Cutting die for outer edge of non-standard part

The invention relates to a cutting die for an outer edge of a non-standard part. The cutting die comprises a layered cutting die; the layered cutting die consists of a plurality of shaping blades; a cutting cavity is formed in each shaping blade; the cutting cavity of each shaping blade has cutting output, and also comprises a pressure device; pressure is applied to a workpiece by the pressure devices to push the workpiece to move in the layered cutting die. According to the cutting die for the outer edge of the non-standard part, disclosed by the invention, progressive cutting is performed on the outer edge of the workpiece through the multiple layers of shaping blades in the layered cutting die to machine the workpiece into a special-shaped non-standard part; the cutting die disclosed by the invention is simple and easy to operate; on the premise that volume production of the special-shaped non-standard part is realized, the special-shaped non-standard part is enabled to reach precision, surface roughness a
