Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines gehärteten Blechprofils aus einer Platine oder einem Halbzeug, die zum Blechprofil warm umgeformt und gehärtet wird.The The invention relates to a method for producing a hardened sheet metal profile from a board or a semi-finished product, which is transformed into a hot-rolled sheet metal profile and hardened becomes.

Das Warmumformen und Härten im Pressenwerkzeug ist aufgrund der Kombination von Umform- und Vergütungsvorgang in einem Werkzeug eine rationelle Arbeitsweise.The Hot forming and hardening in the press tool is due to the combination of forming and compensation process in a tool a rational way of working.
Hierbei erweist es sich als nachteilig, dass die Warmumformteile beispielsweise nicht mit einem konventionellen Tiefziehvorgang in einem aus einer Matrize, einem Stempel und einem Blechhalter bestehenden Werkzeug hergestellt werden können. Durch den Kontakt mit dem Blechhalter kühlt das Blechprofil bzw. die Platine in diesem Bereich schnell aus, während das Blechprofil im Bereich der Zarge eine höhere Temperatur aufweist. Dies bewirkt, dass das Blechprofil beim Umformen im abgekühlten, und damit nicht mehr so gut umformbaren, Bereich reißt. Um das zu verhindern, sind zusätzliche Vorformoperationen erforderlich. Werden die Blechprofile dagegen ohne Blechhalter, durch reines Formen, hergestellt, ergibt sich eine große Faltenbildung, welche zu Dopplungen im Blechprofil führt bzw. führen kann.in this connection proves to be disadvantageous that the hot-formed parts, for example not with a conventional deep-drawing process in one of a die, made of a stamp and a blank holder existing tool can be. By the contact with the blank holder cools the sheet metal profile or the Board in this area quickly while the sheet metal profile in the area the frame a higher Temperature has. This causes the sheet profile during forming in the cooled, and thus not so good formable, area rips. To that to prevent are additional Preform operations required. Will the sheet metal profiles against it without blank holder, produced by pure forms, results a big Wrinkling, which leads to doublings in the sheet profile or to lead can.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, ein rationelles und ökonomisches Verfahren zur Herstellung von gehärteten Blechprofilen aus einer Platine zu schaffen, bei welchem insbesondere auf aufwändige Vorformoperationen verzichtet werden kann.In front In this background, the invention is based on the object rational and economical Process for producing hardened sheet metal profiles from a Create board, which in particular to elaborate preforming operations can be waived.
Diese Aufgabe wird gelöst mit einem Verfahren gemäß den Merkmalen des Patentanspruchs 1. Die Unteransprüche betreffen besonders zweckmäßige Weiterbildungen der Erfindung.These Task is solved with a method according to the features of the claim 1. The dependent claims relate to particularly expedient developments the invention.
Erfindungsgemäß ist also ein Verfahren zur Herstellung eines gehärteten Blechprofils aus einer Platine oder einem Halbzeug vorgesehen, bei welchem die Platine oder das Halbzeug in einem aus einer Matrize, einem Blechhalter und einem Stempel bestehenden Pressenwerkzeug, insbesondere durch Tiefziehen, zum Blechprofil warm umgeformt und gehärtet wird, wobei vor der Umformung ein Abstand zwischen einer Matrize und einem Blechhalter eingestellt wird, der größer als eine Platinendicke ist. Hierdurch wird ein flächiger Kontakt der auf Härtetemperatur erhitzten Platine mit dem Blechhalter verhindert. Ein ungleichmäßiges Abkühlen des Blechprofils nach dem Stand der Technik findet nicht statt, wodurch das Reißen des Blechprofils während des Umformens aufgrund unterschiedlicher Temperaturen im Bauteil erfolgreich verhindert werden kann. Hierdurch kann auf zusätzlich Vorformoperationen bei der Herstellung von komplexen Blechprofilen verzichtet und die Fertigungskosten und Fertigungszeiten erheblich reduziert werden. Gleichzeitig wird durch den im Abstand angeordneten Blechhalter die Faltenbildung beim Umformen vermindert bzw. verhindert.According to the invention is thus a method for producing a hardened sheet metal profile from a circuit board or a semi-finished product, in which the board or the Semi-finished in one of a die, a sheet holder and a Stamp existing press tool, in particular by deep drawing, is thermoformed and hardened to the sheet profile, wherein prior to forming set a distance between a die and a blank holder that gets bigger than a board thickness is. As a result, a surface contact is the hardening temperature heated board with the sheet holder prevented. An uneven cooling of the Sheet metal profile according to the prior art does not take place, which the tearing of the sheet metal profile during the forming due to different temperatures in the component successfully can be prevented. This can additionally preforming operations at dispenses with the production of complex sheet metal profiles and the manufacturing costs and production times are significantly reduced. At the same time by the spaced sheet holder the wrinkling during Forming reduced or prevented.
Eine besonders zweckmäßige Weiterbildung des vorliegenden Verfahrens wird auch dadurch geschaffen, dass der Abstand während oder/und nach der Umformung derart reduziert wird, dass das Blechprofil zumindest abschnittsweise flächig an dem Blechhalter anliegt. Hierdurch wird gewährleistet, dass sich dass Blechprofil nach erfolgter Umformung gleichmäßig und mit der notwendigen Abkühlgeschwindigkeit abkühlt, so dass das Blechprofil die erforderliche bzw. gewünschte Härte und Festigkeitseigenschaften aufweist. Durch die bessere Wärmeabfuhr unter dem Blechhalter kann die Zykluszeit zur Herstellung des gehärteten Blechprofils reduziert und somit Fertigungskosten gesenkt werden.A particularly expedient development of The present method is also created by the distance while and / or after the forming is reduced such that the sheet metal profile at least in sections, flat rests against the sheet holder. This ensures that the sheet metal profile evenly and after forming with the necessary cooling rate cools, so that the sheet metal profile the required or desired hardness and Having strength properties. Due to the better heat dissipation under the blank holder, the cycle time for the production of the hardened sheet profile reduced and thus manufacturing costs are reduced.
Dabei erweist es sich als besonders vorteilhaft, wenn vor der Umformung ein Abstand eingestellt wird, der zwischen 0,1 mm und 50,0 mm größer als die Platinendicke ist. Dieser Abstand ist erforderlich, um eine Umformung der Platine ohne flächigen Kontakt mit der Matrize zu gewährleisten.there proves to be particularly advantageous if before forming a distance is set that is between 0.1 mm and 50.0 mm larger than the board thickness is. This distance is required to get one Forming the board without surface contact to ensure with the die.
