Description
Die Erfindung betrifft einen Schlitten einer Presse mit einem Werkzeughalter mit einer Werkzeugjustierung sowie eine Anordnung aus einem derartigen Schlitten und einem entsprechenden Werkzeug. Insbesondere betrifft die Erfindung das Gebiet der Schlitten bei Stufenpressen oder ähnlichen Maschinen, bei welchen ein Stempel mit wenigstens einem Werkzeug hin und her in einer Arbeitsrichtung bewegt wird.The invention relates to a carriage of a press with a tool holder with a tool adjustment and an arrangement of such a carriage and a appropriate tool. In particular, the invention relates to the field the slide in step presses or similar machines, in which a stamp with at least one tool back and forth in one direction is moved.
Eine derartige Mehrstufenpresse ist beispielsweise aus der EP 0 354 428
A2 bekannt, welche auch die Basis für den Oberbegriff der Ansprüche
1 und 2 bildet. Diese umfasst einen Werkzeughalter, bei welchem mehrere
Stempel in Werkzeughalterungen an einen hin und her beweglichen Schlitten
gehalten werden. Durch die Hin- und Herbewegung werden die Stempel
gegen dazu gehörige Matrizen gepresst und hierdurch ein zwischen
Stempel und Matrize angeordnetes Werkstück bearbeitet. Mit jedem Hub
des Schlittens werden die einzelnen Werkstücke mittels Greifer entlang
einer Transportrichtung von einem Stempel-Matrizen-Paar zum nächsten
transportiert.Such a multi-stage press is known for example from EP 0 354 428
A2, which also forms the basis for the preamble of the
Damit die Art der hergestellten bzw. bearbeiteten Werkstücke verhältnismäßig schnell geändert werden kann, ist an dem Schlitten ein Wechselhalter vorgesehen, an welchem die einzelnen Werkzeughalterungen angebracht sind. Dieser Wechselhalter umfasst eine Wechselplatte, in welcher je Werkzeughalterung ein Keil angeordnet ist, welcher über eine eine Werkzeuganlage aufweisende Zwischenbuchse eine Justierung der einzelnen Stempel ermöglicht. Durch Justierung der justierbaren Keile kann die Werkzeuganlage in eine Justierrichtung verlagert und somit eine genaue Justierung der einzelnen Stempel gewährleistet werden. Die einzelnen justierbaren Keile sind in der Wechselplatte seitlich geführt. Dieses geschieht insbesondere durch eine Führung der Keile untereinander sowie eine seitliche Begrenzung des die Keile aufnehmenden Raumes in der Wechselplatte. Darüber hinaus stützt sich der Keil an einem Keilhinterlager ab und kann auf diese Weise den auf ihn durch den Stempel über das Zwischenstück ausgeübten Kräften begegnen.Thus the type of manufactured or machined workpieces relatively can be changed quickly, is on the carriage a change holder provided on which the individual tool holders attached are. This change holder comprises a removable plate, in which per tool holder a wedge is arranged, which has a one Tooling having intermediate bush an adjustment of the individual Stamp allows. By adjusting the adjustable wedges, the Moves tool in a Justierrichtung and thus an accurate Adjustment of each stamp can be guaranteed. The single adjustable Wedges are guided laterally in the removable plate. This happens in particular by a guidance of the wedges with each other and a lateral Limiting the wedges receiving space in the removable disk. In addition, the wedge is supported by a wedge-shaped rear bearing and This way you can put it on the punch through the intermediate piece encountered forces.
Diese Anordnung hat jedoch den Nachteil, dass hierdurch eine Führungslänge, die am Schlitten zur Verfügung steht, um diesen ausreichend präzise hin und her zu bewegen, verkürzt wird.However, this arrangement has the disadvantage that this results in a guide length, which is available on the slide to this sufficiently precise to move back and forth, is shortened.
Es ist Aufgabe vorliegender Erfindung, einen Werkzeughalter bzw. eine Anordnung aus Werkzeughalter und Werkzeug bereit zu stellen, bei welchen eine möglichst große Führungslänge für den Schlitten bei gleichen baulichen Abmessungen einer entsprechenden Maschine gewährleistet ist.It is an object of the present invention, a tool holder or a Arrangement of tool holder and tool to provide, in which the largest possible guide length for the slide at the same structural dimensions of a corresponding machine is guaranteed.
Als Lösung schlägt die Erfindung einerseits einen Schlitten einer Presse mit einen Werkzeughalter mit einer Werkzeugjustierung vor, bei welchem wenigstens zwei Werkzeuge in jeweils einer Werkzeughalterung an dem Schlitten gehalten werden können, wobei die Werkzeugjustierung je Werkzeug einen justierbaren Keil, ein Keilhinterlager, eine Keilführung sowie eine Werkzeuganlage umfasst und derart ausgebildet ist, dass ein Justieren des Keils eine Verlagerung der Werkzeuganlage in eine Justiereinrichtung bewirkt, welcher sich dadurch auszeichnet, dass jede der wenigstens zwei Werkzeughalterungen gemeinsam mit dem zugehörigen Keil jeweils separat als eine bauliche Einheit von dem Schlitten abnehmbar ist.As a solution, the invention proposes on the one hand a carriage of a press with a tool holder with a Tool adjustment before, in which at least two tools in each of a tool holder can be held on the carriage, wherein the tool adjustment per tool an adjustable wedge, a wedge rear bearing, a wedge guide and a tool system includes and so is formed, that an adjustment of the wedge a displacement of the tool system effected in an adjusting device, which is characterized by that each of the at least two tool holders together with the associated wedge each separately as a structural unit of the carriage is removable.
Dadurch dass die Werkzeughalterung und der Keil als eine bauliche Einheit abnehmbar sind, können diese als eine Baugruppe wesentlich kompakter ausgebildet werden. Der Verzicht auf ansonsten notwendige Verbindungselemente, Halteplatten und ähnliches sowie die hieraus resultierende Kompaktheit ermöglichen es, dass der gesamte Werkzeughalter wesentlich kleiner baut und somit mehr Platz für den Stempel und entsprechende Schlittenführung verbleibt.By making the tool holder and the wedge as a structural unit are removable, they can be much more compact than an assembly be formed. The renunciation of otherwise necessary fasteners, Holding plates and the like and the resulting Compactness allow the entire tool holder to be essential smaller builds and thus more space for the stamp and corresponding Slide guide remains.
Die Anordnung hat darüber hinaus den Vorteil, dass, falls ein Keil während des Betriebes beschädigt wird, lediglich der entsprechende Werkzeughalter mit dem Keil ausgewechselt werden braucht. Bei den bekannten Anordnungen muss jeweils der gesamte Werkzeughalter mit den noch intakten Keilen und Werkzeughalterungen ausgewechselt werden.The arrangement also has the advantage that if a wedge during the operation is damaged, only the corresponding tool holder needs to be replaced with the wedge. In the known Arrangements must each be the entire tool holder with the still intact Wedges and tool holders are replaced.
Darüber hinaus kann bei einer derartigen Anordnung auf ein Zwischenstück verzichtet werden, wodurch sich die Zahl der Teile reduziert. Hierdurch lassen sich einerseits die Kosten und andererseits die Störanfälligkeit vermindern. In addition, in such an arrangement on an intermediate piece be omitted, which reduces the number of parts. hereby on the one hand the costs and on the other the susceptibility to failure Reduce.
Als weitere Lösung schlägt die Erfindung einen Schlitten einer Presse mit einem Werkzeughalter mit einer Werkzeugjustierung vor, bei welchem ein Werkzeug in einer Werkzeughalterung an dem Schlitten gehalten werden kann, wobei die Werkzeugjustierung einen justierbaren Keil, ein Keilhinterlager, eine Keilführung sowie eine Werkzeuganlage umfasst und derart ausgebildet ist, dass ein Justieren des Keils eine Verlagerung der Werkzeuganlage in eine Justierrichtung bewirkt, welcher sich dadurch auszeichnet, dass die Werkzeughalterung und die Keilführung einstückig miteinander ausgebildet sind.As a further solution, the invention proposes a carriage of a press with a tool holder with a Tool adjustment in which a tool in a tool holder can be held on the carriage, the tool adjustment an adjustable wedge, a wedge rear bearing, a wedge guide and a Includes tool and is designed such that an adjustment of the Wedge causes a displacement of the tool installation in an adjustment direction, which is characterized in that the tool holder and the wedge guide are integrally formed with each other.
Auch die einstückige Ausbildung von Werkzeughalterung und Keilführung bedingt eine besonders kompakte Bauweise, durch welche eine entsprechende Größenreduktion des Werkzeughalters mit den bereits oben geschilderten Vorteilen ermöglicht wird.Also, the one-piece design of tool holder and wedge guide requires a particularly compact design, through which a corresponding Size reduction of the tool holder with the already described above Benefits is made possible.
In vorliegendem Zusammenhang bezeichnet der Begriff "Werkzeuganlage" jede Anlage bzw. jeden Anschlag, an welchen ein Werkzeug, welches durch die Werkzeughalterung gehalten werden soll zwecks Justierung zur Anlage kommt. Ist beispielsweise die Werkzeughalterung als Ausnehmung, wie beispielsweise als Hohlzylinder oder Hohlquader, ausgestaltet, in welche ein Werkzeug eingeschoben und darin befestigt werden kann, so wird das entsprechende Werkzeug in die Ausnehmung geschoben, bis es an der Werkzeuganlage zur Anlage kommt. Insofern kann durch Verlagerung der Werkzeuganlage die Tiefe, mit welcher ein Werkzeug in die Werkzeughalterung eingeführt werden kann, eingestellt werden, so dass die Öffnungsrichtung der Ausnehmung die entsprechende Justierrichtung definiert. Hierbei versteht es sich, dass die Justierrichtung auch auf andere Weise gewählt und die Verlagerung auf andere Weise wirksam werden kann.In the present context, the term "tool installation" each plant or each stop to which a tool, which is to be held by the tool holder for the purpose of adjustment for Plant comes. For example, if the tool holder as a recess, such as hollow cylinder or hollow cuboid, designed, in which a tool can be inserted and fixed in it, so the corresponding tool is pushed into the recess until it comes to the tool plant to the plant. In that respect, by relocation the tooling the depth with which a tool in the Tool holder can be inserted, adjusted so that the opening direction of the recess the corresponding adjustment direction Are defined. It goes without saying that the adjustment direction also applies to others Chosen way and the shift in another way take effect can.
Während in vorliegendem Zusammenhang die Keilführung dafür sorgt, dass der Keil entlang einer Verstellrichtung geführt justierbar ist, dient das Keilhinterlager dazu, den größten Teil der auf den Keil durch das Werkzeug ausgeübten Kräfte zu kompensieren. Es versteht sich, dass ein Teil der Kräfte auch durch weitere Feststellmittel, wie beispielsweise die Verstelleinrichtung für den Keil, aufgenommen werden kann.While in the present context, the wedge guide ensures that the wedge is guided guided along an adjustment, this serves Wedge back bearing to do most of the on the wedge through the tool compensate for the forces exerted. It is understood that a part the forces also by further locking means, such as the adjustment for the wedge, can be included.
Der Werkzeughalter baut besonders kompakt, wenn auch das Keilhinterlager einstückig mit der Werkzeughalterung ausgebildet ist. Diese Anordnung hat darüber hinaus den Vorteil, dass hierdurch die Werkzeughalterung auch bei Belastung des Werkzeuges in sich die Kräfte des Keils aufnimmt, so dass die Belastung auf die Baugruppe, welche Schlitten-seitig an die Werkzeughalterung anschließt, vermindert wird. Insofern kann diese Baugruppe entsprechend leichter bzw. kleiner und somit platzsparender ausgebildet werden.The tool holder is particularly compact, even if the wedge-shaped rear bearing is formed integrally with the tool holder. This arrangement has the additional advantage that thereby the tool holder even when the tool is loaded, the forces of the wedge are absorbed by it, so that the load on the assembly, which slide side the tool holder connects, is reduced. Insofar, this can Assembly accordingly lighter or smaller and thus space-saving be formed.
Darüber hinaus ermöglicht die einstückige Verbindung von Keilhinterlager und Werkzeughalterung, dass bei einer Zerstörung des Keilhinterlagers, welches in der Regel mit einer Zerstörung des Keils einhergeht, durch einen verhältnismäßig schnell und einfach durchzuführenden Austausch der Werkzeughalterung die beschädigten Teile ersetzt werden können. Dieses gilt insbesondere im Zusammenhang mit Maschinen, welche mehrere Werkzeughalterungen aufweisen. Bei derartigen Maschinen braucht dann lediglich die Werkzeughalterung mit dem defekten Keilhinterlager ausgetauscht werden. Es versteht sich, dass die einstückige Ausbildung von Werkzeughalterung und Keilhinterlager auch unabhängig von der einstückigen Ausbildung von Werkzeughalterung und Keilführung vorteilhaft ist.In addition, the one-piece connection enables wedge-shaped rear bearings and tool holder, that upon destruction of the wedge support, which is usually accompanied by a destruction of the wedge, by a relatively quick and easy to carry out the exchange Tool holder the damaged parts can be replaced. This especially in connection with machines which have several Have tool holders. In such machines then needs just replaced the tool holder with the defective wedge rear bearing become. It is understood that the one-piece training of Tool holder and wedge support also independent of the one-piece Training tool holder and wedge guide advantageous is.
Um ein Auswechseln des Werkzeugs bzw. der Werkzeuge zu erleichtern, kann ein Wechselhalter vorgesehen sein, welcher lösbar mit dem Schlitten verbunden ist und an welchem die Werkzeughalterungen vorgesehen sind. Insbesondere können mehrere Werkzeughalterungen an einem derartigen Wechselhalter angebracht sein, so dass ein Werkzeugwechsel besonders einfach durchgeführt werden kann. In der Regel werden nämlich mehrere Werkzeuge als Gruppe gewechselt, da bei einem Wechsel des Werkstücks eine entsprechend andere Folge an Werkzeugen benötigt wird.To facilitate replacement of the tool or tools, may be provided a change holder which releasably connected to the carriage is connected and on which the tool holders are provided. In particular, a plurality of tool holders may be attached to such Removable holder be attached so that a tool change especially can be easily done. As a rule, several will be Tools changed as a group, as when changing the workpiece a correspondingly different sequence of tools is needed.
Die Anordnung baut besonders platzsparend, wenn der Wechselhalter eine Wechselplatte umfasst, an welcher die Werkzeughalterungen bzw. die Werkzeughalterung vorgesehen ist. Für einen Werkzeugwechsel braucht dann lediglich die Wechselplatte ausgewechselt zu werden. Vorzugsweise sind die Werkzeughalterungen lösbar an der Wechselplatte angebracht, so dass einzelne Werkzeughalterungen auch einzeln ausgetauscht werden können. Dies ist besonders bei Verschleiß vorteilhaft.The arrangement is particularly space-saving, when the change holder a Removable plate comprises, on which the tool holders or the Tool holder is provided. For a tool change needs then only to be replaced the removable disk. Preferably the tool holders are detachably attached to the removable plate, so that individual tool holders are also exchanged individually can. This is particularly advantageous when worn.
Wird die Werkzeuganlage durch eine Oberfläche des justierbaren Keils gebildet, so kann auf ein die Werkzeuganlage umfassendes Zwischenstück zwischen Keil und Werkzeug verzichtet werden. Die hierdurch gebildete Anordnung ist zum einen kostengünstiger und zum anderen platzsparender als die Anordnungen nach dem Stand der Technik.Is the tool attachment through a surface of the adjustable wedge formed, so can on a tool plant comprehensive adapter waived between wedge and tool. The thus formed Arrangement is on the one hand cheaper and on the other hand space-saving as the arrangements of the prior art.
Vorzugsweise ist die Verstellrichtung, entlang welcher der Keil bedingt durch die Keilführung justierbar ist, mit einem Winkel < 90o bezüglich der Justierrichtung geneigt. Auf diese Weise können entsprechende Verstellmittel für den Keil in einen Bereich der Werkzeughalterung gelegt werden, der in seiner Höhe abnimmt. Hierbei ist der Begriff "Höhe" senkrecht zur Stempelachse zu verstehen. Dieser Bereich ist in der Regel leicht zugänglich und muss darüber hinaus bei jedem Werkzeughalter vorgesehen sein, so dass für die Verstellmittel kein zusätzlicher Bauraum benötigt wird. Insofern ist durch einen derartigen von 90o abweichenden Winkel eine weitere Bauraumreduktion möglich. Es versteht sich, dass der Winkel zwischen Verstellrichtung und Justierrichtung, welcher diese Bauraumreduktion ermöglicht, auch unabhängig von den übrigen Merkmalen des Werkzeughalters vorteilhaft ist.Preferably, the adjustment, along which the wedge conditional is adjustable by the wedge guide, with an angle <90o with respect to the Adjustment direction inclined. In this way, appropriate adjustment for the wedge to be placed in an area of the tool holder, which decreases in height. Here, the term "height" is perpendicular to Stamp axis to understand. This area is usually easily accessible and must also be provided with each tool holder, so that no additional space is needed for the adjustment. insofar is another by another such 90o angle Space reduction possible. It is understood that the angle between Adjustment and adjustment, which this space reduction allows, regardless of the other features of the tool holder is advantageous.
Weitere Vorteile, Ziele und Eigenschaften vorliegender Erfindung werden anhand anliegender Zeichnung erläutert, in welcher beispielhaft ein erfindungsgemäßer Werkzeughalter dargestellt ist.Further advantages, objects and features of the present invention will be explained with reference to the accompanying drawing, in which an exemplary inventive Tool holder is shown.
