Description

Die Erfindung bezieht sich auf eine Richtbank zam Ausrichten von länglichen Gegenständen, wobei Mittel zur oszillierenden Auslenkung wenigstens eines Teilabschnitts der Gegenstände aus der Längsachse vorgesehen sind.The invention relates to a straightening bench for aligning elongated objects, wherein means for oscillating deflection of at least a portion of the objects from the longitudinal axis are provided.

Derartige Richtbänke ermöglichen das Geradebiegen von z.B. stangen- oder rohrförmigen Gegenständen. Es ist eine solche Einrichtung bekannt (US Patent 3.328.995), bei der der Gegenstand in einer Reihe von hintereinander angeordneten und gegeneinander verschiebbaren Backen eingespannt wird. Durch senkrecht zur Längsachse erfolgende vibrierende Relativbewegungen benachbarter Backen werden Teilabschnitte des auszurichtenden Gegenstandes ausgelenkt. Unterschiedliche Auslenkungsamplituden werden durch Variation der effektiven Hebelarme des antreibenden Hebelsystems erzielt.Such straightening benches enable the straight bending of e.g. rod-shaped or tubular objects. Such a device is known (US Pat. No. 3,328,995), in which the object is clamped in a row of jaws arranged one behind the other and displaceable relative to one another. Partial sections of the object to be aligned are deflected by vibrating relative movements of adjacent jaws perpendicular to the longitudinal axis. Different amplitudes of deflection are achieved by varying the effective lever arms of the driving lever system.

Diese bekannte Richtbank ist geeignet für die Ausrichtung von länglichen Gegenständen mit im wesentlichen gleichbleibendem Querschnittsprofil, während bei in Längsrichtung variablen Profilen aufwendige Anpassungen erforderlich werden. Zudem ist die Anordnung ungeeignet für Ausrichtungsverfahren, bei denen der an einem Ende fest eingespannte Gegenstand am freien Ende auszulenken ist.This known straightening bench is suitable for the alignment of elongated objects with a substantially constant cross-sectional profile, while in the case of profiles which are variable in the longitudinal direction, complex adjustments are required. In addition, the arrangement is unsuitable for alignment methods in which the object firmly clamped at one end is to be deflected at the free end.

Die vorliegende Erfindung bietet eine den Erfordernissen angepasste, vereinfachte Ausführung einer Richtbank, die gekennzeichnet ist durch eine um eine Mittellage verschiebbare Halterung, einen Hebel, der durch Antriebsmittel um einen festen Punkt hin- und hergeschwenkt werden kann, ein mit der Halterung in einem Drehpunkt verbundenes Verbindungsglied, das durch Einstellmittel um diesen Drehpunkt ausgelenkt werden kann und mit dem Hebel über eine Mitnehmeranordnung mit variablem Kopplungspunkt verbunden ist, das Ganze derart, dass in der Ruhelage der Einstellmittel der Kopplungspunkt mit dem festen Punkt zusammenfällt, so dass die Halterung beim Hin- & Herbewegen des Hebels in ihrer Mittellage verbleibt, während bei durch die Einstellmittel erfolgter Auslenkung des Verbindungsgliedes der Kopplungspunkt auf dem l'ebel vom festen Punkt verschoben und die Bewegung des Hebels auf die Halterung übertragen wird.The present invention offers a simplified embodiment of a straightening bench which is adapted to the requirements and is known is characterized by a bracket which can be moved around a central position, a lever which can be pivoted back and forth by drive means around a fixed point, a connecting element which is connected to the holder at a pivot point and which can be deflected by adjusting means about this pivot point and with the lever The whole is connected via a driver arrangement with a variable coupling point in such a way that in the rest position of the adjusting means the coupling point coincides with the fixed point, so that the holder remains in its central position when the lever is moved back and forth, while the adjusting means deflects it of the connecting link, the coupling point on the lever is moved from the fixed point and the movement of the lever is transmitted to the holder.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass Gegenstände mit über die Länge ungleichem Querschnitt, wie beispielsweise die Druckhämmer eines Aufschlagdruckers, ausgerichtet werden können und dass der zu treibende maschinelle Aufwand den tatsächlichen Anforderungen angepasst ist. Ferner gestattet es die Erfindung mit einfachen Mitteln, sowohl eine bequeme Aenderung des Maximums der um einen festen Referenzpunkt erfolgenden Auslenkung auszuführen, als auch eine gleichmässige Reduktion der Auslenkungsamplitude vom Maximum auf Null zu erzielen.The advantages achieved by the invention are essentially to be seen in the fact that objects with a cross-section that is unequal over the length, such as, for example, the print hammers of an impact printer, can be aligned and that the mechanical effort to be driven is adapted to the actual requirements. Furthermore, the invention makes it possible with simple means both to carry out a comfortable change in the maximum of the deflection taking place around a fixed reference point and also to achieve a uniform reduction of the deflection amplitude from the maximum to zero.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert.The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment.

Es zeigen:

  • Fig. 1 eine schematische Darstellung der erfindungsgemässen Vorrichtung, und
  • Fig. 2 eine perspektivische Ansicht eines Teils der in Fig. 1 gezeigten Vorrichtung im demontierten Zustand.
Show it:
  • Fig. 1 is a schematic representation of the device according to the invention, and
  • Fig. 2 is a perspective view of part of the device shown in Fig. 1 in the disassembled state.

Mit Hilfe der Fig. 1 werden im folgenden die Erfindung sowie ein Anwendungsbeispiel näher beschrieben. Dargestellt ist eine Richtbank zum Ausrichten individueller Druckhämmer von Aufschlagdruckern. Auf die Frage nach der Notwendigkeit des Ausrichtens solcher Hämmer wird hier nicht näher eingegangen. Es genügt die Feststellung, dass es bei solchen Hämmern darauf ankommt, dass gewisse Oberflächen parallel zueinander liegen und bestimmte Abstände aufweisen, um ein einwandfreies Arbeiten des Druckers zu gewährleisten.1, the invention and an application example are described in more detail below. A straightening bench for aligning individual print hammers of impact printers is shown. The question of the need to align such hammers is not dealt with here. Suffice it to say that with such hammers it is important that certain surfaces are parallel to one another and have certain distances between them to ensure that the printer works properly.

In Fig. 1 ist ein Hammer 1 gezeigt, dessen eir-, Ende in einer Einspannvorrichtung 2 und dessen anderes Ende in einer auf einem Führungsschlitten angeordneten Halterung 3 befestigt ist, die beispielsweise aus justierbaren Klemmbacken besteht. Die Einspannung kann, wie gezeigt, mit Hilfe einer Druckluftzylinderanordnung 4 oder anderer geeigneter Mittel erfolgen.In Fig. 1, a hammer 1 is shown, the end of which is fastened in a clamping device 2 and the other end of which is fastened in a holder 3 arranged on a guide carriage, which consists, for example, of adjustable clamping jaws. As shown, the clamping can take place with the aid of a compressed air cylinder arrangement 4 or other suitable means.

Der Schlitten ist auf einem Teil des allgemeinen Maschinenrahmens 5 derart montiert, dass er eine oszillierende Bewegung oder Schwingung um eine durch die Linie A-A gekennzeichnete Ausgangslage ausführen kann. Dies bedeutet, dass auch das in der Halterung eingespannte Hammerende um diese Linie ausgelenkt wird.The carriage is mounted on a part of the general machine frame 5 in such a way that it can perform an oscillating movement or oscillation around a starting position indicated by the line A-A. This means that the hammer end clamped in the holder is also deflected around this line.

Im Punkt 6 ist ein Verbindungsglied 7 drehbar.an den Schlitten angeschlossen. Das andere Ende des Gliedes 7 ist, ebenfalls drehbar, im Punkt 8 mit einer Druckluftzylinderanordnung 9 verbunden, die eine seitliche Auslenkung des Verbindungsgliedes 7 (in Fig. 1 nach links) ermöglicht. Eine justierbare hydraulische Steuervorrichtung 10 kontrolliert die Rückführung des Gliedes 7 in seine in Fig. 1 dargestellte Ausgangslage, in der das Glied 7 und der Schlitten mit der Halterung 3 auf einer Geraden liegen, die im weiteren als Mittellinie bezeichnet wird.At point 6, a link 7 is rotatably connected to the carriage. The other end of the link 7, also rotatable, is connected at point 8 to a compressed air cylinder arrangement 9, which enables the link 7 to be deflected laterally (to the left in FIG. 1). An adjustable hydraulic control device 10 controls the return of the link 7 to its initial position shown in FIG. 1, in which the link 7 and the slide with the holder 3 lie on a straight line, which is referred to hereinafter as the center line.

Um das Verbindungsglied 7 in eine Hin- und Herbewegung (in Fig. 1 auf und ab) zu versetzen, ist ein Hebel 11 vorgesehen. Dieser kann eine oszillierende Bewegung um einen festen Punkt 15 ausführen, der auf der genannten Mittellinie liegt. Am anderen Ende des Hebels 11 befindet sich ein Nockenstössel 12a, der der Nockenkurve 12 einer Nockensteuerung 13 folgt. Die Nockensteuerung 13 wird durch eine Antriebsvorrichtung 14 angetrieben und läuft während des Betriebs der Vorrichtung kontinuierlich um. Somit bewegt sich das linke Ende des Hebels 11 auf und ab (in Fig. 1 gestrichelt angedeutet).In order to set the connecting member 7 in a back and forth movement (up and down in FIG. 1), a lever 11 is provided. This can perform an oscillating movement around a fixed point 15, which lies on said center line. At the other end of the lever 11 there is a cam follower 12a, which follows the cam curve 12 of a cam control 13. The cam controller 13 is driven by a drive device 14 and rotates continuously during the operation of the device. The left end of the lever 11 thus moves up and down (indicated by dashed lines in FIG. 1).

In Fig. 2 ist die Verbindung zwischen Verbindungsglied 7 und Hebel 11 dargestellt. Mit 15 ist der feste Drehpunkt des Hebels 11 bezeichnet. Er wird durch einen mit dem Maschinenrahmen fest verbundenen Achsstummel gebildet, der in ein im Hebel 11 vorgesehenes (gestrichelt angedeutetes) Loch eingreift. Wie erwähnt, liegt der Punkt 15 auf der oben definierten Mittellinie des Gliedes 7 und der Halterung 3.In Fig. 2 the connection between the link 7 and lever 11 is shown. 15 with the fixed pivot point of the lever 11 is designated. It is formed by an axle stub which is firmly connected to the machine frame and engages in a hole provided in the lever 11 (indicated by dashed lines). As mentioned, the point 15 lies on the center line of the link 7 and the holder 3 defined above.

In der dem Betrachter zugewandten Oberfläche des Hebels 11 befindet sich eine bogenförmige Nut lla. Sie bildet einen Teil eines Kreises mit dem Radius R, dessen Mittelpunkt mit dem Drehpunkt 6 zusammenfällt. Die Nut beginnt im Drehpunkt 15.There is an arcuate groove 11a in the surface of the lever 11 facing the viewer. It forms part of a circle with the radius R, the center of which coincides with the fulcrum 6. The groove begins at fulcrum 15.

Ein'am Verbindungsglied 7 angebrachter Mitnehmerstift 16 wird in die Nut lla geführt. Er bewegt sich in der Nut, wenn das Glied 7 durch die Einrichtungen 9 und 10 um den Drehpunkt 6 ausgelenkt wird.A driver pin 16 attached to the connecting member 7 is guided into the groove 11a. It moves in the groove when the link 7 is deflected about the pivot point 6 by the devices 9 and 10.

Solange sich die Druckluftzylinderanordnung 9 und somit das Glied 7 und die Halterung 3 in der in Fig. 1 gezeigten Ausgangslage befinden, wird die oszillierende Bewegung des Hebels 11 um den Punkt 15 nicht auf das Glied 7 oder die Halterung 3 übertragen. Wird jedoch das Glied 7 durch die Anordnung 9 nach links ausgelenkt, so wird der Mitnehmerstift 16 vom Festpunkt 15 wegbewegt. Je weiter der Stift von 15 entfernt wird, so grösser wird die Amplitude der oszillierenden Bewegung des Stiftes 16 und damit auch die des Verbindungsgliedes 7 und der Halterung 3. Letztere wird um ihre Ausgangslage A-A hin- und herbewegt.As long as the compressed air cylinder arrangement 9 and thus the link 7 and the holder 3 are in the starting position shown in FIG. 1, the oscillating movement of the lever 11 around the point 15 is not transmitted to the link 7 or the holder 3. However, if the link 7 is deflected to the left by the arrangement 9, the driver pin 16 is moved away from the fixed point 15. The farther the pin away from 15 becomes, the greater the amplitude of the oscillating movement of the pin 16 and thus also that of the connecting member 7 and the holder 3. The latter is moved back and forth about its starting position AA.

Das Ausrichten des Hammers 1 erfolgt, indem das in der Halterung 3 des Schlittens befestigte Hammerende um die Mittellage A-A hin- und herbewegt wird. Begonnen wird mit einer maximalen Schwingungsamplitude, bei der die Streckgrenze des Hammermaterials gerade überschritten wird. Dann wird die Amplitude kontinuierlich reduziert, bis sie den Wert Null erreicht und der Fchlitten auf der Mittellage zum Stillstand kommt.The hammer 1 is aligned by moving the hammer end fastened in the holder 3 of the slide back and forth around the central position A-A. It starts with a maximum vibration amplitude at which the yield strength of the hammer material is just exceeded. Then the amplitude is continuously reduced until it reaches zero and the slide on the middle position comes to a standstill.

Mit der beschriebenen Anordnung werden diese Operationen ausgeführt, indem zunächst das Verbindungsglied 7 durch die Druckluftzylinderanordnung 9 gerade soweit ausgelenkt wird, dass die Amplitude der Schwingungen der Halterung 3 das vorgesehene Maximum erreicht. Gesteuert durch die Vorrichtung 10 bewegt sich dann das Glied 7 in Richtung seiner Ausgangslage zurück. Hierbei reduziert sich die Amplitude der Schlittenbewegungen kontinuierlich und wi d schliesslich zu Null, wenn Glied 7 in die Ausgangslage zurückgekehrt ist.With the arrangement described, these operations are carried out by first deflecting the connecting member 7 through the compressed air cylinder arrangement 9 to such an extent that the amplitude of the vibrations of the holder 3 reaches the intended maximum. Controlled by the device 10, the link 7 then moves back in the direction of its starting position. Here, the amplitude of the carriage movements is continuously reduced and finally wi d to zero when link 7 has returned to the starting position.
