Description
Die Erfindung betrifft ein Verfahren zum Herstellen eines Stanzteiles mit vergrößerter Funktionsfläche, insbesondere Feinschneiden eines Werkstücks aus einem Bandstreifen, bei dem der Bandstreifen zwischen einem aus einem Schneidstempel, einer Führungsplatte für den Schneidstempel, einer an der Führungsplatte angeordneten Ringzacke und einem Ausstosser zusammengesetzte Oberteil und einem aus Schneidplatte und Auswerfer bestehenden Unterteil beim Schließen eingespannt und die Ringzacke in den Bandstreifen eingedrückt wird.The invention relates to a method for producing a stamped part with an enlarged functional surface, in particular fine cutting a workpiece from a tape strip, in which the tape strip between a top of a cutting punch, a guide plate for the cutting punch, arranged on the guide plate ring teeth and an ejector shell and a clamped from the cutting plate and ejector existing lower part when closing and the ring point is pressed into the tape strip.
Die Erfindung betrifft weiterhin Vorrichtungen zum Herstellen eines Stanzteiles mit vergrößerter Funktionsfläche, insbesondere Feinschneiden eines Werkstücks aus einem Bandstreifen, mit einem zweiteiligen Werkzeug, das Mindestens ein Schneidstempel, eine Führungsplatte für den Schneidstempel, eine an der Führungsplatte angeordnete Ringzacke, einen Ausstosser, eine Schneidplatte und einen Auswerfer umfasst, wobei der Bandstreifen zwischen Führungsplatte und Schneidplatte eingespannt ist und die Ringzacke in den Bandstreifen eingedrückt ist.The invention further relates to devices for producing a stamped part with an enlarged functional surface, in particular fine cutting a workpiece from a strip of tape, with a two-part tool, the At least one cutting punch, a guide plate for the cutting punch, arranged on the guide plate ring prong, a pusher, a cutting plate and an ejector, wherein the tape strip between the guide plate and cutting plate is clamped and the ring prong is pressed into the tape strip.
In der Feinschneid- und Umformtechnik werden vorwiegend Stähle verarbeitet. Dabei erstreckt sich die Vielfalt verwendeter Werkstoffe von einfachen Baustählen bis hin zu hochfesten Feinkornstählen. Die Ressource "Werkstoff" hat in den letzten Jahren stark an Bedeutung gewonnen. Mit einer optimalen Werkstoffausnutzung lassen sich die Herstellkosten eines Bauteiles wesentlich beeinflussen. Die hochfesten Stähle ermöglichen dünnwandigere Bauteile bei gleichem Festigkeitsverhalten.
In den meisten Fällen wirkt die Schnittfläche beim Feinschneiden als Funktionsfläche, weshalb der Einzug einen Kostenfaktor darstellt.In fineblanking and forming technology, mainly steels are processed. The variety of materials used extends from simple structural steels to high-strength fine-grained steels. The resource "material" has gained in importance in recent years. With optimal material utilization, the production costs of a component can be significantly influenced. The high-strength steels enable thinner-walled components with the same strength behavior.
In most cases, the cut surface acts as a functional surface during fineblanking, which is why the feeder is a cost factor.
Typische Merkmale von Feinschnittteilen sind der Kanteneinzug und der Schnittgrat. Insbesondere in Eckenpartien stellt sich der Einzug ein, der mit kleiner werdendem Eckenradius und steigender Blechdicke zunimmt. Die Einzugstiefe kann rd. 30% und die Einzugsbreite etwa 40% der Blechdicke oder mehr betragen (siehe DIN 3345, Feinschneiden, Aug. 1980). Der Einzug ist damit abhängig von Materialdicke und -qualität, so dass seine Steuerung nur begrenzt möglich ist und oft eine Einschränkung der Teilefunktion, beispielsweise durch eine fehlende Scharfkantigkeit der Ecken bei Verzahnungsteilen oder durch die hervorgerufene Änderung der Funktionslänge der Teile, mit sich bringt.
Der Stanzeinzug reduziert deshalb die Teilefunktion, und zwingt den Hersteller zur Verwendung eines dickeren Ausgangsmaterials.Typical features of fine cut parts are the edge indent and the cutting edge. In particular, in corner parts, the feeder, which increases with decreasing the corner radius and increasing sheet thickness. The insertion depth can be approx. 30% and the feed width is about 40% of the sheet thickness or more (see DIN 3345, fineblanking, Aug. 1980). The feeder is thus dependent on material thickness and quality, so that its control is limited and often a limitation of the part function, For example, by a lack of sharp edges of the corners in teeth or by the induced change in the functional length of the parts, brings with it.
The punch pull therefore reduces the parting function and forces the manufacturer to use a thicker stock.

Also in this known solution, the feeder is ultimately not eliminated and material volume is displaced along the cutting line, which is accompanied by an increased risk of cracking.
Bei diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, den Kanteneinzug gezielt durch Erzeugen eines dem Volumen entsprechenden Einzugs innerhalb der Teilegeometrie bei gleichzeitiger Beibehaltung der Funktionsflächen an dünneren Feinschneidteilen unter Einsparung von Material weitgehend zu vermeiden, ohne dass das Material entlang der Schnittlinie bewegt wird.In this prior art, the present invention seeks to avoid the edge feed targeted by generating a volume corresponding intake within the part geometry while maintaining the functional surfaces of thinner fine cutting parts while saving material, without the material is moved along the cutting line ,
Diese Aufgabe wird durch ein Verfahren der eingangs genannten Gattung mit den kennzeichnenden Merkmalen des Anspruchs 1 und durch eine Vorrichtung mit den kennzeichnenden Merkmalen der Ansprüche 10 und 11 gelöst.This object is achieved by a method of the type mentioned above with the characterizing features of
Vorteilhafte Ausgestaltungen des Verfahrens und der Vorrichtung sind den Unteransprüchen entnehmbar.Advantageous embodiments of the method and the device are the dependent claims.
Die erfindungsgemäße Lösung zeichnet sich dadurch aus, dass es erstmals möglich wird, das Feinschneidverfahren auf Teile, beispielsweise Verzahnungsteile mittlerer und größerer Dicke mit scharfen Kanten ohne Nachbearbeitung und Materialverschiebung entlang der Schnittlinie wirtschaftlich anzuwenden.The solution according to the invention is characterized in that it is possible for the first time to economically apply the fine blanking process to parts, for example toothed parts of medium and greater thickness with sharp edges without post-processing and material displacement along the cutting line.
Dies wird dadurch erreicht, dass vor Beginn des Schnitts am eingespannten unbehandelten Bandstreifen entgegen der Schneidrichtung mit einem Vorformelement ein zur Schnittrichtung negatives Vorformen durchgeführt wird, das dem erwarteten Kanteneinzug beim Schneiden in die Schneidplatte in Größe und Geometrie zuzüglich einer Zugabe entspricht und ein Materialvolumen in gespiegelter Form an der Einzugsseite erzeugt. Mit Beginn und während des Schnitts wird der so vorgeformte Bereich des eingespannten Bandstreifens durch das Vorformelement abgestützt.This is achieved by counteracting the clamped, untreated strip of tape prior to commencing the cut the cutting direction is performed with a preforming element a negative preforming to the cutting direction, which corresponds to the expected Kanteneinzug when cutting into the insert in size and geometry plus an addition and generates a volume of material in a mirrored form on the feed side. At the beginning and during the cut, the thus preformed area of the clamped tape strip is supported by the preform element.
Von besonderem Vorteil ist, dass die Prozessparameter für das Vorformen, beispielsweise die Geometrie und das Werkstoffvolumen des vorzuformenden Bereichs, in Abhängigkeit von Materialart, Form und Geometrie des Werkstücks durch eine virtuelle Umformsimulation bestimmt werden. Dies führt zu einer schnellen praxisnahen Auslegung der Vorformelemente, insbesondere der Bestimmung der Vorformwinkel an den Vorformelementen.
Die Prozessparameter für das Vorformen lassen sich aber durch Vermessen an real hergestellten Feinschnittteilen iterativ bestimmen, ohne die Erfindung zu verlassen.It is particularly advantageous that the process parameters for preforming, for example the geometry and the material volume of the region to be preformed, are determined by a virtual forming simulation as a function of the material type, shape and geometry of the workpiece. This leads to a fast practical design of the preform elements, in particular the determination of the preform angles on the preform elements.
However, the process parameters for the preforming can be iteratively determined by measuring on actually produced fine-cut parts, without departing from the invention.
Das erfindungsgemäße Verfahren ist variabel einsetzbar. So kann das Vorformen in einer separaten Vorstufe innerhalb eines Werkzeugs als Folgeschnitt durchgeführt werden. Es ist aber auch im Komplettschnitt unproblematisch ausführbar, wenn der Auswerfer zugleich als Vorformelement verwendet wird, wobei der Komplettschnitt nach dem erfindungsgemäßen Verfahren besonders vorteilhaft für dünnere Teile anwendbar ist.
Das erfindungsgemäße Verfahren deckt somit das Feinschneiden von Teilen in einem breiten Abmessungsbereich, beispielsweise Teile bis zu mittleren Dicken und kleinere bis mittlere Abmessungen im Komplettschnitt und Teile bis zu großen Dicken und Abmessungen im Folgeschnitt, ab.The method according to the invention can be used variably. Thus preforming can be carried out in a separate preliminary stage within a tool as a follow-up cut. However, it is also feasible without problems in the complete section, if the ejector is also used as a preform element, the complete section by the method according to the invention is particularly advantageous for thinner parts applicable.
The inventive method thus covers the fine blanking of parts in a wide dimensional range, for example, parts up to average thicknesses and smaller to medium Dimensions in the complete section and parts up to large thicknesses and dimensions in the subsequent cut, from.
Die erfindungsgemäßen Vorrichtungen haben einen einfachen und robusten Aufbau. Im Falle des Einsatzes des Folgeschnitts ist mindestens ein entgegen der Schneidrichtung wirkender, der Schneidstufe vorgeordneter Prägestempel zum negativen Vorformen eines an den erwarteten Kanteneinzug angepassten Materialvolumens an der Einzugsseite vorgesehen, wobei der Prägestempel an seiner Aktivseite eine Kontur bzw. einen Vorformwinkel aufweist, die bzw. der der Geometrie des erwarteten Kanteneinzugs zuzüglich einer Zugabe entspricht. Für den Komplettschnitt ist mindestens ein entgegen der Schneidrichtung wirkender, der Schneidstufe zugeordneter Auswerfer zum negativen Vorformen eines an den erwarteten Kanteneinzug angepassten Materialvolumens an der Einzugsseite vorgesehen, wobei der Auswerfer an seiner Aktivseite eine Kontur bzw. einen Vorformwinkel aufweist, die bzw. der der Geometrie des erwarteten Kanteneinzugs zuzüglich einer Zugabe angepasst ist, wobei der Auswerfer den vorgeformten Bereich beim Schneiden abstützt.The devices according to the invention have a simple and robust construction. In the case of the use of the subsequent cut at least one counter to the cutting direction, the cutting stage upstream punch for negative preforming adapted to the expected edge feed volume of material on the feed side is provided, the die has on its active side a contour or a preforming angle, or which corresponds to the geometry of the expected edge indent plus an addition. For the complete cut, at least one ejector, which counteracts the cutting direction and is assigned to the cutting stage, is provided for negative preforming of a material volume adapted to the expected edge feed on the feed side, wherein the ejector has on its active side a contour or a preform angle which or of the geometry the expected edge indentation plus an addition is adjusted, wherein the ejector supports the preformed area during cutting.
Die Vorformwinkel für den Prägestempel bei Folgeschnitt und den Auswerfer beim Komplettschnitt betragen etwa zwischen 20° und 40°.The preforming angles for the embossing punch in the case of a subsequent cut and the ejector in the case of the complete cut are approximately between 20 ° and 40 °.
Weitere Vorteile und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung unter Bezugnahme auf die beigefügten Zeichnungen.Further advantages and details will become apparent from the following description with reference to the accompanying drawings.
Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden.The invention will be explained in more detail below using an exemplary embodiment.
Die
Die Vorstufe wird gebildet durch einen im Unterteil 2 geführten als Vorformelement V ausgebildeten Prägestempel 13, der auf seiner Aktivseite 14 einen zuvor durch eine virtuelle Umformsimulation bestimmten Vorformwinkel α aufweist und mit einer Kontur 15 versehen ist, die der Geometrie des erwarteten Einzugs mit einer aus Erfahrungswerten resultierenden Zugabe entspricht. Das Vorformen des zwischen Ober- und Teil 1 bzw. 2 eingeklemmten Bandstreifens erfolgt durch den Prägestempel 13, dessen Wirkrichtung entgegen der Schneidrichtung SR des Schneidstempels 5 verläuft. Der Prägestempel 13 verformt bei seiner Vorschubbewegung den Bandstreifen 10 soweit, dass sich die Kontur 15 der Aktivseite 14 des Prägestempels mit seinem Vorformwinkel α in das Material des Bandstreifens um einen an die Geometrie des Einzugs angepassten Betrag hineinbewegt und eine Verformung des Bandstreifens 10 auf der Einzugsseite bewirkt, die dem Volumen des erwarteten Einzugs entspricht.
Die Prozessparameter für das Vorformen, beispielsweise die Geometrie, d.h. die Einzugshöhe und Einzugsbreite, und das Werkstoffvolumen, d.h. Einzugsvolumen, wird in Abhängigkeit von Materialart, Form und Geometrie des Werkstücks durch eine virtuelle Umformsimulation bestimmt, in der der Werkstofffluss im Umformprozess dargestellt, Dehnungen und Vergleichsspannungen analysiert werden, um festzustellen, ob die Formänderung machbar und die Belastungen durch die Werkzeugelemente getragen werden können. Die Prozessparameter für das Vorformen können aber auch am realen Feinschneidteil durch individuelle Vermessung der Einzugshöhe, Einzugsbreite und Bestimmung des Einzugsvolumens ermittelt werden. Dazu bedarf es eine Reihe von Versuchen und deren Auswertung, um auf dieser Grundlage den Prägestempel 13 entsprechend auslegen zu können.The process parameters for preforming, such as the geometry, i. the pull-in height and pull-in width, and the material volume, i. Feeding volume is determined by a virtual forming simulation, depending on the material type, shape and geometry of the workpiece, in which the flow of material in the forming process is shown, strains and reference stresses are analyzed to determine whether the deformation can be made and the loads borne by the tool elements. However, the process parameters for the preforming can also be determined on the real fineblanking part by individual measurement of the pull-in height, pull-in width and determination of the feed volume. This requires a series of tests and their evaluation in order to be able to interpret the
