Metal bending device

Abstract

A metal stock bending device comprises a main body arranged to be secured to a suitable support structure and a handle assembly mounted to the main body on a shaft having a substantially vertical axis arranged such that the handle rotates on the shaft about the axis. The body is arranged to support an interchangeable die on the shaft. The handle is arranged to support an interchangeable shaper die having an axis parallel to the shaft axis positioned on the handle such that the shaper die is arranged to follow a path of a circle about the shaft axis. A block assembly arranged to support a metal stock to the die. Movement of the shaper die about the die on the shaft engages the metal stock supported by the block assembly such that the rotation of the handle forces the stock to take the shape of the die.

1 . A metal stock bending device comprises: 
 a main body arranged to be secured to a suitable support structure;    a handle assembly mounted to the main body on a shaft having an axis arranged such that the handle rotates on the shaft about the axis;    an interchangeable die on the shaft;    an interchangeable shaper die on the handle having an axis parallel to the shaft axis positioned on the handle such that the shaper die is arranged to follow a path of a circle about the shaft axis;    and, a block assembly arranged to support a metal stock to the die;    wherein movement of the shaper die about the die on the shaft engages the metal stock supported by the block assembly;    wherein rotation of the handle forces the stock to take the shape of the die.    
     
     
         2 . The device according to  claim 1  wherein the main body is arranged to receive a depth control mechanism for regulating the length at which the metal stock is shaped.  
     
     
         3 . The device according to  claim 1  wherein the die has a circular diameter.  
     
     
         4 . The device according to  claim 3  wherein the die has a radial groove.  
     
     
         5 . The device according to  claim 1  wherein the die has an edge for angular bends.  
     
     
         6 . The device according to  claim 1  wherein the block assembly has a threaded shaft wherein a block is coupled to an end adjacent the die.  
     
     
         7 . The device according to  claim 6  wherein the threaded shaft is arranged to be rotated through a portion of the main body such that the block engages the metal stock at the die.  
     
     
         8 . The device according to  claim 6  wherein the block has an opposing face relative to the threaded shaft which corresponds with the type of metal stock.  
     
     
         9 . The device according to  claim 8  wherein the face is flat.  
     
     
         10 . The device according to  claim 8  wherein the face has a groove parallel to the positioned metal stock.
