Production process of forged flange

We understand the production process of forged flanges:
The forging process generally consists of the following procedures, namely, selecting high-quality steel billets, heating, forming, and cooling after forging. The methods of forging include free forging, die forging and membrane forging.
During production, different forging methods are selected according to the quality of the forgings and the number of production batches.
Free forging has low productivity, large machining allowance, but simple tools and great versatility, so it is widely used to forge single-piece and small-batch forgings with simple shapes.
Free forging equipment includes air hammer, steam-air hammer and hydraulic press, which are suitable for the production of small, medium and large forgings.
Die forging has high productivity, simple operation and easy mechanization and automation. Die forgings have high dimensional accuracy, small machining allowances, and more reasonable fiber organization for forgings, which can further increase the service life of parts.
First, the basic process of free forging: During free forging, the shape of the forging is gradually forged into the blank through some basic deformation processes. The basic processes of free forging include upsetting, drawing, punching, bending and cutting.
1. Upsetting Upsetting is the process of forging the original blank in the axial direction to reduce its height and increase its cross section. This process is often used to forge gear blanks and other disc-shaped forgings. Upsetting is divided into two types: upsetting and local forging.
2. Drawing length Drawing length is a forging process that increases the length of the blank and reduces the cross section. It is usually used to produce shaft blanks, such as lathe spindles and connecting rods.
3. Punching The forging process of punching through holes or non-through holes on the blank with a punch.
4. Bending A forging process that bends the billet into a certain angle or shape.
5. Twisting A forging process in which one part of the billet is rotated at a certain angle relative to the other part.
6. Cutting Forging process that divides the blank or cuts the blank.
