Definitions
- the invention relates to a device for producing tubes from asymmetrically pre-bent metal sheets according to the progressive shape method.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Herstellen von Rohren aus asymmetrisch vorgebogenen Blechtafeln nach dem fortschreitenden Form - Verfahren In einer Rohrformpresse mit einem am Pressenoberteil befestigten Biegeschwert, an dessen Fuß ein oberes Formwerkzeug gelenkig gelagert angeordnet ist, und einem Pressenunterteil mit einem unteren Formwerkzeug, wobei das Biegeschwert mit dem oberen Formwerkzeug zum Umformvorgang außermittig auf die vorgebogene Blechtafel aufsetzt.The invention relates to a device for producing tubes from asymmetrically pre-bent metal sheets according to the progressive shape method. In a tube forming press with a bending bar attached to the press upper part, at the foot of which an upper mold is articulated, and a lower press part with a lower mold, wherein the Biegeschwert with the upper mold for forming process off-center on the pre-bent metal sheet touches.
Bekannte Verfahren zur Herstellung von Rohren aus Blechtafeln sind das UOE - Verfahren, das Dreiwalzen - Biegeverfahren, das Spiral und das Rohrformpressenverfahren. Beim Rohrformpressen wird unterschieden nach dem fortschreitenden Falz - Verfahren und dem fortschreitenden Form - Verfahren.Known methods for producing tubes from sheet panels are the UOE process, the three-roll bending process, the spiral and the tube molding process. In tube forming, a distinction is made between the progressive folding method and the progressive forming method.
Für eine U-Presse, mit der ein ebenes Blech umgeformt wird, ist es durch die JP-A-59199116 bekanntgeworden, an einem ersten, starren Formwerkzeug des Biegeschwertes mit kämmendem Eingriff an beiden Außenseiten des Formwerkzeugs weitere, segmentierte Formwerkzeuge gelenkig gelagert vorzusehen. Die weiteren Formwerkzeuge sind von zusätzlich erforderlichen Zylindereinhelten temporär verstellbar und auf ein neues, festes Werkzeugendmaß einstellbar. Mit demselben, jeweils neu einzustellenden Werkzeug sollen im Durchmesser verschieden große Rohre hergestellt werden.For a U-press, with which a flat sheet is formed, it has become known through JP-A-59199116, provided on a first rigid mold of the bending rate with meshing engagement on both outer sides of the mold further, segmented molds hinged. The other molds are temporarily adjustable by additionally required cylinder pockets and adjustable to a new, fixed Werkzeugendmaß. With the same, each new tool to be adjusted in diameter different sized pipes are made.
Aus der DE-A-1 183 465 und JP-A-62 142 026 Ist es zum Umformen eines ebenen Bleches bekannt, mit nur einem Werkzeug unterschiedliche Arbeitsgänge durchzuführen. Das Oberwerkzeug ist dazu mit zwei verschiedenen Formwerkzeugen ausgebildet und insgesamt verschwenk- bzw. drehbar. Es kann somit wahlweise das eine oder das andere Formwerkzeug zum Einsatz mit dem Unterwerkzeug gebracht werden.From DE-A-1 183 465 and JP-A-62 142 026 it is known for forming a flat sheet, with a single tool different operations perform. The upper tool is for this purpose formed with two different molds and a total of pivoting or rotatable. It can thus be optionally brought one or the other mold for use with the lower tool.
Für die Herstellung eines Rohres bzw, Großrohres nach dem fortschreitenden Form - Verfahren sind mehrere aufeinanderfolgende Arbeitsschritte erforderlich. Die Blechtafel wird in einem ersten Schritt an den Längskanten vorgebogen. Die Vorbiegung wird üblicherweise in einer separaten Kantenbiegepresse vorgenommen. Das Vorbiegen der Längskanten erfolgt, damit der Rohrradius bei der Verformung zum Schlitzrohr im Bereich der späteren Naht, dort wo die Längskanten der zu dem Rohr umgebogenen Blechtafel aneinanderstoßen, gleichmäßig ausgeformt ist.For the production of a pipe or large pipe according to the progressive molding process several sequential steps are required. The metal sheet is pre-bent at the longitudinal edges in a first step. The pre-bend is usually done in a separate edge press. The pre-bending of the longitudinal edges takes place so that the tube radius is uniformly formed during deformation to the slot tube in the region of the later seam, where the longitudinal edges of the bent to the tube sheet metal plate abut each other.
Die vorgebogene Blechtafel wird nun dem eigentlichen Biegeprozess in der Rohrformpresse unterworfen.The pre-bent metal sheet is now subjected to the actual bending process in the tube forming press.
Die Rohrformpresse besteht aus einem beweglichen Ober- und Unterteil. Mit dem oberen Teil der Rohrformpresse ist ein senkrecht angeordnetes Biegeschwert verbunden, an dessen Fuß wiederum das obere Formwerkzeug befestigt ist.The tube forming press consists of a movable upper and lower part. Connected to the upper part of the tube forming press is a vertically arranged bending bar, at the foot of which the upper forming tool is fastened.
Das untere Formwerkzeug besteht in einer einfachen Ausführung aus zwei Leisten, welche in einem veränderbaren Abstand zueinander in Längsrichtung angeordnet sind. Diese beiden Leisten bilden die unteren Widerlager für die zu verformende Blechtafel.The lower mold consists in a simple embodiment of two strips, which are arranged at a variable distance from each other in the longitudinal direction. These two strips form the lower abutments for the metal sheet to be deformed.
Die an der Längsseite vorgebogene Blechtafel wird in einem weiteren Schritt in die Rohrformpresse eingeschoben und dann durch Niederdrücken des Pressenoberteils eine Blegekraft auf die Blechtafel aufgebracht, wobei sich unter der Einwirkung des Biegeschwertes und des von diesem getragenen, oberen Formwerkzeugs eine Verformung der Blechtafel einstellt. Dieser Arbeitsablauf wird mehrmals wiederholt, bis die Blechtafel zu einem Schlitzrohr umgeformt wurde.The pre-bent on the longitudinal side plate is inserted in a further step in the tube forming press and then applied by depressing the press top a Blegekraft on the metal sheet, which is under the action of the bending load value and carried by this upper mold sets a deformation of the metal sheet. This procedure is repeated several times until the metal sheet has been formed into a slotted pipe.
Die Zeit zur Herstellung eines Schlitzrohres hängt somit ab von der Anzahl der Hübe der Rohrformpresse und diese wiederum von dem Bereich, der bei einem Hub umgeformt wird. Dieser Umformbereich wird durch die Breite des Formwerkzeuges vorgegeben.The time to make a slit pipe thus depends on the number of strokes of the tube forming press, and this in turn on the area that is formed at a stroke. This forming area is determined by the width of the molding tool.
Das am Fuß des Biegeschwertes angebrachte Formwerkzeug besitzt eine Breite, die ein mehrfaches des Querschittes des Biegeschwertes ist und weist einen Formradius auf, der von dem Innenradius des herzustellenden Rohres abhängt. Dieses stempelartige, gerundete Formwerkzeug setzt bei der vertikalen Bewegung asymmetrisch auf der Blechtafel auf, da diese asymmetrisch vorgeformt ist. Hierdurch entsteht ein Biegemoment im Biegeschwert. Damit das Biegeschwert bei solch einer asymmetrischen Belastung nicht ausknickt, wird es mit einem dieses Biegemoment berücksichtigenden Querschnitt ausgelegt.The mold attached to the base of the bending load value has a width which is a multiple of the transverse section of the bending load value and has a forming radius which depends on the inner radius of the pipe to be produced. This stamp-like, rounded molding tool sets asymmetrically on the metal sheet in the vertical movement, since this is preformed asymmetrically. This creates a bending moment in the bending rate. So that the bending rate does not buckle under such an asymmetric load, it is designed with a cross-section taking into account this bending moment.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art so auszubilden, dass ein größerer Bereich der zu verformenden Blechtafel gebogen werden kann, ohne die Belastung des Biegeschwertes zu erhöhen.The invention is therefore based on the object, a device of the type described above in such a way that a larger area of the metal sheet to be deformed can be bent without increasing the burden of bending load.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Formwerkzeug frei beweglich am Fuß des Biegeschwertes gelagert, dort vorzugsweise durch Drehgelenke befestigt ist und beim Aufsetzen auf die vorgebogene Blechtafel um seine horizontale Längsachse ausschwenkt.This object is achieved in that the mold mounted freely movable at the bottom of the bending load, there is preferably fixed by hinges and pivots when placing on the pre-bent metal sheet around its horizontal longitudinal axis.
Mit der erfindungsgemäß gelenkigen Befestigung des Formwerkzeuges am Fuß des Biegeschwertes läßt sich erreichen, dass beim Aufsetzen des Formwerkzeuges auf der Blechtafel ein Ausschwenken um die horizontale Längsachse ermöglicht wird.With the invention hinged attachment of the mold at the foot of the bending rate can be achieved that when placing the mold Swinging around the horizontal longitudinal axis is made possible on the metal sheet.
Beim Herabfahren bzw. Absenken des Biegeschwertes in Richtung auf das untere Formwerkzeug mit der aufgelegten Blechtafel erfolgt mit dem am Fuß befestigten oberen Formwerkzeug ein erster Kontakt zwischen dem Radius des Formwerkzeuges und der Blechtafel auf der Seite des Biegeschwertes, die der vorgebogenen Blechtafelseite abgewandt ist. Durch die gelenkige Lagerung in der horizontalen Längsachse kann sich das obere Formwerkzeug auf der Oberfläche der Blechtafel abrollen und somit einen größeren Verformungsbereich bestreichen, bis die Blechtafel auf z.B. den beiden Leisten des unteren Formwerkzeuges aufliegt. Ab diesem Zeitpunkt beginnt die Verfornung der Blechtafel über den Radius des oberen Formwerkzeuges.When lowering or lowering of the bending rate in the direction of the lower mold with the laid metal sheet takes place with the foot attached to the upper mold a first contact between the radius of the mold and the metal sheet on the side of the bending value, which faces away from the pre-bent metal sheet side. Due to the hinged mounting in the horizontal longitudinal axis, the upper mold can roll on the surface of the metal sheet and thus spread a larger deformation range until the metal sheet on e.g. rests on the two bars of the lower mold. From this point on, the perforation of the metal sheet begins over the radius of the upper mold.
Eine weitere Ausführungsform sieht vor, dass zusätzlich das Biegeschwert gelenkig am Pressenoberteil befestigt wird. Durch diese Maßnahme der zweigelenkigen Ausführung wird erreicht, daß beim Biegen keine Momente im Schwert entstehen, abgesehen von durch die Reibung in den Gelenken hervorgerufenen sehr geringen Momenten.Another embodiment provides that in addition the bending bar is hinged to the press upper part. By this measure, the two-hinged design ensures that no bending moments occur in the sword, apart from caused by the friction in the joints very low moments.
Der Reibwert der Relativbewegung zwischen dem oberen Formwerkzeug und dem Biegeschwert bzw. dem Biegeschwert und dem Oberteil der Presse kann durch die Wahl einer Schmierung und die Wahl der Gleitpaarungen beeinflußt werden.The coefficient of friction of the relative movement between the upper mold and the bending rate or the bending rate and the upper part of the press can be influenced by the choice of lubrication and the choice of the sliding pairings.

Am Pressenoberteil 3 der Formpresse 1 ist ein Biegeschwert 4 vorzugsweise lösbar befestigt. Durch das von einem nicht dargestellten Antrieb heb- und senkbare Pressenoberteil 3 erfolgt eine entsprechende vertikale Bewegung des Biegeschwertes 4.
Auf dem Pressenunterteil 2 ist ein unteres Formwerkzeug 5, hier bestehend aus zwei Formleisten 6 und 6', angeordnet, während das Biegeschwert mit einem oberen Formwerkzeug 8 versehen ist.
