The invention relates to a steel wire flower twisting mechanism and belongs to the technical field of machining equipment. The steel wire flower twisting mechanism comprises a rack and further comprises a rotating disc arranged on the rack, a central shaft, a profiling mandrel, a plurality of profiling sliders, an involute retainer ring, a guide wire component and a central rotating driving component fixed to the rack, wherein the central shaft is vertically arranged, and the top end of the central shaft is sequentially fixed with the rotating disc and the profiling mandrel; the plurality of profiling sliders are distributed on the rotating disc in the circumferential direction and located at the outer circle of the profiling mandrel; one ends of the plurality of profiling sliders are separately matched with the shape of the side edge of the profiling mandrel, and the other ends of the profiling sliders are in limiting connection with the involute retainer ring; the bottoms of the profiling sliders are in sliding connection with the rotating disc in the circumferential radial direction; and the lower end of the central shaft is fixed with the central rotating driving component. Themanufacture automation problem of large-angle steel wire flowers and specially-shaped steel wire coils is solved.
