Impact Reinforcement Bead Layout for Compact Roll Stamping

The patent divides the component into multiple sections along its longitudinal direction, each with different cross-sectional shapes. The roll forming device applies different rolling forces and patterns to each section, allowing complex shape changes without requiring a large stamping roll diameter. This segmentation enables localized shape control while maintaining a compact device footprint.

The patent applies localized rolling forces to specific regions of the component during the forming process. By controlling the position, magnitude, and duration of rolling forces applied to different sections, the device can create varied cross-sectional shapes along the longitudinal direction without needing a uniformly large stamping roll, thus reducing overall device size while maintaining component rigidity.

The patent employs a dynamic rolling process where the rolling forces are applied progressively along the longitudinal direction of the component. The rolling forces can be adjusted in magnitude and position during the forming process, allowing gradual shape changes rather than requiring a single high-force pressing operation. This dynamic approach reduces the peak press capacity needed while achieving complex shapes.

The roll forming device applies periodic rolling forces to different sections of the component as it passes through the forming zone. This periodic action allows the material to be gradually shaped through multiple small deformations rather than one large deformation, reducing the required press capacity while achieving the desired complex shape.

The patent enhances the conventional roll stamping device with additional rolling elements and control mechanisms that enable it to perform both traditional uniform rolling and specialized localized rolling operations. This multi-functionality allows the same device to manufacture both simple elongated components and complex components with varying cross-sectional shapes along the longitudinal direction, maintaining manufacturing efficiency while increasing adaptability.

The patent introduces variable parameters into the roll stamping process, including variable rolling force magnitude, variable rolling position along the longitudinal direction, and variable rolling speed. By dynamically adjusting these parameters during the forming process, the device can accommodate different shape requirements while maintaining continuous production and high manufacturing efficiency.
