(2) pickling and cold-drawn: the hydrochloric acid solution immersion 10-15min by wire rod concentration being 10-12%, clean water is clean, carries out cold-drawn after oven dry;
(3) shaping: a material loading place title of the wire rod after cold-drawn being connected on cold headers, the hexagonal blank of required size can be got according to the mould in cold headers;
(4) tapping: shaping hex nut blank is poured in the funnel on tooth machining unit and carry out tapping;
(5) heat treatment: the hex nut blank after tapping is placed in stove keeps 120-150min under 320-340 DEG C of condition, then be warming up to 600-640 DEG C, keeps 60-90min, oil cooling is to 320-340 DEG C, insulation 60-90min, air cooling, to normal temperature, can obtain hex nut.
The processing technology of described a kind of hex nut, the hex nut blank obtained after tapping is heat-treated after grinding again.
The processing technology of described a kind of hex nut, described Ginding process is magnetic grinding.
According to the hex nut that the processing technology of described a kind of hex nut obtains.
Beneficial effect of the present invention is as follows:
Machining process of the present invention is simple, and the hex nut qualification rate obtained is high, by pickling, eliminates the oxide-film of wire surface, adds the greasy property of wire rod, decrease scratch, improve the hardness of hex nut after shaping again by heat treatment.
