| 摘 要： | 通过药芯焊丝拉拔应力分析，建立了冷轧钢带法制造药芯焊丝的拉拔力计算模型，分析了影响拉拔力的因素。影响药芯焊丝拉拔的因素很多，其中钢带的力学性质、焊丝的变形程度、拉丝模的内孔尺寸、拉拔速度、摩擦与润滑条件对拉拔应力影响较大。在低速拉拔时，拉拔应力随拉拔速度的增加而增大。中速拉拔时，拉拔应力随拉拔速度的增大而下降。继续增大拉拔速度，拉拔应力变化不大。

| Abstract: | By analyzing the drawing stress of flux-cored wire(FCW),a new model for the calculation of the drawing force for FCW was formed.The factors that influence drawing force were also discussed.Mechanical properties of the steel strip,deformation of flux-cored wire,the hole size of dies,drawing speed,friction and lubrication conditions had obvious effects on the drawing stress.The drawing stress increased with the speed rise at low speed.At moderate speed the drawing stress decreased.The drawing stress did not change when the speed increase further. |
