The invention belongs to the technical field of machining devices, and particularly relates to a flange flanging machine. The flange flanging machine comprises a machine frame, and a movable tabletop and a fixed tabletop which are arranged on the machine frame. The movable tabletop is perpendicularly turned relative to the fixed tabletop through a rotating support. A conical pressing block is arranged in the middle of the movable tabletop. The bottom of the conical pressing block is connected with a lifting mechanism. An outer-diameter expanding die is arranged outside the movable tabletop. A pressing wheel for pressing the wall of a metal circular pipe and a supporting wheel rotating around the axis are arranged on the fixed tabletop. The pressing wheel is installed in a slide groove. The pressing wheel linearly slides along the slide groove and is a set distance away from the supporting wheel. The supporting wheel is located below the outer diameter expanding die. The outer diameter of the supporting wheel is internally tangent to the outer diameter of the outer diameter expanding die. The flange flanging machine is simple in structure and reasonable in design, flange edges can be directly pressed on the metal circular pipe, the joint strength is enhanced, the product quality is improved, the production efficiency is greatly improved, the subsequent welding, grinding and other procedures are omitted, and the production cost is reduced.
