Abstract: Disclosed is an apparatus for defining a bending or welding groove in a cutting blade. A pair of fixed blocks are fixed to a base of a cutting blade forming apparatus. A slider is slidably coupled to each fixed block, and a bit support block is slidably coupled to the slider. The slider and the bit support block are respectively operated by first and second operating mechanisms. First through fourth guide parts are formed on the fixed block, slider and bit support block, to constitute dovetail joints. The first guide parts of the fixed blocks and second guide parts of sliders are formed to have a slope, such that, as the sliders are lowered, they are horizontally moved toward each other. A lower portion of a broaching bit is formed as a supporting surface, and at least one broaching edge portion is formed above the supporting surface portion.
