TOOL OF ROLL-FORMING MACHINE Russian patent published in 2009 - IPC B21D5/06 

FIELD: metallurgy.

SUBSTANCE: invention concerns mechanical forming operation of sheet metal, particularly to manufacturing of joist web by forming in rolls. Tool of roll-forming machine contains generating gauge top and bottom rolls. Each roll consists of disk-shaped forming elements at least one remote element implemented with ability of installation on shaft from side of its sides. Each remote element is implemented in the form of bracket of "П"-shaped form maximum limit of size of which do not exceed diametre of adjoining disk-shaped forming elements and width of forming elements and width provides changing of gauge of rollers. Located nearby on shaft brackets are installed with angular deflection relative to each other. Bracket can be implemented with opening for location piece and with faces at ends.

EFFECT: increasing number of manufactured profiled sizes, improving profiles, reduction of manhours and time reduction for adjustment.
