Abstract：
|
|
Flywheel panel is a part of large size and variable wall thickness.If the traditional process,such as cutting and weld-assembling is used,it demands more procedures,takes longer period and costs more.This research adopted a new stamping-forging process.The forming process and key mold dimensions were optimized utilizing DEFORM-2D.In order to shape the inner fillet of R5mm,a forming process with two-step was designed.A drawing-punch with bigger fillet drew the billet and an upsetting-punch compressed the wall first,and then the drawing-punch was replaced by another one which had a fillet of R5mm and the wall was compressed until reaching the size requirements.The optimized simulated results were very well,which could provide a certain reference evidence to the practical industrial production.
