Description
Die Erfindung betrifft einen Werkzeugschieber.The invention relates to a tool slide.
Werkzeugschieber, welche auch Keiltriebe genannt werden, sind bekannt.Tool slides, which are also called wedge drives, are known.
Keiltriebe werden in Werkzeugen in der Metallbearbeitung, z.B. bei Umformpressen eingesetzt. Verbunden mit diesen Keiltrieben sind üblicherweise Einrichtungen bzw. Werkzeuge, die ein Stanzen oder anderweitiges Verformen ermöglichen. Ein üblicher Keiltrieb besitzt ein oberes Führungsteil umfassend ein Schieberelement und ein Schieberführungselement und einen unteren Führungsteil umfassend ein Treiberelement bzw. umgekehrt. Die Keiltriebe werden seitens des Schieberführungselements durch einen eine im Allgemeinen vertikale Presskraft aufbringenden Antrieb bewegt. Seitens des Treiberelements sind Keiltriebe in dem Werkzeug bzw. der Presse auf einer Grundplatte befestigt, auf der auch das zu bearbeitende Werkstück direkt oder über eine entsprechende Auflageeinrichtung aufgelegt ist.Wedge drives are used in tools in metalworking, e.g. used in forming presses. Associated with these wedge drives are usually facilities or tools that allow punching or otherwise deforming. A conventional wedge drive has an upper guide part comprising a slider element and a slider guide element and a lower guide part comprising a driver element and vice versa. The wedge drives are moved by the slider guide element by a drive applying a generally vertical pressing force. On the part of the driver element wedge drives are mounted in the tool or the press on a base plate on which the workpiece to be machined is placed directly or via a corresponding support device.

Üblicherweise bestehen oben hängende Keiltriebe, die in der Karosserieindustrie verwendet werden, aus einem Treiber, einem Schieber und einer Schieberaufnahme. Auf die Oberseite der Schieberaufnahme wirkt eine senkrechte Kraft, die die Schieberaufnahme nach unten drückt. Der Treiber ist im Werkzeug fest verankert, so dass beim Druck auf die Schieberaufnahme der in der Schieberaufnahme verankerte Schieber in eine beliebige Richtung außerhalb der senkrechten Arbeitsrichtung gedrückt wird.Usually, overhead wedge drives used in the body industry consist of a driver, a slider, and a slider receiver. On the top of the slider recording acts a vertical force that pushes the slider recording down. The driver is firmly anchored in the tool, so that when pressing on the slide holder, the slide anchored in the slide holder is pushed in any direction outside the vertical working direction.
Häufig werden oben hängende Keiltriebe eingesetzt. Bei dieser Bauart hängt der Schieber in seiner Führung beweglich in der Schieberaufnahme. Der Treiber sitzt starr im Unterteil und gibt die Arbeitsrichtung des Schiebers vor. Beim Abwärtshub der Presse setzt der ausgefederte Schieber auf den Treiber auf und wird von der weiterlaufenden Schieberaufnahme über die Treiberfläche in Arbeitsrichtung geschoben.Frequently, overhead wedge drives are used. In this design, the slider depends in his leadership movable in the slide holder. The driver sits rigidly in the lower part and specifies the working direction of the slider. During the downward stroke of the press, the spring-loaded slider sets on the driver and is pushed by the continuing slide holder over the driver surface in the working direction.
Die aus diesem Stand der Technik bekannten Keiltriebe weisen Nachteile auf, so dass die eingesetzten Schieber häufig nur kurze Standzeiten besitzen und aufgrund ihres konstruktiven Aufbaus hohem Verschleiß ausgesetzt sind. Sie müssen daher häufig bereits nach kurzen Laufzeiten ausgetauscht werden, weil sie Verschleißerscheinungen zeigen, so dass eine exakte Umlenkung der vertikalen Presskräfte nicht mehr möglich ist, was bei der Metallbearbeitung zu nicht akzeptablen Toleranzen führt.The known from this prior art wedge drives have disadvantages, so that the slide used often have short lives and are exposed due to their structural design high wear. Therefore, they often need to be replaced after a short period of time because they show signs of wear, so that an exact Redirecting the vertical pressing forces is no longer possible, which leads to unacceptable tolerances in metalworking.

Ferner wird ausgeführt, dass die lineare Führung in der Schieberelementaufnahme das bewegbare Schieberelement spielfrei führen soll und dabei hohe Pressenkräfte ertragen und hohe Standzeiten realisieren muss. Als Toleranz der Laufgenauigkeit des bewegbaren Schieberelements wird eine Toleranz von 0,02 mm angegeben.Furthermore, it is stated that the linear guide in the slide element holder is intended to guide the movable slide element without play and in the process must endure high press forces and realize long service life. As a tolerance of the running accuracy of the movable slide element, a tolerance of 0.02 mm is specified.
Wie bereits im Stand der Technik auch ausgeführt, bestehen derartige Keiltriebe bzw. Schieber aus einer Schieberbaugruppe, welche wiederum aus einem Treiber, einem Schieberteil und einem Schieberbett besteht. Hierbei ist das Schieberteil mit Halteelementen am Schieberbett befestigt, wobei das Schieberteil zwischen Treiber und Schieberbett gleitend aufgehängt ist. Entsprechende Schrägen an Schieberbett und Treiber sind derart gegensinnig geneigt angeordnet, dass das Schieberteil beim Zusammenfahren von Schieberbett und Treiber zwischen beiden Teilen "herausgedrückt" wird. Da, wie bereits ausgeführt, hierbei sehr große Kräfte wirken, muss eine entsprechende Führung vorgesehen sein.As already stated in the prior art, such wedge drives or slides consist of a slide assembly, which in turn consists of a driver, a slide part and a slide bed. In this case, the slide part is fastened with retaining elements on the slide bed, wherein the slide part between the driver and slide bed is slidably suspended. Corresponding bevels on slide bed and driver are arranged inclined in opposite directions, so that the slide member "pushed out" when moving together slide valve and driver between the two parts. Since, as already stated, in this case act very large forces, a corresponding guide must be provided.
Die bekannten Führungen sind hierbei die Deckleistenführung, die Führung mit Führungsklammern, die Führung mit Führungssäulen und die Schwalbenschwanzführung (
Der überwiegende Teil dieser Führungen ist an der Außenfläche des Schiebers angebracht. Hierbei muss festgestellt werden, dass die Kraftübertragung und die Führung nicht optimal sind.The majority of these guides are attached to the outer surface of the slider. It must be noted that the power transmission and the leadership are not optimal.
Einerseits muss die Hauptschieberführung über die Gleitflächen hierdurch nach innen versetzt ausgeführt werden, so dass weniger Kraftübertragung möglich ist. Zudem ergibt sich häufig ein hoher Platzbedarf und es konnten Verformungen durch Einleiten von Betriebskräften (Arbeits- und Rückzugskräfte) festgestellt werden.On the one hand, the main slide guide on the sliding surfaces must be carried out thereby offset inwards, so that less power transmission is possible. In addition, often results in a high space requirement and it could be found deformations by initiating operating forces (work and withdrawal forces).
Bei der bekannten Schwalbenschwanzführung ist von Nachteil, dass hierbei relativ häufig das Spiel nachgearbeitet werden muss, was bedeutet, dass der Schieber komplett deinstalliert werden muss. Auch bei allen anderen Schiebern ist die Montage und Demontage sehr komplex und aufwändig. Diese kann einerseits nur nach hinten im gesamten Schieberkörper durchgeführt werden, wobei insbesondere bei großen Schiebern aufgrund des hohen Gewichts des Schieberkörpers und der stark beschränkten Bauräume große Massen in eng gestellter Führung unter Zuhilfenahme eines Krans bewegt werden müssen. Bei Klammerschiebern muss seitlicher Bauraum für die Montage und Demontage vorgesehen werden, so dass eine optimierte Stellung der Schieber für bestimmte Anwendungen nicht sicher gewährleistet ist.In the known dovetail guide has the disadvantage that this relatively often the game must be reworked, which means that the slide must be completely uninstalled. Even with all other sliders, the assembly and disassembly is very complex and expensive. On the one hand, this can only be carried out to the rear in the entire slider body, with large masses having to be moved in close alignment with the aid of a crane, especially in the case of large sliders, due to the high weight of the slider body and the greatly limited installation space. In the case of clip-type slides, lateral installation space must be provided for assembly and disassembly, so that an optimized position of the slides is not guaranteed for certain applications.
Aus der
Aufgabe der Erfindung ist es, ein Verfahren zum Ausgleich eines fertigungsbedingten Versatzes zwischen einem Schiebekörper und dem Treiber zu schaffen.The object of the invention is to provide a method for balancing a production-related offset between a sliding body and the driver.
Die Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.The object is achieved with the features of claim 1.
Erfindungsgemäß ist die Schieberführung zwischen Schieberkörper und Schieberbett schienen- oder stegartig ausgebildet. Der Steg kann insbesondere prismenförmig, insbesondere schwalbenschwanzförmig ausgebildet sein. Ergänzend zu der prismenförmigen bzw. schwalbenschwanzförmigen Ausführung ist jedoch erfindungsgemäß das Führungsspiel durch eine Keilfläche einstellbar, wobei hierfür ein gesondertes Gleitelement vorgesehen ist.According to the slider guide between slide body and slide bed rail or web-like design. The web may in particular be prism-shaped, in particular dovetail-shaped. In addition to the prism-shaped or dovetail-shaped embodiment, however, according to the invention the guide play can be adjusted by a wedge surface, for which purpose a separate sliding element is provided.
Im Einzelnen wird diese Führung bei einer bekannten Schieberbaugruppe, welche aus Treiber, Schieberteil und Schieberbett besteht, angewendet, wobei das Schieberteil im Schieberbett gleitend aufgehängt ist. Zwischen dem Treiber und dem Schieberteil sind Gleitpaarungen angeordnet.Specifically, this guide is applied to a known slide assembly consisting of driver, slide part and slide bed, the slide part in the slide bed is hung in a sliding manner. Between the driver and the slide part sliding pairings are arranged.
Bei einer stegartigen Feder, die in die korrespondierende Nut ragt, und insbesondere prismenförmigen bzw. schwalbenschwanzförmigen Stegen, besitzt beispielsweise das Schieberbett die Ausnehmung zur Aufnahme der Feder, wobei außenseitig an der Feder und auf der eigentlichen Gleitfläche ein Gleitelement ausgebildet ist. Das Gleitelement ist mit einer keilförmigen Fläche bzw. Schräge ausgebildet. Diese Schräge bzw. Keilform kann hierbei geringfügig keilartig an der nutseitigen Fläche eines L-förmigen Gleitelements ausgebildet sein, dann ist die Nut mit einer korrespondierenden Fläche, insbesondere einer korrespondierenden schrägen Fläche ausgebildet. Hierbei können beide Gleitelemente oder nur ein Gleitelement geringfügig keilartig ausgebildet sein und die Schräge bzw. keilförmige Fläche aufweisen. Der Schieber zentriert sich durch das Führungsprisma am Treiber in der Lage im Werkzeug - die Gleitelemente zwischen Schieberteil und Schieberbett werden auf die zentrierte Lage des Schieberteils angepasst. Durch Verschieben des Gleitelements entlang der Richtung der Schräge (üblicherweise in Längsrichtung der langgestreckten Gleitleisten) wird das Führungsspiel zwischen dem Schieberbett und dem Schieberkörper verändert, d.h. insbesondere verkleinert.In a web-like spring which projects into the corresponding groove, and in particular prism-shaped or dovetailed webs, for example, the slide bed has the recess for receiving the spring, wherein on the outside of the spring and on the actual sliding surface, a sliding element is formed. The sliding element is formed with a wedge-shaped surface or bevel. This bevel or wedge shape can here be formed slightly wedge-like on the groove-side surface of an L-shaped sliding element, then the groove is formed with a corresponding surface, in particular a corresponding inclined surface. Here, both sliding elements or only one sliding element may be formed slightly wedge-like and have the slope or wedge-shaped surface. The slide centered by the guide prism on the driver in the position in the tool - the sliding elements between the slide part and slide bed are adapted to the centered position of the slide part. By sliding the sliding element along the direction of the slope (usually in the longitudinal direction of the elongated sliding strips), the guiding play between the sliding bed and the slider body is changed, i. especially reduced.
Das L-förmige Gleitelement kann hierbei auch aus flachen Einzelgleitelementen, die L-förmig zueinander stehen, ausgebildet sein.The L-shaped sliding element may in this case also be formed from flat individual sliding elements, which are L-shaped with respect to each other.
Insbesondere in dem Fall, in dem beide Gleitelemente die Schräge aufweisen, kann durch gegensinniges Verschieben der Gleitleisten die Justierung des Schieberbetts zum Schieberkörper erzielt werden.In particular, in the case in which both sliding elements have the slope, the adjustment of the slide bed to the slider body can be achieved by oppositely moving the slide strips.

Ein erfindungsgemäßer Werkzeugschieber 1 besitzt ein Schieberbett 2, einen Schieberkörper 3 und einen Treiber 4.An inventive tool slide 1 has a
Das Schieberteil 3 ist am Schieberbett 2 im gezeigten Fall hängend angeordnet, wobei das Schieberteil 3 vom Treiber 4 abhebbar ist. Der Treiber 4 ist üblicherweise in einer ersten (im gezeigten Fall der unteren) Werkzeughälfte angeordnet, während das Schieberteil 3 über das Schieberbett 2 an einer korrespondierenden zweiten (oberen) Werkzeughälfte (nicht gezeigt) angeordnet ist.The
Das Schieberbett 2 ist in etwa kastenförmig ausgebildet und besitzt eine länglich rechteckige Nut 5, wobei neben der länglich rechteckigen Nut 5 Schraublöcher 6 für die Aufnahme von entsprechenden Schrauben (nicht gezeigt) vorgesehen sind. Die Nut und die benachbarten, die Nut begrenzenden Flächen 7 bilden eine Auflagefläche für L-förmige Gleitleisten 8, welche auf den Flächen 7 aufliegen und sich mit einem L-Schenkel 9 in die Nut hineinerstrecken. Die L-förmigen Gleitleisten 8 besitzen Montagelöcher 10 zum Einschrauben von Montageschrauben zur Anordnung in den Schraublöchern 6.The
Die L-förmigen Gleitleisten 8 besitzen zur Nutmitte hin weisende divergierende Flächen 11, mit denen sie einen prismatischen Zwischenraum zwischen sich begrenzen. Zum Schieberkörper 3 hin besitzen die L-förmigen Gleitleisten 8 Gleitflächen 12, welche eben und bezüglich einer gezeigten X-Achse 13 senkrecht ausgebildet sind.The L-shaped sliding
Der Schieberkörper 3 besitzt zu den Flächen 12 hin korrespondierende Gleitflächen bzw. Gleitleisten 14, welche als Gleitpartner zu den L-förmigen Gleitleisten 8 ausgebildet sind.The
Symmetrisch zur Hochachse erstreckt sich zwischen den Gleitleisten 14 als Feder 15 ein Führungsteil 15 oder Führungssteg 15 nach oben in die Nut 5 hinein. Der Führungssteg 15 hat insbesondere einen prismatischen Querschnitt. Der Führungssteg 15 besitzt dabei langgestreckte prismatische Flächen 16, mit denen er an den Flächen 11 der L-förmigen Gleitleisten 8 anliegen kann.Symmetrically to the vertical axis extends between the sliding
Dem Treiber zugewandt besitzt der Schieberkörper weitere Gleitleisten 17, welche bezogen auf die X-Achse 13 schräg angeordnet sind und mit prismatischen Gleitflächen 18 des Treibers 4 korrespondieren. Die Leisten 17 bilden, da sie mit dem Schieberkörper verbunden sind, abhebbare Gleitleisten, welche beim Zusammenfahren des Werkzeugoberteils und des Werkzeugunterteils in Wirkverbindung mit den Flächen 18 mitgebracht werden.Facing the driver, the slider body has further slide strips 17, which are arranged obliquely with respect to the
Da die Führungsflächen der L-förmigen Gleitleisten 8 und die korrespondierenden Flächen 12 der Leisten 14 in Bezug auf die X-Achse 13 senkrecht angeordnet sind und auch senkrecht zum Führungssteg 15 angeordnet sind, spricht man bei dieser Ausführungsform von einer sogenannten Flachführung.Since the guide surfaces of the L-shaped slide strips 8 and the corresponding surfaces 12 of the
Die dachartig schräg gestellten korrespondierenden Gleitelemente 17, 18 zwischen Schieberkörper und Treiber bilden eine sogenannte Prismenführung.The roof-like inclined corresponding sliding
Da eine exakte Passung und Führung der Werkzeugschieber insbesondere zwischen dem Schieberbett und dem Schieberkörper notwendig ist, muss die Führung des Schieberkörpers im Schieberbett einstellbar sein bzw. müssen die Gleitleisten 8 und der Führungssteg 15 aufeinander eingestellt werden.Since an exact fit and guidance of the tool slide, in particular between the slide bed and the slider body is necessary, the leadership of the slider body in the slide bed must be adjustable or the slide strips 8 and the
Hierzu sind (
Das Verschieben der Gleitleisten 8 entlang der Richtung 21 ändert noch nichts an gegebenenfalls vorhandenen Spalten oder Abständen zwischen den Oberflächen der Gleitleisten 8 bzw. der L-Schenkel 9 und der Flächen 16 des Führungsstegs 15. Bezogen auf die Längserstreckung bzw. die Richtung 21 verlaufen daher Anlageflächen 22 der L-Schenkel 9 der L-förmigen Gleitleisten 8 am Schieberbett 2 schräg. Das bedeutet, dass die kurzen L-Schenkel 9, welche in die Nut 5 ragen, bezogen auf die Richtung 21 geringfügig keilartig ausgebildet sind und bezogen auf die Längserstreckung ihre Dicke ändern. Die Keilform bzw. Schräge besitzt beispielsweise eine Steigung von 1-5 Grad.The displacement of the slide strips 8 along the direction 21 does not change any existing gaps or distances between the surfaces of the slide strips 8 and the L-leg 9 and the
Die Anlageflächen 11 an den L-Schenkeln 9 der L-förmigen Gleitleisten 8 sind zu entsprechenden korrespondierenden Flächen 16 des Führungsstegs 15 gerichtet.The contact surfaces 11 on the L-legs 9 of the L-shaped sliding
Zum Einstellen des Spiels sind zudem die Nutseitenwandungen 19 mit korrespondierenden Anschrägungen bzw. keilartig schräg ausgebildet. Eine Verschiebung entlang der Richtung 21 bewirkt somit, dass die Gleitleisten 8 zum Führungssteg 15 hinbewegt werden oder von diesem wegbewegt werden. Da dies gleichzeitig auf eine Annäherung der Gleitleisten bzw. Entfernung der Gleitleisten in Querrichtung, d.h. der Richtung 23, bewirkt, sind die Langlöcher 10 so ausgebildet, dass eine schwimmende Lagerung auch in Richtung 23 um die Schrauben 20 herum ermöglicht wird.To adjust the game, the groove side walls 19 are also formed obliquely with corresponding chamfers or wedge-like. A displacement along the direction 21 thus causes the slide strips 8 are moved toward the
Ein Verschieben entlang der Richtung 21 bewirkt somit, dass aufgrund der korrespondierenden schrägen Flächen 19/22 der Abstand zwischen den L-Schenkeln 9 und den Flächen 16 verringert bzw. beseitigt wird. Hierbei können sowohl beide Gleitleisten 8 als auch nur eine Gleitleiste 8 bewegt werden.A displacement along the direction 21 thus causes, due to the corresponding inclined surfaces 19/22, the distance between the L-legs 9 and the
Um die Gleitleisten 8 an den Führungssteg 15 anzupassen und damit auch die exakte Position des Schieberkörpers im Schieberbett anzupassen, kann beispielsweise von einer Anschlagposition der Schrauben 20 in den Langlöchern 10 (
Werden nun die L-förmigen Gleitleisten 8 entsprechend der Richtung 21 verschoben (
Wie bereits ausgeführt, kann dies genutzt werden, um einen fertigungsbedingten Versatz zwischen dem Schieberbett mit Schieberteil im Schieberoberteil und dem Treiber im Unterteil einzustellen (
Hierzu wird das Schieberbett mit Schieberteil mit Spiel zwischen den Gleitleisten 8 und dem Führungssteg 15 am Werkzeug montiert. Die Spaltmaße zwischen den korrespondierenden Flächen 11 der L-Schenkel 9 und 16 des Führungsstegs 15 besitzen dabei jeweils einen Spalt mit einem Spaltmaß, das von der Neigung der Schräge, den Fertigungstoleranzen und der Stellung der Schieberteile zueinander abhängt. Nach dem Aufsetzen der Gleitleisten 17 auf dem Treiber 4 wird ein fertigungsbedingter Versatz zwischen dem Schieberbett mit Schieberteil und dem Treiber ausgeglichen. Der Schieber zentriert sich selbst. In diesem zentrierten Zustand lassen sich anschließend die L-förmigen Gleitleisten 8 noch weiter verschieben, sodass schließlich in aufgesetztem Zustand das Führungsspiel bzw. die Spaltmaße beseitigt sind. Hierdurch wird sichergestellt, dass auch im zusammengefahrenen Zustand der Presse durch die verschiebbaren Gleitleisten geringste Toleranzen eingestellt sind.For this purpose, the slide bed is mounted with slide part with clearance between the slide strips 8 and the
Das so eingestellte Führungsspiel wird noch im zusammengefahrenen, zentrierten Zustand durch eine Fixiereinrichtung 26 gesichert. Das Führungsspiel verändert sich dadurch beim Öffnen des Werkzeuges und damit des Werkzeugschiebers nicht mehr.The thus set guide game is still secured in the contracted, centered state by a fixing
Eine solche Fixiereinrichtung 26 ist in unterschiedlichen Ausführungen beispielhaft in den
Bei der Erfindung ist von Vorteil, dass durch die einstellbaren Gleitleisten und deren L-förmige Form einerseits und der prismatische Führungssteg 15 auf der anderen Seite eine sehr kompakte, aber auch sehr stabile Führung des Schieberkörpers 3 im Schieberbett 2 erzielt wird und zudem in einfacher Weise geringste Toleranzen einstellbar sind.In the invention it is advantageous that a very compact, but also very stable guidance of the
Die Erfindung betrifft ein Verfahren zum Ausgleich eines fertigungsbedingten Versatzes bei einem Werkzeugschieber, insbesondere einem Werkzeugschieber, wobei der Werkzeugschieber ein Schieberbett 2, einen Schieberkörper 3 und einen Treiber 4 umfasst, wobei zwischen dem Schieberkörper 3 und dem Treiber 4 eine selbstzentrierende Führung ausgebildet ist, welche beim Aufsetzen des Schieberkörpers 2 auf den Treiber 4 den Schieberkörper 3 am Treiber 4 quer zu einer x-Achse 13 zentriert und der Schieberkörper 3 am Schieberbett 2 über eine Flachführung quer zur x-Achse schwimmend derart gelagert ist, dass der fertigungsbedingte Versatz beim Zentrieren des Schieberkörpers 3 auf dem Treiber 4 in Querrichtung ausgeglichen wird, wobei nach dem Ausgleich des fertigungsbedingten Versatzes Gleitelemente 8 zwischen Schieberbett 2 und Schieberkörper 3 verschoben und derart justiert werden, dass die Gleitflächen formschlüssig an einem in eine Nut 5 entsprechend der x-Achse 13 ragenden Steg 15 anliegen und damit die schwimmende Lagerung quer zur x-Achse 13 aufgehoben wird.The invention relates to a method for compensating a production-related offset in a tool slide, in particular a tool slide, wherein the tool slide comprises a
