The production process of forgings is to make the metal plastic flow and make the required shape of the workpiece. The volume of metal is constant after plastic flow caused by external force, and the metal always flows to the part with small resistance. In forging, the shape of forgings is often controlled according to these rules, and the rough shape of forgings is forged by upsetting, drawing, reaming, bending, drawing and other deformation methods. Large batch of forgings to make the size of accurate, conducive to the organization of mass production, can be applied to the mold forming method, the organization of professional mass production or mass production.
The forging process includes blanking, heating and pretreatment before forming. After forming, the forgings are processed by the lathe to cut the margin, and the properties of the forgings are improved through the heat treatment. After finishing cutting, the shape of the forgings meets the requirements of the drawings. After surface treatment and packaging, it can be shipped.
