What is the die forging of flange

What is the die forging of flange? The die forging of flange is called model forging. The heated flange blank is forged in the forging die fixed on the die forging equipment. 1. basic process of die forging flange die forging process: blanking, heating, pre forging, final forging, punching, edge cutting, tempering and shot blasting. Common processes include upsetting, drawing, bending, punching and forming. 2. common die forging flange equipment includes die forging hammer, hot die forging press, flat forging machine and friction press. Generally speaking, forged flanges are of better quality. Generally, flanges are produced by die forging, with fine crystal structure and high strength. Of course, the price is also more expensive. Both cast flanges and forged flanges are common manufacturing methods for flanges. Depending on the strength requirements of the components to be used, turning flanges can also be selected if the requirements are not high. In addition, flanges are also divided into cut flanges and rolled flanges. Cutting flange refers to directly cutting the inner and outer diameter and thickness of the flange on the middle plate, and then processing the bolt hole and water line. The flange produced in this way is called cut flange. The diameter of this kind of flange is limited to the width of the middle plate. Coiling flange refers to the process of cutting strips with medium plate and then coiling them into a circle, which is called coiling. It is mostly used in the production of some large flanges. After successful rolling, the flange shall be welded, flattened, and then the waterline and bolt hole shall be processed.
