FIELD: technological processes.
SUBSTANCE: from initial cylindrical stock semi-finished product is formed by means of hot die forging in two stages. In preliminary stage by means of settling in transitions stock dimensions are changed with reduction of height and increase of diametrical dimensions. In final stage cup walls are formed as well as bottom part. Settling is performed in convex and concave strikers with formation of concave and convex conical surfaces on the opposite side of settled stock. Stock is shifted prior to every subsequent transition of settling with concave side onto surface of concave striker. Dimensions of initial cylindrical stock, settled stock prior to corresponding transition of settling and after are selected with account of semi-finished product dimensions based on available ratios. Produced semi-finished product is exposed to thermal and mechanical treatment.
EFFECT: satisfactory working of the whole volume of stock and optimal properties of finished products.
