FIELD: plastic metal working, namely manufacture of bent shapes with high degree of readiness. SUBSTANCE: stand of shape bending mill includes housing in which drive shafts are mounted. Profiling rolls and shaped pressure discs are mounted on said shafts. Two mutually joined pressure plates are mounted in rails of housing with possibility of reciprocation motion along rolling axis. Stand is provided with perforating mechanism in the form of spring-loaded punches and dies coaxial to them. Punches are mounted with possibility of vertical motion in upper pressure plate and they engage with upper shaped pressure discs. Dies are mounted on lower pressure plate. Mechanism for providing working motion of pressure plates is in the form of involute toothed rack secured to lower pressure plate and toothed sectors engaging with said rack and provided on disc rigidly mounted on lower drive shaft.
