By analyzing the structural characteristics of large flange,two opposite forming schemes were developed.The forming process was developed and the corresponding die was designed ac-cording to the two forming schemes.After the actual production verification,the two schemes could form the parts that meet the requirements,the advantages,disadvantages,and application scope of the two forming methods were determined by comparing the states of the two forming schemes after forming the large flange,which provided certain references for the die design of such parts.
