Bürstentgratemaschine  Bürstentgratemaschine
Die Erfindung betrifft eine Bürstentgratemaschine zum gleichzeitigen Entgraten von sich gegenüberliegenden Enden eines in Längsrichtung ausgebildeten Langprofils während eines Transportes in einer Transportrichtung. The invention relates to a brush deburring machine for simultaneous deburring of opposite ends of a longitudinal profile formed in the longitudinal direction during transport in a transport direction.
Bürstentgratemaschinen sind im Stand der Technik bereits bekannt. Bürstentgratemaschinen werden in der Regel nicht selbständig eingesetzt, sondern häufig in Kombination mit Rohrschneidemaschinen, die in hoher Taktung Rohrabschnitte von einem Metallrohr ablängen. Der abgelängte Abschnitt wird dann weiter behandelt. Die Weiterbehandlung kann in verschiedenen aufeinanderfolgenden Verfahrensschritten erfolgen, insbesondere können Rohrenden angefast werden und/oder gewaschen und/oder eben entgratet werden. Durch die Bürstentgratemaschine werden Enden und Schnittflächen der Metallrohre während ihres Transportes mittels Transportscheiben von scharfen Kanten und von im Schneidprozess übrig gebliebenen Rohrspänen befreit. Eine derartige Bürstentgratemaschine ist aus der US 3,045,268 bekannt. Brush deburring machines are already known in the art. As a rule, brush deburring machines are not used on their own, but often in combination with pipe cutting machines that cut lengths of pipe from a metal pipe to a high degree. The cut-to-length section will then be further discussed. The further treatment can take place in various successive process steps, in particular pipe ends can be chamfered and / or washed and / or just deburred. The brush deburring machine frees the ends and cut surfaces of the metal tubes during their transport by means of transport discs from sharp edges and pipe chips left over in the cutting process. Such a brush deburring machine is known from US 3,045,268.
Aus der DE 195 16 607 C1 ist eine Bürstentgratemaschine bekannt mit seitlich rotierenden Walzenbürsten an denen jeweils Mitnehmer vorbeilaufen, die paarweise gegenüber einander angeordnet sind und jeweils ein Rohr an den Walzenbürsten vorbeitransportieren, um die Rohrenden zu entgraten. From DE 195 16 607 C1 a brush deburring machine is known with laterally rotating roller brushes which pass each driver, which are arranged in pairs opposite each other and each transport a pipe past the roller brushes to deburr the pipe ends.
In der DE 34 30 065 A1 ist eine Entgratemaschine offenbart, die ebenfalls zwei seitlich rotierende Bürsten offenbart, wobei die Rohre mittels Mitnehmern in Längsrichtung der Walzenbürsten transportiert werden und dabei durch die rotierenden Walzenbürsten entgratet werden. Diese Bürstentgratemaschinen eignen sich zum Entgraten von Rohren ab einer Länge von etwa 90 mm. Sie sind für Rohrabschnitte mit geringeren Längen nicht geeignet. In DE 34 30 065 A1 a deburring machine is disclosed, which also discloses two laterally rotating brushes, wherein the tubes are transported by means of carriers in the longitudinal direction of the roller brushes and thereby deburred by the rotating roller brushes. These brush deburring machines are suitable for deburring pipes with a length of approx. 90 mm. They are not suitable for pipe sections with shorter lengths.
Es ist daher Aufgabe der Erfindung, eine Bürstentgratemaschine zur Verfügung zu stellen, mit der auch Langprofilabschnitte geringerer Länge entgratet werden können. It is therefore an object of the invention to provide a brush deburring machine available, with which also long profile sections lesser length can be deburred.
Die Aufgabe wird durch eine eingangs genannte Bürstentgratemaschine mit den Merkmalen des Anspruchs 1 erfüllt. Die erfindungsgemäße Bürstentgratemaschine eignet sich insbesondere zum Entgraten von abgelängten Abschnitten eines insbesondere metallischen Langprofils. Unter Langprofilen werden hier Hohlprofile, insbesondere Rohre, aber auch Vollprofile, im Querschnitt gewinkelte Profile usw. verstanden. Dabei können die Langprofilabschnitte mit Hilfe einer der Bürstentgratemaschine vorgeschalteten Schneidemaschine oder Sägemaschine vom Langprofil abgelängt werden. Die erfindungsgemäße Bürstentgratemaschine ist vorzugsweise Bestandteil eines Sägebearbeitungszentrums, bei dem die Langprofilabschnitte mit hoher Taktung, d. h. von bis zu 230 Abschnitten im Vierfachschnitt pro Minute, abgelängt werden und auch mit einer derart hohen Stückzahl pro Minute entgratet werden müssen, um einen fließenden Bearbeitungsablauf gewährleisten zu können. Dazu werden die abgelängten Langprofilabschnitte mittels zwei nebeneinander in Transportrichtung verlaufenden Reihen von Transportscheiben mittels eines durch Drehung der Transportscheiben erzeugten Vorschubs in Transportrichtung weiter transportiert. Jede der Reihen weist jeweils wenigstens zwei Transportscheiben auf, Unter wenigstens zwei ist hier und im Weiteren die Zahl Drei, Vier und jede höhere natürliche Zahl gemeint. Die Transportscheiben sind entlang jeder der beiden Reihen versetzt zueinander und in Transportrichtung einander überlappend angeordnet. Sie weisen entlang ihres Umfanges Aussparungen auf. Die Aussparungen gestatten durch Übergabe der Langprofilabschnitte von einer Transportscheibe zur in Transportrichtung unmittelbar benachbarten Tamsportscheibe einen Transport in Transportrichtung. Dabei streichen sich gegenüberliegende Enden des Langprofilabschnitts an in Transportrichtung ausgerichteten Bürstenrollen vorbei, die um ihre vorzugsweise parallel zur Transportrichtung ausgerichtete Rotationsachse rotierbar sind. Das eigentliche Entgraten der beiden sich gegenüberliegenden Enden des Langprofilabschnitts erfolgt durch die sich während des Betriebs rotierenden Bürstenrollen, die jeweils in Kontakt mit einem Ende des Langprofils stehen. The object is achieved by an initially mentioned brush deburring machine with the features of claim 1. The brush deburring machine according to the invention is particularly suitable for deburring cut-to-length sections of a particular metallic long profile. Under long profiles here hollow sections, especially pipes, but also full profiles, in cross-section angled profiles, etc. understood. The long profile sections can be cut from the long profile with the aid of a cutting machine or sawing machine upstream of the brush deburring machine. The brush deburring machine according to the invention is preferably part of a saw machining center, in which the long profile sections with high timing, ie of up to 230 sections in quadruple section per minute, are cut to length and must be deburred with such a high number per minute to ensure a smooth machining process can , For this purpose, the cut-to-length profile sections are further transported in the transport direction by means of two rows of transport disks running side by side in the transport direction by means of a feed generated by rotation of the transport disks. Each of the rows has in each case at least two transport disks, at least two here and hereinafter the number three, four and any higher natural number are meant. The transport discs are offset along each of the two rows to each other and arranged overlapping each other in the transport direction. They have recesses along their circumference. The recesses allow by transferring the long profile sections of a transport disc to the transport direction directly adjacent Tamsportscheibe transport in the transport direction. At the same time, opposite ends of the long profile section brush past brush rollers oriented in the direction of transport, which are rotatable about their axis of rotation, which is preferably aligned parallel to the transport direction. The actual deburring of the two opposite ends of the long profile section is effected by the rotating during operation brush rollers, which are each in contact with one end of the long profile.
Erfindungsgemäß können durch die Bürstentgratemaschine Langprofilabschnitte ab einer Länge von weniger als 80 mm, vorzugsweise weniger als 30 mm entgratet werden. Dazu sind die beiden Transportscheibenreihen auf einen Abstand von unter 30 mm zueinander verstellbar. Um dieses Ziel zu erreichen, werden die Transportscheiben mit einer Dicke von jeweils höchstens 1 bis 3 mm, vorzugsweise von höchstens 1 mm ausgebildet, die in jeder der beiden Reihen versetzt zueinander angeordnet sind, so dass die gesamte Dicke der sich überlappenden Transportscheiben weniger als 6 mm, vorzugsweise weniger als 2 mm beträgt. According to the invention can be deburred by the brush deburring machine long profile sections from a length of less than 80 mm, preferably less than 30 mm. For this purpose, the two transport disc rows are adjustable to a distance of less than 30 mm to each other. To achieve this goal, the transport discs are formed with a thickness of at most 1 to 3 mm, preferably of at most 1 mm, which are arranged offset in each of the two rows to each other, so that the total thickness of the overlapping transport discs less than 6 mm, preferably less than 2 mm.
In einer bevorzugten Weiterbildung der Erfindung weist die erfindungsgemäße Bürstentgratemaschine zwei in Transportrichtung verlaufende Rahmenarme auf, an denen jeweils eine Reihe drehbarer Transportscheiben angeordnet ist. Vorzugsweise sind die in Transportrichtung ersten beiden Transportscheiben durch jeweils einen Servomotor angetrieben. Die zweite, vierte, sechste usw. Transportscheibe ist mit der ersten Transportscheibe über ein Getriebe gekuppelt, während die dritte, fünfte usw. Transportscheibe mit der zweiten Transportscheibe über ein anderes Getriebe gekuppelt ist. Es sind daher vorteilhafterweise die genau in Transportrichtung in einer gemeinsamen Flucht liegenden Transportscheiben miteinander gekuppelt. Die beiden Fluchten sind versetzt nebeneinander angeordnet. Es ist aber natürlich auch denkbar, anstatt der ersten und zweiten Transportscheiben irgendwelche anderen Transportscheiben der jeweiligen Flucht anzutreiben. In a preferred development of the invention, the brush deburring machine according to the invention has two frame arms running in the transport direction, on which in each case a row of rotatable transport discs is arranged. Preferably, the first two transport discs in the transport direction are each driven by a servomotor. The second, fourth, sixth, etc. transport pulley is coupled to the first transport pulley via a gear, while the third, fifth, etc. transport pulley is coupled to the second transport pulley via another gear. There are therefore advantageously coupled exactly lying in the transport direction in a common escape transport discs together. The two escapes are offset next to each other. Of course, it is also conceivable to drive any other transport discs of the respective escape instead of the first and second transport discs.
Außen entlang jeder der Rahmenarme ist eine Bürstenrolle vorgesehen. Die beiden Rahmenarme sind an jeweils einer äußeren Wandung konkav ausgebildet, und zwar derart, dass eine dem jeweiligen Rahmenarm zugeordnete Bürstenrolle gegenüber der geraden Ausbildung der Wandung dichter an die in Transportrichtung transportierten, Langprofilabschnitte heranbringbar ist. Günstigerweise ist die äußere Wandung des Rahmenarmes über die gesamte Länge der jeweiligen Bürstenrolle konkav ausgeformt. Externally along each of the frame arms, a brush roller is provided. The two frame arms are concave on each outer wall, in such a way that a respective frame arm associated brush roller against the straight formation of the wall is closer to the transported in the transport direction, long profile sections can be brought closer. Conveniently, the outer wall of the frame arm is formed concave over the entire length of the respective brush roller.
Jede der Transportscheiben weist jeweils eine der gegenüberliegenden Reihe an Transportscheiben zugewandte Innenfläche und eine dem Rahmen zugewandte Außenfläche auf. ,lnnen' und .außen' werden in diesem Sinne hier durchgängig so verstanden. Each of the transport discs has in each case one of the opposite row of transport discs facing inner surface and an outer surface facing the frame. 'Inside' and 'outside' are understood in this sense throughout.
In einer weiteren Ausführungsform der Erfindung ist vorzugsweise jede der Transportscheiben mit jeweils einer Verdrehsicherung an einem Drehteller drehfest angeordnet. Die Verdrehsicherung weist vorzugsweise eine Bauhöhe von höchstens 4 mm, vorzugsweise höchstens 2 mm innenseitig der Innenfläche der jeweiligen Transportscheibe auf. Die Verdrehsicherung weist als wesentliche Bestandteile einen Drehteller, eine Öffnung in der Transportscheibe und einen kurzen Zylinder auf. Die Öffnung in einem in der Transportscheibenfläche verlaufenden Querschnitt ist nicht rotationssymmetrisch ausgebildet. In jeder der Transportscheiben kann eine gleiche Öffnung vorgesehen sein. Der Zylinder weist einen formgleichen Querschnitt auf, und er ist durch die Öffnung formschlüssig hindurchführbar. Ein inneres Ende des kurzen Zylinders ist als Kragen ausgebildet, der die Transportscheibenöffnung hintergreift und zur Befestigung an einen Drehteller zieht, wobei der Drehteller, der drehbar am Rahmenarm angeordnet ist, eine zentrale Aussparung aufweist, die im Querschnitt ebenfalls dem nicht rotationssymmetrischen Öffnungsquerschnitt angepasst ist und zur formschlüssigen Aufnahme des außenseitigen Endes des Zylinders vorgesehen ist. Im Zylinder ist außenseitig zentral ein Gewinde vorgesehen, in das eine Schraube drehbar ist, die den Zylinder an dem Drehteller unter Einklemmen der Transportscheibe befestigt. In a further embodiment of the invention, preferably, each of the transport discs, each with a rotation on a turntable rotatably arranged. The rotation lock preferably has a height of at most 4 mm, preferably at most 2 mm on the inside of the inner surface of the respective transport disc. The anti-rotation device has as essential components a turntable, an opening in the transport disc and a short cylinder. The opening in a cross-section running in the transport disk surface is not rotationally symmetrical. In each of the transport discs, a same opening may be provided. The cylinder has a cross section of the same shape, and it can be passed through the opening in a form-fitting manner. An inner end of the short cylinder is formed as a collar which engages behind the transport disc opening and pulls for attachment to a turntable, wherein the turntable, which is rotatably mounted on the frame arm, a having central recess, which is also adapted to the non-rotationally symmetrical opening cross section in cross section and is provided for positive reception of the outside end of the cylinder. In the cylinder, a thread is externally provided centrally into which a screw is rotatable, which secures the cylinder to the turntable while clamping the transport disc.
Aufgrund der geringen Bauhöhe des Zylinderkragens sowie der geringen Dicke der Transportscheibe und der konkaven Ausbildung eines der äußeren Bereiche des Transportrahmens ist eine Bürstentgratemaschine herstellbar, die es ermöglicht, Abschnitte mit einer Länge ab 30 mm zu entgraten. Due to the low height of the cylinder collar and the small thickness of the transport disc and the concave formation of one of the outer regions of the transport frame, a brush deburring machine can be produced, which makes it possible to deburr sections with a length from 30 mm.

Bei den Langprofilabschnitten 10 kann es sich um Metallprofile, insbesondere Rohrabschnitte, vorzugsweise Metallrohrabschnitte handeln. Letztere sind in Fig. 1 dargestellt. Die beiden Rahmenarme 2, 3 sind im Abstand voneinander in Längsrichtung L verstellbar. Unabhängig von den Transportscheiben der Reihen 4, 5 werden die Bürstenrollen 6, 7 angetrieben. Während des Transportes der Langprofilabschnitte 10 in Transportrichtung T rotieren die Bürstenrollen 6, 7. Die erste Bürstenrolle 6 entgratet dabei ein erstes äußeres Ende 8 und die zweite Bürstenrolle 7 entgratet ein zweites äußeres Ende 9 des Langprofilabschnitts The brush deburring machine 1 shown schematically in FIG. 1 has a first and a second frame arm 2, 3 aligned parallel to one another and aligned along a transport direction T. On the inner sides of each of the two frame arms 2, 3, a first row and a second row offset transport discs arranged in each other is provided. Each of the transport disks of the two rows 4, 5 is rotatably arranged on the respective frame arm 2, 3. On the outside along the first frame arm 2 is a first brush roller 6 and along the second frame arm 3 is a second brush roller 7, each aligned in the transport direction T, rotatably arranged. The transport discs are driven together and make it possible to carry sawed long profile sections 10 in the transport direction T. The long profile sections 10 are each aligned perpendicular to the transport direction T in the longitudinal direction L. The long profile sections 10 may be metal profiles, in particular pipe sections, preferably metal pipe sections. The latter are shown in FIG. The two frame arms 2, 3 are adjustable at a distance from each other in the longitudinal direction L. Regardless of the transport discs of the rows 4, 5, the brush rollers 6, 7 are driven. During the transport of the long profile sections 10 in the transport direction T, the brush rollers 6, 7 rotate. The first brush roller 6 deburrs a first outer end 8 and the second brush roller 7 deburrs a second outer end 9 of the long profile section
Die Bürstentgratemaschine 1 ist hier isoliert dargestellt, in der Regel ist sie jedoch ein Teil einer Rohrschneidemaschine, in der Langprofilabschnitte 10 in einem oder mehreren Schritten einer Weiterbehandlung unterzogen werden. Neben dem Anfasen und Waschen gehört zu den weiterbehandelnden Verfahrensschritten auch das Entgraten der Langprofilabschnitte 10. Die Langprofilabschnitte 10 sind abgesägte Abschnitte eines langen Metallrohres. Durch das Abschneiden der Abschnitte entstehen an den Schnittflächen scharfe Grate und Überbleibsel von Metallspänen. The brush deburring machine 1 is shown here in isolation, but as a rule it is part of a pipe cutting machine in which long profile sections 10 are subjected to further treatment in one or more steps. In addition to chamfering and washing, the deburring of the long profile sections 10 is also part of the further processing steps. The long profile sections 10 are sawn-off sections of a long metal tube. By cutting off the sections, sharp burrs and remnants of metal shavings are created on the cut surfaces.
Der Abstand der beiden Rahmenarme 2, 3 voneinander ist zusammen mit den Transportscheiben der Reihen 4, 5 und auch den den beiden Rahmenarmen 2, 3 zugeordneten Bürstenrollen 6, 7 verstellbar. Erfindungsgemäß ist der Abstand so weit verringerbar, dass Langprofilabschnitte 10 mit einer Länge ab 30 mm sicher in Transportrichtung T durch die Bürstentgratemaschine mit Hilfe der beiden parallel zueinander angeordneten Reihen von Transportscheiben 4, 5 transportierbar sind und ihre jeweils beiden Enden 8, 9 dennoch sorgfältig entgratet werden können. Jede einzelne der Transportscheiben der beiden Reihen 4, 5 weist Aussparungen entlang ihres jeweiligen Umfanges auf, die es ermöglichen, die Langprofilabschnitte 10 durch Übergabe von einer Transportscheibe zur nächsten in Transportrichtung zu transportieren und über die gesamte Ausdehnung der Transportrichtung T dabei die Enden 8, 9 zu entgraten. Die Aussparungen in Transportrichtung T aufeinanderfolgender Transportscheiben sind zur Übergabe der Langprofilabschnitte 10 in Größe und Anordnung aufeinander abgestimmt. Fig. 2 zeigt den zweiten, in Fig. 1 rechten Rahmenarm 3 in einer Draufsicht, und Fig. 3 zeigt denselben Rahmenarm 3 in einer Schnittansicht. Wie in den Fig. 2 und 3 dargestellt, ist die äußere Wandung des Rahmenarmes 3 in einem der Bürstenrolle 7 zugewandten bodenabseitigen Bereich 20 konkav ausgebildet in der Weise, dass der konkave Bereich 20 entlang der gesamten Ausdehnung der zweiten Bürstenrolle 7 in Transportrichtung T der Krümmung eines äußeren kreisförmigen Umfanges der Bürstenrolle 7 angepasst ist und konkav nach innen ausgeformt ist. Dadurch kann, wie in Fig. 2 gezeigt, die Bürstenrolle 7 im Vergleich zu einer geraden Wandung ein Stück näher an den transportierten Langprofilabschnitt 10 herangeführt werden. Es wird so möglich, Langprofilabschnitte 10 mit kürzerer Länge zu transportieren, da das über die zweite Reihe Transportscheiben 5 nach außen überstehende zweite Ende 9 bei gleicher Entgratequalität kürzer als herkömmliche Enden sein muss, um doch noch mit der zweiten Bürstenrolle 7 in Kontakt zu kommen. Fig. 2 zeigt neben dem zweiten Rahmenarm 3 der Bürstenrolle 7 die zweite einer Reihe von Transportscheiben 5 in einer Draufsicht, die in Transportrichtung T versetzt zueinander und sich überlappend angeordnet sind. The distance between the two frame arms 2, 3 from each other, together with the transport discs of the rows 4, 5 and also the two frame arms 2, 3 associated brush rollers 6, 7 adjustable. According to the invention the distance can be reduced so far that long profile sections 10 with a length from 30 mm safely in the transport direction T through the brush deburring machine with the help of the two mutually parallel rows of transport discs 4, 5 are transported and their respective two ends 8, 9 yet carefully deburred can be. Each of the transport discs of the two rows 4, 5 has recesses along their respective circumference, which make it possible to transport the long profile sections 10 by transfer from one transport disc to the next in the transport direction and over the entire extent of the transport direction T while the ends 8, 9th to deburr. The recesses in the transport direction T of successive transport discs are matched to each other for the transfer of the long profile sections 10 in size and arrangement. Fig. 2 shows the second, in Fig. 1 right frame arm 3 in a plan view, and Fig. 3 shows the same frame arm 3 in a sectional view. As shown in Figs. 2 and 3, the outer wall of the frame arm 3 in a brush roller 7 facing downside region 20 is concave in such a way that the concave portion 20 along the entire extent of the second brush roller 7 in the transport direction T of the curvature an outer circular circumference of the brush roller 7 is adapted and concave inwardly formed. Thereby, as shown in Fig. 2, the brush roller 7 compared to a straight wall a piece closer to the transported Long profile section 10 are introduced. It is thus possible to transport long profile sections 10 of shorter length, since the over the second row of transport discs 5 outwardly projecting second end 9 must be shorter than conventional ends with the same quality deburring to still come into contact with the second brush roller 7. Fig. 2 shows, in addition to the second frame arm 3 of the brush roller 7, the second of a series of transport discs 5 in a plan view, the offset in the transport direction T to each other and are arranged overlapping.
Fig. 3 zeigt den zweiten Rahmenarm 3 in einem Querschnitt, wobei ein Kugellager 21 für eine der Transportscheiben 23 zu erkennen ist. Die eine Transportscheibe 23 ist an einem Drehteller 22 drehfest montiert, der mittels des Kugellagers 21 drehbar im zweiten Rahmenarm 3 angerordnet ist. Fig. 3 shows the second frame arm 3 in a cross section, wherein a ball bearing 21 for one of the transport discs 23 can be seen. The one transport disc 23 is rotatably mounted on a turntable 22, which is arranged by means of the ball bearing 21 rotatably in the second frame arm 3.
Fig. 2 und 3 zeigen die dünne Ausbildung der einen Transportscheibe 23 in Längsbildung L, die etwa einen Millimeter oder weniger beträgt. 2 and 3 show the thin design of a transport disk 23 in longitudinal L, which is about one millimeter or less.
Die in Fig. 1 ansatzweise gezeigte Verdrehsicherung 30 zeigt einen innenseitig, auf jede der Transportscheiben 23 zentral aufgebrachten kurzen Zylinder 24, durch den die jeweilige Transportscheibe 23 drehbar am zweiten Rahmenarm 3 befestigt ist. Die Verdrehsicherung 30 ist in Fig. 4 im Detail dargestellt. The anti-rotation device 30 partially shown in FIG. 1 shows an inner side, on each of the transport discs 23 centrally applied short cylinder 24, through which the respective transport disc 23 is rotatably mounted on the second frame arm 3. The anti-rotation device 30 is shown in Fig. 4 in detail.
Fig. 4 zeigt die Verdrehsicherung 30 mit der einen Transportscheibe 23 in einer Explosionsdarstellung. Der Drehteller 22 ist drehbar an dem zweiten Rahmenarm 3 mittels eines Kugellagers 21 angeordnet. Auf den Drehteller 22 ist die eine Transportscheibe 23 mit einer nicht rotationssymmetrischen zentralen Öffnung 25 auflegbar, wobei der Transportteller 22 eine dem Querschnitt der Öffnung 25 der Transportscheibe 23 deckungsgleiche Aussparung 26 aufweist. Der Im Querschnitt mit der Öffnung 35 und der Aussparung 26 ebenfalls deckungsgleich ausgeformte kurze Zylinder 24 ist durch die Öffnung 25 hindurchsteckbar und in die Aussparung 26 des Drehtellers 22 formschlüssig einfügbar. Fig. 4 shows the anti-rotation 30 with a transport disk 23 in an exploded view. The turntable 22 is rotatably arranged on the second frame arm 3 by means of a ball bearing 21. On the turntable 22 which is a transport disc 23 with a non-rotationally symmetrical central opening 25 can be placed, wherein the transport plate 22 has a cross-section of the opening 25 of the transport disc 23 congruent recess 26. The cross-section with the opening 35 and the recess 26 also congruent shaped short cylinder 24 can be pushed through the opening 25 and inserted into the recess 26 of the turntable 22 form-fitting manner.
Der Zylinder 24 kann innenseitig mittels einer (nicht dargestellten) Schraube in einem zentral angeordneten Gewinde 27 des Drehteller 22 festgeschraubt werden. Die zwischen einem Zylinderinnenkragen 28 und dem Drehteller 22 vorgesehene Transportscheibe 23 ist auf diese Weise gegenüber dem Drehteller 22 verdrehsicher befestigt. Der Zylinderkragen 28 steht innenseitg von der Transportscheibe 23 je nach Ausführung um 1 - 3 mm ab. Aufgrund des kurzen Aufbaus der montierten Verdrehsicherung 30, innenseitig der Transportscheibe 23, können die beiden sich gegenüberliegenden Rahmenarme 2, 3 ganz eng aufeinander zu verschoben werden. Insgesamt können somit Langprofilabschnitte 10 ab einer Länge von L= 30 mm entgratet werden. The cylinder 24 can be screwed on the inside by means of a screw (not shown) in a centrally arranged thread 27 of the turntable 22. The provided between a cylinder inner collar 28 and the turntable 22 transport disk 23 is secured against rotation in this manner relative to the turntable 22. The cylinder collar 28 is inside of the transport disk 23 depending on the version by 1 - 3 mm from. Due to the short construction of the mounted anti-rotation device 30, on the inside of the transport disk 23, the two opposing frame arms 2, 3 can approach each other quite closely be moved. Overall, thus long profile sections 10 can be deburred from a length of L = 30 mm.
Die Bürstentgratemaschine 1 eignet sich zur Verwendung mit einer Rohrschneidemaschine, die in hoher Taktung Rohrabschnitte von einem vollständig metallischen Rohr absägt, wobei Taktzahlen von 60 Abschnitten pro Minute erzielbar sind, die nach dem Absägen von der Bürstentgratemaschine 1 aufgenommen werden und in entsprechend hoher Taktung entgratet werden können. The brush deburring machine 1 is suitable for use with a pipe cutting machine, which sawn pipe sections from a completely metallic pipe at high cycle rates, with clock rates of 60 sections per minute can be achieved, which are taken after sawing from the brush trimmer 1 and deburred in accordance with high timing can.
