Study on the deformation mode of conventional spinning of plates

The deformation mechanism of conventional spinning is studied in this paper through experiment and analysis. Three types of roller trace have been app lied: straight line, concave curve and convex curve. As a result, all exper iments have indicated that the deformation mode of conventional spinning of plates is quite different from that of the drawing process, but quite simi lar to that of shear spinning. Furthermore, when the original blank is a pl ate the deformation in the first pass has a decisive effect on the wall thi ckness distribution of the product of spinning.
