Zusammenfassung:	The utility model provides an oblique flower tooth round nut and a forming device thereof. The oblique flower tooth round nut comprises a head flange, a rod part connected with the head flange and an inner hole penetrating through the head flange and the rod part in the axis direction. The end face, facing the rod part, of the head flange is concaved inwards to form a groove part, and the groove part extends outwards in the radial direction from the outer edge of the rod part. And a plurality of inclined teeth are arranged on the outer wall of the rod part. The groove portion surrounding the rod portion is formed in the lower end face of the head flange of the round nut with the oblique teeth in the inwards-concave mode, the groove portion is formed before the oblique teeth are formed, guiding and length compensation can be provided for a die in the axial direction in the process of shrinking the teeth on the rod portion, the oblique teeth are directly formed without a graining machine, and the machining effi
