Fast change fold-a-way cross bow swing arm multiple die tubing bender

Abstract

A tubing bender device includes a frame, handle, ratchet mechanism, slide rod and a frame notch. The tubing bender may be easily disassembled and assembled into a forward or reverse configuration through the use of connectors, two brackets and a bending mandrel. Reversibility is also provided by a cross bow bar support releasably secured to either the slide rod or to a bracket. The cross bow bar support may also be inverted to position die heads in either an upward or downward direction. Repositionable die heads may also be rotated relative to the support into an operative configuration when bending smaller diameter tubing. The repositionable die heads are rotated relative to the support into a non-operative configuration when bending larger diameter tubing.

         27 . The tubing bender device of  claim 26 , wherein movement of the handle with respect to the frame advances the ratcheting mechanism that moves the slide rod. 
     
     
         28 . The tubing bender device of  claim 21 , wherein the plurality of die heads have a degree of revolution relative to the cross bow bar support. 
     
     
         29 . The tubing bender device of  claim 21 , further comprising a plurality of repositionable die heads having a degree of rotation relative to the cross bow bar support. 
     
     
         30 . The tubing bender device of  claim 29 , wherein the plurality of die heads are located on a bottom side of the cross bow bar support and the plurality of repositionable die heads are located on a top side of the cross bow bar support. 
     
     
         31 . The tubing bender device of  claim 29 , wherein the plurality of repositionable die heads are rotatable about an axis. 
     
     
         32 . The tubing bender device of  claim 31 , wherein the plurality of repositionable die heads, when in a non-operative position, are located in a different plane than a plane established by the bending mandrel and plurality of die heads. 
     
     
         33 . The tubing bender device of  claim 21 , wherein the plurality of die heads share a mid plane with the bending mandrel. 
     
     
         34 . The tubing bender device of  claim 21 , wherein the tubing bender device has a first bending configuration for bending a pipe in a first bending direction and a second bending configuration for bending the pipe in a second bending direction opposite the first bending direction. 
     
     
         35 . The tubing bender device of  claim 34 , wherein the plurality of die heads extend upwardly from the cross bow bar support in the first bending configuration. 
     
     
         36 . The tubing bender device of claim of  claim 34 , wherein the plurality of die heads extend downwardly from the cross bow bar support in the second bending configuration. 
     
     
         37 . The tubing bender device of  claim 34 , wherein the mechanism comprises a mechanism selected from the group consisting of: a ratcheting mechanism and a motorized mechanism. 
     
     
         38 . The tubing bender device of  claim 21 , wherein the cross bow bar support is located perpendicularly with respect to the frame.
