The invention discloses a wiring cutter head. The wiring cutter head comprises a cutter body, wherein a cutter point is arranged on one side of the cutter body; the lower part of the
cuter point is a cutter setting surface; the
vertical distance between the front side of the cutter setting surface and the point end of the cutter point is 0.1 mm; one end of the cutter setting surface is a
diagonal cutting surface inclined towards the direction of the cutter point. The invention further discloses a method for preparing a wire exposed type electric
smelting pipe fitting and the obtained electric
smelting pipe fitting; the method comprises turning and wiring steps. The thickness of the cutter setting surface is added, the
vertical distance between the front side of the cutter setting surface and the cutter point of the cutter head is shortened, the
copper wire arrangement depth is shortened, the
diagonal cutting surface is arranged on the cutter setting surface, and one side
flange is compressed but another side
flange is not pressed when the cutter setting surface is used for
grinding a
copper wire, so that the firmness of the
copper wire is guaranteed, a part of the
copper wire is exposed outside the inner surface of a plastic
pipe fitting and is in good contact with the
pipe fitting, the process is realized through the cooperation with a corresponding technology, and the obtained wire exposed type electric
smelting pipe fitting is reasonable in
copper wire arrangement, firm in the
copper wire and small in ellipticity.
