Flexible Roll Forming (FRF) allows the forming of components with a variable cross section along length component. However, process has only limited application in automotive industry due to wrinkling flange which currently prevents high strength steels and limits part shape complexity. This paper presents new technology, Incremental Shape Rolling (ISR), where pre-cut blank is clamped between t...

Hot ring rolling is a highly nonlinear, unsteady-state and asymmetry process which is affected by many parameters. The friction coefficient between the ring ,the driver roll and the idle roll is one of the problems, which has significant effect on the quality of final product. In this study, the effect of these two parameters on hot ring rolling was investigated based on a 3D coupled-thermo mec...

Variable cross-section roll forming is a new process developed on the basis of traditional constant forming. It can produce variable products flexibly and efficiently, which great significance to automobile lightweight. In this paper, rolling section longitudinal beam simulated, finite element model sheet metal established in ABAQUS software, deformation stress distribution are analyzed. conclu...

The outer surface of the tube is worn under interaction between velocity difference and rolling pressure, in process circular into a rectangular tube. In order to predict wear depth, according characteristics roll forming, causes forming are analyzed. finite element model was established based on Archard theory, 40 mm × 27.5 3 SUS304 stainless steel simulated. simulated results were compared wi...
