AI Technical Summary
Residual stress generated during the manufacturing process of thin-walled, multi-ribbed aluminum alloy machined parts leads to excessive deformation after prolonged storage, and aging treatment cannot be effectively inspected and controlled, affecting assembly quality and efficiency.
A stress release deformation control device for thin-plate multi-ribbed machined parts is adopted, including an integral placement frame and a shape-preserving placement structure. Through the shape-preserving module of key interfaces and the flatness control module of thin-walled parts, the direction of residual stress release of the parts is controlled. Stress release control pressure plate and quick clamping device are used for clamping to ensure that the external dimensions of key installation interfaces meet the requirements.
It effectively controls the direction of residual stress release in parts, reduces deformation after prolonged storage, improves assembly quality and efficiency, and avoids damage to the outer surface quality of parts during subsequent straightening.
