pulling force

In order to obtain the stress distributing rules of the forming process of short plug drawing tube and the differences of drawing force,pulling force and dimension precision under different dies,FE method was used and FE model of the plug drawing tube under different dies was built.

为了获得不同的模具下短芯棒拔管成型过程中的应力分布规律以及不同模具对短芯棒拔管拔制力、芯棒后拉力和尺寸精度的影响规律,利用有限元的方法,建立了不同模具下短芯棒拔管成型的有限元模型。

This paper compares the corrosion behaviors and microstructures of the galvanizing first and drawing afterwards and those of the drawing first and galvanizing afterwards hotdip zinc coating of the steel wire by sea water simulated test and SEM and EDS.

采用海水模拟试验比较了先镀后拉和先拉后镀热镀锌钢丝的耐蚀性,利用扫描电镜和能谱仪对镀层微观组织和成分进行分析,结果表明,先镀后拉钢丝镀层由表及里是三层组织,既致密的η相、ζ相和δ1相,先拉后镀钢丝镀层也由η相、ζ相和δ1相组成,但ζ相呈分散状。

The process of drawing after medium galvanizing by dipping is a drawing method adding bright steel wire drawing between heat treatment and galvanizing by dipping.

中镀后拉工艺是在先镀后拉工艺的热处理和热镀锌之间插入光面钢丝拉拔。
