Description

Die Erfindung betrifft einen Vorformkopf für Seile und Kabelarmierungen mit drei auf einer Achse in einer Richtung mit zunehmenden Durchmessern angeordneten Vorformscheiben, wovon die kleinste Vorformscheibe fest und die anderen Vorformscheiben verschiebbar auf der Achse angeordnet sind.The invention relates to a preform head for ropes and cable reinforcements with three preform disks arranged on an axis in one direction with increasing diameters, of which the smallest preform disk is fixed and the other preform disks are arranged displaceably on the axis.

Ein derartiger Vorformkopf ist aus der US-PS 2 476 180 oder DE-A-1 510 164 bekannt. Um Seile oder Kabelarmierungen mit unterschiedlichen Schlaglängen herstellen zu können, muß der Abstand zwischen den Vorformscheiben einstellbar sein, wobei die Abstände zwischen den benachbarten Vorformscheiben immer gleich groß sein müssen. Bei den bekannten Vorformköpfen erfolgt die Verstellung von Hand, wobei diese wegen des notwendigen Spiels nicht immer zentrisch zueinander erfolgt, so daß auch aus diesem Grunde erheblicher Meß- und Einstellaufwand betrieben werden muß.Such a preform head is known from US Pat. No. 2,476,180 or DE-A-1,510,164. In order to be able to manufacture ropes or cable reinforcements with different lay lengths, the distance between the preforming disks must be adjustable, the distances between the adjacent preforming disks always having to be the same size. In the known preforming heads, the adjustment is carried out by hand, although this is not always centered on one another because of the necessary play, so that considerable measuring and adjustment effort must also be made for this reason.

Aufgabe der Erfindung ist es, einen Vorformkopf der eingangs genannten Art dahingehend zu verbessern, daß die Verstellung der Vorformscheiben auf einfache, leichte und schnelle Weise und dennoch präzise vorzunehmen erlaubt.The object of the invention is to improve a preform head of the type mentioned in such a way that the adjustment of the preform disks allows to be carried out in a simple, easy and fast manner and yet precisely.

Diese Aufgabe wird durch einen Vorformkopf mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a preform head with the features of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous embodiments of the invention can be found in the subclaims.

Nachstehend wird die Erfindung anhand eines Ausführungsbeispiels unter Bezug auf schematische Zeichnungen näher erläutert. Es zeigt:

The invention is explained in more detail below using an exemplary embodiment with reference to schematic drawings. It shows:
Fig. 1
a preform head in partial section;
Fig. 2
the adjusting device for adjusting the movable preform disks;
Fig. 3
a section along line III-III in Fig. 2;

Der in Fig. 1 dargestellte Vorformkopf weist ein Rohr 1 und drei Vorformscheiben mit unterschiedlichen Durchmessern auf, eine kleine vordere Vorformscheibe 2, eine mittlere Vorformscheibe 3 und eine große hintere Vorformscheibe 4. Die kleine Vorformscheibe 2 ist am vorderen Ende des Rohrs 1 starr befestigt. Die mittlere Vorformscheibe 3 weist einen inneren Ringflansch 5 auf, auf dem zur Feineinstellung - auf bekannte Weise - die mittlere Vorformscheibe 3 verstellbar angeordnet ist. Der Ringflansch 5 ist starr mit einem Ende mit einer Zahnstange 6 fest verbunden, die in einer Paßnut 7 in der Wand des Rohres 1 gleitbar angeordnet ist.The preform head shown in FIG. 1 has a tube 1 and three preform disks with different diameters, a small front preform disk 2, a medium preform disk 3 and a large rear preform disk 4. The small preform disk 2 is rigidly attached to the front end of the tube 1. The middle preform disk 3 has an inner ring flange 5, on which the middle preform disk 3 is adjustably arranged in a known manner for fine adjustment. The ring flange 5 is rigid with one end firmly connected to a rack 6 which is slidably disposed in a fitting groove 7 in the wall of the tube 1.

Parallel zur Paßnut 7, um einen Winkel von 90° versetzt, ist im Rohr 1 eingetieft eine Zahnstange 8 unbeweglich angeordnet. Die Zahnstange 8 kann aus der Rohrwandung herausgearbeitet sein oder als fertige Zahnstange in einer Nut oder direkt am Rohr 1 befestigt sein. Die größte Vorformscheibe 4 ist beweglich auf dem Rohr 1 angeordnet und ist an ihrer von der mittleren Vorformscheibe 3 wegweisenden hinteren Seite mit einem Gehäuse 9 fest verbunden. Innerhalb des Gehäuses 9 ist auf einer Achse 10 ein Zahnrad 11 drehbar gelagert, das mit der festen Zahnstange 8 in Eingriff steht. Das Zahnrad 11 kämmt mit einer ebenfalls im Gehäuse 9 gelagerten Schnecke 12, deren Achse 13 eine aus dem Gehäuse 9 herausragenden Fortsatz 14 aufweist. Der Fortsatz 14 kann einen mehrkantigen Querschnitt aufweisen und mit einem Werkzeug, z. B. einem Schraubenschlüssel mit entsprechendem Querschnitt gedreht werden. Durch eine Drehung des Fortsatzes 14 und damit der Achse 13 mit der Schnecke 12 wird das mit der festen Zahnstange 8 in Eingriff stehende Zahnrad 11 bewegt und verschiebt dadurch die Vorformscheiben 2 und 3 mit dem Rohr 1 durch die große Vorformscheibe 4 entsprechend der gewählten Drehrichtung nach vorne oder nach hinten.Parallel to the fitting groove 7, offset by an angle of 90 °, a rack 8 is immovably arranged in the tube 1. The rack 8 can be worked out of the tube wall or can be attached as a finished rack in a groove or directly to the tube 1. The largest preform disc 4 is movably arranged on the tube 1 and is fixedly connected to a housing 9 on its rear side pointing away from the middle preform disc 3. Within the housing 9, a gear 11 is rotatably mounted on an axis 10, which meshes with the fixed rack 8. The gearwheel 11 meshes with a worm 12, which is also mounted in the housing 9 and whose axis 13 has an extension 14 protruding from the housing 9. The extension 14 may have a polygonal cross-section and with a tool such. B. a wrench with the appropriate cross section. By rotating the extension 14 and thus the axis 13 with the worm 12, the gear 11 engaged with the fixed rack 8 is moved and thereby displaces the preform disks 2 and 3 with the tube 1 through the large preform disk 4 in accordance with the selected direction of rotation front or back.

Im Gehäuse 9 ist auch ein Zahnrad 15 auf einer Achse 16 gelagert, deren Zentralachse mit der Zentralachse des Zahnrades 11 und der Achse 10 einen Winkel von 90° einschließt. Beide Zentralachsen liegen in einer sich senkrecht zur Rohrlängserstreckung liegenden Ebene. Das Zahnrad 15 kämmt mit der beweglichen Zahnstange 6. Durch eine Drehbewegung des Zahnrades 15 wird die beweglich in der Paßnut 7 angeordnete Zahnstange 6 entsprechend der jeweiligen Drehrichtung nach vorn oder nach hinten bewegt und nimmt so die mit der Zahnstange 6 fest verbundene mittlere Vorformscheibe 3 mit.In the housing 9, a gear 15 is also mounted on an axis 16, the central axis of which forms an angle of 90 ° with the central axis of the gear 11 and the axis 10. Both central axes lie in a plane perpendicular to the pipe length. The toothed wheel 15 meshes with the movable toothed rack 6. By rotating the toothed wheel 15, the toothed rack 6, which is movably arranged in the fitting groove 7, is moved forwards or backwards in accordance with the respective direction of rotation and thus takes the middle preform disk 3, which is firmly connected to the toothed rack 6 .

Die Achse 16 des Zahnrades 15 als auch die Achse 10 des Zahnrades 11 tragen Kegelräder 17 bzw. 18, die miteinander kämmen. Das Kegelrad 18, das auf der Achse 16 angeordnet ist, deren Zahnrad 15 mit der beweglichen Zahnstange 6 in Eingriff steht, weist eine doppelt so große Anzahl an Zähnen auf, wie das Kegelrad 17, das auf der Achse 10 des Zahnrades 11 angeordnet ist, das mit der starren Zahnstange 8 kämmt.The axis 16 of the gear 15 and the axis 10 of the gear 11 carry bevel gears 17 and 18, which mesh with each other. The bevel gear 18, which is arranged on the axis 16, the gear 15 of which meshes with the movable rack 6, has twice as many teeth as the bevel gear 17, which is arranged on the axis 10 of the gear 11, that combs with the rigid rack 8.

Durch die kinematische Verbindung über die Kegelräder 17, 18 wird bei einer Drehbewegung mittels eines Antriebs, der am Fortsatz 14 angreift, gleichzeitig die mittlere Vorformscheibe 3 und die kleine Vorformscheibe 2 in einer Richtung verschoben, und zwar durch das Übersetzungsverhältnis der Kegelräder von 1:2, die kleine Vorformscheibe 2 mit doppelter Geschwindigkeit wie die mittlere Vorformscheibe 3, so daß, wenn in einer Ausgangsstellung der Abstand A zwischen der kleinsten Scheibe 2 und der mittleren Scheibe 3 gleich groß ist wie der Abstand B zwischen der mittleren Vorformscheibe 3 und der größeren Vorformscheibe 4, jede Verstellung synchron unter präziser Einhaltung der Abstände A = B auf einfache Weise nur durch Drehen des Fortsatzes 14 möglich ist. Am Fortsatz 14 kann auch ein Motor (nicht dargestellt) angreifen, so daß auch eine Fernbedienung möglich ist.As a result of the kinematic connection via the bevel gears 17, 18, the middle preform disk 3 and the small preform disk 2 are simultaneously displaced in one direction during a rotary movement by means of a drive which engages the extension 14, specifically by the ratio of the bevel gears of 1: 2 , the small preform disk 2 at twice the speed of the middle preform disk 3, so that if in a starting position the distance A between the smallest disk 2 and the middle disk 3 is the same as the distance B between the middle preform disk 3 and the larger preform disk 4, each adjustment synchronously with precise observance of the distances A = B is possible in a simple manner only by rotating the extension 14. A motor (not shown) can also engage on the extension 14, so that remote control is also possible.
