Roller assembly for use as bending tool for roller bending device for bending e.g. ring bending parts, has holders comprising bearing projections positioned between bending rolls, and axles or shafts supported between bending rollers

摘要

The assembly (51) has bending rollers (5, 6, 7) mounted at common holders (8, 12). The bending rollers provided on axles (10, 11) or shafts. The holders comprise bearing projections positioned between the bending rolls. The axles or the shafts are supported between the bending rollers. Width of the bearing projections is larger than width of the bending rollers. Supplementary bearing projections are arranged beside outside the bending rollers in an axial direction toward an outer side of the assembly and receive forces from the bending rollers. An independent claim is also included for a bending device.
