- The curved surface rolling forming technology based on uneven roll gap can realize the rolling of doubly-curved surfaces through two arc-shaped variable cross-section rollers;
- The rolling technology of 3D curved parts based on arc-shaped rollers can realize flexible rapid forming of doubly-curved surfaces with different specifications through small changes in rolling reduction;
- For the rolling technology of 3D curved parts based on arc-shaped rollers, the maximum rolling reduction determines the degree of the longitudinal bending deformation of the formed curved parts. It is necessary to ensure that the minimum rolling reduction is greater than zero to obtain better shape accuracy of the formed curved parts.
