A method for preparing exposed wire type electric fusion pipe fittings and the obtained exposed wire type electric fusion pipe fittings

Abstract

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.

Description

technical field [0001] The invention relates to a wiring cutter head, a method of using the wiring cutter head to prepare exposed-wire type electric fusion pipe fittings and the obtained exposed-wire type electric fusion pipe fittings. Background technique [0002] The wiring cutter head used by the non-exposed electric fusion pipe fittings is the original factory wiring cutter head equipped with the wiring machine. The wiring cutter head is as follows: figure 1 , 2 , 3 shows: the horizontal distance d between the tool point 12 and the tool setting surface 13 is 1.5mm, the distance is long, resulting in a deep wiring depth of the tool head, and the effect of exposed lines cannot be achieved. Whether it is adjusting the program or adjusting the tool setting point, It is impossible to produce exposed wire electrofusion pipe fittings. The only way to produce exposed wire electrofused pipe fittings is to finish the last process and increase the cutting depth to make it reach th...
