用转模拉丝时,一方面钢丝穿过拉丝模孔作直线运动,同时拉丝模还围繞钢丝作圆周运动,以达到减小钢丝直径的目的。 (一) 转模结构: 我们试验研究和试生产所采用的转模拉丝方法,对拉丝机主体都未作更改,只是把原来的固定模座换成转模即 Wire drawing with the transfer mode, on the one hand the wire through the drawing die hole for linear motion, while the drawing die also made circular motion around the wire, in order to achieve the purpose of reducing the wire diameter. (A) transfer mold structure: Our pilot study and trial production of the transfer mode drawing method, the main body of the drawing machine have not been changed, but the original mold base into a transfer mold that is
