Abstract

The utility model discloses a scrap jumping preventing mechanism with airflow holes of a high-speed stamping die. The scrap jumping preventing mechanism with the airflow holes of the high-speed stamping die comprises a female die and blanking knife edges arranged on the female die, wherein the airflow holes are further formed in the female die, and the airflow holes are communicated with the blanking knife edges. Due to the facts that the airflow holes are further formed in the female die, and the airflow holes are communicated with the blanking knife edges, scraps are squeezed into the blanking knife edges in the process of stamping of materials; meanwhile, air flows into the blanking knife edges through the airflow holes, the scraps are timely discharged to the bottoms of the blanking knife edges through airflow, the airflow generates downward resistance in the blanking knife edges, and resistance to upward pull of the scraps is improved so that the scraps cannot jump back to the surface of the female die. The improved scrap jumping preventing mechanism with the airflow holes of the high-speed stamping die can completely solve the problem that the scraps jump out, the phenomenon that scraps jump is avoided, jump preventing resistance to the scraps and production efficiency of finished products are improved, and the defective rate and production cost are reduced.
