Production process of forged flanges used in rubber joints

The forging process generally consists of the following processes, that is, selecting high-quality steel blanks, 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 and large machining allowance, but the tool is simple and versatile, so it is widely used to forge single-piece and small-batch forgings with simpler 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 commonly used for forging gear blanks and other disc-shaped forgings. Upsetting is divided into two types of upsetting and local forging.
2. Drawing and drawing Drawing is a forging process that increases the length of the billet and reduces the cross section. It is usually used to produce shaft blanks, such as lathe spindles and connecting rods.
3. Forging process for 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 that rotates a part of the billet by a certain angle with respect to another part.
6. Cutting forging process of cutting blank or cutting head.
Second, die forging Die forging is called model forging, and the heated blank is placed in a forging die fixed on the die forging device to be shaped.
1. The basic process of die forging The die forging process: blanking, heating, pre-forging, final forging, punching skin, trimming, quenching and tempering, shot peening. Common processes are upsetting, drawing, bending, punching and forming.
2. Common die forging equipment Common die forging equipment includes die forging hammer, hot die forging press, flat forging press and friction press.
