In the thesis, the cutting of the head of the 1.5 swing scissors is researched, and makes some improvments of partial strcture.First, the thesis has discussed the position of the rolling mill of sharp steel in the national economy, and makes the general instruction for 300/500 unit plane arrangement. Next, introducing the structural characteristic of the swing cutting and the method and content of the research .According to exising equipment condition, analysing the exist problem in equipment production, the strcture of the major parts are reasonable to choosed. Then,according to the primitive parameter of the unit, I primarily choose the capacity of the main motor, and make the heat examination and overload examination, choose if satisfying the requirement, otherwise choose again until the examination is satisfyed. I make the strength examination for major element. As to gears, I make the strength calulation; as to crank, I caculated the curving stress and the crooked synthesis stress, examinationing the dangerous cross section, as well as the improment of the damages of the slide and the method of lubrication. Finally I caculated the economy appraisal and the reliablity of swing scissors.Through the work of this thesis, 1.5 swing scissors should certain raise in service life and product quality theoretically, but need the unceasing improvement in practice.Key-word: scissors, swing, main drive
