Description

Die Erfindung betrifft ein Verfahren zum Herstellen von Stanzteilen in einem Werkzeug, insbesondere einem Feinschneidwerkzeug, mittels zumindest einem Stempel, mit dem das Stanzteil aus einem Materialstreifen herausgedrückt wird, wobei das Stanzteil nach dem Herausdrücken aus dem Materialstreifen von diesem zu einem Austrag geschoben wird.The invention relates to a method for producing stamped parts in a tool, in particular a fineblanking tool, by means of at least one stamp, with which the stamped part is pressed out of a strip of material, wherein the stamped part is pushed out of the material strip from this to a discharge after the pressing out.

Stand der TechnikState of the art

Stanzteile werden heute in der Regel auf Stanzmaschinen in einem Werkzeug hergestellt, welches aus einem oberen und einem unteren Werkzeugteil besteht, zwischen denen ein Materialstreifen eingeklemmt wird. Entsprechende Stempel drücken dann das Stanzteil aus dem Materialstreifen. Beim Öffnen des Werkzeuges werden diese Stanzteile ausgeworfen.Stamped parts are usually produced today on punching machines in a tool, which consists of an upper and a lower tool part, between which a strip of material is clamped. Corresponding stamps then press the stamped part out of the material strip. When opening the tool these punched parts are ejected.

Eine Unterart des Stanzens ist das Feinschneiden. Eine entsprechende Feinschneidvorrichtung ist bspw. in der DE 35 76 129 A1 gezeigt. Ein Werkzeug zum Feinschneiden findet sich in der DE 197 51 238 A1 .One subtype of punching is fineblanking. A corresponding fine-cutting device is, for example, in the DE 35 76 129 A1 shown. A fineblanking tool can be found in the DE 197 51 238 A1 ,

Probleme bereitet unter anderem das Abführen der Stanzteile. Bspw. geschieht dies durch Ausblasen oder mittels spezieller Entnahmevorrichtungen. Meist ist die Entnahme unsortiert oder sehr aufwendig.Problems include the removal of the stamped parts. For example. this is done by blowing or by special removal devices. Most of the removal is unsorted or very expensive.

In manchen Fällen wird das Stanzteil auch wieder in den Materialstreifen zurückgedrückt und mit dem Materialstreifen ausgetragen. Dieses Zurückdrücken hat aber den Nachteil, dass das Stanzteil oft Beschädigungen an den Funktionsflächen erleidet.In some cases, the stamped part is also pushed back into the strip of material and discharged with the strip of material. However, this pressing back has the disadvantage that the stamped part often suffers damage to the functional surfaces.

Aus der JP 02 046936 A ist bekannt, aus einem Materialstreifen hinter dem Stanzteil zwei Vorsprünge herauszudrücken, die das Stanzteil zu einem Austrag mitnehmen. Ähnlich wird bei der US-A-2790499 hinter dem Stanzteil ein brückenartiger Ausschnitt herausgedrückt, wobei in diesem Bereich auch der Materialstreifen nach dem Stanzteil angehoben wird, und dieser brückenartige Ausschnitt das Stanzteil mit sich zu einer Austragsschräge führt.From the JP 02 046936 A It is known to push out of a strip of material behind the stamped part two projections, which take the stamped part to a discharge. Similarly, at the US-A-2790499 behind the punched part, a bridge-like cutout pushed out, in which area the material strip is lifted after the stamped part, and this bridge-like cutout leads the stamped part with it to a Austragsschräge.

Aufgabetask

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der oben genannten Art zu entwickeln, mit denen das Stanzteil einfach, sortiert und beschädigungsfrei ausgetragen werden kann.The present invention has for its object to develop a method and an apparatus of the type mentioned above, with which the stamped part can be easily, sorted and discharged without damage.

Lösung der AufgabeSolution of the task

Zur Lösung der Aufgabe führt, dass am Stanzteil eine vorstehende Partie genutzt oder zusätzlich ausgeformt wird, an der der Materialstreifen das Stanzteil mitnimmt.To achieve the object results in that a projecting batch is used or additionally formed on the stamped part, at which the material strip entrains the stamped part.

In einem bevorzugten Ausführungsbeispiel arbeitetet der Stempel mit einem Gegenhalter in einer Schneidplatte zusammen, wobei beim Ausstanzen des Stanzteils diese gegen die Kraft des Gegenhalters in die Schneidplatte gedrückt wird. Wird nun die Schneidplatte von dem Stempel entfernt, so drückt der Gegenhalter das Stanzteil wieder aus der Schneidplatte heraus, so dass dieses bevorzugt auf der Oberfläche der Schneidplatte zu liegen kommt. Auf dieser Oberfläche wird das Stanzteil dann mittels des Materialstreifens bis zum Austrag entlanggeschoben.In a preferred embodiment, the punch cooperates with a counter-holder in a cutting plate, wherein during punching of the stamped part, this is pressed against the force of the counter-holder in the cutting plate. If now the cutting plate is removed from the punch, then the counter-holder pushes the punched part out of the cutting plate again, so that it preferably comes to lie on the surface of the cutting plate. On this surface, the stamped part is then pushed along by means of the material strip to the discharge.

Damit das Stanzteil ohne Störung durch den Materialstreifen an die Oberfläche der Schneidplatte gebracht werden kann, muss der Materialstreifen relativ von der Schneidplatte abgehoben werden. Zu diesem Zweck ist eine Einrichtung vorgesehen, welche die relative Lage des Materialstreifens gegenüber der Schneidplatte und, sofern vorgesehen, auch gegenüber der Pressplatte, in welcher der Stempel geführt wird, bestimmt wird. Für diese Einrichtung können eine Vielzahl von Ausführungsbeispielen vorgesehen werden. In einem einfachen Ausführungsbeispiel werden sich die Streifenführungen zunutze gemacht, die bereits nach dem Stand der Technik den Materialstreifen zwischen sich halten und ihn durch das Stanzwerkzeug hindurchführen. Diese Streifenführungen werden nun so ausgestaltet, dass sie eine Aufnahme ausbilden, mit der es möglich ist, den Materialstreifen relativ gegenüber der Schneidplatte und/oder der Pressplatte zu bewegen. Zu diesem Zweck dürfte es ratsam sein, dass diese Aufnahme parallel zum Stempel bzw. zum Gegenhalter bewegbar ist.So that the stamped part can be brought to the surface of the cutting plate without interference by the strip of material, the strip of material must be lifted off the cutting plate relatively. For this purpose, a device is provided which determines the relative position of the material strip relative to the cutting plate and, if provided, also with respect to the press plate in which the punch is guided. For this device, a variety of embodiments may be provided. In a simple embodiment, the strip guides are made use of, which already hold the material strip between the prior art and pass it through the punch. These strip guides are now designed to form a receptacle with which it is possible to move the material strip relative to the cutting plate and / or the pressing plate. For this purpose, it may be advisable that this recording is movable parallel to the punch or the counter-holder.

Durch das Abheben des Materialstreifens auf einen definierten Abstand zur Schneidplatte hin wird gewährleistet, dass das Stanzteil aus der Schneidplatte ausgestossen werden kann und unterhalb des Materialstreifens auf der Oberfläche der Schneidplatte aufliegt.By lifting the strip of material to a defined distance from the cutting plate, it is ensured that the stamped part can be ejected from the cutting plate and rests on the surface of the cutting plate below the strip of material.

Damit nun der Materialstreifen beim Weitertransport auch das Stanzteil vor sich herschieben kann, ist es notwendig, dass ein entsprechendes Widerlager am Stanzteil vorhanden ist. D. h. , dem Stanzteil wird eine Erhöhung angeformt, auf die eine Steuerkante am Materialstreifen auftrifft.In order for the material strip to be able to push the stamped part in front of it during further transport, it is necessary for a corresponding abutment to be present on the stamped part. Ie. , The punched part is formed an increase, which is incident on a control edge on the material strip.

Als Austrag bietet sich eine einfache Ausfallschräge an, die in der Tränsportrichtung des Materialstreifen vorgehen ist. Hierdurch wird der gesamte Stanzvorgang nicht behindert.As a discharge offers a simple default slope, which is in the Tränsportrichtung the strip of material proceed. As a result, the entire punching process is not hindered.

In dem entsprechenden erfindungsgemässen Werkzeug können selbstverständlich auch noch weitere Innenstempel vorhanden sein, mit denen Vorstufen- oder Innenformvorgänge durchgeführt werden. Dies geschieht in paralleler Richtung zum Stempel, d. h., in der Regel senkrecht zur Vorschubrichtung des Materialstreifens.Of course, further inner punches may also be present in the corresponding tool according to the invention with which precursor or internal forming operations are carried out. This happens in the direction parallel to the stamp, d. h., Usually perpendicular to the feed direction of the strip of material.

Das erfindungsgemässe Verfahren und die entsprechende Vorrichtung haben den grossen Vorteil, dass die Stanzteile, insbesondere Feinschneidteile, separiert von den Innenform- und Vorstufenabfällen den Werkzeugraum verlassen. Dies geschieht beschädigungsfrei, da nicht die Gefahr besteht, dass sie zwischen den beiden Werkzeughälften verbleiben und bei einem folgenden Stanzvorgang beschädigt werden.The method according to the invention and the corresponding device have the great advantage that the stamped parts, in particular fineblanked parts, leave the tool space separated from the inner mold and precursor wastes. This is done without damage, since there is no risk that they remain between the two mold halves and are damaged in a subsequent punching operation.

Für das Ausbringen der Stanzteile sind keine zusätzlichen Handlingskomponenten notwendig. Auf Grund des zwangsweisen Abtransports der Stanzteile mit dem Materialstreifen kann der Stösselweg der Presse insgesamt reduziert werden. Hierdurch ist es möglich, die Taktzahl erheblich zu steigern.For the removal of the stamped parts no additional handling components are necessary. Due to the forced removal of the stamped parts with the strip of material of the Stösselweg the press can be reduced overall. This makes it possible to increase the number of cycles significantly.

Hierdurch wird im Bereich des Bolzenabschnitts 17 zwischen Kolben 16 und Führungskolben 18 eine Aufnahme 19 gebildet, in welcher der Materialstreifen 7 geführt und gehalten ist.The material strip 7 is further associated with a device 15 for lifting the material strip 7. This has a in the press plate. 4 guided piston 16, which is assigned a bolt portion 17 with a smaller diameter and then a guide piston 18 with a larger diameter. In this way, a receptacle 19 is formed in the region of the bolt portion 17 between the piston 16 and the guide piston 18, in which the material strip 7 is guided and held.

Die Funktionsweise der vorliegenden Erfindung ist folgende:The operation of the present invention is as follows:

Der Materialstreifen 7 wird, geführt in der Einrichtung 15 zum Abheben des Materialstreifens 7, zwischen das obere und das untere Werkzeugteil 2 bzw. 3 eingebracht. Das Werkzeug P wird geschlossen, wobei der Führungskolben 18 gegen einen federgelagerten Gegenkolben 20 in eine Führungsbohrung 21 in die Schneidplatte 10 eintaucht.The strip of material 7, guided in the device 15 for lifting the strip of material 7, between the upper and the lower tool part 2 and 3 is introduced. The tool P is closed, wherein the guide piston 18 is immersed against a spring-loaded counter-piston 20 in a guide bore 21 in the cutting plate 10.

Der Innenformstempel 6 schneidet aus dem Materialstreifen 7 den Abfall 8.1 aus, der durch die Bohrung 9 nach unten wegfällt.The inner mold punch 6 cuts out of the strip of material 7 from the waste 8.1, which falls away through the hole 9 down.

Mit dem Stempel 5 wird das Stanzteil 1.1 aus dem Materialstreifen 7 herausgeschnitten, wobei Druckstempel 13 und Gegenstempel 14 so eingestellt sind, dass ein nach oben vorstehendes Stützteil 22 an dem Stanzteil 1.1 ausgebildet wird.With the punch 5, the stamped part 1.1 is cut out of the strip of material 7, wherein plunger 13 and counter punch 14 are set so that an upwardly projecting support member 22 is formed on the stamped part 1.1.

Der Innenformstempel 6.2 wirft den Abfall 8.2 durch die Bohrung 12 in dem Stempel 5 aus.The inner forming die 6.2 ejects the waste 8.2 through the bore 12 in the punch 5.

Nunmehr wird das Werkzeug P, wie in Figur 2 dargestellt, geöffnet, wobei die Schneidplatte 10 weg von der Pressplatte 4 läuft. Dieser Bewegung folgt teilweise auch der Kolben 16, so dass ein Abheben des Materialstreifens 7 von der Pressplatte 4 erfolgt.
