Integral forming die and integral forming method for circumferential wave-shaped part

The invention discloses an integral forming die and an integral forming method for a circumferential wave-shaped part. The integral forming die comprises a base assembly, a positioning ring fixed to the base assembly, an inner shape assembly in sliding connection with the base assembly in the radial direction, an outer shape assembly in sliding connection with the positioning ring in the radial direction, an upper die assembly installed on a machine tool and a punch assembly installed on the upper die assembly, wherein the positioning ring is adhered with the outer mold surface of a cylindrical section; the upper die assembly and the punch assembly are synchronously pressed downwards, so that the inner shape assembly moves outwards in the radial direction under the extrusion action of the punch assembly and extrudes the inner shape of the cylindrical section and the inner shape of the wave-shaped section, and the outer shape assembly moves inwards in the radial direction under the extrusion action of the uppe
