Description

Den Gegenstand vorliegender Erfindung bildet ein Gewindeschneidzeiug mit Gewindeschneideisen von kegeligem Umfang, das ■durch achsiale Verschiebung in einer kegeligen Ausdrehung seines Haltergehäuses eingestellt wird. Nach der Erfindung wird das Schneideisen zwischen einem auf den Halter aufgeschraubten Überwurfring und einen in den Halter eingeschraubten to Bolzen eingestellt und festgeklemmt. Da sich die Einstellorgane beiderseitig gegen die Flachseiten des Schneideisens legen, so kann dieses seine Lage in achsialer Richtung zum Halter nicht ändern.The subject of the present invention is a thread cutting tool with a thread cutting tool of conical circumference, which ■ by axial displacement in a conical recess of its holder housing is set. According to the invention, the die is between a union ring screwed onto the holder and a bolt screwed into the holder is set and clamped. There the adjusting elements lie on both sides against the flat sides of the die, so can this does not change its position in the axial direction to the holder.
In der Zeichnung ist die Erfindung dargestellt. The invention is shown in the drawing.

Das Gehäuse des Schneideisenhalters e hat eine kegelige Ausdrehung. Von oben wird es durch einen aufgeschraubten Überwurfring b geschlossen, und vom Boden aus ist ein hohler Bolzen c eingeschraubt. Überwurfring b und Bolzen c sind am Umfang gerändelt oder sechskantig, um sie mit der Hand oder mit Schlüssel drehen zu können. Das Schneideisen hat eine runde Form (Abb. 2) und ist geschlitzt, so daß es sich federnd zusammendrücken läßt. Das Schneideisen kann aber ; auch in mehrere Stücke geteilt sein (Abb. 3), welche durch geeignete Federn in Stellung : gehalten werden. Der Umfang §· des Schneideisens ist kegelig und der Ausdrehung des Gehäuses e angepaßt.The housing of the die holder e has a conical recess. It is closed from above by a screwed-on union ring b , and a hollow bolt c is screwed in from the bottom. Coupling ring b and bolt c are knurled or hexagonal on the circumference so that they can be turned by hand or with a key. The cutting die has a round shape (Fig. 2) and is slotted so that it can be pressed together resiliently. But the die can; also be divided into several pieces (Fig. 3), which are held in position by suitable springs. The circumference § · of the die is conical and adapted to the recess of the housing e.
Das Schneideisen wird in das Gehäuse e eingelegt, und zwar ist es im Umfang so groß, daß es bei Berührung der kegeligen Ausdrehung α noch etwas über den Gehäuserand d vorsteht. Durch Aufschrauben des Überwurfringes b und Einschrauben des Bolzens c wird das Schneideisen zwischen beide eingestellt und festgeklemmt. Durch Lösen des Bolzens und Nachziehen des Überwurfringes wird das Schneideisen in die kegelige Ausdrehung α des Halters achsial eingepreßt. Durch umgekehrtes Verfahren wird es aus dem Halter herausgeschoben. Durch Federkraft kann es sich dabei auseinanderspreizen. Dadurch kann Gewinde von verschieden großen Durchmessern geschnitten werden. Damit sich das Schneideisen beim Gebrauch nicht drehen kann, sind am Umfang desselben Nuten / eingeschnitten und im Gehäuse entsprechende Keile oder Federn angebracht.The cutting die is inserted into the housing e , and its circumference is so large that it protrudes slightly beyond the edge d of the housing when it touches the conical recess α. By screwing on the union ring b and screwing in the bolt c , the die is set between the two and clamped. By loosening the bolt and tightening the union ring, the die is pressed axially into the tapered recess α of the holder. In the reverse process, it is pushed out of the holder. It can spread apart through spring force. This allows threads of different sizes to be cut. So that the die cannot rotate during use, grooves / are notched on the circumference of the die and corresponding wedges or springs are attached in the housing.
