when the blanking device works, firstly, materials are manually put into the blanking limiting hole 220, then the blanking feeding plate 22 moves rightwards, meanwhile, the middle driving plate 24 synchronously moves leftwards, until the blanking limiting hole 220, the blanking forming hole 101 and the central driving limiting hole 240 are positioned on the same vertical line, at the moment, the blanking upper die 30 descends to perform blanking, thus, the blanked materials fall into the central driving limiting hole 240, then the blanking feeding plate 22 moves leftwards, meanwhile, the middle driving plate 24 synchronously moves rightwards until the initial state is returned, at the moment, the central driving limiting hole 240, the punching avoiding hole 106 and the punching forming hole 250 are positioned on the same vertical line, then the punching upper die 40 descends to perform punching, then the discharging guide plate 28 moves leftwards, meanwhile, the punching lower die 25 synchronously moves rightwards, when the discharging guide plate 28 is positioned at the leftmost end, the punching lower die 25 is positioned at the rightmost end, the central drive limiting aperture 240 is completely exposed directly above the discharge guide 28 so that the material falls onto the discharge guide 28 and slides along the discharge guide 28.
