Patent ID: 7024905

Claim:
A pipe bending system, for bending pipes having a pipe outer circumference, comprising: a pair of bending assemblies, the bending assemblies located at fixable relative positions, each bending assembly having: a substantially circular central hub having a hub top, a hub outer circumference, and a hub flange at the hub outer circumference, a vertical central shaft is fixed to the hub and is located centrally thereon, the hub further having a fixed gear mounted on the hub top, the fixed gear having fixed gear teeth, a roller assembly, including a roller arm attached at one end to the central shaft for rotatable movement thereon, a roller mounted to the roller arm outwardly of the roller circumference, the roller having a roller flange opposed from the outer circumference for accommodating a pipe between the roller flange and the hub flange, and a motor, mounted on the roller assembly, the motor driving a pinion having pinion teeth in mesh with the gear teeth, for moving the roller assembly angularly around the hub while the roller flange and hub flange remain in contact with a pipe inserted therebetween, for bending the pipe to follow the outer circumference as the roller arm moves angularly around the hub and thereby moves the roller to follow the outer circumference at a fixed radial distance therefrom; a pair of shoe assemblies, each mountable between the bending assemblies, for engaging the pipe between the bending assemblies and securing the pipe as it is bent; and wherein a pipe is insertable between the roller flange and hub flange of both bending assemblies simultaneously, such that the pipe may be bent is a complex shape by operating both bending assemblies.
