Patent ID: 7426846

Claim:
An automatic bending machine for automatically bending a strip blade material, and intermittently feeding a strip blade material through a nozzle until the strip blade material is jutted out from a nozzle gate at an end of the nozzle, to cause a bending tool to be turned in one of a clockwise direction or a counterclockwise direction, to strike the strip blade material for bending the same, the automatic bending machine comprising: a CW-direction bending tool and a CCW-direction bending tool, each being provided with a bending tool support extending at right angles thereto and having a concentric hole at a top and at a bottom of each of the CW-direction bending tool and the CCW-direction bending tool, respectively, the CW-direction bending tool and the CCW-direction bending tool being superposed one upon the other, a nozzle column or a reinforcing rod provided on a top of the nozzle, and penetrating through the concentric hole, at the top of each of the CW-direction bending tool and the CCW-direction bending tool; and a lower belt wheel having a protrusion provided on a top thereof, the lower belt wheel capable of being turned under a control of a computer, the lower belt wheel being in contact with the bending tool support of each of the CW-direction bending tool and the CCW-direction bending tool.
