High-strength and high-toughness special-shaped armor forming die and process

The invention provides a high-strength and high-toughness special-shaped armor forming die and process, and belongs to the technical field of machining, the high-strength and high-toughness special-shaped armor forming die comprises a cone-like reaming head and a square extrusion die, and the cone-like reaming head comprises a front end core rod, a middle conical grinding head and a tail fixing clamping groove. A high-strength and high-toughness special-shaped armor forming process comprises the following steps that an N50 primary pipe blank is manufactured; heating the N50 primary tube blank to 1150-1200 DEG C by using a heating furnace; n50, broaching the primary pipe blank; an extruding machine is used for extrusion forming along the square extrusion die, and an N50 tertiary pipe blank is manufactured; n50 third-level pipe blank acid pickling is carried out; the N50 tertiary pipe blank is subjected to drawing forming, and an armor prototype is obtained; and the armor prototype is annealed to relieve stress
