ABSTRACT:
Tube flaring apparatus for forming a radially outwardly extending flange at one end of a hollow malleable cylindrical conduit including a rotating spindle journaled on a stationary housing and mounting a chuck at one end thereof. The chuck cantileverly supports an axially extending conduit to be flared. A flaring tool is mounted for movement between an axially outer radially inner position removed from the conduit and an axially inner, radially outer position bearing against the inner surface of the outer end of the conduit to radially and axially displace the end to form a flange. The flaring tool is coupled to a piston rod axially driven by a fluid operated cylinder which is mounted in fixed relation relative to the chuck at the axially opposite end of the rotating spindle.
