  • after using dom die, this sheet pressed from a variation condition of size, of die holder power,of rpm speed, accordingly the kind of material, the conditionof deformation movement between both sheets is analyzed, is investigated in the Press machine. even if the change quantity which formed raises a blank holder pressure, the change quantity which is special is not visible from the segment where there is not a bead, the segment where there is a bead to the other side does change quantity schedule to initially and the features of press holding power which the change quantity diminishes is showed consequently from pressurization change quantity it is visible but until a rupture territory from the rpm, it goes but the features where the change quantity does not change a lot is observationd, from the CR2-sheet the quality comes out though well but a possibility of getting a result under same conditions of AL-sheet does not become the formation which stands is. It is like that though press-die which uses the drawing-sheet it exchanges the sheets, when AL-sheet with doing, the conclusion for maintain which have a formation sincerity healthy characteristic is same with afterwords.
