对于很多冲模来说,冲裁凸模工作时的稳定性对其使用寿命影响很大。凸模的稳定性是指凸模冲裁板料时,保持正常冲裁间隙的能力。如果不能满足一定的稳定性条件,则凸模的弯曲变形和工作(刃口)端的偏移就会使正常冲裁间隙发生过大的变化,刃口局部负荷激增,产生严重磨损或崩刃,细长凸模甚至发生折断。为了保证冲模的正常工 For many punches, the stability of punching punch working hours have a significant impact on their service life. The stability of the punch refers to punch punch plate, the ability to maintain normal blanking gap. If you can not meet certain stability conditions, the bending deformation of the punch and work (edge) end of the offset will make the normal blanking gap too much change, the local surge in the blade edge, resulting in serious wear or chipping, Slender punch even broken. In order to ensure the normal die work
