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...

one of the great challenges in the processing of materials using equal channel angular pressing (ecap) is the high forming forces required to produce large shear deformation in the material. researchers show that the friction forces between the die and the sample constitute a great part of the total forming forces. recently, ultrasonic vibrations are successfully implemented into the ecap proce...

Abstract Roll forming is a continuous manufacturing process designed for large batch sizes. In order to economically produce roll formed parts with smaller sizes, the setup times have be reduced. During setup, profile defects and especially deformation caused by release of process-inherent residual stresses, also known as end flare, counteracted. However, knowledge regarding creation stresses l...
