摘　　要：为解决特细金属丝整经过程中易断丝,张力控制难度大等问题,介绍特细金属丝整经难点,对比矩形筒子架和V型筒子架的优缺点,设计V型对称错位结构筒子架;阐明单丝张力控制的意义,并从单丝张力控制方法及闭环控制等方面进行分析,设计一种重锤摩擦盘式单丝张力控制机构,并对无单丝张力控制、重锤张力杆式调节和重锤摩擦盘式调节三种控制方式进行对比试验。指出:V型对称错位结构筒子架,能有效减小金属丝在筒子架上的摩擦力及金属丝交叉问题;重锤摩擦盘式控制方式较无单丝张力控制和重锤张力杆式,达到稳态的时间快,单丝张力稳定性好,可将单丝张力误差控制为±3cN,适用于直径为0.012mm^0.050mm的金属丝整经。To solve the problems with super fine wire breakage and difficulty in tension control in the process of warping, introduction is made to the warping bottleneck, comparison is done to the rectangular creel and V-type creel on their advantages and disadvantages, and a symmetric V-type dislocation structured creel is introduced. Significance is highlighted on monofilament tension control.A hammer disc friction monofilament tension control mechanism is introduced from the aspects of wire tension control and closed loop control.The three control modes were compared including free filament tension control, tension rod weight regulation and weight ad- justing friction disc.It is pointed out that the creel of the V-type symmetric dislocation struc- ture can effectively reduce friction of the metal wire on the cylinder frame and wire lapping~ weight adjusting friction disc can access to steady state in short time as compared with the oth- er two structures and gain good stability of monofilament tension, consequenly making the tension control error within ±3 cN,applicable to wire warping of diameter between 0.012 mm-0.050 mm.
