| Abstract: | The test equipment for measuring frictional factors of exterior panel dies and constraint resistances of drawn ribs are designed.Frictional factors of three sets of dies made of different materials as well as four samples of dif-ferent ma terials are measured with the designed equipment under two different conditions of dry friction and with special stamp ing cleaning and rust-proof oil respectively.Dies are made according to shapes and dimensions of three types of drawn ribs used by the manufacturer,and drawing constraint resistances are measured and the measured constraint resis-tances of the three drawn ribs are given.In the end,the measured results are analyzed combined with manufacturing prac-tice. |
