in this paper the drawing technology of high rectangular case is analysed, the blank dimensions and figures of rectangular case were calculated, thedrawing numbers and the process dimensions were determined, and the die structure of drawing die were designed.

Study on fracture prediction of deep drawing for square box;

Effect of local convex cylindrical blank-hold surface on square box part forming

Introduced drawing craft s computational method of the high cone-shape box body, through reasonable drawing gap, and using approopriate lubricant and lubrication method, the component was drawing with ideal surface quality.

Design of curling die for flanged square box

Although available methods of blank expanding are useful for flat and equal-height shallow box workpiece,they are unsuitable methods to calculate the expanding blank of flat and height unequal box.
