TUBE BENDER

摘要

A tube bender for bending tubes of different diameters selectively and one at a time is disclosed. The bender has a pair of pivotally connected handles respectively connected to a form wheel and a form shoe. The wheel has a plurality of tube engagement grooves, the grooves each being generally arcuate in cross section in both axial and orthogonal planes of coss section. The shoe includes a plurality of grooves of arcuate cross section in an axial plane. Each of the shoe grooves is complemental with a different and associated one of the wheel grooves. A tube holder is adjustably positioned in fixed relationship with the wheel when a tubular work piece is engaging one of the grooves in a bending operation. The radii of each of the arcuate wheel groove cross sections is different than the radii of each other corresponding wheel groove cross sections in both the axial and the orthogonal planes.
