Abstract

The invention relates to large-scale flange molding equipment and a molding process. The equipment comprises a feed pressing device, a clamping device and a rotating device; the feed pressing device is used for pressing a heating blank material 4 so as to prevent the blank material from tilting and bring a bending force for the blank material so that the blank material can rotate and bend; the clamping device is fixedly arranged under a rotating platform of the rotating device, rotates synchronously along the rotation platform and clamps the blank material simultaneously so that the blank material forms a closed ring; with the rotating device, the blank material clings to a lug boss of the rotating platform and rotates along the rotating platform to form the inside diameter of a needed finished product. The large-scale flange molding equipment has the characteristics of simple process, high machining efficiency, high yield, energy conservation and consumption reduction, and can be widely used for producing a large-scale flange in engineering machinery, petrochemical engineering, wind power generation and other industrial fields.

Description

technical field [0001] The invention relates to process equipment, in particular to a large-scale flange forming equipment and a forming process. Background technique [0002] There are two types of traditional large flange forming equipment and forming processes: [0003] One is the overall forging method through a hydraulic press. After the billet is heated, it is forged into a disc shape and then punched in the middle. After reheating, it is forged into a ring shape; Big. [0004] The other is to use the ring rolling machine to forge and punch the heated billet first, then repeatedly roll it, continuously expand the center hole of the billet, and finally obtain the finished product; this method is complicated in process, low in yield, and difficult to operate the equipment. It occupies a large area, takes a long time to process finished products, and also has the disadvantage of high energy consumption. Contents of the invention [0005] In view of the above-mentione...
