Forging process:

The forging process generally consists of the following processes, that is, selecting high-quality steel billet, heating, forming, and cooling after forging. The forging process methods include free forging, die forging and membrane forging. During production, different forging methods are selected according to the quality of the forgings and the size of the production batch. Free forging has low productivity and large machining allowance, but the tools are simple and versatile, so it is widely used for forging single pieces with simple shapes and small batch production of forgings. Free forging equipment includes air hammers, steam air hammers and hydraulic presses, which are suitable for the production of small, medium and large forgings respectively. Die forging has high productivity, simple operation, and easy mechanization and automation. The dimensional accuracy of the die forgings, the small machining allowance, and the more reasonable fiber tissue distribution of the forgings can further increase the service life of the parts.

1. 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.

1. Upsetting Upsetting is an operation process of forging the original blank along the axial direction to reduce its height and increase its cross-section. This process is commonly used for forging gear blanks and other disc-shaped forgings. Upsetting is divided into two types: total upsetting and partial forging.

2. Drawing Drawing is a forging process that increases the length of the blank and reduces the cross-section. It is usually used to produce blanks for shafts, such as lathe spindles, connecting rods, etc.

3. Punching is a forging process in which a punch is used to punch out through-holes or non-through-holes in the blank.

4. Bending is a forging process that bends the blank into a certain angle or shape.

5. Torsion is a forging process that rotates one part of the blank at a certain angle relative to another part.

6. Cutting is the forging process of dividing the blank or cutting off the head.

2. Die forging is called die forging in full. The heated blank is placed in a forging die fixed on the die forging equipment and is forged into shape.

1. The basic process of die forging. The die forging process: blanking, heating, pre-forging, final forging, skin punching, trimming, tempering, and shot blasting. Commonly used processes include upsetting, lengthening, bending, punching, and forming.

2. Commonly used die forging equipment Commonly used die forging equipment include die forging hammers, hot die forging presses, flat forging machines and friction presses. In layman's terms, forged flanges have better quality and are generally produced through die forging. They have fine crystal structure and high strength, but of course they are more expensive.
