Abstract
PURPOSE: A simply, lightweight pipe bender excellent in the working efficiency of the bending work, obtained by interposing an expanding-and-constricting device for giving the turning forces in mutually opposite directions to two rotary working blocks which are connected with the common pivot so as to be mutually freely rotatable, between these two rotary working blocks.
CONSTITUTION: The operator turns the lever 17 so as to turn the screw rod 16 in one direction; hereby, the rotary working block 1 is turned to the direction A and the rotary working block 2 is turned in the direction B, in which both of rotary working blocks 1, 2 turn around the pivot 4. The mements in the directions A and B taking the bending die 11 as the fulcrum are applied to the pipe P which is thereby bent into the condition shown by the double-dotted chain lines. When the bending angle of the pipe P becomes the desired value, the turning action for the lever 17 is stopped, and the pins 14, 15 are pulled away, the side bending dies 12, 13 are detached, and the bending work for the pipe P is finished. This pipe bender, because of its simple construction and easy operation, can be used in common for the internal bending work and the external bending work; and besides, one operator alone can set the pipe in the bender and perform the bending work.
