Abstract
A motor vehicle door and a method for producing the motor vehicle door is disclosed having a frame plate coupled to reinforcement components and at least half of all of the reinforcement components are produced as extruded profiles which are subsequently press-formed three-dimensionally. The extruded profiles have different wall thicknesses.
Claims9
A method for producing a motor vehicle door, comprising:
- providing a motor vehicle door frame plate, wherein the door frame plate is press-formed from a light metal alloy;
- extruding a profile from an aluminum alloy, wherein the extruded profile has different wall thicknesses in a longitudinal direction and/or in a transverse direction;
- cutting the extruded profile at a first length to form individual extruded profile pieces;
- press forming of the extruded profile piece in a three-dimensional manner to form a reinforcement component for reinforcing a region of the motor vehicle door frame plate;
- stamping the reinforcement component;
- perforating the stamped reinforcement component;
- and,
- coupling the at least one reinforcement component to the motor vehicle door frame plate.
