The forging process is generally composed of the following processes, that is, selecting high-quality billet blanking, heating, forming, cooling after forging.
Forging process methods are free forging, die forging and membrane forging. Production, according to the size of the quality of forgings, the number of production batch choose different forging methods. Free forging is widely used in forging of single piece and small batch because of its low productivity and large machining allowance, but its tool is simple and universal. Free forging equipment has air hammer, steam-air Hammer and hydraulic press, respectively suitable for the production of small, medium and large forgings. Die Forging has the advantages of high productivity, simple operation, easy mechanization and automation. The precision of die forgings is high, the machining allowance is small, and the fiber structure distribution of forgings is more reasonable, which can further improve the service life of the parts. The basic process of free forging: When free forging, the shape of the forging is gradually forged through some basic deformation procedures. The basic processes of free forging are upsetting, stretching, punching, bending and cutting.
