The invention relates to a hooked cutting device which comprises an upper die plate, a lower die plate, a first beating block located on the upper die plate, a lower die block located on the lower die plate, a lower die insert on the lower die block, a cutter and a product holding table for holding a product. A cutter fixing seat is vertically inserted in the lower die block. A spring is butted between the bottom of the cutter fixing seat and the lower die plate, so that the cutter fixing seat can move up and down relative to the lower die block. The upper part of the cutter fixing seat is fixedly provided with the cutter after penetrating through the lower die insert, the section of the cutter is hooked, and the cutting edge of the cutter right faces the product obliquely downward. The product holding table is arranged adjacent to the lower die insert. The first beating block on the upper die plate is correspondingly arranged on one side of the product holding table relative to the cutter, and can cooperate with the product holding table to drive the product holding table to move toward the cutter side. Die cutting with small allowance can be realized through the lateral movementof the product and the vertical movement of the hooked cutter. Moreover, the hooked cutting device has accurate positioning and high processing accuracy.
