摘要：A manually operable tube flaring tool for providing a partial flare in the end ofa deformable tube. The tool includes a flaring head defining an annular flaring surfaceand a cylindrical pilot portion projecting axially from the flaring surface to be received inthe tube end for guiding the flaring surface axially against the distal end of the tubeduring the flaring operation. The tool further includes a support for fixedly positioningthe tube end coaxially adjacent the flaring surface of the flaring head. The supportdefines an improved recess configuration providing a controlled buckling of the tube endby the forceful engagement therewith of the flaring surface wherein the buckled tubeend defines preselected frustoconical inner and outer portions. The support may furtherdefine a conventional single flare recess opposite the partial flare recess whereby thetube may be used selectively to provide either of the partial or single flare flaringoperations. The tube clamp may be defined by one leg of the U-shaped body and acooperating clamp block movably carried by the body and adjustably positioned by athreaded member threaded through the other leg of the body.
