Abstract
Description
Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruches 1.The invention relates to a method according to the preamble of Claim 1.
Bei der Herstellung von Blechteilen, z. B. für Schaltschränke oder Schaltanlagen, ist es bekannt, Blechplatten einzeln zu stanzen. Hierfür muß jede Blechplatte einzeln in die Stanzmaschine eingelegt werden, einzeln aus der Maschine entnommen werden und für die weitere Bearbeitung bzw. dem Kanten vorher gestapelt und geordnet werden. Der Stanzvorgang muß für die Zeit des Einlegens und Herausnehmens unterbrochen werden, was relativ hohe Entnahmezeiten bzw. Rüstzeiten verursacht.In the manufacture of sheet metal parts, e.g. B. for control cabinets or switchgear, it is known to individually sheet metal plates punch. For this, each sheet of metal must be individually in the Punching machine can be inserted, individually from the machine removed and for further processing or edging be stacked and organized beforehand. The punching process must be for the time of insertion and removal are interrupted, which causes relatively high removal times or set-up times.
Anschließend werden die Teile wieder einzeln gekantet und einzeln lackiert. Hierzu muß jedes Teil einzeln angefaßt werden.Then the parts are individually folded and individually painted. To do this, each part must be handled individually.
Nachteilig sind die hohen Rüst- und Fertigungszeiten auch beim Kanten und beim Bestücken der Gehänge für die weitere Oberflächenbehandlung.The high set-up and production times are also disadvantageous for Edges and when loading the hangers for the further Surface treatment.
Der Erfindung liegt die Aufgabe zugrunde ein Verfahren nach dem Oberbegriff des Anspruches 1 zu finden, das eine Reduzierung der Rüst- und Fertigungszeiten ermöglicht.The invention has for its object a method according to the Preamble of claim 1 to find a reduction in Setup and manufacturing times enabled.
Die Aufgabe der Erfindung wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst, während in den Unteransprüchen besonders vorteilhafte Weiterbildungen der Erfindung gekennzeichnet sind.The object of the invention is characterized by the Features of claim 1 solved while in the subclaims particularly advantageous developments of the invention Marked are.
Anhand der Zeichnung, in der ein Ausführungsbeispiel dargestellt ist, sollen die Erfindung, weitere Ausgestaltungen und Verbesserungen der Erfindung und weitere Vorteile näher beschrieben und erläutert werden.Based on the drawing, in which an embodiment is shown is the invention, further refinements and Improvements of the invention and further advantages be described and explained.

Fig. 5 eine perspektivische Darstellung eines nach dem Verfahren hergestellten Stanzteiles. Fig. 5 is a perspective view of a stamped part produced by the method.
Die in der Fig. 1 gezeigten Stanz-Nibbel-Teile 1 werden mit einer CNC-Maschine nicht vollständig ausgestanzt, sondern sind durch Stege 4 miteinander verbunden. Die Stege 4, die in Fig. 4 vergrößert dargestellt sind, weisen eine rautenförmige Form auf. Zwei der vier Ecken der Stege 4 halten die Stanzteile zusammen, so daß sie zusammenhängend weiterbearbeitet werden können. Die Breite B der Übergangsstellen zwischen Stanzteil 1 und Steg 4 beträgt nur 0,2 bis 0,4 mm. Für 15 cm sind mindestens 3 Stege vorhanden. Die Sollbruchstellen lassen sich derart ausführen, daß die Stanzteile entweder mit der Hand oder mit einem Hilfswerkzeug, z. B. einer Handhebelpresse, nach ihrer Bearbeitung voneinander getrennt werden können.The punching and nibbling parts 1 shown in FIG. 1 are not completely punched out by a CNC machine, but are interconnected by webs 4. The webs 4 , which are shown enlarged in FIG. 4, have a diamond-shaped shape. Two of the four corners of the webs 4 hold the stamped parts together so that they can be processed together. The width B of the transition points between stamped part 1 and web 4 is only 0.2 to 0.4 mm. At least 3 bars are available for 15 cm. The predetermined breaking points can be carried out in such a way that the stamped parts either by hand or with an auxiliary tool, for. B. a hand lever press, can be separated from each other after their processing.
Die Fig. 5 zeigt ein Stanzteil, das nach diesem Verfahren hergestellt werden kann. Es weist zwei Biegelinien 2 für zwei rechtwinklige gekantete Abschnitte 5 und 6 auf. Das Stanzteil ist mit anderen Stanzteilen dieser Art im zusammenhängenden Zustand gekantet und gepulvert worden und erst danach von den benachbarten Teilen getrennt worden. FIG. 5 shows a stamped part, which can be produced by this process. It has two bending lines 2 for two right-angled sections 5 and 6 . The stamped part has been folded and powdered in a connected state with other stamped parts of this type and only then separated from the neighboring parts.
Die Fig. 2 und 3 zeigen zwei Ausführungsformen, bei denen zusätzlich Verstärkungsabschnitte 7 und 8 angeordnet sind. Die Verstärkungsabschnitte sind vorgesehen, damit die Stanz-Nibbel-Teile relativ fest miteinander verbunden sind. Figs. 2 and 3 show two embodiments in which additional reinforcing portions are disposed 7 and 8. The reinforcing sections are provided so that the punching-nibbling parts are relatively firmly connected to one another.
In der in Fig. 2 gezeigten Ausführungsform ist an der Seite ein leistenförmiger Verstärkungsabschnitt 7 angeordnet, der mit den Stanz-Teilen durch Stege 4 verbunden ist.In the embodiment shown in FIG. 2, a strip-shaped reinforcing section 7 is arranged on the side, which is connected to the stamped parts by webs 4 .
Die in Fig. 3 gezeigte Ausführungsform weist einen Verstärkungsabschnitt auf, der zusätzlich aus kammartig angeordnete Steifen 9 besteht, die zwischen den Stanzteilen angeordnet sind.The embodiment shown in FIG. 3 has a reinforcement section which additionally consists of comb-like strips 9 which are arranged between the stamped parts.
