针织毛衫CAD中缩针工艺制定

Needle retracting technology setting of knitted sweater CAD

文章在对针织毛衫CAD中缩针的设定方法、应用方式研究及工艺分析的基础上指出缩针设定在工艺单中以中留针数的方式显示,及固定夹边留针数和固定中间留针数2种缩针方式中间隔针数、中留针数和夹边留针数的计算方法。缩针用于组织变化时,针对不同组织、机号、针床对位方式有3种缩针位置,缩针有固定间隔缩针、平均缩针和缩工字褶等工艺方式,最大移床针距与缩针针数相关,缩针针数较大时要分批缩针;罗纹组织缩针时要进行缩坑处理,说明了缩褶效果的影响因素和应用。

This paper introduces the setting,application mode and process analysis of needle retracting.It points out needle retracting set shows its process way with the number of center needles in the process sheet and proposes calculation method of retracting interval needles number and center needles number for two processing way of fixed side and fixed center.It illustrates three kinds of needle retracting position for organization change according to the different organization,machine gauge,needle alignment mode.It points out fixed interval retracting,average retracting and fold retracing process as well as the relationship between retracting needle number and maximum bed moving distance.When the retracting needle number is large,it needs several batches of retracting operation.The rib construction usually retracts two needles a time.It also proposes influence factors and application of retraction effect.
