Abstract

Изобретение относитс  к области обработки металлов давлением и позвол ет повысить качество готовых изделий за счет управлени  пластическим раст жением центральной части листовой заготовки 1 в процессе выт жки с торможением ее фланцевой части. Фланец листовой заготовки 1 помещают на прижим, содержащий перет жной порог 2 и полукруглое тормозное ребро 3. При выт жке фланец заготовки 1 изгибаетс  на пороге по R The invention relates to the field of metal forming and improves the quality of finished products by controlling the plastic stretching of the central part of the sheet 1 in the stretching process with braking its flange part. The flange of the sheet blank 1 is placed on the clamp containing the overflow threshold 2 and the semicircular braking rib 3. When stretching, the flange of the blank 1 is bent at the threshold along R
