The forging process of forging flange is generally composed of the following processes, that is, selecting high-quality billet blanking, heating, forming, cooling forging process after forging is free forging, die forging and film forging production, according to the size of forging quality, the number of production batches to choose different forging methods.

Free forging has the advantages of low productivity, large machining allowance, simple tools and wide versatility, so it is widely used in forging single piece with simple shape and in small batch production, such as air hammer, steam-air hammer and hydraulic press. Mechanized and automated die forging has high dimensional accuracy, small machining allowance and more reasonable distribution of fiber structure, which can further improve the service life of the basic working procedure of free forging: free forging, the shape of the forging is the basic work of forging the blank gradually through some basic deformation procedures. The sequence is upsetting, drawing, punching, bending and cutting.

1. Upsetting and upsetting is the process of forging the blank along the axis to reduce its height and increase its cross-section. This process is often used to forge gear blanks and other disc-shaped forgings upsetting can be divided into full upsetting and partial upsetting.

2. Drawing is a forging process that increases the length of blank and decreases the cross-section. It is usually used to produce the blank of shaft parts, such as lathe spindle, connecting rod, etc.

3. forging process for punching holes or through holes on billets with punches.

4. forging process of bending the billet into a certain angle or shape.

5. forging process that causes a part of billet to rotate at a certain angle relative to the other part.

6. The forging process of cutting and dividing blanks or cutting heads is called model forging. The heated blanks are forged in a forging die fixed to the forging equipment.

1. The basic process of die forging: blanking, heating, pre-forging, final forging, punching and connecting skin, trimming, quenching and tempering, shot peening commonly used processes are upsetting, elongation, bending, punching, forming

2. Common die forging equipment commonly used die forging equipment hammer, hot die forging press, flat forging machine and friction press, etc.
