Abstract

Aiming at the problems of poor forming accuracy and severe spring-back of workpiece shapes in flexible spinning technology, the work aims to study the influencing factors of spring-back during the spinning process, analyze the influence laws of different process parameters, and propose relevant measures to improve workpiece accuracy and reduce spring-back. With 5A06 aluminum alloy conical spun components as research objects, the spring-back angle was introduced as an evaluation criterion. Through a combined approach of finite element simulation and experiments, the influence of process parameters on the spring-back of spinning components was analyzed to determine the optimal process parameters and spring-back compensation methods. Based on simulation and experimental analysis, adopting equal circumferential strain, a small feed ratio, and a small pass deformation could effectively suppress the spring-back of the workpiece. The spring-back compensation of adding 3° target deflection angle reduced the spring-back deviation of the main part of the component to -0.21°. By combining the finite element method with process tests, the rebound compensation measures for flexible spinning are summarized, providing effective theoretical guidance for controlling spring-back in flexible spinning components.
