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.
Description
technical field [0001] The invention belongs to the field of mechanical processing equipment, and in particular relates to a flange flanging machine. Background technique [0002] After the metal round tube of the fire exhaust fan is processed, according to the process requirements, flanges need to be welded at both ends of the metal tube. The usual practice is to fit the flange to the end of the metal round pipe, and weld the flange neck and the metal round pipe together. However, in actual production, since the end section of the metal round pipe is a circular arc surface, it cannot fit closely with the flange neck. It often requires the cooperation of multiple people to align the flat circular arc surface with a hammer to match the flange, and then Welding on one side is not only labor-intensive and time-consuming, but also makes the labor intensity of workers high, and often produces stress deformation after welding, resulting in poor welding quality. In addition, afte...
