Stamping parts governor cover includes four stamping process of blanking,drawing,punching and flanging,in order to resolve the problem of using multiple dies in the process of stamping and improve the effi-ciency of stamping production,the stamping process of the governor cover was analyzed from the aspects of drawing blank size,drawing times,pre-flanging punch size,flanging coefficient and flanging limit height.The results show that flangeless cylindrer and flanging can be completed at one time,the 4 stamping processes of blanking,drawing,punching and flanging can be completed by a pair of dies at the same time.The stamping produc-tion scheme of blanking-drawing-punching-flanging composite die is adopted,The mold structure is more complex,which can improve the production efficiency while ensuring the production quality of the governor cover.
