The invention relates to the technical field of machining equipment, and discloses a convex hull pneumatic device based on an automobile aluminum plate blanking die, the convex hull pneumatic device comprises a die body, an air tank and an air cylinder, the air tank is fixed on the side wall of an upper die of the die body, the air cylinder is embedded in a pressing surface of the upper die, the air tank is used for supplying air to the air cylinder, and an impact pin is slidably mounted in the upper die; the sliding direction of the impact pin is perpendicular to the pressing face of the upper die, a groove corresponding to the impact pin in position is formed in the pressing face of the lower die, and the air cylinder is used for driving the impact pin. The blanking die has the beneficial effects that when the blanking die is used for blanking, the convex hulls are machined at the allowance positions of blanks through striking of the impact pins, the convex hulls abut against the plane of an aluminum plate
