Granted: 1997-09-20
Abstract: FIELD: plastic metal working, namely die sets for sizing blanks and articles. SUBSTANCE: significant warping of blanks made, for example by casting or forging with annealing, demands restoration of their geometry by sizing. At sizing articles in die sets of press by pieces labor consumption is increased and throughput is lowered. In order to eliminate it yokes are mounted on upper and lower plates of press. In cone openings of said yokes spring-loaded sectorized dies are inserted. Depth of gravures of said dies for placing blanks is less than height of said blanks. Efforts occurring at operation of press due to contact of ends of die gravures and blanks provide simultaneous three-dimensional sizing of two blanks.
