Hot forming line and method for producing a hot formed and press hardened motor vehicle part

Abstract

A hot forming line for producing hot formed and press hardened steel sheet products, includes: a forming device; a heating device having a temperature treatment station, wherein the temperature treatment station includes an upper tool and a lower tool, and at least one temperature treatment source; and exchangeable temperature treatment plates for conductive temperature treatment of a blank or part inserted into the temperature treatment station, wherein the exchangeable temperature treatment plates are constructed for arrangement on the upper tool and/or the lower tool, and the temperature treatment source is constructed for heating or cooling the temperature treatment plates. The temperature treatment station is constructed for treating different regions of the blank or part with different temperatures by conductive contact of the temperature treatment plates with the blank of part.

What is claimed is: 
     
         1 . A temperature treatment station for temperature treatment of sheet metal blanks and/or sheet metal components, said temperature treatment station comprising:
 an upper tool, and a lower tool;   at least one temperature treatment source configured as an electrical resistance heating source; and   temperature treatment plates configured for arrangement on at least one of the upper tool and the lower tool and for conductive temperature treatment of at least one of the sheet metal blanks and sheet metal components, said temperature treatment plates being exchangeable and configured as an electrical resistance themselves and heatable to above 1,000 degree Celsius.   
     
     
         2 . The temperature treatment station of  claim 1 , wherein the temperature treatment plates are configured flat for temperature treatment of a sheet metal blank plate, and wherein a hollow space remains between the temperature treatment plates in a closed state of the temperature treatment station. 
     
     
         3 . The temperature treatment station of  claim 1 , wherein one of the temperature treatment plates is form fittingly coupled with the upper tool and/or another one of the temperature treatment plates is form fittingly coupled with the lower tool. 
     
     
         4 . The temperature treatment station of  claim 1 , wherein one of the temperature treatment plates is form fittingly coupled with the upper tool via bolts and/or another one of the temperature treatment plates is form fittingly coupled with the lower tool via bolts. 
     
     
         5 . The temperature treatment station of  claim 1 , wherein the temperature treatment plates have a coating. 
     
     
         6 . The temperature treatment station of  claim 1 , wherein the coating is a scale resistant coating
