Description

Kunststoffring zum lösbaren Festlegen eines Rundschaftmeißels in einer MeißelbüchsePlastic ring for releasably securing a round shank chisel in a chisel
Die Erfindung betrifft einen Kunststoffring zum lösbaren Festlegen eines Rundschaftmeißels in einer Meißelbüchse, bei welcher die Innenseite der Meißelbüchse eine Ringnut aufweist, in welche der in einer Ringnut des Meißelschafts aufgenommene federnde Kunststoffring eingreift, wobei der Kunststoffring geschlitzt ausgebildet ist und mindestens eine über die Außenfläche des Kunststoffringes vorspringende und sich über zumindest einen Teil des Umfangs des Kunststoffringes erstreckende Rippe aufweist.The invention relates to a plastic ring for releasably securing a round shank chisel in a chisel, wherein the inside of the chisel has an annular groove, in which engages the received in an annular groove of the chisel shank resilient plastic ring, wherein the plastic ring is formed slotted and at least one on the outer surface of the Plastic ring projecting and extending over at least part of the circumference of the plastic ring rib has.
Rundschaftmeißel werden an Schremmköpfen bzw. Schremmwalzen lösbar befestigt, sodass sie nach Abnützung mit möglichst geringem Arbeitsaufwand ersetzt werden können. Im Gegensatz zu der Forderung der leichten Lösbarkeit steht die Forderung eines guten Halts der Rundschaftmeißel an den Schremmköpfen bzw. Schremmwalzen, zumal sie relativ hohen Zentrifugalkräften und Querkräften ausgesetzt sind. Eine weitere Anforderung an die Befestigung eines Rundschaftmeißels an einer Meißelbüchse besteht darin, gegen die harten Betriebsbedingungen, verschärft durch Feinpartikel und Kühlflüssigkeit etc., unempfindlich zu sein. Diese Betriebsbedingungen sollen zudem auch das Lösen eines Rundschaftmeißels aus seiner Meißelbüchse nicht erschweren.Round shank bits are detachably fastened to clamping heads or clamping rollers so that they can be replaced after wear and tear with as little work as possible. In contrast to the requirement of easy solubility is the requirement of a good stop of the round shank chisel on the Schremmköpfen or Schremmwalzen, especially since they are exposed to relatively high centrifugal forces and shear forces. Another requirement for attaching a pick shank to a chisel is to be insensitive to harsh operating conditions exacerbated by fine particles and coolant, etc. These operating conditions should also not make it difficult to loosen a round shank chisel from his chisel.
Ein Kunststoffring zum lösbaren Festlegen eines Rundschaftmeißels in einer Meißelbüchse der eingangs beschriebenen Art ist aus der AT 004 193 Ul bekannt. Gemäß diesem Dokument gelingt das Einführen des Rundschaftmeißels in die Meißelbüchse dadurch, dass die Tiefe der Ringnut des Meißelschaftes die Gesamtdicke des Kunststoffringes im Bereich seiner Rippe übersteigt und der Schlitz eine derartige Breite aufweist, dass der Kunststoffring für die Montage im Durchmesser derart verkleinerbar ist, dass der Kunststoffring beim Einsetzen des Rundschaftmeißels in die Meißelbüchse nicht über den Durchmesser des Meißelschaftes im Bereich der Ringnut vorschaut. Beim Einbau eines Rundschaftmeißels wird der Kunststoffring so weit im Durchmesser verkleinert, dass er zur Gänze in der Ringnut des Rundschaftmeißels Platz findet, wodurch seine Rippe das Einsetzen des Rundschaftmeißels nicht behindern kann.A plastic ring for releasably securing a round shank chisel in a chisel of the type described above is known from AT 004 193 Ul. According to this document, the insertion of the round shank chisel in the chisel by the fact that the depth of the annular groove of the chisel shank exceeds the total thickness of the plastic ring in the region of its rib and the slot has a width such that the plastic ring for mounting in the diameter is so reduced that When inserting the round shank chisel into the chisel bush, the plastic ring does not look beyond the diameter of the chisel shank in the area of the annular groove. When installing a round shank chisel of the plastic ring is so far reduced in diameter that it fits completely into the annular groove of the round shank chisel, whereby his rib can not hinder the onset of the round shank chisel.
Erst wenn der Rundschaftmeißel in der Meißelbüchse den richtigen Sitz erreicht hat, federt der Kunststoffring auf und die Rippe des Kunststoffringes greift zumindest teilweise in die am Innenmantel der Meißelbüchse vorgesehene Ringnut ein. Somit ist gemäß dem Stand der Technik die Haltekraft durch das Auffedem des Kunststoffringes von einem Außendurchmesser kleiner bzw. gleich dem Außendurchmesser des Rundschaftmeißels auf einen diesen Außendurchmesser übersteigenden Durchmesser gegeben. Es hat sich gezeigt, dass im rauhen Schremmbetrieb die so hervorgerufene Haltekraß: oftmals nicht ausreicht. Es kommt infolge der Fliehkräfte 2x1 einem unfreiwilligen Entfernen eines Rundschaftmeißels aus der Meißelbüchse, was durch Schrägwände der Rippe und der hierzu korrespondierend ausgebildeten Ringnut begünstigt wird.Only when the round shank chisel has reached the correct seat in the chisel, the plastic ring springs on and the rib of the plastic ring engages at least partially in the provided on the inner surface of the chisel ring groove. Thus, according to the prior art, the holding force is given by the Auffedem of the plastic ring of an outer diameter smaller than or equal to the outer diameter of the round shank chisel on a diameter exceeding this outer diameter. It has been shown that in harsh Schremsmbetrieb the so-called Haltekraß: often insufficient. It comes as a result of centrifugal forces 2x1 involuntary removal of a round shank chisel from the chisel, which is favored by inclined walls of the rib and the corresponding purpose designed annular groove.
Die Erfindung stellt sich die Aufgabe, einen Kunststoffring der eingangs beschriebenen Art zu schaffen, mit dem ein einfaches Einsetzen eines Rundschaftmeißels in die Meißelbüchse und auch ein einfaches Entfernen ermöglicht ist, jedoch ein hinreichend fester Sitz des Rundschaftmeißels während des Betriebs in der Meißelbüchse gegeben ist. Die Aufgabe besteht also darin, zwei gänzlich gegensätzliche Anforderungen zu erfüllen.The invention has as its object to provide a plastic ring of the type described above, with a simple insertion of a round shank chisel in the chisel and also a simple removal is possible, however, a sufficiently tight fit of the round shank chisel is given during operation in the chisel. So the task is to fulfill two completely contradictory requirements.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Querschnitt des Kunststoffringes einen in radialer Richtung nach innen drückbaren und nach außen federnden Abschnitt, der sich zumindest über einen Teil des Umfangs des Kunststoffringes erstreckt, aufweist, wobei dieser Abschnitt gegenüber den anderen Abschnitten des Querschnitts des Kunststoffringes aus einer entspannten Ausgangslage mit einem bestimmten Außendurchmesser größer als der Innendurchmesser der Meißelbüchse in eine einen kleineren Außendurchmesser, der dem Innendurchmesser der Meiselbüchse entspricht, aufweisende Einbaulage drückbar ist und retour in die entspannte Ausgangslage federn kann, wobei entweder die Gesamtdicke des entspannten Kunststoffringes die Tiefe der Ringnut des Meißelschaftes übersteigt oder der Schlitz eine Breite aufweist, die derart bemessen ist, dass bei einer Reduktion des Durchmessers des Kunststoffringes bis zum Kontakt der Seitenwände des Schlitzes der radial federnde Abschnitt des Querschnitts des Kunststoffringes bei in die Ringnut eingesetztem Kunststoffring über den Außendurchmesser des Meißelschaftes vorragt.This object is achieved in that the cross section of the plastic ring has a radially inwardly compressible and outwardly resilient portion which extends at least over part of the circumference of the plastic ring, which portion relative to the other portions of the cross section of the plastic ring From a relaxed starting position with a certain outer diameter larger than the inner diameter of the chisel in a smaller outer diameter corresponding to the inner diameter of the Meiselbüchse, mounting position can be pressed and spring back into the relaxed starting position, either the total thickness of the relaxed plastic ring the depth of Ring groove of the drill collar exceeds or the slot has a width which is dimensioned such that in a reduction of the diameter of the plastic ring to the contact of the side walls of the slot of the radially resilient Ab section of the cross section of the plastic ring protrudes beyond the outer diameter of the drill collar when inserted into the annular groove plastic ring.
Die Grundidee der Erfindung liegt somit darin, dass das Eindringen des Kunststoffringes, d.h. seiner sich über zumindest einen Teil des Umfangs erstreckenden Rippe, in die Nut der Meißelbüchse nicht durch ein radiales Auffedern des gesamten Kunststoffringes erfolgt, sondern dadurch, dass die Rippe selbst federnd ausgebildet ist und radial über den Außenumfang des Kunststoffringes vorfedert. Dies kann prinzipiell auf zwei Arten erfolgen. Zum einen, dass die Gesamtdicke des Kunststoffringes dicker ist als die Tiefe der Ringnut des Meißelschaftes, oder dadurch, dass der Kunststoffring selbst dann, wenn sein Schlitz zusammengepresst ist, zumindest mit seiner Rippe noch über den Außendurchmesser des Meißelschaftes vorragt. Gemäß einer ersten bevorzugten Ausfuhrungsform ist der Querschnitt des Kunststoffringes wellenförmig gestaltet, wobei ein radial nach außen ragender Wellenberg den in radialer Richtung nach innen drückbaren und nach außen federnden Abschnitt des Querschnitts des Kunststoffringes bildet.The basic idea of the invention thus lies in the fact that the penetration of the plastic ring, ie of its rib extending over at least part of the circumference, into the groove of the chisel bushing does not take place by a radial springing of the entire plastic ring, but by the fact that the rib itself is resilient is and springs radially over the outer circumference of the plastic ring. This can be done in principle in two ways. On the one hand that the total thickness of the plastic ring is thicker than the depth of the annular groove of the drill collar, or in that the plastic ring, even if its slot is compressed, at least with its rib still protruding beyond the outer diameter of the drill collar. According to a first preferred embodiment, the cross section of the plastic ring is wave-shaped, wherein a radially outwardly projecting wave crest forms the radially inwardly compressible and outwardly resilient portion of the cross section of the plastic ring.
Eine weitere bevorzugte Ausfuhrungsform ist dadurch gekennzeichnet, dass der Kunststoffring - der eine etwa zylinderartig gestaltete Außenfläche aufweist - mit einer radial über die Außenfläche vorstehenden Rippe versehen ist, die den in radialer Richtung nach innen bewegbaren und nach außen federnden Abschnitt des Querschnitts des Kunststoffringes bildet, wobei zweckmäßig die Rippe schräg zur Achse des Kunststoffringes geneigt ausgebildet ist, vorzugsweise unter einem Winkel zwischen 35° und 75°.A further preferred embodiment is characterized in that the plastic ring - which has an approximately cylindrical outer surface - is provided with a radially over the outer surface projecting rib which forms the radially inwardly movable and outwardly resilient portion of the cross section of the plastic ring, wherein expediently the rib is inclined at an angle to the axis of the plastic ring, preferably at an angle between 35 ° and 75 °.
Vorzugsweise erstreckt sich der in radialer Richtung nach innen drückbare und nach außen federnde Abschnitt nur über einen Teil des Umfangs des Kunststoffringes, vorzugsweise über mindestens 80 % des Umfangs.Preferably, the radially inwardly compressible and outwardly resilient portion extends only over a portion of the circumference of the plastic ring, preferably over at least 80% of the circumference.
In der Praxis hat es sich gezeigt, dass für den Kunststoffring mit einer Wandstärke zwischen 0,7 und 3 mm, vorzugsweise zwischen 1,3 und 1,8 mm, das Auslangen gefunden wird, wobei im Fall der Ausbildung einer radial nach außen vorstehenden Rippe diese eine geringere Wandstärke aufweist als der übrige Querschnitt des Kunststoffringes.In practice, it has been found that for the plastic ring with a wall thickness between 0.7 and 3 mm, preferably between 1.3 and 1.8 mm, the Auslangen is found, wherein in the case of forming a radially outwardly projecting rib this has a smaller wall thickness than the remaining cross-section of the plastic ring.
Zweckmäßig ist der Kunststoffring aus einem der folgenden Materialien gebildet: Polyamid (PA), Polyacetal (POM), Thermoplastische Polyester (PET), HT-Polymere (PEEK, PSU), Polyethylen (PE), Polypropylen (PP), Polyvinylchlorid (PVC).The plastic ring is expediently formed from one of the following materials: polyamide (PA), polyacetal (POM), thermoplastic polyesters (PET), HT polymers (PEEK, PSU), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) ,
Für besonders harte Betriebseinsätze ist der Kunststoffring dadurch gekennzeichnet, dass er mit einer Faserverstärkung ausgebildet ist, beispielsweise einer Glasfaserverstärkung.For particularly hard operational use of the plastic ring is characterized in that it is formed with a fiber reinforcement, such as a glass fiber reinforcement.
Die Erfindung ist nachfolgend anhand zweier in der Zeichnung dargestellter Ausfuhrungsbeispiele näher erläutert, wobei Fig. 1 einen Querschnitt durch einen Kunststoffring, Fig. 2 eine Draufsicht und Fig. 3 einen Schrägriss des Kunststoffringes gemäß einer ersten Ausführungsform veranschaulichen. In Fig. 4 ist der Kunststoffring im eingebauten Zustand gezeigt. Fig. 5 stellt wiederum einen Querschnitt des Kunststoffringes und Fig. 6 eine Draufsicht auf denselben gemäß einer zweiten Ausföhrungsform dar. Fig. 7 veranschaulicht wiederum den Kunststoffring im eingebauten Zustand. Wie aus Fig. 4 zu erkennen ist, weist ein Rundschafϊtmeißel 1 eine am Meißelschaft 2 umlaufende Ringnut 3 auf, die eine bestimmte Tiefe 4 und eine bestimmte Breite 5 aufweist. In der Höhe dieser Ringnut 3 ist eine Meißelbüchse 6, in die der Rundschaftmeißel 1 eingesetzt ist, innenseitig ebenfalls mit einer Ringnut 7 versehen, die jedoch nur eine geringere Breite 8 als die Ringnut 3 aufweist. Zur lösbaren Befestigung des Rundschaftmeißels 1 in der Meißelbüchse 6 ist ein Kunststoffring 9 vorgesehen, der gemäß der in den Fig. 1 bis 4 dargestellten Ausführungsform einen wellenförmigen Querschnitt aufweist. Etwa mittig der Breite 10 dieses Kunststoffringes 9 ragt ein Abschnitt 11 — nachstehend auch als Rippe 11 bezeichnet - mit seinem Außendurchmesser 12 über die Außendurchmesser 13 der beiden Enden des Kunststoffringes 9 vor. Der Kunststoffring 9 ist, wie aus Fig. 2 zu erkennen ist, mit einem Schlitz 14 versehen. Seine größte Dicke 15 überragt die Tiefe 4 der Ringnut 3 des Rundschaftmeißels 1, wenn der Kunststoffring 9 sich in entspannter Position befindet, wie sie in den Figuren dargestellt ist, sodass er den Innendurchmesser 6' der Meißelbüchse überragt.The invention is explained in more detail below with reference to two exemplary embodiments illustrated in the drawing, FIG. 1 illustrating a cross section through a plastic ring, FIG. 2 a top view and FIG. 3 a perspective view of the plastic ring according to a first embodiment. 4, the plastic ring is shown in the installed state. Fig. 5 again shows a cross-section of the plastic ring and Fig. 6 is a plan view of the same according to a second Ausföhrungsform. Fig. 7 illustrates in turn the plastic ring in the installed state. As can be seen from Fig. 4, a Rundschafϊtmeißel 1 has a circumferential on the drill collar 2 annular groove 3, which has a certain depth 4 and a certain width 5. In the amount of this annular groove 3 is a chisel 6, in which the round shank chisel 1 is inserted, also provided on the inside with an annular groove 7, which, however, has only a smaller width 8 than the annular groove 3. For releasable attachment of the round shank chisel 1 in the chisel sleeve 6, a plastic ring 9 is provided, which has according to the embodiment shown in FIGS. 1 to 4 has a wave-shaped cross-section. Approximately in the middle of the width 10 of this plastic ring 9 protrudes a portion 11 - hereinafter also referred to as rib 11 - with its outer diameter 12 on the outer diameter 13 of the two ends of the plastic ring 9 before. The plastic ring 9 is, as can be seen from Fig. 2, provided with a slot 14. Its largest thickness 15 projects beyond the depth 4 of the annular groove 3 of the round shank chisel 1, when the plastic ring 9 is in a relaxed position, as shown in the figures, so that it projects beyond the inner diameter 6 'of the chisel.
Das Einsetzen und Entfernen des Rundschaftmeißels 1 in die bzw. aus der Meißelbüchse 6 ist dadurch möglich, dass die vorragende Rippe 11 zurückdrückbar ist, und zwar so weit zurückdrückbar, dass sie innerhalb der Ringnut 3 des Rundschaftmeißels 1 zu liegen kommt. Hierdurch kommt es zu einer Vergrößerung der Breite 10 des Kunststoffringes 9, weshalb die Breite 5 der Ringnut 3 des Rundschaftmeißels 1 derart bemessen ist, dass der Kunststoffring 9 auch im sozusagen flachgedrückten Zustand innerhalb der Ringnut 3 Platz findet. Dieser flachgedrückte Zustand des Kunststoffringes 9, also der zurückgedrückten Rippe 11, ist in Fig. 4 mit strichlierten Linien veranschaulicht.The insertion and removal of the round shank chisel 1 in and out of the chisel sleeve 6 is possible in that the projecting rib 11 is zurückdrückbar, namely so far zurückdrückbar that it comes to rest within the annular groove 3 of the round shank chisel 1. This results in an increase in the width 10 of the plastic ring 9, which is why the width 5 of the annular groove 3 of the round shank chisel 1 is dimensioned such that the plastic ring 9 also takes place in the flat-pressed state within the annular groove 3, so to speak. This flattened state of the plastic ring 9, so the back-pressed rib 11 is illustrated in Fig. 4 with dashed lines.
Gemäß der in den Fig. 5 bis 7 dargestellten Ausführungsform weist der Kunststoffring 9 eine von einem etwa zylindrisch gestalteten ringförmigen Basiskörper 16 des Kunststoffringes 9 radial nach außen vorragende und schräg nach einem Ende des Kunststoffringes 9 gerichtete Rippe 17 auf, deren Wandstärke 18 etwas geringer gehalten ist als die Wandstärke 19 des zylindrischen Basiskörpers 16. Auch dieser Kunststoffring 9 ist geschlitzt ausgebildet, um ihn auf den Rundschaftmeißel 1 aufschieben zu können. Wie aus Fig. 7 zu erkennen ist, liegt der ring-zylindrische Basiskörper 16 an dem Nutgrund der Ringnut 3 des Rundschaftmeißels 1 an, und es ragt die Rippe 17 im entspannten Zustand in die Ringnut 7 der Meißelbüchse 6.According to the embodiment shown in FIGS. 5 to 7, the plastic ring 9 has a radially outwardly projecting from an approximately cylindrical annular base body 16 of the plastic ring 9 and obliquely directed towards one end of the plastic ring 9 rib 17 whose wall thickness 18 is kept slightly lower is as the wall thickness 19 of the cylindrical base body 16. Also, this plastic ring 9 is slotted, in order to postpone it on the round shank chisel 1 can. As can be seen from Fig. 7, the ring-cylindrical base body 16 is located on the groove bottom of the annular groove 3 of the round shank chisel 1, and it protrudes the rib 17 in the relaxed state in the annular groove 7 of the chisel. 6
