Forming method of concave-convex anti-slip rivet nut for metal plate

The invention discloses a forming method of a concave-convex anti-slip rivet nut for a metal plate, and belongs to the technical field of rivet nut machining. The method comprises the specific steps that firstly, raw materials are beaten into a blank of the rivet nut through a nut machine; 2, the blank material is put into an annealing furnace to be annealed and softened; thirdly, tapping is conducted on the annealed blank through a tapping machine; fourthly, the rivet nut obtained after tapping is completed is put into an oil throwing machine to be subjected to oil throwing dry; wherein the forming equipment of the concave-convex anti-slip rivet nut for the metal plate in the step 3 comprises a bottom plate, and a fixing plate is arranged on the upper side of the bottom plate; a removing mechanism is arranged on the rear side of the surface of the supporting plate and used for removing unqualified rivet nuts when the detection mechanism detects that the anti-skid effect of the rivet nuts is unqualified.
