Description

Technical Field

[0001] The invention belongs to the technical field of rolled bright strip processing and relates to a device for releasing internal stress of rolled bright strips. Background Art

[0002] Bright strips are decorative parts on car windows, which play a role in aesthetics. Since bright strips are set on the outside of the car body, they have higher appearance requirements, need to be bright in appearance, and have uniform thickness and width, so rolling process is often adopted.

[0003] Because the final bright strip has a certain curvature, the rolled bright strip semi-finished product needs to be bent. Due to the varying tensile strength of the rolled bright strip semi-finished product, the internal residual stress within the rolled bright strip semi-finished product is unstable. This leads to significant contour variations after bending, requiring frequent mold adjustments. Existing technologies lack a device structure to relieve this internal stress, leaving significant room for improvement. Summary of the Invention
