Progressive Curling Technology for Chip Conveyor Belt Parts

The chip conveyor belt parts consist of progressively curled conveyor plates. Realizing the proper shape using progressive curling is difficult because bending and forming simultaneously are challenging. Therefore, this study aims to obtain the optimized design by performing progressive curling design through forming analysis in advance. The study examines the possibility of encountering sheet metal SM35C defects during progressive curling using forming analysis and reviews the damage value, distributions of the plastic effective strain, and residual effective stress. Moreover, the results set and applied the process number taken from the curling process of the chip conveyor belt parts are optimized by the sheet-metal forming analysis for an actual manufacturing process.
