quality BL Flange For sale The forging process generally consists of the following processes, namely, selecting high-quality billets for blanking, heating, forming, and cooling after forging. Forging methods include free forging, die forging and membrane forging. During production, different forging methods are selected according to the quality of forgings and the number of production batches.

　　quality BL Flange For sale Free forging has low productivity and large machining allowance, but the tools are simple and versatile, so it is widely used for forging single-piece and small-batch forgings with relatively simple shapes. Free forging equipment includes air hammer, steam-air hammer and hydraulic press, etc., which are suitable for the production of small, medium and large forgings. Die forging has high productivity, simple operation, and easy mechanization and automation.

　　quality BL Flange For sale The basic process of free forging: during free forging, the shape of the forging is gradually forged from 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 operation process of forging the original billet in the axial direction to reduce its height and increase its cross section. This process is often used for forging gear blanks and other disc-shaped forgings. 2. Elongation. Elongation 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.quality BL Flange For sale Punching. The forging process of punching through holes or non-through holes on the blank with a punch. 4. Bending. The forging process of bending a billet into a certain angle or shape. 5. Torsion. A forging process in which one part of the billet is rotated at a certain angle relative to another part. 6.quality BL Flange For sale cutting. The forging process of splitting the billet or cutting off the head.
