Die Erfindung betrifft eine Vorrichtung
mit den Merkmalen nach dem Oberbegriff von
Anspruch 1.The invention relates to a device
with the features according to the preamble of
Perforierte Bleche werden in großem Umfang in zahlreichen Industriezweigen verwendet, nämlich als Siebe und Filter in der Nahrungsmittelindustrie, im Bergbau und in Kiesgruben, als Schutzabdeckungen bei Phonogeräten, Bau- und Werkzeugmaschinen, als Trennwände und Dekorationen, als Bauelemente in Haushaltgeräten, bei Büromöbeln, in Flugzeugen und im Industriebau.Perforated sheets are widely used in numerous industries, namely as Sieves and filters in the food industry, in Mining and in gravel pits, as protective covers Phono devices, construction and machine tools, as partitions and decorations, as components in household appliances, in office furniture, in aircraft and in Industrial building.
Zum Perforieren von Blechen aus Stählen, NE-Metallen, oder Werkstoffkombinationen in Blechdicken zwischen 0,3 und 30 mm werden grundsätzlich zwei Arten von Pressen eingesetzt, und zwar Perforier-Breitpressen, um Bleche mit durchgehenden oder periodisch unterbrochenen Lochmustern aus Band- oder Tafelmaterial in Serie zu fertigen, und Streifenpressen, um Einzeltafeln, größere Blechformate und -Dicken mit individuellen Lochmustern herzustellen. (WT Werkstattstechnik, Band 79: 587 - 590; 1989, und Band 80: 77 - 79, 1990, Springer-Verlag Berlin Heidelberg)For perforating steel sheets, non-ferrous metals, or material combinations in sheet thicknesses between 0.3 and 30 mm are basically two types of presses used, namely perforating wide presses to sheet with continuous or periodically interrupted hole patterns from tape or sheet material in series manufacture, and strip presses, to single sheets, larger ones Sheet formats and thicknesses with individual hole patterns to manufacture. (WT Werkstattstechnik, Volume 79: 587 - 590; 1989, and Vol. 80: 77-79, 1990, Springer-Verlag Berlin Heidelberg)
Während sich bei einer Streifenpresse die Blechtafeln mit einem Aufspanntisch in zwei senkrecht zueinander stehenden Koordinaten relativ zum Perforierwerkzeug bewegen lassen, fördern bei einer Perforier-Breitpresse Vorschubwalzen die Blechtafeln oder -bänder zwischen einem Oberwerkzeug, in der Regel einer Vielzahl von Stempeln, und einem Unterwerkzeug, einer Matrize, schrittweise synchron zum Arbeitstakt der Presse in einer Vorschubrichtung hindurch.While the sheet metal is in a strip press with a clamping table in two perpendicular to each other standing coordinates relative to the perforating tool Let move, convey with a perforating wide press Feed rolls between the sheets or strips an upper tool, usually a variety of Stamping, and a lower tool, a die, step by step in sync with the press in a feed direction.
Die Stempel der Perforier-Breitpresse sind in Reihen quer zur Vorschubrichtung angeordnet. Sie sind in einem Stempelhalter geführt. Ein Stößel der Presse schiebt sie durch eine Stempelführungsplatte hindurch und drückt sie durch das Blech in entsprechende Löcher der Matrize. Ein Abstreifer verhindert, daß das Blech beim Zurückziehen der Stempel an diesen hängen bleiben. Er ist starr oder wird phasenverschoben zum Stößel betätigt.The punches of the perforating wide press are in rows arranged transversely to the feed direction. You are in one Stamp holder led. A ram pushes the press them through a stamp guide plate and presses them through the sheet into corresponding holes in the Die. A scraper prevents the sheet from Withdrawing the stamp will stick to it. He is rigid or becomes out of phase with the pestle operated.
Es ist aus der DE-A1 41 35 787 bekannt, die Stempel einzeln anzusteuern und zu aktivieren, um das Lochmuster während eines Arbeitsvorgangs zu variieren. Dies wird mit einem Steuerschieber erreicht, der oberhalb der Stempel in Vorschubrichtung oder entgegengesetzt in den Kraftfluß zwischen dem Stößel und einzelner Stempel ein- oder ausgerückt wird. Ist der Steuerschieber eingerückt, ist der entsprechende Stempel aktiviert und stanzt ein Loch in das Blech; ist der Steuerschieber ausgerückt, ist der Kraftfluß zu dem entsprechenden Stempel unter-brochen und der Stempel führt einen Leerhub aus.It is known from DE-A1 41 35 787, the stamp individually controlled and activated to the Varying lace patterns during an operation. This is achieved with a control spool that above the stamp in the feed direction or opposite in the flow of force between the plunger and single stamp is indented or disengaged. Is the control spool is engaged, is the corresponding one Stamp activates and punches a hole in the sheet; is the spool is disengaged, the flow of power to that the corresponding stamp is interrupted and the stamp performs an idle stroke.
Mit der bekannten Einrichtung können zwar komplexe Lochbilder hergestellt werden, jedoch ist sie wegen der zahlreichen Steuerschieber und der zugehörigen Stellglieder sehr aufwendig.With the known device can be complex Hole patterns are made, however, it is because of numerous control spools and the associated actuators very complex.
Desweiteren ist aus der DE-U-94 19 403 (nächstliegender Stand der Technik) eine Perforiereinrichtung in einer Presse für bandförmiges Feinblech mit einer Vorschubeinrichtung zum schrittweisen Fördern eines Bleches durch die Perforierstufe bekannt. Das Blech wird während einer Rastphase mittels eines Werkzeugs aus Matrize und Stempel gelocht. Hierbei sind ein oder mehrere Steuerschieber vorgesehen, die jeweils in Vorschubrichtung des Bleches ein oder mehrere Stempelreihen überdecken können, die quer zur Vorschubrichtung des Bleches verschiebbar sind und so je nach Position den Kraftfluß zu einem oder mehreren Stempeln herstellen bzw. unterbrechen. Die Steuerschieber sind in Vorschubrichtung des Bleches zueinander versetzt und überlappend angeordnet voneinander unabhängig verschiebbar.Furthermore, from DE-U-94 19 403 (closest prior art) a perforating device in a press for strip-shaped thin sheet with a feed device for gradual conveying of a sheet known through the perforation stage. The sheet is held during a rest phase by means of a Perforated tool from die and stamp. Here are one or more spools provided, each one or more rows of stamps in the feed direction of the sheet can cover, which can be moved transversely to the feed direction of the sheet and so depending Establish or interrupt the flow of force to one or more stamps according to position. The control slides are offset from one another in the feed direction of the sheet metal and overlap arranged independently of each other.
Der Erfindung liegt die Aufgabe zugrunde, mit einfachen Mitteln gängige Lochmuster in Serie herzustellen, die in Vorschubrichtung einen zu- und/oder abnehmenden lochfreien Bereich haben können, z.B. Kreise, Dreiecke, Trapeze usw..The invention has for its object with simple Medium to manufacture common hole patterns in series, the an increasing and / or decreasing in the feed direction can have a hole-free area, e.g. Circles, triangles, Trapezoids etc.
Sie wird gemäß der Erfindung durch die Merkmale des
Anspruchs 1 gelöst.It is according to the invention by the features of
Bei dieser Vorrichtung gemaß Anspruch 1 kann z. B. ein Steuerschieber von einer Seite quer zur Vorschubrichtung schrittweise in den Kraftfluß geschoben werden, so daß nach jedem Vorschub ein oder mehrere Stempel zusätzlich aktiviert werden. Es entstehen so dreieckige oder trapezförmige Lochmuster. Ist der Steuerschieber kürzer als die zugehörige Stempelreihe und wird er schrittweise hin und her verschoben, lassen sich schlangenförmige Lochmuster erzeugen.In this device according to claim 1 z. B. a Control spool from one side transverse to the feed direction gradually pushed into the power flow be so that after each feed one or more Stamp can also be activated. It arises like this triangular or trapezoidal lace pattern. Is the Control spool shorter than the associated row of punches and if it is gradually moved back and forth, let create serpentine hole patterns.
Vorteilhaft ist, daß mit einem einzigen Steuerschieber schon viele häufig gewünschte Lochmuster hergestellt werden können. Ferner können Stempel noch separat aktiviert werden, selbst wenn sie nur einen geringen Abstand voneinander haben, da der Steuerschieber in beliebig kleinen Schritten verstellt werden kann. Hierzu dient zweckmäßigerweise ein elektrischer oder hydraulischer Schrittmotor, der über Ritzel, Zahnriemen und eine Zahnstange, die am Steuerschieber befestigt ist, diesen antreibt.It is advantageous that with a single spool already made many frequently requested hole patterns can be. Furthermore, stamps can still be separately be activated even if they are only a small one Be at a distance from each other since the control spool in any small steps can be adjusted. An electrical or expediently serves this purpose hydraulic stepper motor, via pinion, toothed belt and a rack that attaches to the spool is driving this.
In einfacher Weise wird der Schrittmotor am Stößel direkt montiert, so daß er die Bewegung des Stößels mitmacht und keine Relativbewegung zwischen dem Stößel und dem Schrittmotor zu berücksichtigen ist. Um aber Erschütterungen oder Schwingungen vom Schrittmotor fernzuhalten, ist es vorteilhaft diesen am Pressenkörper zu befestigen und die dadurch entstehende Relativbewegung beim Stößelhub durch eine Schiebehülse auszugleichen, die teleskopartig mit einer Antriebsspindel zusammenarbeitet.In a simple way, the stepper motor on the plunger mounted directly so that he can move the plunger participates and no relative movement between the plunger and the stepper motor has to be considered. But around Shocks or vibrations from the stepper motor it is advantageous to keep it away from the press body to attach and the resulting Relative movement during ram stroke through a sliding sleeve to compensate, the telescopic with a drive spindle works together.
Weitere Lochmuster, z. B. Kreise, Ellipsen, Parabeln usw., können mit mehreren Steuerschiebern hergestellt werden, die gemeinsam oder je nach Muster getrennt voneinander verstellt werden können. Sie werden zweckmäßigerweise in Vorschubrichtung versetzt zueinander und überlappend angeordnet. Ferner kann jedem Steuerschieber eine oder mehrere Stempelreihen gleicher oder unterschiedlicher Länge zugeordnet werden. Dabei können die Stirnpartien der Steuerschieber so ausgebildet sein, daß beim Verschieben zunächst nur ein Stempel einer Stempelreihe aktiviert wird.More lace patterns, e.g. B. circles, ellipses, parabolas etc., can be made with multiple spools be that together or separately depending on the pattern can be adjusted from each other. You will be expedient offset to each other in the feed direction and arranged overlapping. Furthermore, each spool can one or more rows of stamps of the same or different lengths can be assigned. You can the front parts of the spool are designed in this way be that only one stamp when moving a row of stamps is activated.
Noch komplexere Lochmuster lassen sich durch die Verwendung von Stempeln unterschiedlicher Länge herstellen, wobei die Steuerschieber sich an mehreren übereinander liegenden Leisten abstützen, die gegeneinander in verschiedene Positionen verstellt werden können. Jeder Position ist eine Gesamtstärke in Hubrichtung vorgegeben, die auf die Stempellängen so abgestimmt ist, daß nur die Stempel aktiv sind, die lang genug sind, bei der gegebenen Gesamtstärke das Blech zu durchdringen.Even more complex hole patterns can be created using Make stamps of different lengths, whereby the control spools are located on top of each other Support strips that are against each other in different Positions can be adjusted. Everyone's position a total thickness in the stroke direction is given on the stamp lengths are matched so that only the Stamps are active that are long enough at the given total thickness to penetrate the sheet.
