Abstract

A jointing machine for the folding of seams in manufacturing of seamed metal sheets made of segments of metal sheets is disclosed, wherein the machine includes a locking wheel pivotably positioned in a recess of a resiliently disposed locking wheel carriage. The seam during formation is supported from below by a support roller, and is held from the sides by an adjustment roller together with the locking wheel. The locking wheel carriage is positioned diagonally relative to the surface of the support roller, which enables the machine to manufacture folded seams in very small metal sheet segments, and to utilize thick or hard metal sheets. The particular arrangement of the jointing machine of the present invention which respect to the locking wheel carriage diagonal positioning enables the locking wheel to penetrate even restricted spaces, and the folding of the seam can be accomplished in several steps wherein the use of the locking wheel carriage ensures the transmission to the seam of sufficient force to form a strong folded joint.

Description

Die vorliegende Erfindung bezieht sich auf eine Falzschliessmaschine zum Schliessen von Falzverbindungen bei der Herstellung von aus Bogensegmenten bestehenden Bogen aus Blech, gemäß Oberbegriff von Anspruch 1.The present invention relates to a folding closing machine for closing fold connections in the production of sheets consisting of sheet segments from sheet metal, according to the preamble of claim 1.

Falzschliessmaschinen dieser Art sind schon bekannt. So z.B. in der US-A-4 006 520, insbesondere in den Figuren 1 und 2 und in den Spalten 3 und 4, ist eine Falzschliessmaschine der obenerwähnten Art beschrieben und dargestellt. Bei dieser Lösung ist ein Schliessrad in einem Schliessradschlitten drehbar gelagert, wobei das Schliessrad mit der Stützrolle einen spitzen Winkel einschliesst. Die Wellen des Schliessrades und der Stützrolle sind jedoch nur einseitig gelagert. Diese Ausführungsform weist auch federnde Bestandteile auf und der das Schliessrad tragende Teil kann mechanisch geschoben werden. Diese Lösung hat jedoch den Nachteil, dass sie sich nur für Falzverbindungen von Bögen eignet, die ausreichend gross sind, weil auf die Falzflächen zwei Räder drücken müssen, die in verhältnismässig grossen Supporten drehbar gelagert sind.Folding closing machines of this type are already known. So e.g. US-A-4 006 520, in particular in FIGS. 1 and 2 and in columns 3 and 4, describes and illustrates a seaming machine of the type mentioned above. In this solution, a closing wheel is rotatably mounted in a closing wheel carriage, the closing wheel including the support roller forming an acute angle. The shafts of the locking wheel and the support roller are only supported on one side. This embodiment also has resilient components and the part carrying the locking wheel can be pushed mechanically. However, this solution has the disadvantage that it is only suitable for fold connections of sheets which are sufficiently large because two wheels have to press on the fold surfaces and are rotatably supported in relatively large supports.

Der Erfindung liegt die Aufgabe zugrunde, eine Falzschliessmaschine der eingangs genannten Art zu schaffen, mit der man auch kleine Bögen oder dicke Bleche verarbeiten kann. Die Falzschliessmaschine soll also auch mit einem sehr hohen Druck arbeiten können.The invention has for its object to provide a seaming machine of the type mentioned, with which one can also process small sheets or thick sheets. The seaming machine should also be able to work with a very high pressure.

Die vorgenannte Aufgabe wird erfindungsgemäss dadurch gelöst, dass der Schliessradschlitten im Support mit einer mittels Druckfedern beanspruchten Führungsplatte gehalten ist und dass der Schliessradschlitten zu seinem Zustellen mit einem hydraulischen Zylinder mechanisch verbunden ist.According to the invention, the above-mentioned object is achieved in that the closing wheel slide is held in support with a guide plate which is loaded by means of compression springs, and in that the closing wheel slide is mechanically connected to a hydraulic cylinder for its infeed.

Der Vorteil der Erfindung besteht darin, dass das Schliessrad auch in einem begrenzten Raum tätig sein kann und dass sie durch worteilhafte Schlittenführung einen ausreichenden Druck auf das zu bearbeitende Blech ausüben kann, so dass auch Bögen aus verhältnismässig dickem Blech hergestellt werden können. Diese Ausbildungsform ermöglicht eine einfache und ausreichend massive Montage des Schliessradschlittens. Somit kann mit ausreichender Kraft das im Schliessradschlitten gelagerte Schliessrad zugestellt werden, wodurch der Falz geschlossen wird. Der Zylinder kann durch entsprechende Steuerung in einem oder mehreren Schritten zugestellt werden. Dies erlaubt das Umlegen von dickem Blech.The advantage of the invention is that the closing wheel can also operate in a limited space and that it can exert sufficient pressure on the sheet metal to be machined by means of advantageous carriage guidance, so that sheets can also be produced from relatively thick sheet metal. This form of training enables a simple and sufficiently massive assembly of the closing wheel slide. The closing wheel mounted in the closing wheel slide can thus be delivered with sufficient force, whereby the fold is closed. The cylinder can be advanced in one or more steps by appropriate control. This allows the folding of thick sheet metal.

Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.Advantageous developments of the invention are described in the dependent claims.

Es ist zweckmässig, wenn der Schliessradschlitten in einem Support federnd gelagert ist. Diese Lösung erleichtert das Schliessen von Falzverbindungen auch bei einer Verdickung des Bleches, die z.B. bei der Bearbeitung der Naht entsteht. In diesem Fall kann der Schliessradschlitten nach oben ausweichen.It is expedient if the closing wheel slide is spring-mounted in a support. This solution makes it easier to close seam connections even if the sheet thickens, e.g. arises when processing the seam. In this case the closing wheel slide can move upwards.

Es ist besonders vorteilhaft, wenn der spitze Winkel zwischen dem Schliessradschlitten und der Abstützfläche der Stützrolle 20° bis 30° beträgt. Dieser Winkel ermöglicht sowohl das Eindringen des Schliessrades bei der Herstellung von kleinen Bögen als auch das Erreichen eines notwendigen Druckes auf die zu bearbeitende Stelle.It is particularly advantageous if the acute angle between the closing wheel slide and the support surface of the support roller is 20 ° to 30 °. This angle allows both the penetration of the closing wheel when producing small sheets and the achievement of the necessary pressure on the area to be processed.

Es ist zweckmässig, wenn der hydraulische Zylinder mit einer Einstellmutter zum Einstellen des maximalen Hubes versehen ist. Somit kann man die Arbeitsweise den vorbestimmten Abmessungen des Falzes anpassen.It is useful if the hydraulic cylinder is provided with an adjusting nut for adjusting the maximum stroke. This allows you to adapt the working method to the predetermined dimensions of the fold.

Bei einer vorteilhaften Ausbildungsform sind der den Schliessradschlitten tragende Support auf einem Zustellschlitten befestigt und die Stützrolle in diesem Zustellschlitten drehbar gelagert. Diese Konstruktion erleichtert sowohl das Zustellen als auch das Ausfahren des Bogens.In an advantageous embodiment, the support carrying the closing wheel slide is fastened on a feed slide and the support roller is rotatably mounted in this feed slide. This construction facilitates both the delivery and the extension of the sheet.

Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand schematischer Zeichnungen näher erläutert.An embodiment of the invention is explained below with reference to schematic drawings.

Es zeigt:

Ein Werkzeugteil A gemäss Figur 1 enthält eine nur teilweise gezeichnete Zustellrolle 1, eine Stützrolle 2 mit feststehender Rotationsachse und ein Schliessrad 6, das in einer länglichen Ausnehmung eines Schliessradschlittens 5 drehbar gelagert ist. Der Schliessradschlitten 5 ist werschiebbar in einer Ausnehmung eines Supports 4 gelagert. Von oben ist der Schliessradschlitten mittels einer Führungsplatte 9 gehalten. Diese Führungsplatte 9 ist mit dem Support 4 mit Schrauben 8 befestigt, wobei die Köpfe dieser Schrauben 8 mit Druckfedern 7 versehen sind, so dass die Führungsplatte 9 den Schliessradschlitten 5 in die Ausnehmung des Supports 4 mit einer ausreichenden Kraft drückt. In diesem Beispiel wurden als Druckfedern 7 Tellerfedern verwendet. Der Support 4 ist auf einem Zustellschlitten 3 befestigt, wobei in diesem Zustellschlitten 3 auch die Stützrolle 2 drehbar gelagert ist. Der Schliessradschlitten 5 ist mit einem hydraulischen Zylinder 10 mechanisch verbunden. Der maximale Hub des Zylinders 10 ist mit B bezeichnet und durch eine Einstellmutter 11 einstellbar. Im linken Teil der Figur 1 ist ein Teil einiger Bogensegmente 12 gezeigt, wobei der Falz dieser Bogensegmente mit 12' bezeichnet ist. Die Länge der bearbeiteten Teile der Bogensegmente 12 ist mit C benannt: Diese Figur 1 zeigt eine Stellung des Schliessrades 6, in der ein Falz schon hergestellt ist. Wie aus der Figur 1 gut sichtbar ist, ist der Falz 12' auf der Abstützfläche 2' der Stützrolle 2 abgestützt, von links mit der Zustellrolle 1 gehalten und von oben mit dem Schliessrad 6 gepresst.A tool part A according to FIG. 1 contains an only partially drawn feed roller 1, a support roller 2 with a fixed axis of rotation and a closing wheel 6 which is rotatably mounted in an elongated recess of a closing wheel slide 5. The closing wheel slide 5 is slidably mounted in a recess of a support 4. The closing wheel slide is held from above by means of a guide plate 9. This guide plate 9 is fastened to the support 4 with screws 8, the heads of these screws 8 being provided with compression springs 7, so that the guide plate 9 presses the closing wheel slide 5 into the recess of the support 4 with a sufficient force. In this example, 7 disc springs were used as compression springs. The support 4 is fastened on a feed slide 3, the support roller 2 also being rotatably mounted in this feed slide 3. The closing wheel slide 5 is mechanically connected to a hydraulic cylinder 10. The maximum stroke of the cylinder 10 is designated B and is adjustable by an adjusting nut 11.

Auch in der Figur 3 sieht man vereinfacht gezeichnet die Stützrolle 2, den Zustellschlitten 3, die Zustellrolle 1 und die nur symbolisch dargestellten Bogensegmente 12. Die Grundmaschine D, die den Werkzeugteil A trägt, ist aus verschiedenen Lösungen an sich bekannt und darum nur vereinfacht gezeichnet und beschrieben. In einem Maschinenständer 13 ist ein Hydraulikaggregat 14 angeordnet, das zwei Hydromotoren 15 für den Antrieb der beweglichen Teile speist. Ein Zylinder 16 ist für die Bewegung des schon in der Figur 1 gezeigten Zustellschlittens 3 bestimmt. Eine Halterung 17 dient zum Abstützen aus den Bogensegmenten 12 bestehenden Bogens.Figure 3 shows the overall arrangement of the seaming machine with the previously described tool part A according to Figure 1. The same parts are given the same designations in all figures. Also shown in FIG. 3 is the support roller 2, the feed carriage 3, the feed roller 1 and the arc segments 12, which are only symbolically represented.
