摘要：

A finite element simulation model was established on the basis of the cold roll-beating forming principles of the leadscrew to study the relationship among the radius of the rolling wheel, the fillet radius of the rolling wheel, the amount of beating, and the deformation forces. The single and multiple rolling forming processes were obtained through simulation and obtaining of the deformation force varying laws with the radius of the rolling wheel, the fillet radius of the rolling wheel and the amount of beating. Through the orthogonal test, the influence laws of the amount of beating, the rotational speed of the rolling shaft, the thickness of the rolling wheel and the rotational speed of the workpiece on deformation forces were studied. The change trend of the measured forming forces was basically consistent with the simulation results, and the correctness of the finite element simulation model was verified by the experiments which were carried out on the self-designed cold roll-beating forming leadscrew equipment. © 2020, China Mechanical Engineering Magazine Office.
