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.
Claims17
The motor vehicle door made of light metal, comprising a frame plate, wherein a sill reinforcement, a beltline reinforcement, a mirror reinforcement, a lock reinforcement, a hinge reinforcement and optionally a door impact support are coupled to the frame plate, wherein at least half of the aforementioned reinforcement components are produced in each case as separate extruded profile components, wherein each extruded profile component is subsequently three-dimensionally shaped and is coupled to the frame plate and at least two reinforcement components have a wall thickness which is different in the cross section thereof.
The method for producing a motor vehicle door, wherein a frame plate made from a light metal alloy is provided, at least one reinforcement component being coupled thereto, characterized by the following method steps:
- producing an extruded profile from an aluminum alloy, wherein the extruded profile has different wall thicknesses in the longitudinal direction and/or in the transverse direction,
- cutting the extruded profile to length to form individual extruded profile pieces,
- three-dimensional press forming of the extruded profile piece to form a reinforcement component,
- optional stamping and/or perforating of the extruded profile piece and/or the reinforcement component,
- coupling the reinforcement component to the frame plate.
