1、Simple Mistakes Costly Errors in Dies,Mike Augustyn July. 23rd, 2008,模具中的一些简单错误， 发生后却需大力才能解决,Die Maintenance 模具整备 Setup Setup Material 材料 Pilots and Inserts 定位针和下刀 Shims 垫片 Tooling 备件 Strippers 盖板 Screws 螺钉 Detectors 探测仪 Lubrication 润滑 Dos and Donts 可做和不可做,Overview,Die Maintenance模具整备,Check for Brok
2、en or Worn on Tooling检察备件上是否有损坏或破损 Replace Worn Screws 更换破损螺丝 Check Last Progression for Any Tool Marks 检查最后一条样带看是否有压伤 Grease the Die 给模具上润滑油 Double Check for Loose Screws 再次检查是否有松动了的螺丝 Remove all Springs From Die and Close by hand on bench to ensure Die Closes Properly 从模具里面去掉所有弹簧，并在模具工作台上闭合模具以确保模具
3、正确闭合 Sharpen Tools Everytime die is on bench For C/O or die preparation. 模具每次在工作台上准备换型号或模具整备时，研磨备件。,SETUP,Improper Feed Table Height 送料台高度不正确 Improper Feed Setting 布距设置不正确 Improper Pilot Release Pilot释放角不正确 Too Long Mounting Screws 安装螺钉太长 Check for Burrs on Die Shoes 检查下模上是否有毛刺 Check for Burrs on Ad
4、aptor Plates & Bolster Plates 检查适配板和垫板上是否有毛刺,Material材料,Look for Dents or Damage on Material 观察材料上是否有凹痕或损坏 Look and Feel for Burrs on Material 观察并触感材料上是否有毛刺 Look for Plating Build-up 观察材料上是否有电镀堆积物 Check for Too Wide Material 检查材料是否太宽 Stock the Die with Bow-up 向上弯曲穿料,Pilots and Inserts,Check for Bent
5、 or Broken Pilots 检查定位针是否有弯曲或破损 Check Pilots Inserts after Jam to Ensure Insert is not Slugged Up 卡料后检查定位下刀，确保下刀下没有碎片,Shims垫片,Always Use a Common Shim 始终使用普通垫片 Never Shim the Tooling from Side to Side不要在备件的边上垫垫片 If you Shim Tooling Front to Back, be sure you do NOT have Tooling interference如果在备件的前面或
