The forging process generally consists of the following steps: selecting high-quality billet blanking, heating, forming, and forging cooling. The forging process is free forging, die forging. At the time of production, different forging methods are selected according to the quality of the forgings and the number of production batches.

(1) Free forging

The free forging productivity is low, the machining allowance is large, but the tool is simple and the versatility is large, so it is widely used for forging a single piece and a small batch of forgings with a simple shape. Free forging equipment includes air hammer, steam-air hammer, and hydraulic press, which are suitable for the production of small, medium and large forgings. Flange processing manufacturers look for Titanium machinery. Die forging has high productivity, simple operation, and easy mechanization and automation. The die forgings have high dimensional accuracy, small machining allowance, and the fiber structure distribution of the forgings is more reasonable, which can further improve the service life of the parts.

(2) Die forging

The die forging is collectively referred to as model forging, and the heated blank is placed in a forging die fixed to the die forging device to be forged.

1. The process of die forging: cutting, heating, pre-forging, final forging, punching, trimming, quenching and tempering, shot peening. Commonly used processes are upsetting, lengthening, bending, punching, and forming.

2. Commonly used die forging equipment: Common die forging equipment has to die forging hammer, hot die forging press, flat forging machine, and friction press.

Generally speaking, forged flanges are of better quality, generally produced by die forging, with the fine crystal structure and high strength, of course, the price is also more expensive.

Both the cast flange and the forged flange are common methods of manufacturing flanges. See the strength requirements of the parts to be used. If the requirements are not high, you can also use the turning flange.
