Abstract

Der Deckelstab für Kardiermaschinen, der aus einem Hohlprofil besteht und einen Garnituraufnahmeteil (1) und einen Rückenteil (2) hat, ist aus einem in die vorgegebene Profilform gezogenen rohrförmigen Materialstück hergestellt. Bei einem so hergestellten Deckelstab werden die für ein gutes Kardierergebnis erforderlichen Toleranzen zuverlässig erreicht. Auch bei der späteren Verwendung hält der Deckelstab die ihm gegebene Form mit diesen Toleranzen ein.The flat bar for carding machines, which consists of a hollow profile and has a clothing receiving part (1) and a back part (2), is made from a tubular material piece drawn into the predetermined profile shape. With a flat rod produced in this way, the tolerances required for a good carding result are reliably achieved. Even during later use, the flat rod maintains the shape given to it with these tolerances.

Description

Die Erfindung betrifft einen Deckelstab für Kardiermaschinen, der aus einem aus Blech geformten Hohlprofil besteht, das einen Garnituraufnahmeteil und einen zu diesem T-förmig angeordneten Rückenteil aufweist.The invention relates to a flat bar for carding machines, which consists of a hollow profile formed from sheet metal, which has a clothing receiving part and a back part arranged in a T-shape.

Deckelstäbe werden üblicherweise aus Gußeisen hergestellt und besitzen zur Versteifung einen T-förmigen Querschnitt. Diese Deckelstäbe sind schwer und biegen sich insbesondere bei überbreiten Kardiermaschinen unter ihrem Eigengewicht durch, wodurch die Kardierarbeit beeinträchtigt wird. Außerdem ist der Deckelantrieb bei Wanderdeckelkarden infolge des hohen Gewichtes der Deckelstäbe besonderen Belastungen unterworfen.Flat bars are usually made of cast iron and have a T-shaped cross section for stiffening. These flat bars are heavy and, especially in the case of oversized carding machines, bend under their own weight, which impairs the carding work. In addition, the flat drive for revolving flat cards is subject to special loads due to the high weight of the flat bars.

Es wurde daher schon vorgeschlagen, die Deckelstäbe als Hohlprofil aus einem Stück Blech herzustellen, um deren Gewicht zu vermindern (DE-PS 384.195). Als Hohlprofile werden solche mit T-förmigem Querschnitt oder mit dreieckförmigem Querschnitt vorgesehen, wobei die letzteren den Vorteil einer höheren Steifigkeit haben. Das Blech wird nach dem bekannten Vorschlag in die Fertiglage oder Endform gebogen und die dabei entstehende Naht beispielsweise durch Schweißen geschlossen. Diese Verfahrensweise ist kostenaufwendig und hat zudem den Nachteil, daß durch das nachfolgende Schweißen Wärmespannungen entstehen. Die Herstellung von Deckelstäben mit der erforderlichen maßgenauen Geometrie ist daher nicht gewährleistet.It has therefore already been proposed to produce the flat bars as a hollow profile from a piece of sheet metal in order to reduce their weight (DE-PS 384.195). As a hollow profile, those with a T-shaped cross section or with a triangular cross section are provided, the latter having the advantage of higher rigidity. The sheet is bent into the finished position or final shape according to the known proposal and the resulting seam is closed, for example by welding. This procedure is costly and also has the disadvantage that the subsequent welding creates thermal stresses. The manufacture of flat bars with the required precise geometry is therefore not guaranteed.

Aufgabe der vorliegenden Erfindung ist es, diese Nachteile zu vermeiden und einen Deckelstab zu schaffen, der bei geringem Gewicht einfach und mit hoher Präzision herstellbar ist.The object of the present invention is to avoid these disadvantages and to create a flat rod which can be produced easily and with high precision with low weight.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Garnituraufnahmeteil und der Rückenteil einstückig aus einem rohrförmigen Materialstück hergestellt ist, das in die vorgegebene Profilform gezogen ist.The object is achieved in that the clothing receiving part and the back part are made in one piece from a tubular material piece which is drawn into the predetermined profile shape.

Der erfindungsgemäße Deckelstab zeichnet sich dadurch aus, daß auf einfache Weise die für ein gutes Kardierergebnis notwendigen Toleranzen zuverlässig erreicht werden und der Deckelstab auch bei seiner späteren Verwendung die ihm gegebene Form mit diesen Toleranzen einhält. Dies trifft selbst für Deckelstäbe zu, deren Länge größer als die normal übliche ist.The flat bar according to the invention is characterized in that the tolerances required for a good carding result are reliably achieved in a simple manner and the flat bar also maintains the shape given to it with these tolerances when it is used later. This is true even for flat bars, the length of which is longer than the normal one.

In Weiterbildung der Erfindung wird vorgesehen, daß der Deckelstab aus einem nahtlosen Rohr hergestellt ist. Eine hohe Steifigkeit des Deckelstabes wird dadurch erreicht, daß der aus zwei Längswänden gebildete Rückenteil aus einem Rechteckteil besteht, das sich zum freien Ende hin dachförmig verjüngt. Durch diese Ausbildung des Rückenteiles kann der Deckelstab schmaler als dies bisher aus Gründen der Steifigkeit möglich war gehalten werden, so daß die Anzahl der an der Kardierarbeit beteiligten Deckelstäbe erhöht werden kann. Dies wirkt sich günstig auf das Kardierergebnis aus. Vorteilhaft werden die Höhe des Rechteckteiles und die Höhe des sich dachförmig verjüngenden Teiles so gewählt, daß sie im Verhältnis von etwa 1:1 stehen. Die Steifigkeit des Deckelstabes wird weiter dadurch verbessert, daß die Breite des Rechteckteiles etwa 1/2 bis 3/4 der Breite des Garnituraufnahmeteiles beträgt.In a further development of the invention it is provided that the flat rod is made from a seamless tube. A high rigidity of the flat rod is achieved in that the back part, which is formed from two longitudinal walls, consists of a rectangular part which tapers towards the free end in a roof shape. This design of the back part allows the flat bar to be kept narrower than was previously possible for reasons of rigidity, so that the number of flat bars involved in the carding work can be increased. This has a favorable effect on the carding result. The height of the rectangular part and the height of the tapering part are advantageously chosen so that they are in a ratio of about 1: 1. The rigidity of the flat bar is further improved in that the width of the rectangular part is about 1/2 to 3/4 of the width of the clothing receiving part.

Eine sichere Befestigung der Garnitur am Deckel mittels sogenannter "Clips" wird dadurch erreicht, daß der Garnituraufnahmeteil schräg nach innen verlaufende Halteflächen für Garnitur-Klammern aufweist, die den Garnituraufnahmeteil mit dem Rückenteil verbinden. Es hat sich gezeigt, daß es hinsichtlich der Belastung des Deckelstabes unter seinem Eigengewicht und der Kardierarbeit besonders günstig ist, wenn das Verhältnis von Höhe zu Breite des Deckelstabes 2:1 bis 4:1 beträgt.A secure attachment of the clothing to the lid by means of so-called "clips" is achieved in that the clothing receiving part has inclined inwardly extending holding surfaces for clothing clips which connect the clothing receiving part to the back part. It has been shown that it is particularly favorable with regard to the load on the flat bar under its own weight and the carding work if the ratio of height to width of the flat bar is 2: 1 to 4: 1.

Als Material für das Hohlprofil wird Stahlblech bevorzugt, da es einen hohen E-Modul hat und sein Wärmeausdehnungskoeffizient dem der Kardiermaschine entspricht. Eine weitere Verringerung des Gewichtes bei noch genügend hoher Steifigkeit des Deckelstabes in Längs- und Querrichtung wird dadurch erreicht, daß die Dicke des Bleches 1 bis 3 mm beträgt. Um eine ebene Aufnahmefläche für die Garnitur zu erhalten, ist die Unterseite des Garnituraufnahmeteiles mit einem Kunstharz beschichtet. Zur Dämpfung von Schwingungen und Geräuschen wird das Innere des Hohlprofils mit Schaumstoff ausgefüllt.Sheet steel is preferred as the material for the hollow profile, since it has a high modulus of elasticity and its coefficient of thermal expansion corresponds to that of the carding machine. A further reduction in weight with a sufficiently high rigidity of the flat bar in the longitudinal and transverse directions is achieved in that the thickness of the sheet is 1 to 3 mm. In order to obtain a flat receiving surface for the clothing, the underside of the clothing receiving part is coated with a synthetic resin. The interior of the hollow profile is filled with foam to dampen vibrations and noise.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung näher beschrieben.An embodiment of the invention will be described with reference to the drawing.

Die Zeichnung zeigt im Querschnitt einen als Hohlprofil ausgebildeten Deckelstab, der in einem Stück aus einem rohrförmigen Materialstück hergestellt ist. Das bevorzugt aus Stahlblech bestehende rohrförmige Materialstück ist im Ziehverfahren auf den dargestellten Querschnitt gebracht worden. Das dem Ziehverfahren unterworfene rohrförmige Materialstück ist zweckmäßig ein nahtloses Rohr, jedoch kann auch ein Rohr, daß eine Schweißnaht hat, verwendet werden. Der Deckelstab besteht aus einem Garnituraufnahmeteil 1 und einem sich daran anschließenden Rückenteil 2, das aus Längswänden 3 und 4, gebildet ist. Die Längswände 3 und 4 liegen parallel zu einander und bilden ein Rechteckteil 2a, das sich dann zum freien Ende hin dachförmig verjüngt. Dabei stehen vorzugsweise die Höhe des Rechteckteiles 2a und die Höhe des sich dachförmig verjüngenden Teiles 2b im Verhältnis von etwa 1:1. Eine genügend große Steifigkeit auch bei überlangen Deckelstäben ergibt sich nach bisherigen Erkenntnissen dann, wenn die Breite a des Rechteckteiles 2a etwa 1/2 bis 3/4 der Breite b des Garnituraufnahmeteiles 1 beträgt. Die Blechdicke beträgt 1 bis 3 mm, vorzugsweise 2 mm, während das Verhältnis von Höhe h zu Breite b des Deckelstabes 1 im Bereich von 2:1 bis 4:1 liegt. Die dargestellte Profilform wird bevorzugt, da sie dem Deckelstab hohe Stabilität bei geringer Breite verleiht. Zur Schwingungs- und Geräuschdämpfung wird zweckmäßig das Innere des Hohlprofils ausgeschäumt.The drawing shows in cross section a flat rod designed as a hollow profile, which is made in one piece from a tubular material piece. The tubular material piece, which is preferably made of sheet steel, has been brought to the cross section shown in the drawing process. The tubular material piece subjected to the drawing process is expediently a seamless tube, but a tube which has a weld seam can also be used. The flat bar consists of a clothing receiving part 1 and an adjoining back part 2, which is formed from longitudinal walls 3 and 4. The longitudinal walls 3 and 4 lie parallel to one another and form a rectangular part 2a, which then tapers towards the free end in a roof shape. The height of the rectangular part 2a and the height of the roof-shaped part 2b are preferably in a ratio of about 1: 1. According to previous knowledge, a sufficiently high rigidity, even with excessively long flat bars, results when the width a of the rectangular part 2a is approximately 1/2 to 3/4 of the width b of the clothing receiving part 1. The sheet thickness is 1 to 3 mm, preferably 2 mm, while the ratio of height h to width b of the flat bar 1 is in the range from 2: 1 to 4: 1. The profile shape shown is preferred because it gives the flat bar high stability with a small width. The interior of the hollow profile is expediently foamed in order to dampen vibrations and noise.

Um eine absolut ebene Fläche für die Auflage der Garnitur zu erhalten, wird die Unterseite 5 des Garnituraufnahmeteiles 1 mit einem Kunstharz beschichtet. Die Befestigung der Garnitur am Garnituraufnahmeteil 1 kann in beliebiger Weise erfolgen, beispielsweise mittels der üblichen Befestigungsklammern (Clips) oder einer Schraubverbindung. Zum sicheren Festklemmen der Garnitur mit Klammern weist das Garnituraufnahmeteil 1 schräg nach innen verlaufende Halteflächen 6 und 7 für die Klammern auf. Diese Halteflächen verbinden den Garnituraufnahmeteil 1 mit dem Rückenteil 2.In order to obtain an absolutely flat surface for supporting the clothing, the underside 5 of the clothing receiving part 1 is coated with a synthetic resin. The clothing can be fastened to the clothing receiving part 1 in any manner, for example by means of the usual fastening clips (clips) or a screw connection. In order to securely clamp the clothing with clips, the clothing receiving part 1 has holding surfaces 6 and 7 for the clips which run obliquely inwards. These holding surfaces connect the clothing receiving part 1 to the back part 2.

Der erfindungsgemäße Deckelstab ist sowohl als Wanderdeckel als auch als ortfestes Kardierelement verwendbar. Beim Einsatz als Wanderdeckel gewährleistet er einen ruhigen Lauf.The flat bar according to the invention can be used both as a revolving lid and as a stationary carding element. When used as a revolving lid, it ensures smooth running.
