为了适应冲裁件的更换并提高其生产效率,实现冲模的通用可调化就显得十分迫切了。 一、参数L、t及τ的处理 要实现一组零件的冲裁,首要的条件是有一个足够的冲裁力P,且成组后的冲裁件所需的冲裁力 In order to meet the replacement of blanking parts and improve their production efficiency, to achieve universal adjustable die becomes very urgent. First, the parameters L, t and τ processing To achieve a group of parts blanking, the first condition is to have a sufficient blanking force P, and blanking force required after the blanking group
