Abstract
A method for producing a motor vehicle component from a lightweight metal alloy is disclosed including extruding a profile having at least two wall thicknesses that are mutually dissimilar in the cross section, rolling the extruded profile in portions in the extrusion direction. The rollers in the roller spacing thereof are variable. Cutting-to-length the extruded and in portions rolled profile so as to form a semi-finished product, and forming the semi-finished product so as to form the motor vehicle component.
Claims19
A method for producing a motor vehicle component from a lightweight metal alloy, wherein a profile having at least two dissimilar wall thicknesses in the cross section is extruded, comprising:
- providing rollers having variable spacing;
- rolling the extruded profile in portions between the rollers to set, by said rolling, a wall thickness which is smaller than or equal to a smaller wall thickness of the extruded profile;
- cutting the extruded cross section to length and in portions of the rolled profile so as to form a semi-finished product;
- and
- forming the semi-finished product so as to form the motor vehicle component.
A method of producing a motor vehicle component, the method comprising:
- extruding a lightweight metal alloy into a profile having at least two dissimilar wall thicknesses in a cross section of the profile;
- feeding the extruded profile into a variable spacing between rollers, and rolling a portion of the extruded profile between the rollers to set, by said rolling, a wall thickness which is smaller than or equal to a smaller wall thickness of the extruded profile;
- after said rolling, cutting the profile in a portion other than the rolled portion to form a semi-finished product;
- and
- forming the semi-finished product so as to form the motor vehicle component.
