In order to enhance forming performance of magnesium alloy,the performance and drawing process of magnesium alloy were analyzed,so the die's structure of deep drawing for magnesium alloy sheet was optimized.In the die,the resistance loop was used to heat blank holder and so on,the thermocouple was used to control die's temperature,the circulating water was used to cool the die.The structure styles of the resistance loops were designed.At last,some considerations about the design,preparation and use of the die were put forward.
