摘要: The formation of the gear drum clutch involves bulk and sheet forming, filling tooth is a key difficulty during forming process. In this study, four extrusion processes with various ratios preform shape were developed, they simulated using AFDEX software for examining how influenced forming. Various tooth-filling results obtained by controlling ratio die cavity in each A comparison deformation, material flow, mean stress state among revealed that was main determinant local flowing material, it used to improve degree filling. optimal result two-step process an appropriate shape.
