Description
Presse mit kniehebelbetätigtem Tiegel Die Erfindung bezieht sich auf eine Presse zum Prägen, Stanzen od. dgl. von Werkstücken, z. B. aus Papier, Pappe, Kunststoff, mit einem fest angeordneten Tiegel und einem sich auf diesem abwälzenden, entsprechend der Abwälzbewegung gewölbten Tiegel sowie mit mindestens zwei an diesem Tiegel angreifenden, einander gegenüber angeordneten Kniehebeln und mit einer mit diesen Kniehebeln über exzentrisch gelagerte Antriebsmittel zusammenwirkenden Welle und mit einem die Tiegelbewegung sichernden Gleitstück.Press with toggle-operated crucible The invention relates to a press for embossing, punching or the like of workpieces, e.g. B. made of paper, cardboard, Plastic, with a fixed crucible and a rolling on this, crucibles curved according to the rolling movement and with at least two on this Crucible attacking, oppositely arranged toggle levers and with one with these toggle levers via eccentrically mounted drive means cooperating shaft and with a sliding piece that secures the movement of the crucible.
Zum leichteren Verständnis sei eine Presse dieser bekannten Gattung in F i g. 1 der Zeichnung kurz erläutert. Das Pressengerüst 1 trägt einen flachen, unbeweglichen oberen Tiegel 2, gegen welchen der gewölbte untere beweg liehe: Tiegel 3 durch eine abrollende. Bewegung angedrückt wird.To make it easier to understand, consider a press of this well-known type in Fig. 1 of the drawing briefly explained. The press frame 1 carries a flat, immovable upper crucible 2, against which the curved lower crucible was movable: crucible 3 by an unwinding. Movement is pressed.
Dieses Andrücken findet unter der Einwirkung von vier Kniehebeln 4 und 5 statt, die durch Stangen 6 und 7, welche mittels gleichachsiger Exzenter der Antriebswelle 8 in Bewegung gesetzt werden, angetrieben sind. Die Welle 8 führt eine Umdrehung pro Arbeitsgang aus. Im dargestellten Beispiel wird diese Welle mittels eines .Schneckenrades 9 über eine Schnecke 10 der Motorwelle 1 mit Schwungrad 12 angetrieben, wobei der Motor selbst nicht dargestellt ist.This pressing takes place under the action of four toggle levers 4 and 5 held by rods 6 and 7, which by means of equiaxed eccentrics of the Drive shaft 8 are set in motion, are driven. The wave 8 leads one revolution per operation. In the example shown, this wave is made using a .Schneckenrades 9 via a worm 10 of the motor shaft 1 with flywheel 12 driven, the motor itself is not shown.
Bei Pressen dieser Gattung ist es bekannt, die Tiegelbewegung durch ein Gleitstück in gekrümmter Führungsbahn zu sichern.In presses of this type, it is known to move the crucible through to secure a slider in a curved guideway.
Der einwandfreie Gang einer derartigen Anordnung stellt ein Problem dar, das bis jetzt nur durch komplizierte Mittel gelöst wurde, insbesondere durch schwer zu berechnende und auszuführende Leitkurven und profilierte Führungen. Es handelt sich in der Tat um sehr komplexe Bewegungsgesetze. Während die Kniehebel ihre Hübe nacheinander ausführen und den beweglichen Tiegel am fest angeordneten Tiegel andrücken, muß der bewegliche Tiegel derart schaukeln, daß seine gewölbte Arbeitsfläche eine gleitfreie Abrollbewegung entlang der flachen Arbeitsfläche des unbeweglichen Tiegels ausführt, wonach die Kniehebel beide Tiegel derart voneinander zu entfernen haben, daß das bearbeitete Werkstück entfernt bzw. ein neues zwischen den , Tiegeln eingeführt werden kann, z. B. mit Hilfe von querliegenden Greiferstangen 13, die durch endlose Ketten 14 geführt sind.The proper operation of such an arrangement poses a problem which until now has only been solved by complicated means, in particular by Guide curves and profiled guides that are difficult to calculate and execute. It are in fact very complex laws of motion. While the knee lever Carry out their strokes one after the other and the movable crucible on the fixed Pressing the crucible, the movable crucible must rock so that its curved Work surface a smooth rolling movement along the flat work surface of the Executes immovable crucible, after which the toggle levers both crucibles from each other have to remove that the machined workpiece removed or a new one between the crucibles can be introduced, e.g. B. with the help of transverse gripper bars 13, which are guided by endless chains 14.
Die der Erfindung zugrunde liegende Aufgabe besteht darin, eine Presse der vorbeschriebenen Gattung ; zu schaffen, deren Steuermittel einfacher sind und leichter mit großer Genauigkeit herstellbar sind. Gelöst wird diese Aufgabe erfindungsgemäß in vorteilhafter Weise dadurch, daß das Gleitstück in einem Schwenkhebel angeordnet und auf der die Kniehebel über Stangen betätigenden Welle eine Leitkurve vorgesehen ist.The object of the invention is to provide a press of the genus described above; to create whose control means are simpler and are easier to manufacture with great accuracy. This object is achieved according to the invention advantageously in that the slider is arranged in a pivot lever and a guide cam is provided on the shaft which actuates the toggle levers via rods is.
Die F i g. 2 bis 4 zeigen diese neue Presse in schematischer Darstellung sowohl in der Ausgangslage, einer Mittellage und der Endlage des beweglichen Tiegels bei fest angeordnetem Tiegel, d. h. den verschiedenen Stellungen des beweglichen Tiegels während des Anpreßvorganges.The F i g. 2 to 4 show this new press in a schematic representation both in the starting position, a central position and the end position of the movable crucible with the crucible in a fixed position, d. H. the various positions of the movable Crucible during the pressing process.
Die F i g. 5 ist ein Schnitt gemäß V-V der F i g. 6, die ihrerseits einem Schnitt nach VI-VI der F i g. 5 entspricht. Es zeigen diese Figuren eine besondere, weiter unten beschriebene Ausführungsform des Erfindungsgegenstandes.The F i g. 5 is a section according to V-V of FIG. 6 for their part a section according to VI-VI of FIG. 5 corresponds. These figures show a special, Embodiment of the subject matter of the invention described below.
In den F i g. 2 bis 4 trägt die Hauptwelle 15, die je eine Umdrehung pro Arbeitsgang ausführt, eine Leitkurve 16. Eine zweite, genau gleiche Leitkurve liegt am anderen Ende.In the F i g. 2 to 4, the main shaft 15, which executes one revolution per operation, carries a guide curve 16. A second, exactly identical guide curve is located at the other end.
Voneinander abgewendete .Stangen 17, 18 sind bei 19 bzw. 20 mit der Welle 15 drehbar verbunden und betätigen die beiden Kniehebel 21 bzw. 22, die ihrerseits den beweglichen Tiegel 23 heben und senken. Seine Arbeitsfläche ist gewölbt und wirkt mit der unteren flachen Seite des oberen unbeweglichen Tiegels 24 zusammen. Rods 17, 18 facing away from each other are rotatably connected to shaft 15 at 19 and 20 respectively and actuate the two toggle levers 21 and 22, which in turn raise and lower the movable crucible 23. Its work surface is curved and cooperates with the lower flat side of the upper immovable crucible 24 .
Die Drehpunkte 19 und 20, die im vorliegenden Fall zwischen sich einen Winkel von 90° einschließen, drehen mit der Welle 15 in Richtung des Pfeiles 25, so daß der Tiegel 23 eine pendelnde Bewegung ausführt, im Laufe welcher zuerst die rechte Seite (mit Bezug auf die Zeichnung) am oberen Tiegel 24 angedrückt wird, dann sein mittlerer Teil (F i g. 3), endlich seine linke Seite (Fi g. 4), wonach er in die Ausgangslage verschwenkt wird unter gleichzeitigem Entfernen vom oberen Tiegel.The pivot points 19 and 20, which in the present case enclose an angle of 90 ° between them, rotate with the shaft 15 in the direction of arrow 25, so that the crucible 23 executes a pendulum movement, in the course of which the right side (with reference to on the drawing) is pressed against the upper crucible 24, then its middle part (Fig. 3), finally its left side (Fig. 4), after which it is pivoted into the starting position while at the same time removing it from the upper crucible.
Werden die Kniehebel, die Stangen und der Winkel zwischen den Drehpunkten 19 und 20 entsprechend bemessen, so kann ein vollkommenes Anliegen des unteren Tiegels am oberen Tiegel über die ganze Arbeitsfläche erreicht werden, aber nicht in Gestalt eines gleitlosen Abrollens. Um das Gleiten zu verhindern, ist es notwendig, den Tiegel 23 zwangläufig zu führen, wozu unter anderem die Leitkurve 16 dient.If the toggle levers, the rods and the angle between the pivot points 19 and 20 are dimensioned accordingly, the lower crucible can be completely in contact with the upper crucible over the entire work surface, but not in the form of a smooth rolling. In order to prevent sliding, it is necessary to positively guide the crucible 23 , for which purpose the guide curve 16 is used, among other things.
Gegen diese Leitkurve stützt sich das freie untere Ende eines Hebels 26, welcher sich um einen Festpunkt 27 dreht, der unterhalb der Arbeitsfläche des zu führenden Tiegels 23 liegt.The free lower end of a lever is supported against this guide curve 26, which rotates around a fixed point 27, which is below the work surface of the to leading crucible 23 is located.
Oberhalb dieses Dreh- und Festpunktes weist der Hebel eine mit diesem starr verbundene Verlängerung auf, mit welcher er ein Gleitstück 28 führt, das seinerseits in einer Führung 29 des Tiegels gleitet, die diesen in Richtung seiner Symmetrieebene halbiert.Above this fulcrum and fixed point, the lever has one with this rigidly connected extension, with which he leads a slider 28, which in turn in a guide 29 of the crucible slides this in the direction of its plane of symmetry halved.
Der Tiegel kann somit in bezug auf dieses Gleitstück gleiten, aber auch mit diesem letzteren und um seinen Befestigungspunkt am oberen Ende des Hebels 26 drehen.The crucible can thus slide with respect to this slide, but also with this latter and around its attachment point at the upper end of the lever 26 turn.
In der Ausgangslage der F i g. 2 liegt das Gleitstück 28 in seiner äußersten rechten Lage, da der Hebel 26 im Bereich der kleinsten Exzentrizität der Leitkurve, praktisch auf der Halbierenden des durch die Drehpunkte 19 und 20 umschlossenen Winkels ; liegt. Nach etwa einem Viertel -einer Umdrehung der Welle 15 (mittlere Lage nach F i g. 3) liegt die Mitte des bewglichen Tiegels am unbeweglichen Tiegel an. Die beiden Kniehebel sind gleich viel ausgespreizt, und das Gleitstück 28 liegt in der lotrechten Symmetrieachse x-y, -so daß alle Bestandteile, mit Ausnahme des Hebels 26, beidseitig dieser Achse symmetrisch angeordnet sind.In the starting position of FIG. 2, the slider 28 is in its extreme right position, since the lever 26 is in the region of the smallest eccentricity of the guide curve, practically on the bisector of the angle enclosed by the pivot points 19 and 20; lies. After about a quarter of a revolution of the shaft 15 (middle position according to FIG. 3) the center of the movable crucible rests against the immovable crucible. The two toggle levers are spread out equally, and the slider 28 lies in the vertical axis of symmetry xy, so that all components, with the exception of the lever 26, are arranged symmetrically on both sides of this axis.
Nach etwa einer halben Umdrehung erhält man die Lage der F i g. 4, die derjenigen der F i g. 2 entgegengesetzt ist und dem Andrücken des linken Teiles des Tiegels 23 gegen den Tiegel 24 entspricht. Dabei ist das Gleitstück 28 um den gleichen Betrag nach links versetzt, um den es bei der Lage nach F i g. 1 nach rechts versetzt war. Gleichzeitig nimmt die Leitkurve 16 die Lage ihrer größten Exzentrizität ein.After about half a turn, the position of FIG. 4, that of those of FIG. 2 is opposite and corresponds to the pressing of the left part of the crucible 23 against the crucible 24 . The slider 28 is offset to the left by the same amount as it is in the position according to FIG. 1 was offset to the right. At the same time, the guide curve 16 assumes the position of its greatest eccentricity.
Die Abmessungen der Leitkurve des Hebels 26 und die Lage des Drehpunktes des Gleitstücks 28 lassen sich ohne weiteres so wählen, daß die so erhaltene Führung den unteren Tiegel 23 dazu zwingt, sich am oberen Tiegel 24 genau, d. h. ohne Gleiten, abzurollen.The dimensions of the guide curve of the lever 26 and the position of the pivot point of the slider 28 can easily be selected so that the guide thus obtained Forcing the lower crucible 23 to exactly, i. H. without sliding, to roll off.
Während der zweiten halben Umdrehung der Welle 15 gehen die Drehpunkte 19 und 20 in einem gewissen Augenblick durch eine untere Lage, die der oberen Lage der F i g.. 3 symmetrisch ist.During the second half revolution of the shaft 15, the pivot points go 19 and 20 at a certain moment by a lower layer, that of the upper layer the F i g .. 3 is symmetrical.
Der Drehpunkt 19 liegt dann rechts und der Drehpunkt 20 links, d. h., es liegen die Mitten beider Kniehebel so nah wie möglich aneinander (am weitesten entfernt sind sie in F i g. 3), und es werden beide Enden des Tiegels gleichzeitig gesenkt. Es entsteht ein freier Raum zwischen den beiden Tiegeln, durch welche das zu bearbeitende Material hindurchgeführt werden kann.The pivot point 19 is then on the right and the pivot point 20 on the left, i.e. In other words, the centers of both knee levers are as close to each other as possible (furthest they are removed in FIG. 3), and it will both ends of the crucible at the same time lowered. A free space is created between the two crucibles through which the material to be processed can be passed through.
Nun sei an Hand der Ansichten und geschnittenen Teile der F i g. 5 und 6 in einem Beispiel gezeigt, wie die soeben geschilderte Führung des beweglichen Tiegels praktisch verwirklicht werden kann.Now, on the basis of the views and cut parts of FIG. 5 and FIG. 6 shows an example of how the just described guidance of the movable Crucible can be realized in practice.
Im beweglichen Tiegel 30 ist eine geradlinige Nut 31 vorgesehen, die dem Gleitblock 32 (entsprechend 28 in den F i g. 2 bis 4) als Führung dient und der vorangehend beschriebenen Führung 29 entspricht. Mit 33 ist die die Arbeitsfläche des Tiegels bildende Werkzeugplatte bezeichnet.A straight groove 31 is provided in the movable crucible 30 , which serves as a guide for the slide block 32 (corresponding to 28 in FIGS. 2 to 4) and corresponds to the guide 29 described above. The tool plate which forms the working surface of the crucible is designated by 33.
Der Tiegel wird, wie bereits beschrieben, mittels Kniehebeln gehoben und gesenkt, die ihrerseits durch eine Hauptwelle 34, die je eine Umdrehung pro Arbeitsgang ausführt, angetrieben sind. An der Hauptwelle ist die Leitkurve 35 angeordnet, die auf den Hebel 36 wirkt, welcher mittels des Zapfens 37 mit dem Block 32 gelenkig verbunden ist.As already described, the crucible is lifted using toggle levers and lowered, in turn by a main shaft 34, each one revolution per Performing operation, are driven. The guide curve 35 is arranged on the main shaft, which acts on the lever 36, which is articulated to the block 32 by means of the pin 37 connected is.
Die Mitte dieses Hebels 36 dreht um die Achse des Zapfens 38, die an einem Teil 39 des Pressengerüstes unbeweglich liegt. Befestigungsschrauben, die durch ihre Achsenlinien 40 dargestellt sind, halten den Zapfen 38 mit Hilfe des Kopfes 41 am Pressenteil 39 fest. Ein gleichartiger Kopf 42 und ähnliche Schrauben 43 halten einen Zapfen 37 am Ende des verlängerten Armes des Hebels 36. Eine Feder 44 drückt die Rolle 45 an die Leitkurve 35 an.The center of this lever 36 rotates about the axis of the pin 38, which is immovable on a part 39 of the press frame. Fastening screws, which are represented by their axis lines 40, hold the pin 38 firmly on the press part 39 with the aid of the head 41. A similar head 42 and similar screws 43 hold a pin 37 at the end of the extended arm of the lever 36. A spring 44 presses the roller 45 against the guide cam 35.
Während also die Welle 34 eine Umdrehung ausführt, erteilt die Leitkurve 35 dem Hebel eine einmalige pendelnde Bewegung um die Achse des Zapfens 38.So while the shaft 34 executes one revolution, issued the guide curve 35 the lever a single oscillating movement about the axis of the pin 38.
Eine gleichartige Anordnung befindet sich auch an dem anderen Ende der Welle 34.A similar arrangement is also found at the other end of shaft 34.
Der Block 32 ist entbehrlich, wenn man den Durchmesser des Zapfens 37 entsprechend der Breite der Nut 31 bemißt.The block 32 is unnecessary if you consider the diameter of the pin 37 dimensioned according to the width of the groove 31.
Die Leitkurve 35 kann auch ein einfacher Exzenter sein. Der Hebel 36 kann gabelförmig ausgebildet sein, so daß er den Exzenter umfaßt, wobei die Feder 44 nicht mehr erforderlich ist.The guide curve 35 can also be a simple eccentric. The lever 36 can be fork-shaped so that it includes the eccentric, the spring 44 is no longer required.
