Process Parameter Determination of AZ31B Sheet Forming under Mechanical Press

At present, most studies on magnesium alloy sheet forming were carried under hydraulic press. In this paper, differential temperature forming of AZ31B magnesium alloy sheet under the J23-63 mechanical press were carried out. Through an orthogonal test about studying the influence of process parameters on AZ31B magnesium alloy sheet drawing, some conclusions were drawn, which are: the influence of drawing temperature on sheet forming is the biggest, then the drawing die clearance, and lubricant respectively; the optimal process parameters combination is drawing temperature of 310°C, 1.10t die clearance, and 8mm die radius in this test.
