The utility model discloses an electric explosion valve cutting piece. The electric explosion valve cutting piece comprises a first connecting piece, a shell welding piece, a second connecting piece and a cutting piece; the four parts are integrally formed sequentially to form a hollow blind cavity structure; the blind cavity structure comprises three parts, namely a conical surface cavity corresponding to the first connecting piece, a cylindrical surface transition section corresponding to the welding piece and the second connecting piece, and an explosion section corresponding to the cutting piece; the diameter of the transition section is consistent with the minimum diameter of the conical surface cavity; the diameter of the explosion section is smaller than the diameter of the transition section. The electric explosion valve cutting piece is of a directly machined integrated structure and is simple in process and high in universality.
