Bauteilen aus einer Platine aus Metall mit einem Ziehstempel und einer Matrize, wobei der Ziehstempel eine Schneidkante zum Beschneiden der Platine während des Ziehvorganges aufweist und in der Matrize eine Einlaufkontur vorgesehen ist. Darüber hinaus betrifft die Erfindung ein Verfahren zum Ziehen einer Platine unter Verwendung der erfindungsgemäßen Vorrichtung sowie eine erfindungsgemäße Verwendung des Components of a metal circuit board with a punch and a die, wherein the drawing punch has a cutting edge for trimming the board during the drawing process and in the die an inlet contour is provided. Moreover, the invention relates to a method for drawing a circuit board using the device according to the invention and a use of the invention
Verfahrens . Procedure.
Es ist bekannt, Platinen aus einem Metall, insbesondere Stahl oder Aluminium zu ziehen und während des Ziehvorgangs gleichzeitig ein Besäumen bzw. Beschneiden des gezogenen Teils durchzuführen. So ist beispielsweise aus der It is known to draw boards made of a metal, in particular steel or aluminum and at the same time carry out a trimming or trimming of the drawn part during the drawing process. For example, from the
japanischen Patentanmeldung JP 01034525 bekannt, einen Japanese Patent Application JP 01034525, a
Ziehstempel mit einer Schneidkante zu versehen, welcher die Platine während des Ziehvorgang beschneidet, so dass ein flanschfreies Bauteil hergestellt wird. Es hat sich aber herausgestellt, dass bei dem bekannten Verfahren die Drawing punch to be provided with a cutting edge, which cuts the board during the drawing process, so that a flange-free component is produced. However, it has been found that in the known method the
Schneidkräfte sehr hoch sind und ein sauberer Beschnitt der Platine aufgrund der hohen Schneidkräfte nicht immer Cutting forces are very high and a clean trimming of the board is not always due to the high cutting forces
sichergestellt werden kann. Darüber hinaus ist vom can be ensured. In addition, from the
konventionellen Beschneiden von Platinen bekannt, die Conventional trimming of printed circuit boards is known
Schneidkante bezogen auf die Blechebene schräg auszubilden, so dass beim Absenken der Schneidkante auf die Platine der Schneideingriff mit zunehmender Bewegung der Schneidkante entlang der Schneidlinie wandert, bis die vollständige Trennung erreicht ist. Die Schneidkante des Ziehstempels wird aber gleichzeitig dazu verwendet, die Kontur des gezogenen Bauteils mitzubestimmen und/oder das Bauteil beispielsweise zu stauchen. Eine Schrägstellung dieser Schneidkante ist daher in der Regel nicht möglich. Eine Verringerung der Cutting edge with respect to the sheet plane obliquely, so that when lowering the cutting edge on the board of the cutting engagement with increasing movement of the cutting edge along the cutting line moves until the complete Separation is achieved. However, the cutting edge of the drawing punch is simultaneously used to co-determine the contour of the drawn component and / or to compress the component, for example. An inclination of this cutting edge is therefore not possible in the rule. A reduction in the
Schneidkräfte ohne Veränderung der Kontur des gezogenen Cutting forces without changing the contour of the drawn
Bauteils ist daher nicht ohne weiteres möglich. Component is therefore not readily possible.
Ferner ist bekannt, die Matrize einer Vorrichtung zum Ziehen von Platinen mit einer Einlaufkontur zu versehen. Die It is also known to provide the die of a device for drawing boards with an inlet contour. The
Einlaufkontur ist der Bereich der Matrize, in welchem die eigentliche Formvertiefung der Matrize in die Zarge übergeht. Als Einlaufkontur wird zur Erleichterung des Ziehvorganges ein möglichst großer Radius vorgesehen, so dass der  Infeed contour is the area of the die in which the actual mold cavity of the die merges into the frame. As Einlaufkontur the largest possible radius is provided to facilitate the drawing process, so that the
Materialfluss der Platine nicht über einen engen Radius erfolgen muss. Material flow of the board must not be made over a narrow radius.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren zur Verfügung zu stellen, mit welchem die Schneidkräfte beim integrierten Ziehen und Beschneiden verringert werden können, ohne die Kontur des Bauteils zu beeinflussen. Darüber hinaus liegt der On this basis, the object of the invention is to provide a device and a method with which the cutting forces during integrated drawing and trimming can be reduced without influencing the contour of the component. In addition, lies the
vorliegenden Erfindung die Aufgabe zugrunde, ein present invention, the object of a
entsprechendes Herstellverfahren zur Verfügung zu stellen. to provide appropriate manufacturing process.
Gemäß einer ersten Lehre der vorliegenden Erfindung wird die oben aufgezeigte Aufgabe dadurch gelöst, dass die According to a first teaching of the present invention, the above-mentioned object is achieved in that the
Einlaufkontur der Matrize derart ausgebildet ist, dass die Schneidkante und die Einlaufkontur in der Ziehstempelposition zu Beginn des Schneidvorgangs entlang der Schneidlinie nur bereichsweise im Schneideingriff stehen. Die Einlaufkontur der Matrize, welche dazu dient, den Infeed contour of the die is formed such that the cutting edge and the inlet contour in the Ziehstempelposition are only partially in cutting engagement at the beginning of the cutting along the cutting line. The inlet contour of the die, which serves to the
Ziehvorgang zu erleichtern, ist in der Regel als größerer Radius ausgebildet, welcher üblicherweise entlang der To facilitate drawing process is usually formed as a larger radius, which is usually along the
Schneidlinie identisch ausgebildet ist, um das Ziehen entlang der gesamten Einlaufrundung gleichmäßig zu erleichtern. Bei dieser Ausprägung der Einlaufkontur findet der Cutting line is formed identically, to facilitate the pulling along the entire Einlaufrundung evenly. In this expression of the inlet contour of the finds
Schneideingriff der Schneidkante entlang der gesamten Cutting engagement of the cutting edge along the entire
Schneidlinie gleichzeitig statt. Demgegenüber ist die Cutting line at the same time. In contrast, the
erfindungsgemäße Einlaufkontur derart ausgebildet, dass die Schneidkante des Ziehstempels zu Beginn des Schneidprozesses nur einen bereichsweisen Schneideingriff der Schneidkante erzeugt, so dass nicht die gesamte Schneidlinie gleichzeitig über die Schneidkante im Schneideingriff steht. Die inlet contour according to the invention designed such that the cutting edge of the drawing punch at the beginning of the cutting process generates only a partial cutting engagement of the cutting edge, so that not the entire cutting line is simultaneously in cutting engagement on the cutting edge. The
Minimalvoraussetzung für einen sauberen Beschnitt der Platine besteht darin, dass die Einlaufkontur der Matrize den The minimum requirement for a clean trimming of the board is that the inlet contour of the die
Schneideingriff, bezogen auf die Ziehstempelposition in der der Schneidvorgang beginnt, an mindestens einem Punkt  Cutting engagement, based on the drawing punch position in which the cutting process begins, at least one point
bereitstellt. Von diesem Punkt ausgehend wandert der provides. Starting from this point migrates the
Schneideingriff der Schneidkante bei weiterer Abwärtsbewegung entlang der Schneidlinie bis es zur vollständigen Trennung der gezogenen Platine von dem Beschnitt kommt. Die Cutting engagement of the cutting edge on further downward movement along the cutting line until it comes to complete separation of the drawn board from the trim. The
Einlaufkontur kann dies beispielsweise durch die Verwendung unterschiedlicher Radien entlang der Schneidlinie Infeed contour, this can for example by the use of different radii along the cutting line
gewährleisten, so dass an verschiedenen Positionen entlang der Schneidlinie die Einlaufkontur in unterschiedlichen Höhen relativ zum Boden der Matrize bereits die endgültige Form der Matrize aufweist und so den Schneideingriff nur bereichs- oder punktweise zulässt. Durch den daraus resultierenden, entlang der Schneidlinie wandernden Schneideingriff werden die Schneidkräfte und auch der Verschleiß der Vorrichtung, insbesondere der Schneidkante deutlich verringert. Bevorzugt ist die Vorrichtung zum Ziehen von Platinen aus Stahl ausgelegt. Hierzu müssen beispielsweise spezifische Stahlgüten an der Schneidkante vorgesehen und/oder die ensure that at various positions along the cutting line, the inlet contour at different heights relative to the bottom of the die already has the final shape of the die and thus allows the cutting engagement only in areas or points. Due to the resulting, along the cutting line migratory cutting engagement, the cutting forces and wear of the device, in particular the cutting edge are significantly reduced. Preferably, the device is designed for pulling steel blanks. For this purpose, for example, specific steel grades must be provided on the cutting edge and / or the
Abmessungen der Matrize und des Ziehstempels auf das Dimensions of the die and the drawing punch on the
Fließverhalten des umzuformenden Werkstoffs angepasst werden. Flow behavior of the material to be formed are adjusted.
Gemäß einer ersten Ausgestaltung der erfindungsgemäßen According to a first embodiment of the invention
Vorrichtung ist die Schneidkante des Ziehstempels Device is the cutting edge of the drawing punch
gleichzeitig zur Formung der Fertigkontur des Bauteils ausgebildet und verläuft optional in einer Ebene senkrecht zur Ziehbewegung des Ziehstempels. Gegebenenfalls wird die Fertigkontur des Bauteils auch durch die Schneidkante des Ziehstempels gestaucht. Da erfindungsgemäß die Ausbildung der Schneidkante nahezu unabhängig von dem zu realisierenden Schneideingriff geformt werden kann, kann diese ohne Probleme an die jeweilige Bauteilgeometrie angepasst werden und zur Formgebung des gezogenen Bauteils, insbesondere der formed simultaneously to form the finished contour of the component and optionally extends in a plane perpendicular to the pulling movement of the drawing punch. Optionally, the finished contour of the component is also compressed by the cutting edge of the drawing punch. Since according to the invention the formation of the cutting edge can be formed almost independently of the cutting engagement to be realized, it can be adapted without problems to the respective component geometry and for shaping the drawn component, in particular the
Stirnfläche der Zargen eines gezogenen Bauteils genutzt werden. Dies wird dadurch erreicht, dass die Einlaufkontur der Matrize die Funktion des wandernden Schneideingriffs der Schneidkante gewährleistet. Eine besonders einfache End face of the frames of a drawn component can be used. This is achieved in that the inlet contour of the die ensures the function of the wandering cutting engagement of the cutting edge. A particularly simple one
Schneidkante kann dann dadurch bereitgestellt werden, dass die Schneidkante senkrecht zur Ziehbewegung des Ziehstempels in einer Ebene verläuft. Beim Ausformen des gezogenen Cutting edge can then be provided by the fact that the cutting edge is perpendicular to the pulling movement of the drawing punch in a plane. When molding the drawn
Bauteils ergibt sich dadurch ebenfalls ein ebenes Bauteil im Bereich der Formgebung der Schneidkante bzw. der Stirnflächen der Zargen des Bauteils. Component thus also results in a planar component in the region of the shaping of the cutting edge and the end faces of the frames of the component.
Einen gleichmäßigen Schneidvorgang gewährleistet eine weitere Ausführungsform der erfindungsgemäßen Vorrichtung dadurch, dass die Einlaufkontur entlang der Schneidelinie variierend ausgebildet ist. „Variierend" im Sinne der vorliegenden Erfindung bedeutet, dass der Schneidvorgang bei Veränderung der Position des Ziehstempels nach dem Beginn des A uniform cutting process is ensured by a further embodiment of the device according to the invention in that the inlet contour along the cutting line is formed varying. "Varying" in the sense of the present Invention means that the cutting operation when changing the position of the drawing punch after the beginning of
Schneidvorgangs entlang der Schneidlinie wandert, bis die vollständige Trennung vom Beschnitt erreicht wird. Gemäß einer weiteren Ausführungsform ist die Einlaufkontur in Cutting process along the cutting line moves until complete separation from the trimming is achieved. According to a further embodiment, the inlet contour is in
Richtung der Schneidlinie stufenförmig ausgebildet, so dass jeweils Bereiche der Schneidlinie simultan mit der  Formed in the direction of the cutting line step-shaped, so that in each case portions of the cutting line simultaneously with the
Schneidkante im Schneideingriff stehen und gleichzeitig abgetrennt werden. Cutting edge are in cutting engagement and disconnected simultaneously.
Weist die Einlaufkontur gemäß einer weiteren Ausführungsform der erfindungsgemäßen Vorrichtung einen zahnartigen oder wellenartigen Verlauf entlang der Schneidlinie auf, kann der Schneideingriff gleichzeitig an verschiedenen Punkten der Schneidlinie erfolgen und ein fortlaufender Beschnitt an mehreren Stellen der Schneidlinie gleichzeitig erfolgen. If the inlet contour has a tooth-like or wave-like course along the cutting line according to a further embodiment of the device according to the invention, the cutting engagement can take place simultaneously at different points of the cutting line and a continuous trimming at several points of the cutting line take place simultaneously.
Aufgrund der Form der Einlaufkontur weist diese entlang der Schneidlinie mindestens einen Punkt auf, in welchem der Due to the shape of the inlet contour this has along the cutting line at least one point in which the
Schneidvorgang beginnt, d.h. an welchem die Einlaufkontur bezogen auf die Ziehstempelposition zuerst in die Cutting process begins, i. at which the inlet contour based on the drawing punch position first in the
Matrizenform übergeht. Matrizenform goes over.
Von dieser Position aus setzt sich der Beschnitt der Platine fortlaufend in Richtung tiefster Stelle der Einlaufkontur fort. Bei einem Mehrfacheingriff greift die Schneidkante des Ziehstempels gleichzeitig an mehreren Punkten in die gezogene Platine ein und beginnt den Schneidvorgang. Erfindungsgemäß beträgt der Schneidwinkel zwischen From this position, the trimming of the board continues continuously in the direction of the lowest point of the inlet contour. In a multiple engagement, the cutting edge of the drawing punch simultaneously engages the drawn board at several points and begins the cutting process. According to the invention, the cutting angle is between
Schneidkante und der Einlaufkontur 1° bis 5°, um gute  Cutting edge and the inlet contour 1 ° to 5 ° to good
Schnittergebnisse zu erzielen. Gemäß einer zweiten Lehre der vorliegenden Erfindung wird die oben aufgezeigte Aufgabe verfahrensmäßig dadurch gelöst, dass die Schneidkante des Ziehstempels und die Einlaufkontur der Matrize in der Ziehstempelposition zu Beginn des To achieve cutting results. According to a second teaching of the present invention, the above-described object is procedurally achieved in that the cutting edge of the drawing punch and the inlet contour of the die in the drawing punch position at the beginning of
Schneidvorgangs entlang der Schneidlinie nur bereichsweise und mindestens an einem Punkt der Schneidlinie im  Cutting process along the cutting line only partially and at least at one point of the cutting line in
Schneideingriff stehen und die Platine durch die Bewegung des Ziehstempels in die Matrize ausgehend von dem Cutting and stand the board by the movement of the drawing punch in the die starting from the
Schneideingriffspunkt oder den Schneideingriffspunkten entlang der Schneidlinie fortlaufend geschnitten wird. Cutting engagement point or the cutting engagement points along the cutting line is cut continuously.
Wie bereits zuvor ausgeführt, wird durch das erfindungsgemäße Verfahren nicht nur ein sauberer Beschnitt der Platine während des Ziehvorgangs erreicht, sondern es werden auch effektiv die Schneidkräfte gesenkt, so dass der Verschleiß an der Schneidkante verringert und der Schneidvorgang deutlich harmonisiert wird. Insgesamt steht ein verbessertes Verfahren zur Verfügung, welches für das Ziehen und gleichzeitige As already stated above, the method according to the invention not only achieves a clean trimming of the board during the drawing process, but also effectively reduces the cutting forces, so that the wear on the cutting edge is reduced and the cutting process is clearly harmonized. Overall, there is an improved method available for pulling and simultaneously
Beschneiden hoher Stückzahlen an Platinen geeignet ist. Cropping high volumes of printed circuit boards is appropriate.
Das erfindungsgemäße Verfahren kann dadurch weiterverbessert werden, dass die Schneidkante des Ziehstempels bei Erreichen dessen Endposition die Kontur des Bauteils im Bereich der Schnittkante ausformt und/oder eine Stauchung des Bauteils durchführt. Da bereits mit der Einlaufkontur der Matrize die unterschiedlichen Schneideingriffspunkte festgelegt werden, kann die Ausbildung der Schneidkante darauf ausgelegt werden, dass die Kontur des Bauteils im Bereich der Schnittkante, beispielsweise bei einem napfartigen Bauteil die Stirnkante der Zargen des Bauteils, ausgeformt wird und zwar unabhängig von der Realisierung eines Fortlaufens des Beschnittes während des Ziehvorgangs. Vorzugsweise werden die Stirnflächen der Zargen des gezogenen Bauteils flach und in einer Ebene geformt, um eine Anbindungsmöglichkeit des The inventive method can be further improved by the fact that the cutting edge of the drawing punch forms the contour of the component in the region of the cutting edge when reaching its end position and / or performs a compression of the component. Since the different cutting engagement points are already determined with the inlet contour of the die, the design of the cutting edge can be designed so that the contour of the component in the region of the cutting edge, for example in a cup-like component, the front edge of the frame of the component is formed, regardless of the realization of a continuation of the trimming during the drawing process. Preferably, the end faces of the frames of the drawn component are flat and formed in a plane to a connection possibility of the
Bauteils über die Stirnflächen der Zargen zu gewährleisten. Component over the end faces of the frames to ensure.
Schließlich ist die Verwendung des erfindungsgemäßen Finally, the use of the invention
Verfahrens vorteilhaft für die Herstellung von gezogenen Bauteilen aus Stahl für Kraftfahrzeuge. Regelmäßig werden bei Kraftfahrzeugteilen hohe Stückzahlen mit geringen Kosten aber hoher Qualität gefordert. Die Verwendung des Method advantageous for the production of drawn steel components for motor vehicles. Regularly high volumes are required at low cost but high quality in motor vehicle parts. The use of the
erfindungsgemäßen Verfahrens zur Herstellung von Bauteilen für Kraftfahrzeuge kann nicht nur in einem Arbeitsschritt Bauteile mit hoher Qualität, sondern aufgrund des inventive method for the production of components for motor vehicles can not only in one step components with high quality, but due to the
verringerten Verschleißes der erfindungsgemäßen Vorrichtung auch hohe Stückzahlen dieser Bauteile ermöglichen. reduced wear of the device according to the invention also allow high volumes of these components.

Die Schneidlinie 7, welche den Schneideingriff zwischen Schneidkante und Einlaufkontur der Matrize markiert, weist einen Höhenverlauf auf. In dem vorliegenden Symmetryeachse the contour of the die 3 has an eccentricity. The cutting line 7, which marks the cutting engagement between cutting edge and inlet contour of the die, has a height profile. In the present
Ausführungsbeispiel findet der Schneideingriff der Embodiment finds the cutting engagement of
Schneidkante 4 ab einer Position des Ziehstempels 2 zunächst im Punkt 7a statt, da hier die Einlaufkontur bereits bei geringerer Ziehtiefe in die Endkontur 8 der Matrize 3 Cutting edge 4 from a position of the drawing punch 2 initially at point 7a instead, since here the inlet contour even at a lower depth of draw into the final contour 8 of the die. 3
übergeht. Wird der Ziehstempel 2 weiter in Richtung Matrize 3 bewegt, schneidet die Schneidkante 4 des Ziehstempels 2 beginnend vom Schneidlinienpunkt 7a die gezogene Platine 1 fortlaufend, bis der Schnitt am Punkt 7b die vollständige Trennung des gezogenen Teils der Platine la vom Beschnitt lb vollzogen hat. Dies gewährleistet, dass der Schneidvorgang während des Ziehens lediglich bereichsweise und mindestens an einem Punkt 7a eingeleitet wird. Das Beschneiden der Platine während des Ziehens erfordert dann keine hohen Kräfte mehr, da nicht die vollständige Schneidlinie im Schneideingriff der Schneidkante 4 und der Matrize 3 steht. passes. If the drawing punch 2 is moved further in the direction of the die 3, the cutting edge 4 of the drawing punch 2 continuously cuts the drawn blank 1 starting from the cutting line point 7a until the cut at point 7b has completed the complete separation of the drawn part of the blank la from the cut lb. This ensures that the cutting process during the drawing is introduced only partially and at least at one point 7a. Trimming the board while it is being pulled does not require high forces anymore, because not the complete cutting line in the cutting engagement of the cutting edge 4 and the die 3 is.
Die vollständige Trennung von dem gezogenen Teil der Platine la und dem Beschnitt lb muss spätestens dann erfolgt sein, wenn der Ziehstempel 2 seine Endposition erreicht hat. The complete separation of the drawn part of the board la and the trimming lb must have taken place at the latest when the drawing punch 2 has reached its end position.
Vorzugsweise wird der Beschnitt aber vor Erreichen der Preferably, the trimming but before reaching the
Endposition des Ziehstempels 2 durchgeführt, um über die Schneidkante 4 die Stirnflächen der Zargen des fertigen End position of the drawing punch 2 performed to over the cutting edge 4, the end faces of the frames of the finished
Bauteils auszuformen und gegebenenfalls zu stauchen. Form part and compress if necessary.
Die Ausbildung der Matrize des Ausführungsbeispiels aus Fig. 1 zeigt in einer perspektivischen Darstellung die Fig. 2. Die Matrize 3 weist eine Einlaufkontur 5 auf, welche in Bezug auf die Ziehrichtung in unterschiedlichen Höhen in die Endkontur 8 der Matrize 3 übergeht. In der Fig. 2 sind diese Punkte mit 5a und 5b gekennzeichnet. Im Punkt 5a geht die Endkontur 5 der Matrize 3 beispielsweise bereits bei geringerer Ziehtiefe des Ziehstempels 2 in die Endkontur 8 der Matrize 3 über, so dass der Schneideingriff zwischen Schneidkante 4 und Platine 1 bereits bei geringerer Ziehtiefe erfolgt. Der Schnitt setzt sich dann vom Punkt 5a fort, bis er umlaufend in beide The die of the embodiment of FIG. 1 shows in a perspective view of FIG. 2. The die 3 has an inlet contour 5, which merges with respect to the pulling direction at different heights in the final contour 8 of the die 3. In FIG. 2, these points are labeled 5a and 5b. In point 5a, the final contour 5 of the die 3, for example, already at a lower draw depth of the drawing punch 2 in the final contour 8 of the die 3, so that the cutting engagement between the cutting edge 4 and board 1 is already at a lower draw depth. The cut then continues from point 5a until it rotates in both
Richtungen den Schneidpunkt 5b erreicht. Am Punkt 5b der Schneidlinie geht die Einlaufkontur 5 der Matrize 3 zuletzt in die Endkontur 8 der Matrize über, so dass hier der Directions reaches the cutting point 5b. At point 5b of the cutting line, the inlet contour 5 of the die 3 transitions lastly into the final contour 8 of the die, so that here the
Schneideingriff zwischen Schneidkante und Platine zuletzt erfolgt. Die Schneidkante kann aufgrund der Ausbildung der Einlaufkontur 5 der Matrize 3 geradlinig ausgebildet sein und dennoch wird ein fortlaufender Schneidvorgang ermöglicht, der nur geringe Schneidkräfte erfordert. In Fig. 3 ist nun ein weiteres Ausführungsbeispiel der Cutting action between cutting edge and board last done. The cutting edge can be formed in a straight line due to the formation of the inlet contour 5 of the die 3 and yet a continuous cutting process is possible, which requires only low cutting forces. In Fig. 3 is now another embodiment of
Matrize 3 in einer perspektivischen Ansicht dargestellt. Die Einlaufkontur 5 ist entlang der Schneidlinie 7 mit einem zahnartigen Höhenprofil ausgebildet, so dass die Schneidlinie am Schneidpunkt 7a den Beginn des Schneideingriffs zwischen Schneidkante und Platine markiert. Das Beschneiden der Die 3 shown in a perspective view. The inlet contour 5 is formed along the cutting line 7 with a tooth-like height profile, so that the cutting line at the cutting point 7a marks the beginning of the cutting engagement between the cutting edge and the circuit board. The trimming of the
Platine beginnt daher am Punkt 7a und setzt sich bei weiterer Verlagerung der Position des Ziehstempels in die Matrize zum tiefsten Punkt der Schneidlinie 7b. Wie an dem Beispiel aus Fig. 3 zu erkennen ist, erfolgt der Schneideingriff in dieBoard therefore starts at point 7a and continues on further displacement of the position of the drawing punch in the die to the lowest point of the cutting line 7b. As can be seen from the example of FIG. 3, the cutting engagement takes place in the
Platine gleichzeitig an mehreren Punkten der Schneidlinie 7. Der Beschnitt setzt sich dann von diesen Punkten der Board simultaneously at several points of the cutting line 7. The trimming then sits down from these points of
Schneidlinie 7a zu den tiefer gelegenen Punkten der Cutting line 7a to the lower points of the
Schneidlinie 7b, 7c fort, wenn der Ziehstempel tiefer in die Matrize 3 bewegt wird. Die Platine wird also bereichsweise und gleichzeitig an mehreren Punkten im Schneideingriff mit der Schneidkante des Ziehstempels stehen und fortlaufend bei Verlagerung des Ziehstempels in die Matrize hinein Cutting line 7b, 7c continues when the drawing punch is moved deeper into the die 3. The board will thus be partially and simultaneously at several points in cutting engagement with the cutting edge of the drawing die and continuously in moving the drawing punch into the die into it
