Problems solved by technology

Due to the difficulty in partially heating due to locally generated hot spots, the geometry of the components is usually size-limiting
Active regulation of the thermal expansion of the component or the distribution of heat within the component is currently not possible with prior art methods

Embodiment Construction

[0045] figure 1 A perspective view is shown of a metal part 100 with electrodes ( 14 , 15 ) arranged on two mutually opposite narrow sides ( 10 , 11 ). In this case, the structural side 25 of the electrodes ( 14 , 15 ) is arranged over the entire length 23 of the metal part 100 in the middle with respect to the thickness 16 of the metal part 100 . The contact surfaces (21, 22) formed between the electrodes (14, 15) and the side surfaces of the narrow sides (10, 11) facing each other are narrow, or have a small width, which serves as the metal part 100 The thickness of 16.

[0046] Thus, the electrodes (14, 15) are not arranged on the entire thickness 16 of the metal part 100, but only in the middle and on a part at the side surfaces (10, 11) of the metal part 100, between the two electrodes (14, 11). 15) After energization, the generated current 18 is directed horizontally and centrally through the metal part 100 . Figure 2a The current 18 is shown in the horizontal direct...

Abstract

The present invention provides a method for conducting a heating metal part to reduce the cost of thick metal parts in the batch production process and improve the conduction heating of the thickness of the metal parts.

Description

technical field [0001] The invention relates to a method for electrically conductive heating of sheet-shaped metal parts for thermoforming or as an initial stage of thermoforming. [0002] Furthermore, the invention also relates to an electrically conductively heated sheet-shaped metal part and a device for electrically conductively heating a sheet-shaped metal part. [0003] Usually, sheet-shaped metal parts, for example sheet metal, are formed by shape hardening or thermoforming. Here, the component is heated to a set forming temperature and subsequently deformed into the desired shape, for example by means of pressure. In such thermocompression forming processes of sheet-like components, the forming temperature prior to forming is the main criterion for achieving the maximum degree of deformation and the forming force required for this. At lower temperatures, demanding or complex geometries cannot usually be machined due to cracks due to reduced formability. Furthermore,...
