Description

Die Erfindung betrifft eine Sickenmaschine für die Bearbeitung von Blech gemäss Oberbegriff des Anspruchs 1.The invention relates to a beading machine for the machining of sheet metal according to the preamble of claim 1.

Sickenmaschinen sind im Stand der Technik seit langem bekannt. Sie verformen ein Blech zwischen Arbeitswalzen durch fortschreitendes Biegen in einer Kantenrichtung. Sicken dienen insbesondere zum Versteifen von Blechen oder zum Verbinden von ineinander gesteckten Teilen. Das zu bearbeitende Blech, Rohr oder dergleichen bewegt sich beim Sicken zwischen zwei Rollen, die das Profil der Sicke tragen. Beide Rollen sind angetrieben und nehmen das Blech mit. Durch Verstellen wenigstens einer Sickenrolle eines Sickenwerkzeuges oder durch Auswechseln des Sickenwerkzeuges können unterschiedliche Sicken hergestellt werden. Im Stand der Technik ist eine Sickenmaschine bekannt, die zwei auf einer gemeinsamen Welle angeordnete Sickenwerkzeuge aufweist. Diese Sickenwerkzeuge können unterschiedlich eingestellt werden. Je nach der herzustellenden Sicke wird nun das eine oder das andere Werkzeug benutzt.Beading machines have long been known in the art. They deform a sheet between work rolls by progressively bending in an edge direction. Beads are used in particular for stiffening sheets or for joining nested parts. The metal sheet, pipe or the like to be machined moves between two rollers that carry the profile of the bead during beading. Both rollers are driven and take the sheet metal. By adjusting at least one bead of beading a beading tool or by replacing the beading tool different beads can be produced. In the prior art, a beading machine is known, which has two arranged on a common shaft beading tools. These beading tools can be set differently. Depending on the bead to be produced, one or the other tool is used.

Die US-A-4,487,048 offenbart eine Maschine zum Einarbeiten von Sicken in Büchsenrohlinge. Am Umfang einer gemeinsamen Antriebswelle sind Sickenstationen angeordnet, die zwangsgesteuert sind. Alle Sickenstationen arbeiten gleichzeitig.US-A-4,487,048 discloses a machine for incorporating beads into box blanks. At the periphery of a common drive shaft bead stations are arranged, which are positively controlled. All bead stations work simultaneously.

Der Erfindung liegt die Aufgabe zugrunde, eine Sickenmaschine der genannten Art zu schaffen, die eine noch rationellere und dennoch sichere Bearbeitung von Blech ermöglicht.The invention has for its object to provide a beading machine of the type mentioned, which allows an even more efficient and yet secure machining of sheet metal.

Die Erfindung ist bei einer gattungsgemässen Sickenmaschine gemäss Anspruch 1 gelöst. Bei der erfindungsgemässen Sickenmaschine ist an einer einzigen Arbeitsposition die Bearbeitung eines Bleches mit jedem der Sickenwerkzeuge möglich. Die Arbeitsposition muss somit nicht verlassen werden, wenn zu einem anderen Sickenwerkzeug gewechselt wird. Einerseits ist damit eine einfachere und schnellere Bearbeitung möglich und andererseits ist die Raumbeanspruchung wesentlich kleiner, da lediglich die Zugänglichkeit zu einer einzigen Arbeitsposition erforderlich ist. Die erfindungsgemässe Sickenmaschine kann deshalb beispielsweise in einer Raumecke angeordnet werden und trotzdem können drei oder mehr Sickenwerkzeuge vorhanden sein und wahlweise benutzt werden. Bei drei Sickenwerkzeugen sind diese vorzugsweise in den Ecken eines Dreieckes angeordnet. Beim Wechseln des Sickenwerkzeuges muss dann somit der Drehtisch lediglich um 120 Grad in der einen oder anderen Drehrichtung gedreht werden. Die Sickenwerkzeuge können beispielsweise Sickenrollen sein, die jedoch jeweils unterschiedlich eingestellt sind. Denkbar sind hier aber auch unterschiedliche Sickenwerkzeuge.The invention is achieved in a generic beading machine according to claim 1. In the case of the beading machine according to the invention, the machining of a metal sheet with each of the beading tools is possible at a single working position. Thus, the working position need not be left when changing to another beading tool. On the one hand, a simpler and faster processing is possible and on the other hand, the space requirement is much smaller, since only the accessibility to a single working position is required. The beading machine according to the invention can therefore be arranged, for example, in a corner of the room, and yet three or more beading tools can be present and optionally used. In three beading tools, these are preferably arranged in the corners of a triangle. When changing the beading tool then then the turntable must be rotated only by 120 degrees in one or the other direction. The beading tools may for example be bead rolls, which, however, are each set differently. Conceivable here are also different beading tools.

Jedes Sickenwerkzeug ist mit einem einzigen gemeinsamen Antrieb ein- und auskuppelbar. Damit ist ein einfacher Aufbau möglich und zudem ist jeweils lediglich das benutzte Sickenwerkzeug angetrieben, was im Hinblick auf die Arbeitssicherheit vorteilhaft ist. Beim Arbeiten stehen damit jeweils die nicht benutzten Sickenwerkzeuge still.Each beading tool can be engaged and disengaged with a single common drive. For a simple construction is possible and also only the used beading tool is driven in each case, which is advantageous in terms of safety at work. When working stand so that each unused beading tools.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung.Further advantageous features emerge from the dependent claims, the following description and the drawings.

Die Sickenmaschine 1 weist gemäss Fig. 1 ein Maschinengestell 2 auf, das an seinem unteren Ende drei Laufwerke 3 besitzt und auf einen Gebäudeboden 32 gestellt ist. Die Laufwerke 3 weisen jeweils an einem Halter 5 eine höhenverstellbare Laufrolle 4 auf. Die Sickenmaschine 1 kann auf dem Boden 32 abgestellt oder im angehobenen Zustand verfahren werden.The beading machine 1 has, according to FIG. 1, a machine frame 2 which has three drives 3 at its lower end and is placed on a building floor 32. The drives 3 each have on a holder 5 a height-adjustable roller 4. The beading machine 1 can be parked on the floor 32 or moved in the raised state.

Unterhalb einer hier lediglich teilweise gezeigten Abdeckung 33 ist am Maschinengestell 2 eine Antriebseinheit 6 angeordnet, die einen Elektromotor 7 oder einen anderen geeigneten Motor aufweist. Die Antriebsachse A dieser Antriebseinheit 6 verläuft vertikal und mittig zu einem Drehtisch 8, der gemäss Fig. 2 in gleichen Abständen zueinander und peripher drei Sickeneinheiten 9, 9' und 9'' aufweist. Der Drehtisch 8 ist um die Achse A drehbar auf dem Maschinengestell 2 gelagert. Die Fig. 2 zeigt mit dem Doppelpfeil 34 die Drehrichtungen, in denen der Drehtisch 8 um die Achse A unbegrenzt drehbar ist.Below a cover 33, which is only partially shown here, a drive unit 6, which has an electric motor 7 or another suitable motor, is arranged on the machine frame 2. The drive axis A of this drive unit 6 extends vertically and centrally to a turntable 8, which according to FIG. 2 at equal distances from one another and peripherally has three bead units 9, 9 'and 9' '. The turntable 8 is mounted rotatably about the axis A on the machine frame 2. Fig. 2 shows with the double arrow 34, the directions of rotation in which the turntable 8 is indefinitely rotatable about the axis A.

Die Antriebseinheit 6 weist gemäss Fig. 3 einen Lagerblock 17 auf, der fest mit dem Maschinengestell 2 verbunden ist und in den ein Kegelgetriebe 35 eingesetzt ist. Dieses Getriebe 35 besteht im wesentlichen aus einem Kegelrad 14, das fest mit einer vertikalen Antriebswelle 15 verbunden ist und mit drei weiteren Kegelrädern 18, die jeweils fest mit einer Kupplungswelle 16 verbunden sind und die jeweils mit dem Kegelrad 14 kämmen. In der Fig. 3 sind lediglich ein Kegelrad 18 sowie zwei Kupplungswellen 16 sichtbar. Die drei Kupplungswellen 16 sind sternförmig angeordnet und der Winkel zwischen benachbarten Kupplungswellen 16 beträgt 120 Grad. Es sind hier aber auch Ausführungen denkbar, bei welchen lediglich zwei Kupplungswellen oder mehr als drei Kupplungswellen 16 vorgesehen sind. Die Anordnung ist aber hier vorzugsweise symmetrisch und sämtliche Wellen 13 werden gemeinsam von der Welle 15 angetrieben.The drive unit 6 has, according to FIG. 3, a bearing block 17 which is fixedly connected to the machine frame 2 and in which a bevel gear 35 is inserted. This transmission 35 consists essentially of a bevel gear 14 which is fixedly connected to a vertical drive shaft 15 and three further Bevel gears 18, each of which is fixedly connected to a coupling shaft 16 and each mesh with the bevel gear 14. In Fig. 3, only one bevel gear 18 and two coupling shafts 16 are visible. The three coupling shafts 16 are arranged in a star shape and the angle between adjacent coupling shafts 16 is 120 degrees. However, embodiments are also conceivable in which only two coupling shafts or more than three coupling shafts 16 are provided. However, the arrangement is here preferably symmetrical and all shafts 13 are driven together by the shaft 15.

Die Kupplungswellen 16 überragen jeweils mit einem äusseren Ende den Lagerblock 17, wie die Fig. 3 zeigt. Auf jedem dieser Enden ist ein Kupplungsstück 36 begrenzt verschieblich gelagert. Mittels eines Kupplungshebels 19, der an seinem oberen Ende 19a an einem Bock verschwenkbar gelagert ist und an seinem unteren freien Ende einen Rastgriff 20 aufweist, kann das Kupplungsstück 36 in den Richtungen des Doppelpfeiles 38 begrenzt verstellt werden.The coupling shafts 16 project beyond the bearing block 17 with an outer end, as shown in FIG. 3. On each of these ends a coupling piece 36 is mounted slidably limited. By means of a coupling lever 19, which is pivotally mounted at its upper end 19a to a block and at its lower free end has a latching handle 20, the coupling piece 36 can be adjusted in the directions of the double arrow 38 limited.

Jede der Wellen 16 kann durch Verschwenken des Kupplungshebels 19 bei entsprechender Positionierung des Drehtisches 8 mit einer der Sickeneinheiten 9, 9' bzw. 9'' gekuppelt werden. Das Kupplungsstück 36 wird hierzu aus der in Fig. 3 gezeigten Position radial nach aussen bewegt. Hierbei greifen Kupplungsklauen 28 zwischen entsprechende Kupplungsklauen 28 eines Zahnrades 27, das fest mit einer Welle 25 einer Sickenrollen 21 verbunden ist. Das Rad 27 kämmt mit einem Zahnrad 26, das mit einer oberen Welle 24 der oberen Sickenrolle 22 verbunden ist. Die beiden Sickenrollen 21 und 22 sind in einem Lagerblock 39 gelagert, an dem eine Anschlagplatte 11 radial verstellbar gelagert ist. Die Anschlagplatte 11 greift mit einem Steg 40 in eine hier nicht gezeigte Ausnehmung des Lagerblockes 39 ein und kann in jeder Position mittels eines Klemmorgans 31 festgeklemmt werden. Die beiden Sickenrollen 21 und 22 durchgreifen die Anschlagplatte 11. Vorzugsweise ist für jede Sickeneinheit 9, 9' bzw. 9" eine solche Anschlagplatte 11 vorgesehen.Each of the shafts 16 can be coupled by pivoting the coupling lever 19 with a corresponding positioning of the turntable 8 with one of the bead units 9, 9 'and 9''. For this purpose, the coupling piece 36 is moved radially outward from the position shown in FIG. In this case, clutch claws 28 engage between corresponding clutch claws 28 of a gear 27, which is fixedly connected to a shaft 25 of a bead rollers 21. The wheel 27 meshes with a gear 26 which is connected to an upper shaft 24 of the upper bead roll 22. The two bead rolls 21 and 22 are mounted in a bearing block 39, on which a stop plate 11 is mounted radially adjustable. The stop plate 11 engages with a web 40 in a not shown here recess of the bearing block 39 and can in each position can be clamped by means of a clamping member 31. The two bead rolls 21 and 22 pass through the stop plate 11. Preferably, such a stop plate 11 is provided for each bead unit 9, 9 'or 9 ".

Die beiden Sickenrollen 21 und 22 sind wie an sich bekannt ausgebildet. Es können hier aber auch andere Sickenwerkzeuge vorgesehen sein. Ein zu bearbeitendes Blech 41 wird in an sich bekannter Weise zwischen die laufenden Sicken 21 und 22 einigeführt, wie in der Fig. 5 angedeutet ist. Das Blech 21 kann auch ein Rohr oder ein Deckel sein. Dieses wird beispielsweise gemäss Fig. 2 in der Zweiuhr-Position mit der Sickeneinheit 9 bearbeitet. Soll nun dieses Blechstück 41 oder ein anderes Blechstück mit der Sickeneinheit 9' bearbeitet werden, so wird die Sickeneinheit 9 ausgekuppelt und der Drehtisch 8 wird im Gegenuhrzeigersinn um 120 Grad gedreht. Die Sickeneinheit 9' befindet sich nun in Zweiuhr-Stellung. Sämtliche Sickeneinheiten 9, 9', bzw. 9'' sind nicht angetrieben. Nun wird die Sickeneinheit 9' mit der Antriebseinheit 6 gekuppelt und das Blech 41 kann ebenfalls in der Zweiuhr-Position mit der Sickeneinheit 9' bearbeitet werden. Wird die Sickeneinheit 9' nicht mehr benötigt, so wird diese entkuppelt und der Drehtisch 8 kann nun wahlweise im Uhrzeiger- oder Gegenuhrzeigersinn gedreht werden. Ein Drehen des Drehtisches 8 ist nur dann möglich, wenn sämtliche Sickeneinheiten 9, 9' und 9'' entkuppelt sind. Damit ist sichergestellt, dass beim Bearbeiten lediglich die Sickeneinheit 9, 9' bzw. 9'' angetrieben ist, die zur Bearbeitung eines Bleches 41 benötigt wird.The two bead rollers 21 and 22 are formed as known per se. But it can also be provided here other beading tools. A sheet 41 to be machined is brought together in a manner known per se between the running beads 21 and 22, as indicated in FIG. 5. The sheet 21 may also be a pipe or a lid. This is processed, for example, according to FIG. 2 in the two-clock position with the bead unit 9. If now this sheet metal piece 41 or another piece of sheet metal with the bead unit 9 'to be processed, the bead unit 9 is disengaged and the turntable 8 is rotated counterclockwise by 120 degrees. The bead unit 9 'is now in the two-clock position. All bead units 9, 9 'and 9' 'are not driven. Now, the bead unit 9 'is coupled to the drive unit 6 and the sheet 41 can also be machined in the two-clock position with the bead unit 9'. If the bead unit 9 'is no longer needed, it is decoupled and the turntable 8 can now be rotated either clockwise or counterclockwise. A rotation of the turntable 8 is only possible if all bead units 9, 9 'and 9' 'are decoupled. This ensures that only the bead unit 9, 9 'or 9' 'that is required for machining a metal sheet 41 is driven during machining.
