Ein Maschinengestell 5 der Biegepresse 1 besteht beispielsweise aus einer Bodenplatte 6 auf der vertikal aufragend, zueinander beabstandet und parallel zueinander ausgerichtete Seitenwangen 7, 8 angeordnet sind. Diese sind bevorzugt durch einen massiven, beispielsweise aus einem Blechformteil gebildeten Querverband 9 an ihren von der Bodenplatte distanzierten Endbereichen verbunden.A
Die Seitenwangen 7, 8 sind zur Bildung eines Freiraumes für das Umformen des Werkteils 3 etwa C - förmig, wobei an Frontstirnflächen 10 von bodennahen Schenkeln der Seitenwangen 8 ein feststehender, auf der Bodenplatte 7 aufstehender Tischbalken 11 befestigt ist. An Frontstirnflächen 12 von Bodenentfernten Schenkeln ist in Linearführungen 13 ein zum Tischbalken 11 relativ verstellbarer Druckbalken 14 gelagert. Auf einander gegenüberliegenden, parallel zueinander verlaufenden Stirnflächen 15, 16 des Tischbalkens 11 und Druckbalkens 14 sind Werkzeugaufnahmen 17 zur Bestückung mit dem Biegewerkzeugen 4 angeordnet.The
Die gezeigte Biegepresse 1 weist als Antriebsanordnung 18 für den verstellbaren Druckbalken 14 zwei mit elektrischer Energie betriebene Antriebsmittel 19 auf, die mit einer aus einem Energienetz 20 angespeisten Steuereinrichtung 21 leitungsverbunden sind. Über ein mit der Steuereinrichtung 21 leitungsverbundenes Eingabeterminal 22 wird beispielsweise der Betrieb der Biegepresse 1 gesteuert.The
Erwähnt sei, dass als Antriebsmittel 19 sowohl durch ein Druckmedium beaufschlagte Zylinder möglich sind, aber auch elektromotorisch betrieben Spindeltriebe 23, z.B. mit einer in einem Gehäuse drehend angetriebenen Spindelmutter mit einer mit dem Druckbalken verbundenen Gewindespindel als Stellmittel. Der Antrieb der Spindelmutter kann beispielsweise durch einen hochpoligen Elektromotor, z.B Torque- Motor, erfolgen.It should be mentioned that as a drive means 19 both acted upon by a pressure medium cylinder are possible, but also electromotively operated
Stellmittel 24 der Antriebsmittel 19 sind für eine reversible Stellbewegung des Druckbalkens 14 mit diesem antriebsverbunden, wobei zum Ausgleich etwaiger Verformungen des Druckbalkens 14 bzw. einer Stützlagervorrichtung 25 für die Antriebsmitteln 19 durch Befestigungsmitteln 26, z.B. Bolzen, erfolgt.Adjusting means 24 of the drive means 19 are drivingly connected to this for a reversible adjusting movement of the
Der Tischbalken 11 weist bei der gezeigten Ausbildung eine Tischausnehmung 27 auf um einen Freiraum für Beine einer Bedienungskraft zu schaffen, womit die Bedienung der Biegepresse 1 sitzend möglich ist, z.B. bei einer Kleinteile- Serienfertigung. Allerdings ist diese Ausbildung eher für Biegepresse 1 geringerer Druckleistung infolge der reduzierten Verformungsfestigkeit des Tischbalkens 11 geeignet.The

Wie weiter der
Die Schwächungszonen beidseits des Befestigungsmittels 26 des Stellmittels 24 mit dem Druckbalken 14 ermöglichen einen Ausgleich bei einer Verformung des Druckbalkens 14, wie sie beispielsweise bei einer mittigen Belastung durch den Umformvorgang des Werkteils 3 zwischen den Biegewerkzeugen 4 eintritt und anhand der in unterbrochenen Linien eingezeichneten Biegelinie 33 für den Druckbalken 14 dargestellt ist.The weakening zones on both sides of the fastening means 26 of the adjusting means 24 with the
Der Ausgleich wird durch eine Federwirkung in Folge der Schwächungszonen erreicht und wird dadurch ein durch die Anordnung der Antriebsmittel 19 vorgegebener Abstand 34 zwischen den Kraftwirklinien der beiden Antriebsmitteln 19 beibehalten und damit auf die Stellmittel 24 einwirkende seitliche Belastungen vermieden.The compensation is achieved by a spring action as a result of the weakening zones and is thereby maintained by the arrangement of the drive means 19
Weiters bewirken diese Schwächungszonen bei einer über einer gesamten Länge 35 des Druckbalkens 14 gleichmäßig verteilt aufgebrachte Kraft, zum Beispiel bei einem Umformvorgang über die gesamte Länge 35 des Druckbalkens 14 eine Gegenverformung der Biegelinie 33 in den entgegen gesetzen Endbereichen des Druckbalkens 14 und werden dadurch geringere Maßnahmen eines Biegewinkelausgleiches am Werkteil 3 erforderlich.Furthermore, these weakening zones effect a force uniformly distributed over an
In den
Damit wird zum einen eine Verformung des Druckbalkens 14 bei einer zentrischen Belastung gemäß der ebenfalls in unterbrochenen Linien eingezeichneten Biegelinie 33 möglich ohne einer Auswirkung auf den Abstand 34, wobei dies durch eine oberhalb der Schwächungszone 38 verbleibende Brücke 39 zwischen den Anlenkbereichen der Befestigungsmittel 26 am Druckbalken 14 erreicht wird.Thus, on the one hand a deformation of the
Die Schwächungszone 38 im Druckbalken 14 kann beispielsweise durch einen Schlitz aber auch durch eine nutförmige Vertiefung in der Oberfläche mit verbleibendem Wandsteg, etc. gebildet sein. Weiter besteht die Möglichkeit den Schwächungszonen überbrückend ein Aktuator, z.B. mit einem Druckmedium beaufschlagbarer Zylinder, vorzusehen, mit dem der Schwächungsgrad reguliert werden kann.The weakening

Auf dem die Seitenwangen 7, 8 verbindenden Querverband 9 ist die durch eine Montageplatte 40 gebildete Stützlagervorrichtung 25 befestigt.On the
Die Montageplatte 40 ist in dem Abstand 34 der Antriebsmittel 19 mit zwei Bohrungen 41 versehen die von einem Gehäuseansatz 42 und den Stellmitteln 24 des Antriebsmittel 19 durchragt werden. Die Bohrungen 41 umfassend sind Montageringe 43 zur Auflagerung des Antriebsmittels 19, beispielsweise mittels eines nicht weiter gezeigten Flansches ausgebildet, die durch die Ausbildung von den Seitenwangen 8 zugewandten Randausnehmungen 40 und eines im Mittel zwischen den Bohrungen 41 vorgesehenen Durchbruches 45 gebildeten Stützstegen 46, 47 mit durch Randleisten 48, 49 gebildeten Montagebereich verbunden sind. Die Montageplatte 40 ist beispielsweise mit den Querverband 9 ausbildenden Profilen verschraubt.The mounting
Durch die Ausbildung der Stützstege 46, 47 durch die Randausnehmungen 44 und dem Durchbruch 45 werden Schwächungsbereiche in der Verbindung der Montageringe 43 mit den Randleisten 48, 49 ausgebildet, die eine geringfügige Verschwenkbarkeit der Oberflächen 51, 52 der Montageringe 43 aufnehmenden Ebenen ermöglichen, wodurch unabhängig einer unter Belastung auftretenden Verformung des Maschinengestells entgegenwirkend, eine parallele Ausrichtung von Mittelachsen der Antriebsmittel 19 und damit den Kraftwirklinien 29 gewährleistet wird. Damit wird eine im Bezug auf die Antriebsmitteln 19 zentrische Kraftübertragung zwischen diesen und dem Druckbalken 14 erreicht und seitliche Krafteinwirkungen auf die Stellmittel 24 und Lageranordnung der Antriebsmitteln 19 wirkungsvoll vermieden.Due to the formation of the

In weiterer Folge beschränkt sich die Beschreibung auf eine der identisch ausgebildeten Montageplatten 40 die für die Aufnahme je eines der Antriebsmittel 19 ausgebildet sind und getrennt auf dem Querverband 9 zwischen den Seitenwangen 7, 8 des Maschinengestells 5 befestigt sind.Subsequently, the description is limited to one of the identically formed mounting
Die Montageplatte 40 weist die vom Stellmittel 24 des Antriebsmittels 19 durchragte Bohrung 41 auf. Konzentrisch zur Bohrung 41 sind in Richtung der Randleisten 48, 49 distanzierte, kreisbogenförmig verlaufende Durchbrüche 45 vorgesehen, wodurch die Bohrung 41 umgebend der Montagering 43 gebildet ist, der für die Befestigung des Antriebsmittels 19 mit einem nicht weiter gezeigten Flansch vorgesehen ist.The mounting
Scheitelpunkte der kreisbogenförmig verlaufenden Durchbrüche 45 sind den Randleisten 48, 49 zugeordnet, wobei einander gegenüber liegende Endbereiche der Durchbrüche 45 zueinander beabstandet sind wodurch zwei diametral gegenüberliegende Verbindungsstege 53, 54 mit einem ringförmigen Plattenbereich 55 bestehen, der mit dem durch die Randleisten 48, 49 gebildeten Montagebereich 50 über die bereits in der vorhergehenden Figur beschriebenen, durch die Randausnehmungen 54 gebildeten Stützstegen 46, 47 verbunden ist.Vertexes of the circular arc-shaped
Durch die um 90° versetzte Anordnung der Verbindungsstege 53, 54 zu den Stützstegen 46, 47 und der dadurch gebildeten Schwächungsbereiche werden um 90° versetze, theoretische Schwenkachsen 56, 57 gebildet, die es ermöglichen, eine in der Oberfläche 51 des Montageringes 43 sich erstreckende Ebene eine geringfügige Verschwenkung um die Schwenkachse 56 und die Schwenkachse 57 vorzunehmen und damit wie bereits in der vorhergehenden Figur beschrieben, einen Ausgleich für etwaige lastbedingte Verformungen des Maschinengestells 5 zu kompensieren um unabhängig vom Belastungsfall, eine parallele Ausrichtung der Kraftwirklinien 29 zu erreichen und auf die Stellmitteln 24 und Antriebsmitteln 19 einwirkende Querkräften zu vermeiden.Due to the offset by 90 ° arrangement of the connecting
Die Ausführungsbeispiele zeigen mögliche Ausführungsvarianten der Biegepresse, wobei an dieser Stelle bemerkt sei, dass die Erfindung nicht auf die speziell dargestellten Ausführungsvarianten derselben eingeschränkt ist, sondern vielmehr auch diverse Kombinationen der einzelnen Ausführungsvarianten untereinander möglich sind und diese Variationsmöglichkeit aufgrund der Lehre zum technischen Handeln durch gegenständliche Erfindung im Können des auf diesem technischen Gebiet tätigen Fachmannes liegt.
