Deformation Characteristics of the Sheet Metal in the Roll Gap for the Continuous Roll Forming Process

Abstract:

Article Preview

Continuous Roll Forming process (CRFP) is a newly developed technique applied to form 3D surface part with various transverse and longitudinal curvatures. In CRFP, the sheet metal is non-uniformly compressed in the roll gap between the upper and lower bendable rolls. The two bendable rolls rotate in opposite directions, and the sheet metal is bitten into the roll gap continuously. At the present, the deformation characteristics of the sheet metal in the deformation zoon (sheet metal between the upper and lower bendable roll) is discussed. The friction force in CRFP can be calculated according to the Coulomb friction law.
