Study on the Optimization of Spinning Process Parameters of Multi-wedge Pulley
Aiming at the problems of poor forming quality and low life in the spinning process of multi-wedge pulley,Dong'an 513 engine multi-wedge pulley was taken as the research object.Based on the Deform platform,the forming process of cold rolled steel sheet 08A1 multi-wedge pulley was numerically simulated.The spinning process parameters were selected to determine its design variables.The effects of spindle speed,feed speed and radius of the roller on the equivalent stress and forming load of the workpiece were ana-lyzed.Based on Design-Expert software,the design variables of spinning process were optimized by multi-objective genetic optimization algorithm,and the reliability of finite element simulation was verified through experiments.After optimization,the equivalent stress of the formed pulley is reduced by 39 MPa,and the forming load on the spinning wheel is reduced by 10.64％.
