摘要
The invention relates to a tool for hot-tanning and/or press hardening of a sheet metal material, this tool having a plurality of cooling devices through which a coolant can flow, in order thus to be able to actively cool at least regions of the effective tool surfaces which come into contact with the sheet metal material. According to the invention, at least one cooling device comprises a shell element having an effective tool surface, wherein this shell element has, on its rear side facing away from the effective tool surface, a plurality of separate cooling chambers, through which a coolant can flow, and arranged in each of these cooling chambers is at least one flow guiding element for the coolant. The invention also relates to a method for producing such a cooling device for this tool.
