Description
Vorrichtung zur Herstellung von Stutzen aus der vollen Wandung von Hohlkörpern. Die Erfindung betrifft eine Vorrichtung zur Herstellung von Stutzen aus der vollen Wandung von Hohlkörpern mit Hilfe von Stempel und Kugeln.Device for the production of nozzles from the full wall of Hollow bodies. The invention relates to a device for producing nozzles from the full wall of hollow bodies with the help of punches and balls.
Sie besteht darin, daB zur Aufnahme und Führung der Kugeln ein in den Hohlkörper eingesetztes, mit einem Kanal versehenes Kernstück dient, der entsprechend der Lage der Stutzenachse zur Achse des ursprünglichen Hohlkörpers verläuft. Gegenüber bekannten Einrichtungen, die ein Kernstück zur Aufnahme der Kugeln nicht besitzen, weist der Gegenstand der Erfindung den Vorteil auf, daß gleichzeitig mehrere Kugeln von geringen Abweichungen im Durchmesser Anwendung finden können, so daß bei einem einzigen Vorgang des Stempels ein allmähliches Auspressen des Stutzens in die gewünschte Form bewirkt werden kann.It consists in the fact that an in the hollow body inserted, provided with a channel core piece is used, which accordingly the position of the nozzle axis to the axis of the original hollow body. Opposite to known Devices that have a core for receiving the balls do not have, the object of the invention has the advantage that at the same time several balls with small deviations in diameter can be used, so that with a single operation of the punch a gradual pressing out of the connecting piece can be effected in the desired shape.
Auf den Zeichnungen ist der Gegenstand der Erfindung beispielsweise veranschaulicht. Abb. z zeigt einen Längsschnitt, und Abb. z stellt eine Aufsicht der Preßvorrichtung dar.In the drawings, the subject matter of the invention is for example illustrated. Fig. Z shows a longitudinal section and Fig. Z shows a top view the pressing device.
Das Rohr a wird in ein im vorliegenden Falle aus zwei Backen b und c bestehendes Futter gebracht, das durch einen Preßtopf d zusammengehalten wird. In das Rohr a wird das Kernstück g eingeschoben, dessen innere Bohrung m dem lichten Durchmesser des herzustellenden Stutzens entspricht. Die zunächst senkrechte Bohrungsachse geht in eine wagerechte Lage über bis zur Wandung ;des Rohres a. Der Kanal m im Kernstück g wird mit Kugeln f gefüllt, auf welche der Preßstempel h in Pfeilrichtung i wirkt. Mittels des Preßstempels h wird durch die Kugeln t die außer in der Öffnung e des Preßtopfes allseitig eingespannte Rohrwandung ausgebeult und zum Rohrstutzen n ausgepreßt. Zur Erleichterung des Pressens und zur Vermeidung eines Reißens der Wandung wird das Rohr n vorher in der Mitte des anzupressenden Stutzens mit einem kleinen Loch versehen. Die freiliegende, auszupressende Wandung wird durch eine Stichflamme k durch das Loch s in der Pfeilrichtung l angewärmt. Nacherfolgter Pressung wird das Kernstückg aus dem Rohre a entfernt; das Rohr a samt den Backen b und c -wird dann aus dem Preßtopfe d herausgehoben, und die Backen b und c werden vom gepreßten Rohre abgenommen. Die Stutzen können in beliebiger Anzahl und Stellung angepreßt werden. Je nach Gestaltung und Anzahl der Stutzen ist das Futter b und c in entsprechende Backen zu verlegen.The tube a is placed in a chuck consisting in the present case of two jaws b and c, which is held together by a press pot d. The core piece g is pushed into the tube a, the inner bore m of which corresponds to the clear diameter of the connecting piece to be produced. The initially vertical axis of the bore changes into a horizontal position up to the wall; of the pipe a. The channel m in the core g is filled with balls f on which the ram h acts in the direction of the arrow i. By means of the ram h, the pipe wall, which is clamped on all sides except in the opening e of the press pot, is bulged by the balls t and pressed out to the pipe socket n. To make pressing easier and to avoid tearing the wall, the pipe n is previously provided with a small hole in the center of the nozzle to be pressed. The exposed wall to be pressed out is heated by a jet flame k through the hole s in the direction of the arrow l. After pressing, the core piece is removed from the tube a; the tube a together with the jaws b and c - is then lifted out of the press pot d , and the jaws b and c are removed from the pressed tube. The nozzles can be pressed on in any number and position. Depending on the design and number of nozzles, chucks b and c are to be placed in corresponding jaws.
