Reimar Pohlman 51 Aachen» den 21.4.1972Reimar Pohlman 51 Aachen »April 21, 1972 Manfred CichosManfred Cichos Verfahren zur Einleitung von SprödbrüchenProcedure for initiating brittle fractures

Es ist bekannt, mit Hilfe von Ultraschallschwingungen harte und spröde Materialien zu bearbeiten. Hierbei wird ein beliebig profiliertes zu Längsschwingungen erregtes Werkzeug unter Zwischengabe einer Borkarbidsuspension in das zu bearbeitende Material eingesenkt. Auf diesem Wege lassen sich Durchbrüche, Gesenke usw. in harte und spröde Materialien einbringen.It is known to use hard ultrasonic vibrations and to work on brittle materials. A tool with any profile is excited to produce longitudinal vibrations sunk into the material to be processed with the addition of a boron carbide suspension. In this way you can Making breakthroughs, dies, etc. in hard and brittle materials.

Das vorliegende Verfahren verfolgt einen ganz anderen Zweck, nämlich in harten und spröden Körpern Sprödbrliche zu erzielen, die fraglichen Körper zu zertrümmern, ,in StUcke zu zersprengen oder gegebenenfalls in einer vorgegebenen Linienführung zu trennen. Als Beispiel für den erstgenannten Vorgang sei die Zertrümmerung von Harnsteinen genannt. Der in der menschlichen Blase befindliche Harnstein soll hierbei so weit zertrümmert bzw. zerkleinert werden, daß die Trümmer mühelos abgesaugt oder auf natürlichem Wege aus der Blase entfernt werden können. Für den zweiten Vorgang sei als Beispiel das Glasschneiden genannt. Hier kommt es darauf an, die in einem vorgegebenen Linienzug angeritzte Glasscheibe durch einen Sprödbruch entlang der vorgezeichneten Linienführung zu trennen.The present process pursues a completely different purpose, namely to achieve brittle bodies in hard and brittle bodies, to smash the bodies in question, to shatter them into pieces or, if necessary, to separate them in a given line. As an example of the first-mentioned process is the Called the crushing of urinary stones. The urinary stone in the human bladder is said to be smashed so far or crushed so that the debris can be easily aspirated or removed naturally from the bladder. For the second process, glass cutting is an example called. Here it is important to move the glass pane, which has been scratched in a given line, through a brittle fracture to separate the pre-drawn lines.

Versucht man mit Hilfe von Ultraschallschwingungen Sprödbrüche durchzuführen, so lassen sich beispielsweise bei der Harnsteinzertrümmerung relativ weiche Steinarten wie Phosphatsteine mehr oder weniger schnell durch Ultraschallschwingungen abbauen. Härtere Sorten hingegen wie Uratsteine, Oxalatsteine lassen sich nur außerordentlich langsam oder überhaupt nicht in kleinere Trümmer zerlegen. Beim Glasschneiden gelingt es beispielsweise nicht, in dickeren Scheiben - und nur diese sind technisch interessant - durch Berührung mit einem Ultraschallübertrager den Bruchvorgang auszulösen.If you try brittle fractures with the help of ultrasonic vibrations For example, relatively soft types of stone such as phosphate stones can be used when crushing urinary stones degrade more or less quickly through ultrasonic vibrations. Harder types, on the other hand, such as urate stones and oxalate stones, can only be broken into smaller ones extremely slowly or not at all Break up rubble. When cutting glass, for example, it does not work in thicker slices - and only these are technically interesting - by touching an ultrasonic transducer trigger the breaking process.

Untersuchungen haben nun gezeigt, daß es möglich ist, Sprödbrüche dadurch einzuleiten, daß ein stab- oder rohrförmiger Ultraschallschwinger unter Zwischenschaltung eines Prallkörpers den zu brechenden Körper berührt. Die zersprengende Wirkung der Ultraschallschwingungen wird dadurch um Größenordnungen gesteigert, daß zwischen den eigentlichen Ultraschallschwinger, beispielsweise ein Mason-Horn, und den zu brechenden Körper ein Prallkörper zwischengeschaltet wird, der jede beliebige Form besitzen kann. Er soll möglichst hart und unnachgiebig sowie locker zwischen dem Ultraschallschwinger und dem zu brechenden Körper angeordnet sein. Dieser hochelastische Körper ist in der Lage, aus den periodisch auf ihn'einwirkenden Ultraschallschwingungen statistisch Impulsstöße zu "sammeln" und diese in sehr kurzen und höchst intensiven Schlagstößen auf den zu brechenden Körper zu übertragen. Es hat sich gezeigt, daß diese gesammelten hochintensiven Impulsstöße Größenordnungen erreichen und Schlagkräfte auszulösen vermögen, welche die vom Ultraschallübertrager periodisch übertragenen Druckspitzen um ein Vielfaches über steigen und in der Lage sind, die gewünschten Sprödbrüche auszulösen. Auch die härtesten Harnsteinsorten (Urat- und Oxalatsteine) können hiermit abgebaut, angeritzte Glasscheiben bis zu 25 mm Dicke mit einer derartigen Anordnung getrennt werden.Investigations have now shown that it is possible to have brittle fractures initiate that a rod-shaped or tubular ultrasonic transducer with the interposition of an impact body touches the body to be broken. The shattering effect of the ultrasonic vibrations is thereby by orders of magnitude increased that between the actual ultrasonic transducer, for example a Mason horn, and that too breaking body an impact body is interposed, which can have any shape. He should if possible be arranged hard and unyielding as well as loosely between the ultrasonic transducer and the body to be broken. This highly elastic body is able to move out periodically ultrasonic vibrations acting on it statistically To "collect" impulses and to transfer them to the body to be broken in very short and extremely intense blows. It has been shown that these collected high-intensity impulses reach orders of magnitude and impact forces able to trigger, which the pressure peaks periodically transmitted by the ultrasonic transmitter by a multiple rise and are able to trigger the desired brittle fractures. Even the hardest types of urinary stone (urate and Oxalate stones) can be dismantled with this, scratched glass panes up to 25 mm thick can be separated with such an arrangement will.

Die Figuren zeigen beispielsweise Vorrichtungen zur Durchführung des erfindungsgemäßen Verfahrens:The figures show, for example, devices for carrying out the method according to the invention:

Figur 1 zeigt den Arbeitsteil einer Rohrsonde zur Zertrümmerung von Harnsteinen.Figure 1 shows the working part of a tube probe for breaking up urinary stones.

In Fig. 1 stellt 1 das mit Ultraschall zu Längsschwingungen angeregte Rohr dar. Die Schwingungsrichtung ist durch Doppelpfeil gekennzeichnet. Mit 2 ist der Prallkörper bezeichnet,In Fig. 1, 1 represents the ultrasound to longitudinal vibrations excited tube. The direction of oscillation is indicated by a double arrow. With 2 the impact body is referred to,

3098A4/0720 -3098A4 / 0720 -

der hier beispielsweise als Rohr ausgebildet ist und an seinem Arbeitsende eine Verzahnung 7 trägt. Durch die Längsschwingungen des Rohres 1 werden Impulse auf den Prallkörper 2 übertragen, die sich in der oben beschriebenen Weise zu sehr hohen Impulsspitzen aufsteige™ wenn der Prallkörper 2 locker in dem Rohr 1 gehaltert ist. Die wesentliche Prallfläche befindet sich an der Stelle 3. Die lockere Halterung ist dadurch gewährleistet, daß eine hinreichende Toleranz in der Schaftführung 4 vorgesehen ist und das Herausfallen des Prallkörper 2 aus dem Rohr 1 beispielsweise durch einen lockeren Sprengring 5, der in einen Schlitz 6 des Prallkörpers 2 eingreift, verhindert wird. Die Zähne 7 des als Rohrstück ausgebildeten Prallkörpers 2 sind verschränkt angeordnet, damit nur Trümmer in das Rohr 1 eindringen können, deren Durchmesser kleiner als derjenige des Rohres ist, so daß ein müheloses Absaugen.der Trümmer durch " Rohr 1 hindurch möglich wird. Die Zähne 7 sind zweckmäßiger- v weise trapezförmig, mit ihrer breiten Seite zur Stirnseite. ... hin gerichtet, ausgebildet, damit sie sich bei einem weniger spröden Material nicht festfressen sondern selbstätig frei bohren können.which is designed here as a tube, for example, and has a toothing 7 at its working end. The longitudinal vibrations of the pipe 1 transmit impulses to the impact body 2, which rise to very high impulse peaks in the manner described above when the impact body 2 is loosely held in the pipe 1. The main impact surface is located at point 3. The loose mounting is ensured by the fact that sufficient tolerance is provided in the shaft guide 4 and that the impact body 2 can fall out of the tube 1, for example by a loose snap ring 5, which is inserted into a slot 6 of the Impact body 2 engages, is prevented. The teeth 7 of the baffle 2, designed as a pipe section, are arranged crossed, so that only debris can penetrate into the pipe 1, the diameter of which is smaller than that of the pipe, so that an effortless Absaugen.der debris through "pipe 1 is possible. The teeth 7 are expediently v as trapezoidal, formed with its broad side to the front side. ... directed toward so they can not seize up in a less brittle material but selbstätig drill free.

Die beschriebene Ausführung stellt lediglich ein Beispiel einer Vorrichtung zur Durchführung des Verfahrens dar.The embodiment described represents only one example of a device for carrying out the method.

Fig. 2 zeigt ein Vorrichtungsbeispiel zur.Trennung einer Glasscheibe. Ein stabförmiger, in Richtung des Doppelpfeiles schwingender Ultraschallschwinger 1' trägt an seinem Arbeitsende den als Kugel ausgebildeten Prallkörper 21. Die Prallfläche ist mit 3' bezeichnet. Das Herausfallen der Kugel wird wiederum durch einen in den Stab 1' eingelassenen Sprengring 51 verhindert. Die Anordnung berührt die an der Stelle 91 angeritzte Glasscheibe 8'. Durch die beschriebene Impulsakkumulierung werden so kräftige und zahlreiche Stöße gegen die Glasscheibe gerichtet, daß der gewünschte Sprödbruch entlang der Reißlinie 91 erfolgt.Fig. 2 shows an example of a device for separating a pane of glass. A rod-shaped ultrasonic oscillator 1 ', oscillating in the direction of the double arrow, carries at its working end the impact body 2 1 designed as a ball. The baffle is denoted by 3 '. The falling out of the ball is in turn prevented by a snap ring 5 1 embedded in the rod 1 '. The arrangement touches the glass pane 8 'scored at point 9 1. As a result of the impulse accumulation described, such strong and numerous impacts are directed against the glass pane that the desired brittle fracture occurs along the tear line 9 1 .
