AI Technical Summary
In existing sheet metal forming processes, parts are subject to severe local deformation and high local dislocation density, which leads to decreased material toughness and internal damage. Traditional manual forming is labor-intensive and increases forming resistance.
The vacuum forming method is used to fix the parts on the mold. A closed space is formed by high temperature adhesive, silicone plate and vacuum bag. Vacuum is drawn to make the parts fit the mold surface, reduce local stress, distribute the force evenly and reduce the dislocation density. High temperature adhesive is used to prevent air leakage from the vacuum bag.
This results in uniform stress distribution on parts, reduced dislocation density, improved forming capacity, reduced labor intensity, shorter forming time, and improved forming accuracy.
