The forging process generally consists of the following procedures, namely, selecting high-quality steel billets for cutting, heating, forming, and cooling after forging. The forging process methods include free forging, die forging and membrane forging. During production, choose different forging methods according to the quality of forgings and the number of production batches.
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 simpler shapes. Free forging equipment includes air hammer, steam-air hammer and hydraulic press, etc., which are respectively suitable for the production of small, medium and large forgings. Die forging has high productivity, simple operation, and easy realization of mechanization and automation. The die forgings have high dimensional accuracy, small machining allowances, and more reasonable fiber structure distribution of the forgings, which can further improve the service life of the parts.
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.
