Description
Beim Bohren und Gewindeschneiden von Sacklöchern werden durch das Werkzeug nicht alle entstehenden Späne aus der Bohrung hinausgefördert. Vielmehr müssen die Reste nach Beendigung der Bearbeitung durch Ausblasen oder Aussaugen entfernt werden. Häufig angewendet wird das Ausblasen mit dem Preßluftstrahl, das aber deshalb vielfach nicht befriedigt, wei!1 die Späne erfahrungsgemäß aus dem Preßluftwirbel wieder in die Bohrung zurückfallen. Sauggeräte leiden häufig an dem Mangel, daß die Saugwirkung . zu gering ist; die Späne also nicht restlos entfernt werden.When drilling and tapping blind holes, the Tool not all of the chips that are produced are conveyed out of the hole. Much more the residues must be blown or vacuumed after finishing the processing removed. Blowing out with the compressed air jet is often used but often not satisfied because of this, experience has shown that the chips come from the The vortex of compressed air falls back into the hole. Vacuum devices often suffer from this Lack that suction. is too low; the chips are not completely removed will.
Der Spanbläser gemäß der Erfindung ist gekennzeichnet durch eine vor oder in das Bohrloch eingeführte Druckluftdüse und einen rohrartigen Krümmer zum Abführen der ausgeblasenen Späne, der sich mit einem ebenen Rand auf die Fläche rings um das Bohrloch aufsetzen läßt. In einer besorideren Ausführungsform der Erfindung enthält der Aufsitzrand einen an die Druckluftleitung angeschlossenen Ringkanal, aus dem Druckluft durch wirbeldüsenartige Öffnungen in den Raum oberhalb des Bohrloches ausströmen kann. Versuche mit diesem Gerät haben seine einwandfreie Brauchbarkeit erwiesen.The chip blower according to the invention is characterized by a before or a compressed air nozzle inserted into the borehole and a tubular bend for Discharge of the blown chips, which have a flat edge on the surface can put on all around the borehole. In a particular embodiment of the invention the seat edge contains a ring channel connected to the compressed air line, from the compressed air through vortex-nozzle-like openings into the space above the borehole can flow out. Experiments with this device have its perfect usability proven.
Ein Ausführungsbeispiel des Gerätes ist in den Fig. i und 2 in einer Ansicht von unten und in einem Längsschnitt dargestellt. Das Gerät wird mit einem Stutzen i an eine nicht dargestelltePreßluftleitung angeschlossen. Die Luftzufuhr ist durch ein Ventil 2 abgesperrt, das durch eine Feder 3 angedrückt wird und mit Hilfe des Hebels q. geöffnet werden kann. Der Druckluftkanal 5 endet in einer Düse 6, die in das Bohrloch 7 eingeführt wird. Um die Düse herum ist ein Rand 8 gelegt, der gegenüber der Fläche 9 hinreichend abdichtet. io ist ein Krümmer, der sich nach der Mündung i i zu diffusorartig erweitert. Das Gerät wird in der dargestellten Weise aufgesetzt und der Hebel q. niedergedrückt. Es entsteht dann eine kräftige Luftströmung, die alle im Bohrloch befindlichen Späne nach außen befördert. Um zu vermeiden, daß sich etwa in toten Winkeln Späne sammeln, ist oberhalb der Fläche 8 ein Ringkanal 12 vorgesehen, der über Öffnungen 13 mit dem Raum 14. in Verbindung steht. Die Öffnungen 13 sind derart ausgebildet, daß sie wie Wirbeldüsen wirken. Sie erzeugen oberhalb des Bohrloches eine kräftige, kreisartige Strömung, die das Festsetzen von Spänen in dem Ringraum 15 verhindert.An embodiment of the device is shown in FIGS. I and 2 in a view from below and in a longitudinal section. The device is connected to a compressed air line (not shown) with a connector i. The air supply is blocked by a valve 2, which is pressed by a spring 3 and with the help of the lever q. can be opened. The compressed air channel 5 ends in a nozzle 6 which is introduced into the borehole 7. An edge 8 is placed around the nozzle which seals sufficiently with respect to the surface 9. io is a bend which widens to a diffuser-like manner after the mouth ii. The device is put on in the manner shown and the lever q. depressed. A strong air flow then arises, which transports all of the chips in the borehole to the outside. In order to prevent chips from collecting in blind spots, for example, an annular channel 12 is provided above the surface 8 and communicates with the space 14 via openings 13. The openings 13 are designed in such a way that they act like vortex nozzles. They generate a strong, circular flow above the borehole, which prevents chips from settling in the annular space 15.
