Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines gehärteten Blechprofils aus einer gegebenenfalls vorgeformten Platine. Der Begriff Platine wird nachfolgend einheitlich sowohl für eine ebene Stahlblechplatine als auch für ein bereits vorgeformtes Halbzeug verwendet.The invention relates to a method for producing a hardened sheet metal profile from an optionally preformed board. The term board is subsequently uniform for both a flat sheet steel plate as also used for an already preformed semi-finished product.
Durch die DE 24 52 486 A1 zählt ein Verfahren zur Herstellung eines gehärteten Blechprofils aus einer Platine in einem Presshärtverfahren zum Stand der Technik. Hierbei wird eine aus einem härtbaren Stahl bestehende Platine auf Härtetemperatur erhitzt, dann in einem Pressenwerkzeug warm umgeformt und anschließend ausgehärtetet, während das Blechprofil im Pressenwerkzeug verbleibt. Da das Blechprofil bei der im Zuge des Härtungsvorgangs vorgenommene Kühlung im Pressenwerkzeug eingespannt ist, erhält man ein Produkt mit guter Maßhaltigkeit.From DE 24 52 486 A1 a process for the production of a cured one counts Sheet profile from a board in a Presshärtverfahren for State of the art. Here, one made of a hardenable steel Board heated to hardening temperature, then warm in a press tool deformed and then cured, while the sheet metal profile in the Press tool remains. As the sheet metal profile in the course of the curing process made cooling in the press tool clamped is, you get a product with good dimensional stability.
Das Warmumformen und Härten im Pressenwerkzeug ist aufgrund der Kombination von Umform- und Vergütungsvorgang in einem Werkzeug eine rationelle Arbeitsweise. The hot forming and curing in the press tool is due to the combination of forming and tempering process in a tool rational way of working.
Im Rahmen der WO 99/07492 ist vorgesehen, das vorbeschriebene Presshärtverfahren zu modifizieren und im Pressenwerkzeug die randseitigen Bereiche von vorgefertigten Löchern abzubiegen, so dass Kragen entstehen. Das Abbiegen der Löcher geschieht im Pressenwerkzeug vor dem Härten. Die Öffnungen im Blechprofil sollen als Durchführungslöcher für Befestigungsschrauben dienen. Im Stand der Technik ist es auch üblich, solche fachterminologisch als Durchzüge bezeichnete Öffnungen als Referenzlöcher bzw. Aufnahmen für die positionsgenaue Ausrichtung des Blechprofils in Folgeprozessen zu nutzen. Des Weiteren dienen sie als Montagefreigänge oder als Versteifungsmaßnahme.In the context of WO 99/07492 is provided, the above-described Presshärtverfahren to modify and in the press tool, the marginal areas Turn off prefabricated holes so that collars emerge. The bending of the holes happens in the press tool before hardening. The openings in the sheet metal profile are intended as feedthrough holes for fastening screws serve. In the prior art it is also common to such technically designated as Durchzüge openings as reference holes or recordings for the positionally accurate alignment of the sheet metal profile to use in subsequent processes. Furthermore, they serve as assembly releases or as a stiffening measure.
Das Ausformen der Durchzüge im Pressenwerkzeug bringt jedoch einen vergleichsweise großen Werkzeugverschleiss mit sich. Auch ist nur eine begrenzte Umformung des Kragens möglich. Nachteilig wirken sich zudem gegenüber dem konventionellen Kaltumformen die höheren Fertigungskosten aus.However, the molding of the passages in the press tool brings a comparatively large tool wear with it. Also is only a limited Forming of the collar possible. Disadvantage also have opposite the conventional cold forming the higher production costs out.
Der Erfindung liegt ausgehend vom Stand der Technik die Aufgabe zugrunde, ein Verfahren zur Herstellung von gehärteten Blechprofilen ökonomischer und rationeller zu gestalten.The invention is based on the prior art, the task underlying, a method for producing hardened sheet metal profiles economical and to make it more efficient.
Erfindungsgemäß wird diese Aufgabe durch ein Verfahren gemäß Patentanspruch 1 gelöst.According to the invention this object is achieved by a method according to claim 1 solved.
Die Formgebung eines Durchzugs erfolgt an der Platine außerhalb des Vergütungsprozesses. Wie bereits erwähnt, kann es sich bei der Platine auch um einen Vorformling bzw. ein Halbzeug handeln. Nachdem der Durchzug mit seinem vorstehenden Kragen erstellt ist, wird die Platine erwärmt und in einem Pressenwerkzeug zum Blechprofil warm umgeformt. Hierbei erfolgt eine endformgebende Kalibrierung des Durchzugs. Anschließend wird das Blechprofil noch im Pressenwerkzeug gehärtet. The shaping of a draft occurs on the board outside the tempering process. As already mentioned, it can be with the board as well to act a preform or a semi-finished product. After the passage created with its protruding collar, the board is heated and in a press tool hot formed into a sheet metal profile. This takes place a final shaping calibration of the draft. Subsequently, the Sheet metal profile still hardened in the press tool.
Die Platine wird mit einem oder mehreren Durchzügen versehen. Diese können von verschiedenartiger Form sein, beispielsweise rund oder oval.The board is provided with one or more passages. these can be of various shape, for example, round or oval.
Kernpunkt bildet die Maßnahme, im Vergütungsprozess lediglich noch ein Kalibrieren des Durchzugs auf Endmaß vorzunehmen. Diese Maßnahme stellt sicher, dass der Durchzug mit der erforderlichen Genauigkeit als Referenzpunkt für nachgeschaltete Fertigungsoperationen am Blechprofil fungieren kann. Hierdurch kann auch der Werkzeugverschleiss reduziert und die Fertigungskosten gesenkt werden. Die Vorgehensweise ist verfahrenstechnisch einfach, kostengünstig und rationell.The focus is on the measure, in the compensation process only one Calibrate the draft to final dimension. This measure Make sure that the draft with the required accuracy as a reference point for downstream manufacturing operations on the sheet profile can. This can also reduce the tool wear and the Production costs are lowered. The procedure is procedural simple, inexpensive and efficient.
Als besonders vorteilhaft ist herauszuheben, dass durch das Kalibrieren im Pressenwerkzeug die Platine im Pressenwerkzeug exakt ausgerichtet wird. Infolge dessen kann ein Blechprofil mit hoher Maßgenauigkeit abgepresst werden. Dies ist besonders für die nachgeschalteten Fertigungsprozesse von Vorteil.It is particularly advantageous to emphasize that by calibrating in Pressing the board exactly aligned in the press tool. As a result, a sheet metal profile can be pressed with high dimensional accuracy become. This is especially true for the downstream manufacturing processes advantageous.
