LIGHT-DUTY SHAPE BENDING MILL Russian patent published in 1999 - IPC

FIELD: equipment for plastic metal working, possibly manufacture of bent bars. SUBSTANCE: shape bending light-duty mill includes common monolithic housing with cylindrical turnings for mounting in bearings upper and lower working shafts. Bearing assemblies of upper shafts are arranged in eccentric sleeves. Radial adjusting mechanism is in the form of worm gear cut on cylindrical sleeve and joined with worm screw arranged in cylindrical turning of housing. In monolithic housing between pairs of cylindrical turnings there are vertical grooves in which cartridges with vertical rollers are placed. It provides mutual alignment of upper and lower working shafts (spindles). EFFECT: enhanced accuracy of profiling, reduced period of tuning mill at rolling, increased rigidity of spindles and vertical rollers, lowered length of mill and weight of equipment, reduced labour consumption for making such equipment due to significantly decreased number of heavy and labour-intensive parts, enlarged manufacturing possibilities of mill due to changing level position of vertical rollers in wide range. 3 cl, 6 dwg
