Pass to count to Wisterch parameter , and the steel wire is different from the molding tool get in touch with the length, and settle the path the research taking the length work the stabber angle to get under differently pull to stir the term, mold core adoption of best severally why size, combine the best work stabber of research the Cape, and settle the path to take the length nextly steel wire is in the molding tool of have fever to measure, air inside dispel-heat calories, winding dispel-heat on the coil-canister , and its molding tool dispel-heat calories of, and cause the steel wire the temperature difference pass in and outing the molding tool to influence steel wire machine function, under the experiment inside pull to stir the term according to the same race different work stabber Cape half of adoption the Cape(7 degree,10 degree,12 degrees, the best mold Cape, experience mold Cape) settle the path to take the length(2-3 mm,3-4 mm,4-5 mms, theories length, experience length) to proceed to experiment, and get the conclusion, work stabber the Cape then is more big the steel wire get in touch with the length with

通过对Wisterch参数，钢丝与模具接触长度、定径带长度、工作锥角度的研究得到了在不同拉拨条件下模芯采用的最佳几何尺寸，并研究最佳工作锥角、定径带长度下钢丝在模具中的发热量、空气中散热量、卷筒上的散热量及其模具散热量的不同，导致钢丝进出模具的温度差别对钢丝机械性能的影响，在实验中根据同种拉拨条件下采用不同工作锥角半角、定径带长度进行试验，得出结论，工作锥角越大则钢丝与模具接触长度越短，钢丝变形越剧烈，在模具中发热量就越高，导致钢丝出模温度高，使钢丝强度、硬度升高，弯曲、扭转次数降低，并且降低模具使用寿命。在其它条件相同的情况下，定径带越长则钢丝与定径带简壁磨擦增大，使钢丝发热量加大，从而使钢丝强度、硬度略升高，弯曲扭转次数略降低但定径带的增大减小了钢丝变形产生的弹性后效使钢丝出模直径比较稳定。
