Method for manufacturing motor vehicle structural component from extruded profile
A recently granted patent (Publication Number: US11999413B2) discloses a method for manufacturing motor vehicle structural components using extruded multichamber hollow profiles. The method involves forming an extruded profile with precursor hollow chambers separated by inner walls, where at least one outer wall has a non-linear course. During the forming process, the non-linear course region of the outer wall is straightened to match the cross-section of the final structural component, while the inner wall remains unchanged.
The method includes steps such as forming the extruded profile in a split pressing tool, where the cross-section of the precursor hollow chambers is modified using forming tools or mandrels. Both compression and expansion processes can be carried out in the same pressing stroke to achieve the desired shape. Additionally, the method allows for adjustments in the width and height of the hollow chambers, resulting in structural components with varying dimensions compared to the precursor hollow chambers. Overall, this innovative method offers a precise and efficient way to manufacture motor vehicle structural components with complex geometries using extruded multichamber hollow profiles.
