Abstract
The novel concept of macro-structuring deep drawing tools is used here for cryogenic forming of AA6014 in order to improve formability. In addition to known advantages of macro-structuring in tooling like friction force reduction, heat flux can also be directly influenced. This enables cryogenic sheet metal forming without active cooling of the tools. The improved formability and increased strength of aluminium alloys, which is attributed to the effects in the FCC crystal structure at cryogenic temperature, are utilised for increasing the drawing depth. Successful process routes, boundary conditions and design rules are demonstrated and influencings effects are discussed.
