Modular punching-leveling integrated die for ring-shaped flaky powder metallurgy product

The invention discloses a mold for modular stamping and integration of annular flake powder metallurgy products. It includes an upper mold and a lower mold, the upper mold includes a base, the lower end of the base is fixed with a connecting column, the lower end of the connecting column is fixed with a punching head, and four mounting brackets are uniformly arranged around the base, Two pairs of mounting frames are formed opposite to each other, and a telescopic cylinder is respectively installed at the lower end of each mounting frame. The cylinder body of the telescopic cylinder is connected to the corresponding mounting frame through an elastic connection structure, so that the telescopic cylinder can move up and down. The piston of the telescopic cylinder A leveling head with a semi-circular cross-section is installed on the rod; a distance is left between the upper end surface of the leveling head and the lower end surface of the mounting frame; The blanking hole is located below the positioning hole and communicates with the positioning hole. The diameter of the positioning hole is equal to the outer diameter of the leveling head and the outer diameter of the workpiece. The diameter of the blanking hole is equal to that of the punching head. diameter of.
