SHAPING APPARATUS Russian patent published in 2006 - IPC B21D22/02 B21D37/08 

FIELD: plastic working of metals, possibly shaping articles of sheet materials.

SUBSTANCE: apparatus includes punch, die and shaping chamber with walls in the form of movable sections. Bands for sensing lateral efforts are joined with said walls through intermediate members. Leverage mechanisms with periodic-action drive units are arranged between movable sections of walls and bands. Punch and die are in the form of bases and groups of shaping members. Each shaping member is provided with individual periodic-action drive unit with normalized movement. Shaping members have surface extending from end to side of outlet link of individual drive unit and touching lateral surfaces of adjacent shaping members. Individual drive units provide periodical setting of contour of die and punch. Peripheral shaping members are adjacent to shaping chamber walls. At shaping strokes periodic-action drive units of leverage mechanisms provide squeezing of groups of shaping members of die and punch by means of movable sections of walls.

EFFECT: enlarged manufacturing possibilities of apparatus.
