冷滚打成形中滚打深度与回弹规律的仿真
Simulation on Depths of Roll-beating and Springback Rules of Cold Roll-beating Forming
摘要
Abstract
In order to effectively control the effects of springback on formed part precisions,the relation between deformation and springback was studied.According to basic principles of cold roll-beating,a finite element dynamic simulation model was established by ABAQUS software,through simulations forming gullet section deformation laws and springbacks under of different roll-beating depths wre obtained in tangential direction,axial direction and radial direction.Because inner forces of workpiece in results of dynamic simulation were at unbalance states,the springbacks could not be di-rectly solved,so a static simulation model was established based on results of dynamic simulations, and the depths of different roll-beatings of forming gullet section springback rules in tangential direc-tion,axial direction and radial direction were determined by static analysis.Cold roll-beating experi-ments were carried out by using refit experimental equipment and workpiece profile shapes were obtained, compared with simulation results under the same processing conditions,and the results of simulation were validated,thus it provides references to effectively control the springback influences on forming precisions.关键词
