ABSTRACT:
A tube bending apparatus is provided for placing a plurality of bends in an elongated tube. The apparatus includes a position sensor for sensing at least one location on the tube for assessing the accuracy of the bends placed therein. The apparatus further includes a programmable bender having a bend die and a clamp die for securely engaging the tube and bending the tube through a selected degree of curvature. A collet assembly is operative to axially and rotationally position the tube for each sequential bend. A pressure die boost and a collet assembly are provided for exerting axial pressure on the tube to urge the tube into the bend. The amount of axial force is programmed and selectively controllable in response to sensed operating conditions. A lubricated mandrel is programmably operative to be placed inside the tube. The movement of the mandrel is programmable and the flow of lubrication therethrough is both programmable and condition responsive.
