Assembly and setup of main dies • Compressive Stress 压应力
4. COK Speed
剪刀速度
5. Lubricants
润滑
6. Types of COK
剪刀类型
•Harder materials need bigger clearance, more tool relief & higher speed 当剪切较硬的线材时, 需要更多的间隙, 表面退让(退剪槽)和更快的速度. •Too loose the COD / COK diameters will bend the blank and cause taper ends 剪刀/ 剪体的内孔直径太大时, 会造成线材弯曲, 线材末端缩小. •Shearing without lubricants causes short tool life 无润滑剪切会缩短模具寿命.
