Die Erfindung betrifft eine Vorrichtung zum Herstellen von Hohlprofilen nach dem Oberbegriff von Anspruch 1 und ein Verfahren zum Herstellen von Hohlprofilen nach dem Oberbegriff von Anspruch 9. The invention relates to a device for producing hollow sections according to the preamble of claim 1 and a method for producing hollow sections according to the preamble of claim 9.
Bekannt sind Vorrichtungen zum Herstellen von Hohlprofilen, bei denen in mehreren unabhängig voneinander stattfinden Schritten beispielsweise zum Beladen, Verformen und Entladen Hohlprofile hergestellt werden. Nachteilig ist es, dass bei diesen bekannten Verfahren insbesondere Unterbrechungen oder ein zwischenzeitliches Absetzen der Platine erfolgt, so dass jeweils wieder ein Einrichten erfolgen muss und eine genaue Ausrichtung der Platinen. Devices are known for producing hollow profiles in which hollow sections are produced in a plurality of steps taken independently of one another, for example for loading, deformation and unloading. The disadvantage is that in these known methods in particular interruptions or an intermediate settling of the board takes place, so that in each case an adjustment must be made and an accurate alignment of the boards.
Aufgabe der vorliegenden Erfindung ist es, eine schnelle und sichere Vorrichtung zum Verformen bereitzustellen. The object of the present invention is to provide a quick and secure deforming device.
Die Aufgabe wird gelöst durch eine Vorrichtung zum Herstellen von Hohlprofilen, insbesondere Rohren, umfassend eine Biegeeinrichtung zum Biegen einer Platine, insbesondere eine Schweißeinrichtung zum Verschließen einer Längsnaht des Hohlpro- fils, insbesondere des Rohres, eine Transportvorrichtung zum Laden einer Platine, eine Transportvorrichtung zum Entladen des Hohlprofils, ein Stempelwerkzeug und zumindest ein Matrizenwerkzeug zum Formen des Hohlprofils, wobei das Stempelwerkzeug und das Matrizenwerkzeug in Axialrichtung längsverschieblich vorgesehen sind. The object is achieved by an apparatus for producing hollow profiles, in particular tubes, comprising a bending device for bending a circuit board, in particular a welding device for closing a longitudinal seam of the hollow profile, in particular of the tube, a transport device for loading a circuit board, a transport device for unloading the hollow profile, a punch tool and at least one die tool for forming the hollow profile, wherein the punch tool and the die tool are provided longitudinally displaceable in the axial direction.
Bestätigungskopie| Hierdurch kann ein U-O-Biegen eines Hohlprofils in einer einzigen sehr kompakten, schmalen Presse erfolgen. Ein Werkzeugwechsel muss insbesondere nur im Obermatrizenwerkzeug erfolgen, wodurch Kollisionen und komplexe Bewegungsabläufe vermieden werden. Vorteilhaft ist es, wenn das Stempelwerkzeug und ein Obermatrizenwerkzeug zur Formung der Gegenrundung des Hohlprofils in Axialrichtung hintereinander angeordnet sind und zusammen in Axialrichtung längsverschieblich vorgesehen sind. Confirmation copy | This allows a UO bending of a hollow profile in a single very compact, narrow press done. In particular, a tool change must only take place in the upper die tool, which avoids collisions and complex movement sequences. It is advantageous if the punch tool and an upper die tool for forming the counter-rounding of the hollow profile in the axial direction are arranged one behind the other and are provided longitudinally displaceable in the axial direction.
Vorteilhaft ist es, wenn ein Seitenschieber, insbesondere jeweils ein Seitenschieber auf gegenüberliegenden Seiten der Vorrichtung, zum radialen Zubiegen des Hohlprofils vorgesehen sind. It is advantageous if a side slide, in particular a respective side slide on opposite sides of the device, are provided for the radial addition of the hollow profile.
Vorteilhaft ist es, wenn das Stempelwerkzeug zugleich als Transportvorrichtung zum Entladen des Hohlprofils einzusetzen ist, insbesondere indem mit einem Ende des Stempelwerkzeugs ein Herausschieben des Hohiprofils vorzunehmen ist und/oder das geformte Hohlprofil mittels einer Haltevorrichtung in einem Bereich des Obermatrizenwerkzeugs gehalten ist und damit heraustransportierbar ist. It is advantageous if the punch tool is at the same time to be used as a transport device for unloading the hollow profile, in particular by pushing out the hoof profile with one end of the punch tool and / or the shaped hollow profile is held in a region of the upper die tool by means of a holding device and can thus be transported out ,
Vorteilhaft ist es, wenn die Transportvorrichtung zum Laden einer Platine Sauger aufweist, die insbesondere seitlich des Stempelwerkzeugs angeordnet sind. It is advantageous if the transport device for loading a circuit board suction device, which are arranged in particular laterally of the stamping tool.
Vorteilhaft ist es, wenn ein T-Einsatz im Bereich zusammentreffender Enden der Seiten des Hohlprofils, insbesondere des Rohres, vorgesehen sind, der einen Abstandsschlitz zwischen den Enden freihält. It is advantageous if a T-insert in the region coinciding ends of the sides of the hollow profile, in particular of the tube, are provided, which keeps a clearance slot between the ends.
Vorteilhaft ist es, wenn der T-Einsatz als Haltevorrichtung für das fertig geformte Hohlprofil einsetzbar ist. It is advantageous if the T-insert can be used as a holding device for the finished shaped hollow profile.
Vorteilhaft ist es, wenn zur vollständigen Schließung der Biegevorrichtung die Sei- tenschieber aus einem Werkzeugschließbereich herausfahrbar sind. Die Aufgabe wird ebenfalls gelöst durch ein Verfahren zum Herstellen von Hohlprofilen, insbesondere Rohren, wobei mit einer Vorrichtung zum Herstellen von Hohlprofilen, insbesondere nach einem der Ansprüche 1 bis 8, eine Platine in eine Biegeeinrichtung für ein Hohlprofil geladen wird, mit einem Stempelwerkzeug in einem Untermatrizenwerkzeug gebogen wird , das Stempelwerkzeug in Axialrichtung derart aus einem Biegebereich heraus verschoben wird, dass ein damit in Axialrichtung gekoppeltes Obermatrizenwerkzeug oberhalb des Untermatrizenwerkzeugs angeordnet wird und damit die weitere Verformung durchgeführt wird. It is advantageous if, for complete closure of the bending device, the side slides can be moved out of a tool closing area. The object is also achieved by a method for producing hollow profiles, in particular tubes, wherein a device for producing hollow profiles, in particular according to one of claims 1 to 8, a board is loaded into a bending device for a hollow profile, with a punch tool in one Submatrix tool is bent, the punch tool in the axial direction is moved out of a bending region such that an axially coupled thereto upper die tool above the Untermatrizenwerkzeugs is arranged and thus the further deformation is performed.
Vorteilhaft ist es, wenn das so durchgeführt wird, dass in Seitenbereichen des Stem- pelwerkzeugs eine Transportvorrichtung zum Laden einer Platine eine Platine aufgreift und mittels Rückfahren des Stempelwerkzeugs in Axialrichtung die Biegevorrichtung im Bereich des Untermatrjzenwerkzeugs belädt, wobei insbesondere ein Ende des Stempelwerkzeugs und/oder eine im Bereich des Obermatrizenwerkzeugs angeordnete Haltevorrichtung das geformte Hohlprofil aus dem Untermatrizenwerk- zeug entfernt. It is advantageous if this is carried out in such a way that in lateral areas of the stamping tool a transport device for loading a board picks up a board and loads the bending device in the area of the lower die tool by moving the stamping tool back in the axial direction, wherein in particular one end of the stamping tool and / or a holding device arranged in the area of the upper die tool removes the shaped hollow profile from the lower die tool.

Hierzu sind die Matrizenwerkzeughalter oben und unten vorgesehen, wobei diese insbesondere je nach benötigtem Durchmesser wechselbar sind. Die Biegeeinrichtung 3 weist hierfür eine Presse mit vorbestimmter Druckkraft zum O-Formen eines Rohres 5 aus der Platine 2 auf. Mit dem erfindungsgemäßen Verfahren zur Herstellung von Rohren können insbesondere längsnahtgeschweißte Rohre vorbestimmter Länge hergestellt werden, insbesondere bis etwa 2.500 mm. Fig. 2 zeigt eine Vorrichtung zum Herstellen von Hohlprofilen, insbesondere Rohren 5, mit Stempelwerkzeug 6. Mit dem Stempelwerkzeug 6, insbesondere einem Biegestempel, wird über runde Enden 14 von vorzugsweise an beiden Seiten 1 1 angeordneten Seitenschiebern 10 die Platine 2 in das Untermatrizenwerkzeug 12, insbesondere eine Biegematrize, gedrückt, so dass eine U-Form entsteht. 1 shows a device 1 for producing hollow profiles, in particular tubes, with an inserted circuit board 2. A bending device 3 has a stamping tool 6 which can be exchanged for different diameters. Correspondingly, the bending device 3 has a sub-die tool 12 into which the stamping tool 6 is pressed. In addition to the lower die tool 12, the bending device also has an upper die tool 9, through which, after the lower part of the blank 2 has been formed, the upper part of the blank is also formed into the tube 5. For this purpose, the Matrizenwerkzeughalter are provided at the top and bottom, which in particular are changeable depending on the required diameter. For this purpose, the bending device 3 has a press with a predetermined pressure force for O-forming a tube 5 from the circuit board 2. With the method according to the invention for producing pipes, in particular longitudinally welded pipes of predetermined length can be produced, in particular up to about 2,500 mm.

Fig. 3 zeigt eine Vorrichtung zum Herstellen von Hohlprofilen, insbesondere Rohren 5, mit Stempelwerkzeug 6. Das Stempelwerkzeug 6 lüftet und die Seitenschieber 10 biegen die bereits zu einem U verformte Platine 2 zu einem U. mit nach innen geneigten Seiten 13 leicht zusammen. Fig. 3 shows an apparatus for producing hollow sections, in particular tubes 5, with punch tool 6. The plunger tool 6 airs and the side gate 10 bend the already deformed to a U board 2 to a U. with inwardly inclined sides 13 together.
Fig. 4 zeigt eine Vorrichtung zum Herstellen von Hohlprofilen, insbesondere Rohren 5, mit herausgezogenem Stempelwerkzeug 6. Das Stempelwerkzeug 6 geht in Position, damit Werkzeugoberteile, insbesondere das Stempelwerkzeug 6 und ein Obermatrizenwerkzeug 9 gekoppelt, in Axialrichtung 8 gewechselt werden können. 4 shows an apparatus for producing hollow profiles, in particular tubes 5, with the punch tool 6 pulled out. The punch tool 6 is in position so that tool tops, in particular the punch tool 6 and an upper die tool 9 coupled, can be changed in the axial direction 8.
Fig. 5 zeigt eine Vorrichtung zum Herstellen von Hohlprofilen, insbesondere Rohren 5, mit verschobenem Stempelwerkzeug 6. Das Stempelwerkzeug 6 und das Obermatrizenwerkzeug 9 wechseln ihre Position in Axialrichtung 8, sobald der Pressenhub eine vorbestimmte Höhe erreicht hat. Diese Vorgehensweise kann auch als Aus- schiebezwischenpuffer genutzt werden. Hierdurch kann ein U-O-Biegen eines Rohr- Rohlings in einer einzigen sehr kompakten, schmalen Presse erfolgen. Ein Werk-' zeugwechsel muss insbesondere nur im Obermatrizenwerkzeug 9 erfolgen, wodurch Kollisionen und komplexe Bewegungsabläufe vermieden werden. Fig. 6 zeigt eine Vorrichtung zum Herstellen von Hohlprofilen, insbesondere Rohren 5, mit Formung in Obermatrizenwerkzeug 9. Die Seitenschieber 10 werden zum Zubiegen des Rohrrohlings zusammengeschoben. Fig. 5 shows an apparatus for producing hollow sections, in particular tubes 5, with displaced punch tool 6. The punch tool 6 and the upper die tool 9 change their position in the axial direction 8 as soon as the press stroke has reached a predetermined height. This procedure can also be used as a push-out buffer. This allows a UO bending of a tube blank in a single very compact, narrow press done. Carried a tool 'tool change must in particular only in Obermatrizenwerkzeug 9 whereby collisions and complex movements are avoided. 6 shows a device for producing hollow profiles, in particular tubes 5, with shaping in upper die tool 9.

In dem vorliegenden Schritt des Verfahrens erfolgt die O-Ausformung des Rohres 5. Für Rohre mit einem Abstandsschlitz, nicht dargestellt, kann vorteilhaft ein T-Einsatz verwendet werden, der zudem den Schlitz in Position hält und verhindert, dass er sich eventuell spiralig verformt. Bei Rohren 5 ohne Schlitz erfolgt eine reine O-Aus- formung der Platine 2 zwischen den beiden Matrizen. Das Rohr 5 formt sich an der Kontur entlang aus, unter Umständen erfolgt, - falls die Platinenlänge größer als der theoretische Rohrumfang ist, eine Stauchung des Materials, was für die Qualität des Rohres in Bezug auf Rundheit und Festigkeitssteigerung vorteilhaft ist. In letzterem Fall kann das Rohr 5 mit Klammern oder ähnlichen Hilfsmitteln in der Halbschale des Obermatrizenwerkzeugs 9 gehalten werden  In the present step of the method, the O-formation of the tube 5 takes place. For tubes with a spacer slot, not shown, a T-insert can advantageously be used, which also holds the slot in position and prevents it from possibly becoming spirally deformed. In the case of tubes 5 without slits, a pure O-shaping of the plate 2 takes place between the two matrices. The tube 5 is formed along the contour, it may happen - if the board length is greater than the theoretical tube circumference, a compression of the material, which is advantageous for the quality of the tube in terms of roundness and strength increase. In the latter case, the tube 5 can be held in the half-shell of the upper die tool 9 with staples or similar aids
Fig. 1 1 zeigt eine Vorrichtung zum Herstellen von Hohlprofilen, insbesondere Rohren 5, mit Vorbereitung einer neuen Platine 2. Zur weiteren Beladung wird in einer Transportvorrichtung 4 eine neue Platine 2 beispielsweise durch Sauger 17 oder ähnliches Transferwerkzeug, insbesondere seitlich vom Stempelwerkzeug 6 ange¬ ordnet, aufgenommen. Fig. 12 zeigt eine Vorrichtung zum Herstellen von Hohlprofilen, insbesondere Rohren 5, mit Vorbereitung einer neuen Platine 2. Durch eine Ausschiebevorrichtung in Axialrichtung 8, insbesondere das Stempelwerkzeug 6 selbst, wird das bereits fertig geformte Rohr in einen anderen Arbeitsbereich der Vorrichtung geschoben, wodurch das Biegeverfahren in einer Presse mit einem in Längsrichtung verschiebbaren Stempel- und Matrizenwerkzeug sowie Lade- und Entladevorrichtung verbunden wird. 1 1 shows an apparatus for producing hollow profiles, in particular tubes 5, with preparation of a new board 2. For further loading, a new board 2 is in a transport device 4, for example by suction 17 or similar transfer tool, in particular laterally from the punch tool 6 ¬ orders, recorded. 12 shows a device for producing hollow profiles, in particular tubes 5, with preparation of a new board 2. By a Ausschiebevorrichtung in the axial direction 8, in particular the punch tool 6 itself, the already finished molded tube is pushed into another working area of the device, thereby the bending process is connected in a press with a longitudinally displaceable punch and die tool and loading and unloading device.
Sobald ein Pressenstößel auf gleiche Höhenposition wie das Obermatrizenwerkzeug 12 eingefahren ist kann der axialer Positionstausch von Stempelwerkzeug 6 und Matrizenwerkzeug erfolgen. Das Stempelwerkzeug 6 steht nun wieder über dem Untermatrizenwerkzeug 12, die Seitenschieber 10 fahren ein, und die Platine 2 wird abgesetzt. Once a press ram is retracted to the same height position as the upper die tool 12, the axial position exchange of punch tool 6 and die tool can be done.
