Description

Die Erfindung bezieht sich auf einen Tangential-Rollkopf nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a tangential rolling head according to the preamble of the claim 1.

Ein Tangential-Rollkopf ist aus DE-U-29610183 bekannt.A tangential rolling head is known from DE-U-29610183.

Tangential-Rollköpfe weisen zwei Formrollen auf, die an den Enden von Hebelarmen drehbar gelagert sind. Die Hebelarme sind um eine gemeinsame Achse eines Grundkörpers verschwenkbar, um den Abstand zwischen den Formrollen zu verstellen. Der Grundkörper ist mit Mitteln zum Einspannen in einer Werkzeugmaschine versehen, wobei diese üblicherweise einen Schaft aurweisen, der seitlich vom Grundkörper absteht. Bei dem Bearbeitungsprozeß wird das Werkstück drehend angetrieben, und die Formrollen bewegen sich quer in Richtung Werkstück, wobei die Bearbeitung beendet ist, wenn Formrollen und Achse des Werkstücks in einer Ebene liegen. Diese Endposition wird normalerweise nach 15 bis 30 Umdrehungen des Werkstücks erreicht.Tangential roller heads have two form rollers, which at the ends of Lever arms are rotatably mounted. The lever arms are around a common one Axis of a base body pivotable to the distance between the To adjust form rollers. The basic body is with means for clamping provided in a machine tool, which usually a Show shaft that protrudes laterally from the body. In the editing process the workpiece is driven in rotation, and the form rollers move transversely in the direction of the workpiece, whereby the machining ends is when the form rollers and the axis of the workpiece lie in one plane. This End position is usually after 15 to 30 revolutions of the workpiece reached.

Zur Herstellung unterschiedlicher Gewinde und Gewinde unterschiedlichen Durchmessers sind die Formrollen auszutauschen bzw. den Abstand der Formrollen voneinander zu verändern durch Verstellung der Hebelarme über geeignete Verstellschrauben, wobei jedem zugeordneten Hebelarm eine Verstellschraube zugeordnet ist.To produce different threads and different threads The form rollers have to be exchanged or the distance between them Change form rollers from each other by adjusting the lever arms over suitable adjustment screws, with each assigned lever arm an adjustment screw assigned.

Aus der Firmenschrift Fette "verstellbarer Tangential-Rollkopfhalter für NC- und CNC-Drehautomaten" ist ein Rollkopfhalter bekannt geworden, bei dem in einer Ausnehmung des Grundkörpers ein Klemmbolzen befestigbar ist, der seinerseits ein Federblech in einer Ausnehmung aufnimmt. Das Federblech ist mit Hilfe einer Spannhülse im Klemmbolzen befestigt. Das Federblech ist außerhalb des Klemmbolzens gabelförmig und wirkt mit einer Ringnut einer die Hebelarme durchsetzenden Spindel zusammen. Das Federblech hat die Aufgabe, die eingestellte Axialposition der Formrollen aufrechtzuerhalten und nachzugeben, wenn die Relativausrichtung von Werkstück und Formrollen nicht mittig ist. Da bei einer Verschwenkung der die Formrollen tragenden Hebel eine Relativverschiebung gegenüber dem Halter stattfindet, ist das Federblech gabelförmig, um die unterschiedlichen Positionen zu kompensieren.Adjustable tangential roll head holder for NC and CNC automatic lathes "a roll head holder has become known in which a clamping bolt can be fastened in a recess in the base body, which in turn receives a spring plate in a recess. The spring plate is fastened in the clamping bolt with the help of an adapter sleeve. The spring plate is fork-shaped outside the clamping bolt and works with one Ring groove of a spindle passing through the lever arms together. The spring plate has the task of maintaining the set axial position of the form rollers and yield when the relative alignment of the workpiece and form rollers is not in the center. Because with a pivoting of the Shaped roller-carrying lever a relative displacement relative to the holder takes place, the spring plate is fork-shaped to the different positions to compensate.

Mit zunehmender Geschwindigkeit von NC-Maschinen bzw. Rollköpfen ergeben sich hohe Momente beim Anfahren und Stoppen, was zu einer erheblichen Belastung des Federblechs führt. Es kommt mithin immer wieder zu Brüchen, wodurch der Fertigungsprozeß unterbrochen wird.Resulting with increasing speed of NC machines or rolling heads high moments when starting and stopping, resulting in a significant Load on the spring plate leads. It always happens Fractures, which interrupt the manufacturing process.

Der Erfindung liegt die Aufgabe zugrunde, einen Tangential-Rollkopf zu schaffen, bei dem die Halterung auch bei hoher Belastung ihre Funktion aufrechterhält.The invention has for its object to a tangential rolling head create in which the bracket maintains its function even under high loads.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of patent claim 1.

Bei der Erfindung ist das Blechteil steif ausgebildet. Es soll sich mithin bei einer Relativbewegung der Ringnut gegenüber dem Blechteil gar nicht oder nur vernachlässigbar verbiegen. Statt dessen befinden sich Tellerfedern auf beiden Seiten des Blechteils im Bereich der Ausnehmung, wodurch das Blech als Ganzes mehr oder weniger verschwenkbar wird, wenn eine Auslenkung aus der mittigen Lage erforderlich werden sollte.In the invention, the sheet metal part is rigid. It is said to be a relative movement of the annular groove with respect to the sheet metal part not at all or bend only negligibly. Instead there are disc springs both sides of the sheet metal part in the region of the recess, which means that Sheet metal as a whole becomes more or less pivotable when there is a deflection should be required from the central position.

Mit Hilfe der Erfindung wird der Rollkopf nicht nur in Position mittig zum Werkzeug gehalten, wenn der Achsabstand des Rollkopfs verändert wird, vielmehr wird auch eine Federung erhalten für den Fall, daß das Werkzeug nicht mittig zum Rollkopf steht. Die Federbelastung wird von den Tellerfedem aufgenommen, die eine hohe Standzeit aufweisen. Es wird eine relativ geringe Winkeländerung des Federblechs erzielt und damit ein Verkanten in der Spindelnut vermieden.With the help of the invention, the rolling head is not only in the center Tool held when the center distance of the rolling head is changed, rather, suspension is also obtained in the event that the tool is not in the middle of the rolling head. The spring load is from the disc springs recorded that have a long service life. It will be a relative achieved slight change in the angle of the spring plate and thus tilting in the spindle groove avoided.

Bei dem erfindungsgemäßen Tangential-Rollkopf wird wie auch bei bekannten Rollköpfen ein Längenausgleich erhalten, wenn der Achsabstand im Rollkopf verändert wird.In the tangential rolling head according to the invention, as in known ones Roll heads receive a length compensation if the center distance in Roll head is changed.

Zwischen Rollkopf und Grundkörper besteht keine feste Verbindung.Der Rollkopf kann daher auf einfache Weise aus dem Halter genommen werden, z. B. beim Rollenwechsel, Einstellung mit einer Lehre usw.. Beim Einsetzen des Rollkopfes greift das Blechteil ohne Hilfsmittel in die Spindelnut ein.There is no fixed connection between the rolling head and the base body Roll head can therefore be easily removed from the holder, z. B. when changing roles, setting with a gauge, etc. When inserting of the rolling head, the sheet metal part engages in the spindle groove without tools.

Ein weiterer besonderer Vorteil ist, daß die erfindungsgemäße Halterung für den Tangential-Rollkopf sehr kompakt baut. Der gegenüber herkömmlichen Rollköpfen freibleibende Platz kann für die Befestigung verschiedener Typen genutzt werden.Another particular advantage is that the holder according to the invention for builds the tangential rolling head very compact. Compared to conventional Rolling heads free space can be used for attaching various types be used.

Der in Fign. 1 und 2 dargestellt Rollkopf 10 weist einen Grundkörper 12 auf, der mit zwei Gabelarmen 14, 16 versehen ist sowie mit einem quer dazu abstehenden Schaft 18 zur Einspannung in eine nicht gezeigte Werkzeugmaschine. Der Rollkopf 10 weist ferner zwei Hebel 20, 22 auf von denen der vordere Hebelarm 24, 26 eine Formrolle 28 bzw. 30 lagert, die einen vorgegebenen Abstand voneinander haben. Die Hebel 20, 22 sind um einen Bolzen 32, der sich durch beide Gabelarme 14, 16 erstreckt, schwenkbar gelagert. Insoweit ist der beschriebene Tangential-Rollkopf Stand der Technik DE-U-29610183. Auf die Betätigung der Formrollen 28, 30 beim Formprozeß soll im einzelnen nicht eingegangen werden.The in Fig. 1 and 2, rolling head 10 has a base body 12, which is provided with two fork arms 14, 16 and one which projects transversely thereto Shaft 18 for clamping in a machine tool, not shown. The rolling head 10 also has two levers 20, 22, of which the front lever arm 24, 26 a form roller 28 and 30 supports a predetermined Distance from each other. The levers 20, 22 are around a bolt 32, which extends through both fork arms 14, 16, pivotally mounted. In this respect, the tangential rolling head described is state of the art DE-U-29610183. The actuation of the shaping rollers 28, 30 during the shaping process should in detail not be received.

Die hinteren Hebelarme 34, 36 sind von einer Spindel 38 durchsetzt. Die Hebelarme 34, 36 weisen nicht gezeigt Gewindebohrungen auf, die mit Gewindeabschnitten der Spindel 38 (ebenfalls nicht gezeigt) zusammenwirken, wobei die Gewindeabschnitte gegenläufig sind, so daß bei einer Verdrehung der Spindel 38 die Formrollen 28, 30 entweder aufeinander zu- oder voneinander fortbewegt werden je nach Drehrichtung der Spindel 38.The rear lever arms 34, 36 are penetrated by a spindle 38. The Lever arms 34, 36 have threaded bores, not shown, which have threaded sections the spindle 38 (also not shown) cooperate, wherein the threaded sections are in opposite directions, so that when twisted the spindle 38 the form rollers 28, 30 either towards each other or from each other are moved depending on the direction of rotation of the spindle 38.

Die Spindel 38 weist annähernd mittig eine Ringnut auf (ebenfalls nicht gezeigt), die mit einem gabelartigen Abschnitt eines Blechteils 40 zusammenwirkt, daß weiter unten noch beschrieben werden soll. Die Ringnut liegt auf der Höhe der Achse 42, welche die Mitte darstellt zwischen den Formrollen 28, 30. Bei einer Änderung dieses Abstandes ist wichtig, daß jede Rolle 28, 30 jeweils um den gleichen Betrag verstellt wird, um die Mittenlage der Formrollen 28, 30 nicht zu verändern, wodurch sonst eine Achsverschiebung gegenüber dem Werkstück zustande käme.The spindle 38 has an annular groove approximately in the center (likewise not shown), which cooperates with a fork-like section of a sheet metal part 40, that will be described below. The ring groove lies on the height of the axis 42, which is the center between the form rollers 28, 30. When changing this distance it is important that each roller 28, 30 is adjusted by the same amount to the middle position of the Form rollers 28, 30 not to be changed, which would otherwise result in an axis shift compared to the workpiece.

Aus Fig. 4 ist der Gabelabschnitt des Blechteils 40 zu erkennen. Dieser ist so ausgebildet, daß er, wie schon erwähnt, passend in die nicht gezeigte Ringnut der Spindel 38 eingreift. Das Blechteil 40, das relativ dick und mithin sehr steif ausgeführt ist, weist einen Befestigungsabschnitt 46 auf mit einer Durchbohrung 48. Der Befestigungsabschnitt 46 sitzt in einer Ausnehmung 50 eines Einsatzteils 52 ein. Das Einsatzteil 52 ist zylindrisch, wie in Fig. 4 zu erkennen, und besitzt eine diametral sich erstreckende Durchbohrung 54, in der ein Stift 56 eingepaßt ist. Der Stift 56 erstreckt sich durch die Bohrung 58 des Befestigungsteils des Abschnitts 46. Beiderseits des Blechteils 40 sind Tellerfederpakete 58, 60 angeordnet, über die sich das Blechteil 40 an der Ober- und Unterseite der Ausnehmung 40 abstützt. Wie aus Fig. 1 hervorgeht, ist das Einsatzteil 52 in einer entsprechenden Ausnehmung 62 des Rundkörpers 12 aufgenommen und mit Hilfe einer Stiftschraube 64 festgelegt.The fork section of the sheet metal part 40 can be seen from FIG. This is so trained that, as already mentioned, it fits into the annular groove, not shown the spindle 38 engages. The sheet metal part 40, which is relatively thick and therefore is very rigid, has a fastening section 46 with a Through hole 48. The fastening section 46 is seated in a recess 50 of an insert part 52. The insert 52 is cylindrical, as in FIG. 4 to recognize, and has a diametrically extending bore 54, in which a pin 56 is fitted. The pin 56 extends through the bore 58 of the fastening part of the section 46. On both sides of the sheet metal part 40 plate spring assemblies 58, 60 are arranged, via which the sheet metal part 40 adjoins the top and bottom of the recess 40 is supported. As can be seen from Fig. 1 is the insert 52 in a corresponding recess 62 of the Round body 12 added and fixed with the help of a stud 64.

Liegt eine Außermittigkeit zwischen Werkstück und Formrollen 28, 30 vor, werden die Hebelarme 20, 22 gemeinsam etwas verschwenkt, wodurch sich die Ringnut axial bewegt und dadurch das Blechteil 40 verschwenkt. Diese Verschwenkung ist jedoch minimal, so daß eine Verklemmung in der Ringnut nicht erfolgt. Die abrupten Belastungen beim Anfahren und beim Stoppen der Werkzeugmaschine können durch die Tellerfederpakete 58, 60 auf einfache Weise abgefangen werden.If there is an eccentricity between the workpiece and form rollers 28, 30, the lever arms 20, 22 are jointly pivoted somewhat, as a result of which the annular groove moves axially, thereby pivoting the sheet metal part 40. This Swiveling is minimal, however, so that jamming in the annular groove not happened. The abrupt loads when starting and stopping the machine tool can by the plate spring assemblies 58, 60 be caught easily.
