Description
Die Erfindung betrifft eine Vorrichtung zum Befetten von Werkstücken in Band- oder Platinenform mit mehreren mit fettdurchlässigem Material versehenen, hohlen sowie parallel zueinander ausgerichteten Befettungswalzen, die auf je einer in einem Gestell angeordneten Hohlachse drehbar gelagert sind, durch welche das Befettungsmittel dem Innenraum der Befettungswalzen über eine Vielzahl von in deren Längsrichtung angeordneten, verschließbaren, radialen Befettungsmittel-Austrittsöffnungen zuführbar ist, wobei eine jede Hohlachse beidendig mit einem Formstück versehen ist, welches formschlüssig in eine entsprechend konfigurierte Ausnehmung im Gestell einsetzbar und darin mittels einer Arretierungseinrichtung lösbar gehaltert ist.The invention relates to a device for greasing of workpieces in tape or blank form with several hollow with grease permeable material as well as greasing rollers aligned parallel to each other, arranged on one in a rack Hollow axis are rotatably mounted, through which the lubricant the interior of the greasing rollers a plurality of arranged in the longitudinal direction, closable, radial lubricant outlet openings can be fed, with each hollow axis at both ends is provided with a fitting which is form-fitting in a correspondingly configured recess usable in the frame and in it by means of a locking device is releasably supported.
Eine Vorrichtung der vorbezeichneten Gattung ist in der SU-A-633 646 beschrieben. Bei der bekannten Vorrichtung ist das die obere Befettungswalze tragende obere Gestell um eine parallel zur Durchlaufebene angeordnete Schwenkachse wegklappbar. Zuvor müssen indessen zwei mit je einem Schwenkfuß versehene Flügelschrauben gelöst und entfernt werden, welche entgegen der Rückstellkraft von Schraubendruckfedern das obere Gestell gegen das untere Gestell ziehen, um auf diese Weise den Andruck zwischen den beiden Befettungswalzen, und damit die Befettungsschichtdicke, zu verändern.A device of the aforementioned type is in SU-A-633 646. In the known device is the upper greasing roller upper frame around a parallel to the flow level Swiveling axis can be folded away. Before that, however two wing screws, each with a swivel base released and removed, which counter to the restoring force the top frame of helical compression springs pull against the lower frame to Pressure between the two greasing rollers, and so to change the lubrication layer thickness.
Gemäß der SU-A-633 646 weisen die beidendigen Formstücke einer jeden Hohlachse je einen langovalen Querschnitt auf, dessen Längsachse bei in Betrieb befindlicher Vorrichtung verikal ausgerichtet, in einer korrespondierenden einseitig offenen Aussparung der beidseitigen Gestellwangen aufgenommen und mittels eines angeschraubten Befestigungsstegs in der Aussparung gesichert ist.According to SU-A-633 646, the two ends Fittings of each hollow axis have a long oval Cross section on, the longitudinal axis of which is in operation Device vertically aligned, in one corresponding one-sided open recess of the frame cheeks on both sides added and by means of a screwed fastening web in the recess is secured.
Bei einem Betrieb von Stanzen bzw. Pressen kommt es zu einer Wiederholung bestimmter Fertigungsvorgänge mit der Folge, daß bei jeweils den gleichen Werkstücken bestimmte Beölungs- bzw. Befettungsbilder periodisch in derselben Form wiederkehren. In diesem Falle ist es grundsätzlich möglich, bei der Vorrichtung gemäß der SU-A-633 646 vorhandene Befettungswalzen gegen andere Walzen auszuwechseln, welche dem jeweils gewünschten Befettungsbild entsprechen. Dieses geschieht bei der bekannten Vorrichtung so, daß zunächst die beiden Flügelschrauben gänzlich gelöst gewerden und das obere Gestell relativ zum unteren Gestell um etwa 180° weggeklappt wird. Nach Lösen von insgesamt acht Befestigungsschrauben können die vier Befestigungsstege entfernt und die beiden Befettungswalzen mit ihren Formstücken langovalen Querschnitts aus den zugehörigen Langlochaussparungen senkrecht nach oben herausgenommen werden. In analog umgekehrter Weise können sodann andere Befettungswalzen eingesetzt, die Befestigungsstege verschraubt, das obere Gestell um 180° zurückgeklappt und mittels der beiden Flügelschrauben entgegen der Rückstellkraft der Schraubendruckfedern am Untergestell befestigt werden. Diese Schilderung zeigt, daß ein betriebsbedingtes Auswechseln von Befettungswalzen bei der Vorrichtung gemäß der SU-A-633 646 recht umständlich und zeitaufwendig ist.When operating punches or presses comes there is a repetition of certain manufacturing processes with the result that the same workpieces in each case certain oiling or greasing patterns periodically in return in the same form. In this case it is in principle possible in the device according to the SU-A-633 646 existing greasing rollers against others Replace rollers that the desired Correspond to the greasing pattern. This happens at the known device so that first the two thumbscrews be completely solved and the upper frame folded away from the lower frame by about 180 ° becomes. After loosening a total of eight fastening screws the four fastening bars can be removed and the two greasing rollers with their fittings long oval cross section from the associated Elongated hole cutouts removed vertically upwards will. In the opposite way, others can then Greasing rollers used, the fastening webs screwed, the upper frame folded back by 180 ° and by means of the two wing screws against the Resetting force of the helical compression springs on the base frame be attached. This description shows that an operational Replacement of greasing rollers at the device according to SU-A-633 646 quite cumbersome and is time consuming.
Ausgehend von der Vorrichtung gemäß der SU-A-633 646, liegt der Erfindung die Aufgabe zugrunde, die bekannte Vorrichtung so abzuändern, daß diese in zeitsparender Weise durch Auswechseln ihrer Befettungswalzen mit wenigen Handgriffen umgerüstet werden kann. Entsprechend der Erfindung wird diese Aufgabe dadurch gelöst, daß die Hohlachse in Förderrichtung oder entgegengesetzt dazu in einer zur Durchlaufebene des Werkstückes parallel verlaufenden Ebene oder in einer zur Durchlaufebene der Werkstücke schräg verlaufende Ebene in die Ausnehmungen im Gestell einsetzbar ist, wobei die Hohlachse mit ihren Formstücken gegen eine andere Hohlachse nach Art einer Schublade auswechselbar ist.Starting from the device according to SU-A-633 646, the invention is based on the object change known device so that this in time-saving way by changing their greasing rollers can be converted in just a few steps. According to the invention, this object solved that the hollow axis in the conveying direction or opposite for this purpose in a to the pass plane of the workpiece parallel plane or in a to Pass plane of the workpieces inclined plane can be inserted into the recesses in the frame, wherein the hollow axis with its fittings against another Hollow axis is interchangeable like a drawer.
Mit dem erfindungsgemäßen Gesamtaustausch der Hohlachse einschließlich der auf ihr befindlichen Befettungswalzen werden die Umrüstarbeiten auf ein Mindestmaß beschränkt und bei geänderten Befettungsbildern ein erneuter rascher Wechsel von Hohlachsen mit Befettungswalzen unterschiedlicher Befettungsbilder sichergestellt.With the total exchange of the invention Hollow axis including the greasing rollers on it the retrofitting work to a minimum limited and with changed greasing patterns another quick change of hollow axles with greasing rollers different lubrication patterns ensured.
Nach einer von der Erfindung bevorzugten Ausführungsform ist die Hohlachse in Förderrichtung oder entgegengesetzt dazu in einer zur Durchlaufebene des Werkstücks parallel verlaufenden Ebene in die Ausnehmung im Gestell einsetzbar. Hierbei ist eine jede Hohlachse mit ihren darauf befindlichen Befettungswalzen nach Art einer Schublade gegen eine andere Hohlachse mit Befettungswalzen eines anderen Befettungsbildes auswechselbar. Jedoch muß dieser Auswechselvorgang nicht unbedingt in einer zur Durchlaufebene des Werkstückes parallel verlaufenden Ebene erfolgen.According to a preferred embodiment of the invention is the hollow axis in the conveying direction or opposite for this purpose in a to the pass plane of the workpiece parallel plane in the recess in Frame can be used. Each hollow axis is included their greasing rollers on it like a Drawer against another hollow axis with greasing rollers another greasing pattern can be exchanged. However, this replacement process is not essential in a parallel to the flow plane of the workpiece level.
Nach einer weiteren vorteilhaften Ausführungsform kann die Hohlachse mit ihren Formstücken in einer zur Durchlaufebene der Werkstücke beliebig schräg verlaufenden Ebene in entsprechend im Gestell angeordnete Ausnehmungen eingesetzt werden.According to a further advantageous embodiment can the hollow axis with their fittings in one Passage level of the workpieces inclined at any angle Level in the frame accordingly arranged recesses are used.
Welche dieser Ausführungsformen gewählt wird, hängt im wesentlichen von der Zugänglichkeit der Hohlachsen mit ihren Formstücken zu den Gestellen sowie von der Lage der Arretierungseinrichtungen ab, die möglichst frei und rasch zugänglich sein sollten.Which of these embodiments is chosen depends essentially on the accessibility of the Hollow axes with their fittings to the frames as well depending on the location of the locking devices, if possible should be free and quickly accessible.
Auch bei der Ausbildung der Formstücke sind verschiedene Ausführungsformen möglich.The shape of the fittings is also different Embodiments possible.
Nach einer ersten Ausführungsform sind die Formstücke an den beiden Enden der Hohlachse und die entsprechenden Ausnehmungen im Gestell quader- oder würfelförmig ausgebildet. Um eine gewünschte, stets zu einer bestimmten Richtung hin und somit radial ausgerichtete Lage der Befettungsmittel-Austrittsöffnungen zu gewährleisten, erweist es sich als besonders vorteilhaft, die Formstücke an den beiden Enden der Hohlachse sowie die entsprechenden Ausnehmungen im Gestell derart unterschiedlich auszubilden, daß stets nur der gewünschte Einsatz mit entsprechend ausgerichteter Lage der Befettungsmittel-Austrittsöffnungen gewährleistet ist und andernfalls erst gar kein Einsatz der Formstücke in die Ausnehmungen möglich ist.According to a first embodiment, the fittings at the two ends of the hollow axis and the corresponding Recesses in the frame cuboid or cube-shaped educated. To a desired one, always one certain direction and thus radially aligned Location of the lubricant outlet openings guarantee, it proves to be particularly advantageous the fittings at the two ends of the hollow axis as well as the corresponding recesses in the frame train differently, that only the desired one Use with an appropriately aligned position the lubricant outlet openings guaranteed is and otherwise no use of the fittings into the recesses is possible.
In Verfolgung jener Absicht erweist es sich als besonders vorteilhaft, die Formstücke und die entsprechenden Ausnehmungen in dem Gestell an einem Ende halbkreisförmig auszubilden und mit daran kontinuierlich anschließenden, zueinander parallelen, ebenen Flächen zu versehen, die auch in unterschiedlichen Abständen zueinander verlaufen und beispielsweise auf der linken Seite der Hohlwalze mit einem größeren und auf der rechten Seite der Hohlwalze mit einem geringeren Abstand versehen sind. Dadurch gibt es nur eine Einschubmöglichkeit der Formstücke in die Ausnehmungen und damit stets die gewünschte Umfangsorientierung der Befettungsmittel-Austrittsöffnungen in der Hohlachse zu den Befettungswalzen.In pursuit of that intention, it turns out to be particularly advantageous, the fittings and the corresponding Recesses in the frame semi-circular at one end train and with it continuously adjoining, mutually parallel, flat surfaces to be provided, even at different intervals to each other and for example on the left Side of the hollow roller with a larger one and on the right side of the hollow roller with a smaller distance are provided. This means that there is only one slot the fittings in the recesses and thus always the desired circumferential orientation of the lubricant outlet openings in the hollow axis to the Greasing rollers.
In Weiterbildung der Erfindung besteht die Arretierungseinrichtung aus durch Bohrungen im Gestell hindurchgreifenden Schrauben mit Außen- oder Innensechskant- oder mit Schlitzkopf, welche mit ihrem Außengewinde in ein entsprechendes Innengewinde der Bohrungen eingreifen und an mindestens einer Fläche das Formstück klemmend arretieren. Dabei können an jedes Formstück auch mehrere Schrauben zur Arretierung angreifen.In a development of the invention, the locking device from reaching through holes in the frame Screws with external or internal hexagon head or with slotted head, which with their external thread in a corresponding internal thread of the holes intervene and the fitting on at least one surface lock with a clamp. You can use any fitting also attack several screws for locking.
