For adaption to use different cutting-circle diameters (9) of the tools (6), the pressure-applying elements (4, 5) can be adjusted in a direction (22, 23) lying obliquely with respect to the transporting direction (11) of the workpieces. In order to be able to set the pressure-applying elements (4, 5) in relation to the profile depth (8) of the profile cutters of the tool (6), too, the pressure-applying elements (4, 5) can be adjusted in a direction (23, 34) lying with opposite obliquity with respect to the transporting direction (11). The position of the adjusting directions (22, 33, 23, 34) is chosen so that the pressure-applying elements (4, 5), upon adjustment, arrive at an optimal position in dependence on the cutting-circle diameter (9) and the profile depth (8) of the respective tool (6). <IMAGE>

Description

Die Erfindung betrifft eine Andrückvorrichtung für Maschinen zum Bearbeiten von Werkstücken aus Holz, Kunststoff und dergleichen nach dem Oberbegriff des Anspruches 1.The invention relates to a pressing device for machines for machining workpieces made of wood, plastic and the like according to the preamble of claim 1.

Diese bekannte Andrückvorrichtung hat in Transportrichtung der zu bearbeitenden Werkstücke vor und hinter der Spindel bzw. dem auf ihr sitzenden Werkzeug jeweils ein Andrückelement, das auf dem Werkstück aufliegt und während der Bearbeitung durch das Werkzeug unzulässige Bewegungen des Werkstückes verhindert. Damit das Werkstück während der Bearbeitung optimal abgestützt wird, müssen die Andrückelemente nahe dem Werkzeug angeordnet sein. Die Einstellung der Andrückelemente ist aufwendig und schwierig. Bei einem Wechsel des Werkzeuges mit einem anderen Flugkreisdurchmesser müssen die Andrückelemente entsprechend neu eingestellt werden. Die Andrückelemente werden hierbei einzeln nach Augenmaß eingestellt, wobei nicht nur der Flugkreisdurchmesser der Messer des Werkzeuges, sondern auch die profiltiefe der Messer berücksichtigt werden muß.This known pressing device has in the transport direction of the workpieces to be machined in front of and behind the spindle or the tool sitting on it, a pressing element which rests on the workpiece and prevents inadmissible movements of the workpiece during the machining by the tool. So that the workpiece is optimally supported during machining, the pressure elements must be arranged close to the tool. The setting of the pressure elements is complex and difficult. When changing the tool with a different flight circle diameter, the pressure elements must be reset accordingly. The pressure elements are set individually by eye, whereby not only the flight circle diameter of the knife of the tool, but also the profile depth of the knife must be taken into account.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Andrückvorrichtung so auszubilden, daß die Andrückelemente einfach und schnell in die jeweilige Lage eingestellt werden können.The invention has for its object to design the generic pressing device so that the pressing elements can be easily and quickly set in the respective position.

Diese Aufgabe wird bei der gattungsgemäßen Andrückvorrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved with the generic pressing device according to the invention with the characterizing features of claim 1.

Bei der erfindungsgemäßen Andrückvorrichtung werden die Andrückelemente in den verschiedenen schrägen Richtungen verstellt, um sie sowohl in bezug auf den Flugkreisdurchmesser des Werkzeuges als auch in bezug auf die Profiltiefe der Profilmesser des Werkzeuges einzustellen. Die Lage der Verstellrichtungen ist so gewählt, daß die Andrückelemente in Abhängigkeit vom Flugkreisdurchmesser und der Profiltiefe des jeweiligen Werkzeuges bei der Verstellung in eine optimale Lage gelangen. Darum kann die Verstellung der Andrückelemente auch von weniger geübten Personen einfach, schnell und genau durchgeführt werden. Diese Verstellungen der Andrückelemente können bevorzugt in linearer Richtung erfolgen. Ebenso ist es aber auch möglich, die Andrückelemente durch eine entsprechende Schwenkbewegung in der jeweiligen Richtung, also auf einer gekrümmten Bahn, in die erforderliche Lage zu bringen.In the pressing device according to the invention, the pressing elements are adjusted in the different oblique directions in order to adjust them both with respect to the tool's circle diameter as well as with respect to the profile depth of the profile knife of the tool. The position of the adjustment directions is selected so that the pressure elements, depending on the flight circle diameter and the profile depth of the respective tool, reach an optimal position during the adjustment. Therefore, the adjustment of the pressure elements can be carried out easily, quickly and precisely even by less experienced people. These adjustments of the pressing elements can preferably be carried out in the linear direction. However, it is also possible to bring the pressing elements into the required position by means of a corresponding pivoting movement in the respective direction, that is to say on a curved path.

Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und der Zeichnung.Further features of the invention result from the further claims, the description and the drawing.

Die Erfindung wird anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Die Zeichnung zeigt in Ansicht und in schematischer Darstellung eine erfindungsgemäße Andrückvorrichtung.The invention is explained in more detail using an exemplary embodiment shown in the drawing. The drawing shows a view and a schematic representation of a pressing device according to the invention.

Die Andrückvorrichtung wird bei Bearbeitungsmaschinen für Holz, Kunststoff und dergleichen eingesetzt und dient dazu, vor und hinter einem rotierenden Werkzeug angeordnete Andrückelemente in Abhängigkeit vom Werkzeugdurchmesser und der Profiltiefe der Profilmesser des Werkzeuges einzustellen.The pressing device is used in processing machines for wood, plastic and the like and is used to adjust pressing elements arranged in front of and behind a rotating tool depending on the tool diameter and the profile depth of the profile knife of the tool.

Die Andrückvorrichtung hat einen ortsfest angeordneten Träger 1, auf dem zwei Einstellgeräte 2 und 3 angeordnet sind. Mit dem Einstellgerät 2 werden die Andrückelemente 4 und 5 in bezug auf die Profiltiefe und mit dem Einstellgerät 3 in bezug auf den Werkzeugdurchmesser eingestellt. Das Werkzeug 6 sitzt drehfest auf einer im Ausführungsbeispiel horizontalen Spindel 7 der Bearbeitungsmaschine. Das Werkzeug 6 ist ein Messerkopf, an dessen Umfang verteilt angeordnete Profilmesser in bekannter Weise befestigt sind. In der Zeichnung ist die Profiltiefe der (nicht dargestellten) Profilmesser mit 8 bezeichnet. Das Werkzeug 6 hat einen Flugkreisdurchmesser 9, der dem Werkzeugdurchmesser entspricht. Durch die größte Profiltiefe 8 der Profilmesser des Werkzeuges 6 wird der Grundkreisdurchmesser 10 des Werkzeuges bestimmt.The pressing device has a fixed support 1 on which two setting devices 2 and 3 are arranged. With the setting device 2, the pressing elements 4 and 5 are set in relation to the profile depth and with the setting device 3 in relation to the tool diameter. The tool 6 sits in a rotationally fixed manner on a spindle 7 of the processing machine which is horizontal in the exemplary embodiment. The tool 6 is a knife head, on the circumference of which distributed profile knives are fastened in a known manner. In the drawing, the profile depth of the (not shown) profile knife is designated 8. The tool 6 has a flight circle diameter 9 which corresponds to the tool diameter. The base circle diameter 10 of the tool is determined by the greatest profile depth 8 of the profile knife of the tool 6.

Mit den Profilmessern des Werkzeuges 6 wird ein unter dem Werkzeug gefördertes (nicht dargestelltes) Werkstück bearbeitet bzw. profiliert. Um eine optimale Bearbeitung des Werkstückes zu gewährleisten, sind in Transportrichtung 11 des Werkstückes vor und hinter dem Werkzeug 6 die Andrückelemente 4 und 5 vorgesehen. Sie sollen, um eine optimale Andrückwirkung zu erzielen, mit möglichst geringem Abstand zum Werkzeug 6 vorgesehen sein. Wird das auf der Spindel 7 sitzende Werkzeug 6 gegen ein Werkzeug mit einem anderen Flugkreisdurchmesser 9 und/oder einer anderen Profiltiefe 8 seiner Schneidmesser eingesetzt, müssen die Andrückelemente 4, 5 entsprechend eingestellt werden. Dies ist mit Hilfe der beiden Einstellgeräte 2 und 3 und der im folgenden beschriebenen Ausbildung der Andrückvorrichtung sehr einfach und schnell möglich. Die Andrückelemente 4, 5 lassen sich auch von ungeübten Arbeitskräften in einfacher Weise genau in die erforderliche Lage relativ zum jeweiligen Werkzeug 6 einstellen.With the profile knives of the tool 6, a workpiece (not shown) conveyed under the tool is machined or profiled. In order to ensure optimum machining of the workpiece, the workpiece is in front of and behind the tool 6 in the direction of transport 11 the pressing elements 4 and 5 are provided. In order to achieve an optimal pressing effect, they should be provided as close as possible to the tool 6. If the tool 6 seated on the spindle 7 is used against a tool with a different flight circle diameter 9 and / or a different profile depth 8 of its cutting knife, the pressing elements 4, 5 must be adjusted accordingly. This can be done very easily and quickly using the two setting devices 2 and 3 and the design of the pressing device described below. The pressing elements 4, 5 can also be adjusted by inexperienced workers in a simple manner precisely in the required position relative to the respective tool 6.

Die Einstellgeräte 2, 3 sind an sich bekannt und haben jeweils eine Positionsanzeige 12 und 13, in der der jeweilige Wert digital angezeigt wird. Jedes Einstellgerät 2, 3 ist mit einer Drehhülse 14 und 15 zur drehfesten Aufnahme jeweils einer (nicht dargestellten) Stellwelle versehen. Durch Drehen der jeweiligen Stellwelle werden die Andrückelemente 4, 5 in noch zu beschreibender Weise in der erforderlichen Richtung relativ zum orts- bzw. maschinenfesten Träger 1 verstellt. Gleichzeitig wird in der Positionsanzeige 12, 13 der jeweilige Wert angezeigt, da die Drehhülsen 14, 15 in bekannter Weise mit den Anzeigeelementen gekuppelt sind.The setting devices 2, 3 are known per se and each have a position indicator 12 and 13 in which the respective value is displayed digitally. Each setting device 2, 3 is provided with a rotating sleeve 14 and 15 for the rotationally fixed reception of one (not shown) adjusting shaft. By turning the respective adjusting shaft, the pressing elements 4, 5 are adjusted in the required direction relative to the stationary or machine-fixed carrier 1 in a manner to be described. At the same time, the respective value is displayed in the position display 12, 13, since the rotating sleeves 14, 15 are coupled to the display elements in a known manner.

Der Träger 1 ist vorzugsweise im wesentlichen plattenförmig ausgebildet, so daß er wenig Raum in Anspruch nimmt. Damit er möglichst nahe an das Werkzeug 6 heranreicht, ist er mit einer entsprechenden konkaven Vertiefung bzw. Ausnehmung 16 versehen, die an den Flugkreisdurchmesser 9 des größten, auf der Spindel 7 anzuordnenden Werkzeuges 6 angepaßt ist.The carrier 1 is preferably substantially plate-shaped, so that it takes up little space. In order for it to come as close as possible to the tool 6, it is provided with a corresponding concave recess or recess 16 that corresponds to the flight circle diameter 9 of the largest tool 6 to be arranged on the spindle 7 is adapted.

Der Träger 1 ist an einer Seite mit einer Führung 17 für einen Zwischenträger 18 versehen, der das Andrückelement 5 trägt. Der Zwischenträger 18 ist mit einer entsprechenden Gegenführung 19 versehen, die längs der Führung 17 des Trägers 1 verstellbar ist. Als Gegenführung 19 kann der Zwischenträger 18 beispielsweise mit einer im Querschnitt U-förmigen Vertiefung versehen sein, in die die Führung 17 des Trägers 1 eingreift. Die Vertiefung kann auch als Schwalbenschwanznut ausgebildet sein, an welche die Führung 17 entsprechend angepaßt ist.The carrier 1 is provided on one side with a guide 17 for an intermediate carrier 18 which carries the pressing element 5. The intermediate carrier 18 is provided with a corresponding counter-guide 19 which is adjustable along the guide 17 of the carrier 1. As a counter-guide 19, the intermediate carrier 18 can be provided, for example, with a recess with a U-shaped cross section, into which the guide 17 of the carrier 1 engages. The depression can also be designed as a dovetail groove, to which the guide 17 is adapted accordingly.

Der Träger 1 ist an einer Seite mit einer in der Zeichnung nur schematisch dargestellten Gewindespindel 20 versehen, auf der eine Spindelmutter 21 sitzt, die mit dem Zwischenträger 18 fest verbunden ist. Durch Drehen der Gewindespindel 20 kann somit der Zwischenträger 18 längs der Führung 17 des Trägers 1 stufenlos verstellt werden.The carrier 1 is provided on one side with a threaded spindle 20, shown only schematically in the drawing, on which a spindle nut 21 is seated, which is firmly connected to the intermediate carrier 18. By rotating the threaded spindle 20, the intermediate carrier 18 can thus be continuously adjusted along the guide 17 of the carrier 1.

Durch die Lage der Gewindespindel 20 und der Führung 17 ist die Verstellrichtung 22 des Zwischenträgers 18 und damit des Andrückelementes 5 bestimmt. In dieser Richtung 22 wird das Andrückelement 5 verstellt, wenn ein Werkzeug 6 mit einem anderen Flugkreisdurchmesser 9 eingesetzt wird. Das Andrückelement 5 kann zusätzlich relativ zum Zwischenträger 18 in Richtung des Doppelpfeiles 23 verstellt werden. Mit einer solchen Verstellmöglichkeit kann das Andrückelement 5 an die jeweilige Profiltiefe 8 der Profilmesser des jeweiligen Werkzeuges 6 angepaßt werden.

The pressing element 4 is provided on a lower side with a downwardly projecting guide bar 31 which engages in a corresponding groove 32 on the upper side of the slide part 30. The guide bar 31 and the groove 32 lie at an acute angle to the threaded spindle 20. The guide bar 31 and the threaded spindle 20 diverge in the direction of the tool 6. The position of the guide bar 31 determines the adjustment direction 33 in which the pressing element 4 is adapted can be adjusted to different tool diameters relative to the slide part 30 or to the carrier 1.

Um das Andrückelement 4 an die unterschiedlichen Profiltiefen 8 der Profilmesser des jeweiligen Werkzeuges 6 anzupassen, läßt sich das Schlittenteil 30 in Richtung 34 auf dem Träger 1 verstellen.In order to adapt the pressing element 4 to the different profile depths 8 of the profile knives of the respective tool 6, the slide part 30 can be adjusted in the direction 34 on the carrier 1.

Das Schlittenteil 29 ist mit einer Gewindespindel 35 in Verstellrichtung 33 verstellbar. Auf der Gewindespindel 35 sitzt eine (nicht dargestellte) Spindelmutter, die fest mit dem Schlittenteil 29 verbunden ist. Die Gewindespindeln 29 und 35 sind mit der in der Drehhülse 15 des Einstellgerätes 3 aufgenommenen Stellwelle gekuppelt, so daß durch Drehen der Stellwelle die beiden Gewindespindeln 20, 35 gemeinsam gedreht werden. Dadurch werden das Schlittenteil 29 und der Zwischenträger 18 gegensinnig synchron in den Verstellrichtungen 22, 33 verstellt.The slide part 29 is adjustable in the adjustment direction 33 with a threaded spindle 35. A spindle nut (not shown) sits on the threaded spindle 35 and is fixedly connected to the slide part 29. The threaded spindles 29 and 35 are coupled to the adjusting shaft accommodated in the rotating sleeve 15 of the setting device 3, so that the two threaded spindles 20, 35 are rotated together by rotating the adjusting shaft. As a result, the slide part 29 and the intermediate carrier 18 are adjusted in opposite directions synchronously in the adjustment directions 22, 33.

Auch das Schlittenteil 30 wird mittels einer Gewindespindel 36 in Verstellrichtung 34 verstellt. Das Schlittenteil 30 ist mit einer (nicht dargestellten) Spindelmutter versehen, die auf der Gewindespindel 36 sitzt. Sie ist zusammen mit der Gewindespindel 24 mit der in der Drehhülse 14 des Einstellgerätes 2 drehfest aufgenommenen Stellwelle gekuppelt. Wird sie gedreht, dann werden die beiden Gewindespindeln 24, 36 so gedreht, daß das Andrückelement 5 und das Schlittenteil 30 gegensinnig synchron in den Verstellrichtungen 23, 34 verstellt werden.The slide part 30 is also adjusted in the adjustment direction 34 by means of a threaded spindle 36. The slide part 30 is provided with a spindle nut (not shown) which sits on the threaded spindle 36. It is coupled together with the threaded spindle 24 to the actuating shaft, which is received in a rotationally fixed manner in the rotating sleeve 14 of the setting device 2. If it is rotated, then the two threaded spindles 24, 36 are rotated so that the pressing element 5 and the slide part 30 are adjusted in opposite directions synchronously in the adjustment directions 23, 34.

Die beiden Verstellrichtungen 33 und 34 liegen unter einem spitzen Winkel zueinander.The two adjustment directions 33 and 34 are at an acute angle to one another.

Das Schlittenteil 29 und der Zwischenträger 18 werden gleichzeitig und synchron verstellt, so daß beide Andrückelemente 4, 5 gleichzeitig in den Verstellrichtungen 22 und 33 zur Anpassung an unterschiedliche Flugkreisdurchmesser 9 der Werkzeuge 6 bewegt werden können. Die Spindeltriebe 20, 21; 35 sind in der beschriebenen Weise miteinander gekoppelt und mit dem Einstellgerät 3 so verbunden, daß in der Positionsanzeige 13 der jeweilige Wert des Werkzeugdurchmessers digital angezeigt wird. Durch Drehen der in der Drehhülse 15 aufgenommenen Stellwelle wird der jeweilige Werkzeugdurchmesser (Flugkreisdurchmesser 9) in der Positionsanzeige eingestellt. Gleichzeitig werden über die Spindeltriebe 20, 21; 35 das Schlittenteil 29 in Verstellrichtung 33 und der Zwischenträger 18 mit dem Andrückelement 5 in Verstellrichtung 22 verschoben.The slide part 29 and the intermediate carrier 18 are adjusted simultaneously and synchronously, so that both pressing elements 4, 5 can be moved simultaneously in the adjustment directions 22 and 33 to adapt to different flight circle diameters 9 of the tools 6. The spindle drives 20, 21; 35 are coupled to each other in the manner described and connected to the setting device 3 so that the respective value of the tool diameter is digitally displayed in the position indicator 13. By turning the adjusting shaft accommodated in the rotating sleeve 15, the respective tool diameter (flight circle diameter 9) is set in the position display. At the same time, the spindle drives 20, 21; 35 the slide part 29 is displaced in the adjustment direction 33 and the intermediate carrier 18 with the pressing element 5 in the adjustment direction 22.

Mit den beiden Spindeltrieben 24, 25; 36 werden das Schlittenteil 30 und das Andrückelement 5 in der beschriebenen Weise verstellt. In der Positionsanzeige 12 des Einstellgerätes 2 wird beim Einstellen der jeweiligen Profiltiefe 8 der Profilmesser des jeweils verwendeten Werkzeuges 6 der jeweilige Wert unmittelbar angezeigt. Die Andrückelemente 4, 5 lassen sich darum sehr einfach und dennoch hochgenau in gewünschtem Maße verstellen. Die Koppelung der Spindeltriebe 24, 25 und 36 bzw. 20, 21 und 35 kann mechanisch durch Getriebe, aber auch elektronisch erfolgen. Da die Drehhülsen 14, 15 mit den Anzeigeelementen der Positionsanzeigen 12, 13 gekoppelt sind, wird der entsprechende Wert für die Profiltiefe 8 der Profilmesser bzw. für den Flugkreisdurchmesser 9 des Werkzeuges 6 unmittelbar angezeigt, so daß sich die Andrückelemente 4, 5 mühelos in die erforderliche Lage zum Werkzeug 6 verstellen lassen.With the two spindle drives 24, 25; 36, the slide part 30 and the pressing element 5 in the described Way adjusted. In the position display 12 of the setting device 2, the respective value is displayed directly when the respective profile depth 8 of the profile knife of the tool 6 used is set. The pressing elements 4, 5 can therefore be adjusted very simply and yet with high precision to the desired extent. The coupling of the spindle drives 24, 25 and 36 or 20, 21 and 35 can be done mechanically by gears, but also electronically. Since the rotating sleeves 14, 15 are coupled to the display elements of the position indicators 12, 13, the corresponding value for the profile depth 8 of the profile knife or for the flight circle diameter 9 of the tool 6 is displayed directly, so that the pressing elements 4, 5 effortlessly into the Have the required position for tool 6 adjusted.

Die Verstellrichtungen 22, 23, 33, 34 haben, projiziert auf die Zeichenebene, die Form eines W. Die Andrückelemente 4, 5 werden zur Einstellung auf unterschiedliche Werkzeugdurchmesser in den Verstellrichtungen 22 und 33 verstellt. In den Richtungen 23 und 34 werden die Andrückelemente 4, 5 verstellt, um sie an die jeweilige Profiltiefe 8 der im Werkzeug 6 eingesetzten Profilmesser anzupassen. Diese Verstellrichtungen sind so gewählt, daß die Andrückelemente 4, 5 den optimalen Abstand in Transportrichtung 11 vor und hinter dem jeweiligen Werkzeug 6 haben, so daß die mit dem Werkzeug 6 zu bearbeitenden Werkstücke während des Bearbeitungsvorganges optimal abgestützt werden. Nach einem Werkzeugwechsel werden die Andrückelemente 4, 5 zunächst zur Anpassung an den jeweiligen Werkzeugdurchmesser längs der Verstellrichtungen 22, 33 mit Hilfe des Einstellgerätes 3 eingestellt. Anschließend wird mit dem Einstellgerät 2 die Lage der Andrückelemente 4 und 5 an die jeweilige Profiltiefe 8 angepaßt, wobei die Andrückelemente in den Verstellrichtungen 23, 34 verstellt werden. Mit den beiden Einstellungen ist es somit in einfacher Weise möglich, die Andrückelemente 4, 5 in die jeweils günstigste Lage zu verstellen. An den Positionsanzeigen 12, 13 der Einstellgeräte 2, 3 läßt sich der einzustellende Wert sehr einfach einstellen und ablesen.The adjustment directions 22, 23, 33, 34, projected onto the drawing plane, have the shape of a W. The pressure elements 4, 5 are adjusted in the adjustment directions 22 and 33 for adjustment to different tool diameters. The pressing elements 4, 5 are adjusted in the directions 23 and 34 in order to adapt them to the respective profile depth 8 of the profile knife used in the tool 6. These adjustment directions are selected so that the pressing elements 4, 5 have the optimum distance in the transport direction 11 in front of and behind the respective tool 6, so that the workpieces to be machined with the tool 6 are optimally supported during the machining process. After a tool change, the pressing elements 4, 5 are first adjusted to the respective tool diameter along the adjustment directions 22, 33 with the aid of the setting device 3. The position of the pressing elements 4 and 5 is then adjusted to the respective one using the setting device 2 Profile depth 8 adapted, the pressing elements are adjusted in the adjustment directions 23, 34. With the two settings, it is thus possible in a simple manner to adjust the pressing elements 4, 5 to the most favorable position in each case. The value to be set can be set and read very easily on the position displays 12, 13 of the setting devices 2, 3.

Die verschiedenen Verstellrichtungen 22, 23, 33, 34 liegen jeweils unter spitzen Winkeln zueinander. In der Zeichnung sind für die Andrückelemente 4, 5 jeweils zwei verschiedene Stellungen eingezeichnet, die zu entsprechend unterschiedlichen Werkzeugdurchmessern gehören. Wird die Profiltiefe 8 der Profilmesser des Werkzeuges bei der Einstellung berücksichtigt, dann werden die Andrückelemente 4, 5 in der beschriebenen Weise anschließend in Verstellrichtung 23, 34 verstellt.The various adjustment directions 22, 23, 33, 34 are each at acute angles to one another. In the drawing, two different positions are drawn for the pressing elements 4, 5, which belong to correspondingly different tool diameters. If the profile depth 8 of the profile knife of the tool is taken into account in the setting, then the pressing elements 4, 5 are then adjusted in the manner described in the adjustment direction 23, 34.

Die Verstellrichtungen 22, 23, 33, 34 sind dadurch bestimmt worden, daß zunächst anhand der verschiedenen Werkzeuge die jeweils optimale Position der Andrückelemente 4, 5 bestimmt worden ist. Durch die entstehenden Meßpunkte sind dann die Verstellrichtung 23 bzw. 34 und 22 bzw. 33 bestimmende Geraden gelegt worden, die den Meßpunkten am besten angenähert sind. Dadurch ist gewährleistet, daß die Andrückelemente 4, 5 nach der erforderlichen Einstellung in bezug auf das jeweils eingesetzte Werkzeug 6 eine optimale oder zumindest angenähert optimale Lage einnehmen.The adjustment directions 22, 23, 33, 34 have been determined by first determining the optimal position of the pressing elements 4, 5 using the various tools. The adjustment points 23 or 34 and 22 or 33 defining the straight lines which best approximate the measurement points are then laid through the measurement points which are created. This ensures that the pressure elements 4, 5 assume an optimal or at least approximately optimal position after the required adjustment in relation to the tool 6 used in each case.

Die Andrückelemente 4, 5 sind im übrigen in bekannter Weise ausgebildet.The pressure elements 4, 5 are otherwise formed in a known manner.

Die Andrückvorrichtung ist konstruktiv einfach ausgebildet und kann auch von ungeübten Kräften ohne weiteres bedient werden. Mit den Einstellgeräten 2, 3 wird der jeweilige Wert des Flugkreisdurchmessers und der Profiltiefe eingestellt. Über die Stellantriebe werden die Andrückelemente 4, 5 in die entsprechenden Positionen verschoben.The pressing device is of simple construction and can also be operated easily by inexperienced forces. The respective value of the flight circle diameter and the profile depth is set with the setting devices 2, 3. The pressure elements 4, 5 are moved into the corresponding positions via the actuators.

Die erforderlichen Werte für die Profilteile 8 und den Flugkreisdurchmesser 9 können auch über eine CNC-Steuerung der Maschine vorgegeben werden. Die Spindeln 20, 24, 35, 36 werden dann motorisch angetrieben und die Andrückelemente 4, 5 so verschoben, bis die durch die CNC-Steuerung vorgegebenen Werte erreicht sind.The required values for the profile parts 8 and the flight circle diameter 9 can also be specified via a CNC control of the machine. The spindles 20, 24, 35, 36 are then driven by a motor and the pressing elements 4, 5 are shifted until the values specified by the CNC control have been reached.

Beim dargestellten Ausführungsbeispiel können die drehfest mit den Drehhülsen 14, 15 der Einstellgeräte 2, 3 verbundenen Stellwellen von Hand mittels Kurbeln oder motorisch gedreht werden.In the illustrated embodiment, the actuating shafts connected to the rotating sleeves 14, 15 of the setting devices 2, 3 in a rotationally fixed manner can be rotated manually by means of cranks or by motor.

Auch ist es möglich, jedes Andrückelement 4, 5 für sich in der jeweiligen Richtungen 22, 23, 33, 34 zu verstellen. Für diesen Fall sind vier Einstellgeräte vorgesehen, deren Drehhülsen mit den entsprechenden Spindeln antriebsverbunden sind. Die Verstellung kann wiederum von Hand oder motorisch durchgeführt werden.It is also possible to adjust each pressing element 4, 5 individually in the respective directions 22, 23, 33, 34. In this case, four setting devices are provided, the sleeves of which are drive-connected to the corresponding spindles. The adjustment can in turn be carried out by hand or by motor.

Mit der Vorrichtung ist es möglich, die Andrücke in der Maschine entsprechend den gemessenen Flugkreisdurchmessern und Profiltiefen der Werkzeuge mit Hilfe der Einstellgeräte einfach und genau einzustellen, noch bevor die Werkzeuge auf den Spindeln montiert werden. Dies hat eine Rüstzeitsparnis und die Vermeidung von Einstellfehlern zur Folge.With the device, it is possible to set the pressures in the machine simply and precisely in accordance with the measured flight circle diameters and profile depths of the tools with the aid of the setting devices, even before the tools are mounted on the spindles. This saves set-up time and avoids setting errors.
