SHAPE BENDING MILL ROLL Russian patent published in 2005 - IPC

FIELD: rolled stock production, possibly manufacture of cold bent rolled shapes.

SUBSTANCE: roll includes arbor with diameter d having flange, shaping members with predetermined rolling diameter D and unit for securing them to arbor. Said unit is arranged at side of mill drive and it includes cylinder-cone locking ring mounted on arbor and three stops equally spaced one form other and secured to arbor by means of bolts. Stops have upper and lower cylindrical surfaces whose diameters are equal respectively (0.7- 0.8)D and d. Lateral surfaces of stops are parallel to roll axis; their end surfaces are normal relative to roll axis. Generatrices of inner cylindrical surfaces of stops turned to shaping members are inclined by angle α = 68 -70° to roll axis and they engage with cone surface of locking ring whose generatrix is inclined by angle α to roll axis.

EFFECT: enhanced quality of bent shapes due to their improved geometry, lowered costs of production process.
