METHOD FOR MAKING SHAPED ARTICLES Russian patent published in 1999 - IPC

FIELD: machine engineering, namely plastic metal working. SUBSTANCE: in order to enhance accuracy of articles, to eliminate camber of cut blank and its nonplaneness, metallic sheet is fed in automatic mode to die set for subsequent cutting at simultaneously molding article. Cutting is realized in long-period mode beginning from intermittent notching of sheet until finally cutting off blank. Upper shaped metallic blade and lower stationary blade are used for cutting operation. Spring-loaded metallic shaped die and upper shaped metallic blade both following contour of article are used for molding. Then article is knocked out by means of next automatically fed metallic sheet. EFFECT: enhanced quality of articles. 4 dwg, 2 ex
