Definitions
- the invention relates to a thread cutting device of a ring spinning or twisting spindle with a truncated cone-shaped thread cutting knife, which has on its lower edge a cutting edge formed by grinding only the outside.
- Such a thread separating device is already known as prior art (DE 40 15 707 C2), which has a thread separating knife which is arranged between a sleeve receptacle of the spindle and a winding point serving to fix a spinning thread.
- This thread cutting knife is designed with an edge protruding from the spindle in the radial direction and has an essentially frustoconical shape.
- the cone area has an opening angle of 45 °, the cutting edge of, for example, 30 ° requiring a clearance angle of 15 °. Due to this special configuration, the thread cutting knives had to be ground individually.
- the object of the present invention is to design a thread-cutting knife in a thread-cutting device of the type mentioned at the outset in such a way that it can be produced with a simple structure and at low cost.
- This object is achieved in that the grinding surface of the cutting edge lies in a cylinder jacket and that the opening angle of the thread cutting knife is 20 ° to 30 °.
- the bearing area in the case of a thread cutting device in which the thread cutting knife has a bearing area which can be placed on the spindle and including the truncated cone area, can be designed as a plate plane arranged at right angles to the longitudinal axis of the spindle and provided with an opening for receiving the spindle, on the outer circumference of which the Truncated cone area connects.
- spacers for adjacent thread-cutting knives made of sheet steel can be formed in the bearing area.
- These spacers can be, for example, knobs arranged in the storage area, lugs present in the area of the opening or independent spacer rings resting in the storage area of the thread-cutting knife.
- FIG. 1 shows a thread separating device 1 in the area of a ring spinning or twisting spindle 2.
- a sleeve 3 On the spindle 2, which is equipped in the lower section with an underwinding area 4, a sleeve 3 is shown schematically. Below this sleeve 3 there is a thread separating knife 5 under a cover 19, which is able to unwind 6 cut through, which is clamped between the underwind area 4 and the sleeve 3 and is exposed in this area.
- Fig. 2 shows the thread cutting knife 5 according to the invention in an enlarged view, partly in section.
- this thread separating knife 5 has a bearing area 10 which extends at right angles to the longitudinal axis A-A of the spindle.
- This storage area 10 is provided with an opening 11 for receiving the spindle 2 and forms a horizontal plate plane.
- a truncated cone area 12 On the outside of the bearing area 10 is a truncated cone area 12 in the form of a jacket.
- This truncated cone area 12 is formed on the outside 7 in the form of a cylinder jacket 9, which results in a cutting edge 8 on the lower edge.
- the outside 7 forms a grinding surface for producing the cutting edge 8. From FIG. 2 it can further be seen that between the truncated cone region 12 and the cylinder jacket 9 there is an opening angle ⁇ which is 20 ° to 30 °.
- the bearing areas 10 of the individual thread-cutting knives 5 and 5 ' are spaced apart by spacers.
- the height of the spacers is dimensioned such that the thread-cutting knives 5, 5 ′, which are combined to form the disk package S, touch only in a partial area of the truncated cone area 12.
- the spacers are designed as knobs 15 or 15 ′ arranged in the bearing area 10.
- the knobs of adjacent thread cutting knives 5, 5 ' are e.g. laterally offset from each other, so that a secure resting of the knobs representing the spacers on the relevant bearing area 10 of the underlying thread cutting knife is ensured.
- knobs 15, 15 'shown in FIG. 3 there is also the possibility according to FIG. 4 that the spacers are designed as lugs 16 arranged in the region of the opening 11, which are located on surfaces 17 and 17' of the adjacent thread cutting knife 5 and 5 'support.
- the spacers are designed in one piece with the respective thread-cutting knife 5 or 5 'and are during the manufacture of the outer edge of the ring disk, i.e. of the truncated cone area 12 is molded in using a corresponding tool.
- the spacers are designed as independent spacer rings 18 resting on the bearing area 10 of the thread-cutting knife 5 or 5 '. This also makes it possible to combine the individual thread-cutting knives one above the other to form a disk package S before the outer edge is ground in the truncated cone region 12.
- this disc package S is disassembled, so that the individual thread cutting blades are available in a usable form.
Description
Die Erfindung bezieht sich auf eine Fadentrennvorrichtung einer Ringspinn- oder -zwirnspindel mit einem kegelstumpfmantelförmigen Fadentrennmesser, das an seiner unteren Kante eine durch Anschliff nur der Außenseite gebildete Schneide aufweist.The invention relates to a thread cutting device of a ring spinning or twisting spindle with a truncated cone-shaped thread cutting knife, which has on its lower edge a cutting edge formed by grinding only the outside.
Als Stand der Technik ist bereits eine derartige Fadentrennvorrichtung bekannt (DE 40 15 707 C2), welche ein Fadentrennmesser aufweist, das zwischen einer Hülsenaufnahme der Spindel und einer zum Festlegen eines Abspinnfadens dienenden Aufwickelstelle angeordnet ist. Dieses Fadentrennmesser ist mit einem von der Spindel in radialer Richtung abragenden Rand ausgestaltet und besitzt im wesentlichen kegelstumpfartige Gestalt.Such a thread separating device is already known as prior art (DE 40 15 707 C2), which has a thread separating knife which is arranged between a sleeve receptacle of the spindle and a winding point serving to fix a spinning thread. This thread cutting knife is designed with an edge protruding from the spindle in the radial direction and has an essentially frustoconical shape.
Das Herstellen eines derartigen Fadentrennmessers ist kostenaufwendig: Der Kegelbereich besitzt einen Öffnungswinkel von 45°, wobei die Schneidkante von beispielsweise 30° einen Freiwinkel von 15° erfordert. Aufgrund dieser speziellen Konfiguration müssen bisher die Fadentrennmesser einzeln geschliffen werden.The manufacture of such a thread-cutting knife is costly: the cone area has an opening angle of 45 °, the cutting edge of, for example, 30 ° requiring a clearance angle of 15 °. Due to this special configuration, the thread cutting knives had to be ground individually.
Dementsprechend liegt der vorliegenden Erfindung die Aufgabe zugrunde, bei einer Fadentrennvorrichtung der eingangs genannten Art ein Fadentrennmesser so zu gestalten, daß es bei einfachem Aufbau mit geringem Kostenaufwand herstellbar ist.Accordingly, the object of the present invention is to design a thread-cutting knife in a thread-cutting device of the type mentioned at the outset in such a way that it can be produced with a simple structure and at low cost.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Schleiffläche der Schneide in einem Zylindermantel liegt und daß der Öffnungswinkel des Fadentrennmessers 20° bis 30° beträgt. Hierdurch ergibt sich der Vorteil, daß mehrere erfindungsgemäße Fadentrennmesser zum Paket zusammengefaßt und gemeinsam geschliffen werden können, wobei dennoch ein Schneidwinkel von 30° bis 20° entsteht. Daraus resultiert eine erhebliche Reduzierung der Herstellungskosten.This object is achieved in that the grinding surface of the cutting edge lies in a cylinder jacket and that the opening angle of the thread cutting knife is 20 ° to 30 °. This results in the advantage that a plurality of thread-cutting knives according to the invention can be combined into a package and ground together, a cutting angle of 30 ° to 20 ° nevertheless being produced. This results in a significant reduction in manufacturing costs.
In weiterer Ausgestaltung der Erfindung kann bei einer Fadentrennvorrichtung, bei welcher das Fadentrennmesser einen auf die Spindel aufsetzbaren Lagerbereich und darunter den Kegelstumpfbereich aufweist, der Lagerbereich als rechtwinkelig zur Spindellängsachse angeordnete, mit einer Öffnung zur Aufnahme der Spindel versehene Plattenebene ausgebildet sein, an deren Außenumfang der Kegelstumpfbereich anschließt.In a further embodiment of the invention, in the case of a thread cutting device in which the thread cutting knife has a bearing area which can be placed on the spindle and including the truncated cone area, the bearing area can be designed as a plate plane arranged at right angles to the longitudinal axis of the spindle and provided with an opening for receiving the spindle, on the outer circumference of which the Truncated cone area connects.
Damit ergibt sich eine wesentliche Vereinfachung in der Herstellung des erfindungsgemäßen Fadentrennmessers. Beispielsweise sind folgende Verfahrensschritte vorgesehen: Ausstanzen einer Ringscheibe aus entsprechendem Stahlblech, kegeliges Abkanten des äußeren Randes der Ringscheibe, Härten der Kegelscheiben, Zusammenfügen der Kegelscheiben zu einem Paket sowie Überschleifen des Kegelscheibenpaketes an seinem Außenumfang durch eine Schleifscheibe oder eine Schleifwalze.This results in a significant simplification in the manufacture of the thread cutting knife according to the invention. For example, the following process steps are provided: punching out an annular disk from the corresponding steel sheet, tapering the outer edge of the annular disk, hardening the conical disks, assembling the conical disks into a package and grinding the conical disk package on its outer circumference by means of a grinding disk or a grinding roller.
Um zu gewährleisten, daß die Fadentrennmesser während des Schleifvorganges möglichst nur im Bearbeitungsbereich aneinanderliegen, können in dem Lagerbereich Distanzhalter für aus Stahlblech bestehende angrenzende Fadentrennmesser eingeformt sein. Diese Distanzhalter können beispielsweise im Lagerbereich angeordnete Noppen, im Bereich der Öffnung vorhandene Nasen oder selbständige, im Lagerbereich des Fadentrennmessers aufliegende Distanzringe sein.In order to ensure that the thread-cutting knives lie against each other only in the processing area as far as possible during the grinding process, spacers for adjacent thread-cutting knives made of sheet steel can be formed in the bearing area. These spacers can be, for example, knobs arranged in the storage area, lugs present in the area of the opening or independent spacer rings resting in the storage area of the thread-cutting knife.
In weiterer Ausgestaltung der Erfindung besteht - wie vorstehend angegeben - die Möglichkeit der Anordnung mehrerer Fadentrennmesser zu einem Scheibenpaket, bei welchem ein Teil der Innenwandung des Kegelstumpfbereichs eines Fadentrennmessers auf der Außenwandung des Kegelstumpfbereichs des angrenzenden Fadentrennmessers aufliegt und die Lagerbereiche der Fadentrennmesser über die Distanzhalter im Abstand voneinander angeordnet sind. Infolge der Höhe der Distanzhalter berühren sich die zu einem Scheibenpaket zusammengefaßten Fadentrennmesser vorteilhafterweise nur in einer Teilfläche des Kegelstumpfbereichs.In a further embodiment of the invention - as stated above - there is the possibility of arranging a plurality of thread-cutting knives to form a disc package in which a part of the inner wall of the truncated cone area of a thread-cutting knife rests on the outer wall of the truncated-cone area of the adjacent thread-cutting knife and the bearing areas of the thread-cutting knife are spaced apart by the spacers are arranged from each other. As a result of the height of the spacers, the thread-cutting knives combined to form a disc package advantageously only touch in a partial area of the truncated cone area.
In weiterer Ausgestaltung der Erfindung besteht auch die Möglichkeit, in die gehärteten Scheiben an sich bekannte V-Nuten einzufräsen.In a further embodiment of the invention there is also the possibility of milling known V-grooves into the hardened disks.
Die Erfindung wird nachfolgend anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben.The invention is described below with reference to exemplary embodiments shown in the drawing.

In Fig. 1 ist eine Fadentrennvorrichtung 1 im Bereich einer Ringspinn- oder -zwirnspindel 2 dargestellt. Auf der Spindel 2, welche im unteren Abschnitt mit einem Unterwindebereich 4 ausgestattet ist, lagert eine schematisch dargestellte Hülse 3. Unterhalb dieser Hülse 3 befindet sich unter einer Abdeckung 19 ein Fadentrennmesser 5, welches in der Lage ist, einen Abspinn6 durchzutrennen, der zwischen dem Unterwindebereich 4 und der Hülse 3 festgespannt ist und in diesem Bereich freiliegt.1 shows a thread separating
Fig. 2 zeigt das erfindungsgemäße Fadentrennmesser 5 in vergrößerter Ansicht, teils geschnitten. Wie ersichtlich, weist dieses Fadentrennmesser 5 einen Lagerbereich 10 auf, welcher rechtwinklig zur Spindellängsachse A-A verläuft. Dieser Lagerbereich 10 ist mit einer Öffnung 11 zur Aufnahme der Spindel 2 versehen und bildet eine horizontale Plattenebene.Fig. 2 shows the
An den Lagerbereich 10 schließt außenseitig ein Kegelstumpfbereich 12 in Mantelform an. Dieser Kegelstumpfbereich 12 ist an seiner Außenseite 7 in Form eines Zylindermantels 9 ausgebildet, wodurch sich an der unteren Kante eine Schneide 8 ergibt. Die Außenseite 7 bildet eine Schleiffläche zur Herstellung der Schneide 8. Aus Fig. 2 geht weiter hervor, daß zwischen dem Kegelstumpfbereich 12 und dem Zylindermantel 9 ein Öffnungswinkel α vorliegt, welcher 20° bis 30° beträgt.On the outside of the
Infolge der in Fig. 2 dargestellten Konfiguration, wonach die Schleiffläche der Schneide 8 in einem Zylindermantel 9 liegt und der Öffnungswinkel α des Fadentrennmessers 5 20° bis 30° beträgt, besteht nach Fig. 3, 4 und 5 die Möglichkeit, mehrere Fadentrennmesser 5, 5' usw. zu einem Scheibenpaket S zusammenzufügen. Bei diesem Scheibenpaket S liegt ein Teil der Innenwandung 14 des Kegelstumpfbereichs 12 eines Fadentrennmessers 5 auf der Außenwandung 13 des Kegelstumpfbereichs 12 des angrenzenden Fadentrennmessers 5'.As a result of the configuration shown in FIG. 2, according to which the grinding surface of the
Die Lagerbereiche 10 der einzelnen Fadentrennmesser 5 bzw. 5' liegen über Distanzhalter im Abstand voneinander. Hierbei ist die Höhe der Distanzhalter so bemessen, daß sich die zu dem Scheibenpaket S zusammengefaßten Fadentrennmesser 5, 5' usw. nur in einer Teilfläche des Kegelstumpfbereichs 12 berühren.The
Nach Fig. 3 sind die Distanzhalter als im Lagerbereich 10 angeordnete Noppen 15 bzw. 15' ausgebildet. Die Noppen benachbarter Fadentrennmesser 5, 5' sind hierbei z.B. seitlich gegeneinander versetzt, so daß ein sicheres Aufruhen der die Distanzhalter darstellenden Noppen auf den betreffenden Lagerbereich 10 des darunterliegenden Fadentrennmessers gewährleistet ist.According to FIG. 3, the spacers are designed as knobs 15 or 15 ′ arranged in the
Statt der in Fig. 3 dargestellten Noppen 15, 15' besteht nach Fig. 4 auch die Möglichkeit, daß die Distanzhalter als im Bereich der Öffnung 11 angeordnete Nasen 16 ausgebildet sind, welche sich auf Flächen 17 bzw. 17' des angrenzenden Fadentrennmessers 5 bzw. 5' abstützen.Instead of the knobs 15, 15 'shown in FIG. 3, there is also the possibility according to FIG. 4 that the spacers are designed as
Bei der in Fig. 3 und 4 dargestellten jeweiligen Ausführungsmöglichkeit sind die Distanzhalter einstückig mit dem jeweiligen Fadentrennmesser 5 bzw. 5' gestaltet und werden während der Herstellung des äußeren Randes der Ringscheibe, d.h. des Kegelstumpfbereichs 12 über ein entsprechendes Werkzeug eingeformt.3 and 4, the spacers are designed in one piece with the respective thread-
Nach Fig. 5 besteht die Möglichkeit, daß die Distanzhalter als auf dem Lagerbereich 10 des Fadentrennmessers 5 bzw. 5' aufliegende, selbständige Distanzringe 18 ausgebildet sind. Auch hierdurch ist es möglich, die einzelnen Fadentrennmesser vor dem Überschleifen des Außenrandes im Kegelstumpfbereich 12 übereinander zu einem Scheibenpaket S zusammenzufassen.According to FIG. 5, there is the possibility that the spacers are designed as
Nachdem beispielsweise gemäß Fig. 3 bis 5 die einzelnen Fadentrennmesser 5 bzw. 5' zu einem Kegelscheibenpaket S zusammengefaßt sind, erfolgt das Überschleifen dieses Paketes an seinem Umfang mit einer nicht näher dargestellten Schleifscheibe bzw. Schleifwalze. Aus Fig. 4 ist der Bereich 20 erkennbar, welcher zunächst bei Bildung des Scheibenpakets S vorhanden ist und dann bei Überschleifen mit Hilfe eines nicht näher dargestellten Schleifwerkzeuges bis zur Außenseite 7, d.h. dem Zylindermantel 9, abgearbeitet wird. Damit ergibt sich auf einfache Weise die Herstellung der Schneide 8 bei einer größeren Anzahl von Fadentrennmessern 5, 5' in einem einzigen Arbeitsgang.After, for example, according to FIGS. 3 to 5, the individual thread-
Erfindungsgemäß besteht fakultativ weiterhin die Möglichkeit eines zur Schleifachse parallelen Einschleifens von V-Nuten mittels einer Schleifscheibe mit V-förmigem Schleifprofil (nicht näher dargestellt).According to the invention, there is optionally the possibility of grinding in V-grooves parallel to the grinding axis by means of a grinding wheel with a V-shaped grinding profile (not shown in more detail).
Nach der endgültigen Fertigstellung der zu dem Scheibenpaket zusammengefaßten Fadentrennmesser 5, 5' usw. wird dieses Scheibenpaket S zerlegt, so daß die einzelnen Fadentrennmesser in einsatzfähiger Form vorliegen.After the final completion of the
