Research on Algorithm of Forming Limit Height in Semi-Ball Bottom Cylindrical Deep Drawing

Abstract:

With physical experiments and numerical simulation about semi-ball bottom cylindrical parts and flat-bottomed cylindrical parts, we got the thinning law about spherical bottom of semi-ball bottom cylindrical parts, and got forming limit height difference of semi-ball bottom cylindrical parts and flat-bottomed cylindrical parts under the same conditions. In accordance with the principle of constant volume, the cylindrical ball height of semi-ball bottom cylindrical parts can be converted to draw from the cylindrical part height of the flat-bottomed cylindrical parts, which introduced a method of calculating the forming limit height of semi-ball bottom cylindrical parts. Through practical examples, this algorithm is feasible.
