PROBLEM TO BE SOLVED: To provide a bending tool capable of strongly and precisely bending a deep angle of not less than 90°without using an excessive mechanism such as a motor and a cylinder. SOLUTION: A cutting edge 5 is temporary sent to a position preventing jamming. Then, a cutting tool is descended. A tip end 65 of one low cutting tool is descended to a position at least lower than a top of the cutting edge 5, and the cutting edge 5 is retracted. The cutting edge 5 is retracted by the amount of finally sending. An end cutting device is composed of a miter cut unit of the cutting edge 5 provided at the side of the automatic bending machine, and a straight cut unit. COPYRIGHT: (C)2007,JPO&INPIT
