A direct anti-springback method is to offset the expected springback amount through pre-compensation of the Intelligent Wearing
Micro Screws's surface. The design requires:
1. Predicting the direction and magnitude of springback through finite element analysis or empirical data.
2. Reverse correction of the Intelligent Wearing Micro Screws's working surface.
3. Adopting an adjustable Intelligent Wearing Micro Screws structure for easy later correction.
4. Implementing zoned compensation design for complex curved surfaces.
(II) Process Parameter Optimization Design
1. Blankholder Force Control: Properly setting the blankholder force can effectively reduce springback; segmented variable blankholder force technology is commonly used.
2. Drawbead Arrangement: Controlling material flow by optimizing the position, quantity, and shape of drawbeads.
3. Multi-Process Forming: Decomposing complex shapes into multiple progressively formed processes reduces the amount of deformation per step.
4. Local Reinforcement Technology: Setting reinforcing ribs or bulges in areas prone to springback.
(III) Innovative Structural Design of Intelligent Wearing Micro Screws
1. Adjustable Insole Structure: Adjustable inserts are installed in areas of severe springback for easy compensation and correction.
2. Hydroforming Technology: Liquid is used as the force transmission medium to achieve uniform force distribution.
3. Hot-Formed Intelligent Wearing Micro Screws: High-strength steel and other materials are formed using a hot-forming process.
4. Overforming Technology: The design intentionally incorporates a certain angle of "bending" to utilize springback to achieve the target shape.
