Description
Die Erfindung betrifft eine Besäumschere für Walzbleche nach "°m Oberbegriff des Patentanspruches. Sie geht damit aus von der japanischen Gebrauchsmuster- Auslegeschri-ft 2526 '4-1, in der eine zum Besäumen von Wa'.zblecher venvendbare Schere beschrieben ist, deren Quermesser-Anordnung zum Abtrennen der Saumstreifen eine sogenannte Maulschere ist. Da die Schwenkachse des das obere Quermesser tragenden Schwenkhebels etwa parallel zu den Langmessern verläuft, ist mit Sicherheit zu erwarten, daß das obere Quermesser beim Rückhub nach erfolgtem Saumstreifenschnitt die an seiner Brustfläche anliegende Schneidkante des noch am Blech hängenden Saumstreifens nach oben mitnimmt und aufwärts verbiegt. Ein weiterer Vorschubschritt des Bleches kann hierdurch unmöglich werden.The invention relates to trimming shears for rolled sheets according to the preamble of the claim. It is based on the Japanese utility model Auslegeschri-ft 2526 '4-1, in one Scissors that can be used for trimming wafer sheets is described, the transverse knife arrangement for severing the hem strips a so-called scissors is. Since the pivot axis of the pivot lever carrying the upper transverse knife is approximately parallel to runs along the long knives, it is to be expected with certainty that the upper transverse knife on the return stroke after the hem strip cut has been made, the cutting edge of the still on the chest surface Sheet metal hanging seam strip upwards and bends upwards. Another feed step this can make the sheet metal impossible.
Der Erfindung liegt die Aufgabe zugrunde, die Quermesser-Anordnung so zu gestalten, daß nach erfolgtem Quermesserschniu eine Art Messerrückzug wirksam wird, durch den das obere Quermesser im Aufwärtsgang von der Schnittkante des Saumstreifens freikommt, so daß beim nächsten Blechvorschub der Saumstreifen die Scherenöffnung der Quermesser ungehindert passieren kann. Diese Aufgabe wird durch die im Kennzeichen des Patentanspruches beschriebenen Mittel gelöst.The invention is based on the object of designing the transverse knife arrangement so that after it has taken place Quermesserschniu a kind of knife retraction is effective, through which the upper cross knife in the Upward gear comes free from the cut edge of the hem strip, so that the next sheet feed the seam strip can pass the scissor opening of the cross knife unhindered. This task is achieved by the means described in the characterizing part of the claim.
In der Zeichnung ist eine Besäumschere gemäß der Erfindung in einem Ausführungsbeispiel dargestellt, und zwar zeigtIn the drawing, a trimmer according to the invention is shown in one embodiment, namely shows
F i g. 1 eine teilweise Vorderansicht,F i g. 1 is a partial front view,
F i g. 2 einen senkrechten Schnitt durch die Quermesser-Anordnung nach der Linie IT-II in Fig. 1 undF i g. 2 shows a vertical section through the transverse knife arrangement according to the line IT-II in Fig. 1 and
F i g. 3 einen Schnitt nach der Linie III-III in Fig. 2.F i g. 3 shows a section along the line III-III in FIG Fig. 2.
Die wesentlichsten Teile der Besäumschere sind nach F i g. 1 der Scherensländer 10 mit Untermcsserbalken 11, der schwenkbare Obermesserträger 12 mit Obermesser 13 und die auslaufseitig angeordnete Quermesser-Anordnung mit dem Schvyenkhebel 24 für das obere Quermesser 15 und dem festen unteren Quermesser 16, das deutlich unterhalb der Oberkante 17 des unteren Langmessers 18 a.igeordnet ist.The most important parts of the trimming shears are shown in FIG. 1 of the Scherensländer 10 with lower beam 11, the pivotable upper knife carrier 12 with the upper knife 13 and the one arranged on the outlet side Cross knife arrangement with the Schvyenk lever 24 for the upper cross knife 15 and the fixed lower one Cross knife 16, which is arranged well below the upper edge 17 of the lower long knife 18 a.
Die Vorschubrichtung des Bleches ist durch den Pfeil 20 angedeutet. Fig. 1 läßt die geneigte Schneidebene der Quermesser-Anordnung 14 bis 16 erkennen, wodurch die Messerbrust 15 α des oberen Quermessers 15 beim Rückhub von der Schnittfläche eines noch am Blech hängenden Saumstreifens freikommt, wenn dieser nach dem Abtrennen eines durchgeschobenen Stückes des Saumstreifens nach oben zurückfedert. Die abgetrennten Saumstreifen fallen auf eine Rutsche 21, die die Saumstreifen auf jinen unterhalb der Schere liegenden Schrotttransport befördert.The direction of advance of the sheet is indicated by arrow 20. Fig. 1 reveals the inclined cutting plane of the transverse knife arrangement 14 to 16, whereby the knife face 15 α of the upper transverse knife 15 during the return stroke comes free from the cut surface of a hem strip still hanging on the sheet metal, when this comes up after a pushed-through piece of the hem strip is cut springs back. The cut-off seam strips fall onto a chute 21 which conveys the seam strips onto the scrap transport located below the scissors.
Im Schnitt nach F i g. 2 erkennt man einen doppelarmigen Schwenkhebel 24 mit dem Messersattel 25 für das obere Quermesser 15 sowie das untere Quermesser 16. Der Schwenkhebel ist auf einer Schwenkachse 26 gelagert, die parallel zu den Langmesseru 13, 18 verläuft, nach F i g. 3 jedoch geneigt im Scherengestell 10 angeordnet ist, und zwar in Richtung des Blechvorschubes 20 abwärts geneigt, um die aus Fig. 1 ersichtliche Schräglage der Schnittebene der Quermesser 15 und 16 einzustellen.In the section according to FIG. 2 you can see a double-armed Swivel lever 24 with the knife saddle 25 for the upper transverse knife 15 and the lower transverse knife 16. The pivot lever is mounted on a pivot axis 26 which is parallel to the Langmesseru 13, 18 runs according to FIG. 3, however, is arranged inclined in the scissors frame 10, namely in the direction of the sheet feeder 20 inclined downwards to the inclined position of the sectional plane shown in FIG Set cross knife 15 and 16.
Da erfindungsgemäß die Schwenkachse 26 unterhalb der Schneidkante des unteren Langmessers 18 liegt, beschreibt die äußerste Spitze des oberen Quermessers 15 beim Schnitt einen Kreisbogen 27, der im Abstand von der besäumten Kante des Bleches 30 verläuft. Das obere Quermesser 15 braucht damit auch in horizontaler Richtung während des Rückhubes nicht zurückgezogen zu werden, wie sich auch der Schneidbereich der beiden Quermesser erkennbar bis in die senkrechte Projektion des besäumten Bleches 30 erstrecken kann.Since, according to the invention, the pivot axis 26 is below the cutting edge of the lower long knife 18 is, describes the outermost tip of the upper transverse knife 15 when cutting a circular arc 27, which in the Distance from the trimmed edge of the sheet 30 runs. The upper transverse knife 15 thus needs not to be withdrawn even in the horizontal direction during the return stroke, as well as yourself the cutting area of the two transverse knives can be seen in the vertical projection of the trimmed sheet 30 can extend.
Das rückwärtige Ende des doppelarmigen Schwenkhebels 24 ist gegabelt und trägt einen Gelenkzapfen 28, an den über eine sphärische Büchse 29 eine Zugstange 40 angeschlossen ist. Die Zugstange 40 wird von einem großen Exzenter 42 der Kurbelwelle 41 betätigt, und zwar ebenfalls unter Zwischenschaltung einer sphärischen Büchse 43.The rear end of the double-armed pivot lever 24 is forked and carries a pivot pin 28, to which a pull rod 40 is connected via a spherical sleeve 29. The pull rod 40 is actuated by a large eccentric 42 of the crankshaft 41, also below Interposition of a spherical sleeve 43.
Der Exzenter 42 steht so, daß das obere Quermesser 15 den vom Blech 30 abgetrennten und bis auf das Niveau des unteren Quermessers 16 abwärts gedrückten Saumstreifen 31 beginnt abzuschneiden. Der Drehsinn des Exzenters 42 ist in F i g. 2 durch einen Pfeil angedeutet. Die Kurbelwelle 41 ist im übrigen die Hauptkurbelwelle, die auch den schwenkbaren Messerträger 12 betätigt.The eccentric 42 is so that the upper transverse knife 15 is separated from the sheet metal 30 and up to the level of the lower transverse knife 16, which is pressed downwardly, begins to cut off the seam strip 31. The direction of rotation of the eccentric 42 is shown in FIG. 2 indicated by an arrow. The crankshaft 41 is otherwise the main crankshaft, which also actuates the pivotable knife carrier 12.
Die Wirkungsweise der Besäumschere gemäß der Erfindung ist folgende:The mode of operation of the trimmer according to the invention is as follows:
Wenn ein Blech 30 durch die nicht dargestellten Treibrollen zwischen die Besäummesser 13 und 18 vorgeschoben ist, wird der Antrieb der Schere eingeschaltet, so daß das obere Langmesser 13 abwärts geht und einen Saumstreifen 31 einschneidet. Wie aus F i g. 1 ersichtlich ist, ist die Schneidkante des oberen Langmessers 13 am einlaufseitigen Ende gekrümmt, da diese Schneidkante im unteren Totpunkt des Messerträgers 12 aus dem Blechquerschnitt heraustreten muß. Die Antriebe für den Messerträger 12 und das Quermesser 15 sind derart gegeneinander winkelversetzt, daß das obere Quermesser 15 später zum Anschnitt kommt als das obere Langmesser 13, den Saumstreifen 31 jedoch noch während des Saum-When a sheet metal 30 is placed between the trimming knives 13 and 18 through the drive rollers, not shown is advanced, the drive of the scissors is switched on, so that the upper long knife 13 downwards goes and cuts a seam strip 31. As shown in FIG. 1 can be seen, is the cutting edge of the Upper long knife 13 curved at the inlet end, since this cutting edge in the bottom dead center of the knife carrier 12 must emerge from the sheet metal cross-section. The drives for the knife carrier 12 and the transverse knife 15 are angularly offset from one another in such a way that the upper transverse knife 15 later is cut as the upper long knife 13, but the hem strip 31 is still during the hem

Schnittes abschneidet. Beim Rückgang sowohl des Messerträgers 12 als auch des Schwenkhebels 24 überholt das obere Quermesser 15 das ubere Langmesser 13 wegen der erheblich größeren Exzentrizität des Exzenters 42 der Schrottmesser-Anordnung gegenüber dem nicht dargestellten Exzenter des Besäummesser-Antriebes. Hierdurch gelangt das obere Quermesser 15 schnell in eine obere Totpunktlage, in der der an dem Blech 30 hängende Saumstreifen 31, obwohl er etw^ in die Höhe des Bleches 30 zurückgefedert ist, nicht behindert ist. Wenn ein Yoischubschritt beendet ist, ist der Schwenkhebel ,1! durch seine obere Totpunktlage bereits hindurchgelaufen und nähert sich der dargestellten Anschnitt-Lage.Cut off. When both the knife carrier 12 and the pivot lever 24 decrease the upper transverse knife 15 overtakes the clean long knife 13 because of the considerably greater eccentricity of the eccentric 42 of the scrap knife arrangement compared to the eccentric, not shown, of the trimming knife drive. This will get the upper one Cross knife 15 quickly in an upper dead center position, in which the hem strip 31 hanging on the sheet metal 30, although it has sprung back somewhat to the level of the sheet metal 30 is not disabled. When a yoishub step is finished, is the pivot lever, 1! already passed through its top dead center position and approaches the shown gate position.
