Stamping Process Analysis and Composite Die Design for Governor Cover
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.
