The utility model belongs to the technical field of metal punch forming process, and discloses a flanging die which comprises a first die set and a second die set, and the first die set is provided with a hole flanging punch-die and a push block. The supporting part is arranged on the hole flanging punch-die, so that the length of the thin punching part is reduced, the overall strength of the hole flanging punch-die is improved, and the risk that the punching part is damaged due to stress when the first die set and the second die set are subjected to die assembly punching is reduced; through cooperation of the hole flanging convex-concave die, the stamping platform and the convex die, a part to be flanged is flanged and bent, and automatic discharging of the flanged part is completed through sliding of the push block in the first through hole and the second through hole; the technical problems that in the prior art, when small-gap parts are flanged, the production period is long, the production efficiency is
