brief introduction The utility model has the advantages of compact structure, small volume, low energy consumption, high efficiency, no noise, convenient installation and use, simple operation, strong bearing capacity, long service life, fast rolling speed, reliable product quality and so on. Flange machine is to roll carbon steel, stainless steel and non-ferrous metal profiles into diameter320-6000mm ring and flange is a high-efficiency rounding device. It replaces the original complex processes such as steel plate blanking, butt joint, correction and lathe processing, and saves oxygen, acetylene, labor and raw materials. It is an advanced mother machine for manufacturing flanges. Product introduction The product is widely used in mechanical equipment industries such as fan, bridge formwork, chemical equipment, cable rack, mining explosion-proof switch and centrifuge. The flange forming machine uses the molds on the three rollers to roll various profiles, such as flat steel, channel steel, round pipe or other profiles with special-shaped section, into circular, arc and spiral shapes with certain curvature. The die of the machine is combined, which can be applied to a variety of profiles after changing the combination.
