Description

Die Erfindung bezieht sich auf eine Prägeeinheit zur Anbringung von Kennzeichnungen an Bauteilen, mit einem Gehäuse und gegebenenfalls einer das Gehäuse tragenden Konsole.The invention relates to a stamping unit for attaching markings to components, with a housing and possibly a console carrying the housing.

Die Prägetechnik dient in der Industrie unter anderem dazu, Bauteile mit Zahlen, Buchstaben, Symbolen, Stempeln und dergleichen zu kennzeichnen. Dies ist häufig erforderlich, um den Ursprung der Herstellung, der Charge usw. zurückverfolgen zu können. Insbesondere in der Kraftfahrzeugtechnik ist es von Bedeutung, den Hersteller des entsprechenden Bauteils zu ermitteln, beispielsweise bei Rückrufaktionen oder Schadensfeststellungen an Kraftfahrzeugen.The embossing technique is used in industry, among other things, to identify components with numbers, letters, symbols, stamps and the like. This is often necessary to trace the origin of the production, the batch, etc. In particular, in automotive technology, it is important to determine the manufacturer of the corresponding component, for example, in recall actions or damage findings on motor vehicles.

Weiterhin ist es insbesondere in der Metallbauteilfertigung üblich, in der laufenden Produktion Tagesstempel und/oder Bauteilstempel in oder auf das zu fertigende Blechteil oder andere Bauteile ein- oder aufzubringen. Über ein Stempelwerkzeug werden Signaturen, Kennzeichnungen, Buchstaben, Zahlen usw. in oder auf das Bauteil geprägt. Dabei werden Prägemaschinen verwendet, die beispielsweise bei etwa 3 mm großen Kennzeichnungen eine Prägekraft von ca. 3 bis 4 t aufbringen, um die Kennzeichnung einzuprägen. Dazu werden üblicherweise Prägezangen verwendet, die sehr groß bauen, d.h. etwa 0,5 m hoch und höher sind, und einen entsprechend starken Kraftantrieb benötigen. Manche Prägezange besitzt ein Rollwerk, mit dem die zu prägenden Kennzeichnungen schrittweise fortlaufend weitergestellt werden können. Dieser Prägevorgang wird auch als Rollprägen bezeichnet.Furthermore, it is customary, in particular in metal component manufacturing, to apply or apply daily stamps and / or component stamps in or on the sheet metal part or other components to be produced during ongoing production. Sign tools, markings, letters, numbers, etc. are stamped in or on the component using a stamp tool. This embossing machines are used, for example, apply an embossing force of about 3 to 4 t at about 3 mm large markings to impress the label. For this purpose usually embossing pliers are used, which build very large, ie about 0.5 m high and higher, and require a correspondingly strong power drive. Some embossing pliers have a scrollwork, with which the markings to be stamped can be progressively incrementally continued. This embossing process is also referred to as roll embossing.

Diese Prägezangen haben den Nachteil, dass ein großer Platzbedarf am zu fertigenden und zu kennzeichnenden Bauteil notwendig ist, da eine Prägezange viel Platz benötigt, um das Bauteil angreifen zu können. Bei kleiner dimensionierten Bauteilen oder komplizierten Bauformen ergeben sich dadurch Platzprobleme.These embossing pliers have the disadvantage that a large amount of space on the component to be manufactured and marked is necessary because an embossing pliers requires a lot of space to attack the component can. For smaller sized components or complicated designs, this results in space problems.

Das Rollprägen kann auch in der Form ausgeführt werden, dass das Prägerad der Prägeeinheit an seinem Umfang verteilte Kennzeichnungen aufweist. Das Prägerad fährt mit sehr hohem Kraftaufwand über die Prägestelle des Bauteils. Dabei muss die Prägeeinheit dennoch zum Bauteil und vom Bauteil weggefahren werden, so dass auch hier ein großer Platzbedarf notwendig ist.The roll embossing can also be carried out in the form that the embossing wheel of the embossing unit has distributed at its periphery markings. The embossing wheel moves with very high force over the embossing point of the component. Nevertheless, the embossing unit must still be moved away to the component and the component, so that here too, a large space requirement is necessary.

Es ist Aufgabe der Erfindung, eine Prägeeinheit zur Anbringung von Kennzeichnungen an Bauteilen der eingangs genannten Art zu schaffen, die insbesondere kompakt ausgebildet ist und eine relativ geringe Antriebskraft benötigt.It is an object of the invention to provide a stamping unit for attaching markings to components of the type mentioned, which is particularly compact and requires a relatively low driving force.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass im Gehäuse eine axial verschiebbare und um ihre Längsachse verschwenkbare Antriebswelle angeordnet ist, die an ihrem einen Ende unter Vorspannung mit einer Antriebseinheit verbunden ist und an ihrem anderen Ende ein Andruckteil aufweist, am Gehäuse ein Kennzeichnungsmittel aufweisendes Bauelement angeordnet ist, auf dem das zu kennzeichnendes Bauteil aufsetzbar ist, wobei während des Prägevorganges das Andruckteil der Antriebswelle mit einem bestimmten Anpressdruck gegen das zu kennzeichnende Bauteil und das Kennzeichnungsmittel aufweisende Bauelement andrückbar und an diesem fortlaufend entlang verschwenkbar ist und das Kennzeichnungsmittel aufweisende Bauelement die Kennzeichnung in das Bauteil einprägt.According to the invention the object is achieved in that in the housing an axially displaceable and pivotable about its longitudinal axis drive shaft is arranged, which is connected at its one end under bias to a drive unit and at its other end has a pressing member, arranged on the housing a marking component exhibiting component is on which the component to be marked can be placed, wherein during the embossing process, the pressure part of the drive shaft with a certain contact pressure against the component to be marked and the marking means having component and pressed on this continuously along and is pivoting and having the identification means Component imprinting the marking in the component.

Unter dem Begriff "Gehäuse" sollen geschlossene als auch offene Konstruktionen verstanden werden, welche die Aufgabe haben, die Antriebswelle zu halten bzw. zu führen.The term "housing" is to be understood as meaning both closed and open constructions which have the task of holding or guiding the drive shaft.

Die axiale Verschiebbarkeit der Antriebswelle ermöglicht eine Bewegung des an einem Ende der Antriebswelle befestigten Andruckteils hin zu und weg von einem zu kennzeichnenden Bauteil. Weiterhin erlaubt die Verschwenkbarkeit der Antriebswelle um ihre Längsachse ein fortlaufendes, d.h. kontinuierliches Abwälzen des Andruckteils auf dem die Kennzeichnungsmittel aufweisenden Bauelement, auf dem ein zu kennzeichnendes Bauteil aufgesetzt ist. Unter "Kennzeichnungen" sind Signaturen, wie Zahlen, Buchstaben, Symbole, Stempel und dergleichen zu verstehen, die auf oder in ein zu fertigendes oder bereits gefertigtes Bauteil auf- oder eingebracht werden.The axial displaceability of the drive shaft allows movement of the attached to one end of the drive shaft pressure member toward and away from a component to be identified. Furthermore, the pivotability of the drive shaft about its longitudinal axis allows a continuous, i. continuous rolling of the pressure on the component having the marking means on which a component to be marked is placed. "Markings" are signatures, such as numbers, letters, symbols, stamps and the like to understand that are on or in a to be manufactured or already manufactured component or introduced.

Die Antriebswelle ist an ihrem einen Ende unter Vorspannung mit einer Antriebseinheit verbunden, so dass der Anpressdruck der Andruckwelle an das Kennzeichnungsmittel aufweisende Bauelement festgelegt wird.The drive shaft is connected at its one end under bias to a drive unit, so that the contact pressure of the pressure wave is fixed to the identification means having component.

Da die Antriebswelle relativ kurz ausgebildet sein kann, hat das Gehäuse eine kompakte Abmessung. Darüber hinaus baut durch die Anordnung der Antriebseinheit an einem Ende der Antriebswelle und die Anordnung des Andruckteils am anderen Ende der Antriebswelle die Prägeeinheit so klein, dass diese in eine Spannvorrichtung, vorzugsweise eine Positioniervorrichtung gemäß der DE 20 2006 016 392 und/oder einer Konsole gemäß der DE 20 2006 000 908 integriert werden kann, ohne dass Platzprobleme auftreten. Zum Prägevorgang selbst sind keine weiteren Bauteile, wie Halterungen, Zuführungen usw. notwendig.Since the drive shaft can be made relatively short, the housing has a compact size. In addition, builds by the arrangement of the drive unit at one end of the drive shaft and the arrangement of the pressure member at the other end of the drive shaft, the embossing unit so small that these in a clamping device, preferably a positioning device according to DE 20 2006 016 392 and / or a console according to the DE 20 2006 000 908 can be integrated without space problems occur. For embossing itself are no other components, such as brackets, feeders, etc. necessary.

Für einen Prägevorgang wird das mit einer Prägung zu versehende Bauteil über dem Kennzeichnungsmittel aufweisenden Bauelement platziert, d.h. es kann einfach auf dem Bauelement am Gehäuse der Prägeeinheit aufgelegt werden. Während des Prägevorganges wird das Andruckteil der Antriebswelle mit einem bestimmten Anpressdruck gegen das zu kennzeichnende Bauteil und das Kennzeichnungsmittel aufweisende Bauelement gedrückt und an diesem fortlaufend entlang verschwenkt. Dabei prägt das Kennzeichnungsmittel die Kennzeichnung von unten in das Bauteil ein. Danach kann das mit der Prägung versehene Bauteil auch wieder einfach entnommen werden. Unter "Prägung" soll im Sinne der Erfindung auch ein Stempeln verstanden werden.For an embossing operation, the component to be embossed is placed over the identifier-containing device, i. it can simply be placed on the component on the housing of the embossing unit. During the embossing process, the pressing part of the drive shaft is pressed with a certain contact pressure against the component to be marked and the identification means having component and pivoted on this continuously along. The identification means imprints the marking from below into the component. Thereafter, the provided with the embossed component can also be easily removed again. Under "embossing" in the context of the invention, a stamping should be understood.

Die Erfindung ergibt eine kleine kompakte Prägeeinheit mit geringer Bauhöhe, die mit geringer Antriebskraft und genauen Einstellmöglichkeiten einen Prägevorgang für zu kennzeichnende Bauteile ermöglicht. Die Prägeeinheit kann beliebig in eine Fertigungsvorrichtung, z.B. eine Schweißvorrichtung, integriert werden, ohne das ein Bewegen der Prägeeinheit, d.h. Zuführen und Wegfahren zur Prägestelle, erforderlich ist. Die Prägeeinheit ist also immer ortsfest mit der Fertigungsvorrichtung verbunden. Darüber hinaus ist die Prägeeinheit wegen ihrer Kompaktheit auch bei engen Platzverhältnissen und komplizierten Bauformen einsetzbar.The invention results in a small compact embossing unit with a low height, which allows a low-power and accurate adjustment an embossing process for components to be marked. The embossing unit can be arbitrarily placed in a manufacturing apparatus, e.g. a welding device, without moving the embossing unit, i. Feeding and driving away to the embossment, is required. The embossing unit is thus always connected in a stationary manner to the production apparatus. In addition, the embossing unit can be used because of its compactness even in tight spaces and complicated designs.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen entnehmbar.Advantageous embodiments and further developments of the invention can be taken from the subclaims.

Demgemäß ist das Kennzeichnungsmittel aufweisende Bauelement als Stempelhalter ausgebildet. Darüber umfasst das Kennzeichnungsmittel ein- oder mehrteilige Stempel, die Zahlen, Buchstaben, Symbole und/oder dergleichen aufweisen, welche vorzugsweise erhaben ausgebildet sind und somit ein Prägen gestatten. Der Stempelhalter kann in Abhängigkeit von der gewünschten Kennzeichnung feste, austauschbare oder sich selbst fortlaufend ein- bzw. verstellbare Stempel aufweisen.Accordingly, the identifier is having device designed as a punch holder. In addition, the identification means comprises single-part or multi-part stamps, which have numbers, letters, symbols and / or the like, which are preferably formed raised and thus allow embossing. The punch holder may have fixed, interchangeable or self-continuously adjustable or adjustable punches depending on the desired label.

Da das zu prägende Bauteil auf den Stempelhalter mit den Stempeln aufgelegt wird und das Andruckteil dann unter Druck auf dem Bauteil über den Stempelbereich verschwenkt, wird die gewünschte Kennzeichnung von unten in das Bauteil eingeprägt. Dabei ist vorgesehen, dass das Andruckteil quer zur Längsachse der Antriebswelle angeordnet und als Welle, Rolle oder Walze ausgebildet ist. Weil das Andruckteil unmittelbar an einem Ende der Antriebswelle und der Stempelhalter in unmittelbarer Nähe der Antriebswelle am Gehäuse angeordnet sind, ist das Andruckteil sehr kurz, so dass der Anpressdruck vollständig auf das zu prägende Bauteil übertragen wird. Durch die Festlegung der Form, Breite und Länge des Andruckteils kann in Abhängigkeit von der Kennzeichnungsform und -größe der Prägebereich eingestellt werden.Since the component to be embossed is placed on the punch holder with the punches and the pressure member then pivoted under pressure on the component on the stamp area, the desired marking is impressed from below into the component. It is provided that the pressure member is arranged transversely to the longitudinal axis of the drive shaft and formed as a shaft, roller or roller. Because the pressure member is disposed directly at one end of the drive shaft and the punch holder in the immediate vicinity of the drive shaft on the housing, the pressure member is very short, so that the contact pressure is completely transferred to the component to be embossed. By defining the shape, width and length of the pressure member can be adjusted depending on the identification form and size of the embossing area.

Bevorzugt ist die Antriebswelle mittels eines an sich bekannten Tellerfederpakets vorgespannt. Hierbei erfolgt die Vorspannung der Antriebswelle beispielsweise über eine dem Tellerfederpaket zugeordneten Stellmutter.Preferably, the drive shaft is biased by means of a disc spring package known per se. In this case, the bias of the drive shaft, for example via a plate spring assembly associated adjusting nut.

Bei der erfindungsgemäßen Prägeeinheit besteht die Antriebseinheit für die Antriebswelle aus einem Antriebsmotor und einem Getriebe. Der Antriebsmotor kann ein Pneumatikmotor, Elektromotor oder dergleichen und das Getriebe ein Schnecken-, Zahnrad-, Zahnstangengetriebe oder dergleichen sein. Wenn sich das Andruckteil vor dem Prägevorgang in Nullposition befindet, verfährt beispielsweise das mit dem Pneumatikmotor angetriebene Schneckengetriebe die Antriebswelle in axialer Richtung, d.h. also quer zur Stempelebene, und verschwenkt dann das Andruckteil über den Prägebereich und vollzieht die Kennzeichnung des Bauteils. Dieser Prägevorgang geschieht in sehr kurzer Zeit, z.B. innerhalb 1 oder 2 Sekunden oder sogar Sekundenbruchteilen.In the embossing unit according to the invention, the drive unit for the drive shaft consists of a drive motor and a transmission. The drive motor may be a pneumatic motor, electric motor or the like, and the transmission may be a worm, gear, rack gear or the like. If If the pressure part is in the zero position before the embossing process, for example, the worm gear driven by the pneumatic motor moves the drive shaft in the axial direction, ie transversely to the punch plane, and then pivots the pressure part over the embossing area and completes the marking of the component. This embossing process takes place in a very short time, eg within 1 or 2 seconds or even fractions of a second.

Mit einem relativ kleinen Pneumatik-Lamellenmotor oder Elektromotor mit zugehörigem Schneckengetriebe mit entsprechender Übersetzung und dem darauf abgestimmten Tellerfederpaket kann die erforderliche Andruckkraft mit wenigen Newtonmeter Antriebsdrehmoment relativ klein gehalten werden. Diese relativ geringe Antriebsenergie bzw. Andruckkraft ist auch deshalb ausreichend, weil durch das fortlaufende, d.h. kontinuierliche Abwälzen des Andruckteils jeder Teil der Gesamtkennzeichnung, z.B. Ziffer für Ziffer, Buchstabe für Buchstabe usw., nacheinander geprägt wird.With a relatively small pneumatic vane motor or electric motor with associated worm gear with the appropriate translation and the matched plate spring package, the required pressure force can be kept relatively small with few Newtonmeter drive torque. This relatively low drive energy or pressure force is also sufficient because the continuous, i. continuous rolling of the pressing member, each part of the overall marking, e.g. Number by digit, letter by letter, etc., one after the other.

Nach einer weiteren Ausgestaltung der erfindungsgemäßen Prägeeinheit sind Steuermittel zum Ein- und Ausschalten der Antriebseinheit und zum Verschwenken der Antriebswelle hin zum und weg vom Kennzeichnungsmittel aufweisenden Bauelement vorgesehen. Hierbei bestehen die Steuermittel vorzugsweise zumindest aus einem auf der Antriebswelle ausgebildeten Schaltnocken und einem zugeordneten Näherungsschalter, welcher die Position der Antriebswelle detektiert.According to a further embodiment of the embossing unit according to the invention control means are provided for switching on and off of the drive unit and for pivoting the drive shaft towards and away from the identification means having component. In this case, the control means preferably comprise at least one switching cam formed on the drive shaft and an associated proximity switch which detects the position of the drive shaft.

Des Weiteren ist vorgesehen, dass das Gehäuse auf einer Konsole, einem Fußteil, einem Gelenk oder dergleichen befestigt ist, beispielsweise auf einer Positioniervorrichtung gemäß der DE 20 2006 016 392 und/oder einer Konsole gemäß der DE 20 2006 000 908 .Furthermore, it is provided that the housing is mounted on a console, a foot part, a hinge or the like, for example on a positioning device according to the DE 20 2006 016 392 and / or a console according to the EN 20 2006 000 908 ,

Es versteht sich, dass die vorstehend genannten und nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the features mentioned above and those yet to be explained can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.

Die Prägeeinheit 1 gemäß den Fig. 1 bis 5 weist ein Gehäuse 2 auf, welches beispielhaft mit einem schwenkbaren Halter 3 mittels nicht gezeigter Stifte verbunden ist. Der Halter 3 wiederum ist mit einem Fuß 4, gegebenenfalls einer Konsole, einem Gelenk oder einer Positioniervorrichtung, verbunden, der, falls erforderlich, über eine Shimsplatte 5, die zur Höhenpositionierung der Prägeeinheit dient, an einer Fußplatte 6 befestigt ist. Die Prägeeinheit 1 kann damit auf einer nicht gezeigten Basis, beispielsweise einer Montageplatte oder Schweißvorrichtung, platziert werden.The embossing unit 1 according to the Fig. 1 to 5 has a housing 2, which is connected by way of example with a pivotable holder 3 by means not shown pins. The holder 3 in turn is connected to a foot 4, optionally a bracket, a hinge or a positioning device, which, if necessary, via a Shimsplatte 5, for height positioning the embossing unit is attached to a base plate 6. The embossing unit 1 can thus be placed on a base, not shown, for example, a mounting plate or welding device.

Die in Fig. 5 gezeigte Ansicht der Prägeeinheit 1 enthält Strichlinien, welche die Einbaurichtung der jeweiligen Teile der Prägeeinheit 1 verdeutlichen sollen. Des Weiteren ist in den Fig. 1 bis 4 jeweils ein mit einer Kennzeichnung zu versehenes, d.h. zu prägendes Bauteil Z in Strich-Punkt-StrichLinien schematisch dargestellt.In the Fig. 5 shown view of the embossing unit 1 contains dashed lines, which are intended to illustrate the installation direction of the respective parts of the embossing unit 1. Furthermore, in the Fig. 1 to 4 in each case a component Z to be provided with a marking, that is to be embossed, is shown diagrammatically in dashed-dot-dashed lines.

Im Gehäuse 2 ist eine axial bewegliche und um ihre Längsachse verschwenkbare Antriebswelle 7 eingesetzt, auf der zumindest zwei beabstandete Kugellager 8 und zwei beabstandete Distanzringe 9 angeordnet sind, die in eine Gehäusebohrung 10 eingebracht sind. Der untere aus dem Gehäuse 2 herausragende Abschnitt 11 der Antriebswelle 7 ist im Querschnitt als Sechskant ausgebildet. Dieser sechskantige Abschnitt 11 führt unter Zwischenschaltung eines Tellerfederpaketes 12 mit einer zugehörigen Stellmutter 13 in ein Getriebe 14, z.B. ein Schneckengetriebe. Am unteren Ende der Antriebswelle 7 ist ein Schaltnocken 15 befestigt, der zusammen mit einem Näherungsschalter 16, der an einem Sensorhalter 17 befestigt ist, als Steuermittel dient.In the housing 2, an axially movable and pivotable about its longitudinal axis drive shaft 7 is used, on which at least two spaced ball bearings 8 and two spaced spacer rings 9 are arranged, which are introduced into a housing bore 10. The lower protruding from the housing 2 section 11 of the drive shaft 7 is formed in cross section as a hexagon. This hexagonal section 11 leads with the interposition of a disc spring assembly 12 with an associated adjusting nut 13 in a transmission 14, e.g. a worm gear. At the lower end of the drive shaft 7, a switching cam 15 is fixed, which serves as a control means together with a proximity switch 16 which is fixed to a sensor holder 17.

Der Sensorhalter 17 ist an einem Halteteil 18 befestigt. Dieses Halteteil 18 nimmt in einer Öffnung 19 einen Antriebsmotor 20, z.B. einen Pneumatik-Lamellen-Motor, auf, der mit dem Getriebe 14 mechanisch verbunden ist. Die Kopplung der Antriebswelle 7 mit der Motor-Getriebe-Einheit 14, 20 erfolgt dadurch, dass das Halteteil 18 mit dem Gehäuse 2 beispielsweise verschraubt wird.The sensor holder 17 is attached to a holding part 18. This holding part 18 receives in an opening 19 a drive motor 20, for example a pneumatic disk motor, which is mechanically connected to the gear 14. The coupling of the drive shaft 7 with the motor-gear unit 14, 20 is effected in that the holding part 18 is screwed to the housing 2, for example.

Die Antriebswelle 7 weist an ihrem oberen Ende ein als Walze, Welle oder Rolle ausgebildetes kurzes Andruckteil 21 auf, das über ein Kugellager 22 rechtwinklig von der Längsachse der Antriebswelle 7 wegragt. Auf der Oberseite des Gehäuses 2 ist eine Druckplatte 23 befestigt, auf der ein als Stempelhalter ausgebildetes Kennzeichnungsmittel aufweisendes Bauelement 24 positioniert ist. Das Kennzeichnungsmittel 17 umfasst nicht näher dargestellte ein- oder mehrteilige Stempel, die Zahlen, Buchstaben, Symbole und/oder dergleichen aufweisen, die erhaben ausgebildet sind.The drive shaft 7 has at its upper end designed as a roller, shaft or roller short pressure member 21 which projects at right angles from a ball bearing 22 from the longitudinal axis of the drive shaft 7. On the upper side of the housing 2, a pressure plate 23 is fixed, on which a component 24 having a marking means embodied as a punch holder is positioned. The identification means 17 comprises single-part or multi-part stamps not shown in more detail, which have numbers, letters, symbols and / or the like which are raised.

Der Schaltnocken 15 ist mit dem als Inititator dienenden Näherungsschalter 16 in Eingriff bringbar, der wiederum das Einschalten eines Antriebes zur Auslösung des Prägevorganges initiiert und das Ausschalten des Antriebes bewirkt, wenn der Prägevorgang abgeschlossen ist.The switching cam 15 can be brought into engagement with the proximity switch 16 serving as an initiator, which in turn initiates the switching on of a drive for triggering the embossing process and causes the drive to be switched off when the embossing process has been completed.

In Nullposition der Antriebswelle 7 wird die Andruckkraft der Antriebswelle 7 für das Andruckteil 21 durch das Tellerfederpaket 12 erzeugt. Bei Anlage des Andruckteils 21 am zu kennzeichnenden Bauteil Z, welches zwischen dem Andruckteil 21 und dem Kennzeichnungsmittel aufweisenden Bauelement 24 platziert ist, wird durch die Antriebseinheit 15 ,20 ein Druck aufgebaut und die Antriebswelle 7 wird linear, d.h. axial gegen das auf dem Kennzeichnungsmittel aufweisenden Bauelement 24 platzierte Bauteil Z verschoben und schwenkt mit dem Andruckteil 21 über die Prägestelle am Bauteil Z, so dass die Stempel des Kennzeichnungsmittels aufweisenden Bauelementes 24 durch ihre erhabene Ausbildung eine Signatur in das Bauteil Z prägen. Dann verfährt die Antriebswelle 7 mit dem Andruckteil 21 wieder in die Nullposition und das mit der Kennzeichnung versehene Bauteil Z kann entfernt werden. Da die Prägeeinheit 1 vorteilhafterweise nach oben offen ist, kann das Bauteil Z nach dem Prägen einfach entnommen werden ohne dass eine zusätzliche Verfahreinheit notwendig ist.In zero position of the drive shaft 7, the pressing force of the drive shaft 7 for the pressure member 21 is generated by the plate spring assembly 12. When the press-on part 21 bears against the component Z to be marked, which is placed between the press-on part 21 and the component 24, a pressure is built up by the drive unit 15, 20 and the drive shaft 7 becomes linear, ie axially against that on the marking means Component 24 placed component Z moves and pivots with the pressure member 21 on the embossing point on the component Z, so that the stamp of the marking means having component 24 form a signature in the component Z by their sublime training. Then the drive shaft 7 moves with the pressure member 21 back to the zero position and provided with the marking component Z can be removed. Because the Embossing unit 1 is advantageously open at the top, the component Z can be easily removed after embossing without an additional positioning unit is necessary.
