Blind flange 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 simple shape.
Free forging equipment includes air hammer, steam air hammer and hydraulic press, which are suitable for the production of small, medium and large forgings respectively.
Die forging has the advantages of high productivity, simple operation and easy mechanization and automation. Die forgings have high dimensional accuracy, small machining allowance, and more reasonable fiber structure distribution of forgings, which can further improve the service life of parts.
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.
1. Upsetting upsetting is the operation process of forging the raw material along the axial direction to reduce its height and increase its cross section. This process is often used to forge gear blanks and other disc forgings. Upsetting is divided into full upsetting and partial upsetting.
2. Lengthening is a forging process that increases the length of the blank and reduces the section. It is usually used to produce shaft blanks, such as lathe spindle, connecting rod, etc.
3. Punching the forging process of punching through holes or through holes on the blank with a punch.
4. The forging process of bending the blank into a certain angle or shape.
5. The forging process in which one part of the blank rotates at a certain angle relative to another part by torsion.
6. Forging process of cutting and dividing blank or cutting head.
