AI Technical Summary
Existing high-neck flange production lines suffer from problems such as large rolling deformation, high forming difficulty, low production efficiency, unreasonable metal distribution, and high scrap rate.
The optimized high-neck flange production system, including forming dies and mill rolls, optimizes the billet shape through forming grooves, positioning protrusions, and arc-shaped surface structures. Combined with the size differences between the special pre-punch and final punch, the rolling process is optimized to achieve single-pass rolling forming.
It improves the production efficiency of high-neck flanges, reduces scrap rate, lowers labor costs, ensures that the billet is free of folds and dents during rolling, and achieves efficient billet shape control.
