- thin-walled starting materials such as sheet steel or aluminum sheet trays are generally used, with special shaping tools being required for each individual body part.
- the shaping tools comprise tool inserts with an engagement contour for realizing the cutting, embossing, bending or post-forming processes and are produced as separate components and connected to a base body, which may be a tool lower part, a tool upper part or else a slider.
- baubles When forming or cutting sheet metal, in particular when separating sheets of aluminum alloys, so-called baubles are produced. This generally refers to material particles that can detach from the cut surface or surface of the sheet during the process of forming and material separation. Tinsel can arise in small particles as dust, but also in particular when dividing with larger particle size, for example in the form of chips.
- Such a bauble formation is unfavorable during the production process, since baubles can come to a whirling up on component surfaces and / or tools and then lead to optically visible, impermissible chip marks on the component.

Description
Die Erfindung betrifft ein Formgebungswerkzeug zur Umformung von Metall- oder Nichtmetallwerkstoffen mit wenigstens einem Grundkörper, an welchem wenigstens ein Werkzeugeinsatz mit einer Eingriffskontur angeordnet ist.The invention relates to a forming tool for forming metal or non-metal materials with at least one base body on which at least one tool insert is arranged with an engagement contour.
Mit Formgebungswerkzeugen zur Umformung von Metall- oder Nichtmetallwerkstoffen werden Schneid-, Präge-, Umform-, Abkant- oder Nachformprozesse durchgeführt. Diese Formgebungswerkzeuge werden zur Herstellung von kleinen, insbesondere jedoch großen Blechbauteilen eines Fahrzeugs eingesetzt. Dabei werden in der Regel dünnwandige Ausgangsmaterialien, wie Stahlblech- oder Aluminiumblechbahnen verwendet, wobei für jedes einzelne Karosserieteil spezielle Formgebungswerkzeuge erforderlich sind.Cutting, embossing, forming, bending or postforming processes are carried out using forming tools for forming metal or non-metal materials. These shaping tools are used for the production of small, but in particular large sheet metal components of a vehicle. In this case, thin-walled starting materials, such as sheet steel or aluminum sheet trays are generally used, with special shaping tools being required for each individual body part.
Die Formgebungswerkzeuge umfassen Werkzeugeinsätze mit einer Eingriffskontur zur Realisierung der Schneid-, Präge-, Abkant- oder Nachformprozesse und werden als separate Bauteile hergestellt und mit einem Grundkörper, der ein Werkzeugunterteil, ein Werkzeugoberteil oder auch ein Schieber sein kann, verbunden.The shaping tools comprise tool inserts with an engagement contour for realizing the cutting, embossing, bending or post-forming processes and are produced as separate components and connected to a base body, which may be a tool lower part, a tool upper part or else a slider.
Beim Umformen oder Zerteilen von Blechen, insbesondere beim Trennen von Blechen aus Aluminiumlegierungen entsteht sogenannter Flitter. Damit werden allgemein Werkstoffpartikel bezeichnet, die sich beim Vorgang des Umformens und der Materialtrennung aus der Schnittfläche oder Oberfläche des Blechs ablösen können. Flitter kann dabei in kleinen Partikeln als Staub, aber auch insbesondere beim Zerteilen mit größerer Partikelgröße zum Beispiel in Form von Spänen entstehen.When forming or cutting sheet metal, in particular when separating sheets of aluminum alloys, so-called baubles are produced. This generally refers to material particles that can detach from the cut surface or surface of the sheet during the process of forming and material separation. Tinsel can arise in small particles as dust, but also in particular when dividing with larger particle size, for example in the form of chips.
Eine solche Flitterentstehung ist während des Produktionsprozesses ungünstig, da Flitter nach einer Aufwirbelung auf Bauteiloberflächen und/oder Werkzeugen gelangen und dann zu optisch sichtbaren, unzulässigen Spanabdrücken am Bauteil führen kann. Dadurch ergibt sich insbesondere bei Aluminium-Karosserieaußenhautteilen (im Vergleich zu Stahlaußenhautteilen) ein erhöhter kostenintensiver Ausschuss. Zudem führt Flitter zu einem erhöhten Reinigungsaufwand bei der Produktion und Werkzeugwartung und damit zu ungünstigen längeren und häufigeren Werkzeugstillständen.Such a bauble formation is unfavorable during the production process, since baubles can come to a whirling up on component surfaces and / or tools and then lead to optically visible, impermissible chip marks on the component. As a result, in particular with aluminum body shell parts (in comparison to steel skin parts), an increased cost-intensive scrap. In addition, tinsel leads to an increased cleaning effort during production and tool maintenance and thus to unfavorable longer and more frequent tool shutdowns.

Es ist Aufgabe der Erfindung ein verbessertes Formgebungswerkzeug zur Umformung von Metall- oder Nichtmetallwerkstoffen anzugeben, mit welchem in konstruktiv einfacher Weise die bei der Umformung der Metall- oder Nichtmetallwerkstoffen entstehenden Partikel, insbesondere Flitter abgesaugt werden können.It is an object of the invention to provide an improved forming tool for forming metal or non-metallic materials, with which in a structurally simple manner, the resulting in the transformation of the metal or non-metallic materials particles, in particular flakes can be sucked.

Erfindungsgemäß wird nach der erstgenannten Lösung ein Formgebungswerkzeug zur Umformung von Metall- und Nichtmetallwerkstoffen geschaffen, mit
- wenigstens einem Grundkörper, an welchem wenigstens ein Werkzeugeinsatz mit einer Eingriffskontur angeordnet ist, und
- einer im Bereich der Eingriffskontur zur Absaugung von Flitter angeordnete und eine Düsenöffnung aufweisende Absaugdüse, die mit einer den Coanda-Effekt nutzenden Unterdruckpumpe verbunden ist.
- at least one base body on which at least one tool insert is arranged with an engagement contour, and
- a arranged in the region of the engagement contour for the extraction of tinsel and a nozzle opening having suction nozzle, which is connected to a Coanda effect using vacuum pump.
Bei einem solchen erfindungsgemäßen Formgebungswerkzeug ist für die Absaugung von Flitter nur ein konstruktiv geringer Aufwand erforderlich, da die realisierte Absaugeinrichtung lediglich aus einer im Bereich der Eingriffskontur angeordneten Absaugdüse und einer den Coanda-Effekt nutzenden Unterdruckpumpe aufgebaut ist, wobei diese Baugruppen über Rohrleitungen oder Schläuche miteinander verbunden sind.In such a shaping tool according to the invention only a structurally low effort is required for the extraction of tinsel, since the realized suction device is composed only of a suction nozzle arranged in the region of the engagement contour and a vacuum pump using the Coanda effect, these assemblies via pipes or hoses together are connected.
Besonders vorteilhaft ist es, wenn weiterbildungsgemäß das Formgebungswerkzeugs einen mit der Unterdruckpumpe verbundenen Auffangbehälter zur Aufnahme des abgesaugten Flitters aufweist. Damit wird verhindert, dass der Flitter aus den mit der Unterdruckpumpe verbundenen Rohrleitungen oder den Schläuchen unkontrolliert ausgeblasen wird. Ansonsten könnte der Flitter auch über ein offenes Ende der/des mit der Unterdruckpumpe verbundenen Rohrleitung oder Schlauchs in einen Abfallschacht geleitet werden. Nach einer vorteilhaften Weiterbildung der Erfindung nach der erstgenannten Lösung ist zum Scherschneiden der Werkzeugeinsatz als Schneidmesser mit einer Schneidkante als Eingriffskontur ausgebildet, wobei die Absaugdüse eine spaltförmige Düsenöffnung mit einem rechteckigen, ovalen oder elliptischen Öffnungsquerschnitts aufweist und sich im Bereich der Schneidkante erstreckt.It is particularly advantageous if, according to further development, the shaping tool has a collecting container connected to the vacuum pump for receiving the sucked-out bauble. This prevents the bauble from being blown out of the pipes or hoses connected to the vacuum pump in an uncontrolled manner. Otherwise, the bauble could also be routed to an outlet shaft via an open end of the pipe or hose connected to the vacuum pump. According to an advantageous development of the invention according to the first-mentioned solution, the tool insert is designed as a cutting blade with a cutting edge as an engagement contour for shearing, wherein the suction nozzle has a slit-shaped nozzle opening with a rectangular, oval or elliptical opening cross-section and extending in the region of the cutting edge.
Besonders vorteilhaft ist es dabei, wenn weiterbildungsgemäß die Absaugdüse bezüglich einer Schneidfläche des Schneidmessers gegenüberliegend zur Schneidkante derart an dem Schneidmesser angeordnet ist, dass die Düsenöffnung in Normalenrichtung einer Aktivfläche der Eingriffskontur, d.h. einer Schneidfläche der Schneidkante gegenüber der Ebene dieser Aktivfläche bzw. Schneidfläche einen Überstand aufweist. Damit kann der Flitter in Schneidrichtung unmittelbar in die Düsenöffnung abgesaugt werden, bevor er sich in dem Formgebungswerkzeug verbreiten kann.It is particularly advantageous if, in accordance with further development, the suction nozzle is arranged with respect to a cutting surface of the cutting blade opposite the cutting edge on the cutting blade such that the nozzle opening in the normal direction of an active surface of the engagement contour, i. a cutting surface of the cutting edge with respect to the plane of this active surface or cutting surface has a projection. Thus, the bauble can be sucked in the cutting direction directly into the nozzle opening before it can spread in the forming tool.
Alternativ ist weiterbildungsgemäß die Absaugdüse an dem Schneidmesser derart angeordnet, dass die Düsenöffnung gegenüber einer Ebene einer Aktivfläche der Eingriffskontur, d.h. einer Schneidfläche der Schneidkante In Bezug auf den Werkzeugeinsatz bzw. dem Schneidmesser nach innen versetzt ist. Damit wird das von dem Werkstück abgetrennte Teil durch die Absaugdüse beim Herabfallen nicht behindert.Alternatively, according to the invention, the suction nozzle is arranged on the cutting blade such that the nozzle opening is opposite to a plane of an active surface of the engagement contour, i. a cutting surface of the cutting edge is offset in relation to the tool insert or the cutting blade inwards. Thus, the separated from the workpiece part is not hindered by the suction when falling.

Besonders vorteilhaft ist es, wenn bei dieser zweitgenannten Lösung weiterbildungsgemäß das Formgebungswerkzeugs mit einem mit der Unterdruckpumpe verbundenen Auffangbehälter zur Aufnahme des abgesaugten Flitters ausgebildet ist. Damit wird verhindert, dass der Flitter aus den mit der Unterdruckpumpe verbundenen Rohrleitungen oder den Schläuchen unkontrolliert ausgeblasen wird. Ansonsten könnte der Flitter auch über ein offenes Ende der/des mit der Unterdruckpumpe verbundenen Rohrleitung oder Schlauchs in einen Abfallschacht geleitet werden.It is particularly advantageous if, in the case of this second-mentioned solution, the shaping tool is designed with a collecting container connected to the vacuum pump for receiving the sucked-out bauble. This prevents the bauble from being blown out of the pipes or hoses connected to the vacuum pump in an uncontrolled manner. Otherwise, the bauble could also be routed to an outlet shaft via an open end of the pipe or hose connected to the vacuum pump.
