Deep pull

The deep drawing machine is hydraulic and mechanical. The former has a slow and even movement speed. As the first choice, the mechanical drawing machine should be used when the drawing rate is small. The calculation of the required force for a deep-drawn magnesium alloy cylinder can be calculated by the following empirical formula: p=πdtRm(D/dk) where p is the pressure and N; D is the diameter of the cylinder, mm, d is the diameter of the punch, mm t is the sheet thickness, mm; Rm is the tensile strength of magnesium at deep drawing temperature, N/mm2; k is the coefficient, 0.8-1.1.
