METHOD FOR ROLLING ARTICLES WITH PREDETERMINED CURVATURE Russian patent published in 1998 - IPC

FIELD: plastic metal working, namely, manufacture of flat articles with predetermined curvature such as discs. SUBSTANCE: method comprises steps of reducing blank in rolls with cone barrels mounted in such a way that axes of barrel cones crosses at side of small bases of cones; checking curvature of article at roll outlet and correcting it. Novelty is rolling heated blank. Curvature correction is realized due to temperature change according to admissible heating range of blank material. Relation between heating temperature, mean rate of article at roll outlet, width of article, difference of rates of lateral edges of article and objective curvature radius is mathematically normalized. EFFECT: enhanced efficiency. 3 dwg
