Abstract
Lead-screw cold roll-beating is a new type of green near-shape plastic forming technology. The deformation force is of great importance, which not only can affect the strain & stress of the material but can provide important base for equipment design, verifying tool strength and making reasonable process. This paper focuses on preliminary study of deformation force based on simulation. Firstly, the principle of lead screw cold roll-beating is simply introduced, then the FEM mode in ABAQUS is built, then the normal stress, and tangential stress simulation of lead screw cold roll-beating is carried out, finally changes of the deformation force and its component-force to time are obtained, which can provide good basis for further study.
