Embodiment Construction

[0036] In the figures, the same reference numerals are used for the same or similar components, even if a repeated description is omitted for reasons of simplification.

[0037] figure 1 A plan view and a longitudinal sectional view of the sheet metal blank 1 to be heated are shown. For this purpose, the sheet metal blank 1 has two surfaces 2 , 3 , an upper surface 2 and a lower surface 3 .

[0038] Furthermore, the sheet metal blank 1 has a uniform wall thickness 4 over its entire length 5 . However, the sheet metal blanks 1 have different widths 6 from each other, so that the width 6.1 on one side is significantly smaller than the width 6.2 on the opposite side, wherein again in the region of the cutout 7 a resulting width differs therefrom. 6.31 and 6.32 make up the width 6.3. The multiplication of the corresponding wall thickness 4 by the corresponding width 6 then yields the cross-sectional area of ​​the slab in the corresponding longitudinal section. The cross-sectio...

Abstract

In a heating device for conductive heating of a sheet metal blank with varying cross sectional surface, the sheet metal blank constitutes a direct component of an electric circuit, wherein an electrically conductive compensation element is provided which is placed onto a surface of the sheet metal blank, wherein a sum of the cross sectional surface of the sheet metal blank and the cross sectional surface of the compensation element results in a current conducting cross sectional surface.

Description

technical field [0001] The invention relates to a device for conductive heating (konduktiven conduction heating) heating device for metal slabs. Background technique [0002] It is known from the prior art to form motor vehicle components, in particular motor vehicle exterior components or however also structural components of a motor vehicle, from sheet metal blanks. [0003] For this purpose, hot forming and press hardening are carried out precisely in the automotive industry for the production of high-strength or even very high-strength components from hardenable steel alloys. [0004] For hot forming and press hardening, a metal sheet is first heated at least in regions above the austenitizing temperature and then deformed in this state and quenched by rapid cooling in a press tool or in a downstream cooling device. This process is also known as press quenching. [0005] Heating above the austenitizing temperature seems to imply heating to often more than 900° C., ne...
