Production process:
The forging process is generally composed of the following procedures, that is, selecting high-quality steel blanks, heating, forming, and cooling after forging. The forging process methods include free forging, die forging and tire forging. During production, different forging methods are selected according to the quality of 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 for forging single-piece and small-batch forgings with simpler 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 respectively. The productivity of die forging is high, the operation is simple, and it is easy to realize 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.
