Leakage-proof structure for blanking of punching machine

The utility model discloses a material leakage prevention structure for blanking of a punching machine, which belongs to the field of material leakage prevention of blanking of punching machines and comprises a mounting frame, a collecting tank, a mounting box, a discharge pipe, a sliding cambered surface, a baffle, a rotating plate, an upper magnet and a lower magnet. The installation box on the installation frame is connected to the discharging pipe, when the discharging pipe discharges materials outwards, the materials are discharged outwards, firstly, the baffle is impacted to preliminarily consume energy of the materials, and then the materials with low speed slide downwards along the sliding arc face and are attached to the sliding arc face under the action of the lower magnet at the lower portion of the sliding arc face. The discharge is slowed down under the friction force; and the high-speed material impacts the rotating plate after being cast rightwards, is adsorbed to the rotating plate under the a
