Description

Lntopän- und Kühlvorrichtung an Bohrmaschinen Zur raschen Abfuhr des Bohrmehls und zur Kühlung des Bohrers ist es bekannt, einen Drucklufts.trahl in der Bohrrichtung auf das Bohrloch zu richten oder ein Kühlnittel durch einen hohlen Bohrer in das Bohrloch zu drücken. Es hat sich jedoch gezeigt, daß das Anblasen des Bohrers und das nach dem Herausziehen des Bohrers aus dem Bohrloch erfolgende Durchblasen des Bohrloches durch einen aus einer in einigem Abstand vom Bohrloch angebrachten Druckluftdüse strömenden Euftstrahl nicht ausreichend ist, das Bohrloch in jedem Fall von Bohrmehl zu reinigen. Während des Bohrvorganges behindert au2erden der Druckluftstrahl die Entspanung, da der Druckluft strahl der Entspanung srichtung entgegengesetzt gerichtet ist. Eine Kühlmittelzufuhr durch einen hohlen Bohrer ist bei Bohrern mit kleinen Durchmessern nicht zu verwirklichen. Die Erfindung vermeidet-diese Nachteile dadurch, daß erfindung sgemäß in Gegenhalter oder Niederhalter der Bohrmaschine ein Kanal verläuft, der an einem Drukluftanschluß beginnt und der beim -chnit.tpunkt der gedachten Bohrerachse mit der OberflC'-:che des Gegenhalters oder '-iiederhalters Mündet, so daß beim Eur chtritt und anschlic2enden Zurückziehen des Bohrers an die 'Stelle des Bohrerdur chtr ittes Druckluft bla sbar ist. Der beim Bohrerdurchtritt erfolgende Druckluftstoß entlang ^ der Bohrerdrallnut beseitigt alle Ansätze zur Zuetzung.der Drallnut mit Bohrmehl, entfernt beim Zierausziehen. des Bohrers Bohrmehlan--@itze an der Bohrung wand und kühlt den Bohrer zur Vermeidung von Verklebungen entlang der Bohrerdrallnut. Bei einer fühlerstiftgeoteuerten Kopierbohrmaschine, bei der Bohrer und gegenhaltender Fühlerstift in einer Achse liegen, wird in vorteilhafter -;`eise eine mit durchgehenden Bohrungen ver2ehene Schablone verwendet und durch einen Kanal im Fühlerstift Druclzluft an die Stelle des Bohrerdurchtritts geblasen. Zur Wirk sanen Unterstützung der Entspan- und Kühlwirkung der V cr richtung hat es sich als vorteilhaft erwiesen, den Bohrkopf mit einen nahezu geschlossenen Gehäuse zu umgeben, das in die i;urchtrittsüffnung für den Bohrer mündende ZulüftkanC:;le und Absaugel:ünäle besitzt. Hierdurch können schon vor den Bohrerdurchtrit t in den den Bohrkopf umgebenden Gehäuse Strümung:verhältni; le erzeugt werden, die den beim Bohrerdurchtritt entstehenden üruckluftstoß wirksam unterstützen. Ausführungsbeispiele der Vorrichtung nach der yrfindung sind in den Zeichnungen dargestellt. %o zeig t , F igar 1 eine Druckluftzufuhr durch den Gegenhalter und _'-igur 2 3ine ruckluftzufuhr durch einen y ühlerstft . In den Gegenhalter bzw. der Auflage 1 in der Figur 1 verläuft der Kanal 2, der mit den Druckluftanochluß 3 in Verbindung steht'ünd an der Stelle des.Durchtritts des Bohrers 4 durch den :lattensta'pel -.5 an die OberflLche der Auflage 1 mündet.Lntopän- and cooling device on drilling machines For the rapid removal of the drilling dust and for cooling the drill, it is known to direct a compressed air jet in the drilling direction onto the borehole or to press a cooling agent through a hollow drill into the borehole. However, it has been shown that blowing the drill bit and then blowing the drill hole through it after it has been pulled out of the borehole by an air jet from a compressed air nozzle at some distance from the borehole is not sufficient to close the borehole with drill dust in any case clean. During the drilling process, the compressed air jet also hinders the stress relief, since the compressed air jet is directed in the opposite direction to the stress relief. It is not possible to supply coolant through a hollow drill with drills with small diameters. The invention avoids these disadvantages in that, according to the invention, a channel runs in the counterholder or downholder of the drilling machine, which begins at a pressure air connection and which opens at the cutting point of the imaginary drill axis with the surface of the counterholder or downholder so that compressed air can be blown when stepping in and then withdrawing the drill at the point of the drill hole. The blast of compressed air that occurs along the drill twist groove when the drill passes through removes all approaches to clogging the twist groove with drilling dust, removed during the ornamental extraction. of the drill bit drills on the hole wall and cools the drill bit to avoid sticking along the drill bit flute. In the case of a feeler-pen-controlled copy drilling machine, in which the drill and the counter-holding feeler pin lie in one axis, it is advantageous to use a template with through-holes and to blow compressed air through a channel in the feeler pin at the point where the drill can pass. In order to effectively support the stress relief and cooling effect of the V cr direction, it has proven to be advantageous to surround the drill head with an almost closed housing that has supply ducts and suction ducts opening into the opening for the drill. As a result, before the drill penetrates into the housing surrounding the drill head, flow: ratio; oils can be generated that effectively support the blast of return air that occurs when the drill passes through. Embodiments of the device according to the invention are shown in the drawings. % o shows, Fig. 1 shows a compressed air supply through the counterholder and _'- igur 2 3 a return air supply through a cooler. The channel 2, which is connected to the compressed air connection 3, runs in the counterholder or the support 1 in FIG 1 opens.

er Bohrkopf 6 befindet sich. in :den..Gehäuse 7, das in die Bohrerdurchtritt öffnung mündende. Zuluftkanäle B und Absauge-9 besitzt. Ein weiteres Ausführungsbeispiel der Entspan- und Kühlvorrichtung zeigt Figur 2 bei einer Kopierbohrmaschine, deren Fühlerstift und Bohrer in einer Achse liegen. In dem Fühlerstift 10 befindet sich der Kanal 11, der Anschluß,an eine Druckluftzufuhr bei 12 hat. Der Fühlerstift 10 wird nach dem Hineinfallen in die Senkung der Schablone 13 durch einen nicht dargestellten Druckluftkolben in die Senkung gedrückt. Diese Bewegung wird dazu benutzt den Bohrervorschub in Gang zu setzen. Leim iurchtritt des Bohrers 4 durch den Plattenstapel 5 strömt Druckluft aus dem Fühlerstift 10 durch die mit durchgehenden Dohrungen versehene Schablone 13 zum Bohrloch im Plattenstapel 5. Auch bei diesem Ausführungsbeispiel befindet sich der Bohrkopf Ei in einem nahezu geschlossenen Gehäuse 7 . das in der oben geschilderten Weise die Entspan- und Kühlwirkung vorteilhaft unterstützt. Eine intensivere Kühlung des Bohrers und eine verbesserte Bohrmehlabfuhr kann durch ein dampfförmiges oder flüssiges Mittel erreicht werden, das anstelle der Druckluft durch die Bohrung strömt.he drill head 6 is located. in: the .. housing 7, which passes into the drill bit opening mouth. Has supply air ducts B and suction-9. Another one Embodiment of the stress relief and cooling device is shown in FIG. 2 in a copy drilling machine, whose feeler pin and drill are in one axis. Located in the feeler pin 10 the channel 11, the connection, has a compressed air supply at 12. The feeler pen 10 is not after falling into the depression of the template 13 by one compressed air piston shown pressed into the depression. This movement becomes that used to start the drill feed. Glue penetration of the drill 4 through the stack of plates 5, compressed air flows from the feeler pin 10 through the continuous Drilled template 13 for the borehole in the stack of plates 5. Also with this one Embodiment is the drill head Ei in an almost closed Housing 7. which in the manner described above, the relaxation and cooling effect is advantageous supports. More intensive cooling of the drill and improved removal of drill dust can be achieved by a vapor or liquid means that instead the compressed air flows through the bore.
