Bending tool

Abstract

A bending tool for bending tubing, the bending tool includes first and second bend bodies that respectively include first and second arcuate channels. A central channel is cooperatively formed between the first and second bend bodies, and tubing partially disposed in the central channel may be bent around either of the first or second bend bodies to impart a desired bend. An attachment may be provided on the bending tool for releasably coupling the bending tool to another tool.

1 . A bending tool, comprising:
 a first bend body;   a second bend body adapted to couple to the first bend body in a fixed position relative to the first bend body, wherein the first and second bend bodies respectively include first and second arcuate channels; and   a central channel cooperatively formed between the first and second bend bodies and adapted to receive a tube, wherein the first and second arcuate channels extend from the central channel.   
     
     
         2 . The bending tool of  claim 1 , wherein at least one of the first and second bend bodies includes an attachment adapted to releasably couple to another tool. 
     
     
         3 . The bending tool of  claim 1 , wherein the first and second bend bodies are coupled to a base. 
     
     
         4 . The bending tool of  claim 1 , wherein the first and second arcuate channels each have a substantially semi-circular cross-section that is adapted to substantially match the outer cross section of a tube to be bent. 
     
     
         5 . The bending tool of  claim 1 , wherein the first and second arcuate channels each include an arcuate bottom surface and channel sides that extend from the arcuate bottom surface. 
     
     
         6 . The bending tool of  claim 1 , wherein the first and second bend bodies respectively include first and second straight channels, wherein the first and second straight channels respectively extend from the first and second arcuate channels. 
     
     
         7 . The bending tool of  claim 6 , wherein a first angle between the central channel and the first straight channel defines a first maximum bend angle, and a second angle between the central channel and the second straight channel defines a second maximum bend angle. 
     
     
         8 . The bending tool of  claim 7 , wherein the first maximum bend angle is about 180 degrees. 
     
     
         9 . The bending tool of  claim 2 , wherein the attachment is a blind bore. 
     
     
         10 . The bending tool of  claim 2 , wherein the attachment is an aperture. 
     
     
         11 . The bending tool of  claim 10 , wherein the aperture has a substantially square shape that is adapted to releasably couple to a lugged tool. 
     
     
         12 . A bending tool, comprising:
 a first bend body;   a second bend body coupled to the first bend body;   first and second arcuate channels respectively disposed on the first and second bend bodies;   a central channel respectively formed between the first and second bend bodies;   a base coupled to the first and second bend bodies; and   a handle coupled to the base.   
     
     
         13 . The bending tool of  claim 12 , further comprising third and fourth arcuate channels that extend from the central channel in a direction opposite of the first and second arcuate channels. 
     
     
         14 . The bending tool of  claim 13 , further comprising a first straight channel extending between the first and third arcuate channels, and a second straight channel extending between the second and fourth arcuate channels. 
     
     
         15 . A bending tool, comprising:
 a base;   a first bend body coupled to the base;   a second bend body coupled to the base;   a central channel cooperatively formed between the first and second bend bodies; and   first and second arcuate channels respectively disposed on the first and second bend bodies, wherein the first and second arcuate channels cooperatively form a circle with the central channel.   
     
     
         16 . The bending tool of  claim 15 , wherein the first and second bend bodies respectively include respective first and second chamfered portions disposed proximal to the central channel. 
     
     
         17 . The bending tool of  claim 15 , wherein at least one of the first and second bend bodies includes an attachment. 
     
     
         18 . The bending tool of  claim 17 , wherein the attachment is a square-shaped aperture that is adapted to releasably couple to a lugged tool. 
     
     
         19 . The bending tool of  claim 15 , wherein each of the first and second arcuate channels include an arcuate bottom surface and channel sides that extend from the arcuate bottom surface.
