Rivet scraping device for pressing rivet nut

The utility model discloses a scraping and riveting device for a pressing rivet nut, which is characterized in that a nut main body of the pressing rivet nut is in a polygonal column shape or a circular column shape; a circular barrel-shaped or polygonal barrel-shaped inner mold hole is formed in an inner mold column of the scraping and riveting mold; the diameter of the inner die hole is smaller than the outer diameter of the nut body. When the pressing rivet nut with the polygonal cylindrical nut main body is riveted with a plate, the inner die hole is cylindrical; when the pressing rivet nut with the cylindrical nut body is riveted with a plate, the inner die hole is in a polygonal barrel shape. The convex points formed on the outer peripheral surface of the nut main body extrude a plate between the convex points and the nut rim part; and the convex points are formed on the outer peripheral surface of the nut main body by extruding and scraping the outer peripheral surface of the nut main body through a sc
