Abstract
Tube bending apparatus comprising a lower support carrying a mandrel having a bending groove providing a bend axis, and an upper support mounted on the lower support for rotation about the bend axis and carrying a forming member for urging a tube between the mandrel and forming member into the bending groove on rotation of the upper support relative to the lower support. The upper support is adapted to be rotated relative to the lower support through a drive shaft arrangement extending downwardly from the lower support and coupled with a drive unit having an output coupling coaxial with the drive shaft and transverse to the axis of the drive motor of the drive unit. A stand supports the bending apparatus and drive unit relative to an underlying support surface during operation of the bending apparatus. The lower support is provided with angularly spaced apart abutment surfaces corresponding to different bend angles for a tube to be bent, and the upper support member is provided with a stop member which is selectively adjustable to engage any one of the abutment surfaces to provide the corresponding bend angle as well as a selectable degree of overbend of the tube relative to the bend angle.
