METHOD FOR PRODUCING A METALLIC COMPONENT COMPRISING ADJACENT SECTIONS HAVING DIFFERENT MATERIAL PROPERTIES BY MEANS OF PRESS HARDENING

摘要

The invention relates to a method for producing a metallic component (B), whereby adjacent regions (Z1, Z2, Z3) having different material properties can be produced on the metallic component (B) in a simple manner. According to said method, a sheet metal element (E) heated to a forming temperature is shaped in a form tool (1) into an end component (B). The form tool (1) comprises a tempering device for regulating the temperature of at least one of the sections (5,7,16) thereof that comes into contact with the sheet metal element (E) during the forming process. The forming speed is controlled in such a way that the component regions with the desired increased hardness come into contact with the cooled form tool faster than adjacent regions with the desired reduced hardness. The invention is especially suitable for shaping sheet metal elements of different thicknesses that are interconnected with a material fit (tailored blanks).
