounters difficulties in such a manufacture, among other things consist in the fact that the rammer wall is easily bulged too much. A well-known one Method in which nozzles are pushed out of a level floor, wherein the bottom at the point of the nozzle is initially relatively thin except for one The remaining wall is provided with a hole, cannot be used for chambers. The invention which avoids the existing difficulties consists in this. that the wall is turned back at the point of the nozzle before the nozzle -mittel a pulling iron is pulled out.

In der Zeichnung ist die Erfindung in einer Ausführungsform beispielsweise dargestellt. In the drawing, the invention is in one embodiment for example shown.

Abb. 1 zeigt den zum Ziehen vorbereiteten Teil einer Sammelkammer mit der Zieheinrichtung vor dem Ziehen des Anschlußstutzens.Fig. 1 shows the part of a collecting chamber prepared for pulling with the pulling device before pulling the connecting piece.

Abb. 2 zeigt dieselbe Kammer nach dem Ziehen des Stutzens.Fig. 2 shows the same chamber after pulling the nozzle.

Die Herstellung eines Stutzens erfolgt in folgender Weise: In die Wand n wird ein durchgehendes Lochs gebohrt. Konzentrisch mit diesem Loch wird die Wand bei r hinterdreht. Sodann wird durch das Loch das Zieheisen d hindurchgesteckt, welches am Ende mit einer einfachen und leicht lösbaren Vorrichtung zum Befestigen des Stempels versehen ist. Durch eine größere Öffnung der Kammerwand als die Bohrung 6, z. B. durch die Öffnung an der Stirnseite der Kammer, wird ein Stempel c in das Innere der -Ixammer eingebracht und mit dem Ende des Zieheisens d durch Verschrauben oder auch durch seitliches Ineinanderschieben verbunden. Das Herausziehen des Stempels erfolgt darin mittels einer Presse, nachdem die Umgebung des Loches b erhitzt worden ist. Die Kammerwand wird nach unten entsprechend abgestützt. The production of a nozzle is carried out in the following way: In the A through hole is drilled in wall n. The will be concentric with this hole Back-turned wall at r. Then the drawing die d is pushed through the hole, which at the end with a simple and easily detachable device for fastening of the stamp is provided. Through a larger opening in the chamber wall than the bore 6, e.g. B. through the opening at the front of the chamber, a stamp c is in the Inside the -Ixammer introduced and screwed to the end of the drawing iron d or connected by sliding one into the other. Pulling out the stamp is carried out therein by means of a press after the vicinity of the hole b has been heated is. The chamber wall is supported accordingly at the bottom.

Es entsteht auf diese Weise ein Anschlußstutzen, wie er in Abb. 2 dart,estellt ist. Nach dem Ziehen der Anschlußstutzenwird die Öffnung an der Stirnseite der Kammer durch Kümpeln verschlossen und mittels eines eingeschraubten Stopfens, der mit der Wand nach dem Einschrauben zusätzlich verschweißt wird, dichtgesetzt. Die Hinterdrehung c wird zweckmäßig so ausgeführt, daß man nacll dem Ziehen einen Stutzen von der gleichen oder annähernd gleichen Wandstärke erhält, wie - sie das anzuscblleßrnde Rohr besitzt.In this way, a connection piece is created, as shown in Fig. 2 dart, is established. After pulling the connecting piece, the opening is on the front side the chamber is closed by pumping and by means of a screwed-in stopper, which is additionally welded to the wall after it has been screwed in. The undercut c is expediently carried out in such a way that, after pulling, a Nozzles of the same or approximately the same wall thickness as - they receive that Has a tube to be closed.
