Abstract：

The deep drawing of Ti-6Al-4V high strength titanium alloy sheet with thickness of 0.8 mm under different heating temperatures and process conditions was studied by heating in the die, and the influences of different factors on deep drawing of Ti-6Al-4V high strength titanium alloy sheet were discussed. The results show that the temperature is the key factor affecting the deep drawing of Ti-6Al-4V high strength titanium alloy sheet. However, with the increasing of temperature, the drawing performance of material improves. At 800 ℃, the limiting drawing ratio reaches the maximum value which is 45.86% higher than that at the critical drawing temperature of 300 ℃, and the limiting drawing size increases by 45.45%. Furthermore, with the increasing of temperature, the thinning rate of drawing parts decreases, and the distribution of thickness becomes more uniform. In addition, the deep drawing of Ti-6Al-4V high strength titanium alloy sheet is also affected by the changes of blank holder force, lubrication conditions and stamping speed.
