|
Considering the difficult seal of liquid media and complex installation etc.existing in the traditional hydro-mechanical deep drawing,a new process was proposed,which replaced the original liquid medium with the solid granules to solve these problems.Force analysis in the drawing process reveals that the new technology of solid granulemedium deep drawing can effectively reduce tensile stress in the forming process,and it is helpful to improve material formability.Through the experiment of the LY12M sheet with the self-designed die set,the feasibility of the solid granule medium deep drawing process was verified.The limited deep drawing coefficient can be up to 0.51,superior to the traditional rigidity-die deep drawing process.
