Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Erwärmung von Metallblechen, insbesondere von Stahlblechen zur Warmumformung unter anderem in Kombination mit anschließendem Presshärtevorgang. Dabei wird das Metallblech durch ein Greifer-Erwärmungssystem, über welches die Energieeinleitung erfolgt, erwärmt und in ein Presswerkzeug, bestehend aus einem Unterwerkzeug und einem Oberwerkzeug eingelegt.The The invention relates to a method and a device for heating Metal sheets, in particular of steel sheets for hot forming below other in combination with subsequent press hardening process. In this case, the metal sheet by a gripper-heating system over which the Energy is introduced, heated and in a pressing tool, consisting of a lower tool and an upper tool inserted.
Stand der TechnikState of the art
Metallbleche im Allgemeinen werden kalt oder warm umgeformt. Die unter anderem hier zum Einsatz kommenden borlegierten Stahlbleche werden üblicherweise warm umgeformt und pressgehärtet. Durch diese Vorgehensweise werden die Werte für die Zugfestigkeit und Härte gegenüber den Ursprungswerten deutlich gesteigert.metal sheets generally cold or hot are formed. The among others Boron-alloyed steel sheets used here are customary hot formed and press hardened. By doing so, the values for tensile strength and hardness are compared with those of Origin values significantly increased.

Nachteilig an dieser Vorrichtung ist die starke Erwärmung des Werkzeuges und auch eine starke Erwärmung des Umformraumes. Insbesondere bei Temperaturen bis zu 1000°C wäre der Umformprozess nicht mehr sicher beherrschbar.adversely in this device is the strong heating of the tool and also a strong warming of the forming space. Especially at temperatures up to 1000 ° C would be the forming process no longer controllable.
Ein weiterer Nachteil dieses Erwärmungsverfahrens im Umformraum ist, dass die Hubzahl durch den Erwärmungsvorgang erheblich verschlechtert wird. Die Taktzeit verlängert sich entsprechend der Zeitdauer des Erwärmungsvorganges.One Another disadvantage of this heating process in the forming space is that the number of strokes due to the heating process is significantly deteriorated. The cycle time is extended according to the Duration of the heating process.
Aufgabe und Vorteil der ErfindungTask and advantage of the invention
Der Erfindung liegt die Aufgabe zugrunde, ausgehend vom Stand der Technik, ein Verfahren und eine Vorrichtung zur Erwärmung von Metallblechen, insbesondere von Stahlblechen zur Warmumformung mit anschließendem Presshärtevorgang zu entwickeln, wobei die Erwärmung im Wesentlichen innerhalb einer Pressenanlage erfolgt, und wobei diese Erwärmung keinen nennenswerten Einfluss auf die Hubzahl der Presse hat.Of the Invention is based on the object, starting from the prior art, a method and a device for heating metal sheets, in particular of steel sheets for hot forming with subsequent press hardening process to develop, with the warming essentially takes place within a press plant, and wherein these warming has no appreciable influence on the stroke rate of the press.
Diese Aufgabe wird ausgehend von einem Verfahren nach dem Oberbegriff des Anspruch 1, durch die kennzeichnenden Merkmale des Anspruch 1 und ausgehend von einer Vorrichtung nach dem Oberbegriff des Anspruch 9 durch die kennzeichnenden Merkmale des Anspruch 9 gelöst. In den Unteransprüchen sind vorteilhafte und zweckmäßige Weiterbildungen des erfindungsgemäßen Verfahrens bzw. der erfindungsgemäßen Vorrichtung angegeben.These Task is based on a method according to the preamble of claim 1, characterized by the characterizing features of claim 1 and starting from a device according to the preamble of the claim 9 solved by the characterizing features of claim 9. In the dependent claims are advantageous and expedient developments of the method or the device according to the invention specified.
Der Erfindung liegt der Gedanke zugrunde die Metallbleche nicht wir bisher bekannt in einem Ofen vor der Presse oder im Umformraum der Presse, sondern während des Einlegens eines Bleches in die Umformstufe zu Erwärmen. Die Dauer des Transportes wird somit genutzt für die Erwärmung der Bleche. Die Transportvorrichtung wirkt gleichzeitig als Erwärmungsvorrichtung. Das kalte Blech wird dabei außerhalb des Pressenraumes von der Transport-/Erwärmungsvorrichtung aufgenommen, während des Einlegetransportes auf eine Solltemperatur erwärmt und in erwärmtem Zustand im Umformwerkzeug, vorzugsweise auf der Umformgeometrie des Unterwerkzeuges, abgelegt. Die Solltemperatur beträgt 920°C bis 1000°C, aber auch andere Temperaturbereiche sind realisierbar.Of the Invention, the idea is based on the metal sheets not us previously known in an oven in front of the press or in the forming of the Press, but during the insertion of a sheet in the forming stage to heat. The Duration of transport is thus used for the heating of the sheets. The transport device acts as a heating device at the same time. The cold sheet is outside the press room taken by the transport / warming device, while the Einletransportes heated to a desired temperature and in heated Condition in the forming tool, preferably on the forming geometry of the lower tool, filed. The target temperature is 920 ° C to 1000 ° C, but also other temperature ranges can be realized.
Die Erwärmung der Metallbleche erfolgt elektrisch, vorzugsweise konduktiv, aber auch andere Erwärmungsverfahren, wie beispielsweise induktive Erwärmung sind möglich. Als Option sieht die Erfindung weiterhin vor, dass sich im Werkzeug bzw. im Umformraum stationäre Erwärmungsvorrichtungen befinden, die zusätzlich eine Erwärmung des Bleches vor der Umformung herbeiführen.The warming the metal sheets are electrical, preferably conductive, but also other heating methods, such as inductive heating are possible. As an option, the invention further provides that in the tool or stationary in the forming space Heating devices are located, the additional a warming of the sheet before forming.
