High-flatness stamping structure and sheet metal machining equipment

The invention is suitable for the field of sheet metal machining, and provides a high-flatness stamping structure and sheet metal machining equipment. The high-flatness stamping structure comprises asupporting base, and further comprises a male stamping head, a female stamping head, a sliding transmission assembly, a swing transmission assembly, a different-direction transmission assembly and a driving mechanism, wherein the male stamping head and the female stamping head are used for carrying out stamping forming on a blank, and are arranged on the supporting base in a sliding mode; the sliding transmission assembly is used for enabling the male stamping head and the female stamping head to do linear motion on the supporting base; the swing transmission assembly is used for converting rotation into linear motion so as to enable the sliding transmission assembly to act; the different-direction transmission assembly is used for enabling the female stamping head to synchronously do linear motion in the opposite
