Drawing is used to mold into a plate of 10 steel rough openings for the hollow parts stamping method, using drawing process can be made tube, ladder-shaped pieces, spherical, cone-shaped, parabolic shape, or other irregular shape and thin Wall components. Based on a ladder-shaped cylinder of the drawing process, that ladder tube drawing of the method of calculation. This method is determined by the drawing process, drawing on many occasions to ensure that the process of drawing the shape is not pulled off the transition and eventually pulled out of qualified workpiece. Here on the blanking stretch, repeatedly drawing, shaping, trimming, and other sets of mold. With the method of calculating sure deep drawing technology, make the mold design, processing precision and complexity continuously improve, mold manufacturing continuously shortening period.
