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.The invention relates to a device for greasing workpieces in band or plate form with a plurality of grease-permeable material, hollow and parallel to each other greasing rollers, which are rotatably mounted on a hollow shaft arranged in a frame, through which the greasing agent over the interior of the greasing rollers a plurality of closable, radial greasing agent outlet openings arranged in their longitudinal direction can be fed.

Eine bekannte Vorrichtung dieser Art ist aus der DE 35 07 846 C1 bekanntgeworden. Diese Vorrichtung weist zur axial-selektiven Beaufschlagung der Befettungswalzen eine Vielzahl von in ihrer Längsrichtung hintereinander angeordneten, verschließbaren radialen Befettungsmittel-Austrittsöffnungen auf, zu denen die Befettungswalzen längs ihrer Hohlachsen verschiebbar angeordnet sind.A known device of this type has become known from DE 35 07 846 C1. For axially selective loading of the greasing rollers, this device has a plurality of closable radial greasing agent outlet openings arranged one behind the other in their longitudinal direction, to which the greasing rollers are arranged so as to be displaceable along their hollow axes.

Bei dieser Vorrichtung können durch Verschließen und Wiederöffnen der Befettungsmittel-Austrittsöffnungen sowie durch ein Verschieben und Wiederarretieren der Befettungswalzen auf den Hohlachsen axial-selektive Befettungen vorgenommen werden.In this device, axially selective greasing can be carried out by closing and reopening the greasing agent outlet openings and by moving and re-locking the greasing rollers on the hollow axes.

Zuvor müssen in den gewünschten, innerhalb der betreffenden Befettungswalze gelegenen Abschnitten die Dichtungsschrauben der dort befindlichen Befettungs-Austrittsöffnungen gelöst werden. Um eine weitgehende Freiheit der Einstellbarkeit zu gewährleisten, wird vorteilhaft die Summe der Länge der auf einer Hohlachse angeordneten Befettungswalzen etwa 1/2 bis 2/3 so groß wie die gesamte nutzbare Länge der Hohlachsen bemessen. Dadurch verbleibt zur Erzielung unterschiedlicher Befettungsbilder ein entsprechend großer gewünschter Spielraum zur Verschiebung der Befettungswalzen auf den Hohlachsen. Dabei sind die Befettungsmittel-Austrittsöffnungen bei einem Drucköler an der Oberseite und bei einem Tropföler zur Unterseite der Hohlachsen hin geöffnet.Before this, the sealing screws of the greasing outlet openings located there must be in the desired sections located within the greasing roller concerned be solved. In order to ensure extensive freedom of adjustability, the sum of the length of the greasing rollers arranged on a hollow axis is advantageously dimensioned to be approximately 1/2 to 2/3 as large as the total usable length of the hollow axes. This leaves a correspondingly large desired scope for shifting the greasing rollers on the hollow axes to achieve different greasing patterns. The lubricant outlet openings are open at the top of a pressure oiler and at the bottom of the hollow axes in the case of a drip oiler.

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 Fall müssen bei der vorbekannten Vorrichtung die Befettungswalzen entsprechend dem gewünschten Befettungsbild auf den Hohlachsen verschoben und wieder arretiert werden sowie die hierzu erforderlichen Befettungsmittel-Austrittsöffnungen geschlossen bzw. geöffnet werden. Diese Umstellung erfordert trotz ihrer Vorteile stets zeitaufwendige Umrüstungsarbeiten.In the operation of punches or presses, certain manufacturing processes are repeated, with the result that certain oiling or greasing patterns recur periodically in the same form for the same workpieces. In this case, in the previously known device, the greasing rollers have to be moved on the hollow axles in accordance with the desired greasing pattern and locked again, and the greasing agent outlet openings required for this purpose have to be closed or opened. Despite its advantages, this changeover always requires time-consuming conversion work.

Von diesem Stand der Technik ausgehend, liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Gattung zu schaffen, welche in der vorbeschriebenen Betriebsweise wiederkehrende bzw. identische Beölungs- bzw. Befettungsbilder derart berücksichtigt, daß die Vorrichtung in zeitsparender Weise sowie mit wenigen Handgriffen umgerüstet werden kann.Starting from this prior art, the invention has for its object to provide a device of the type mentioned, which takes into account the recurring or identical oiling or greasing images in such a way that the device in a time-saving Way and can be converted in a few easy steps.

Diese Aufgabe wird in Verbindung mit dem eingangs genannten Gattungsbegriff erfindungsgemäß dadurch gelöst, daß 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.This object is achieved in connection with the generic term mentioned at the outset in that each hollow axis is provided at both ends with a shaped piece which can be inserted in a form-fitting manner in a correspondingly configured recess in the frame and is detachably held therein by means of a locking device.

Durch diese Anordnung kann eine jede Hohlachse mit ihren darauf befindlichen Befettungswalzen insgesamt rasch aus dem Gestell entfernt und durch eine neue Hohlachse mit neuen Befettungswalzen ersetzt werden, welche einerseits mit den entsprechenden Formstücken an ihrer zugeordneten Hohlachse in das Gestell eingesetzt werden können und in ihrer Anordnung auf der Hohlachse das jeweils gewünschte Befettungsbild ergeben.With this arrangement, each hollow axle with its greasing rollers located thereon can be quickly removed from the frame and replaced by a new hollow axle with new greasing rollers, which can be inserted into the frame with the corresponding fittings on their assigned hollow axis and in their arrangement the desired greasing pattern of the hollow axis.

Mit diesem 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 this complete exchange of the hollow axle including the greasing rollers located on it, the conversion work is kept to a minimum and, if the greasing patterns are changed, a new rapid change of hollow axes with greasing rollers with different greasing patterns is ensured.

Nach einer ersten vorteilhaften Ausführungsform ist die Hohlachse in Förderrichtung oder entgegengesetzt dazu in einer zur Durchlaufebene des Werkstückes 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 first advantageous embodiment, the hollow axis can be inserted into the recess in the frame in the conveying direction or in the opposite direction in a plane running parallel to the passage plane of the workpiece. Each hollow axis is included their greasing rollers located there can be exchanged in the manner of a drawer for another hollow axis with greasing rollers of a different greasing pattern. However, this replacement process does not necessarily have to take place in a plane running parallel to the passage plane of the workpiece.

Nach einer weiteren vorteilhaften Ausführungsform kann die Hohlachse mit ihren Formstücken in einer zur Durchlaufebene der Werkstücke beliebig schräg verlaufenden, auch senkrechten, Ebene in entsprechend im Gestell angeordnete Ausnehmungen eingesetzt werden.According to a further advantageous embodiment, the hollow axis with its shaped pieces can be inserted in a plane that is inclined, even perpendicular, to the passage plane of the workpieces, in a plane correspondingly arranged in the frame.

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 essentially depends on the accessibility of the hollow axes with their shaped pieces to the frames and on the position of the locking devices, which should be as free and quick as possible to access.

Auch bei der Ausbildung der Formstücke sind verschiedene Ausführungsformen möglich.Various embodiments are also possible in the formation of the shaped pieces.

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 shaped pieces are cuboid or cube-shaped at the two ends of the hollow axis and the corresponding recesses in the frame. In order to ensure a desired, always radially oriented position of the lubricant outlet openings, it proves to be particularly advantageous to design the shaped pieces at the two ends of the hollow axis and the corresponding recesses in the frame so differently that only ever the one you want Use with an appropriately aligned position of the lubricant outlet openings is guaranteed and otherwise it is not possible to insert the shaped pieces into the recesses at all.

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 proves to be particularly advantageous to design the shaped pieces and the corresponding recesses in the frame in a semicircular manner at one end and to provide them with continuously adjoining, mutually parallel, flat surfaces which also run at different distances from one another, for example on the left side of the hollow roller with a larger and on the right side of the hollow roller with a smaller distance. As a result, there is only one possibility of inserting the shaped pieces into the recesses and thus always the desired circumferential orientation of the greasing agent 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 further development of the invention, the locking device consists of screws with external or internal hexagon head or slotted head which penetrate through holes in the frame and which engage with their external thread in a corresponding internal thread of the bore and lock the fitting by clamping on at least one surface. Several screws can also be used to lock each fitting.

Nach einer ersten Ausführungsform einer solchen Arretierungseinrichtung bestehen die Schrauben aus Hohlschrauben mit einer unter der Vorspannung einer Feder stehenden Kugel, die in der Arretierungslage in eine im Formstück vorgesehene Kalotte eingreift. Dabei ist vorteilhaft die Vorspannung der Feder so groß bemessen, daß ein selbsttätiges Lösen der Hohlschrauben unter dem Einfluß sämtlicher denkbaren äußeren Kräfte, auch von Schwingungskräften, ausgeschlossen ist.According to a first embodiment of such a locking device, the screws consist of hollow screws with a pretensioned spring standing ball which engages in the locking position in a calotte provided in the fitting. The bias of the spring is advantageously dimensioned so large that automatic loosening of the banjo bolts under the influence of all conceivable external forces, including vibrational forces, is excluded.

Nach einer zweiten Ausführungsform der Arretierungseinrichtung sind die Schrauben an ihrem Kopf mit Federringen gegen unbeabsichtigte Drehungen gesichert und an ihrem freien Ende mit einem Schneidring oder einem Zentrierkegel versehen sind, die in der Arretierungslage in eine im Formstück vorgesehene kreisring- oder kegelförmige Ausnehmung eingreifen.According to a second embodiment of the locking device, the screws are secured on their head with spring washers against unintentional rotation and are provided at their free end with a cutting ring or a centering cone which engage in the locking position in an annular or conical recess provided in the fitting.

Platine) parallel verlaufenden Einschubebene 29, 30 (s. strichpunktierte Linien in Fig. 2) in die entsprechenden Ausnehmungen 25, 26 einsetzbar. Es ist jedoch auch möglich, die Hohlachsen 15, 16 entgegengesetzt der Förderrichtung gemäß dem Pfeil 28 in entsprechende Ausnehmungen 25, 26 einzusetzen.As can be seen in particular from FIG. 3, according to the invention each hollow axis 15, 16 is provided at both ends with a shaped piece 23, 24 which can be inserted in a form-fitting manner in a correspondingly configured recess 25, 26 in the lower and in the upper frame 13, 14 and by means of it one generally designated 27 Locking device is releasably supported. 3, the hollow axis 15 in the lower and also the hollow axis 16 in the upper frame 13, 14 are opposite to the conveying direction according to the arrow 28 in an insertion plane 29, 30 running parallel to the through plane 21 of the workpiece (not the board) (not shown) (see dash-dotted lines in Fig. 2) in the corresponding recesses 25, 26 can be used. However, it is also possible to insert the hollow axes 15, 16 in opposite recesses to the conveying direction according to the arrow 28 in corresponding recesses 25, 26.

Und schließlich ist es erfindungsgemäß möglich, auch die Hohlachsen 15, 16 mit ihren Formstücken 23, 24 in einer zur Durchlaufebene der nicht dargestellten Werkstücke schräg verlaufenden, auch senkrechten Ebene, beispielsweise in Richtung des Doppelpfeiles 22 von Fig. 3 in entsprechend im unteren und oberen Gestell 13, 14 angeordnete Ausnehmungen 25, 16 einzusetzen.And finally, according to the invention, it is also possible for the hollow axes 15, 16 with their shaped pieces 23, 24 in a plane that is also inclined to the through plane of the workpieces, not shown, also perpendicular, for example in the direction of the double arrow 22 from FIG. 3 in the lower and upper To use frame 13, 14 arranged recesses 25, 16.

Gemäß den Fig. 3 und 4 sind die Formstücke 23, 24 im unteren und oberen Gestell 13, 14 quaderförmig ausgebildet. Sie können jedoch auch eine Würfelform aufweisen. Ferner ist es möglich, die Formstücke 23, 24 und die entsprechenden Ausnehmungen 25, 26 im unteren und oberen Gestell 13, 14 an einem Ende halbkreisförmig auszubilden und mit daran kontinuierlich anschließenden, zueinander parallelen, ebenen Flächen zu versehen. Eine solche Ausbildung ist in Fig. 3 in der linken Hälfte strichpunktiert angedeutet.3 and 4, the fittings 23, 24 in the lower and upper frame 13, 14 are cuboid. However, they can also have a cube shape. Furthermore, it is possible to form the shaped pieces 23, 24 and the corresponding recesses 25, 26 in the lower and upper frames 13, 14 at one end in a semicircular shape and to provide them with continuously adjoining, mutually parallel, flat surfaces. Such a design is indicated by dash-dotted lines in FIG. 3 in the left half.

Wie aus Fig. 4 entnommen werden kann, besteht die Arretierungsvorrichtung 27 von Fig. 3 aus zwei durch das untere Gestell 13 hindurchgreifenden Schrauben 31, 32, die mit einem Außen- oder Innensechskantkopf oder auch mit einem Schlitzkopf versehen sein können. Mit ihrem Außengewinde 33 greifen die beiden Schrauben 31, 32 in ein entsprechendes Innengewinde 34 der Bohrungen 35 im unteren und oberen Gestell 13, 14 ein und klemmen das Formstück 23 an seiner unteren Fläche 38. Im dargestellten Fall bestehen die Schrauben 31, 32 aus Hohlschrauben mit einer unter der Vorspannung einer nicht dargestellten Feder stehenden Kugel 36, die in der Arretierungslage in eine im Formstück 23 vorgesehene Kalotte 37 eingreift. Dabei ist vorteilhaft die Vorspannung der Feder so groß bemessen, daß ein selbsttätiges Lösen der Hohlschrauben 31, 32 unter dem Einfluß sämtlicher denkbaren äußeren Kräfte, auch von Schwingungskräften, ausgeschlossen bleibt.As can be seen from FIG. 4, the locking device 27 of FIG. 3 consists of two screws 31, 32 which pass through the lower frame 13 and which can be provided with an external or internal hexagon head or also with a slotted head. With their external thread 33, the two screws 31, 32 engage in a corresponding internal thread 34 of the bores 35 in the lower and upper frame 13, 14 and clamp the shaped piece 23 on its lower surface 38. In the illustrated case, the screws 31, 32 consist of hollow screws with a ball 36 under the pretension of a spring, not shown, which engages in the locking position in a dome 37 provided in the shaped piece 23. The bias of the spring is advantageously dimensioned so large that automatic loosening of the hollow screws 31, 32 under the influence of all conceivable external forces, including vibrational forces, is excluded.

Die Erfindung läßt es auch zu, die Schrauben 31, 32 als Vollschrauben auszubilden, an ihrem Kopf mit Federringen gegen unbeabsichtigte Drehungen abzusichern und an ihrem freien Ende mit einem Schneidring oder einem Zentrierkegel zu versehen, die in der Arretierungslage in eine im Formstück 23, 24 vorgesehene kreisring- oder kegelförmige Ausnehmung, ähnlich den Kalotten 37, eingreifen.The invention also allows the screws 31, 32 to be designed as full screws, secured at their heads with spring washers against unintentional rotation and provided at their free end with a cutting ring or a centering cone which, in the locking position, fits into a fitting 23, 24 The provided circular or conical recess, similar to the calottes 37, engage.

Um eine eindeutige Zuordnung der Befettungsmittel-Austrittsöffnungen 18 und damit auch der Hohlachsen 15, 16 im unteren und im oberen Gestell 13, 14 bei einer Auswechslung 16 im unteren und im oberen Gestell 13, 14 sicherzustellen, ist es vorteilhaft, beispielsweise die linken Formstücke 23 geringfügig anders als die Formstücke 24 an der rechten Bildseite der Fig. 3 auszubilden. Dadurch können die Hohlachsen 15, 16 mit ihren Befettungswalzen 11, 12 auch von fachlich ungeschulten Personen nur in einer einzigen Einbaulage und damit korrekt in die entsprechenden Ausnehmungen 25, 26 eingesetzt werden. In diesem Fall sind selbstverständlich die Hohlachsen 15, 16 drehfest mit den Formstücken 23, 24 verbunden.For a clear assignment of the greasing agent outlet openings 18 and thus also the hollow axes 15, 16 in the lower and in the upper frame 13, 14 in the case of a replacement 16 in the lower and in the upper frame 13, 14 To ensure, it is advantageous, for example, to design the left shaped pieces 23 slightly differently than the shaped pieces 24 on the right-hand side of FIG. 3. As a result, the hollow axles 15, 16 with their greasing rollers 11, 12 can also be used by technically untrained persons only in a single installation position and thus correctly in the corresponding recesses 25, 26. In this case, of course, the hollow axes 15, 16 are connected in a rotationally fixed manner to the shaped pieces 23, 24.
