Abstract:
A Ring bending machine for pipes and profile rods made of metal, comprising:a) two supporting shafts supported in a spaced relation to each other in a carrier plate and operatively associated with means for rotatably driving said two supporting shafts,b) a pressing shaft arranged perpendicularly with respect to the spacing of said two supporting shafts and in an adjustable manner,c) a slender cover housing for covering said carrier plate, said pressing and supporting shafts and said driving means, each of said supporting shafts and pressing shaft extending through said cover housing and exterior thereof,d) a bending roller provided on each of said supporting shafts and pressing shaft, said bending roller adapted to form a desired profile and bending plane in the pipe or rod to be bent,e) a supplementary frame positioned exterior of said cover housing and attached to said carrier plate by means for attaching said supplementary frame to said carrier plate,f) said supplemental frame comprising first and second carriages perpendicularly displaceable with respect to each other, at least one of said first and second carriages provided with a pressure roller for laterally guiding the pipe or rod to be bent in spaced relation to said bending roller,g) whereby displacement of said first and said second carriages perpendicularly to each other in said supplementary frame will reposition said pressure roller on said carriages and provide selective adjustment of the bending radius and the helical gradient relative to the bending plane of a rod or pipe to be bent.
