;Lesson 2 Machine set-up procedure;Step 1 第一步;Step 1 第一步;一般地线径小于 模具孔径 0.02-0.04 Normally wire diameter is smaller 0.02-0.04 than tooling hole size;Step 2 第二步;调整剪刀孔对齐顶料针 剪刀移动到最顶端，顶料针基本处于剪刀孔的中心且要露出剪刀外面 一点(图1)，否则短料时，料头会留在刀孔内导致剪刀和顶料针损 坏(图2)，但也不可太长,顶料针的弧面会撞到剪刀的背面(图3)。 COK pusher PIN alignment Let COK move to the up end,the PIN is basically in the center of COK hole and ought to be out of the front surface of COK a little(picture1),otherwise when wire feeding is problem, the shorter pieces of cut off will be stay in the COK hole so that COK and PIN are damaged(picture2),but the part out of COK also can’t be too long,the arc surface of PIN would beat the back Surface of COK(picture3).;Step 3 第三步;注意事项 Note;2. 一冲接料的调整 For 1st punch taking cut-off adjustment;3.调整顶料针送料的速度太慢，一冲接不住料； 太快， 下料会膨胀，严重时会粘在一冲内造成顶料针和剪刀损坏。 Adjusting transfer speed of kick out PIN too slow,1st punch can’t take in cut-off,too fast,cut-off would expand,seriously it will result in kick out PIN and COK damaged due to cut-off sticking in the hole of 1st punch. ;注意事项 1.主模针一定要露出主模面,大概 2mm, 2.当击打机构移动到最前端时, 击打机构和击打针之间一定要有间隙,否则主模针大头部容易被敲断; 但间隙也不可太大,螺丝会退不出主模来.如图:nm. Notice 1.MDP must be out of the surface of MD around 2mm, 2there must be a little gap between kick out mechanism and strike out pin when kick out mechanism moves to the most front end,otherwise the bigger part of MDP will be broken easily;but too big gap will result that the screws can’t be kicked out from main die.;Step 5 第五步;2.安装二冲及应注意的事项 Set 2nd punch and things should note ;3.根据图纸的要求完成螺丝的调整 Finishing the adjustment of screw basing the drawing spec.;如何辨别螺丝头的方向? How to determine the direction of screw head?;5.调整螺丝从主模退出 Adjusting screw to be kicked out from main die;Step 6 第六步;2.进料系统并调整 Checking feed system if proper and adjusting;压紧机构 Mechanism For compacting;慢 Slow; 3.观察螺丝的稳定性并调整 如果螺丝头或二冲穴中心不稳，首先检查机器的间隙或是否有螺丝松动并调整， 其次检查一冲口径是否太大或太小并修理。 如果螺丝长短不一，检查主模孔的光洁度并抛光。 3.
