Multi-stage rubber forming eliminates flange wrinkling in aluminum alloy sheet metal production
A multi-stage rubber forming process, incorporating additional cylinders, significantly reduces or eliminates wrinkling in convex flanges made from 2A12 aluminum alloy sheets.
Journal of Advanced Mechanical Design Systems and Manufacturing · 2023
Key Findings
- 01Master-cylinder feed has the greatest theoretical influence on wrinkle reduction, with increased feed leading to smaller wrinkles.
- 02Even with maximum master-cylinder feed, complete wrinkle elimination was not achieved.
- 03Multi-stage rubber forming, by introducing additional forming force from extra cylinders, effectively reduces wrinkling.
- 04Optimal parameters for wrinkle elimination were found to be an extra-cylinder feed of 8 mm and a master-cylinder feed of 34 mm.
Application
Design takeaway
For producing high-quality aluminum alloy convex flanges without wrinkles, consider implementing a multi-stage rubber forming process with supplementary hydraulic cylinders.
How to apply
When designing or troubleshooting the production of flanged metal parts, evaluate the potential benefits of a multi-stage rubber forming approach to mitigate wrinkling issues.
Project actions
- 01When investigating manufacturing defects, consider process modifications rather than just material properties.
- 02Simulation tools can be valuable for understanding complex forming processes and testing new methods before physical prototyping.
