Production of a partially press-hardened metal sheet component

The method comprises transforming raw sheet metal material to a sheet metal mold part, pre-hardening the raw sheet metal material and heating the sheet metal mold part partially in a furnace in such a way that the area to be hardened is covered and is subjected to the press hardening. The non-covere...

Zusammenfassung:	The method comprises transforming raw sheet metal material to a sheet metal mold part, pre-hardening the raw sheet metal material and heating the sheet metal mold part partially in a furnace in such a way that the area to be hardened is covered and is subjected to the press hardening. The non-covered area of the sheet metal mold part is heated in the furnace at above 900[deg] C. The mold formation of the sheet metal mold part corresponds to the vehicle body component. The raw sheet metal material is a coated steel plate. The method comprises transforming raw sheet metal material to a sheet metal mold part, pre-hardening the raw sheet metal material and heating the sheet metal mold part partially in a furnace in such a way that the area to be hardened is covered and is subjected to the press hardening. The non-covered area of the sheet metal mold part is heated in the furnace at above 900[deg] C. The mold formation of the sheet metal mold part corresponds to the vehicle body component. The raw sheet metal material is a coated steel plate. The degree of a thermal shielding of the relevant area is adjusted through the choice of the cover, a covering material, character of the covering material and/or arrangement on the sheet metal mold part. The covering is carried out by two shell molds that are arranged in relevant area on both sides at the sheet metal mold part. The shell mold is formed from a heat-resistant fiber material, a ceramic material, a metallic material or material composite. The shell mold is laid out not directly on the sheet metal mold part. Independent claims are included for: (1) a covering device; and (2) a vehicle body component. Die Erfindung betrifft ein Verfahren zur Herstellung eines partiell pressgehärteten Blechbauteils, insbesondere eines Karosseriebauteils (10), bei dem das Ausgangsblechmaterial zunächst zu einem Blechformteil umgeformt wird und sich dieser Umformung eine Presshärtung anschließt, wozu das Blechformteil partiell in einem Ofen erwärmt wird, derart, dass wenigstens ein nicht zu härtender oder minder zu härtender Bereich (17) abgedeckt wird, und hiernach die Presshärtung erfolgt. Die Erfindung betrifft ferner eine Abdeckeinrichtung zur Abdeckung eines solchen Bereichs (17), sowie eine Fahrzeugkarosserie umfassend ein nach dem erfindungsgemäßen Verfahren und/oder unter Verwendung einer erfindungsgemäßen Abdeckeinrichtung hergestelltes Blechbauteil.
