Outer panel part manufacturing method for motor vehicle, involves deep-drawing metal sheet that is transformed in deep-drawing tool, where metal sheet and/or deep-drawing tool are heated to predetermined temperature during transformation

摘要

The method involves deep-drawing a metal sheet (12) that is transformed in a deep-drawing tool (16). The metal sheet and/or the deep-drawing tool are locally uniformly heated to a predetermined temperature i.e. 100 degrees Celsius, during transformation. A set of heating devices (22) e.g. induction coils, with the metal sheet is allowed to come into contact with a set of surfaces (24, 26) of upper halves (20) of the tool. The metal sheet and/or the tool are heated in an inhomogeneous manner.
